I've received some inquiries from social media about why I pulled the fuses out of my K16A-B controller for our megatree and how it is wired. First, some background... This year we had planned on going from 2" spacing on the megatree strips to 1" spacing. Going from 75 pixels per strip to 150. We..
Projector Enclosure (2022)
I salvaged a projector that was damaged with a cracked case, and an exploded lamp assembly. It took a while and several bandaids to get all of the broken glass out of it, and then some super glue and a new lamp assembly and it is almost as good as new. Fortunately most of the..
Free-Standing Video Screen
In past years we have used a PVC frame with a frosted shower curtain on one of our windows for rear and front projection. This worked okay, but the PVC bent easily, so the frame wasn't quite square, and the adhesive hooks we used to hold it to the brick and soffit didn't hold very..
K16 Mega Tree Controller Rebuild
This year we were going to expand our Mega Tree to 150px x 32, but fell back to 75px x 32 for, reasons. In any case- I need to use all 16 pixel ports for the tree now, with two strands per port. In preparation for doubling the vertical resolution in the future, and to..
Building the Megatree Starburst, Part 1
Late last year I discussed a different Megatree topper with Kim and told her about this cool Starburst (or firework) effect you can build using these: Affiliate Link: She bought me THREE of them for Christmas, and wants one in this year's show. My plan is to build one with 2' PVC spines so we..
2021 Behind the Scenes Video
Here is a behind-the-scenes walk-thru of our 2021 show/layout. Obviously completely unscripted with me babbling semi-coherently. 😁 https://youtu.be/m_rzh7nM-fw I'm hoping to get time to post more details about the mega-tree and some of the other builds. It's just been a busy few months. Here is a pic of the K16 controller box that is under..
2022 Layout and Test
Update: We did have to scale this back. Hopefully we will be able to upgrade things more in 2023. While it's subject to change, I thought I would share our current layout plans for 2022... Highlights: Mega Tree moved to right side of the yard. Our real oak tree was blocking the view of it..
New xLights API, Package Script
Late last year, the xLights developers started adding API functionality to xLights so you can script repeating tasks. For example- you can roll your own batch-render or batch controller upload scripts now. The API is still being developed, but I asked the devs to include an option to package a sequence as part of it,..
Oak Hills Lights Power Consumption
Okay, the numbers are in... From Thanksgiving Day through New Year's Day we used a whopping 92.19 kWh of electricity. At $.12/kWh that's a total of $11.06! We did have a Raspberry Pi controller (Show Runner) and a small network switch running on separate (un-switched/monitored) power. Given the maximum wattage of the power supplies running..
A couple of FPP matrix display scripts…
Updated November, 2021: Script Updates and related text changes. Our show has a long matrix display above our carport/driveway that displays general show information, along with our "Tune To" FM frequency to listen to the music, and song information. Usually in order to do this- the information needs to be built into the musical and..
Wago Power Bus
This is one of those: "I'm going to see if this works..." builds. I needed some power buses for the top and bottom of our mega tree. The biggest down-side (and only, in my opinion) to using 5v pixels is you need a lot of power injection. We are using 75px. strands, so applying the..
More Power!
So the front of our house has a bunch of convenient outlets, but they are all run off the same 15A GFCI breaker. Knowing that likely wasn't going to be enough power for our show, we ran quite a bit of our 2020 show using extension cords from a set of 20A outlets we have..
ASAP Jr. Mega-Tree Pole Change
Just a quick post on this. For our Mega-Tree, I bought 1.5" and 1.25" galvanized conduit for the pole. We also have a hole in the ground for it already. I'll post more details about that build once we set the tree up this year. It quickly became obvious that these poles would be WAY..
