Hey everybody,

I know everybody's really excited about making their own thing, but here is
Hacker Dojo's open-sourced implemented solution to this problem. We've been
running it for a few months now, and it has been working pretty well.  I
figured I'd throw it out there.

Here's a writeup of the bill of parts and shows the schematics
http://katylevinson.com/blog/?p=7

Here's the code we use to run the maglock computer
https://github.com/hackerdojo/hd-maglock

Here's the code which handles signup, billing, and RFID assignment and
tracking https://github.com/hackerdojo/hd-signup, it also controls which
users have rights to RFID keys and which do not.

The relevant interfaces are as follows: the RFID reader is a simple USB
keyboard input, and the relay which controls the door is set by the
ready-to-send pin on an RS232 controller, schematic is included.  The
computer pulls the authorised membership list from the server via JSON.  The
membership accounts are just Google accounts for the @hackerdojo.com domain,
so we piggyback on all their security/user managament/administration
systems.  System tolerates network outages (of course new members authorised
while the network outage is going on won't be admitted), and tolerates a
building power failure of about 6 hours before intentionally failing open.
Emergency open button is a hard break, no computer in the loop, for fire
safety.  Entire system costs about $250 USD to make, and keys are about 60
cents.  System can be installed in a weekend.

We are excited to see what you all come up with, but I figured I would throw
this into the ring to let other teams look it over.  We really would
appreciate your feedback (or better yet, code patches!)

Thanks,
Katy

PS: This system also works with our login system,

take all our code, use it in your space, and submit many many bug patches
