A gutted credit card reader is repurposed to become another instrument for the Alpha-Bit arsenal. All the circuitry has been removed except for the magnetic stripe reader; in its place an amplifier and a speaker have been housed in the enclosure. Slide your credit card (or any card with a magnetic stripe) and hear the data information translated onto audio. Producing sounds similar to a scratching record player, the scratch box is a fun and expressive instrument. A 1/4″ output is included (as always) so that the fun can be made even louder when plugged into an amplifier.
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.
