One more version of the pendant, this time with the mechanical power switch replaced with an AT42QT1012 chip. This thing is tiny — about 2mm on a side — and I had to make a custom footprint for it. Of course Fritzing decided to not cooperate and rolled out all of its SVG parsing bugs. I got it to a state where it should probably work, but it's not pretty.
I actually ordered this version, we will see in a few weeks how it works.
