I was testing the fab’s ability to handle plated slots and ended with what looks like a pretty useful tool to convert 1.4″ connections to 3.5mm and back. Instead of maintaining a bunch of mixed jack conversion cables I can now just run standard ones through this tool.

MidiALF/CV board Rev 0.2

Here’s the second revision of MidiALF/CV board, streamlined and improved.

Schematics: alf_cv#1 alf_cv#2

Edit: Gate3/4 connectors were moved to the top of the PCB. The plan is to use taller stand offs on the back side so that these connectors fit in with the MIDI I/O connectors.
