I think this should make an excellent uSupply case - Dave Tweeted

Hi Dave,

I can't really get a feel for scale. What are the dimensions?

More generally, are you planning on doing more power supply design videos?

I am new to electronics and have been working through understanding these power supply schematics. I have learned so much from the videos/process of watching you design. I actually built up the supply from your 3rd video and was following along at home. That was the first reasonable sized electronics thing that I ever built up.

Anyway, I have heard you express dismay at the responses you have been getting from people on these videos. I guess there is a lot of backseat engineering going on. So, I just wanted to let you know that for me they were hugely beneficial and I really appreciate all the awesome videos. I completely understand if you don't want to go through the endeavor of producing design videos 'real-time' again but if you do I know that at least I would be grateful.

Hope things are going well!

I don't use twitter.  But I agree it was a great case for a uSupply and a uLoad.  Well it looks just like the ones I used, and I had just enough room. 
Using the uLoads have been very useful for power supply testing.  Much more convenient than regulator and resistor combos. 
I call them uLoads because each is limited to 28watts, 40v or 1.5A.  They can take more but I don't want to worry about the load when working on the supply.  They are not a real bench load but i use these to check for load imbalance problems.  I don't have the money to buy several bench loads for this.

Might as well watch this one to. Probably Daves most successful project.

Doesn't time fly

Never seen this video before. Cute.

That project has been under development for yeeeeaaars.

Don't start that again. Have you forgotten what happened last time?
Next we'll go on an on about knobs, displays and everything else that led to you packing it in for a few years.

It may sound silly to spin one's wheels over knobs and such, but until you try to design as awesome product you don't realize how much effort may be behind every single component, knob and switch. I've experience this myself; I spent a whole day deciding on a single inductor for a recent project--and I am still not completely happy with my choice.

Anyhow--I've found Dave's tradeoffs to be very instructional, and in the end, I don't mind that the project went unfinished.

He probably should have completed the project and then released the videos of his process. You see this all the time in projects that start in the forum, to many people start to chime in and it never gets done.

Just a hobbyist and non-native in English myself.

In my case,  if too many people chimes in, I am still who decides.

It could be that those so many differently oriented pieces of advice  could put me in doubt enough to stop undecided (happened/happens), but a seasoned engineer as I asume Dave is...come on, he can make a decision.

For several reasons, up to now, I ve watched in full just one of his videos and I doubt I would do again.

Just by peeking in the successive chapters, when I saw where he was going to, I realized it was totally different from what I wanted to do.

Maybe the KISS principle resulted some what neglected? Friendly and rethoric question.

Yes, I agree details are important. My point was mainly about that Dave got sick of the deluge of "suggestions" about his pet project and jacked it in. He commented as much on at least one episode of the Amphour.

Not quite right.
I never dropped the project, a technical issue came up which meant a possible redesign, and I simply lost interest for a while, like I have done numerous times before. I had already been through 3 or 4 major revisions of the uSupply before I even started shooing those series of videos.
Yes, I got sick of all the endless comments, but that wasn't the reason I dropped the project for all that time.
It is however a reason why I may not do such a thing again, designing something and producing the videos as I go.

I was a latecommer to the AH so there may have been more. It appears unimportant that he "invited" such suggestions by broadcasting his design and thoughts to an audience full of engineers.

Yes, I did invite such comments, and the series of videos was an experiment that turned out to be not as enjoyable as I thought it might be, due to the massive deluge of comments, some of them not very nice. Not just technically, but personally.
I don't regret doing them, I did enjoy making them, but it's something I would think twice about doing again.

But as he told me in another recent thread. It is HIS pet project.

Bingo. I added the features I wanted and did the things I wanted to, nothing more, nothing less.
And that was part of the problem, because there was no plan, I juts had fun bumming about thowing features in an out etc because that's what I enjoyed doing. Unfortunately many people didn't understand why I was doing what I did. They thought this was going to be a professional well thought out step-by-step guide to developing a product from start to finish. That was never the intent.
Designing a pet project like this is nothing like I would do if I was designing it professionally for a company or client.

Not that I am a electronics designer but I wanted knobs with plenty of finger room.

You are welcome to design your own!

Yep, that was my lesson learned from this.
Just throwing your random thoughts out there doesn't work well.

I have one of those projects! 11 years of development and still going on! Impressive is the fact that it keeps time (and money) consuming year after year, but the results are amazing! Mine recently developed the ability to take some beer out of the fridge for me only by voice command!     

Nice video, Dave!

Let me just jump on the occasion to just thank you, Dave, for these videos.

I am a software engineer and have been a electronic hobbyist for 2 years now (a young player you would say). I had no electronics background before trying an arduino starter kit, and I learnt a lot through the uSupply video serie. I am now trying to design and build a "similar" power supply, just to learn a bit more. It's a project I never intended to do in the first time, being (at first) more interested in using ready to use modules for arduinos in order to make quick projects.

Anyway, for my part, I wish there were more of these design videos with gotchas and traps explained.

I am grateful for the videos and the choice of open design, thanks.
