I wanted to wire up a bunch of cheap multiple flashing LEDs (red-yellow-off, 3 seconds total cycle time) that I got off eBay but they aren't playing nice. If I run just 1 LED they work fine but if I put 2 or more in parallel (each with its own resistor), they start misbehaving and flashing only red (for about 1/10th of a second) then off. it did not matter if I used resistor on anode or cathode side. I am just guessing but these flashing LEDs seems noisy and causing interference? It'd seem silly (and messy) if I have to add 100 capacitors parallel to each LEDs just to cancel out each other's interference.
Is there a way to wire up some 100 of these as I wanted to put it inside my computer and make it look like that old computer with lots of flashing lights from old sci-fi show. (More specifically I wanted the WOPR display LED from the movie War Games)
Available rail are 12v and 5v. As a last resort, I could also use 2 resistors one on each side of LED with a cap parallel across LED.
