One of the ways I get my middle school students interested in technology is by showing them some of the ways that technology is used for fashion. Videos and pictures are nice and all, but I wanted to make something real that the students could see and touch. I've made several little soft circuit "wearables" to show my class, but I wanted something with a bit more... edge. Or at least some middle school edge.
One night I came up with this crazy idea to make some earrings. Why, I don't know. It's not like I wear them or anything. I was just looking at some little round perf boards when it occurred to me that they'd be awesome as earrings, and the larger ones as necklaces. Something a bit cyber punk in nature.
And in case you were wondering, that is how I (of all people) came up with this simple design for some LED Earrings.
(Also this is an entry for the instructables 2012 LED contest. You should totally vote for us so we can have a light switch rave in our basement.)
Step 1: What You'll Need
Small Circuit Board/ Perf Board (eBay, one inch across)
3mm Diffused LEDs
CR2032 Battery Holder (Surface mount with rounded sides works very well!)
Magnet Wire (Thin and small is good)
Earring Clasp of your choice
Needle Nose Pliers
Helping Hand (optional, but helpful)
Total Cost: > $10
For the most part you can find the electronics parts easily on eBay, or even salvage them from somewhere else. The earrings parts can be gotten from any craft store (Hobby Lobby, Michael's).
We have a bunch of parts left over from when we did this (many months ago). If anyone would like me to make a Kit with all the parts in it we can. (We run a little hobby website BrownDogGadgets.com, though we mostly deal with solar kits and projects. Educational and whatnot.)
