I'm not in the area yet (will be starting next week), nor am I a member (hell, I've only been once or twice before because the only time I'm in SF for work with archive.org [I'll be in the area for a lot longer this time]), but I'd love to help anyone who is working on this, or pick up the current state and play with it myself.
I set up a similar system in a hackspace (more of a physical toolshop) that would announce when things went out the door, and even what the item was with espeak.
Anyway, RFID is fun and I enjoy playing with it. :D
Not sure what sort of procedure/permissions I need to go through to work on such an infrastructure project, though; definitely don't want to overstep my bounds or break any rules as a fledgling NBer.

If it can be made to work properly, we can put RFID tags in any items we want (private or public) and program our computer systems to react if and when those items go near or through the door (or elevator room). This could be useful in deterring or preventing theft, so that Noisebridge CAN Have Nice Things.

The only way we can expect this to stay that way for long will be to tag tools with RFID tags, so that if someone tries to exit Noisebridge with something, everyone in the space is immediately alerted to the fact and the items can be recovered, and the attemped theif deleted.

> Brandon started the project awhile ago, by reading the CHUMP manual and writing some C code. It should be done in Python. Basically, read the serial port (on minotaur) and ignore when it repeats itself. Send CHUMP commands and see if you can get it to tell you the serial number of the RFID tag that's taped to it.
> If you look at the serial port now you will just see the same line repeating over and over. It does not contain the data we're looking for. If i take a different tag over there (instead of the one that's there) it says the same thing. Not very useful. We need to know WHAT is passing through the door in order to know what to do about it.
