Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLK Day, shipping could be delayed. Please allow extra time for your order to ship!
Cities contain miles and miles of elevated infrastructure: bridges, elevated train tracks, swooping highway ramps. They support thousands of commuters, tourists, and others traveling through the city. Beneath them stretch miles and miles of urban underpasses that are empty, dangerous, and virtually unusable.
The best ways to clean up and make use of these spaces is an issue urban planners and architects in cities worldwide have sought to address, with efforts that include making underpasses well-lit and building parks in the unused space. They might take note of the work of self-taught furniture designer Fernando Abellanas, who has transformed the underside of a bridge in Valencia, Spain, into an ingenious, pop-up workspace. Abellanas’s design is half floating studio, half horizontal elevator: One part is a metal and plywood box that moves across the underside of the bridge on wheels. When it gets to the far side, a shelf, chair, and desk bolted into the wall fit into the structure to complete the studio.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
