Diabetic Retinopathy is a complication of diabetes causing damage to the retina, eventually leading to blindness. The cost of state of the art retinal imaging devices required for identifying this disorder lies in the range $10,000 – $25,000. This makes them inaccessible for the population in rural areas or developing countries. We aim to develop a device under $400 which can provide reasonable quality retinal images to clinicians.
The OIO uses a 20D lens, mirrors, light source and camera, a raspberry pi and a touch interface to achieve this. The lens and mirror system are used to compress the optical path and focus the light from retina onto the camera. The camera and pi act as the processing unit and display live images on the display allowing the clinician to easily image the retina.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
