I made a basic Hack pad with 6 keys, 1 rotary encoder, 10 LEDs, and 1 OLED display. I would use it as an audio controller using the rotary encoder to control the audio output and the line of ten LEDs to show the audio output. And the key would be used to pause/play, fast-forward, rewind, mute, and more. The OLED display would show what's playing (via Spotify). I think this is a well-built hackpad, and I am very proud of it.
