🔴 Building a big button
Supplies to order
🔴Eaton FAK-R/KC11/I big red button (for ~37 € at Voelkner, goes for ~70 € elsewhere) – or 3D print it yourself! 📻Teensy 2.0 microcontroller 🔌Mini-USB to USB cable (as Teensy 2.0 uses Mini-USB) 🐍~10 cm of wire (to connect Teensy to switch)
- optional: Rubber feet (like 3M SJ5012) (for better stability)
- optional: Cable bushing (like 12mm EAN 2050000168062) (for nicer look)
- optional: Two component glue (to fix the USB cable to the cable bushing)
Tools you need
💻Computer to get the code onto the Teensy 🛠️Screwdriver to close the button casing
- optional: Soldering iron if you want to fix the connections properly
Steps to build
Install Arduino and Teensyduino on your computer. In the process you will connect the Teensy to your computer.
Connect the switch in the button (I used the green one) to the Teensy using wires like this – one wire to GND, the other to C7: (Optionally solder these connections. Based on wiring of The Button / Another Button.)
Optional: Put on the rubber feet and the cable bushing for nicer finish.
