Hi David,
the electric strike needs to be installed into the door you want it to control.
fortunately these things tend to work with regular doorknobs, and the doorknob still works
normally, but you'll probably have to hog some wood out of the door jamb to put in the
electric strike.
you can test the strike with a random 12v battery (even a drill battery) to see if you
have it installed in a way that will work. there is no worry about plus/minus polarity.
I will try to get the RFID and/or magstripe stuff working as soon as i get a chance -
hopefully someone with more software skills will help once i get the hardware working.

Thanks for coordinating this Jake -- for this project,
I can generally make
myself available to help in a semi-unskilled manner either:
- late evenings Tu-Th (after 9p) or
- early mornings M-F (before 9:30a)
My weekends are generally tied up unfo -
I can do:
- physical installs, wiring / low-voltage electrical, basic carpentry
- software installs, basic dba & scripting, debug
Programming node tho, I'm pretty inexperienced but avail to assist
If you are there late Tuesday I can stop by. I could install one of the
electronic throws, for example? Or anything I can do - just point me in the
right direction.
Best,
David

OK so these RFID modules (and electric door
strikes) have arrived and now
it's time to wire them up and get them working as door access controls.
Ideally we will have them also do magstripe access since we're already
sortof doing that for a lot of people, we should probably support both
rather than forcing people to migrate one way or the other...

what hardware should we use as the "computer" behind each of these doors?
It should be able to talk to these RFID readers, as well as a magstripe
reader ideally. More beaglebone blacks or something else?
I wish we could use an openWRT router for door access computers, but there
is no way node is going to run on them as you can see here:
https://wiki.openwrt.org/doc/howto/nodejs
maybe these doors (other than the front door) can be openWRT nodes which
communicate to the front door computer for authentication, and that way all
they need to do is host their RFID/magstripe reader?
who realistically has time and is able to help me make this happen?

of magnetic stripe cards,
in which case we need to carefully choose a good RFID reader of the right
kind.
fortunately this has basically already been done at Noisebridge to some
extent, as seen in this repository:
https://github.com/noisebridge/rfid-access-control
the hardware they chose is seen here:
https://github.com/noisebridge/rfid-access-control/blob/master/software/fir…
tragically, their high-level software is in go:
https://github.com/noisebridge/rfid-access-control/tree/master/software/earl
so we'll probably continue using doorjam, which is in node and has been
working well enough for a while now on the front door, and i'm able to
maintain that.
i guess the only question is, do we make the new door use RFID tags
only, and
add an RFID reader to the front door, and then
gradually phase out RFID?
and that giant box of RFID watches that we have... do they work on these
types of readers? that's something we need to find out.
basically, you should order a couple of these:
http://www.ebay.com/itm/Mifare-RC522-Card-Read-Antenna-RF-Module-RFID-Reade…
and we will start playing with it to make something work.
In the meantime, we already have at least two electrically-operated door
strikes, that look SORT OF like this:

you can install one in the door you're talking about and get it working
physically, and then we'll be much closer to finishing the whole job.
