[derektroywest] has posted a detailed step by step breakdown of making a Daft Punk costume. They’ve done a great job, the overall look is very convincing. They include links to where to get each part as well as information on how they pulled it off. The helmets were inspired by the timelapse Daft Punk helmet build. As you can see in the video, they don’t have the entire visor made into a display, but the effect is quite nice, especially because it is multi color.
[Alex] put together this lovely minimal LED project. The square pixel matrix is soldered directly to the microcontroller in the same style as EMSL’s Micro-Readerboard. During the prototyping phase he used resistors to limit the current from the programming board. The final product doesn’t use resistors and manages the current draw by only turning on a single pixel line at a time. The illustrated assembly guide is very thorough and should help your create an equally compact device. Check out a video of it in motion below.
