This one took a long time 🙂
Plinko board itself was fairly easy. Slick, whiteboard backer with some spare roofing nails I had laying around. “Reclaimed” wood from slats of an old bed frame. Pucks were cut out on a jigsaw, then sanded round. Fishing line and an extra shower curtain ring for the pulling mechanism.
Almost the whole thing was made from things I had laying around the house.
One thing I was actually proud of myself for, was creating the rotating arm / dropper apparatus. This was my first project that used a pulley system (I’m not sure if that’s what it would officially be called) that operates the arm when the handle is turned. The mechanism was made with a used bike tire tube I cut up to make the bands.
After rotating the arm, the plastic ring is pulled, which pulls the fishing line that runs up to the top of the arm via drip irrigation tubing I had.
The fishing line then pulls on a small wooden piece that rocks back and forth. I should illustrate this at some point to describe how it works, but basically, as it rocks backwards, it releases a puck while simultaneously holding the next puck in place (so two pucks don’t drop at the same time).
That took me a while to figure out, but I was pretty happy with myself when I got it to work.
Here’s how it looks in action
…and some photos from the process.
