In this project, I made an infinity mirror based on a dodecahedron that reacts to sound.

Essential materials:

Arduino Uno
3mm thick 100x50cm MDF
2mm thick 100x50cm plexiglass
3 meter WS2812B LEDstrip 60 LEDs/m
Sound Detection Sensor Module 3-PIN
Thin electric wire (10ish meter total)
Breadboard
Perfboard/stripboard
Simple rectangular rocker switch
Wall plug to 5V 8A adapter
220Ω resistor
1 m^2 one-way mirror film (enough to cover the plexiglass pentagons)
470uF 16V capacitor
Optional materials:

Spray paint
Tools:

Soldering tools
Somewhere to laser-cut (you could probably figure saw it with a lot of patience, but laser-cutting is advised)
Multimeter
Soap and water
Small window wiper
Scissors
Hobby knife/Stanley knife
Ruler
Clear glue (or any strong glue you prefer)
Insulation tape”
