So a few weeks ago, I posted a video of a series of small LED signs I had ordered from eBay. After many weeks of trying to figure out what to do with them, I decided it might be cool to build a multi-line information display for my building.

First, I took all of the plastic cases apart, freeing the internal sign electronics.

Next, I mounted the signs one below the next onto a piece of Lexan. I made my own standoffs, which is why they are so uneven and poorly aligned.


Here's a closeup of the power circuit I built. The signs use between 500 and 1000 milliamps at 9v, so I built a circuit with three 9V 2A regulators powered by two 12V 2.5A switching supplies.


Here are the signs mounted onto the lexan.


Here they are powered up:


And finally, with the smoked plexiglass case applied overtop. You can actually read them now! The top sign is green, as you can see, and the remaining 6 signs are red.


Anyway, this project still needs the addition of an Ethernet to Serial bridge, mounting points, and the case needs to be finished and closed.
