Comments I'm told really helps this channel, and if we can do something small like this and it makes a difference I'm 100% in support of it. Paul's the best
This channel is one of the best resources I've found for understanding how to create actual working circuits for anyone who is learning. Thank you for taking the time to create these videos.
Paul is great! Experienced pro's can learn from him. He covers things that any electronics junkie needs to know on both circuits or equipment. Time very well spent on this channel!
Thank you for SO many things - sharing your experiences (both the good and the bad), your knowledge, your humor, your time, and your Gerbers! I appreciate it.
I realized I've been enjoying your teaching style and content for months now. You have a natural talent for instructional videos. You're doing a great job.
This is a comment, as requested. Thanks for the amazing videos, this is the first place I check when I need some info for projects! GL on 100k before the end of the year, you got this!
2 weeks ago I came for a multimeter review. Then I saw a movie in which you advise young Erik how to start his adventure with electronics cheaply. At this point, I knew I was in good company and the time spent on your channel is well worth it. P.S I subscribe :-)
The kids are grown and no longer a distraction (Trying to eat parts or play with the soldering iron.). Wife is gone so there's no one around to tell me that I'm "wasting money," or complain about "messes." The remaining pets are older and more civilized. They tend to doze quietly in a corner now. Interesting parts from China are so cheap and easy to use. I think I can finally finish the robot I've been building for 50 years. You're an inspiration. Thanks. OBTW, while metric units of measure are better in just about every other way, (with apologies to the rest of the world,) when working with parts that came out of the '70s digital era--sometimes it's easier to use imperial units of measure. It's just that ".1 inch" is so much more elegant than 2.54mm.
Thank you for your excellent projects and videos; your experience and imagination is a great asset. Keep up the great work; from Phil over the pond in the UK.
Your videos are so helpful. As soon as I see there is a new one I watch it. I am learning so much about electronics that it has come to extensively augment my model railroading hobby. Thanks for your contributions!
Such a good boy, helping your aunt and mom. Nice pcb, I have started getting used to surface mount parts. The biggest reason is I now have a good microscope for soldering a Swift S41-20. That even helps my 56 year old eyes to see those tiny parts.
Howdy from San Francisco! I'm a big fan of the 317s. I restore old test equipment and one of my usual tricks when rebuilding VTVMs is to build a small battery eliminator powered off the filament voltage; then you never have to worry about leaky batteries ever again. I build my circuits with a 1k trimmer so I can bring the voltage right to 1.5V (or for my oldest models 3V) It's not really needed but I'll stick on one of those small heatsinks just to be safe.
Really cool. A couple months ago I knew squat about anything, now I actually followed along and understood everything! Great instructional videos, thanks Paul.
If you draw any significant current those regulators are going to overheat very quickly. You may need heat sinks. Plus what also helps is to put a big diode inline with the power supply. This will help drop some of the voltage across it and provide reverse polarity protection.
EXPERIMENT COMPLETED!! I hear ya on this friggin heat!! Here in MI today, on my local weather app, I'm told the temp = 92°, & feels like 99°!!! We're cookin' now baby! Whew!! BTW - the sound of the running AC is/was minimal, and not intrusive at all. Also, thank you SOOOO much, kind sir, on all the videos you make. When I see them pop up in my feed, I save them into my own little custom-made saved folder, titled "LearnElectronics", then watch them every weekday, while drinking my lunch ;) Thanks again, & please keep it up!! "Peace - I'm out." :D
I have a couple of the Elegoo power gizmos. The problem I find with them is they take too much of the board up and if you move them out further they like to tip down and come unplugged. I hope everyone weathered the storm OK. Thanks for the video!
I hope your mom and auntie are ok. I have two of these I bought one from eBay and a friend give me one. I definitely will look into building one I like doing little project like this. I might do it slightly different where everything is surface mounted.
Great video, I have about 15 of these otherwise I would build my own. Be nice to add a small RGB LED on each side that shows either yellow for 3.3v or red for 5v (or whatever colour you choose). That way you know at a glance what voltage it's set at. I like boards neat also and having components lined up just looks more professional. Its different for a first time test on a perf board but even then if it's neat it's easy to see what's what. Nice video mate, keep them coming. I hate surface mount also, have lost a few fingers so it is just hard screwing with small surface mount crap.
lol... hello, focus... and the 3.12,12,12 volts... excellent video... as always... great channel you have here... very educational... anybody see a breadboard file?... lol... and yes we hear the storm...
Just starting out like I have mentioned previously so I will watch it again so I will watch I again till I grasp it which I will. Thank you for sharing 😀😀😀
If you are doing a comment test, I made three comments, in a row, but I only see two of them. The one that is missing is the one that I said you need big smoothing caps on the input side of the v reg and you responded that you built it per the data sheet. I just learned about this very thing. Smoothing caps are considered general engineering and are not included in the data sheet, because the manufacturer can not know what load you will be putting on the circuit. But, they are always required (by the demands of the circuit.) They limit input ripple and maintain the voltage headroom/dropout zone. When the demand is unknown, some folks default to around 500uF. I default to 1000uF, just 'cause.
Hey Paul, I found your channel when i was starting to get into electronics and self teaching. its been an absolute goldmine ever since then, keep up the great work!! I was wondering if you could direct me to some more thorough teachings, ive been seriously considering going to college for electrical engineering but im on the ledge about that or going to a union type to learn hvac and appliance repair. i love to tinker/build/destroy/reverse engineer/ and love to learn. Im making myself a soldering station at the moment(waiting on parts!). so id like to persue some sort of education and job that would pertain to things of that nature. anyone else reading feel free to answer also! Thanks again Paul for all the education and inspiration you've already givin me!
Enjoying the Vids Paul. I like seeing you building stuff. Using boards thru PCBway seems a lot cleaner than old school dead-bug construction. Keep up the good work. 73 OM
There is an advantage to using the bigger through hole v regs over the smd type... They can supply considerably more current... The smds are 100mA, IIRC, verses the 1-1.5A of the through hole type. A breadboard project with a small motor, or two, can easily need more than 100mA.
Hi Paul, thanks for the video, I always learn something when I watch your videos. My personal policy is to always write a comment of a video I watch, in recognition of the effort that a TH-camr has made to give me free education or entertainment. You don't need to reply, just know that it's my way of showing support.
Those YWRobot power supply boards are great. I have used them for a few projects around the house. I had one that died on me. I may make some using your gerber for the heck of it, that way I could repair it. I am trying to make/design a PCB for a simple solar powered weather station but that EasyEDA program is a bit daunting.
Awesome. Exactly what I was looking for. thank you. To be honest, I'd love to buy this as a kit from you. I'd do the labor. Need practice anyway, its been a while since I did any pro level soldering. Oh, and who really needs prompting to comment? Always good stuff.
Hi, just watching your video and adding a comment. It was waiting in my watch later list as i had other priorities. However happy to watch this Interesting video now.
very helpful overview of the process. i definitely learned some valuable details. however i couldn't help noticing that your physical length measurement at 4:15 seems rather sketchy. you quote a distance as 39 mm - when you are noting the distance between the EDGE OF THE RULER and the 39 mm mark rather than noting the distance between the 00 mm mark and the 39 mm mark. could this have something to do with the troubles you mention at 5:24 ?

..you're the greatest Paul! ..I'm an old(er) electronics hobbyist (73) and love the ideas and tech know how that you give us! ..thank you Paul!
I realize this a commercial for pcbway ,but it is much easier and cost effective to buy them for a dollar on Aliexpress.
Thank you for SO many things - sharing your experiences (both the good and the bad), your knowledge, your humor, your time, and your Gerbers! I appreciate it.

Please include on the "all the gear I currently use" list the circuit design and Gerber file generating software. Thanks.

Thanks for this channel. I not only learn about electronics and components, but I learn how to think through electronic issues. Thanks again.
Love your videos. Especially that you don't edit out mistakes but how to fix them!
I like it written on paper so you can save it without electricity. You learn both ways.
More power to you; no resistence from me ! Your capacity for instructionals is super.
Hi from the UK I love this channel, I’ve just started doing electronics as a hobby. Keep up your good work

Great personal spin on a BB power supply! Those were some crazy storms and hope the flooding wasn't too bad in the aunties basement.
I love your videos and how you make little comments to the audience it’s always great to watch and learn
You're the best Paul! Always enjoy watching your videos.
Recently rediscovered electronics and your channel. Have learned much already. Thank you!

Thank You, It would be great if Cyber City Circuits picked this up and sent it out as a monthly kit

A great project. Thanks for making the Gerber's available to us. Appreciate your hard work.
Thanks, I learn a lot from your videos. Getting back into this hobby for my grandchildren. Who said you can’t teach an old guy new tricks!
Hi Paul, enjoying your video's, trying to binge watch from 2016. Keep up the great work.

Cool vid, loving this series
Thanks Paul for the continuous enthusiasm!
I watch all your vids and look forward to seeing them each week
Really like this channel. Helps me get into those nitty-gritty details of circuits.
Thanks
your one of my favorite channels ,keep up the good work man
Nice! If I was just starting out in electronics again, I think I would just use a 7805 directly instead of a breadboard power supply.
Love your channel. Always fun to watch and I always learn something. Thanks.
lol... hello, focus... and the 3.12,12,12 volts... excellent video... as always... great channel you have here... very educational... anybody see a breadboard file?... lol... and yes we hear the storm...
The sound from the air conditioner really isn't disruptive to the video. If you didn't mention it I would not have noticed. Great video as always.
You rock paul! Always willing to help with an experiment!
Hi Paul, I'm writing this comment because I 'm unable to when I watch youtube videos using Roku on the TV.
I enjoy watching and learning.
Take Care
late to the party, but discovered your channel recently, and I love it! thanks for the projects and teachings. Good Job!
Thanks for all your projects and knowledge, Paul! You have one of the best channels!
Exactly my next project. Cheers dude. Keep safe.
Good job Paul. By the way. You could use the LD1117V33-DG as it is a standard TO-220 , fixed output instead of the LM-317.
Your videos are so helpful, I really appreciate the video tutorials and projects.
Keep up the good work. Your videos are always clear interesting.
Thank you for your excellent projects and videos; your experience and imagination is excellent; from Phil, over the pond, in the U.K.
Just starting out like I have mentioned previously so I will watch it again so I will watch I again till I grasp it which I will. Thank you for sharing 😀😀😀
Nice work and nice channel, hope to see more about in circuit sound sensors. All the best
Thank you.
Always enjoy and learn from your channel! Thanks for sharing! Cheers!
Hmmm, @9:17 you substituted a 100pF capacitor for the 0.1uF capacitor... (0.1uF is actually 100nF and NOT 100pF)
If you are doing a comment test, I made three comments, in a row, but I only see two of them. The one that is missing is the one that I said you need big smoothing caps on the input side of the v reg and you responded that you built it per the data sheet. I just learned about this very thing.

One of the best channels to get some interesting ideas from
Great video as always. Hope things got resolved for your Mum and Aunt.
Hey Paul, I found your channel when i was starting to get into electronics and self teaching. its been an absolute goldmine ever since then, keep up the great work!!

Jon go for as much education as possible and I wish you the best in your endeavors!
Paul, your videos are the best
Your finished projects always look professional!
Thanks for taking the time to post these great videos.
94Deg - WOW, I so wish the UK would get that warm. But then if the rain stopped for long enough then it may well heat up.
Keep up the good work, thank you for all your work on these videos.
Just found this channel and I'm excited to watch more.
awesome ideas and work done on this channel, as usual! keep at er Paul!
Hi Paul, hope all is well. I’m watching all your videos as usual. 👍
Glad to see you survived the weather. Surprised you didn't use a trim pot. If you can't be precise, make is variable ... :-}
I'm Going to build a few of these...Paul your great
Enjoying the Vids Paul. I like seeing you building stuff. Using boards thru PCBway seems a lot cleaner than old school dead-bug construction. Keep up the good work.

A committed comment, as kindly requested... I guess it wouldn't be a big problem to adapt the design and add a third output for a variable voltage.
I have only recently found your channel. Loving the content.
We had a pretty good storm here yesterday afternoon too in Toronto - the original Canadian one... Take care Paul!
So sorry to hear about your aunt and mom. Hopefully there houses will be alright
I always enjoy your videos! Keep it up Paul! 👏🏻👍
Excellent topic for a video, you have encouraged me to make a couple of these too.
I love experiments! Keep up the great work.
Hi, love your videos, I dont watch al your videos, but quite a few.. Keep up the good work, thanks..
Hi paul, takecare n be safe. Also thanks for the contents, ❤️❤️❤️

I just realized I'm a Patreon supporter but wasn't subscribed. I've fixed that now :) Thanks for all the learnin'.
Thank you for this. Looking forward to the rest of the project.
Like the bread board power supplies, very handy...
Nice video, always learning stuff on your channel. Thank you!

Here's a comment - enjoy your videos - keep up the good work!
I enjoy your videos and have learned quite a bit.
Per request, a comment from Belgium. Thanks for all the vids and keeping content creating real!
Awesome. Exactly what I was looking for. thank you. To be honest, I'd love to buy this as a kit from you. I'd do the labor. Need practice anyway, its been a while since I did any pro level soldering. Oh, and who really needs prompting to comment? Always good stuff.
Brilliant project and ver useful... Thank you for your videos
Thanks for all the lessons!
Great little project. Thanks!
4:15 - I don't think you measured from zero when measuring the inside pins.
I didn't and had to adjust for that later
@@learnelectronics Are they correct on PCB way now? Thanks
@@learnelectronics When will it be uploaded on PCBWAY ??????
Noticed this too, glad he re-measured.
Commenting as requested.
Have the video on while laying out TP4056 boards on some plywood to charge up some lipo cells.
Hi, just watching your video and adding a comment.
It was waiting in my watch later list as i had other priorities. However happy to watch this Interesting video now.
very helpful overview of the process.
i definitely learned some valuable details.
however i couldn't help noticing that your physical length measurement at 4:15 seems rather sketchy.
you quote a distance as 39 mm -
when you are noting the distance between the EDGE OF THE RULER and the 39 mm mark
rather than noting the distance between the 00 mm mark and the 39 mm mark.
could this have something to do with the troubles you mention at 5:24 ?
