Feedback on power supply 0-30V 0-4A
d4n13l:
yep, I'm sure I screwed up somewhere in the wiring, I got an output range of about 3V on the upper end. I'm also a bit concern about the amount of current the stripboard can handle, apparently it may be somewhat higher that the ~1A I need but I'd like some confirmation.

I don't think you should have any problem with just 1 amp .But you can always double up the wire where most of the current travels. That would be the main ground plain and main positive plain.from rectifier to output.
I usual just check continuity between connections.This finds bad solder joints and solder shorts.If you tin the entire solder strip that also helps.A little extra flux won't hurt either.Just make sure that you clean the board well after soldering is complete.Sometimes just a tiny piece of dirt or carbon can cause problems..Another tip is to make a hard copy of the schematic so you can check off each connection as you weld it.

The biggest capacitor seems to be on the right side and not next to the bridge rectifier. Is it normal ?
May be you swapped some components ? It's easy to make mistakes :(
d4n13l:
Hi ggchab,
What happened there is that I have a bridge rectifier that doesn't fit the holes in the stripboard as you can see in the picture.

Anyway.. I finilly had time to try again and works great, the only problem is with the volt/amp meter that apparently I can't connect anywhere without messing up the current regulation in the circuit, I guess I'll just power it from a different source.
Thanks for the help
