Here we have a toy car modified to use a drill as the powertrain. [Hans] has thrown a 12v 4.5 amp battery in to power the motor and it tops out around 9 miles per hour. This is similar in concept to the trash-based go cart from last week but this time there’s video. He’s built a couple of these and there’s footage of both after the break. Our favorite part is from the first video when dad chuckles with glee from behind the camera as son whips around the neighborhood on the mean-sounding machine.
A quick lesson on being a good parent. If you make an awesome electronic cart out of trash that may not necessarily be stable, or even fully capable of stopping once it gets going, you MUST put your children on it and insist that they drive. Did we mention that the system is full acceleration or no acceleration? Indeed, it is. There isn’t a writeup, and one really isn’t needed. This is dead simple. The parts list will explain most of what is going on, but the look of doubt and fear on the kids face is what really makes this hack worth it. Or is that possibly a look that says “what are you looking at?”
