Kids Electric Mini Goes Brushless, pops wheelies

[ThatHpiGuy] had a problem. He wasn’t impressed with the performance from his kids’ electric-powered Mini. The 6 volt system was anemic at best, and was just begging for an upgrade. Pulling off the seat and checking the undercarriage, [ThatHpiGuy] realized the motor and gearbox were a perfect fit for the Turnigy 2300 Kv motor from his R/C short course truck. A couple of screws later, car-docuand he had the fastest ride-on toy on the block. Since this was a quick hack, [ThatHpiGuy] kept the truck’s R/C receiver, electronic speed control, and 2 cell LiPo power setup intact. The result is a cooperative system where he controls the throttle via R/C, and his kids control the steering.

That steering is still a bit of an issue though. Like many kid toys, the Mini only has one drive wheel, in this case the right rear. If [ThatHpiGuy] pours on the power a bit too quickly, the single wheel either spins or forces the car into a hard left turn. Aside from that, it looks like both [ThatHpiGuy] and his children are having a ball with this hack. The car will even pop a wheelie from a standing start! You’ve got to see it after the break.

Hacking the MINI Cooper


[war6763] sent us this hack to power an amplifier in a MINI Cooper. Apparently, aside from being unconventionally handsome, they’re also unconventionally wired. Amplifiers are generally wired to the ignition or stereo and turned on when the car is turned on. Due to some strange wiring, this just isn’t possible in the MINI Cooper. Some people use the cigarette lighter to power on their amplifier, but [war6763] wanted something that left his cigarette lighter free for other things. He built a circuit that monitors the cars built in USB input line and turns his amp on and off accordingly. The entire unit cost around $10.00. You can see the video demonstration after the break.
