Recent collaborations in other projects §

• Jonathan Pallant has an Open Source Project called Neotron, which consists of a retro-style computer. Its latest incarnation is based on a Raspberry Pi Pico (RP2040). He developed his own BMC, BIOS, operating system and user land applications. Thanks to the support of the Rust Foundation, he was able to send a few kits to selected “beta testers”, one of those being me. I have so far contributed the PC speaker driver code to the project (BMC + BIOS) and hope to contribute more.

Archived §

• PySecretHandshake - a pure Python implementation of the Secret Handshake key exchange by Dominc Tarr. This protocol underlies the Secret Scuttlebutt decentralized social network. I wrote this implementation back in 2017 and people still ping me about it every now and then. It has since been picked back up by Gergely Polonkai, who is maintaining a fork of it.
• Temperature/humidity sensor
