Another Opensource safe cracker

Looks like these things are getting more and more advanced.  This one can crack a sentry safe in 15 minutes (73 worst case).

A simple clamp rack

I have looked at some of the other clamp holder builds, this is pretty much the easiest one yet.  You just get pipe, elbows, and flanges and you have a rack.

This could be one way to simplify a keychain

Basically cut the heads off the keys and put them in line with a bike chain.  Interesting idea.

OK this is pretty funny

The author built a simple robot that climbs up a rope, and then cuts the line.

Oh and falls down to the ground too.
