Automatic wakeboarding in a pond

[Rick] sent in an awesome project he and his uncle [Charlie] have been working on for this summer. It’s a completely automatic wakeboarding system¬†that tows [Charlie] and company from one end of his backyard pond and back again.

The entire system is supported by two towers at either end of the pond. Strung between these towers is a 420 foot cable that pulls the rider from one end to the other before stopping, and automatically continuing in the opposite direction. Apart from stopping and starting the motor attached to the cable, no user input is required. This means anyone lucky enough to make it to [Charlie]‘s farm can wakeboard all afternoon without a break.

[Rick] posted a few short videos covering the internals of the system. From what we can see, the guys are using a LabJack U3-LV data acquisition unit to grab the speed, direction, and position of the rider. This data is sent to a laptop that controls the motor suspended on one of the towers.

There are a few more videos of this incredibly fun toy available after the break.
