Great work! How about calling -this- Elphel Vision?

BTW: LiPo works perfectly with the camera. I don't know yet how long the battery will run the camera though.

Rods support dimensions??

What are the standard/common dimensions for 15mm rods supports? I thought 60mm from center to center. But I also heard of 85mm and 100mm.
