Fresh hacks every day
We've heard quite a number of radio ads lately trying to sell an automatic lawn mowing robot (like a Roomba for your grass). But wouldn't it be a lot more fun to hack your own from an existing lawnmower? That's what [Daniel Epperson] did. In fact, the project has been ongoing for years.

Backyard parties are going to rock over at [Effin_dead_again's] house. That's because he just finished building this outdoor stereo. It carries its own power supply so you can take it on the road with you, and we don't think you'll have trouble hearing it with the 240 Watt amplifier hidden inside. He shared the equipment details in his Reddit conversation. A 12V lawn mower battery sits in the … [Read more...]

In his Instructable writeup, he details each misstep he made, explaining why his choices were bad as well as how much each mistake cost him. It … [Read more...]

Since the battery was brand new (and probably costly too) there must be something else. Checking the brushes, which were fine, the next logical place was the switch.These mowers are just a battery, … [Read more...]
There's the quiet serenity of paddling through the backwoods in a canoe, and then there's this. It's a lawnmower motor powered canoe that comes complete with steering wheel, throttle, and a stereo system. To keep the craft balanced the driver rides in the front seat while the motor is hanging off the stern of the boat. The biggest trick is not swamping the thing while getting the motor running, … [Read more...]
