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?

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:

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.

Hi Jake and Marc,
I wanted to spearhead keycard access for the new omni office
(ex-'treatmenent room', near TIL.) Plumbing improvements are scheduled for
CCL, and Phat Beets will need to revamp to the Omni office temporarily
while concrete saws have at it in their current office, in order to
connectbup CCL's drain.
How might we best go about adding keycard access to another room, and how
can I help? I am happy to order and install as much as I can, as long as I
have a shopping list.
