These are absolutely fantastic – and show what is possible when you take advantage of a technique typically used for one process, and apply it to another. In this case ‘drawing’ on PCB layers and turning them into works of visual art:
I developed a process to convert color bitmap image files (PNG, PSD, etc) to files suitable for PCB manufacturers. David “Doz” Herman designed a number of pieces to see how various effects work, and I think there are some interesting possibilities.
These are all 2×2 squares, but anything that can be produced at a normal PCB manufacturer is possible. These were made at @oshpark and came out exactly as expected.
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.
