Tired of that smug look of satisfaction on your kid’s face when they’re able to find Waldo on a page faster than you can? A creative agency called RedPepper built a robot that levels the Where’s Waldo playing field using a camera and machine learning AI to spot the striped traveler in as little as four-and-a-half seconds. Looks like you’re out of a job, little Billy.
Once the robot arm is in place, it snaps a high-res photo of a two-page Where’s Waldo spread, and analyzes it for recognizable cartoon human faces using the OpenCV computer vision programming tools. To actually spot Waldo, the robot’s designers trained Google’s Cloud AutoML machine learning tool on a relatively small collection of 107 Waldo head and body images.
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.
