Here's the video.https://res.cloudinary.com/engineering-com/video/upload/v1628039337/tips/IMG_0581_x74gqi.movhttps://files.engineering.com/getfile.aspx?folder=0b1f20a8-6a39-4826-9fc4-1ca90410d26b&file=IMG_0581.MOV

The solution turned out to be incredibly simple. I built a mockup with a simple carriage moving on a track, using wood and four plastic window hardware wheels from Home Depot. It took me a couple of tries. It needed a top section on the track to keep the moving piece from jumping off, since it...

I am looking for a way to control the speed at which a spring-loaded device returns to the original position. How this is supposed to work is that there are panels with graphics. A question is on the left, a photo in the middle, and an open space on the right. The photo is on a fixed panel...

Tokens.

This shot was taken from below. The yellow part is the arm that is forced down into the scalloped recesses of the wheel. The top left of that arm is the pivot.

Here's a look at the scalloped wheel in the back.

Here's the front. You can see the edges of the light blue colored wheel on both sides.

About two years ago I asked for help with a game unit I was doing for a museum application: https://www.eng-tips.com/viewthread.cfm?qid=454783#post This thread is now closed. Covid and other factors delayed the project but I eventually got it done. Here are the photos of the final unit I said...

"There is a second lever/slide that the user pushes to initially move the cam-lever out of the way and then its remaining movement sends the wheel spinning. " That's where I got it. The user just spins the 38" dia wheel. That's it. No other action on the part of the user. I did not design the...

There really can't be any other effort on the part of the visitor except spinning the wheel. So any secondary lever or foot pedal is out. In fact, everything has to be able to be used by someone with a closed fist. ADA standards. But I'm going to marinate in these ideas and let everyone know if...

Can you describe how that works? I believe I read that there were pins that go into holes in the rotating reels of older style mechanical slot machines. I guess that's like my spring loaded ball transfer idea.

Dave, your idea seems like a variation of the cam ides I posted, which the terrific addition of the door closer to allow the wheel to spin a bit before coming the arm brings it to rest. However, I am going to try the simpler solution first. My concerns with that are one, the precision of where...

IRstuff, I don't want to reinvent the wheel but from my observations the flapper on a wheel of fortune doesn't stop the disc very precisely. Sometimes the wheel bounces back a little. I have text on the wheel that needs to line up neatly with an opening in the front of the cabinet. Still, I'm...

Hello all! I am more of a designer than an engineer, and I joined this group to solicit ideas to solve a seemingly simple problem. I hope this is considered appropriate and I would appreciate anyone willing to help. I have been tasked with creating a game spinner device for an interactive...
