How should Ben continue building his automatic can crusher? Post your idea + you might get a free Ben Heck t-shirt!

Ben Heck needs your help! In the latest episode he explores different ways to build a solenoid-powered automatic can crusher. They're looking for your suggestions on different ways to build and power the can crusher. Post your suggestions here for a chance to win a Ben Heck Show t-shirt! Ten submissions will be randomly selected after Oct. 24.

Just post a reply to this thread with your ideas, and you'll be automatically enrolled in the t-shirt giveaway.

We're looking forward to your suggestions!

Cheers,
Sagar

He should stick with the original solenoid idea, but he needs a better connection than that loose wire. Perhaps use an SCR/Thyristor http://www.newark.com/vishay-formerly-i-r/180rki80pbf/thyristor-285a-800v-to-93/dp/98K6039with a fast-acting switch to trigger it. All that sparking you see means the system isn't ideal for a high cycle life. Also, the rod should have very tight clearance through the center of the coil, and be solid. That should maximize your flux coupling without much leakage.
