Lunar Den Lights is a technical blog primarily covering RGB "Pixel"-based holiday light shows. It provides a backstage view of our current light show: Oak Hills Lights. You will also find some 3D printing information, as we use some 3D printed components in our light show, and that is one of my other hobbies. This..
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..
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 for many, and it was just in an awkward place for its size. We are also more-than doubling the..
Since this Web site isn't working very well for posting my Arduino code and PHP scripts for FPP and xLights, I'm moving all of them to GitHub. There is a new GitHub link in the main menu. I've also pinned the official FPP and xLights projects there as-well. I'm going to move everything over there..
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,..
It's time to start ordering pixels for this year's show! I order all of our pixel strings starting now through about April. I add at least 1000 to what I feel we will need this year, and then split it up over a few months worth of orders. This gives us all the pixels we..
We had a lot more bad pixels than last year. A lot of shows reported significant bad pixels this year due to production problems in China over the past two years (due to COVID-19). I believe ours are a combination of that, and just the bad weather we have had this season including extreme rain..
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..
I've posted before about how awesome "Solder Seal" connectors are. One of my heroes when it comes to builds and electronics is former Mythbuster Adam Savage. Well, he just released a new video about them that I wanted to share. He does a better job of showing how to work with these things than anything..
I really love how this turned out... https://www.youtube.com/embed/udn0EwN0NiM ...so, I'm going to share it. I want to thank the xLights Singing Faces project for the lyric tracks. Everything else was just me having fun with mostly whole-display effects. I'm giving this away. As-is, no-warranty, no-support. There are lots of resources for importing sequences online, and..
Wow, between storms, deer, bad pixels, and software glitches- it's been a "fun" week... The big storm that blew through earlier this week took out some of our sparkleballs, and we had controllers and electrical cables literally floating in a few spots. Fortunately we were able to get everything dried out and working again fairly..
We've been hard at work getting things set up for our show this year. Too busy to do many build updates right now, but they will be coming. As of now we've got almost everything set up except for the new virtual matrix/video projection screen, front roof outlines, and SparkleBalls. We have all the parts,..
I love these Wizard of Wire differential receivers. They connect directly to a Mean Well PSU, and the angled design means they still fit in a standard Harbor Freight or similar plastic ammo box. https://www.wizardofwire.com/product/meanwell-90-degree-differential-receiver-with-power-injection/ There is one problem though... The pixel ports and power injection ports are fused at (and are rated for a..
