8×16 ping-pong ball LED matrix display
Exapod built a 8×16 ping-pong ball LED matrix display. The ping-pong balls are used as diffusers for green LEDs. Two MAX7219 8bit serial LED drivers control the lights. A PIC18F2553 drives the MAX chips with text received over a Bluetooth module.
I finally finished my 8×16 ping pong ball matrix display, soldering all the boards, the leds, the wires and gluing the ball took me a lot of time. It uses a pic18f2553 to control two max7219, the string to display is sent via bluetooth.
Check out a video of it in action below.
