i meant that instead of using so many wires to connect, i would rather prefer to use a single pcb with etched patterns on it.
I was just trying to improve presentation.:)

thats everything on you.. you can make it as you want provided you keep the original circuit intact do share your finished hardare with us.. photos and vids

hey guys i having big problems.:(
i tried to make the propeller display again. But i am not getting output. When i connect supply to the circuit, i just get fast blinking leds, With no particular pattern. The new one i tried is on single pcb and a small one for the interrupter module on the other side.i will upload them soon. Please help guys.what should i do?

i tried to make the same project again. But i tried to make using single etched pcb. And mounting supply on board.
now i dont know whether or not interrupter is working or not during rotation. But when i tested the ckt it worked fine.

there is no particular pattern. The leds appear to be switching very fast and somewhat periodically. But when i rotate it, it seems as if all of them are on. ...:(
what should i do ?

are you testing it without rotation?? What is the RPM of motor you're using?

I dont think its the problem with PCB. All i am saying is.. there must be a small thing missing in the loop. try to run your motor a bit slow and see if you get something understandable and visible..
