Step #1:

Arduino GRANDE
  • This is the Arduino GRANDE. It acts like an oversized, fully functional Arduino, but it is actually a shield of sorts.
  • Wiring an actual Arduino board to the GRAND allows you to demonstrate Arduino programing and use on a much larger scale.

Step #2:

  • Vector cut and raster etch the board file onto 5mm acrylic using a laser cutter.
  • The files were created with Rhino, but can be printed with any laser cutter software that accepts common file formats.
  • Test speed and power settings to get a good, clean cut and neat etching.

  • Cut the headers, USB, and power jack parts out of 6mm acrylic.
  • Test fit them together.

  • Fill in the etching with white acrylic craft paint.
  • You can wipe off any excess from the smooth board surface, or do extra clean up with rubbing alcohol.
