The useless box

I do a lot of useless things in a month. This box would be perfect to get them all done. As soon as you flick the switch it opens just enough
for a little arm to push the switch back

Does it use a Propeller or a BS2?

Add some blinking LEDs and a some speaker sounds to make it more interesting.
Does it open after a set time or does the time change?

People love 'em. Easily done without any processor or electronics, but I've seen people put an Arduino in them. Hard to believe many sell for $90: http://www.ebay.com/itm/Black-Medium-Useless-Leave-Me-Alone-Machine-Box-/261101697406?pt=LH_DefaultDomain_0&hash=item3ccadfb97e

Here's one I made.

Time for a pet rock... low tech and no batteries required.

A decent rock might even be more useful. For cracking open nuts say.

This one has different speeds and moods/behaviors, very fun to watch. At least two servos/motors and a processor.

It amazes me that people would go to such effort and expend so much time to craft a nice box and all for their "useless box" project and then use a micro-controller to make it work when all you need is a motor and a spring and a tiny bit of mechanism.

I had a very similar box back in the 1960's. It was a money box. You put a coin in a little slot on top of a black box. That would close a circuit that drove a motor that pushed a green plastic "Dracular hand" out of the lid, which grabbed the coin and started to retract. At that point the circuit was broken and a spring snapped the hand and your coin into the box.

Hey, and here it is: http://www.ebay.ca/itm/VINTAGE-DRACULA-039-S-BANK-MONEY-BOX-MADE-IN-JAPAN-battery-operated-tin-and-plastic-/321410025156

What really amazes me is that the economy of the world is being built on watching useless videos of useless machines... odd, very odd.

Get a life, go to a library. And quit pushing around electronics.
