Modified the original design a bit, moving up to 2″ aluminum bar stock for the cross, to allow for the camera to hang on the same plane as the balloon string.
I also added a bucket, which I’ll foam up in an attempt to protect the camera in a bombs away scenario. 2 and a half quarts of security theater!
Update: I walked over to Printing Services and weighed the picavet rig with camera in place. 1 lb, 3.2 ounces. Given the helium shortage, we’re looking into kites as an alternative, and the rig weight will inform the kite selection process.
