Bite & Button - Adaptive Controller

The Bite & Button is a system featuring 2 separate switches that can allow someone with limited control of their movements to control a device such as their computer. The switches work by biting and smacking down on 2 separate buttons, allowing for control of a computer by various means such as cycling through options. This project makes use of a MakeyMakey, which allows us to control things on a computer through simple circuits.

If any of these instructions are unclear, feel free to let me know! I'll do my best to help.

This project requires very few materials:

1. A 3D printer & approximately 93.5g of PLA filament. (Due to how this project relies on the plasticity of PLA, it might not work with other plastics.)
2. Copper tape. (about 7 inches minimum)
3. MakeyMakey and its included alligator clips and connector to a USB device.

Using a 3D printer, print the 2 files attached below. These are essential to the project, as they are the base of the switches.

Apply copper tape to both sides of both switches as shown in the photos. This is necessary for the switches' functioning, as without the copper tape, there would be no completed circuit that the MakeyMakey can recognize. Although this step can be somewhat annoying, sliding the tape in from the open sides can make applying the tape much easier!

[Note: When applying the tape, make sure to put it on both sides! Otherwise, the switch will not work.]

Both of these models have a spot that is designed for alligator clips to be attached. Attach the alligator clips to the spots as shown in the photos

While straightforward, this is a necessary step. Make sure you connect the wires to the inputs that best fit what you need!

Once you plug the device into your computer using the provided cable with the MakeyMakey, you're all done! The switches are now ready to be used with any software of your choice!
