I wrote up a big thing about it, but it got deleted, so the short version
I've been playing around with the idea of a cable cam for my go pro
i had my friend weld up a frame, and strung up some cable
I didn't think i needed a tensioning system, but i think that might have led to some of the bouncyness seen in the video.
I think in the future i will try and use my slackline to tighten the cable
I am going on a big weeklong kayak trip tomorrow where i will get this setup dialed in i hope, but i'm pretty happy with this, being my very first test
I'll post up more when i get home
I'll put the test video up when vimeo finishes converting it
