Printed circuit boards for Gate Grinder, a Kosmo format (not Eurorack) synth module. Can invert gates, change the lengths of gates, convert gates to triggers, convert triggers to gates, make a gate clock, make a trigger clock.
There are two PCBs, a main board and a panel components daughterboard. Third and fourth pictures show the built module assembled with a temporary wood front panel. This front panel isn't included nor are the components, this is just the PCBs. I'm getting a PCB front panel made and some of these should be available soon.
This was the first run of boards and there is one minor issue. The main board is too long. About 15 mm can and should be cut off the bottom, see photo. I can cut this off before sending if you want, or you can do it. Cutting wheel on a Dremel works fine.
I can provide the BOM for parts to build this module and some notes on the build.
The module design's been tested and works, although at the moment the output voltages are kind of low. This can be addressed by changing values of resistors in the output voltage divider; I haven't yet verified optimal values but it's a simple calculation.
