Hacker HotKey

This repos contains example software for the Kernelcon 2021 Hack Live! badge - the Hacker HotKey.

Default Keys:

Compiling and uploading firmware

1. connect micro USB cable
   • needs to be a data cable, not just a charging/power cable
2. open aduino IDE
   • install if necessary
     • https://www.arduino.cc/en/Guide
   • install keyboard library if necessary:
     • tools -> Manage Libraries -> search "keyboard" -> install

    arduino hackerHotKey.ino

3. select "Arduino Leonardo" board type
   • install Arduino boards if necessary:
     • tools -> Boards Manager -> search "Arduino AVR Boards" -> install
4. select com port
   • tools -> port
5. Verify port comms work
   • tools -> "Get Board Info"
   • should return something like

     BN: Arduino Leonardo
     VID: 0x2341
     PID: 0x8036
     SN: Upload any sketch to obtain it

6. choose your code
   • hacker hotkey sample
     • A simple firmware example that is a good starting point for developing your own code
   • hacker hotkey advanced
     • More advanced firmware if you just want to create powerful hotkeys without coding
     • Refer to the Hacker Hotkey Advanced guide for configuring hotkeys
7. upload code
   • sketch -> upload
   • Arduino IDE will compile and upload firmware to the Hacker Hotkey, which you can use immediately after upload (no unplugging, reseting, etc required)

3D Printing a case

We've designed a case for Hacker Hotkey, and while not necessary to function it does complete the look. Download the STL at Thingiverse
