There were only 4 days between the announcement of the Wildcard winners (Oct. 19) and the deadline for the grand prize (Oct. 23). It simply is not enough time to complete both the prototype and all the requirements by that deadline (especially compared to other categories that had months).

Sorry everyone about the missed opportunity. Hope everyone following the project will keep on, as there will be more updates posted.

Please enjoy this video of the functional electronics prototype being tested — outdoors, in frigid waters:
