I've built my own do it yourself Black Bird Holdout. It works on the same principle but only uses cheap parts you can find almost anywhere. One bonus is it can hold more than one coin and release them one at a time. Also it doesn't care what kind of coin you are using, even quarters! I like to use it better than my Black Bird, but wonder if I should just keep it to myself as it does accomplish the same thing as the Black Bird. What do you guys think?

. Pm'd you.

Any photos?

I can upload a video of my performance. The moderators here have told me not to reveal any secrets however.

Here is my latest video jam session, like it or not!
