doing the dishes, etc.
Modifying Your NeoGeo Watch
The real fun part of the NeoGeo Watch is hacking it to make it do
something new. The NeoGeo Watch has a ton of features
packed into a small microcontroller. The downside to this is

you to add any new features.
Unfortunately, all three of its functions rely on each other to
work properly. For instance, the clock uses the GPS module to
automatically set the time. The GPS navigation function uses
