  • What chips did you use to latch/buffer the pic?

    I can see a few chips at the bottom of the board.

  • 4015 shift registers which feed ULN2003 transistor array IC's

  • What chips did you use to latch/buffer the pic?

    I can see a few rows of chips at the bottom of the board.

    I'm in the process of building my own as well.

  • This uses a PIC16F877, and is still work in progress not finished yet, i dont have any current limiting resistors feeding the led array at the moment which is why the display shows brighter but could lead to earlier failure of the PIC. Also dont have a complete schematic yet
