PSU : prices and differences

[irving2008]

Guys, lets not start WW3, ok.

You both have valid points and all the info is out there including the thread I linked to. BUT none of this in the right form for a newbie to electronics at this level. What we need is a properly structured tutorial to help answer the question 'how do I build a linear PSU for x volts' with a 'best practice' design, a schematic and assembly guidelines along with photos of good - and, maybe, bad - examples.

I'm willing to have a stab at the words and there's a good working schematic that I drew in the thread I linked to.

What say you?

I'm ok with it. . . . All I'll suggest is that you keep the information has simple has possibly and keep technical jargon and complicated formulas to a minimum. They are not really needed in this case anyway.!!

Remember the target audience is new comers and they don't want rocket science maths just plane simple information, more than this and it complicates things and puts them off which really shouldn't need be the case for building such a simple thing.!

I agree Dean, and the drawings Jonathan did are useful too.

That would be greatly appreciated, i for one am Electrically Challenged and couldn't even contemplate a build without some assistance from you guys.

Fun fact #3: the actual voltage you get will depend on how far you are from the substation, further away will be lower, and will drop during ad breaks on tv :)

I shall be watching this with interest as I'll be wanting to make a power supply for my router and am not very electrically minded.

All I know is you can't smell it (unless after and there's that burning smell...) you can't see it and that if (when you're small) your toy train set doesn't work don't go testing your shiny new mains transformer like you used to with your 9V battery controlled one (to see if the batteries were on their way out) and lick the wires........
