Have been too busy to program the past couple days, but I did cut the buttons shorter and add some white rubber caps that fit nicely over the buttons. The buttons I used on this prototype had 12mm actuators that stuck out way too far. Now they are a good height and the rubber caps feel nice to push.

I also put some velcro on the side so i can stick it on the side of my window frame to charge

I am hoping to finish the interpreter code this weekend and then move onto component list, build instructions, and user guide for programming device with TGRK interpreter.
