I love some of the new wearable stuff that's showing up on Adafruit, Hackaday and Make Magazine. When I saw Adafruit's new 60 LED Neopixel Ring, I knew exactly what I wanted to build for my daughters... I had made a previous attempt at head wear for the Father-Daughter dance last month but out of failure comes inspiration.
Presenting the Laser Crown for the princesses in your life!
The Laser Crown is stunningly bright, lightweight and comfortable. It has no visible wires, USB chargeable, completely programmable, lasts 1-6 hours, has a replaceable battery, expandable, compatible with most arduino type microcontrollers and can be built in an afternoon. And you get to use a laser cutter...
Oh, and the princess gets to look stunning!
Did I mention lasers?
Shall we begin?
**Update*** After some new modifications, I've managed to fix the breakage problem, create the crown pattern on a single 11 X14" sheet of 3mm acrylic and make it a whole lot easier to create. I have heard comments that the vanes are too sharp but a finger nail clips or wire clippers would fix that if you were worried about pointy things. Flame polishing could help too.
