Globalman Magnetic Lock

you done a good job there udanis.
so each magnet pulls the pin straight allowing it to pass through the holes in the locking system and releasing the shackle? cool

It actually just angles them, when you pull up on the shackle the light sliver arm at the bottom left pushes the locking system (superglued gold thing) to the right. If the pins are in the correct positions the locking system will slide right over the pins. Maybe this is what you were getting at.

yes thats what i was trying to say. its 1am and im half asleep but had to see what it was like inside that lock

Gotcha. The angle of the pins is what allows the lock to open. If you stuck a magnet the size of the key (in other words, if the whole key were magnetic) into the key cutout, the pins would be pulled against the body of the lock but the lock still wouldn't open because the pins would be at the wrong angle to facilitate the movement of the locking mechanism. The position of the magnet in the specific corner of the hexagon pulls the top of each pin to a specific point on the lock body orienting the length of each pin to the appropriate angle to allow the locking mechanism to move over them. An interesting idea.

Ok, here is a little video:

very clever device.

so, the obvious next question is how does one manipulate something without any tactile feedback?

i imagine that a small magnetic field is induced in the needles as they're alligned, so knowing the keymagnet locations would permit you to see with an accurate field monitoring device when a needle is alligned (not moved further when you test it) to achieve an "impression" of the keying, but wouldnt' a magnetic tipped needle with a non magnetic needle body prevent that from working?

The thing is you do have tactile feedback, if you pull the shackle slightly you can control how far the "locking bar" slides to the right. I have been able to get 3 out of the 4 pins into to locking bar.

There is a fairly simple bypass for these, which works nicely on my MagLock, fairly quickly. Dunno if I can post though, maybe if a mod ok's it.

You could also bulld a simple oscilating circuit, attached to a solenoid, with a rod coming out the end to use as a "wand"
