Macro Keyboard

Summary

I saw this great tutorial online with simple instructions on how to build your own macro keyboard. Best part was that the electronics/soldering side of things was so simple that it served as a great primer into the world of electronics and everything that underpins the code I write every day.

My local library has a 3d printer that I use quite often (a Tiertime UP300) which took care of the enclosure, which meant I just needed to order the cherry switches, keycaps and Arduino Leonardo board. I ended up with a “Duinotech Leonardo Tiny” which served the purpose fine but only had room for 6 keys (whereas the enclosure was built to accommodate 8). Soldering the headers onto the board and daisychaining the switch terminals together was heaps of fun.

I really wanted to make Teams calls easier to manage so I’ve chosen the following key configuration:

• Vol +
• Vol -
• Mic toggle
• Camera toggle
• End call
• Bonus button!
  • Couldn’t resist turning my last key into a “show me cute photos of my daughter” button. It brings up a full screen carousel of my favourite photos from my Google Photos library.
