    Jumbo Seven Segment PIC16F628A Clock ( Super accurate timing )

    This is the biggest clock that I have built yet. And this clocks hart is a PIC16F628A micro processor. The one second tick algorithm is similar to the one used by Roman Black. This clock is testing over 7 months now, still running it without an error.

    12Hrs LED clock ( Almost No Parts Very accurate timing )

    12Hrs LED clock ( Almost No Parts Very accurate timing ) The processor that I am using here is PIC16F628A. Im testing this clock for months now still no error. The one second tick algorithm is similar to the bresenham timing techniques. There are no resistors for displays because I limit the...

    8 x 64 LED Dot Matrix Sign board.

    Finally I built little bigger Dot Matrixs sign board. But still there is lot to improve. At the moment im working on character spacing algorithm. And also you can see the characters isn't go with the display. Thats because my character gen is for 5X7 displays not for 8X8. I hope to post here...

    HT1632 LED Display Driver successfully interfaced with PIC MCU

    Hi, finally yesterday night I interfaced HT1632 display driver with PIC16f628A. I really strugle a lot with this interface. Because Holtek1632 chip Data sheet does not contains that much literature. Anyway here is the first test. In here I use two 24 X 16 LED boards ( LED count 768 )...

    Processor Fan Blades pops out ! Dont do some thing like this stupid.

    This is one of my extremely crazy friend's CPU cooler fan. He said he directly aim the vacuum cleaner (JetForce 2200W vacuum) to processor area and try to brush off some dust. He said processor fan spin back words and sounds like turbine ( Its actually pretty fun to him even after what happend...

    Laser Diode Sony DVD Rw

    I very much like high power Lasers. I had old but working Sony DVD RW. I dismantle it for take out the laser Diode. Normally they are using High Power Lasers to Burn DVDs. Higher the Drive Writing Speed more stronger the Laser ( like 100mW to 250mW ). Coz of those High Power Lasers it can harm...
