Pushdown Button
The Pushdown Button is designed for people with issues using smaller button features. This device gives basic controls over a computer, while maintaining accessibility for those without fine motor skills. There are two large slots, with two bars connected to rubber bands. These bars push down and activate an action programable to a computer. This is a cost-effective alternative to other assistive technology devices.
This project took a lot of time and thought. I began without a method to connect the Earth, to the controller, I eventually decided on using legos to make a kind of ledge for it to connect because of how simple and easy they are to use and access.
Using larger more supportive buttons, people without fine motor skills can use this with device ease. It allows for any level of hand / arm mobility. Pictured at the bottom I use this device on a tabletop with my hands fully on top of the bars. This of course doesn't work for everyone. This design was intentionally made to be versatile, so whatever setup works for you is best. These instructions are simple guidelines so feel free to change anything that doesn't work right with you!

Glue/Solder the Two Frames Together
Use hot glue or any other adhesive to connect the two frames. I used a soldering iron, but of course if that is unavailable you should use whatever is easiest.
Create Ledge for Earth Clip
Create a design similar to the one pictured above, the only crucial aspect of this step is that you have a ledge for the Alligator clip to grab onto. You can use Legos as I did, or any other method you desire. Tape and a popsicle stick works great as alternative! Then connect it to the frame in whatever way works.
Add Copper Tape
Add copper tape to the bottom of the bars and around the frames as pictured (make sure the contact point between the bars and the frame connects solidly to the edge where the earth with clip on to).
Connect Bars
Add rubber bands to connect the bars to the top of the frame.
Clip the Alligator Clips
This is crucial. Add one clip on each one of the bars (!make sure they solidly clip on the the copper tape!), and clip another one to the ledge we attached on top.
Clip the Alligator Clips Into the Makey Makey
Make sure the clips attached to the bars connect to the two corresponding buttons that you want access to (Pictured, they are connected to the up and down button on a computer). And attach the clip connected to your ledge to the Earth.
Connect to Computer and Use
Connect the Makey Makey to a computer and use however you intend. *You may need an adaptor to connect to certain computers.
