Small LED dot matrix development board

I was very busy for the past two months so this blog just didn't move. As you may know, the LED dot matrix display is my favorite device. I have designed a small development board for testing my led dot matrix related programs.
The schematic is as the following:



The PCB is single sided so I can make it at home. Most of the components are SMD to keep small footprint of the board. The PCB size: 58.4mm x 46mm



Acutally, I made a PCB and installed all components but the board didn't work :p. It was working when I tested the schematic on breadboard (with through hole version of PIC16F887). I think the SMD PIC16F887 may be broken or the PCB is bad but I just don't have time to figure out the problem. I will try new PCB and PIC16F887.

AVR Rotating Led Display

If you like Rotating LED Display project, check out Rotating Led Display project by Aki Korhonen. He made POV project using modified 8 cm fan and microcontroller AVR AT mega as main part. To control the led, the project use 74HC595D shift registers. Not only can display the text this Rotating Led display can also demonstrate drawing and playable Pong game. Check the video below,

PIC Cactus LED Display

LEDactus is LED display project that resemble Cactus. It used PIC microcontroller 18F1320 as controller of the LED. LEDactus is immobile and attempts to survive by creating a pleasant display. It can produce more complex and mesmerizing displays. And in the latest generations, a sense of touch is added to allow the LEDactus to interact with passersby.
