The webcam’s public feed, like thousands of others like it, is accessible to anyone who can find its URL with a Google search. At an art gallery thousands of miles away, a tiny Raspberry Pi computer is streaming the video to a monitor while it analyzes the footage with a simple computer vision algorithm. It instantly snitches, flashing, “WOULD YOU LIKE TO REPORT THE JAYWALKER?” on the screen. If you’re a visitor at this gallery, you’ll face a choice: hit a red button in front of the computer, and it will send a screenshot of the incident in an email to the nearest police precinct, potentially costing her a $42 fine. Or you can let the oblivious lawbreaker go on her way.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
