It seems like they don't sell a kit to turn a regular pushbar into an
electric pushbar, so we'll have to get a new pushbar with the electric
option. They're a bit over $600:

We should probably just get their official bendy-cable to run the
power to it as well, since it's only $17:

The electronic pushbar requires 28 VDC. The official power supply is
crazy overpriced at $380:

Unfortunately we'll void the warranty on the pushbar if we use any
other power supply. I still think we should find a different 28 VDC
power supply.

That puts our total at around $700 including tax and shipping.
Installation should be free since George the landlord will have it
installed for us.

Then comes the computer hardware. Susan suggested a Beagle bone, which
costs about $80. We could add a wifi usb adapter to avoid running wire
to the door, and I'm sure we have those lying around. Then we need the
28 VDC power supply and a relay. The relay is close to free, but I
don't know where we'd get the 28 VDC power supply or how much that
will cost us. Any ideas?

Let's add another $50 for magnetic stripe card and/or rfid reader.
That'll be about $850 total, excluding the power supply (maybe we know
someone who has a 28-30 VDC power supply of some not-insignificant
amperage lying around?).

Now the question is: Do we just go ahead and order this stuff? Or does
anyone know anyone who might be able to get this done for less?
