    Thats trailing effect. Definitely one of the better led scanners. And I have seen some really bad ones out there.

      Thank you..
      This circuit uses a simple capacitor charging/discharging method for the base pin of each output transistor.

    Can i use other npn transistor for this circuit? Could bc 547 work as well?

    • @hobbyelectroniccircuits7391
      @hobbyelectroniccircuits7391  หลายเดือนก่อน

      Each these 12V LED strips draw 100 to 150mA of current. The maximum current of BC547 is 100mA and not enough. Also the pin configuration of BC547 is different compared to BD139. So it is not a good replacement.
      You can use BD135, BD137, D400, C2383 to replace BD139.

      Not a clue, bought off internet.. a line of colour changing led’s to a box and wires… I was going to fit to car but wanted to add a rocker switch inside because it has a habit of turning on and off course it’s illegal to ride with lights on…

      @@hobbyelectroniccircuits7391 Thanks. It took me 2 1/2 years to make the software, PCB Maker, by NewRAD. And then about 35 minutes to mill the board with my CNC machine. But I did it for about $2. PCB Way wanted to charge me $48 for a board that big, and take 3 to 7 days. To do it in 35 minutes for $2, and with the added benefit of not having to use their software, or upload Gerber files, or use their website. To avoid all of that mess is priceless.
