This technique for creating high contrast panels for electronics projects and prototypes using a laser cutter gives great results using cheap and easy to find materials.
Here are some photos of some items made with a method using just 3mm white acrylic and a black wax crayon. It’s easy, fast (though not as fast as SureLase) and looks dead smart.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

If you intend to do more than one of these in your life, it’s worth investing in Lacquer-Stik fill crayons which are actually designed for this application. They are easier to use, the result is more durable and it doesn’t require a post-bake. For large filled areas, Hermes brand engravers enamel is ideal. Neither of these products is all that expensive. Cleanup time can be greatly reduced by lasering and applying the fill through a masking tape layer, then peeling it off with most of the excess.
Cool! I was thinking about doing something like this, but didn’t have much of an idea as to how to go about it. Stuff like is this one of the many reasons I love the adafruit blog.
