Homebrew PCBs

Mike,

Just single layer, single-sided. Three boards per kit.  One is 4x6 
inches (main curve tracer board). Two are 2.25x6 inches (power 
amplifier and power supply boards). There's also a very small fourth 
board, 1.25x0.75 inches, for a small 8-pin transistor socket that 
protrudes from the front panel (a third convenient redundant device-
under-test interface).

I have had to keep the boards as simple to fabricate as possible, 
since I also offer a lower-cost version of the kit that includes a 
make-your-own-boards option, with blank pcbs and toner patterns 
included (as well as powdered etchant, plastic etching tub, 
scotchbrite pad, aluminum solvent pan, etc).  (And, amazingly, even 
though none of the buyers that I know of had ever made a PCB with TT, 
before, only one guy out of 100 needs a new toner pattern sheet.)

Regarding a three-days-dead horse: Ever been to the Death Valley 
museum, at Furnace Creek, CA?  Excellent counter-example.
