Blinking Iris Goggles with Battery Holder

thingiverse

To power my Blinking Iris Goggles with LED rings in the eyes, I need to supply it with energy. Since two strands of fishing line are already attached to the goggles to activate the blinking, I decided to mount a battery holder directly on the goggles instead of running a wire into a pocket somewhere. I also wanted a way to detect when the blink is activated. To do this, I opted for a small neodymium magnet glued to the rotating part of one eye and a reed switch mounted to the battery box. This setup allows me to monitor the activation of the blink. I remixed the Right Eyeball file so it now includes a magnet holder that accepts a 5mm x 3mm magnet, although the one in the video is a 4mm x 2mm. To aid with assembly and offer flexibility, I created the reed switch holder separately, allowing me to print it in a different color if needed. The battery box and switch holder can be glued together for added convenience. For now, this setup will suffice as a prototype, but I still need to figure out how to mount a 5v regulator and a digispark. Here is a demonstration of the reed switch with a 4mm x 2mm magnet hot-glued on.
