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..
Raspberry Pi 5v Power Regulation
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..
xConnect: I was wrong, and I admit it…
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..
Re-Using 12v PSUs for 5v Pixels and LED Panels
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!)..
Add an OLED to a Raspberry Pi
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..
“Dolphin” Connectors for Pixel Repairs
I mentioned in an earlier post about Scotchloks ™ that I was also going to check out "Dolphin" connectors. I don't have any experience with them, but I have seen them used as an alternative to Scotchloks in Tele/Data-com applications. I bought a pack of them on Amazon. "Dolphin" Connectors These are "IDC" (Insulation Displacement..
Scotchloks ™ for Pixel Repairs
Quick Update (December 2021): Corning purchased 3M’s communications products division, so now these are sold as Corning Brand. I’ve been using these "UY2" connectors for emergency repairs this year (2021), and still have a few repaired strings left over from last year. I haven't had any issues with any of them. Older ones are showing..
UPDATE: I revised my thinking on this after realizing I was dead-wrong about xConnect connectors. See it here. This started out as a side-note for my Pixel Data Cables story. I decided it needed it's own write-up... I've seen a lot of hate for these online, usually from people who have spent a small fortune..
Pixel Data Cables
I've seen a lot of debate about this, and of course everyone does things differently. I just wanted to show what I am doing for my cables this year. So- you have a fancy new controller, like a Kulp K16A-B: Kulp K16A-B You stick it in a box with power supplies, terminal blocks, and maybe..
Doing pixels- I use these red ones the most.The white ones are excellent for smaller wires like data cables. These things are a godsend to anyone who tinkers with electronics or repairs low-voltage systems in cars, boats, etc. I can't imagine working with pixels without them. Sure- you can solder connections and shrink tube them,..
WAGO Lever Nuts
I use these things A LOT! They are great for temporary builds, as you can very easily disconnect and reconnect wires using them. They are also certified for permanent installation. Best of all- they will connect everything from 20AWG "alarm" or "network" cable up to 10AWG, mix and match, stranded and solid! They are good..
