While waiting for the new boards we have also started working on the design of the casing for the new modules. Surprisingly number of details to think about! Currently we are considering a snap-fit solution. A couple of guys from myobjectify.com helped me with the cad and printing. The day before yesterday I got a first crude print in my hand. The photos above show the size of the casing in comparison with an older unit and the casing with a battery and a partially assembled board in it (used for testing the wireless links).
