I'm a mechanical engineer. I tend to ask a lot of stupid questions to try to figure out what all these electronics and computer guys are talking about.

I used to be the senior engineer at Ernie Ball/Music Man Guitars in San Luis Obispo, CA, where I learned a lot about building electric guitars and basses, 3-D CAD (AutoCAD, Mechanical Desktop, Pro/E), CNC programming (Fadal, Thermwood, MasterCAM), and building trucks that transform into concert stages.

After that, I was a teacher. I taught woodshop, drafting, and computer animation. Sounds pretty cool, right? Wrong. I hated it.

Now I work for Smith Sport Optics. I do all of their 3-D CAD work, reverse engineering hand-made models for goggles, helmets, and sunglasses in Rhino so that they can be produced by plastic injection molding.

I also make music, either in an electronic format using old analog gear or by playing bass in a band. I like to collect and play vinyl records. I've done a lot of live sound engineering for bands, and some studio recording. I know a little bit about climbing big walls in Yosemite. And I have a cat. I don't like dogs very much. Or children.

So far, I've made a MIDI-controlled, hi-intensity LED light set for Portland band FLESHTONE, and am working on a CAD controller to make my day job easier.

  Hello Mr. Hans Lindauer.
  Mr. Lindauer my name is Rumenigg Nogueira Vieira and I'm from Brazil.
  I'm trying to build a LED WALL like yours on this post http://dorkbotpdx.org/blog/armatronix/led_video_wall to show ads, pictures, videos, for digital facades and showcases, but I don't know how to start.
  I bought some equipment, 30m of LED Strips 5050SMD 52LEDs/m LPD8806 and 2 teensy 3.1 but I don't know how many ports I must use to control that pixels and the library to control the matrix. My matrix is 52x30.
  I didn't found these informations at forum and the some informations are confuse.
  Could you help me? Do you have some DIY tutorial to sell me?
  Thank you.
