Case #84: Ed Had A Fondness for Orange Crush
By Design News Staff -- Design News, May 14, 2006
For the gadget freak who thinks he has everything, here's Ed Nauman's microprocessor-controlled, pneumatic-actuated can crusher. Great for parties, it consists of a pneumatic ram, precision bore crushing cylinder with aluminum crushing piston, two pneumatic rams to control the loading of cans, and solenoid valves to control the rams.
Operationally, the user simply loads the cans into the magazine, opens the pneumatic ball valve to charge the surge tank, places the rotary mode switch in either auto or manual, and presses the run switch. In full auto mode, the crusher loads and crushes cans at the blinding rate of 1.5 cans/second. That's a lot of six packs!
