Cherry ML Function stickI was left over with a lot of ML keycaps from the MLP keyboard. Created this thin 1x12 macropad for use as function keys.
The Pro Micro is running a simple Arduino sketch.
I built 2, one with 6mm spacers and one with 4mm spacers. To use 4mm spacers you need to use a low profile socket. The thin head laptop style screws are very low profile. I will be sticking these to the edges of monitors with 3M command strip removable adhesive.
The files are on Github.
