As an electronics engineer and maker, I found myself using my digikey ruler all the time to check the gauge of unmarked wires. And also to quickly figure out the soldering holes to add to my PCB designs. However the ruler is hard to carry around everywhere and I found myself forgetting it when I was on the field, elbow deep in tinkering or debugging.

So I designed these pretty wire gauge PCB earrings that are easy to wear and carry around and are not only pretty but also super handy to get my job done.

And they make me feel like Nancy Drew, if she was an engineer :D
