## Design and Fabrication
First, we decided to start off with making a rectangular frame for clamping firmly the membrane (wire plotting on 25 micron kapton tape) that Sam initially designed for another project of his. The frame contained pockets on each side for placing the "rubber" that will create friction between the frame plates. We used the Epilog Lasercutter to lasercut the frames on 1/8" acrylic sheet. For the pocket, we used 60% speed, 100% power, and 200ppi, for the outline of the frame we used 3% speed, 100% power, and 200ppi.
