Enter the Space Tunnel

What’s better than 1 string of LED lights? 96. That’s how many. Each string of the 96 has 60 ws2812b LEDs, for a total of 5760 individually addressable RGB LEDs.  That’s not the cool part of [jaymeekae]’s Space Tunnel installation, the cool part is that they’re interactive.

Starting out with some PVC piping, dark cloth was used as a backdrop and the LED strips were attached to it. Several power supplies are used to supply the voltage necessary and each strip controlled by FadeCandy chips which connect to, in this case, a Windows PC via USB. Initially, computer power supplies were used, but they couldn’t supply the current necessary. [jaymeekae] used them for the first installation, but switched to better power supplies for further installations.

Once the lights were up and powered, [jaymeekae] started work on the interface to control them. Starting with a used bureau, [jaymeekae] cut out a section for the touchscreen, and installed the controlling computer in the bottom half. Processing is used to interface with the FadeCandy controllers and HTML is used for a user interface. Each mode runs a different Processing program for different effects, including audio visualization, a space tunnel mode (hence the name) and a cool drawing app where the user draws on the touchscreen and sees the results in the lights overhead.

Over several iterations, the Space Tunnel has evolved, with better power supplies and a better interface. It’s a great art installation and [jaymeekae] takes it to festivals, including one in Spain and one in the UK. There are some other LED string projects at Hack-a-Day, including this one with ping-pong balls, and this one that involves drinking a lot of beer first.

  1. Round the world and home again
    That’s the sailor’s way
    Faster faster, faster faster
    There’s no earthly way of knowing
    Which direction we are going
    There’s no knowing where we’re rowing
    Or which way the river’s flowing
    Is it raining, is it snowing
    Is a hurricane a-blowing
    Not a speck of light is showing
    So the danger must be growing
    Are the fires of Hell a-glowing
    Is the grisly reaper mowing
    Yes, the danger must be growing
    For the rowers keep on rowing
    And they’re certainly not showing
    Any signs that they are slowing
