Sunset Sailboards San Francisco

Time to plug Sergey from videojibe.com again!  This guy is one serious tinkerer whose many DIY projects have given us a cool POV for mast cams.  By using two mast cams, we can now see both sides of the sail, analyze hand and footwork during transitions, and get a more complete picture of what's going on.  Think of it as being hovered over by a helicopter... without the helicopter.

And now, we have these cams in HD.  I've posted some frame grabs to give you an idea of the quality... each cam records 1280 x 720, and the resulting full resolution video is these two video streams put together.  Of course, this video is too big to stream conveniently, so the video has been scaled.

For those of you who would like to make one of these setups yourself, here are some instructions:

These cams are not waterproof, so you'll have to encase them in some sort of waterproof bag.  Sergey fabricates his own "socks" from this material:  http://www.rei.com/product/752384

If you find smooth clear vinyl for less, let me know :) Socks are fastened with thin velcro ties ($5 for 50 at Home Depot, AFAIR)

I used a "1 inch PVC tee" and "3/4 to 1/2 PVC L joint" (3/4 end cap could be used instead), aluminium angle from Home depot, stainless bolt (2 inch or 1 3/4 - check in the store with 1 inch tee), wingnut and stainless washers.

This is remake of old kit http://videojibe.com/featured/mast-mount-for-gopro-digital-hero-video-camera/

Note that I cut off top and bottom collars from 1 inch tee clamp to save weight.
