Chu, yep that's pretty much it... the bulbs are 12V off a 15V so add a resistor divider on the back of each meter. (100k/470k works)And hey, thanks again for ignoring my request about what gfx/cad prog you use to make those diagrams. :)
aos, hmm damnit.. yea, same here... some are from sonic/tpc, some are from percy. Yea he takes awhile, but you do eventually get em... and if I learned anything from my stupid potentiometer adventure back in the beginning - this is not a hobby for the impatient. :)
Ben, yes. no. maybe. I dunno. It's a normal enough ss design, and I can alter it to be battery powered and drop the voltage and the current some, but kevin picked these components and values for a reason and I don't know how morphing it into a portable will work. Either way it probably won't compare to the AC version. I plan on ordering the parts though.
