Use every RC Toy Transmitter as a game controller

To play a race game on a PC you use either a steering wheel or the keyboard. In my case, I rarely play games so I don’t own a steering wheel. My brother use a rc wheel controller to control his rc car.

My idea was to connect this transmitter to my pc as a game controller. Here’s the result:

Components:

• RC USB Interface
• 2.5mm 3.5mm audio jack (depends on the RC USB Interface)

Tools:

• soldering iron
• screwdrivers to open the case of the transmitter

How-to:

1. First you have to open the transmitter case
2. Now you have to search for the ppm signal
   I used a soundcard oscilloscope for this job
3. Connect the audio jack to the ppm signal using the soldering iron

Important: You have two lines on the oscilloscope. Put one line to the ground and with the other line go throught the pins of the microcontroller.

Now you can plug in the RC USB Interface to the transmitter and to the PC.

In Windows XP, the interface should be recognized as a game controller.

Have Fun.
