His landmark invention came after WWII ended. While on vacation, Land’s three year old daughter asked him why she couldn’t see a photo he had taken of her right away. He tried to explain to her they still needed to be developed, but that didn’t comfort her.
So Land went into the lab and created a system of one-step photography using the principle of diffusion transfer to reproduce the image recorded by the camera’s lens directly onto a photosensitive surface — which now functioned as both film and photo.
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.
