1.27mm Headers in Eagle

Hi, I'm trying to make a breakout for a Wandboard. And I need to find an Eagle library that has 1.27mm pitch male headers. These are half the pitch of your typical 0.1" headers. 

Does anyone know of a good library that has these headers?


Getting Started with 3D Printing

LMR is a great place to work together, learn and build. When you put cool new tools and tech in the hands of the community here, we can make awesome new things! When I first started wanting to build a 3D printer in 2009, there honestly wasn't much documentation out there to learn from  like today, and lots of my questions were left to the Great Google. Here is an attempt to at least collect some info for those starting on the 3D printing path...

Designing the new body for my robot...

The first robot that I have ever made currently has a cardboard body. As one can imagine, cardboard has its limits, both in durability and aestetics..  So the last few weeks I decided to look around for another material... I wanted something that is relatively easy to form and work with and not needing a whole set of new, special, tools... I came across plexiglass as an alternative and my choice was quickly made.

This is a simple Arduino Light seeker. It has an Arduino Duemilinove on board. It is powered by 2 AA batteries for logic( with boost converter), and 4 AA batteries … Read more

Sketch to CAD?

I have a paper & pencil sketch of my robotic design and I was wondering if there is anyway to easily create a CAD model by scanning my sketch into the computer. I user Google SketchUp and Alibre Xpress (yeah I'm cheap) and I can't afford anything "more advanced".  If there's anyway to do this, I would love to know, or if you could point me to a tutorial, that would be greatly appreciated.
