lock idea to impede picking

[Father Time]

Behold one of the most popular physics toys of all time. It's been redesigned over the years, but the principle remains the same.

They're a real hoot to see in person.

for my science project last year, (9th grade) I conducted three experiments levitating magnets. The first was with diamagnetic graphite, a small cube of gold plated NdFeB, and a larger nickel plated magnet to lift it. The second was the gyroscopically stabilized effect, similar to the levitron. My third (and most fun) was the liquid nitrogen superconducting ceramic. I submerged the superconducting ceramic in liquid nitrogen (got it at the hospital, used for removing warts) then placed a small NeFeB magnet over it. The magnet induced a current in the ceramic, which has no electrical resistance, which in turn made an electromagnet out of the ceramic, thus pushing up the neodium magnet.

Needless to say, I won first prize

As for the magnets in the lock, the only magnets strong enough would be neodium-iron-boron earth magnets, but those are so brittle, they would likely break if anyone tried to bump it or rap it with a hammer

Good for you!

I used to win most of the science fairs when I was in school. However, growing up in a small Alabama town in the 60's and 70's, I didn't have access to such exotic materials.

I did manage to levitate a styrofoam bead between two charged metal plates.

Another project winner was a flame loudspeaker. You seed a blowtorch flame with certain salts to make it conductive. Then you put two electrodes in the flame that are hooked up to a high power amplifier. The flame will actually produce a decent sound.

I should have taken physics in school, but I'm a mathmatical idiot. Learned physics on my own, as I have alot of things.

God helps those who help themselves.

Good luck to you.

I am NOT an evil genius

I am not sure if I believe your tagline now

Holy crap you guys are are like wicked smart. I mean like scary smart. You know what my science project was, I built a flashlight. umm yeah so laf if you want but um yeah. Im a retard compared to you guys.

Hey, I find just about everyone has something they excel at. It usually depends on what interests them. On everything else, we all struggle a bit.

So my rule of thumb is, you can pretty much be good at anything you want, you just can't be good at everything you may want. Make a choice, make the effort and it will usually come.

This idea may not be as crazy as it sounds

If you had small magnets on the end of the drivers, you could use them to trigger a magnetic sensor to detect if the pins were being overlifted during a picking attempt (or bump key attack). The sensor could trigger some other action like an alarm or maybe actuate some blocking mechanism. I don't believe this has been done before, but now the idea is out in the open, it's too late to apply for a patent!

I don't believe in cursing a flower that has not yet opened.

You have an interest in picking locks. The greatest pleasure comes from an opened mind, picked open by possiblities yet undreamed.

GREAT!!! Now I can have the police called on me every time I put the wrong key in!!!!

Sorry about the late post on this, just catching up on the threads. This wouldn't work because if you had a shallower cut at the tip of the key it would push the deeper cuts up to high.

[d_goldsmith]

Not to mention that fact that pushing a key in fast, probably causes some bumping effect. Even really slowly putting it in though, the shallow cut at the tip would cause an issue.
