Step 9: Other Uses - Foot Switch
First, we made a pad (as in the main instructable). Next, we covered one of her little shoes with hot glue and then covered it in foil. One clip goes to the pad, the other to the shoe. She could activate toys by kicking her foot against the plate.
We also took her soft socks / baby booties and sewed the loop side of a piece of velcro to the sock. We hot-glued the hook side of velcro to a strip of aluminum foil that had been folded over a couple of times. This made a wide variety of adjustments possible, and allowed us to experiment with a lot of different configurations.
