Berto Aussems of Maastricht, the Netherlands, built a trolling motor powered by a drill.
Anyone with a cordless drill can make this trolling motor, just from wood. This is a fun project; making it, in a couple of hours, and to navigate on still waters. OK, you have to buy a propellor, a square drillhead, a strip aluminium, a trottle handle, a threated rod, screws and a plank of impregnated wood. This video speaks for itself; all is visible. The project is Open-Source Hardware. Now, make one for yourself and one for your best friend. Enjoy!
