A series of photos by The Guardian that shows an aerial view of the rental bikes removed by authorities in Chinese cities such as Beijing, Nanjing, Wuhan and Shanghai and the patterns they create. These shared bikes, which customers rent using their smartphones and can be dropped off anywhere, are considered a nuisance since they block pavements and apartment entrances. Inexperienced riders sometimes swerve into traffic and the bikes are often damaged, vandalized, or abandoned. Some of these bike share companies have gone bankrupt, leaving behind thousands of bikes that represent waste on an enormous scale.

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.
