    Coherent light saves the day, lost keys returned

      Howdy,

       

      Here's yet another reason to join a hackerspace that has a laser cutter - you can etch a QR code to help ensure your lost keys are returned safely:

       

      A QR Code That Returns Your Keys

      Once the code was generated, I etched the acrylic on our laser cutter, going over the etching twice for extra depth, and filled the recessed areas with polymer clay [you can use fimo, sculpey, etc.], put it in the oven to set and covered with a clear layer of nail polish for added protection.
