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..
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..
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..
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..
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..
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..
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..
We have a lot of Raspberry Pis that run various elements of our shows, and powering them from "wall warts" in enclosures isn't always practical, especially since we are already running 5v power everywhere. The problem is- if you power them using the GPIO header, there is absolutely no internal voltage regulation. So- a voltage..
Last year, I wrote a post about how there is no reason to use "proprietary" connectors like xConnect over the JST connectors that most bulk pixels already come with. I still believe JST connectors with a dab of dielectric grease are perfectly fine for joining strings of pixels together in props, or mid-strip on a..
Last year there was a lot of debate among Pixel junkies about 12v pixels, in part due to a bad production run from a popular Chinese supplier that resulted in fires. I did my own (controversial) analysis and decided that I would eliminate the 12v pixels we already had in our show (on our roof!)..
It's kind of silly since they spend most of their time closed up in a weathertight box, but I really like the little OLED screens on the Kulp controllers. They give me a quick indication if the controller is working, so I can at least rule it out (for the most part) if there is..
Yes, I changed the name (and the look)... This site was initially started as joke, called BubbaLectric.com. It was supposed to represent a series of my cost-cutting (cheap!) and unsophisticated hobby builds, using satirical "BubbaTronic" branding. Since I first set it up- I've grown the site with a lot more practical information about my builds..
Just a quick tip here. You can often find these on sale at Harbor Freight for a few bucks: Cheap Junk Harbor Freight Wire Stripper They are utter garbage when it actually comes to stripping wire. BUT- they are excellent for getting the last few clicks out of a zip tie! Excellent Zip Tie Tightener!..
