Velly nice!

I'll echo that one, too.


What do you use for a power supply?

That's my next project. G It needs to be a 700 mA current source
with load voltage circa 3 volts or so. Previous version was 350 mA so
an LM317 and sense resistor epoxied on the top of a wallwart sufficed.
Might work here too if I can find a 4.5 or 6 volt 700mA wallwart.
Else, maybe a little switcher.

Remember to spray paint this one poorly. It'll take the shine off it
so it doesn't disappear like the last one. You know how thieves are
when it comes to shiny baubles.
