DIY Mechanical Macro Numpad for $8

This video showcase my recent attempts to convert my previous macropad design that uses CH552G, into a full size numpad that features 17 (standard numpad) or 20 (macro-numpad) keys arrangement. The whole numpad can be built with just $8. The PCB itself cost the same as previous built, but the increase in cost are mostly came from the keycaps and switches.

The PCB and Arduino eco-system based firmware are open source on my Github. If you want to build one, you can take a look at the technical stuffs here:
