2020-05-16 (Sa) Touch Atari Punk Console APCTouch

My aluminum bar had some scuffs, and I noticed that my first prints snagged on the corners, so I took a few minutes and a metal rasp to deburr rough spots. I think this helped. Another place I noticed snagging, was between the prints and ribbon, so I sliced away any plastic that would catch.

Before I mounted everything, I connected the Velostat ribbons and aluminum bar electrodes with alligator clips to make sure it all worked. I wouldn't enjoy tearing it all apart to replace a burnt capacitor. I was pleased that it worked, and I could change sounds with the strips.

During testing, I found that both resistors had to be connected, or the system wouldn't generate any sound. Part of the appeal of the linear touch resistors was that they would break the connection when released, so the device wouldn't draw power unless someone was playing with it. On one of the resistors, I tucked the far end of the Velostat strip into the metal bar socket, maintaining constant continuity at the highest resistance. By doing this, I could enable the sound by touching anywhere on the other resistor. On the other side, I put tape over the ribbon before tucking it so that it wouldn't make contact.

To keep the conductive strips from drooping and touching the aluminum, I added a rubber band around the midway holders to keep tension on both sides. I left space between the parts so I could mount the console on the bar too. A bit of tape across the bottom layer of Velostat kept the tail from touching the bar, and the added thickness kept it from pulling back into the holder.
