You can build a sci-fi inspired lantern using an Adafruit QT Py and LED Noodles. 3D print parts to build a container that showcases these flexible LED filaments.
Powered by the QT Py RP2040, six individual LED noodles are wired up to the GPIO pins and controlled with PWM.
It features a latching push button with a built-in LED ring for turning the lantern on and off. There’s also a print-in-place handle with a built-in hinge that allows it to swing back and forth.
It’s running off a cylindrical lipo battery so it’s portable and will last for several hours.
The USB port is accessible and can charge the battery with a Lipo Charger BFF add-on.
