The age of cheap, plentiful sensors, tracking everything from heartrates to the noise pollution slowly driving everybody insane is here. Joe Saavedra’s modular neuroid is a wearable, reconfigurable sensor system that monitors pollution we probably don’t wanna know about.The modular part of the system is that it works with different kinds of sensors. Currently there are working sensors for methane, liquid petroleum, light and sound pollution, and carbon monoxide. The flagship device, built with an Arduino + Adafruit GPS system and three connection points for sensors, is a little bulky—more of a bag-hanger than a pocketable unit, but it’s easy to see how it’ll be miniaturized over time. It pairs up pretty nicely with a Nokia N900
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
