Automatic Sunglasses For the Lazy Hacker | Hackaday
[Andreas] may have created the ultimate lazy hacker accessory: automatic sunglasses, or “Selfblending sunglasses” as he creatively titled his video. If you can’t tell from the name, these are glasses that you never have to take off. If the light is dim, they move away from your eyes. Going back outside to bright light? The glasses move to protect your eyes.

The glasses consist of a couple of micro servos which move tinted lenses toward or away from the user’s eyes. A side-mounted Arduino Uno reads a CdS cell light sensor and drives the servos. Why an Uno rather than a much more wearable Arduino Nano? It’s what [Andreas] had lying around.

Epaper holds an image even without power - Visionect
Epaper is different from other types of displays. Whereas LCDs, LEDs and plasmas will strike horror into the hearts of signage integrators by turning dark as soon as power to them is cut off, an electronic paper screen will hold the last image displayed even if disconnected from the electric grid or if its battery runs out
