    RGB string problems

    After the first night (last weekend), when we had that heavy rain here, I did the rice thing (no heat source), and it worked, but then there was another heavy rain I didn't know was coming, and that's when one of them seemed did the 3/5 white thing. Then another lighter rain, and both were...

    RGB string problems

    More rain caused both of them to fritz out, but then the one that was good before started working right again, and other other one is just doing different things sometimes all white, then it seems random colors, I noticed, if I tap the controller, then it will change. What silicon coating are...

    RGB string problems

    This is the whole thing right here: JST connectors, three wire string, which IIRC is the 2812. Where would the shorting of the colors occur? the pins in the connector? (tries cleaning those). I looked closely at the modules, and they do look watertight. Again, I swapped controllers, and the...

    RGB string problems

    I've gotten two of those "chain letter drive" strings, that have the 3 LED modules made to light sign letters, but all the corner stores are now using them to basically replace neon tubes in the windows. The ones I got are 2811-2 "smart" strings (each module has its own address). It said they...

    WS2812 Hookup help

    OK, thanks! (It's actually not a strip, but a string of individual 5050's with the soldered wires visible on the back of the PCB. Like this basically: https://cdn-learn.adafruit.com/assets/assets/000/026/068/medium640/led_pixels_brain-cap-08.jpg No mounting; just hanging from suction cups on the...

    WS2812 Hookup help

    OK, thank you very much. I also wonder if there's any danger of having pixels with bare solder metal (for each of the three wires) in the rear in a metal window, and then if they can create sparks if the backs of the pixels touch that or each other (I didn't know they were like this when I...

    WS2812 Hookup help

    Finally, SUCCESS! I found a simple 5V 2812 controller at Tinkersphere (where I had already been going to get controllers and connectors, but didn't think to see if they had controllers, but at that point, I wasn't going to buy a new one anyway, still trying to get the TS1000 to work. Figuring I...

    WS2812 Hookup help

    You mean the SZMiniLED (Which is the most common one I see in the store window lights, which is silver-grey with the four black buttons and 4 digit 7-part LED display)? If so, I guess that's what I should have just gotten, but I thought the SD card would be better to have (and there's a version...

    WS2812 Hookup help

    Update, I decided to replace the clear house plug wire that I got from one hardware store. I now used a thinner wire with a solid copper strand, so it would fit in the GND ports with the other connecting wires. Now it looks like the controller is working right; only the power light stays on...

    WS2812 Hookup help

    OK; I just tried again, and nothing, no controller error or power light either. But when I took the [blank; never programmed] SD card out, then some sections of about 4 or so lights on both strings came on (green, cyan and a couple yellow, static). So obviously, this has something to do with...

    WS2812 Hookup help

    Tried again, to make sure the power supply was alive (it has an LED indicator), and hooking it to the consist, I got a very brief flicker from it looked like the whole string! Still, neither of the lights on the controller, though. Now some are saying it doesn't work without a program on the...

    WS2812 Hookup help

    I hooked it up like this now (with the wire connecting the two GND ports, and the power supply and LED wires in the associated ports), but nothing. I did once see both of the controller lights come on, but haven't since that second post. It's like the whole thing is completely dead. I don't know...

    WS2812 Hookup help

    I took the 12V out of it, and only using the one 5V now. Still, it's the wall adapter version. By “signal” GND, do you mean the GND port on the right side (next to DAT? There are two GND ports, and the other one is next to the power input. Some images, they have all the ground hooked up together).

    WS2812 Hookup help

    OK, how exactly should the GND be hooked up, then? I see diagrams or pictures with it hooked up to all four points (LED's, power supply, and both GND ports on the controller), and some where the power supply connects only to one GND, while the LED's connect to the other.

    WS2812 Hookup help

    Update, playing around with it, I could get either the indicator lights on the controller to come on, OR a handful of LED's, which would stay one fixed color. LAst few tries, nothing. So now, I've contacted the Amazon seller of the controller, and he referred me to someone else, and the person...
