You might not look at an ESP8266 programmer and think wearable Ouija board planchette earring, but Alex Glow did. And given all of the arty boards that you can have fabbed these days, that’s exactly what she did.
The circuit design is an update of one by Alasdair Allan in Make:. Alex designed her board in KiCAD and had them fabbed at Oshpark.
You can see the whole project at Hackster.io here.
