Add extra-sensory powers to your toolkit with this nifty piece of HD Magnet Viewing Film. It’s a special film that contains a ferromagnetic slurry of ultra small nickel particles that turns black when around a magnetic field. Unlike some of the older films you may remember from grade school science class, this stuff is ‘high resolution’ so you can really see the details.
Slide it over enclosures and devices to locate hidden magnets and speakers. Comes laminated for protection.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
