LV1′s Hackerspace Passport Stamp

Last night I made LVL1′s hackerspace passport using our Full Spectrum Engineering laser. It really was not that difficult. I used Chris Cprek’s LVL1 logo image for the stamp. It is the Plenary Gear logo at the top left of this page.

I used laserable rubber for this project. Even though it is low-odor you can still smell it. It smells like burning rubber from a car.

To laser the image, I took the original image and made it black and white. I removed the blue background and cleaned it up a bit using Gimp. I then imported it into Inkscape where I mirrored the image. The letters have to be in mirror image or it will not stamp correctly. Next, I ‘printed’ to the laser cutter. The Full Spectrum Engineering interface to driving the laser is pretty darned good. If you are reading this post and do not have a laser, check out Full Spectrum, they are a real good value for your money and highly recommended.

I also cut a wooden back for the rubber out of some 1/8″ baltic birch plywood scrap I had laying around. I used double stick tape to tape the rubber onto the plywood backing. Easy. Finally I hot melt glued a handle onto the stamp. Interestingly, the handle came from the Louisville Slugger Museum and it is a scrap from when a baseball bat is cut out on their lathe.

I used a stamp pad from office depot which worked well and Jon was able to stamp his passport for the first time! I also made another stamp with the Lady Ada graphic from Adafruit. That also came out well.

    Should the larger stamps be curved like -) so the pressure per square inch is better than a flat stamp -] and applied with a rolling action.

    Still I like the growth of laser etched stamps.

  2. Awesome, it’s cool to see the local hackerspace featured on the blog.
