2015-10-10 (Sa) Wrist Mounted Chording Keyboard

The model for the emitter and receiver tubes was revised to have a smaller hole for the receiver since it would be glued in place. A second LED mounting location was added but there was no need for a tube since it would simply be an indicator LED. An RGB LED will likely be used since they are inexpensive and plenty of outputs are still available on the controller.

E6000 glue was used to hold the TSOP4856 receiver and LED holders held the emitter and an RGB LED. Black liquid tape was used to coat the back of the receiver. A divider was going to be added to the model which would help eliminate any light leakage on the backside of the unit but it was decided that a light-blocking layer on the back would be simpler.
