RFID system update + anyone got a 12v AC power supply

Google Groups
1

Hey List,

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 [
http://www.saundersonsecurity.co.uk/acatalog/Cisa_11610_Rim_Electric_Locks.html],
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?

Ta,
Bob

Found this in the transformers box…

Just what was requested.

I’ve left it on the table next to the door.

the same question would apply if you had a key to the door and you had left
them at home.

If you don’t have your key, there should be no way “around” the security.On Thu, May 16, 2013 at 3:19 PM, Bob Clough parag0n@ivixor.net wrote:

Theoretically I can SSH in remotely and open the door, but I’d rather not
if possible (as the door needs to be opened and closed to re-lock it)

Hi All,

Now Alfred is back on the door, is there a way of getting past him if you
have forgotten your RFID key?

Kind Regards

Hey List,

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

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?

As of last night, the external RFID reader has gone live!

This means that members should now be able to gain completely keyless
access to the space when the shutter is up. (Most days from 9am to midnight)

When the shutter is down, you still need a key to open it. These are £2
each available from me, and available to all members.

If you want your card added to the RFID system, scan it on the external
reader until you get a red light, and note the time and date. Send me an
email with the time and I’ll pull it from the logs and add it to both the
readers.

You will need a Mifare card, this should cover most rfid bus passes, oyster
cards, and visa / mastercard contactless payment cards. If you dont have
one of these, we have plain cards, stickers and keyfobs somewhere in the
space, I think they were £2 each.
