We don’t have to wait for a dystopian future in which our faces are scanned as we walk down the sidewalk and our every movement is logged – we willingly carry personally identifiable tracking devices in our pockets everywhere we go, and cameras are everywhere. What’s the average law-abiding citizen concerned with privacy to do, let alone activists and protesters seeking to exercise their constitutional rights? These wearable counter-surveillance designs, including drone-evading cloaks, signal-blocking phone cases and fingerprint spoofers aim to provide us with privacy-preserving tools in the age of Big Brother.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
