Making an e-Vest (electronic vest)
Added Jun 1, 2010
Next, let's look at the wiring diagram for the vest itself. I've shown the positive circuit in green and the negative in orange (as my colors red and black are already used and I don't want to confuse things). Note that I have shown where to sew in the battery holders - I found the most effective place was just behind the side seams along the bottom (hem) edge of the vest. I used conductive thread that I obtained from Aniogram, one of the companies that makes e-kits for clothing, but I could have used regular wiring as well as the circuits were hidden away between the lining and the outer fabric (for the second project, I used wiring). Note that it is important to keep the two conductive channels separate - one of the difficulties of working with conductive thread is that there is a danger that folds in the clothing bring the two electric channels (negative and positive) together when you don't want them too. Wiring is safer this way, as it is insulated. With regard to connecting the wiring and/or conductive thread to the snap fasteners, I found it was simpler to do this before the snap was installed within the fabric. The conductive thread is particularly easy to manipulate, since it may be connected to the snap ring simply by tying and knotting it to the loop.
