Blinking Iris Goggles with Battery Holder

thingiverse

In order to make some Blinking Iris Goggles with LED rings in the eyes, I'll need to supply it with power. Since there are already two strands of fishing line hanging from the goggles (to actuate the blinking), I decided to put a battery holder right on the goggles instead of having a wire going off into a pocket somewhere. I also wanted a way to detect actuation of the blink. I decided the best way to do this was have a small neodymium magnet glued to the rotating part of one of the eyes, and have it come near a reed switch which could be mounted to the battery box. I remixed the Right Eyeball file so it has a magnet holder that will accept a 5mm x 3mm magnet. The one in the video is a 4mm x 2mm. I made the reed switch holder separately to aid with assembly and to add the ability to print it in a different color. It can be glued on the battery box. I do not have a way to mount a 5v regulator and a digispark, but for now, the battery box and switch holder will be enough to make a prototype.
