My sibling just sparked my brain and lit up my proverbial light bulb giving me an idea for volume control that's kind of neat because it could potentially work with my Force-Sensing Linear Potentiometer (FSLP) button idea. The original concept is still that when you press down on the FSLP it acts like a button, and I'm still considering on having it increase the frequency of the Sonic Screwdriver sounds the harder you press down. The volume control idea builds on that by letting you drag your thumb towards the left or right to decrease or increase the volume of the sounds, respectively.

I think it would be fantastic if I could get this to work! It's kinda funny that this didn't dawn on to me a lot earlier. Funny brain, funny world, and funny straws.
