Ermehgerd. I joined the Adafruit Show and Tell Google Hangout last night, and got to show off the prototype of the hoodie sleeve! My audio didn't work, so I had to play Maker Charades, but the demo was still successful! Here's the link, I'm at 17:36

Excuse me while I squeal like a fangirl.

Anyways, we have updated construction! I realized I was going about this in totally the wrong fashion, what with the snaps and the soldering. So here's a couple of lessons learned:

1. Soldering to snaps that are already sewn onto fabric is a Bad Idea. Now my sleeve has holes in it.

2. Practice what you teach. I already knew how to make wire leads into sewable components. I was just being stubborn.

So here's the new construction, which is probably also the final construction, because it doesn't short out and seems to take care of any responsiveness issues:

So as you can see, I've nixed the ribbon cable in favor of a set of silicon-coated stranded wire jumpers between the accelerometer and the Flora. The ends of the wires are stripped down about an inch, then coiled into small rings and stitched down with conductive thread, connecting them to the components. There's enough slack in the wires that they shouldn't pull loose while being worn, but not so much slack that they take up much extra space.

So that's Version 0.2 of the tech wizard hoodie sleeve. I still need to sew down a pocket for the battery, but otherwise I think it's pretty much ready to become part of an actual Hoodie!
