The overlays could then be made of mylar (or other suitable film) on which the overlay could be printed and attached to the plexiglass. You forgot the 11/20, 11/45 (and it's ilk) and the 11/70. There are a few other devices that use it as well, I just don't remember them all at the moment. I'm working on that now. I'll include the exact parts list in a day or so, but this gives you the gist of it: * 2 0.01 disk caps * 1 330uf electrolytic * 4 ULN2308A transitor driver array * 1 SN7400N * 1 SN7406N * 28 330ohm 1/4 watt resistor * 5 1kohm 1/8 watt resistor * 3 SPDT toggle switches (I'll get the specific p/n as the board is designed for them to "just fit"). * 1 SPDT momentary switch (same family as above) * 28 5mm LEDs The ULN2308A and the switches are the only "interesting" parts. But I've made sure that the parts can be sourced from at least one of the usual places. -- TTFN - Guy
