Smokescreen is an open source application written in Processing for generating text that is unrecognizable for the most common Optical Character Recognition (OCR) software. The application generates random “pixels” overlaid text, confusing the software but not the human readers.
…in other words, randomly generated pixels are not going to prevent your boyfriend/girlfriend/cat/dog/significant other from reading the rant you’ve foolishly left open on your screen, but if someone is scanning your e-mails externally, you can use this to block them.
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.
