    Stare up at your own ceiling starscape

    Arduino Team — June 15th, 2020

    Have you ever looked up at your ceiling and wondered how to make it a bit more interesting? Well, creator Centas has and decided to bring a piece of the galaxy into his room using a fiber optic star display.

    The installation is powered by an Arduino Mega, and features approximately 1,200 points of light along with sound-reactive LED strips around the perimeter.

    User interface is handled by a second Arduino and a pair of nRF24L01 transceivers, while PCA9685 boards are implemented to control LED brightness levels. The system can even pulse with music, thanks to an MSQ7EQ chip.

    You can see it in action in the video below and find more images over on Imgur. Note that the constellation lines were added in video production for clarity.

    Wall-mounted world map shines brightly with fiber optics

    Arduino Team — October 23rd, 2019

    Apparently not content with looking at a map in a book or on a computer screen, YouTuber ShareAHack.com decided to CNC cut and mount a projection of the world onto his apartment’s wall! 

    The build was completed in sections and pieced together to form the model, with moss-covered land masses and cities represented by fiber optic LEDs.

    Illumination is provided by a series of LED units, which combine white and yellow light that is transmitted to small drilled-out holes via a large number of fiber optic strands. An Arduino controls the lighting via N-channel MOSFETs, allowing it to randomly vary the output for a pleasing and realistic effect. 

    Files for the project are available here, though be warned that it took around six months to finish!
