"This is the first step of making a DIY (obviously) harmonic table MIDI controller. It is based on the midibox.org core module. For more info and other similar projects, visit http://synth-diy.blogspot.com"

MOTM-820 Assembly

snip:
"With all of the transistors in, this phase of assembly is complete and the board is ready to wash. In its kits, Synth Tech divides board stuffing and assembly into two phases: all of the parts that can tolerate water immersion are installed first, using an organic acid-based solder. This solder does a good job of removing oxidation from pins and board traces, but it must be washed after soldering to remove the acid flux. After the final wash, the remaining components are installed using a "no-clean" solder that doesn't have to be washed, but requires more care in soldering. The board, ready for wash"
