With a lot of help from a very patient friend, I had my first foray into electronics this weekend! I decorated an unChristmassy jumper to make it festive, and adorned it with LEDs. I created a circuit with LEDs, resistors and a battery pack, and sewed and glued them in place on my jumper.
See a picture of it, and a step-by-step guide of what I did, here: http://canthack.sdfsdfs.com/2010/11/ugly-christmas-jumper
Next week, I am hoping to add even more LEDs and make a matching hairband! Let me know what you think.
