Converting a Unipolar stepper to a bipolar
So why would you do this, well unipolar (5-8 wires) allow for more fine control, but have less torque to turn things. Most 3D printers and CNC’s use bipolar too. So…the convertion is pretty easy and you can get the motors … Continue reading
Xerox sues city of Rowlett
It sounds like Xerox had a complicated contract with the city and the city was loosing money on the deal too. http://starlocalmedia.com/rowlettlakeshoretimes/xerox-files-lawsuit-against-rowlett/article_8ea2a55e-18c7-11e4-82da-001a4bcf887a.html

Build a Pantograph with a Dremel
Nice write-up to build a Pantograph (thing that draws, in this case cuts, a duplicate of what you are tracing). Only thing I might do differently is a better holder for the dremel. Maybe something that can thread in. http://starlocalmedia.com/rowlettlakeshoretimes/xerox-files-lawsuit-against-rowlett/article_8ea2a55e-18c7-11e4-82da-001a4bcf887a.html
An $8 AVR programmer
Nice build for programming AVR chips (arduinos) for bare board or chip systems. Only $8 (more like $10 in my case) in parts. http://www.instructables.com/id/How-to-make-your-own-AVR-programming-station-for-u/
