Below are some frame grabs of video recorded using the ATC2K.
Kurt Raihn's ATC2K site
This site was created to let others see the modifications I have done to my Oregon Scientific ATC2K waterproof action cam.
I use the ATC2K in two different modes.
1. Mounted on my wrist using the factory lens.
2. Mounted on my surfboard with a wide angle lens attached in front of the factory lens.
For wrist mounting I created a strap using the supplied velcro and attached it to an old shoulder support strap from a laptop carrying case. This gave the wrist mount more stability than just using the velcro. I also use an elastic elbow support between my wrist and the strap to prevent the strap from rubbing my wrist raw. See Picture 1 below.
Next, I attached a small piece of PVC to the side of the ATC2K using velcro and a zip-tie. Because the ATC2K does not have an LCD display, I needed to create some sort of sighting device to allow me to know if I was framing my subject. The tube works great. I just look through the tube and spot my subject and the subject is in frame. I also glued a small level to the back cover to ensure that the ATC2K is level during recording. See Picture 2 below.
When using the wrist mount I can easily duck-dive waves and take off without any interference from the camcorder. When recording, I just sit on my board, point and shoot.

Next I outfitted my ATC2K with a wide angle lens (0.42) and attached it to my surfboard. In order to maintain the original waterproof nature of the ATC2K I chose to simply attach an external lens to the unit. I first cut a PVC adapter that had external threads and an inside diameter equal to the ATC2K near the lens (I think it was a 1 inch PVC adapter). I the epoxied (using a 2 part epoxy) the PVC piece to the front of the ATC2K. I did have to increase the inner diameter of the PVC to allow it to fit snugly over the ATC2K. I just used a knife to shave back the inside until it fit.
Next I took a threaded PVC adapter that mates to the piece I just epoxied to the camcorder and epoxied my wide angle lens to it. I am still able to disassemble the lens so I can clean all the optics. Once the epoxied parts were cured the camcorder was ready. See Picture 3 below.
My criteria for mounting the ATC2K to my surfboard included the ability to change the camera position easily and provide a stable and strong support so the camcorder wouldn't shake or wobble during recording or fall off if I got worked by a wave. I decided to drill a hole in the deck of the board and epoxy a threaded plug into the hole. This would allow me to screw a piece of PVC into the plug and attach the ATC2K to the PVC using the supplied handlebar piece. See Picture 4 of plug in surfboard and Picture 5 of PVC post screwed into plug.
I then screwed the lens onto the ATC2K and attached the complete unit to the PVC post using the handlebar attachment. See Picture 6 below.
I then made some tests to determine the best elevation of the camcorder. I found with the lens I had and the distance to me while riding that an elevation of about 30 degrees worked best.
