V1 case. 2aa batteries direct.

• 44x80x30mm (38 with sensors) 94grams...case has 4 loops 1.6mm walls.
• power use was about 40 idle and 80 peak on updates. so about 30 hours per pair...
• with about 10 ints per data point plus the date,  should be able to store about 1.5 minutes of data at 50hz.
• if i can use program space its more like 15minutes of data. but send out 2mB bursts might need a better connection.

tested this stl viewer demo app. will probably try to add this so I can create a Digital Board that mirrors the sensor data.

Then plotting some data might be useful once it has context.
