Making music technology and electronics engineering genuinely accessible and affordable for young people in Hong Kong and beyond.
We design hands-on STEM kits and workshops that put real music technology in the hands of young people. Build a velocity-sensitive MIDI keyboard from cardboard and components, understand how it works, and take it home.
A growing set of interactive music tools that run entirely in your browser — no installs, no downloads, no account needed. Designed to work alongside the kit, or just for fun. Open them on any device and start making sound immediately.
The Leftover Tunes YouTube channel documents the whole thing — building the product, running workshops, and exploring music technology from the ground up. Honest, personality-led, and made for anyone who's ever been curious about how music actually works.
