Benchtop PS build woes.

[TheSniper]

Sam, this is an interesting project, but i am inclided to agree with others about the dangers of trying to build a one-size-fits-all solution. A supply capable of delivereing tens of amps won't be easily and safely controllable down at hundreds of milliamps, I'd suggest
Do you need control of the current, voltage, or both?
And be careful! Just because it's 12/24V, doesn't mean it's "safe", if there are tens of amps behind it. I once saw a telecoms engineer weld himslef to a piece of equipment with exposed 48V power supply bus bars, with his metal watch strap... which he shouldn't have been wearing, of course.

LW,
Although it would be a plus. the on the lower end of the scale. if it stopped at 1.0 or heck even up to 4.5 at it lowest setting I could live with that.
Voltage and current need to both be adjustable.
I hear you on the safety factor. and appreciate the reminder , BUT. theirs more everyday things that'll probably get me first.!
