Variable dc power supply

While tinkering with the BoxeeBox remote, read more here, I understood why you need a variable bench power supply. Other things I've been toying with have always been 5 volts, aka powered by my laptops USB ports. This circuit was powered by 3.3 volts so i needed a supply.

I went with, pretty much, the LM317 standard circuit from there spec sheet, link.

Mmm, spec sheet.

What three years of cg study looks like.

And it worked great on a breadboard, come time to solder it up I got frustrated when I tried to work out a layout so I just built it from input to output instead. So far The jump from breadboard to separate protoboard is a big one.

Doesn't look like much.

I'm quite pleased with the case and the front panel, I almost got all elements symmetrical and aligned

Complete variable bench supply

Parts where ordered from www.dx.com and most excellent www.electrokit.com

A few thoughts, the next one I build will probably have AC input, have a Amp meter and definitely have better binding posts, I still have to glue these down to the front.
