The Digital Design Weekend at the V&A is great (still on, and free, tomorrow). Soil-powered microcontrollers, tactile synths with fabric, generating font glyphs with facial expressions, a very interesting physical model demonstrating LLM secret instructions and bias, augmented reality tales from the US/Mexican border, and drawing robots (the last being one reason we went over!). Lots of Pi and microcontroller and other #maker things of interest for all ages. Best museum in London by miles.
