Mechanical Dry Erase Board

Step 10 Gear shafts and controller board setup.

I did not mention this before, but I made my gear shafts by using a nail shaft that was slightly smaller than the bore of the gear. I slipped the gear onto the nail, tapped the end of the nail and then nailed it into either the wood, or the pvc pipe. I drilled into the pvc pipe before nailing. The tape was used to add grip.

To hook up your phidgets controllers, use the product manuals. The program I wrote is a console based app, and is designed to work with the phidgets controllers. In order for this to work properly, the motor from the Y component must be screwed into the motor 0 slot. Hook the battery up by connecting speaker wires from the positive of the battery to the positive in the HC motor controller. Do the same with the negative.
