Here are some images of some material and process tests Kurt has been doing on the case and key caps, as well as some shots of the first prototype of the internals.
Test from a seven-ply bamboo sheet. This is a candidate for the final material.
Test made of MDF, which is not a candidate for the final material.
A fully populated prototype of the printed circuit board, along with some test key caps.
A midway point in one of the processes Kurt tested for milling the key caps out of a block of aluminum.
