I did a bit of searching and didn't see anything specifically about this, so please pardon me if it has in fact been covered, or if this is the wrong place to be posting.
The local HEB has 30 light strings of various colors for $4.99, so I figured I'd get 2 sets, knowing full well they'd likely have the 60Hz flicker going on. I am knowledgeable enough about electronics to recognize most components, and I know how to solder and have repaired numerous devices over time. However, I do not know how to build a full wave rectifier nor did I know that that was what I needed, among other things, to fix the flicker issue. I merely knew that more expensive strings could be purchased which handled the flicker. Seeing as I am bored and have been itching to work with electronics, I opted to buy the cheap strands and do the work.
I posted on another forum I frequent about this and got some info with some links, but nothing really concrete. Looking at posts here, it would seem there are much more knowledgeable folks afoot.
What I am hoping is that someone here would know with a fair level of certainty, what components I would need to buy, and how to hook them up to build the rectifier and such to bring the flicker up to a level I cannot see it.
The strings are typical for LED xmas lights I presume, non polarized plug, 3A fast acting fuse for each blade, then the wiring going into the cathode of an LED and out the anode into two 620 Ohm 5% resistors in series, and then out to the remaining 29 LEDs, cathode to anode all the way to the tip, then back along the other wire to the plug again.
Without a multimeter or something there isn't much more info I can provide at this point. I am hoping this is enough info to get some kind of an idea what would be safe to use to make these strands flicker free.
