[hackerspaces] Tips on making passport stamps?

[Jerry Isdale]

The various laser manufacturers and laser product suppliers all tout laser cutting/etching as a great way to make rubber stamps.
I've been thinking about doing some of these myself.  A quick google turned up articles like:
   http://www.rubberstamps.net/creating-rubber-stamps-1.aspx "the best technology to use is a laser engraver"
   http://www.laserbits.com/images/LaserResources/TechTipsandFeatureStories/FeatureStories/articles/marking_devices.html
   http://www.epiloglaser.com/sc_stamps.htm

The laserbits folks have a Sample Kit with parts to make 8 self inking stamps...

You could make one for the space and one for each member that contributed towards the kit.

Low tech approaches (cutting tools and wood blocks) can produce nice stamps too.
but you have a laser.... burn something!
