## The Idea ## The Idea
When I was a child, I used to play a lot with my slot car racing track. When I was a child, I used to play a lot with my slot car racing track.
After stubling upon it again recently, I started wondering if I could build something to control it over the network. After stumbling upon it again recently, I started wondering if I could build something to control it over the network.
Not that I needed a remote control for it, but it seemed like a fun project. Not that I needed a remote control for it, but it seemed like a fun project.
However, simply creating an API that offers precise control over the device seemed way to sriaght forward - the controling mechanism itself should add its challenges.

The more traffic is sent to the remote control, the faster the car is supposed to go.[°Use more bandwidth!!!] The more traffic is sent to the remote control, the faster the car is supposed to go.[°Use more bandwidth!!!]

The underlying mechanism is fairly simple. The power supply provides about 14.8 V DC voltage, which a used to power the car's motor. The underlying mechanism is fairly simple. The power supply provides about 14.8 V DC voltage, which is used to power the car's motor.
The speed of the car is controlled by a variable resistor within the controller, which allows to control the voltage the car receives. The speed of the car is controlled by a variable resistor within the controller, which allows to control the voltage the car receives.
Pushing the controller further down lowers the resistance, which raises the voltage available to the car and makes is go faster. Pushing the controller further down lowers the resistance, which raises the voltage available to the car and makes is go faster.
A third wire is used to brake the car when the controller is in its neutral position by utilizing the current generated by the motor when the car is rolling out.
