DIY Kraftwerk-inspired LED tie
Evil Mad Science Laboratories has step-by-step instructions (and video) for a DIY Kraftwerk-inspired LED necktie.
The good news is that it’s actually easy to make one. And the starting point? A circuit with nine red LEDs and just the right spacing: our open-source Larson Scanner kit. With minor modifications—a software change and dumping the heavy 2xAA battery pack—it makes a pretty awesome tie. In what follows, we’ll show you how to build your own, complete with video.
