Just wanted to let you know what we do with the laser at DMS. This information can be found at http://dallasmakerspace.org/wiki/Laser
The laser we have at the space doesn't belong to the space, but to one of our members. We have an exhaust vent for it because it gets pretty stinky. Also, things tend to readily catch on fire while being lasered so we have a CO2 tank (from a paintball gun???) to squelch the fires.
1) Members must take a laser class before using the laser
2) Members must pay $5/hr (or partial hour) to use the laser
3) The computer that is hooked up to has a username/password that is only given to people that have taken the class.
Some talk has gone on to further restrict usage by RFID tag, but is pending on a local LDAP server. All our members get access to the premises via assigned RFID tag so we all have one already.
