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

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.

Hacking A Pint-Sized Mercedes

[Jonas] bought an electric Mercedes “ride on” toy for his one-year-old son. At least that’s his story. However, the vehicle has become a target for dad’s obsession with hacking and he’s already done quite a few upgrades. Even better, he did quite a bit of analysis on what’s already there. He isn’t done, but he’s promised quite a bit in the next installment which isn’t out yet.

The original car can take a driver or it can use remote control. [Jonas] has an ambitious list of ideas, some of which are still not complete:

  • Speed along with softer acceleration and braking
  • Improve the radio controller
  • Proper rubber tires
  • Proper stereo system
  • Individual brake disks on the front wheels
  • Improved horn
  • Proper seat belt or maybe even a new seat
