Ph.D. candidates in Mechanical Engineering, Pranay Jain and Anshul Singhal from the Massachusetts Institute of Technology, have invented Squirrel Devices to address this problem. Caliper tools were imprinted with Braille measurements so students with blind and low-vision (BLV) disability can effectively obtain dimensions and sizes of continuous geometrical shapes. This instrument is targeted for students at K-12 or secondary levels so they can keep up with their other peers.
The tactile caliper is precise to 1/16 of an inch and is four times finer than current rulers. One of these calipers cost between $18 to $29.95. Other units of measurements such as centimeters are currently unavailable in Squirrel Devices and the maximum length it can measure is 12 inches or less. Take a look at this video for a demonstration.
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.
