Step 4Glue the rod in
Now you'll need to find a metal rod that will fit through the middle of your encoder (I used a piece that I had lying around, you could maybe use a thin nail or some thick and quite stiff wire, maybe from one of those massove paperclips).
Once you have your rod, cut it to about 3 inches long or shorter. It needs to be long enough to fit through the encoder, one side of the project box and a good way into the wheel of your R/C car.
Glue it in to the rotary encoder by putting a small dab of superglue onto the rod and sliding it in to the hole in the encoder's centre. Let it dry, and if the metal rod can turn the encoder, you're in business. Otherwise, use a knife to scrape away where you've stuck the rod to the edge of the component and try again. You'll find it turns very easily with the rod stuck in it.

hahha thats great. You said there is a commercial product for this purpose? I have a mouse with a infrared laser instead of the rubber ball, and a little wheel between the "click ' buttons.
