Each page of the Hackerspace Passport can accommodate 4 stamps of 41mm x 47mm, or 1 stamp up to 89mm x 118mm.<br> <BR><div><hr id="stopSpelling">From: grayje@uw.edu<br>Date: Sun, 31 Jul 2011 18:04:14 -0700<br>To: discuss@lists.hackerspaces.org<br>Subject: Re: [hackerspaces] Hackerspace Passports<br><br>What are we talking, about 4cm x 4cm for the stamps? Larger?<br><br>If anyone needs a stamp made up quick, I've used <a href="http://rubberstamps.net" target="_blank">rubberstamps.net</a> a few times in the past. They use a 1000 DPI laser engraver. Small shop, great service, fast turnaround, lots of options.<br>
<br>Also, QR codes don't work well. The problem is the ink - voids and inconsistencies when you stamp will usually confound the computer vision. So if you want a URL, use text.<br><br>James Gray<br>
