As I’ve said previously we are currently working on developing a signal-split device: that is, we want something that takes one input and creates a copy of it. Or in other words one marble in, two marbles out. Below is the design we settled on for our first physical prototype of the signal split toggle.

We cut one out and mounted it. Here is video of it at work.

It works pretty well! It’s not perfect, we’ll have to keep working on it. The tough part at this point is that we don’t know whether faults in our prototypes are due to faulty craftsmanship or faulty design. We will have to make several prototypes and carefully observe them in operation to figure this out. My lack of any schooling or experience in engineering and woodworking is becoming a hindrance at this point.
