=> ↺ This Open Hardware Li-Ion Charger Skips The TP4056
There’s a good chance that if you build something which includes the ability to top up a lithium-ion battery, it’s going to involve the incredibly common TP4056 charger IC. Now, there’s certainly nothing wrong with that. It’s a decent enough chip, and there are countless pre-made modules out there that make it extremely easy to implement. But if the chip shortage has taught us anything, it’s that alternatives are always good.
=> ↺ Lamptopus: The most adorable desk lamp in the world
If you have access to a 3D printer, this is a fun project that should be fairly easy to tackle. The light comes from two Adafruit NeoPixel rings and two servo motors provide the rotation. An Arduino Uno board controls those, with the sketch starting the rotation at set intervals. All of the 3D files and the sketch are on GitHub if you want to build your own Lamptopus, and Ruby Zoom’s video provides thorough instructions.
