What happened

A one-day workshop at the British Computer Society on July 2, the first day of the conference. The Circuit Playground MIDI Multi-Tool went to v1.0.0 on GitHub for it, with ten modes: capacitive touch to MIDI, light sensor, sound sensor, temperature, a cascade of random notes, accelerometer X/Y/Z, tap detection, playing incoming notes on the speaker, random notes with no MIDI at all, and RGB mixing on the NeoPixels from incoming messages. The slide switch and the two buttons change mode.

The projects page assigns a mode to each project and leaves one puzzle open: "Because we're limited to two 7-bit messages instead of a single 8-bit message there's a curious 'bug' with this approach... Can you identify it? Can you fix it?"

The site was deployed to GitHub Pages. The LibertyJS site a year later overwrote it at the same address, and both are offline now.
