6 years ago Curious how you wired that. There are only 3 ports on the regular buffer card.
Also those tiles suck a ton of power, so I knew that a UPS would never hold that thing for 156 minutes. The Chinese make LED displays similar to this, and the slightly bigger versions of those displays need 2 AC circuits by themselves. just FYI.

6 years ago I used 2 parallel chains. I don't have a better picture of the back than this, for some reason.
The Wattage draw when on and running is ~34w
The UPS that I was using was old and catastrophically failed at around 20mins, no matter what load I put on it.

Its probably the battery in the UPS, Time to changer her out and itll be good as new!

Camera did a horrible job picking up the images because of the refresh, but youll get the idea.
It's a Team Name Caption panel I designed that goes into a scoreboard.

5 years ago Would you be interested in sharing your code? I am especially interested in the web interface you used to control it. Maybe some pointers anyway. Tx JT
I finally got my scoreboard to the point that it would work at the field for a game. I took it to our last home game of the year but only had an old UPS which said it would power it for 156 minutes but lasted 20 minutes - bit of a disappointment.
We had an away game in Baton Rouge last Saturday which is 4.5 hours drive away. I worked late on Thursday night, tweaking the software, and then late Friday night, tweaking the frame. We sourced a generator for the field and to ensure good quality power I passed it through the UPS.
End result was a fully functional scoreboard that could be seen at least 60ft away in the very hot, very humid, very bright Louisiana day.
The refresh rate was around 120-140Hz, which meant that none of our smart phones could get a good picture.
But this picture was taken by somebody with a digital SLR who lowered the shutter speed. It is at the end of the 1st Quarter, we ended up winning handily by the end of all 4 quarters.
