A company called Second Sight is changing human vision by making prosthesis for eyes. They are working on FDA approval for a new bionic eye called the Orion I which does not require a retinal interface. Second Sight has a shipping bionic eye called the Argus II which required some retinal functionality to work. Both versions seem bulky, require surgery and provides very low resolution images. One user who has been blind for ten years says “It’s crude, but it’s significant, it will work”.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
