Presentation

This infinity mirror works with an Arduino Nano or a clone. I added an external control to adjust the colors, trigger the rainbow effect, and turn it on or off. The design is quite sleek, with invisible screws if printed in black.

Instructions

The design is fairly simple. I used 5V LEDs, with 6 LEDs per side for a total of 24 LEDs, all controlled by an Arduino Nano, housed in its own hidden compartment.

Mirror Parts

To make it work, you should use a full mirror for the back and a tinted glass for the front. I applied the tinted film myself, but it was a rather tricky process, with a lot of trial and error to get a perfect, bubble-free layer. If you can find a pre-tinted glass, I highly recommend going for it!

I glued the back mirror in place. I had the back mirror cut to 198 x 198 x 3 mm at my local hardware store, and the front glass to 209 x 209 x 3 mm.

Electronics

There is one crucial point: solder the 5V LED pin directly to the 5V power supply. Do not use an Arduino output, as it cannot provide enough power for the LEDs to shine as brightly as they should.

Printing

The print uses the entire bed of my P1S, so it couldn’t be printed on an A1 Mini. Supports are needed for the Arduino compartment. I used M2 inserts for all the screws, which gives it a very clean look. There is a hole to pass the LED wires from the Arduino compartment to the inside of the frame.
