The project uses 940nm infrared (IR) LEDs embedded in clothes to overwhelm photo diodes in IR-sensitive cameras used for surveillance. Since the wavelength of the lights are not visible to humans ...
IR LEDs provide 35% higher brightness and 42% higher efficiency compared with the company’s existing technology.
The idea is simple — equip a standard hoodie with a ring of super-bright IR LEDs, and control them with an RP2040. We’ve seen blinding hoodies before, but here the LEDs strobe on and off in ...
Most light emitting diodes function in the near infrared and visible ranges ... Usually the larger the viewing angle, the less bright the LED. Diffused types generally have larger viewing angles and ...
