One of my hobbies is woodworking and another is piddling around with magnets. I found a toy/mechanism on YouTube that I'm building a gizmo of my own like. Below is that video... Here is my modified design for the V-Gate using a single stater. It’s a bit sturdier than the original. I haven’t had time to build one yet, but hope to before the summer is over. Below are the plans. I'm still fine tuning them.
