Bricked Raspberry Pi Displays History

[eN0Rm’s] Raspberry Pis are much more than just another brick in the wall. He’s used the popular embedded Linux platform to build several small rear projection screens in a brick wall (Imgur link). Brick shaped metal enclosures were mortared into the wall of the building. Each rear projection screen is illuminated by a DLP projector which sits inside the metal enclosure. The Raspberry Pis sit on a shelf below all this.  The bricks are in a building in the Aker Brygge section of Oslo, Norway, and show historical facts and short videos about the local area.

[eN0Rm] could have used a PC for this task, the price for a low-end PC with a few graphics cards probably wouldn’t have been much more expensive than several Raspberry Pi’s with cases. However, this system has to just work, and a PC would represent a single point of failure. Even if one Raspberry Pi goes down, the others will continue running.

The current installation is rather messy, but it’s just a test setup.  [eN0Rm] has already been taken to task for the lack of cable management in his Reddit thread.  As [eNoRm] says – first get it working, then make it pretty.

    I did hear that there are a few showing up on ebay with b0rked HDMI ports but otherwise working.
    All it takes is one bad I2C DDC pin and kabloowie no output.

    I came up with a fix for this as mine has this annoying “feature” ; manually switch the TV to the Pi then it works when Pi repowered.
    Someone totally needs to make an IR “TV autoselect” shield for the Pi in order to get around this glaringly obvious problem with older (ie common) TVs and build it into the cable itself and powered from the I2C data lines charging up a capacitor to send the IR command set on each new powerup sort of like a reverse TV-B-Gone, would make a packet that way.
    Kickstarter anyone?
