Did you know?
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

3 way splitter for power injection

Recommended Posts

Hi, I purchased strands of 12mm WS2811 12v Pixels 100 count 4" spacing from Holiday-Light-Express. I also purchased their T Type splitters.

I was working on injecting power, but I just realized after getting odd results and finally testing with my meter, that these T Types don't pass all the wires through.

https://www.holiday-light-express.com/light_information.php?partnumb=RGB-T-pwrinj&stock_printout=63 in Stock

I'm guessing these are 13.5 mm connectors , all I know is the Holiday Coro connectors don't fit with them.

The layout of these T Splitters are

V+ flows from the Bottom of the T to the Left side of the T

V- flows through ALL connectors Left, Right and Bottom.

Data flows from the Left and Right. 

 

So two questions...

1. Does anyone know where I can find a style that matches this so that V+ and V- flow through the entire T and Data only flows from Left to Right?

2. Is something like this doesn't exit what is the best way to create my own waterproof connections? Do you guys solder and shrink wrap, or do you know of 3 way waterproof connectors?

 

Thanks for any help,

 

Steve

Steve, you don't want the V+ to flow through, it will just keep adding to the amp draw on your system and you will blow a fuse. You want the ground to flow through because you need to tie all your grounds together. 

See attached diagram of how these T work.

Here is a rough drawing of how I do my power injection for my DMX stuff

Thanks for sending that over! I had someone on another forum send me a link tonT splitters that would pass the entire 3 wires over.
Basically I did what your diagrams show. I only pass neutral throughout the entire connection. Positive only passes from the power supply feeding to the strands in powering. Data is passed through all the connections but never to the supplies.

Power injection is interesting to plan that’s for sure, but the results are worth it.



Have a Merry Christmas!
