The RF glow stick handle and pcb have been updated to allow access to the power switch and a control button without having to open the case. The biggest update is in a BLE master controller which can relay commands from BLE (using an Adafruit nRF8001 breakout) over RF, enabling app-based control of the glow sticks. TechBasic on an iPad are shown as a proof-of-concept demonstration.
All design components are available on Github: https://github.com/jmkao/rfglow
