A Faster Grave Digger For Your Child

March 10, 2018 by Lewin Day 12 Comments

Children love speed, but so few of those electric ride on toys deliver it. What’s a kid to do? Well, if [PoppaFixit]’s your dad, you’re in luck.

This project starts with an unusually cool Power Wheels toy, based on the famous Grave Digger monster truck. During the modification process, it was quickly realised that the original motor controller wasn’t going to cut the mustard. With only basic on/off control, it gave a very jerky ride and was harsh on the transmission components, too. [PoppaFixit] decided to upgrade to an off-the-shelf 24 V motor controller to give the car more finesse as well as speed. The controller came with a replacement set of pedals, both accelerator and brake, to replace the stock units. On the motor side, a couple of beefier Traxxas units were substituted for the weedy originals.

Acceleration is now much improved, not just due to the added power, but because the variable throttle allows the driver to avoid wheelspin on hard launches. It also makes the car much more comfortable and safe to drive, thanks to the added controllability. Another way to tell the project was a success is the look of pure joy on the new owner’s face!

This was a fairly basic install, very accessible to the novice. These sort of electric vehicle hop-ups are commonplace enough that there are a wide variety of suppliers who sell easy-to-use kits for this sort of work. For that reason, we’ve seen plenty of hacks of this sort – like this modified scooter, or these Power Wheels set up for racing.

Kids Electric Mini Goes Brushless, Pops Wheelies

June 10, 2015 by Adam Fabio 40 Comments

[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, and 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.

Powerwheels Racing Series In Detroit

April 20, 2015 by James Hobson 13 Comments

[Transistor-Man] and the gang finally got around to documenting their experience at the Detroit Makerfaire 2014 and the Powerwheels racing series. They weren’t planning on entering, but in a last-minute decision they decided to see if they could whip up an entry just over one week before the competition! They did — and it’s awesome. They call it the Chibi-Atomic-Jeep.

As the competition name implies, they had to base the vehicle off of a Powerwheels frame. Bunch of steel tubing, some TIG welding and a nice paint job, and they had the base frame of their vehicle. At the heart of it? An alternator from a van — surprisingly powerful and easy to control. They used cheap 8″ wheels from Harbor Freight Tools — they worked great, just didn’t last very long… By the time the races were over, they went through NINE of these tires. Good thing they’re cheap!

The most impressive part of the build is the gears. They made them using a water-jet cutter at the local hobby shop and a Bridgeport mill with an indexing head — not an easy task to complete!

Jeep Power Wheels Upgrade Only Reuses Body

Power Wheels Racing Jeep

It is debatable whether [Jamie] upgraded his Power Wheels Jeep or built a beast of a mini vehicle and only added a Power Wheels Jeep body. Either way, this Racing Power Wheels Jeep is awesome. The goal of the project is to race in the Power Racing Series races held at Maker Faires.

This vehicle is no joke. It is still electric but runs on 24volts DC. It has pneumatic rubber tires for traction and disk brakes for stopping. The ‘gas’ gauge is a volt meter mounted into the dash next to the motor temperature gauge. As if that was not enough, the headlights and tail lights work. Take note of that sweet custom frame, it was mostly made from an old bed frame.

This Is Not Your Father’s Power Wheel

April 12, 2014 by Rich Bremer 36 Comments

If you had a Power Wheel vehicle as a kid you may have been the envy of the neighborhood. Even as fun as they were you probably out grew them. Lucky for a few youngsters, [Bob] hasn’t. Not only does he have several Power Wheels for his children to use, he does some pretty cool mods to make them even more fun.

Changing the stock motor out for a cordless drill is one of the first things that gets done. A few brands have been used but the Ryobi 18v Cordless Drill is the favorite. The entire drill is used, including the reduction gearbox. The gearbox is switched to LOW gearing so that the drill has enough torque to move the combined weight of the vehicle and child. As much as it may sound odd to use a drill in this manner, the Power Wheel can get up to about 15 mph. A stock Power Wheels maxes out at 5 mph

Halloween Hacks: An Evil R/C Clown Car For Terrorizing The Neighborhood

If you had a few too many trick or treaters hitting up your house this year, [phwillys] has a solution guaranteed to keep them from coming back. He was looking for a way to scare the crap out of the trick or treaters this past Halloween, so he constructed a remote-controlled evil jeep to terrorize the neighborhood.

The jeep was built from an old PowerWheels car, and uses a bunch of different motors to get the effect [phwillys] was looking for. He bought a linear actuator on eBay to let him steer the jeep, which is controlled using some motor controllers he had left over from another project. A salvaged car window motor was used to allow evil clown driver to turn from side to side in his seat, while a pair of car seat motors activate the giant claws built into the sides of the vehicle. The jeep’s hood was even turned into a chomping mouth with large teeth using yet another small motor.
[phwillys] also added a water sprayer to the clown’s mouth, soaking any kids in the immediate vicinity, though he was nice enough to mount a leaf blower on the opposite side of the vehicle to help blow them dry.

It really is an awesome creation, we’re sure the neighborhood kids (and parents) got a big kick out of it. Continue reading to see a short video of his scary clown car in action.

Warthog Laser Tag

April 12, 2010 by Mike Szczys 11 Comments

The Warthog from Halo is one of the most beloved video game vehicles. [Tim Higgins] brings the fun to life with his laser tag Warthog game. It uses Barbie Power Wheels toys as a base and adds laser tag weaponry. Xbox 360 controllers are used but just like in Halo, you can’t control the gun and the vehicle at the same time. We’ve encountered [Tim’s] love for water-based amusement before and this did originally start out with a water cannon powered by a wind-shield washer reservoir.

Take a look at the videos after the break as well as his recent post for information about the hardware. His choices for controller circuitry are way overpowered, sourcing an Eee PC to do the heavy lifting. This is because the choices he made were for easy development and not economy of components. A PC has no problem connecting to Xbox 360 controllers, and the modular control boards mean no complicated circuit design or arduous soldering were necessary. In the end, this looks like a ton of fun and we give him bonus points for repainting the pretty pink plastic that comes standard with these models of children’s toys.
