*A VERY MERRY CHRISTMAS AND A HAPPY NEW YEAR 2021 TO ALL MY VIEWERS* Let's all hope that 2021 will be better for us all! Thanks for a great year, everyone.
Hi Ralph, I've missed your videos. You are #1 on my viewing list. Glad to hear that your absence is not because of anything bad. Thank you for inspiring some fun projects. I recently used your gmail code for a mailbox alert, and I have used some of your home alone ideas for a similar project that I am working on. Hurry back!
Ralph! We miss you! Please come back soon! An idea for the next videos: please do an introductory series on the latest Arduino Nano RP2040 Connect board which has the new Raspberry Pi 2040 chip.
Thanks Ralph, for your channel - very enjoyable to listen to your project creations, and I really like that you share your contents on GitHub. The display breakout board is brilliant. I wish you and your family a merry Christmas.
Just a minor correction, an eight bit register rolls over after 256 clocks, not 255. 255 is the maximum number it can show, but zero is one step. Happy holidays
Dear Ralph, thank you so much for all your inspiring videos! I really like to go down this rabbit hole and discover the sparkling world of Arduinos, buzzers, sensors and LEDs. You are a perfect guide in these adventures. What would thrill me to see, in addition to even more of your electronics videos, is a "backstage" video. How do you produce your videos? What equipment do you use? How do you envision and realise a new topic? That sort of stuff. You and all this fine community, stay save and have a great new year.
I'm occasionally asked about the way I make my videos but that would have very limited interest to my (Arduino) viewers. And, to be honest, some of the ways I video and edit took a long, long time to master and improve so I'm probably going to keep that sort of thing close to my chest!
Merry Christmas Ralph, and to the other viewers. Thank you for the gift of another year of helpful videos.. One could desolder the 3.5mm jack and simply run wires to the phone jacks you showed. Probably already thought of by you and others,....
Hi Ralph, hope you are keeping well and the move went smoothly. I’m guessing your wife has prioritised the decorating of the new home over TH-cam and I can quite understand. Don’t overdo it! Wishing you all the best.
Merry X-mas and a happy new year! [edit] Btw.: Wouldn't it make a better choice perhaps to even further reduce cables, by having something like a cheap atmega328pb-au or atmega328pb-mu, I remember you had some lying around, at the display pcb, and have some communication with it like via USART or I2C or SPI? You could reduce the cable stuff down to something like 4 or at least down to 6 cables perhaps and have all the graphics code and lcd driving in a separate device then. That also would offer the choice to change the display without changing the main design portion, as long as the main board only sends like meta-commands of "CMD:This is the radio-name string", "CMD:change brightness to x%" and on the reverse communication direction like "CMD:button y was pressed and released", and so on. Easy to do with USART, but also simple along with I2C/SPI when using an /INT channel wire in addition. Such meta-commands sent, would also work along with any type of display like e.g. character display in combination with hardware buttons, just in case you might change that one day. And in future projects it becomes much easier to integrate such meta-command display interface without much additional work. Perhaps it is over the top, but I would even consider something like USART via RS485 on board, or at least a I2C-slave-display with /INT-channel, if I knew I was going to use components of older projects over and over again in upcoming projects, since this reduces integration of various displays with all the different graphic-controllers, etc. down to some code lines for communication via some common interface on the main project component. Same true for input components like various keyboards/key-fields (QTouch,push buttons,rotary encoders and the like) for programmable-arduino-RPN-calculator, web-radio, etc.pp. projects. But that's just a ad hoc idea to your web radio design. Wish you all the best for your upcoming projects!
A nice idea, Sebastian and I had considered it, basically turning the "dumb" screen into an intelligent one. But I have a Nextion screen here that does just that and which I want to investigate in a future video. I will be able to plug it into the same cable port but only use power and the I2C pins. We shall see. Merry Christmas!
Ralph, once again, thank you for all that you do. I look forward to the education that you provide because you are so good at it! Merry Christmas, Happy New Year and good luck with the move. Don't rush to get back to the youtube - we will all be here when you are ready to make more videos. Cheers! Al
Thanks for the Christmas present :) I wasn't expecting to see a video this week, but was happy to receive it. It was amusing to see your clarifications, as I'd sensed there was some wonkiness but was too busy to take a deeper look. Thankfully you had other viewers you could rely on. In any case, I hope you have a rejuvenating Christmas holiday and I look forward to being welcomed back to your next informative and engaging video.
Hi Ralph. Thanks for the book review, it is very much appreciated and good to know that someone is finding it useful. Happy Christmas, stay safe and good luck "flitting" as we Jocks say for moving house. Cheers, Norm.
You should be proud of that book, and it should be mandatory reading for all high school kids getting started with the Arduino! I hope your sales increase too, of course, after all, 2 years writing is a long time and a lot of effort. I hear you're writing another book now?
Hi Ralph and thanks once again for the videos. I was a bit surprised about the ESP32 board you have chosen? The TTGO T7 V1.4 or !.5 has a much smaller footprint and does not have the TFT and SD card ports. Another option for the "production run" might have been to use a bare Rover module as the pins are quite easy to solder down and only a handful of support components would have been needed, nice project though and good luck with the move.
If I had had the time, Chris, I would have gone for a bare ESP32 WROVER (well, ESP32 16Mb SRAM plus extra 4Mb PSRAM) on a custom PCB but time is one thing I don't have. The TTGO T8 is a generally available module, not too pricey and offer lots of expansion including that built in SD card which works well although I'm not using it in this project for obvious LittleFS reasons! Additionally it can run off a battery with the built in connector and on/off switch. Consider this project a proof-of-concept; anyone can (re-)design my board for whatever hardware they choose an still use my code (still being developed, now I can change station using a pick list, so much easier). Thanks for your good wishes regarding the house move, not stressful at all!
Merry Christmas Ralph, thanks for the incredible content that you so brilliantly share with this community. I can forecast your number of followers will rise very fast!
Thanks Ralph. I know you've had a rough year, but us lot really appreciate what you've done with your videos. Again Thanks Ralph. Merry Christnas, Happy new year. Hoping your 2021 is much much better.
I've been trying to find out more about the IDE you're using for the Arduino C++ programming. Would you post a reference/link, please? I am really enjoying your videos, learning alot. Thanks!
I probably used the Eclipse Sloeber version, but it's no longer being actively developed or supported. The new Arduino IDE is based on Eclipse though so that should be much better when released. Or do what I did and use PlatformIO with Visual Code. eclipse.baeyens.it/
Hi Ralph, Thanks for the tip about your Christmas video with its further information re the wiring of the WebRadio. You may recall that I was trying to breadboard the project but having problems interpreting the schematic. Well the education aspect of your mission has really worked well and spurred me on to study EasyEDA. I understand far better now how the ribbon cable headers are interconnecting the different boards. I have down loaded your GitHub ‘EasyEDA Projects’ folder and opened them in EasyEDA. I have watched your tutorials and I have managed to convert the circuit to a PCB, but you will know that the components are not placed. Given my current level of EasyEDA competence I suspect the chances of getting the layout correct so that it all slots together as it should, are not very high. I think I mentioned that my original plan was to breadboard the radio before going on to make the unit with PCB’s. However I think going straight to the PCB is probably by best way forward. Is there any chance you could share the completed project with us (i.e. with the board layout completed)? I appreciate this might be a bit of a cop out on my part, but if it does exist as a file that would be great. Thanks again and a Happy New Year.
If you find my email address in the ABOUT tab of my channel (not using a phone, it won't work) send me an email and I can send you the pair of PCBs. You will need some other cheap components (eg IDC cables) that I can specify too. Let me know.
I know, I must put in more effort, thanks for the pep talk Andy, I knew I could rely on you! Have a great break (I suspect you're in Tier 4 too, if not now then pretty soon!) and see you in 2021.
Ralph, Merry Christmas from Kalamazoo, Michigan! I’ve enjoyed your videos quite a lot this year. You have a nice approach on the material, and I love your A/V presentation system. In 2021, I’m really looking forward to your treatment of the ESP32 - FreeRTOS - Arduino circus, with perhaps some MicroPython sprinkled in (🧐?) I spent my career doing both PC interfacing and software, in the laboratory environment, and the ESP32 and RasPi would have been fantastic for that. Spent the last couple of decades doing network admin, with ùC on the edges. P.S. My heart goes out to you missing Benny at this time of year. We’re a dog family (Labradors), but animal lovers all.
Thank you for your kind wishes, Preston, and I very much appreciate that you understand how I'm feeling not having Benny here at this special time. In a week's time it will be 4 months since he passed and the pain is still so very real. Yes, let's hope 2021 is a *much better* year all round, and I certainly hope to talk about the ESP32 with FreeRTOS much more; it's an *amazing* chip (as long as it's not a Revision 0 one). All the best for a Happy New Year 2021!
For someone who doesn't put in the effort, you do a pretty dam good job. Thanks and look forward to the next 40. P.S. As an aside thanks for the watchdog board, it's is still in Scotland but I am still in Spain. Promise I will go get it and build it. Happy new year.
OMG, that was some time ago! I guess you won't be returning whilst Scotland is in Tier 4 though. Oh well, Easter will be here soon, all down to Tier 1 by then we hope.
Ralph, I hope that in the new year you will be able to add a followup to Video-189, zero crossing detector, to complete a light dimmer control or motor speed control. I'm learning a lot from your videos, have much more to go. Eric.
I hope so too! Although I no longer have that large fan in my new workshop I intend to have some sort of fan so I still need the control. I have retained all the components so keep tuned!
I just came over to check how you've been. While reading the comments, the video was running and I heard about the JLCPCB 4 layer discount. I ordered two 4 layer PCB's yesterday, totally missing this offer. So, now I know there is a drawback on skipping the sponsor parts of your videos. :-) Usually they are pre-recorded bits, repeating the same stuff in every video in most channels I follow, but now I see you're not one of them :-)) Anyways, I hope everything is fine over there, I wish all the best for you and your family, stay safe and take care!
Always late to the party, hey, Bora! Sorry you missed the 4-layer offer; perhaps they will repeat it for Chinese New Year? I'm moving house soon (bit of a hold up right now). And more eye laser surgery planned. It never stops (things going on in my life, I mean).,
Hey Ralph, how about doing a quick video about electronics parts having in a personal stock. There is not many videos on YT on that topic. I'd love a overview of which of the 74XX/40XX/... series of IC's you recommend having in house. Hope your move is getting along, regards.
Still surrounded by brown boxes, Eddy! On the topic of what components that a self-respecting electronics hobbyist would keep in that is a very good idea and which I'll explore once I'm settled into my new place!
..The edzelfs web radio hooked me out to learn arduino...1st successful project...its still working....dir not come easy thou..but eventually... Control via web base on smartphone
Sounds great! I'm also aware of the superb Edzelf's radio project but decided to do this from the ground up so I could learn stuff too! A sort of White Room development project (except I didn't look at Ed's radio design).
@@RalphBacon ..i had to break 2 pin (6=cs & 7=dcs) on vs1053b and solder jump it to tx & rx since i made it stack on a wemos d1r1, some pin were redundant( WEMOS D1R1 SPI pin)Stack to eliminate dupont cabling (wire-free version) Now the stacked Vs1053b on D1R1 outputs to stereo amp speaker via 5mm stereo to rca cable . Control tone & station on any browser on the same network...also manual change station by touching end on bared wire on A0 works...the only drawback is I not know how to password protect my index.html since uploaded radio.ini which hold radio station address & AP password are exposed on its linked config.html which was initialy uploaded via 192.168.4.1 , resetted to establish connection to router and the internet to stream radio content listed on radio.ini now in spiff storage. Check it out..for alternate opinion...but i must admit i not fully understood what ed wrote ..and there was another esp32 board with sound & buttons built in named LYRA T..mybe if you could prog it for all in one version of "The Ultimate DIY Streaming Radio"...Happy New Year Ralph.. github.com/SurenBono/Alternate_Edzelf_Esp8266_WebRadio_
I'm still coding features in my Web Radio and suspect that in the fullness of time it will be grow nicely. For example, I want to add some preset stations so an IR remote control seems a good choice. Especially now that I have the radio stations read off a text file (LittleFS), so much easier.
Has you heard about ESP32 LYRAT ..sound and button embedded board...just add a display and code a streaming rad it would be the ultimate maker internet radio...
G'day from Australia, I needed an understanding of capacitors, yours came up, and now I want a lemon sandwich biscuit! Could you send some please? Oh!, and the explanation was great. As an Arduino beginner, I sincerely hope that you recommence producing videos. I have subscribed and wait patiently for a notification. Meanwhile I will look at your back catalogue for more unraveling of Arduino mysteries.
A very Merry Christmas and Happy New Year to you and yours. I just had to pick at your correction. The 8 bit counter divides by 256, not 255. Math is hard, ain't it?
@@RalphBacon I think OP is trying to say is that it overflows every 256 counts. So if you want a frequency, you divide by 256, not 255, even though the max value of a uint8_t is 255.
A VERY MERRY CHRISTMAS AND A HAPPY NEW YEAR to you Ralph and your family. Thank you for all your interesting and brain hurting videos, I hope your move has gone smoothly and can't wait for your next video in 2021:-)
I've not noticed any reduction in bass response using the transformers (or the Aukey device either), although I do have it going through a mixer that has separate bass and treble controls. Unfortunately I don't have the spec sheet for them, but as the inductance is 290mH the inductive reactance at 60Hz would be 109ohms - does that help? If you're in the UK let me know as I have a spare PCB. Specification: Brand new Color: Red Model: EI14 Material: Nickel alloy AC impedance: EI14 600 : 600 Ohm Item: Audio transformer Inductance: 290mH (±20%) DC resistance: 135(±%) Windability: Double-wire winding Quality &wire diameter: QA-1 0.06MM Primary coils: 800 turns Secondary coils: 800 turns Alternating-current impedance value: 600 Selection of quality, long life EMC, EMI, high pressure, stable performance High efficiency transformer
I'm still suspicious of the calc. An 8-bit counter has 256 separate counts (zero is one of them). So, shouldn't you have divided by 256 in your calc? (Chapter 8 in Dunbar's book !) I've learnt a lot from your videos. Thanks very much for sharing them.
Indeed, Alexey. The most recent schematics for both boards (the TFT screen is on a separate PCB in my design) can be found here: github.com/RalphBacon/205-Internet-Radio
@@RalphBacon Another project, ESP32 comms board for a bigger project. ESP reads a number of arduino nodes via NRF24L01, receives cmds via SMS, updates thingspeak over 2G (no wifi) and ESPNow to a main display using another ESP32/Teensy3.6 combination. Wanted to fit a decent display to the ESP hub for a status capability. This tidy's up the wiring nicely, will just update the hub pcb to suit. I'm another JLCPCB user :)
Merry Christmas and congratulations on your 30k subscriber mark. Looking forward to your channel in 2021. How long did it take you to get to 30k subscribers? Keep broadcasting!!
Long story short: retinal detachment in both eyes, cataracts in both eyes, laser surgery in left eye. Still have problems but an improvement on how it used to be!
@@RalphBacon Wow ! seems like your going though the wars there , Thanks for the quick reply , it must be difficult to make videos With all that going on , it’s a bad time to get anything done medically with c19 Floating around , hope you get it sorted soon and keep the vids coming … My long story sort : cataracts in both eyes came on suddenly 6 months ago Find it very hard to drive at night with head light glare , all my computers ,phones ect Are now in dark mode , I wish I was 21 again hahaha all the best for now Aidan
Hi Ralph! Just a quick question for whenever you get a computer running again, after the horrors of moving to a new house. I spied the very interesting breadboard you used in this last video, the one with 3 gutters and binding posts on the end. I’d like to try one of those, but I can’t find them anywhere? Are they still made? Could you post a link? Happy New Year!
Did you mean this one: coolcomponents.co.uk/products/ad-11-advanced-solderless-breadboard As you see it (a) is from a UK supplier but may be available elsewhere and (b) is it not cheap but then again I've not had any issues inserting components in this one (unlike the cheap Asian varieties). I guess you do get what you pay for, sometimes!
I never tried it, Luc, as it seems to convert 5v DC to 5v DC by some sort of switching arrangement. I don't think it's the way to go. But the small transformers I showed work a treat. I'm designing a tiny PCB for them now.
Ralph, thanks for all the videos! Happy New year! And a question about the internet radio... Would it be possible to display the cover art of the playing track (if the station sends them)? I should think it is somewhere in the metadata? If it is jpg i think the esp32 micro is too small, if it is bmp format maybe? I have a Sonos, and missing the display of my older Logitech internet radio.
@@RalphBacon Thanks, so maybe that url is a link to the cover art jpg on the stations server? On my logitech, when a new song starts, it takes about 5 seconds before displaying the picture of that record. Some stations are only displaying a fixed picture, the station logo.
OK, you're sort of correct. I'm listening to "Mellow Magic" right now and the Metadata looks like this: 'I'll Be Home For Christmas - Michael Buble;StreamUrl='listenapi.planetradio.co.uk/api9/eventdata/67090539'; The StreamUrl mentioned look like this (JSON): {"eventId":67090539,"eventStart":"2020-12-27 18:37:37","eventFinish":"2020-12-27 18:42:04","eventDuration":256,"eventType":"Song","eventSongTitle":"I'll Be Home For Christmas","eventSongArtist":"Michael Bubl\u00e9","eventImageUrl":"assets.planetradio.co.uk/track/26447.jpg?ver=1499220544","eventImageUrlSmall":"assets.planetradio.co.uk/track/160x160/26447.jpg?ver=1499220544","eventAppleMusicUrl":"geo.itunes.apple.com/dk/album/669831882?i=669831931"} And buried in that is indeed the album cover art: assets.planetradio.co.uk/track/26447.jpg? Hmm. I wonder if more radio stations do this. More things to explore!
happy new year Ralph, i thought id take the time to wish you a happy new year and thankyou for all your help on my projects last year, thanks to you and your videos, i was able to create a talking rfid motorcycle system, that is due to be modified for my car. a working keyless rfid safe . and a working rfid lock modification that fits any upvc door ( not showed you this one yet but its been on my house for 2 weeks without fault.). now i have set my standards a little higher and got my self a nice challenge , which i was wondering if you would be able to assist with , as i believe it will serve as useful content for others trying to learn this craft, so... i would like to combine a bare bones micro sd card to a esp32, to create a wifi based data exchange point. use sdmcc 4 bit to transfer the data. ie , the unit get plugs in, up pops a WIFI connection on my phone or pc, and when i connect to it i am met with an interface where i can upload to and download files from... like a wifi usb stick. but made on an esp32.
That sounds fascinating, Paul, but right now (as you know) I'm gearing up big time for my move (fingers crossed, so stressful, surrounds by cardboard boxes) so I will have no time to try things like this out. That said, you seem to be doing pretty well without me! When I'm in my new workshop (I'm aiming for Easter, all things being equal, and if I don't run out of money!) then I will be in a position to do more of this sort of thing. But you've got me thinking already. A WiFi-based data exchange point. As Spock might have said, "Fascinating". Thinking about it, the ESP32 can certainly start up a WiFi AP, to which you could connect. Downloading files _from_ it, would be easy enough (simple web page with files listed, click on it and do a GET) but uploading requires that the ESP32 accepts the request from your phone etc. I'll have a think whilst I pack yet more brown boxes.
@@RalphBacon i hope your move goes well... i hope to add a qi ic and a coil to the underside to give it wireless power. Thus creating the first personal data storage implant. i made a working proof of concept yestiday with off the shelf parta but its far to big..its 60x40x5mm.
Progress report. We have a working spi esp32 html interface . We have just made it a local ip. But the speeds are terrible. Having issues running mmc. Exploring the flashair wifi sd cards. And looking at printing a custom flex qi pcv. To stick to the wifi sd. Flashair has been heavily user modified. So i hope i can just change the interface and call it a day.
Excellent suggestions! In fact, as a retrofit, the transformers could be secured under the MP3 board right now, as is. Turning the MP3 board around had been considered but the 3.5mm jack plug then sticks out the "wrong side", if you get what I mean, which at the moment is nice and flush. But, that said, with a right angle adapter it would not be too bad at all, depending on the size of the case. As it happens I have designed a small PCB to hold the transformers so I can use them in my case - I might be able to show these in a future video. Are you thinking of building the ESP32 Web Radio?
@@RalphBacon I've been gathering components for weeks! Great video's, now my preferred method of learning for the Arduino / ESP32. I just need to 'take the plunge'!
Thanks for all your help. I appreciate that you are busy moving but wondered if I might post this request for help in the hope that a fellow arduinite might be able to assist?

@@RalphBacon Thanks Ralph. Issue was actually solved momentarily by loading the correct code. However following the ‘magic smoke’ issue I had no spare therefore had to order a replacement ESP32 board. So progress paused until the replacement arrives.
@@RalphBacon New ESP32 arrived this morning, it all now works hooray! This is with PSRAM disabled, enabling it causes a continuous reboot as before. Looking at the terminal output I notice ‘PSRAM = 0’. I tried reducing the circular buffer size to 10K as you suggested, but if any thing, this increases the frequency of reboots. I remember you mentioned a hack that I don’t think I have incorporated, so I will investigate this further. Almost there.
There is a new version that works with the Arduino IDE (I'm assuming that's what you are using) and some instructions on how to enable the circular buffer (which I recommend you do AFTER you have it working with a 10000 circular buffer set in the main.h). github.com/RalphBacon/205-Internet-Radio/tree/main/Arduino%20IDE%20Version

Sorry @@RalphBacon, my Hitchhiker's Guide reference was way too obscure... but anyway, thank you for all the great videos. This novice has learned a great deal from them.
Nice of you to say, Dave. My (final?) eye op is tomorrow so that's a positive (for me) and means I can see my empty workshop better. Oh. Maybe not then.
Yes, I know, it's been "mentioned" before! The good news is that the ISR frequency changes, from my calc of 3.829656, to 3.814697 Hz. We'll live with that.

Wishing you a very happy new year for 2021. Have really enjoyed your videos throughout 2020. Keep them up for 2021, I will be watching.
Thank you! You too!
Merry Christmas and Happy New Year!
Happy holidays!
Just a minor correction, an eight bit register rolls over after 256 clocks, not 255. 255 is the maximum number it can show, but zero is one step. Happy holidays
Yes, I knew that, but I'm correcting a correction!!! After 255 the overflow happens, that will have to do! Happy holidays!
Dear Ralph, thank you so much for all your inspiring videos! I really like to go down this rabbit hole and discover the sparkling world of Arduinos, buzzers, sensors and LEDs. You are a perfect guide in these adventures.
What would thrill me to see, in addition to even more of your electronics videos, is a "backstage" video. How do you produce your videos? What equipment do you use? How do you envision and realise a new topic? That sort of stuff.
You and all this fine community, stay save and have a great new year.
I'm occasionally asked about the way I make my videos but that would have very limited interest to my (Arduino) viewers. And, to be honest, some of the ways I video and edit took a long, long time to master and improve so I'm probably going to keep that sort of thing close to my chest!
Ralph,
Thank you for taking the time and effort to put together all of these informative videos.

Very welcome! Merry Christmas!
Just bought the book (via affiliate link) - another Christmas gift for me! Merry Christmas Ralph and family.
Awesome! Thank you!
Hope you find the book useful. Enjoy, and thanks for buying it.
Merry Christmas Ralph, and to the other viewers. Thank you for the gift of another year of helpful videos..
One could desolder the 3.5mm jack and simply run wires to the phone jacks you showed. Probably already thought of by you and others,....
Yes, you could do what you suggest, Kent, whatever works for the maker! Merry Xmas to you too and a Happier New Year!
Merry Christmas. Hope the move goes well and you're back in the new year.
I hope so too!
Hi Ralph, hope you are keeping well and the move went smoothly. I’m guessing your wife has prioritised the decorating of the new home over TH-cam and I can quite understand. Don’t overdo it! Wishing you all the best.
Yes, thank you, all the jobs are now... I was going to say "done" but work in a new-ish house is never "done". But at least I'm back on line!
Merry X-mas and a happy new year!
[edit] Btw.: Wouldn't it make a better choice perhaps to even further reduce cables, by having something like a cheap atmega328pb-au or atmega328pb-mu, I remember you had some lying around, at the display pcb, and have some communication with it like via USART or I2C or SPI? You could reduce the cable stuff down to something like 4 or at least down to 6 cables perhaps and have all the graphics code and lcd driving in a separate device then. That also would offer the choice to change the display without changing the main design portion, as long as the main board only sends like meta-commands of "CMD:This is the radio-name string", "CMD:change brightness to x%" and on the reverse communication direction like "CMD:button y was pressed and released", and so on. Easy to do with USART, but also simple along with I2C/SPI when using an /INT channel wire in addition. Such meta-commands sent, would also work along with any type of display like e.g. character display in combination with hardware buttons, just in case you might change that one day. And in future projects it becomes much easier to integrate such meta-command display interface without much additional work. Perhaps it is over the top, but I would even consider something like USART via RS485 on board, or at least a I2C-slave-display with /INT-channel, if I knew I was going to use components of older projects over and over again in upcoming projects, since this reduces integration of various displays with all the different graphic-controllers, etc. down to some code lines for communication via some common interface on the main project component. Same true for input components like various keyboards/key-fields (QTouch,push buttons,rotary encoders and the like) for programmable-arduino-RPN-calculator, web-radio, etc.pp. projects.
But that's just a ad hoc idea to your web radio design. Wish you all the best for your upcoming projects!
A nice idea, Sebastian and I had considered it, basically turning the "dumb" screen into an intelligent one. But I have a Nextion screen here that does just that and which I want to investigate in a future video. I will be able to plug it into the same cable port but only use power and the I2C pins. We shall see. Merry Christmas!
Ralph, once again, thank you for all that you do. I look forward to the education that you provide because you are so good at it! Merry Christmas, Happy New Year and good luck with the move. Don't rush to get back to the youtube - we will all be here when you are ready to make more videos. Cheers! Al
You are very welcome, see you around!
Thanks for the Christmas present :) I wasn't expecting to see a video this week, but was happy to receive it. It was amusing to see your clarifications, as I'd sensed there was some wonkiness but was too busy to take a deeper look. Thankfully you had other viewers you could rely on.
In any case, I hope you have a rejuvenating Christmas holiday and I look forward to being welcomed back to your next informative and engaging video.
Happy holidays, Dale! Fingers crossed for the move!
@@RalphBacon ah yes. The move. Sliped my mind (as do many things, these days). Here's hoping all goes smoothly.
Happy New Year, Thanks for all your videos and keep them up. Cheers Dave.
Thanks, you too!
Merry Christmas Ralph and all the best for the New Year.
Happy holidays!
Hi Ralph. Thanks for the book review, it is very much appreciated and good to know that someone is finding it useful.
Happy Christmas, stay safe and good luck "flitting" as we Jocks say for moving house.
Cheers,
Norm.
You should be proud of that book, and it should be mandatory reading for all high school kids getting started with the Arduino! I hope your sales increase too, of course, after all, 2 years writing is a long time and a lot of effort. I hear you're writing another book now?
@@RalphBacon Thanks again. I am indeed writing another. Arduino (and AVR) Interrupts. All explained in detail and demonstrated.
Merry Christmas. Thanks for all the hard work.
Thank you too!
Hi Ralph and thanks once again for the videos. I was a bit surprised about the ESP32 board you have chosen? The TTGO T7 V1.4 or !.5 has a much smaller footprint and does not have the TFT and SD card ports. Another option for the "production run" might have been to use a bare Rover module as the pins are quite easy to solder down and only a handful of support components would have been needed, nice project though and good luck with the move.
If I had had the time, Chris, I would have gone for a bare ESP32 WROVER (well, ESP32 16Mb SRAM plus extra 4Mb PSRAM) on a custom PCB but time is one thing I don't have. The TTGO T8 is a generally available module, not too pricey and offer lots of expansion including that built in SD card which works well although I'm not using it in this project for obvious LittleFS reasons! Additionally it can run off a battery with the built in connector and on/off switch.
Consider this project a proof-of-concept; anyone can (re-)design my board for whatever hardware they choose an still use my code (still being developed, now I can change station using a pick list, so much easier).
Thanks for your good wishes regarding the house move, not stressful at all!
Merry Christmas Ralph, thanks for the incredible content that you so brilliantly share with this community. I can forecast your number of followers will rise very fast!
Sounds great! Let's hope so, despite my imminent absence!
@@RalphBacon absence, are you all right? Hope so!
Thanks Ralph.
I know you've had a rough year, but us lot really appreciate what you've done with your videos.
Again Thanks Ralph.
Merry Christnas, Happy new year.
Hoping your 2021 is much much better.
I appreciate that. Roll on 2021, thanks Jason.,
I've been trying to find out more about the IDE you're using for the Arduino C++ programming. Would you post a reference/link, please? I am really enjoying your videos, learning alot. Thanks!
I probably used the Eclipse Sloeber version, but it's no longer being actively developed or supported. The new Arduino IDE is based on Eclipse though so that should be much better when released. Or do what I did and use PlatformIO with Visual Code.

Happy Christmas Ralph! Thanks for producing such consistently interesting content.
My pleasure!
Thank's for your awesome work in 2020, Ralph.
My pleasure! See you in the New Year, Pekka!
Hi Ralph, Thanks for the tip about your Christmas video with its further information re the wiring of the WebRadio. You may recall that I was trying to breadboard the project but having problems interpreting the schematic. Well the education aspect of your mission has really worked well and spurred me on to study EasyEDA. I understand far better now how the ribbon cable headers are interconnecting the different boards. I have down loaded your GitHub ‘EasyEDA Projects’ folder and opened them in EasyEDA. I have watched your tutorials and I have managed to convert the circuit to a PCB, but you will know that the components are not placed. Given my current level of EasyEDA competence I suspect the chances of getting the layout correct so that it all slots together as it should, are not very high. I think I mentioned that my original plan was to breadboard the radio before going on to make the unit with PCB’s. However I think going straight to the PCB is probably by best way forward. Is there any chance you could share the completed project with us (i.e. with the board layout completed)? I appreciate this might be a bit of a cop out on my part, but if it does exist as a file that would be great.
Thanks again and a Happy New Year.
Before I answer any of those questions, can I ask whether you are in the UK?
@@RalphBacon Yes I am in Hampshire
If you find my email address in the ABOUT tab of my channel (not using a phone, it won't work) send me an email and I can send you the pair of PCBs. You will need some other cheap components (eg IDC cables) that I can specify too. Let me know.
Email on the way.

Merry Christmas to you and your family. Thanks for all your videos.
Happy holidays!
Ralph, Merry Christmas from Kalamazoo, Michigan! I’ve enjoyed your videos quite a lot this year. You have a nice approach on the material, and I love your A/V presentation system. In 2021, I’m really looking forward to your treatment of the ESP32 - FreeRTOS - Arduino circus, with perhaps some MicroPython sprinkled in (🧐?) I spent my career doing both PC interfacing and software, in the laboratory environment, and the ESP32 and RasPi would have been fantastic for that. Spent the last couple of decades doing network admin, with ùC on the edges.
P.S. My heart goes out to you missing Benny at this time of year. We’re a dog family (Labradors), but animal lovers all.
Thank you for your kind wishes, Preston, and I very much appreciate that you understand how I'm feeling not having Benny here at this special time. In a week's time it will be 4 months since he passed and the pain is still so very real.
Yes, let's hope 2021 is a *much better* year all round, and I certainly hope to talk about the ESP32 with FreeRTOS much more; it's an *amazing* chip (as long as it's not a Revision 0 one).
All the best for a Happy New Year 2021!
Best wishes to you and thanks for the excellent videos. 🎄
Happy holidays!
Happy Christmas to you and your family and many thanks for all the great videos.
Happy holidays!
For someone who doesn't put in the effort, you do a pretty dam good job. Thanks and look forward to the next 40.
P.S. As an aside thanks for the watchdog board, it's is still in Scotland but I am still in Spain. Promise I will go get it and build it. Happy new year.
OMG, that was some time ago! I guess you won't be returning whilst Scotland is in Tier 4 though. Oh well, Easter will be here soon, all down to Tier 1 by then we hope.
@@RalphBacon Fingers crossed.
Happy Christmas to you and family take good care of you (and family)for the next year!!!
Same to you, Pierre!
Great project, thanks for everything, all the best for 2021
Happy new year!
Ralph, I hope that in the new year you will be able to add a followup to Video-189, zero crossing detector, to complete a light dimmer control or motor speed control. I'm learning a lot from your videos, have much more to go. Eric.
I hope so too! Although I no longer have that large fan in my new workshop I intend to have some sort of fan so I still need the control. I have retained all the components so keep tuned!
Thank you Ralph for the exceptional videos you have made all through 2020 🥇
I wish you a happy christmas and a wonderful new year 🎆
Happy holidays!
Merry Christmas Ralph and thanks for all the interesting videos.
Very welcome!
Merry Christmas Ralph and family !

Happy belated new year, wondered why you were so quiet but seen the comments so, hopefully getting sorted and see you soon.
It's been a while, hasn't it? Keep tuned!
That’s the one, Ralph! Many thanks for the link, and have a Happy New Year!
Glad I could help!
I just came over to check how you've been. While reading the comments, the video was running and I heard about the JLCPCB 4 layer discount. I ordered two 4 layer PCB's yesterday, totally missing this offer. So, now I know there is a drawback on skipping the sponsor parts of your videos. :-) Usually they are pre-recorded bits, repeating the same stuff in every video in most channels I follow, but now I see you're not one of them :-)) Anyways, I hope everything is fine over there, I wish all the best for you and your family, stay safe and take care!
Always late to the party, hey, Bora! Sorry you missed the 4-layer offer; perhaps they will repeat it for Chinese New Year?
I'm moving house soon (bit of a hold up right now). And more eye laser surgery planned. It never stops (things going on in my life, I mean).,
Hey Ralph, how about doing a quick video about electronics parts having in a personal stock. There is not many videos on YT on that topic. I'd love a overview of which of the 74XX/40XX/... series of IC's you recommend having in house. Hope your move is getting along, regards.
Still surrounded by brown boxes, Eddy! On the topic of what components that a self-respecting electronics hobbyist would keep in that is a very good idea and which I'll explore once I'm settled into my new place!
Thanks for doing all the videos! I've learned a pretty good bit. Can't wait to see the next projects! Happy holidays!!
Thanks for watching, Mike!

..The edzelfs web radio hooked me out to learn arduino...1st successful project...its still working....dir not come easy thou..but eventually... Control via web base on smartphone
Sounds great! I'm also aware of the superb Edzelf's radio project but decided to do this from the ground up so I could learn stuff too! A sort of White Room development project (except I didn't look at Ed's radio design).
@@RalphBacon
..i had to break 2 pin (6=cs & 7=dcs) on vs1053b and solder jump it to tx & rx since i made it stack on a wemos d1r1, some pin were redundant( WEMOS D1R1 SPI pin)Stack to eliminate dupont cabling (wire-free version)
Now the stacked Vs1053b on D1R1 outputs to stereo amp speaker via 5mm stereo to rca cable . Control tone & station on any browser on the same network...also manual change station by touching end on bared wire on A0 works...the only drawback is I not know how to password protect my index.html since uploaded radio.ini which hold radio station address & AP password are exposed on its linked config.html which was initialy
uploaded via 192.168.4.1 , resetted to establish connection to router and the internet to stream radio content listed on radio.ini now in spiff storage.
Check it out..for alternate opinion...but i must admit i not fully understood what ed wrote ..and there was another esp32 board with sound & buttons built in named LYRA T..mybe if you could prog it for all in one version of "The Ultimate DIY Streaming Radio"...Happy New Year
Ralph..
github.com/SurenBono/Alternate_Edzelf_Esp8266_WebRadio_
I'm still coding features in my Web Radio and suspect that in the fullness of time it will be grow nicely. For example, I want to add some preset stations so an IR remote control seems a good choice. Especially now that I have the radio stations read off a text file (LittleFS), so much easier.
Has you heard about ESP32 LYRAT ..sound and button embedded board...just add a display and code a streaming rad it would be the ultimate maker internet radio...
Merry Christmas Ralph!

G'day from Australia,
I needed an understanding of capacitors, yours came up, and now I want a lemon sandwich biscuit! Could you send some please?
Oh!, and the explanation was great.
As an Arduino beginner, I sincerely hope that you recommence producing videos.
I have subscribed and wait patiently for a notification.
Meanwhile I will look at your back catalogue for more unraveling of Arduino mysteries.
I did send some cream sandwich biscuits to you, Paco, but I'm afraid the postman must have eaten them all!
A very Merry Christmas and Happy New Year to you and yours. I just had to pick at your correction. The 8 bit counter divides by 256, not 255. Math is hard, ain't it?
Hang on, 1, 2, 3... 254, 255 then the overflow. Let me try that again. 1, 2, 3... Too much Christmas Day, have a good one John.
@@RalphBacon I think OP is trying to say is that it overflows every 256 counts. So if you want a frequency, you divide by 256, not 255, even though the max value of a uint8_t is 255.
@@zetaconvex1987 exactly. Picky, picky, picky.

How is the low-frequency response of those tiny isolation transformers? I'm really interested in building up the Web Radio project!
I've not noticed any reduction in bass response using the transformers (or the Aukey device either), although I do have it going through a mixer that has separate bass and treble controls. Unfortunately I don't have the spec sheet for them, but as the inductance is 290mH the inductive reactance at 60Hz would be 109ohms - does that help? If you're in the UK let me know as I have a spare PCB.

Alternating-current impedance value: 600
Selection of quality, long life
EMC, EMI, high pressure, stable performance

How is the new workshop coming along?
Built. Complete. Video on the way.
@@RalphBacon Great! Congratulations, I hope it will bring you much joy!,
I'm still suspicious of the calc. An 8-bit counter has 256 separate counts (zero is one of them). So, shouldn't you have divided by 256 in your calc? (Chapter 8 in Dunbar's book !)
I've learnt a lot from your videos. Thanks very much for sharing them.
Good point! Once the interrupt has counted up 255 interrupts it is the _next_ one that overflows and triggers the ISR, so 256 is correct.
Greetings to you Ralph S Bacon. Is it possible to find out which pins of ESP 32 VS1053 and TFT IPS 240x320 are connected to.
Indeed, Alexey. The most recent schematics for both boards (the TFT screen is on a separate PCB in my design) can be found here:

Marry Christmas Ralph from Livonia Michigan USA and thank you for your very informative videos
Happy holidays! I guess you'll be getting snow in Michigan, right?
Like the display pcb....ordered! lol, nice design. All the best.
Awesome! Are you building the Web Radio project or is that for another project?
@@RalphBacon Another project, ESP32 comms board for a bigger project. ESP reads a number of arduino nodes via NRF24L01, receives cmds via SMS, updates thingspeak over 2G (no wifi) and ESPNow to a main display using another ESP32/Teensy3.6 combination. Wanted to fit a decent display to the ESP hub for a status capability. This tidy's up the wiring nicely, will just update the hub pcb to suit. I'm another JLCPCB user :)
Wish JLCPCB would offer FPC/FFC connectors in assembly. Sadly they don't, so I have to use pcbway.
They are continuing to expand their capabilities so keep tuned to their website!

Hi Ralph! Just a quick question for whenever you get a computer running again, after the horrors of moving to a new house. I spied the very interesting breadboard you used in this last video, the one with 3 gutters and binding posts on the end. I’d like to try one of those, but I can’t find them anywhere? Are they still made? Could you post a link? Happy New Year!
Did you mean this one:
coolcomponents.co.uk/products/ad-11-advanced-solderless-breadboard
As you see it (a) is from a UK supplier but may be available elsewhere and (b) is it not cheap but then again I've not had any issues inserting components in this one (unlike the cheap Asian varieties).
I guess you do get what you pay for, sometimes!
Look forward to your return. Pace your self I would hate to have you get TH-cam burnout.
So the b0505s didn't work to fix the ground loop?
I never tried it, Luc, as it seems to convert 5v DC to 5v DC by some sort of switching arrangement. I don't think it's the way to go. But the small transformers I showed work a treat. I'm designing a tiny PCB for them now.
Ralph, thanks for all the videos! Happy New year! And a question about the internet radio... Would it be possible to display the cover art of the playing track (if the station sends them)? I should think it is somewhere in the metadata? If it is jpg i think the esp32 micro is too small, if it is bmp format maybe? I have a Sonos, and missing the display of my older Logitech internet radio.
Not possible, Eddy. Nothing like this comes down the Metadata, just the artist and track name, sometimes the URL of the radio station URL. That's all!
@@RalphBacon Thanks, so maybe that url is a link to the cover art jpg on the stations server? On my logitech, when a new song starts, it takes about 5 seconds before displaying the picture of that record. Some stations are only displaying a fixed picture, the station logo.
OK, you're sort of correct. I'm listening to "Mellow Magic" right now and the Metadata looks like this:
'I'll Be Home For Christmas - Michael Buble;StreamUrl='listenapi.planetradio.co.uk/api9/eventdata/67090539';
The StreamUrl mentioned look like this (JSON):
{"eventId":67090539,"eventStart":"2020-12-27 18:37:37","eventFinish":"2020-12-27 18:42:04","eventDuration":256,"eventType":"Song","eventSongTitle":"I'll Be Home For Christmas","eventSongArtist":"Michael Bubl\u00e9","eventImageUrl":"assets.planetradio.co.uk/track/26447.jpg?ver=1499220544","eventImageUrlSmall":"assets.planetradio.co.uk/track/160x160/26447.jpg?ver=1499220544","eventAppleMusicUrl":"geo.itunes.apple.com/dk/album/669831882?i=669831931"}
And buried in that is indeed the album cover art:
assets.planetradio.co.uk/track/26447.jpg?
Hmm. I wonder if more radio stations do this. More things to explore!
In fact, there are two images, one small one (ideal for this project) and a larger one. So much to do, so little time!
I know your big arduino, but have you seen the new raspberry pi pico micro controller? it looks fairly special bit of kit.
Maybe, but have you seen this: www.tomshardware.com/uk/news/arduino-rp2040
@@RalphBacon A direct competitor to esp32 and a true Arduino. Wow, that is BIG news.
happy new year Ralph, i thought id take the time to wish you a happy new year and thankyou for all your help on my projects last year, thanks to you and your videos, i was able to create a talking rfid motorcycle system, that is due to be modified for my car. a working keyless rfid safe . and a working rfid lock modification that fits any upvc door ( not showed you this one yet but its been on my house for 2 weeks without fault.). now i have set my standards a little higher and got my self a nice challenge , which i was wondering if you would be able to assist with , as i believe it will serve as useful content for others trying to learn this craft, so... i would like to combine a bare bones micro sd card to a esp32, to create a wifi based data exchange point. use sdmcc 4 bit to transfer the data. ie , the unit get plugs in, up pops a WIFI connection on my phone or pc, and when i connect to it i am met with an interface where i can upload to and download files from... like a wifi usb stick. but made on an esp32.
That sounds fascinating, Paul, but right now (as you know) I'm gearing up big time for my move (fingers crossed, so stressful, surrounds by cardboard boxes) so I will have no time to try things like this out. That said, you seem to be doing pretty well without me!
When I'm in my new workshop (I'm aiming for Easter, all things being equal, and if I don't run out of money!) then I will be in a position to do more of this sort of thing. But you've got me thinking already. A WiFi-based data exchange point. As Spock might have said, "Fascinating".
Thinking about it, the ESP32 can certainly start up a WiFi AP, to which you could connect. Downloading files _from_ it, would be easy enough (simple web page with files listed, click on it and do a GET) but uploading requires that the ESP32 accepts the request from your phone etc. I'll have a think whilst I pack yet more brown boxes.
@@RalphBacon i hope your move goes well... i hope to add a qi ic and a coil to the underside to give it wireless power. Thus creating the first personal data storage implant. i made a working proof of concept yestiday with off the shelf parta but its far to big..its 60x40x5mm.
Size, for a prototype, really doesn't matter. The fact you got a working prototype means you now concentrate on physical design. Good show!
@@RalphBacon we can crack open the champagne when the v2 works ;)
Progress report. We have a working spi esp32 html interface . We have just made it a local ip. But the speeds are terrible. Having issues running mmc. Exploring the flashair wifi sd cards. And looking at printing a custom flex qi pcv. To stick to the wifi sd. Flashair has been heavily user modified. So i hope i can just change the interface and call it a day.

@@RalphBacon Good to see you're still in the land of the living. Looking forward to the inaugural video from the new workshop.
As the MP3 board only plugs in with cables, just turn it 180 degrees and have the audio jack out the other way.
The audio isolation transformers could also go under the MP3 board - just use bigger stand offs.
Excellent suggestions! In fact, as a retrofit, the transformers could be secured under the MP3 board right now, as is.
Turning the MP3 board around had been considered but the 3.5mm jack plug then sticks out the "wrong side", if you get what I mean, which at the moment is nice and flush. But, that said, with a right angle adapter it would not be too bad at all, depending on the size of the case.
As it happens I have designed a small PCB to hold the transformers so I can use them in my case - I might be able to show these in a future video. Are you thinking of building the ESP32 Web Radio?
@@RalphBacon I've been gathering components for weeks! Great video's, now my preferred method of learning for the Arduino / ESP32. I just need to 'take the plunge'!

Thanks for all your help. I appreciate that you are busy moving but wondered if I might post this request for help in the hope that a fellow arduinite might be able to assist?
WEB Radio problems:
Programmed using the Arduino IDE. DATA folder (with intro.mp3 & WiFiSecrets.txt) is contained in same folder as sketch. Board is ICQUANZX T8 V1.7 ESP32 4MB PSRAM TF Card (reports V1 while compiling)
ESP32 Data Upload (LittleFS) carried out before upload of main sketch.
Code used is Ralph’s Arduino code ported from his PlatformIO project.
Screen illuminated but no info. No sound. Also disconnected screen and used ‘NEXT’ switch no change.
Voltages checked on both boards both 3v3 and 5v present and correct.
Project Aborts and Reboots continuously as per port output detailed below:

Problem sorted. I think I was using the wrong code. Momentarily worked and output mp3 but after loadig Littlefs got 'magic smoke'. Dont understand the link, but certainly a lot further on, Cheers
Go to "main.h" and reduce the 150000 (150K) circular buffer to 10000 (10K). Let me know if that doesn't fix the rebooting.
@@RalphBacon Thanks Ralph. Issue was actually solved momentarily by loading the correct code. However following the ‘magic smoke’ issue I had no spare therefore had to order a replacement ESP32 board. So progress paused until the replacement arrives.
@@RalphBacon New ESP32 arrived this morning, it all now works hooray!
This is with PSRAM disabled, enabling it causes a continuous reboot as before. Looking at the terminal output I notice ‘PSRAM = 0’. I tried reducing the circular buffer size to 10K as you suggested, but if any thing, this increases the frequency of reboots. I remember you mentioned a hack that I don’t think I have incorporated, so I will investigate this further. Almost there.
There is a new version that works with the Arduino IDE (I'm assuming that's what you are using) and some instructions on how to enable the circular buffer (which I recommend you do AFTER you have it working with a 10000 circular buffer set in the main.h).

Ralph where can I send you a pcb??
You want to send ME a PCB? Check out my ABOUT page in this channel, the email address is accessible if you click a button (but not from a phone, it doesn't work). We can then communicate.
Where have you been
Still here but moving house this week!
hay where are you hiding . i hope all is good with you
Nearly there, go the PC up and running in the workshop but not completed just yet.
@@RalphBacon bless you well your having fun by the sounds of it lol. good just nice to know your ok :) cool we'll look forwards to seeing you when your done :)
A merry bowl of petunias to you Ralph :-)
I quite like petunias, although I'm not clear on the significance of a bowl of them at this time of year but appreciated nonetheless!
Sorry @@RalphBacon, my Hitchhiker's Guide reference was way too obscure... but anyway, thank you for all the great videos. This novice has learned a great deal from them.
And I still don't know where my towel is. Oh well, Don't Panic.
Nice video SIr
So nice of you!
nICE
Thanks! Merry Christmas!
where are ya!!!!!!!!!!!!!!!!
Nearly there, Andy, nearly there!
Still no internet in your new house?
Connected two days ago but WiFi is terrible. No workshop yet, either. 🙄
@@RalphBacon Glad to hear you're still kicking, hope you get sorted eventually
@@RalphBacon as long as your all safe and well
Hi you ok ? It's been a while hope all is well .
Waiting to move house, Dave. Taking (a lot) longer than I thought due to delays with solicitors. land registry etc. Sigh.
@@RalphBacon well hope it all starts moving soon . I'm used to a Full English and it's not the same without Bacon ......
Nice of you to say, Dave. My (final?) eye op is tomorrow so that's a positive (for me) and means I can see my empty workshop better. Oh. Maybe not then.
*SCREW* *HOLIDAYS|!!!!!!!*
I know, they just get in the way of other stuff!

Yes, I know, it's been "mentioned" before! The good news is that the ISR frequency changes, from my calc of 3.829656, to 3.814697 Hz. We'll live with that.
Woow woow 😍💋 💝💖❤️
Merry Christmas!
Merry Christmas, Ralph, and a great happy new year 2021!
Happy holidays!
Merry Christmas and a Happy New Year
Same to you, Stig, see you next year!
Merry Christmas Ralph.
Happy new year!
