We spent a few hours on friday fitting the maglock, embedding the RFID
reader in the door, and fixing the doorframe back to the door.
When we fired up the maglock to test it out, we found that the door can
twist enough that someone can probably get a crowbar in there and pop the
door open. So basically. we’re going to throw that idea away, it’d leave
the space way to insecure. While down in London for EMW, I had a look at
the London Hackspace doorbot system, which is pretty nice. It uses a
regular lock that is electrically overridable [
and was significantly cheaper than the ones we were looking at
before I bought the maglock, so we’ve bought one of them to fit on hack the
space evening this thursday.
To activate this lock, we need a 12v AC power supply. It needs to be about
2.5 amps, as the lock takes 1.6 amps to strike open. I also plan on
rectifying the rest to 5v DC to power the Alfred board and Raspberry Pi
that will do the RFID stuff.
Does anyone have anything suitable lying about?
