Blinkenlights are really big in hacker culture, the hackcenter where our table is located is completely full of led strips, installations, projectors and a ton of other things that glow, flash or blink.
ATTENTION This room is fullfilled mit special electronische equippment. Fingergrabbing and pressing the cnoeppkes from the computers is allowed for die experts only! So all the “lefthanders” stay away and do not disturben the brainstorming von here working intelligencies. Otherwise you will be out thrown and kicked anderswhere! Also: please keep still and only watchen astaunished the blinkenlights.
The obvious think to do with blinkenlights is to get them onto the network, my udp panel continues this glorious tradition. There are loads of awesome blinkenligths on the network:
The Milliways sign is made from addressable led strips mounted on a frame. There is an awesome ethernet connected controller board that drives all of the leds.
There is a group of hackers sat in front of the flipdot sign day and night playing with it. The flipdots are small electromechanical modules that can be either white or black, the modules take a fraction of a second to swith and make an awesome sound as they do.
The flipdot sign is controllable from a (probably tempory) website.
