I'm looking ahead to some new lab work in my physics class and have found a
need for several adjustable 5volt power supplies. Were I to attempt to buy
them commercially, I'd be out my budget for the next decade (ok - a bit
exaggerated), but building them would be a cool project, especially if I
could get some perf boards pre done. Does anyone have a suggestion for a low
end 5v adjustable (down) power supply schematic? Cheap is an operative word
right now in the state of Washington. It would be much appreciated.
