MicroMacro Mechanical Keyboard

The MicroMacro is a 1% (1 key) mechanical keyboard based off a cheap ATTiny85 microcontroller, complete with an arduino profile you can configure so it prints whatever you want!

I originally bought some of these to prototype a modular keyboard system, but made a pit stop to make a 1% keyboard.

the current software for the keyboard is here. It is based off the digispark DigiKeyboard library for now, but my dream would be to pare down the tmk_firmware to fit on an ATTiny so that any custom keyboards I make can be on the same software.

this might be a 1% keyboard, but I couldn't resist adding in an extra little feature: the SCAD file can support an arbitrary number of switches, all you have to do is increase the width and change the switch_hole_iterations! you can turn this off by setting switch_hole_iterations to 0. Please note the software does not currently support this, though adding such support won't be very difficult. Unfortunately with the current controller you can only fit two keys without having to do some extra work (soldering in a resistor or updating the firmware) but that means it's a perfect build for Osu! and similar
