Testing out my version of the Granthony cam. Difficult to stabilize and align by oneself. I fashioned it in a similar way to the Granthony... a skateboard wheel bolted through the helmet, a PVC adaptor, a fiberglass driveway marker stem, and Gorilla tape. Getting camera aimed and leveled is the challenge, and the weight of it at arm's extension makes the helmet shift. A counterweight, perhaps?
