David, nice addition to your line of lighting products. It was wise that you informed the viewers about removing the data line, and, when a second power supply unit is used, to remove the power from the inline plug.
For power injection, do you need to run both a positive and negative wire from the power supply to the injection point? Or can you just run a positive line? If you have a negative running through the controller and through all the lights inline in that way wouldn't a negative line for each power injection be redundant and unnecessary?
Question. So if you had a meanwell 12v 350 watt power supply how many power injections can you do off of 1? I'm new to this and just started making props and building controller boxes and getting things together for a light show christmas 2023. I know distance makes a difference as I'd rather run a separate power supply 50 ft down than run 50ft of wire. But either I missed it or I'm confused as to how many power injections you can run off 1 or how you can calculate that?
If I power inject at the very end, from a different power supply that my controller is plugged into, how would I do it. In the video you take out a pin, but if I have item
Do you actually have to remove the pin? If the SPI output you're using doesn't have any data going down it, then it wouldn't cause any interference, right?
Honestly, I find these power injection Tees very expensive and a bit redundant. To power inject, one will need to bring the power through some wires, why not simply slice pixel wires and add a two pin connector (male & female) on both pixel and power wires and connect them up. This is what I have been doing for over three years of using 5v pixels only in my display.
If I'm Power injecting from a 2nd supply for the same string with multiple PI points, do i need to cut the V+ from all the tees? Or is the first cut on the first PI point good enough.
Thanks for this useful information, now i get how the power injection works.....

As always, very useful information. Thank you!

Question, stead of removing the positive pin from the PI cable when using a 2nd PSU, can I only connect the ground wire at the disto. board?

Is the pin removal a permanent modification? Or can the pin be re-attached later?
I’m confused on how to actually inject the power, how do I connect the tee to my power supply I don’t know all that wiring stuff
