At a 2014 NMRA Division 3 meeting in the Lone Star Region, we had a Make and Take to build a "Decade Box" or "Resistance Substitution Box", as shown for sale here at Amazon, but with our own resistor values (2 sets ($3) linked to Digikeyor Mouser) to assist a little closer in the selection of the perfect resistor for your LED or Lamp on your railroad (100 Ohm to 4.7 kOhm). So, we needed a new face plate for the box and we asked the laser to help. Even with your own name on it!
Older fun projects with the Laser:
cutting a big Noah one in the back ground!
