I'm really look forward to this , 1 I've always wanted to make my own power supply
2 The learning process of making a pcb
3 The whole learning process is good in so many ways
4 You can NEVER have enough power supplies.
You can probably tell ,I'm very excited about this series.
Well done Martin, let the journey begin

I also think this will make a great series, as I'm currently in the process of building power supplies. I was going to make a really simple one, and then a more complex one for higher voltage/current, but the simple one started to get more full featured and hence more complex.
Anyway, I'm still working on them and have experimented with various ideas using a variety of techniques for both voltage regulation and current limiting (LM317, LT3080, zener diode etc etc).
It will be interesting to see how Martin tackles it.

I think he will tackle it the way we would ,accept he's already made one, I have a couple of digital displays which I want to use , volts is Red, and amps is Green, plus a couple of meters as well, which will finally get used.

Me too !
And i hate some of those stupid reactions on Youtube ! Martin is doing an effort to explain something. look forword to see more vdeos so i can build one too.

I'm looking forward to this series, I know Martin video are long but I get so much more out of it.
I'm going to attempt to build one at the end of this series :)

Martin, I've been waiting for this series for a while. Can you please have a look at including CC and CV indicators as well. I've noticed your college supply has a CC indicator. Another nice to have would be course and fine adjustment for both voltage and current controls. I built a power supply a while back with course and fine adjustment but can only control voltage. I used a digital display I got from Franky that displays both V and A which can be powered from your output lines or a separate supply. The display is a bit on the small side but works for me. Please keep these vids coming.

Hi Folks,
Thanks...I look forward to this one too...it will be a journey as I can see a few challenges but we'll do the full Monty. I'll post all the relevant information so anyone can grab the info and build one. I'll start off by posting the circuit diagram and parts list of my college PSU once I have it as that has been a handy tool as is.
Cheers,
Martin.

I will have to dig out the one I made as an appy then........

Found a photo of the lift model I made. Working 3 story lift with manual doors.

Yes good I've haven't done any metal bashing before , this project is good in so many ways, I'm going to take my time, at every stage, and hope to get the casing powder coated, I'll also have a go at making a printed circuit board, so Martin, I'll have a few challenges on the way to, but guess what I'm looking forward to them. 8)

What course did you take Sean?
I've seen some working models of lifts and think they are brilliant.

As a preparation for Martin's power supply, i took my power supply from an old server apart. Was working, and i have a secund one, exactly the same.
Maybe i can use some components, i am not an enegineer, just a hobbyist. I was hoping to find a big transformer, but yeach :D Lots of inductors, or what are those ? But maybe i can use a capacitor, a rectifier, ....
Some pictures :
-
Lots and lots of inductors and common-mode chokes, a good bridge rectifier (although those are a dime a dozen anyway), and some seriously chunky rectifiers. There should be one or more pretty good MOSFETs in there. Not a lot which is relevant to a linear supply, though.
-
Martin, qualified instrument mechanic, both regular and avionics. Got the avionics first and the second as a getting retrenched bonus.
Edited because I cannot spell for some reason suddenly....... ;) must be the grey hairs.

Thanks Monkeh.
The cost doesn't matter. I know for 10 € you have a bucket with components.
Maybe is fun to use something from it. Like a heat sink or so, or that mosfet you were talking about.

I've just been reading an old book, Power Supply Projects by R. A. Penfold.
Its from about 1980 and seems to be out of print now (I got this on ebay), but it is quite informative and well written. Some bits are a little out dated, but not too much. It seems to be written from a hobbyist point of view which is excellent.
I highly recommend having a read if you can get a copy.
Penfold also has another book called More Advanced Power Supply Projects. It'd be cool to see this one as well, but I haven't been able to get my hands on a copy yet, as it also seems to be out of print.

Aaah...thanks for that Sean...can't be anything wrong with those grey hairs as there seems to be a fair amount of wisdom behind them.
Just been reading some of your input on precision voltage references on EEVblog...very handy info...thanks!
