RF Handpad

The new RF handpad. It communicates with the GOTO computer at 28800 baud on the 900MHz frequency band. Keyboard backlight, display contrast and display backlight are individually configurable.
Case opened, with the daytime display installed.
Case opened, with the nighttime display installed (red characters).
Display removed. RF module visible.
Keyboard PCB. The system uses five AA batteries and it can display the batteries level.
Keyboard close-up. The leds are used to illuminate the keyboard (in red).
Holes are made where the keyboard micro switches are positioned.
The 2nd handpad that I will build will use this black case.
