“This is a simple and cool moodlight project with IR remote controller that I’ve made starting from a salvaged lens out of a scan bed of an old HP scanner. This lens is capable to redirect a puntiform light source, uniformly along a wide surface; from here the idea to couple it to an Adafruit Neopixel LED to obtain a colorful 20cm long light source. Then I’v designed a 3D printed enclosure to support the lens and to accomodate the LED, the microprocessor and the IR receeiver. For the initial test I’ve used an Arduino Nano that is more than enough for the purpose; the final version will probably use Attiny85.”
