I engineered something today! Nothing fancy though. I was searching for a way to be able to make the z-axes of the 3d geoboard movable. For this to work, I had to separate the switches from their connections to power, ground, and the arduino, while making sure that whatever position they ended up in would display correctly on the computer. Turns out I could hook them in parallel (I think) using just 1 line back to power, and then separating the ground lines back to the breadboard, keeping the logic line and the resistor there. Add some conductive tape and some scrapwood, and voila!
Here’s a couple of pics (pardon the general ugliness and messy breadboarding) and a screenshot of the Processing sketch display:
