That was 2025!

2025 was the year I actually shipped hardware: the ESP32 Rainbow—a modern, full-color riff on the Sinclair Spectrum—crowdfunded, certified, manufactured, and in customers' hands. The economics were brutal (COGS, tariffs, shipping, CE/UKCA), but the community made it worth it. I also went deep on high voltage, made a 10¢ MCU sing and talk, escaped printf hell with USB/JTAG, built a browser serial plotter, fixed broken gadgets, and even let AI pick parts. For 2026: more ESP32 mischief, more joyful builds, and probably more bodge wires than I'd like to admit.
