Larson scanners were traditionally red (or yellow in KARR's case), but thanks to the magic of NeoPixels you can change the software to use any colors you like.
This is a soldering project, albeit a small one. You will need the common soldering paraphernalia of a soldering iron, solder, wire (20 to 26 gauge, either stranded or solid) and tools for cutting and stripping wire.
You’ll need some method of securing the electronics inside the glasses. Hot-melt glue (with a glue gun) works well for this. Watch your fingers! Packing tape could also be used.
- Visor-style sunglasses — the 1980’s style with a single “unibrow” rather than separate lenses. A well-stocked costume store may have something suitable, or you can search eBay for “robot sunglasses,” “Devo sunglasses” or “alien sunglasses.”
- NeoPixel RGB LED flex strip: 144, 60 or 30 LEDs/meter depending on your budget and desired look. This project only requires a short section — you can either make several pairs of glasses from the strip, or use the leftovers for other projects (it’s fun stuff to play with!). The photo above is using 144 LEDs/meter NeoPixel strip.
- Adafruit's Trinket M0 or Gemma M0 are recommended. The legacy versions Trinket 3.3v, Trinket 5v and Gemma v2 will also work.
- 3.7V 150mAh Lithium-Ion Polymer Battery
- LiPo battery charger
- JST Battery Extension Cable (not required if using Gemma)
