Two revisions later we have something closer to "child tamper proof". Our prototypes are on their way out to many eager children! Hooray!
If you are interested in receiving them for your pilot please send me an email to: firstname.lastname@example.org. We will soon release a few prototypes for private purchase (under a G1G1 model to help finance further prototypes for the pilots). Stay tuned for more details.
Big thanks to Mike Koop and Dan Ehlers for their efforts on the latest PCB layout. Another big thanks to the guys at Liquidware/GL Interfaces for subsidizing the cost of a component.
