Gathering weather telemetry with a Nano 33 BLE Sense payload
Reading Time: 2 minutesMost model rockets don’t do anything practical — they just go up really fast and then come back down more slowly to land in a field somewhere. Those launches can still be a lot of fun to watch, but they aren’t exactly useful. However, the sky has plenty of data of worth…

Flexible PCB watch
Reading Time: < 1 minuteThe first of these was the choice of microcontroller; although he used a Raspberry Pi Pico in the prototyping stage, the RP2040 was just too big to incorporate in the final build, so he used the snappily named STM 32 UO0 83KCU6 instead. The other big challenge is that at full…

German word clock
Reading Time: < 1 minuteWe’ve seen word clocks before in several configurations, including laser-cut, 3D-printed, and one intriguing version that used servos to bring the projected words in and out of focus, rather than revealing them through a grid like usual. However – and this is strange, given that we live in a big, varied…
