Part 2 of my Halloween animatronic skull: servo easing for predator-like motion on a Raspberry Pi RP2040, and a 24 GHz radar that sees through plastic to track you. Code on GitHub.

An empty Halloween skull that turns to follow you round the room, with glowing eyes that redden as you get closer. No camera, no PIR. Part 1: how I built the eyes on a Raspberry Pi RP2040.

Event season hit hard this year. Maker Central, Evolve26, Hardware Pioneers… all incredible, all exhausting, and all packed with inspiration. Add in a wave of new Pico ecosystem releases, and July arrived before I even noticed.

I tried to let AI do the maths… it couldn’t. So I built a 3‑DoF Stewart Platform myself — and it works beautifully. Full story inside.

A new Droid project always means chaos — the good kind.

ReXP1, my Star‑Wars‑inspired droid, has been one of the most fun builds I’ve ever tackled — but one capability has driven me up the wall: tilt.

Saturday 14 March is, of course, Pi Day (3.14), and this year I’m doing something completely different on the livestream: a Live Build over on my channel. But this won’t be a Blue Peter–style “here’s one I made earlier” situation. It’s not even a rebuild of a project I’ve already done. This is going to be a start-with-an-idea-and-see-where-it-goes kind of day.
