Hello! Welcome to another Othermill project tutorial! I'm Sam DeRose, an intern here at Other Machine Co.
This project is a spin-off from my PCB Hummingbird Necklace. This time, I made it with the battery and switch built in so the necklace could be used as a pin. Now you can show off your glowing designs in many more places!
These pins are made from double-sided FR-1 circuit board blanks. The front is etched with the design and the back is etched with the traces for the electronics. All of the versions have a switch except the dragonfly—there was no room! To turn it on and off, you have to remove the battery.
This project assumes you have solid working knowledge of soldering and reading circuit board files to place components correctly.
Choose at least one of the following, all of which are in the .zip file attached to this step.
