So last night at open lab I disassembled the current locking mechanics and made sure everything would work when buying a regular mortise cylinder core from Medeco. Everything looks good to go, I think I'm going to use the existing backplate which should be fine as long as we get a tail on our new core. The door knob and internals are still really flaky, but they really aren't even necessary at this point. With the new core, (Medeco 10 series) we will have sufficient security and it will be 100x better than our current locks. -Q

Last night, we started looking at the door in question, realized that it only had a handle-lock on it, and realized that we're going to need a wholly new locking mechanism to do anything useful/secure with -- so that's going to be project #1 in terms of serious implementation.

Last night, we started looking at the door in question, realized that it only had a handle-lock on it, and realized that we're going to need a wholly new locking mechanism to do anything useful/secure with -- so that's going to be project #1 in terms of serious implementation.

Elliot demo'ed his knock-code routine and got some useful feedback. Things like ambient noise and a relatively-long timeout period need improvement.

Andrew suggested using a "Sonic Screwdriver" a la Doctor Who. This opens up all sorts of fun/funny code mechanisms. For instance, a keyfob with an ultrasonic speaker might be sweet. Or use LEDs and blink out a code string into a light sensor. And like the RFID scheme, we could have individual keys for individual peoples.


Thoughts: Smart cards can offer some nice crypto, but they'd require the purchase of additional hardware (a kit) and are more expensive than RFID (around $2.50)

Another idea I had, and kinda like, is to have a computer connected to the internet and a SIP provider (as noted repeatedly, you can get free inbound calls via Google GrandCentral). When a call is received, it could listen for an access code (prepend a few digits for user id if desired) --NikolasCo 09:27, 28 May 2008 (UTC)
