Anyone can be a scientist, and this issue we’ll show you how. Whether you’re interested in space, traffic, the oceans, or something else, there’s a citizen science project for you. The world has never been more connected – so let’s use that connectivity to make our planet better!
We talk to a real-like scientist about the emotional links between making and materials
Turn empty drinks cans and a bit of 3D printing into a heat-exchange system for a laser cutter
Coax random numbers from a humble ESP32 board
Make music with a Raspberry Pi Pico
Build a glorious piece of retro tech in the shape of a crystal radio
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.
