Barco make huge modular LED displays. They range from the small (shown on the left above). To full stadium sized installations.<\/p>\n

\"barco_block\"<\/a><\/p>\n

The system seems to be broken down into a series of control boxes. Each box manages a handful of LED arrays. A typical control box seems to manage about 9 individual arrays.<\/p>\n

I found a few of these arrays in a junk shop going for about 2USD. So I decided to pick them up and play with them. They appear to be part of the IP65 rated, or at least outdoor line of LED displays from Barco.<\/p>\n

\"barco_front\"<\/a><\/p>\n

They’re 8×11 arrays of RGB LEDs. You can see the LEDs are quite well sealed in. On the back is a 23pin connector embedded in a massive heatsink. There’s also a fan under the gray plastic.<\/p>\n

\"barco_back\"<\/a><\/p>\n

In order to withstand harsh outdoor conditions these units are heavily sealed. It too some serious work getting inside:<\/p>\n

\"barco_hack\"<\/a><\/p>\n

The LEDs are sealed below a plastic overlay and a black mesh which you can see hacked to bits in the above picture.<\/p>\n

\"barco_leds\"<\/a><\/p>\n

They look like standard diffused RGB5050 LEDs. Removing this PCB was serious work, the whole enclosure has been flooded with some kind of resin. I assume this helps make them weather proof, but also be rated to help conduct heat to the heatsink. I suppose when you have a massive array of these things, moving the heat must be a challenge.<\/p>\n

\"barco_not_pcb\"<\/a><\/p>\n

Though you can see traces, components, and even silk screen markings. The above image is \/NOT\/ the PCB. It was what was left behind after pulling the PCB off. A bunch of stuff remained embedded in the resin!<\/p>\n

Here’s the actual PCB:
\n\"barco_pcb\"<\/a><\/p>\n

That resin really made a mess of everything, pulling the ICs right off the board. One, fell out while I was prying it apart:<\/p>\n

\"barco_ic\"<\/a><\/p>\n

Interestingly the ICs here are either remarked, or they really are custom Barco ICs. I guess that’s not impossible, but I find it slightly surprising!<\/p>\n","protected":false},"excerpt":{"rendered":"
