People delivering access to affordable care in developing nations always serve as friendly reminder that our devices can be so much more than distracting casual gaming platforms. Eye examinations are one of the clearest applications on that front — around three years ago, MIT’s Media Lab introduced us to a $2 box that could transform handsets into a mobile eye clinic.
Peek offers much of the same, albeit without the need for a (relatively) bulky add-on. Developed by members of the International Center for Eye Health, the app can conduct visual acuity, color vision tests, among several others.
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.
