Just thinking about the watch again and realized I had wanted to add a vibration motor to buzz for notifications like email, texts, calls, and other info, but hadn't added it to the pcb. I found an open pin on the FemtoduinoBLE and added it in on the top left of the PCB, perfect. The wires will be soldered there, and wind to an open part of the sandwhich either in the middle above the pedometer or below the flick switch over the battery charger, we'll see. I can find and use the smallest one, there are different kinds out there.
