the recycled island foundation is a young organization whose aim is the retrieval of debris found in rivers and river mouths and the sustainable re-use of these plastics, illustrated in rotterdam’s prototype floating park. ‘when we retrieve the plastics directly in our cities and ports we actively prevent the further growth of the plastic soup in our seas and oceans,’ explains the foundation’s initiator, ramon knoester, ‘the realization of the building blocks in recycled plastics is an important step towards a litter free river.’ in order to collect debris, the foundation developed three passive litter traps which were tested, monitored and optimized for a trail period of 1,5 year. the litter traps are able to capture plastics by using the existing stream of the river, and keep them trapped even when the direction of the stream changes.

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.
