I saw this project on instructables by system X. I tried to solder the components on a perforated circuit board but I couldn't get the solder to flow the way I wanted it too. Your PCB design helped me to complete this project. I couldn't have done it without your PCB design. Greetings from USA.

Hi Joseph. Great !! I see that you successfully did the project. I am trying to order the PCB. I went into the link above www.instructables.com/id/Make-Your-Own-LED-Matrix-/ and downloaded the Gerber zip file and attached it in the JLCPCB site but it is saying that "Detected 4 layer board of 102x152mm(4x6 inches)". But in the video I see that it is a 2 layer PCB. Do I need to remove some file from the zip file that is available in the link. Please help me. Thank you

Hey friend can you help me to make digital clock problem is only power supply, 1) First I purchased 2.5 inches(approximate) 7 segment display but it requires 9V for each segment and I was not able to use high side transistor switch, so I made my own segment display with 2 led for each segment and total of 2*7*4=56 LEDs, and they also not glowing as expected, now I'm working on 3rd experiment on bread board with total of 28 LEDs, one LED for each segment. So nearest 7 segment works with maximum brightness and decreases with distance, thanks in advance

You can add a simple PWM voltage regulator at Vcc
@ArneChristianRosenfeldt Місяць тому
You run a high frame rate and dither. I Wonder if it is possible to put a latch after the shift registers. Then per row you can load new versions of this row where more and more LEDs go dark. Then clock the latch ( without the latch would worry about EMI ). Shift registers are fast. You can probably do 8bit at this low resolution.
