Seeing the scope slip gave me a real "oh shit" moment. Even if it's not mine, a really old one and was most likely not hurt in the making of this video.
nope... I grabbed it out of frame. But it's really rubust.. you can see the plastic frame is broken on the right side. It's so heavy the old shelf indeed collapsed and the scope fell two feet on a wooden board. the probe connectors punched holes into the board but it still works :-)
Nice optimization ! Seems the ideal solution would be to segment the relevant library functions with the additional set up and teardown requirements under something like fastdac.h, leaving the standard calls so it would be a drop-in replacement library (or simply submitted to the ESP32 project directly). Thanks for the interesting video !
It's a nice idea... I'm a really lazy dude. Once a project like this is done I'm already busy doing the next one. At least I released the code public domain. Ivan could consider using some of the stuff according to the design strategy of the esp idf When I manage to create a team sometime the good stuff might end up in libraries which will be distributed by a dedicated server. This could simplify the life for many people
I got this to work on my Siglent Scope - its amazing work! I have a retro monitor and now I want to drive that - which ought to be easy enough - I'm guessing its been done many times.
That's how these scopes manage to be so cheap. Almost every major vendor is doing this. And not just scopes - power supplies (unlock 10x better precision) etc
Bangood is smart to sponser you and give you equipment its a very good channel and very educational, funny, and creative. I hope they sponsor more and give you lots of esp32 and rfm56hcw, lora, and the works to make videos with.
They are really happy with the result and asking for the next project. I have a quite long backlog of projects I like to do for a long time now. All the parts and equipment is here. Getting sponsored by hobby king would be nice. Can't afford the huge outrunners, batteries, and escs for an electric hoverbike.
Interesting optimization. If someone would use DAC for function generator what can be expected as maximum frequency (for sine and triangle wave not plain square wave)?
This is depending on how fine the resolution of the sine or triangle should be. the lower the frequency the smoother the curve. with the measured 7M samples you will get the best the 8bit dac can do at around 20kHz. at 1MHz you will get something that is shaped like that: -¯-_-
hi I like your all project. I programmming esp32 now. I need help AHD camera. I want display the ahd camera live (security camera) to web page .but ahd camera output NTSC system. I have to convert ntsc signal to webpage. Sorry may be i can mistake when i write! simply(AHD camera output cable--> ESP 32-->web page(etc. html )--> live video
Your every video is as excellent and as perfect and as creative as falcon heavy launch and landing. :) I have belled you finally .... looking forward for more falcons from you :).
Great to see your channel again and great work! But, I have the opposite goal to display complex RGB lissajous imagery onto an LCD HDMI screen, in order to preview images, prior to sending them to the laser projector(s). I've been searching the Internet for months and haven't found a solution, but have seen other laser controllers doing it. 🤷♂ Happy 2023!
Hi I am that guy with the cat comic on my oszi. Will your sketch also work on a analogue oszi? Or does it use the digital storage and sampling of the rigol?
Why is that Arduino Due has DAC within range of 1/6 to 5/6 of Vcc with 12bit resolution and cheaper ESP32 8bit DAC within range of 0-3.3V without any additional circuit.
They buffer the DAC with a non rail-to-rail opamp because for a given transistor footprint, you get much lower distortion if you sacrifice rail-to-rail capability. Biasing is fragile and crossover distortion is high in rail to rail opamps realised with the footprint they could have spared on a very dense mostly-digital IC.
the dac output has to run on one processor which is the majority of the processing. the vertex calculations could be done on the second core, but then it would require double buffering of the calculated vertices... this means half the amount of vertices are used now since the sketch with all the 3d models is at the memory limits. esp32 with the external spi ram could work
I tried doing this on my STM32F4 a couple of months ago. I got to a point where i could display 4 shades of green on my scope but after that i gave up because the IDE crashed every 5 minutes.
STM32F7 is pretty damn fast... i don't know how it compares to ESP32, difficult to say - official DMIPS figures say that ESP32 is a bit faster. STM32F4 though, naaaah, slow, no comparison at all.
the esp indeed runs at 240MHz the stm at 216Mhz. I even included the line to set the high speed frequency in the setup to be sure it does not change in later arduino plugin revisions. the stm seems to have some other nice features... like jpeg encoding, usb etc... the esp has two cores... not sure if there is an actual winner
Hey, I’m very new to your channel and I loved all the videos I haves watched so far, I was wondering if you can do a couple videos on the arduino module Rc522
very nice work >>>> can u make r2r dac by using shift register serial in 8 bit pls i realy need to know if it work and how write the code to show x y vector on Oscilloscope
Best unboxing ever!
I borrowed that scope off a friend in exchange for a bottle of wine -I fixed all my hardware issues so fast with it. It’s amazing for the price!
never seen such great "applications" for the XY mode - really fabulous!
Gotta love the 8-bit ducks!

@@bitluni So do you end up repairing and using the old scope (old scope is better as a novelty XY display)
3:46 why would you ground 2 probes if they have the same ground?
What a great project with a lot of very useful tips! Love it😂!

Wait you have to pay extra to use features even after buying the scope? That's ridiculous
Just watch the video again and mention the hint from bitluni about dave jones ;-)
That's how these scopes manage to be so cheap. Almost every major vendor is doing this. And not just scopes - power supplies (unlock 10x better precision) etc
That's how all software works these days
You can crack it as it work offline.
Lol it is an EAscope.
The extra features aren't mentioned on the spec sheet for the lower priced scopes. You get everything you pay for.
I liked the quickness of the quick unboxing... ;-)
I also liked the fast ducks... duck output enable... =)
I am trying to mimic a remote kefob. 40mhz Narrow FM. I wonder if DMA I2C could do this on a single esp32 pin?
that unboxing should be a meme
my sis thought this too and created that gif: media.giphy.com/media/3ohc0RHrD9tPHvb1qU/giphy.gif
Du bist ja mal der Hammer!!
Amazing for boring winter days : )
Will esp 32 camera output to composite video work with same idea?

This is the model I have, got mine direct from Rigol and at the time was the cheapest price. Is an excellent scope for a hobby guy like me. :)
Congratulations! That was a super majestic unboxing. GREAT!
Is this possible with 8266? Thanks.

EXCELLENT unbox! Bangood rocks.
If used as a binary output, is the DAC as fast as all the other GPIOs?
Your videos rock bitluni.
help, esp32 and pcm5102?
I am trying to implement image recognition. Do you think we can do it on esp32?
You are a genius
Your every video is as excellent and as perfect and as creative as falcon heavy launch and landing. :) I have belled you finally .... looking forward for more falcons from you :).
Keep up the good work man! These videos are great!
Would this optimization also speed up display? analogRead?
You need to implement the Z axis, brightness modulation, so you don't have to move the pixel off screen.
I don't think the SCOPE itself supports that (But let me know if I'm wrong!!)

PS: U only need to connect one of the ground-clamps, there are shorted together internaly
I just wanted to have the shortest current path possible... but you are right.. It probably won't make a difference
bitluni's lab Well faire enough, thank you dir the answer. Ps: Ich liebe deine Videos
Sowas von Thumbs up! Well done, fun to watch :)
Awesome video, I love your work. You're both fun and interesting to watch! Subscribed ✌️
Nice work , keep the good work
Great work again!!
sieht so cool aus
Süß wie du 😍

Great info material about DAC. Can i steal some part of code?
It's public domain... do whatever you like to it :-)
seems like the 15% discount on the Rigol doesn't work?
Just checked again.. Are you sure you have type it correctly? Measure
it should also work for other scopes and even some multimeters
That was awesome and fun.
Will there be a giveaway of the old analogue scope?
I tought about it, but it really weight's about 12kg, shipping costs would exceed the value of the scope
Selbstabholer-giveaway? :D
you could have used the second processor core of the ESP32 to improve the performance
the dac output has to run on one processor which is the majority of the processing. the vertex calculations could be done on the second core, but then it would require double buffering of the calculated vertices... this means half the amount of vertices are used now since the sketch with all the 3d models is at the memory limits. esp32 with the external spi ram could work

too bad, is it also using arduino ide?... arduino ide sucks ass, I hate it
@@bitluni what ide do you use?
hi! whats about stm32f4 or stm32f7? its more faster then esp32
And more expansive got my esp32 module(with FCC) for under 5 euros.
EDIT: Actually what do you mean with faster?
STM32F7 is pretty damn fast... i don't know how it compares to ESP32, difficult to say - official DMIPS figures say that ESP32 is a bit faster. STM32F4 though, naaaah, slow, no comparison at all.

Awesome in so many ways😂
Soooo... the regular Banggood price for the scope is 15€ more than at Conrad Elektronik, if the import duty is considered... nice!

I have an unreleased synth project doing this on the esp8266. I will update this and show it in the next months
You are genius.
hey how do people get sponsored components from online stores?
Tejas Arlimatti Having a popular online presence is usually enough.
There are youtubers who get sponsored components from popular companies like seed studio, etc who have hardly 1k or lesser subscribers.
very impressive!
So clever!
Instant sub; great video
Love it! I have the same scope. :)
i haven't understood anything u just explained.....but i like the video
thumbs up.....>>>>>^^^^
... as long you get curious and try to experiment yourself it is good enough :-D thanks

Right, there are other ways to get all features working... Nice Riglol scope.

Don't destroy your old oscilloscope some of us really need 1. Great video!!
I think it was illusion thru the magic of TV
you got me
красавчик, взял на коленках телек собрал.
😨 wowww !!!!! 👍
Cool
my teacher have this oscilloscope. but he don,t allow us use this one . he always give us other cheap scopes
Where is Astonia? I thought maybe she was at the door. She is cute.
Antonia will reappear in few weeks :-)
pay to unlock features on the scope...wow
imposing..
AERFGHHHHHHHHHHHHAHHH
