Flaming Power Wheels Skeleton Wins Halloween

November 5, 2024 by Jenny List 48 Comments

When the project description starts with the sentence “I use an RC remote and receiver, an esp32, high-current motor drivers, servos, an FPV camera, and a little propane”, you know that this is one which deserves a second look. And so [gearscodeandfire]’s Halloween project caught our eye. It’s a pink Power Wheels jeep driven by a skeletal rider, and the best part is that the whole thing is remote controlled down to a pan-and-tilt skull, a first-person video feed, and even real flames.

At its heart is an ESP32 with a set of motor controllers and relays to do the heavy lifting. The controller is a standard radio remote controller, and the first-person view is an analogue feed as you’d find on a drone. The skeleton is given a child-like appearance by discarding the original adult-proportioned plastic skull and replacing it with a much larger item. The thought that plastic Halloween skulls are available in a range of standard sizes and can be considered as a part in their own right is something we find amusing. The propane burner is supplied from a small cylinder via a solenoid valve, and ignited with the spark from a high-voltage transformer.

The result, we think, wins Halloween hands down. Twelve-foot skeletons are SO 2023!

Converted Car Lets Toddlers Tool Around

February 10, 2020 by Kristina Panos 9 Comments

A few years ago, a professor at the University of Delaware started a project called Go Baby Go. It’s designed to bring fun and affordable mobility to small children with disabilities. The idea is to modify Power Wheels cars to make them easier for disabled kids to operate, and to teach as many people as possible how to do it in the process. The [South Eugene Robotics Team] is taking this a step further by replacing the steering wheel with a joystick that controls two motors with an Arduino Nano.

In the first instance you replace the foot pedal with a push button. The plans also call for a PVC frame, a high-backed seat, and a seat belt to make it safer. The end result is a fun ride the kid can control themselves that functions a lot like a power wheelchair, but is much more affordable. It has the added bonus of being a fun conversation piece for the other kids instead of a weird scary thing.

They also replace the front wheels with 5″ casters, because being able to spin around in circles is awesome. Their project shows how to do the entire conversion in great detail, starting with a standard ride-on car that comes with some assembly required. Motor past the break to check out a short demo with an extremely happy child tooling around in a fire truck.

If these kids get too wild, they’re gonna need traction control for these things.

This Upgraded Power Wheels Toy Is Powerful Enough To Need Traction Control

June 23, 2019 by Jenny List 17 Comments

A Lamborghini Aventador Is beyond the budget of all but the most well-heeled fathers, but [CodeMakesItGo] came pretty close with a gift for his young son. It was a Lamborghini Aventador all right, but only the 6V Power Wheels ride-on version. As such it was laclustre even for a youngster in its performance, so he decided to give it a 12V upgrade. This proved to have enough grunt to cause wheelspin on those hard plastic wheels, so a further upgrade was a traction control system featuring a NodeMCU. No other child has such a conveyance!

Veterans of the Power Racing Series or Hacky Racers might have expected to see a Chinese motor controller in the mix, but instead he’s used a set of relays for simple on-off control. The traction control has a pair of 3D-printed sensor wheels that operate upon a corresponding pair of optocouplers to provide feedback to the NodeMCU. A set of different drive options were tried, with finally an H-bridge board being found to be most reliable.

The video below the break shows the hardware, and goes into some detail on the software. The NodeMCU’s WiFi is used to provide some tweakability to the system on the go. The traction control turns out to lower the standing start speed a little, but makes the machine more controllable by its driver. he certainly seems happy with his toy!

Long-time readers will know this isn’t the first Power Wheels upgrade we’ve shown you.

Hackaday Links: March 17, 2019

There’s now an official Raspberry Pi keyboard and mouse. The mouse is a mouse clad in pink and white plastic, but the Pi keyboard has some stuff going for it. It’s small, which is what you want for a Pi keyboard, and it has a built-in USB hub. Even Apple got that idea right with the first iMac keyboard. The keyboard and mouse combo are available for £22.00

A new Raspberry Pi keyboard and a commemorative 50p coin from the Royal Mint featuring the works of Stephen Hawking? Wow, Britain is tearing up the headlines recently.

Just because, here’s a Power Wheels Barbie Jeep with a 55 HP motor. Interesting things to note here is how simple this build actually is. If you look at some of the Power Wheels Racing cars, they have actual diffs on the rear axle. This build gets a ton of points for the suspension, though. Somewhere out there on the Internet, there is the concept of the perfect Power Wheels conversion. There might be a drive shaft instead of a drive chain, there might be an electrical system, and someone might have figured out how someone over the age of 12 can fit comfortably in a Power Wheels Jeep. No one has done it yet.

AI is taking away our free speech! Free speech, as you’re all aware, applies to all speech in all forms, in all venues. Except you specifically can’t yell fire in a movie theater, that’s the one exception. Now AI researchers are treading on your right to free speech, an affront to the Gadsden flag flying over our compound and the ‘no step on snek’ patch on our tactical balaclava, with a Chrome plugin. This plugin filter’s ‘toxic’ comments with AI, but there’s an unintended consequence: people ~~want~~ need to read what I have to say, and this will filter it out! The good news is that it doesn’t work on Hackaday because our commenting system is terrible.

This week was the 30th anniversary of the World Wide Web, first proposed on March 11, 1989 by Tim Berners-Lee. The web, and to a greater extent, the Internet, is the single most impactful invention of the last five hundred years; your overly simplistic view of world history can trace modern western hegemony and the reconnaissance to Gutenberg’s invention of the printing press, and so it will be true with the Internet. Tim’s NeXT cube, in a case behind glass at CERN, will be viewed with the same reverence as Gutenberg’s first printing press (if it had survived, but you get where I’m going with this). Five hundred years from now, the major historical artifact from the 20th century will be a NeXT cube, that was, coincidentally, made by Steve Jobs. If you want to get your hands on a NEXT cube, be prepared to pony up, but Adafruit has a great authorial for running Openstep on a virtual machine. If you want the real experience, you can pick up a NeXT keyboard and mouse relatively cheaply.

Sometimes you need an RCL box, so here’s one on Kickstarter. Yeah, it’s kind of expensive. Have you ever bought every value of inductor?

Power Wheels Gets Real With Real Wheels

December 19, 2018 by Tom Nardi 10 Comments

We’re no stranger to Power Wheels modifications, from relatively simple restorations to complete rebuilds which retain little more than the original plastic body. These plastic vehicles have the benefit of nostalgia to keep the adults interested, and naturally kids will never get tired of their own little car or truck to tear around the neighborhood in. Many toys come and go, but we don’t expect Power Wheel projects to disappear from our tip line anytime soon.

Today’s project starts with a straightforward Power Wheels restoration story: [myromes] picked up a well-worn Jeep and decided that it needed a fresh coat of paint and some tweaks before handing the keys over to the next generation. But in an interesting spin, he decided to try mounting proper pneumatic tires on it in hopes they might imbue the pint-sized Jeep with some of the abilities of its full scale inspiration. But as it turned out, the project wasn’t quite the Sunday drive he was hoping for.

For one thing, the new wheels were much thicker than the old ones. This meant cutting away some of the plastic where they mounted so he could get the shafts to slide all the way through. At 5/16″, the original Power Wheels shafts were also thinner than what the axle the wheels were designed for. Luckily, [myromes] found that a small piece of 1/2″ PEX water pipe made a perfect bushing. Then it was just a matter of buying new push nuts to lock them in place.

That got the front wheels on, but that was the easy part. The rears had to interface with the Jeep’s motors somehow. To that end, he cut out circles of plywood and used an equal amount of Gorilla Glue and intense pressure to bond them to the new wheels. He then drilled four holes in them which lined up with the original motor mounts so he could bolt them on.

Things were going pretty well until he tried to replace the Jeep’s rear axle with a length of threaded rod from the hardware store. It wasn’t nearly strong enough, and sagged considerably after just a few test rides. He eventually had to place it with a correctly sized piece of cold rolled steel rod to keep the car from bottoming out.

While the new wheels certainly perform better than the original hard-plastic ones, there’s a bit of a downside to this particular modification. The slippy plastic wheels were something of a physical safety to keep the motors and gearboxes from getting beat up to bad; with wheels that have actual grip, the Jeep’s stock gears are probably not long for this world. But [myromes] says he’s got plans for future upgrades to the powertrain, so hopefully the issue will be resolved before the little ones need a tow back home.

For more tales from the Power Wheels garage, you might want to take a look at this fantastic rebuild complete with digital speedometer or just head straight to the big leagues with some seriously upgraded rides.

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.

Power Wheels Rescued, Restored And Enhanced

November 14, 2016 by Steven Dufresne 14 Comments

It seems power wheels are like LEGO — they’re handed down from generation to generation. [Nicolas] received his brand-new Peg-Perego Montana power wheels in 1997 as a Christmas present. After sitting in a barn for a decade, and even being involved in a flood, it was time to give it to his godchildren, though not without some restoration and added features. His webpages have a very good write-up, just shy of including schematics, but you’ll find an abbreviated version below.
