    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.

    I did the same thing using small 6 electrolitic caps which connected as parallel to base pin of driver transistor and ground path. But non adjustable for tail lighting effect.

    Good evening, I live in Rio de Janeiro, when would you charge me to make this LED bar, because I wanted to put it in my car?

      You have to make this yourself as the circuit diagram and testing has given in my video, called a DIY project.

      This is a DIY project designed by me which has tested on a dot board in this video. You can design and make your own PCB using a suitable software.

    What mounting LED you use?

    • @hobbyelectroniccircuits7391
      @hobbyelectroniccircuits7391  Před 5 měsíci

      I have used 12V LEDs. Alternatively you can use 5mm or 3mm LED segments made by connecting such four LEDs and a resistor (33 to 100 ohms) in series.

      BD139 තියෙන්නෙ වමේ ඉඳන් E C B විදියට.
      D313 තියෙන්නෙ B C E විදියට.

      @@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.
