Happy to see our screen here on hacker news! figured I'd post the behind the scenes video here too since it could be of interest to someone on this site. https

Great video - hope to see a longer one / blog post if F21 lets you publish details. Is there a story behind the PCB that's shown on fire, or was that just for show? ;)

  We anticipated some static from all the ribbons, so the superstructure is heavily grounded and made of aluminum, we also have aluminum plates inside each pixel module. But when our step-drivers started catching fire we bought a 3M 718 static sensor, it maxed out at 20kV so I actually don't know how much static we had on the ribbons. We ran tonnes of more grounding wires through the modules and that took care of the problem. But yeah, static caused a few fires here before we figured it out.

    Static electricity was a big problem on early drum computers.

    Take a look at anti-static tinsel, it's perfect for this type of issue: http://www.statictinsel.com/how-to-use-tinsel.html http://www.statictinsel.com/how-to-use-tinsel.html

I had a hunch this was a BREAKFAST piece before I even clicked the video. Really impressive project. Love what you guys have been doing!

Beautiful piece. I was also a big fan of the dot display you guys did previously... https://www.youtube.com/watch?v=x3jkoIyJgoc https://www.youtube.com/watch?v=x3jkoIyJgoc Seriously, if you ever thought about mass-producing the dot module (or even a split-flap character display), I'd buy them by the hundreds.

Would you have any interest in demoing this at the "other" breakfast in NYC - NYC TechBreakfast? Check it out at http://meetup.com/nyc-techbreakfast http://meetup.com/nyc-techbreakfast and drop me a line if so.
