After my last Mini RC Car project I knew I wanted to make a smaller better one. Some months later and this is the result:
The reason why this one is in a LEGO body is because of this question on LEGO Stack Exchange where it was asked if it was possible to power the small LEGO City wheels. At that point I had already started playing with micro DC motors and I also started using the ATtiny chip. This was a perfect storm. I had to build a super small LEGO vehicle.
Here are all the parts needed to make this build:

Here are all the parts needed to make this build:
- Set of gears from a race track car
- LEGO wheels set
- LEGO brick 2x2
- Micro motor
- 0.1uf capacitor
- Transistor
- Diode
- ATtiny
- Socket
- Power adaptor
I'll go over the small details in an Instructables ASAP. For now here's shot from the inside:
Here's a video where I show the final result:
