So after 3 months, I decided it was time to melt solder.The first step of assembly - the control circuitry - was completed in about 5 hours. This included about a half-hour of measuring all of the resistors with the DMM, taping them to the inside of the cardboard box, and penciling in their resistance values; color blindness sucks.
The Hakko 936-12 soldering station worked very well, but the Kester .020" solder I bought didn't flow - it just balled up on the end of the iron - because (I found out later) I bought 'No Flux' solder. I wondered why it was so cheap... I found some old, thicker Radio Shack solder that I had in the junk box and used it as carefully and sparingly as I could, mindful of numerous warnings about the hazards of using excessive amounts of solder. The PanaVise circuit board holder is the best thing since peanut butter, I can't believe I worked without one in the past.
The KX1 passed all tests at the end of Part 1 - all voltages were within spec, the unit powered up, the white LED lit, everything that was supposed to work seemed to work.
