How long did it take you to do this?
From the time we were first inspired until the time we had the squares, rectangle and one dormer window matrix working and sequenced, it was two weeks, but most of that time was waiting on parts to arrive. We initially installed it inside our apartment for development, testing and sequencing the first song. Once we had the second dormer window matrix built, we put the lights in our apartment windows for further sequence development and experimentation. We added three more panels to the marquee, three more squares to its panel and a jacket (wireless). We then moved the display to the house site and later added the candy canes and snowflake.

What did you use for your parts?
For the initial setup:
- xLights – a free, open source program for running a light show
- Falcon 16 v3 – the controller that sends instructions to the house pixels - it is now out of production, and the Falcon 16 v4 has replaced it
- Simple chase controller – the Falcon 16 v4 was out of stock for the season, and the Falcon 16 v3 was on back order when we started, so we used this simple, non programmable controller to test the pixels
- ES Pixel Stick – the controller that sends instructions to the jacket pixels
- Bullet pixels (12 mm) – for the windows, posts and arches
- Flat pixel matrices (5 mm) – for the squares, marquee and jacket
- Flat strips (5 mm) – for the jacket
- Mesh for bullet pixels – to make the large window matrices
- Pixel pliers – to help insert bullet pixels into mesh
- 12 volt power supply – to power the windows, posts and arches
- 5 volt power supply – to power the squares and marquee
- Battery holder – to hold a M18 battery
- M18 Battery – to power the jacket
- DC-DC converter – to convert the 18v battery to 5v for the jacket
- FM transmitter – to broadcast the music
- Coroplast – used this for one of our posts (ran out of mesh) and were going to use it for the candy canes, but we’re going a different direction with the canes (will update when finished)
- Hoodie and yarn
- Wire, heat shrink, connectors, fuse holders, fuses, switches, power strips, etc.
The candy canes and snowflake were a late addition, and for those, we made the pixel meshes ourselves. To do that, there are a few more needed items unless you want to cut everything by hand:
- Cricut - to cut the HDPE - the Maker 3 is the newest one, but the Maker does almost everything the Maker 3 does, and it was on massive sale
- Knife blade - the Cricut does not come with this tool by default
- Large mat - the Cricut does not come with the large mats by default - though you can still make smaller props with the smaller mat it does come with
- HDPE plastic - the material to make the mesh out of

How did you video this?
Our cell phone is a $40 special, so it does not have the best camera. When first trying to record using the default video camera app, everything was massively overexposed because you cannot change any useful settings. We installed
HedgeCam2, and that allowed us to drop the ISO to 100 which helped a lot - still not great, but at least you can tell what's going on. We probably could have dropped the brightness of the show a little more and recorded it again, but it was late, cold and icy. Next year maybe we'll get a better camera. Baby steps.

What did you use to edit your videos?
We picked up
NeoFilm Express when they were having a short 100% off sale (i.e., free). It's much more powerful a video editor than we really want, but the price was right.

How much does it all cost?
The initial set up (before candy canes and snowflake) that we have for Christmas 2021 was approximately $1600, but you can spend far less and far, far more depending on how fancy you want to get.
At an absolute minimum, you need a controller (even just the simple chase controller mentioned above), some pixels (bullet and/or flat), a power supply (appropriate voltage for the type of pixels you are using) and some wire, but to really have fun with making your own sequences, you will want a controller that can interface with the xLights software. There are a bunch of different ones available depending on how many pixels you want to control, what your future plans are, and how much you want to spend.

How can I get started on my own pixel display?

Do I have to have special skills to create a pixel display?
Full disclosure: we are an electrical engineer and a software engineer (both retired), but that does not mean you need advanced skills/knowledge. You have to be able to read simple schematics and do basic wiring – even with a ready-to-run controller because you will probably have to inject power into your strands. If you don’t know how to splice wires together (solder and heat-shrink) or what the difference between a 12 volt and 5 volt power supply is, or what polarity means, then this is probably not the project for you – you can destroy your controller and/or your pixels if you hook up things together incorrectly.
Other than the electronics, you will need basic crafting skills (and patience to pop all the bullet pixels into the mesh) as well as basic computer skills to create your sequences.

Do you have any tips quick tips or warnings?

Test all your pixel strands before popping them into a matrix. In the 1500 bullet pixels we bought, there were two bad pixels – one of them worked fine when turned on, but when turned off, it stayed faintly blue; the other bad one just didn’t turn on at all. We built the first window matrix before noticing the blue one. It’s not a big deal to cut out a bad pixel and replace it with a spare, but it’s much harder to do that once they are all popped into the matrix (very bulky and heavy). Fortunately, we caught the other bad one before making the second window matrix.
Be aware that the pixel strands might not be consistent – even within a single manufacturer and even within a single product. We ordered one set (500) of bullet pixels and – only a week later – reordered two more of the exact same sets. Unfortunately, it turned out that the first set used completely different circuit boards for the pixels than the later two. The first set draws about 50% more power (and consequently, the pixels are about 50% brighter). That wouldn’t be a problem except the first set was for one window, and one of the second sets was for the other window. In their raw state, you can actually tell that they are different intensities since they are close to each other, and we had to scale down the brightness of the first set to match the second. It’s not a big deal, but had we known that was going to happen, we would have used the first set for the posts/arches and the both seconds sets for the windows (so they’d match intensities).

Don’t trust the wire colors on the bullet pixels – always double check the wiring with a multimeter especially when splicing in pixels from a different strand. Test using a cheap chasing controller instead of your main controller in case the wiring of the pixel strands is really messed up.
Get the pixels that have the xConnect connectors already attached (the same for getting connection wires). They were all sold out by the time we started this project, so we didn’t have a choice, but those things are not much more expensive and will save you many hours of work.

Make sure you wash any clothing you decide to embellish. The Walmart hoodie that we got sheds dye and has turned the trim (and anything else it touches) pink.

Will you have more songs?
Yes eventually, but that's unlikely for 2021 (maybe something new for New Year's Eve).)
-
Will your website always be so black-and-white drab?
Probably. We'll add some more features and try to keep the parts list up-to-date, but I hate CSS, so making it prettier is the lowest priority item on the list.
-
What are your plans for next year’s display?
You’ll have to come back next year to find out!

I have a question that you haven't answered.
Feel to
send it, and we'll try to answer it if we can or refer you to somewhere that might.
