Teen builds £30 chess timer with Raspberry Pi Pico W

Nirvaan Tandon started with Snap Circuits at four, learned programming at six, and encountered a Raspberry Pi at seven when he attended Coolest Projects, a showcase for young makers. Now 14, he's built a chess timer from a Raspberry Pi Pico W that's about the size of a king piece — compact enough to sit on the board between players, as described on the Raspberry Pi blog.
