    Welcome. FYI: You are not alone in Germany. I have a friend who lives in Germany doing both a halloween show and a Christmas show. It seems to be well received and he has a lighting party to kick off the Christmas season.

    Do not worry about asking questions. This is the place to ask.


    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show.

    Hello! My name is Mark and I live in New Jersey.

    My current setup consists of a Raspberry Pi 4 running FPP, a Falcon F16V3, power supply, router, and one 50-node string of WS2811 lights. I got xLights (I'm a Mac user, so Vixen isn't available for me) and just last night I got my first simple sequence running on the Pi and driving the lights!

    So now I'm planning my whole setup. I realize I probably don't have enough time to finish it this year, but I'm having so much fun I can't stop. I want to use strip lights because I want all my lights to line up in nice straight lines without any fuss. I want to line the entire length of my roofline with a continuous line of lights. I haven't measured it yet but I would estimate the roofline is about 75 feet long. It's my understanding that I'll probably run into power issues if one line is too long. I've read the phrase "power injection" to solve that problem, but I don't know what that actually means in practice. Can anyone point me to a good resource on the topic? Thanks!

    Welcome. Be careful with your desire to use strips. Some of us have had good experiences and some of us have not. I am in the 'not' column and have been replacing all of my 1:1 (WS2812+) strips with bullet nodes pushed through a mounting strip like the one you can get from Boscoyo. They keep the pixels nicely aligned and act as a guide wire for the whole assembly. My 3:1 strips are working well and I am keeping them in the show.

    As for power injection, it is a simple concept caused by pixel production costs. Wire can carry a finite amount of current before it has issues (voltage drop). The pixel manufacturers reduce costs by using smaller (lower current carrying capacity) less expensive wire. That means you need to correct this low power wire issue using better wire. Power injection is simply identifying points in your string of pixels at which the voltage has dropped below the minimum operating voltage of the pixel. At that point you take a fat wire from your PSU and splice it (inject power) into your pixels. The fat wire also has a limited capacity and over distance there are losses (voltage drop) so the choice of wire depends on the number of pixels the fat wire is driving and the distance from the PSU. The fatter the wire, the lower the losses (per foot) and the higher the current capacity. Fatter wire cost more per foot. FYI: These same issues drive the choice of location for your PSUs. Some people like a big central PSU others like distributed PSUs (I am in the distributed camp). There are pros and cons for either choice. There have been plenty of threads where such topics have been discussed.

    Typical injection points are:
    • 12V pixels - every 100 pixels
    • 5V Pixels - Every 50 pixels


    I personally inject my 5v pixels every 25 pixels and at both ends of the string. This is over engineered but it works for me.

    Hello, I'm Nick.

    I'm just barely getting into the hobby, after going down a rabbit hole that led to Canispater Christmas on YouTube, and now here.

    I'm 24 and from Bay City, MI. I have a background in electronics, and I am also an amateur radio operator (Ham).

    So far I am primarily interested in the bullet pixel string lights, so I have a number of questions regarding those and will post them on a new thread on an appropriate board.

    Thanks for having this great resource here!

    Welcome ! I recently got into bullet pixels made my first purchases this month and really like them over the others Iíve seen so far.
    Thereís a lot of info and great people here to help you . Enjoy

    Hi folks,
    My name Danny from Winslow, AZ. I work on rails as a freight conductor and was turned on to this since I saw a video of Johnsons family xmas lights a few years back. I figured it was time to pull the trigger and placed my first order of 1000 - 12V WS2811 / IP68 / Bullet Pixels /18 gauge BLACK wire / 4 inch spacing / 100 Count / XConnect Pigtails. I'm not sure what my first build will be, but I believe that this site is good place to start and to to get some ideas.
    The wife and I have always decorated the house during the holidays (especially Halloween), and would like to incorporate our older blow molds into a show that we could add on to each year. I'm hoping to create a few shows with 1 or 2 projectors, cut scenes with Charlie Brown, the original Grinch, Frosty and Rudolph(with of course, Heat Miser/Snow Miser), being synchronized with the lights(smart/dumb pixels).
    I see that I've got a lot more research to do with controllers as well as other components. I think I'm leaning towards using my laptop during my downtime away from home (about 8-10 hours a week for sequencing, research, planning). I’ve looked over the wiki, falcon looks interesting and hope it has enough room for expansion.
    Some other future ideas for builds would include house outline, arches, upgrade the spotlights, and possibly a 10' mega tree.
    Apologies for being all over the place on my first post. I just got finished with a 14+ hour shift, yuck!
    Thanks for the site, Happy New Year and cheers!
