Seeing these examples reminded us of another “classic” method of making halftones:ASCII art. In what follows, we walk through the process of using making CNC halftones for engraving or carving from both vintage and automatically generated ASCII art.
Seldom seen nowadays, ASCII art is a computer graphics technique where grayscale photos or artwork are represented by keyboard characters on a regularly spaced grid. And while it does show up occasionally in the history of computer graphics, it is perhaps more important as a cultural artifact of the BBS era of computer networking.
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.
