This huge magic mirror is powered by a 7″ Raspberry Pi Touch Display. Raspberry Pi shared this video on Youtube!

We wanted a big project for the lobby at Pi Towers: something large and visually impactful. Our Maker in Residence Toby Roberts was inspired by Alex’s (aka SuperMakeSomething) NeoPixel LED mirror, and wanted to do something similar but with a blingy twist. He thought designing something that requires 576 glass crystals was the way to go.

It’s a 24 × 24 grid of NeoPixels, each with one crystal stuck in front of it. The NeoPixels are in an array configuration so they can be individually addressed to do all sorts of fun things. Like the project that inspired it, it can work as an LED mirror, and these functions are controlled by a 7″ Raspberry Pi Touch Display, which shares an enclosure with the power supply on the back of the frame.

It’s a hefty build. The whole thing including the frame weighs about 70kg, because each of the 576 crystals is real glass. That’s as much as many adult humans. Toby spent an entire day blunting the pointy end of each individual crystal with a bench sander so he could fix them to the LED board’s flat surface. He was quite patient about it, but will not be planning any more 576-crystal builds in the near future.
