Here’s a cool DIY Arduino and Wiimote Controlled Boat all by flick of the wrist. Now, just don’t drop that Wiimote and you will have some serious trouble getting out of the water. (I am sure there’s a backup plan for that)
Last winter I decided version one was successful enough that I would dare to improve it. My design constraints were to extend the boats range to about 20 miles and add a second motor to balance the thrust and push the extra battery weight. In my nerdiness, I also figured it would be prudent to drive the boat with some sort of joystick, opening up the option for autopilot in the future. Lastly, I need to walk the boat to the water (0.3 miles) on a portage cart and launch and retrieve it by hand.
