Ep 387: Superhuman Clocks, CAN in USB-C, and the Joys of Bare Metal
Summary
Episode 387 of the Hackaday Podcast covers CircuitPython’s new pre-compiled function support for improved speed, a reverse engineering project that creates a C driver for a Bluetooth printer using the bleak library, and a comprehensive Rust-based firmware rewrite for an e-scooter. The hosts also discuss modeling CNC cabinets in CAD to prevent assembly errors and highlight intricate mechanical clocks, including a tumbling icosahedron timepiece and a frameless sliding puzzle clock. Additionally, they address a listener’s question about reverse engineering an aircraft clock and promote upcomin…
