A DIY Project Features a 6-inch Square Blinky Light Setup with 25 Strands of Pixels Using a combination of high-tech components and creative 3D printing skills, one maker has developed an impressive 6-inch square blinky light display. The system is powered by a 25-strand array of 2801 pixels, paired with an HC-SR04 ultrasound distance sensor and a Teensy microcontroller board. To bring the entire setup together, the creator turned to 3D printing for various parts. Check out a short video showing off the blinky lights in action here: https://www.youtube.com/watch?v=QLblRXmSe3s Assembly Instructions The key to this project is getting all of the right components and pieces to come together smoothly. According to the maker, printing the 5x5-lenses file with white PLA produces the best results. For the other printed parts, including a back plate, four corner supports, four side frames, an LED mounting bracket, and a single lens, any color will do, as these components are designed to be discreet once installed. To put everything together, super glue was used for assembly, along with trauma shears for cutting slots in the backing plates to accommodate wiring. In addition to these printed pieces, an HC-SR04 ultrasound distance sensor is attached via a custom mount found elsewhere and glued directly onto the top of the panel. With all components ready, it's time to move on to the electronics. Running the show behind the scenes is a Teensy 2.0 board, loaded up with Arduino code available on GitHub here: https://github.com/bobiam/_5x5_ultra. It takes some careful wiring and separate power lines for both the LEDs and Teensy, but all connections should be straightforward if followed carefully. Want to take a stab at building this yourself?
