Micro Racer is a build-it-yourself racing kit that teaches embedded systems through play. You assemble it, drive it, and trigger real power-ups on the track. It ships pre-programmed so you can race first, then hack the code when you are ready.

Assembly and simple soldering are required.

Lite is the racer kit. Pro adds the physical controller and community access.

How It Works

You’ll assemble it, learn the tech behind it, and race a fully functional smart car powered by an ESP32H2 microcontroller.

  1. Assemble the kit
  2. Race and Have fun
  3. Hack and customize
  4. Expand and learn with a community of likeminded engineers

This Little Car Has Superpowers

This tiny car can see colors and sense magnetic tracks, transforming every race into an interactive game. Grab the red mushroom for a burst of speed, but avoid the yellow banana waiting to spin you out.

There are 3 power-ups:
Yellow Banana – spins your car out of control
Red Mushroom – gives you a burst of speed
Blue Splash – slows your car down

Learn and Hack

As a bonus with your Micro Racer Build Kit, you’ll gain exclusive access to a private community where you can:

  • Learn through hands-on engineering walkthroughs
  • Join live Q&A sessions
  • Master embedded systems, firmware, and hardware design

Whether you’re a beginner or a pro, this is the perfect place to level up your skills while having fun!

Really, a big thank you to all of you who have followed, commented and encouraged me to do this on my YouTube channel. This journey has been incredible and I cannot wait to finally get these into your hands. So many of you have asked and I am finally taking the leap. I really hope to make it worth it for every one of you out there. Thanks again :)

As Seen In

We Didn't Say This...

I recently finished making one from scratch, the car is an absolute blast to play with. If you enjoy playing Mario Karts then you will love playing with this car. I enjoyed the building process just as much as playing with it. That being said, if soldering tiny components isn't your thing then definitely give the prebuilt KIT a try, you will absolutely love it.

From My Lab to Your Workbench

Every Micro Racer is built in small runs in my lab and packed by hand before it ships.

This is not a mass-produced gadget. It is a project I designed, tested, and refined myself.

When you order a Micro Racer, it comes directly from my workbench to yours.

I care deeply about the experience, the quality, and making sure it is something you are proud to build.

I am proud to make these kits in the USA and stand behind every one that leaves my shop.
