I'm taking an old cell phone, and turning it into a smart racer. But just for an added effect, I would like to be able to display stuff on the screen.
I'm using as much of the cell phone as I can. I'm using the battery, I will add in a charging circuit to use the phone's charger. I'm using the tiny vibration motors (from a couple phones) to drive it. I stuck a couple LED's under the keypad to light that up.
Once it's complete, I'll post all my notes.
