Mobile Infinity-Hole

Just a small scale infinity object, which uses laser cutter, 3D printer, soldering and programming in a very easy way as a small scale workshop.

We use the laser cutter (for two circles of 3mm acrylic, 7cm diameter), a 3D printer (for the frame) and a WS2812 LED strip (60led/m, 13 leds) and a small microcontroller (https://www.instructables.com/StripNanite/ , but we are working on a better solution apart from making it DIY).

3D print the frame, and the laser cut the circles. Either use premade semi-transparent acrylic (expensive, but we had rests of it) or just clear acrylic and attach semi-transparent foil (for window darkening) later on. The controller will be soldered at the strip and inserted in the smal extension in the frame. It will secured with a drop of hot glue. The LED strip can be then glued inside the frame, and the Colorpalette demo of the FastLED library uploaded on the controller (with pin changed to 0, number of LEDs to 13 and brightness to 255). The mirrors should be then press fitted into the sides of the frame (with the foils to the inside for protection), otherwise use a bit of super glue.

Ready to enjoy :)
