Self Balancing Robots 101
Glenn's presentation will cover the basics of self balancing robots:
Glenn Phillips got into the computer business around the era of the Mac Plus. Glenn's last job was the owner of Gorge Networks Inc. a rural Internet provider using fixed wireless and dsl. The business was sold in 2010 and Glenn has been on the Obama plan ever since.
Glenn became interested in the Arduino a couple years ago, but he had no programming experience. At some point in the process Glenn began to control servos and motors from his old RC collection. Computer control of motors was fun, interesting and possibly a job in the future.
Self balancing robots seemed to be the holy grail of motor control! Constant feedback from sensors is processed and translated to power and direction of the motor. Any issue with any component of the system is immediately apparent.
Glenn is also a cheap Yankee so his creations use salvaged parts from electric bikes, scooters, wheelchairs, laser printers and computers.

An open-mic session for those looking to show off a project, ask a question, solicit help, or incite collaboration.
The Bus Pirate came up as a topic on the mailing list a few days ago, and I realized I hadn't yet shared the slides from my presentation (a year ago now!) on how to use the Bus Pirate to poke and prod I2C devices like sensors and EEPROMs. So for those of you not on the mailing list, here you go:
Last night I released OctoWS2811 ... after spending pretty much all Sunday making this 3 minute video:
Everyone at the meetup a couple weeks ago saw this right when it was first showing video. Since then, pretty much all the work has been on the documentation and minor code improvements.
Ward Cunningham, Russell Senior and David Turnbull bring their respective expertice to this 21st Centurary Amateur Radio Project. Federated Wiki on Raspberry Pi provides content management that would be useful for health and welfare radio traffic after a disaster, or, for live-blogging the MicroHAMS Digital Conference next month.
I was lucky enough to receive a Leap Motion Controller. It acts like a short-range Kinect for your hands, tracking the position of each individual finger. The Leap's sensors are fast, and spookily accurate. I love it.
This is J.R. Stoner's blog post.
This is a picture of my muse, Mr. Humphrey Lyttleton Katz or Chairman Humph, for short.
He is saying here, "Go away. You're so boring. Get over yourself."
Actually Humph is probably the neediest cat I ever had, in his own weird way.
Enough about Humph. Here is a listing of some of the projects I have been working on, of late:
This one is called the Powah. It is just a little on/off toggle with an indicator LED. It is designed to mount on one end of my breadboard, so as to reduce the wear and tear caused by excessive insertions of power bus leads. The board is approx 1 cm^2.
Ok - so I'm new to this - The Raspberry Pi got a lot more press than the Arduino and I jumped on board the Raspberyy Pi train without knowing the options.
My goal was to build a doorbell to solve the problem of not hearing it in all parts of the house (3 stories).
I followed this blog http://www.blog.solidstatediskshop.com/2012/raspberry-pi-doorbell-python/
For the last several days I've been working to compile the latest free GNU Toolchain for ARM published by CodeSourcery (now owned by Mentor Graphics).
This process has not been easy. In this lengthy blog post, I'll share all the patches I've written, with detailed explanations of exactly what errors I encountered, what I've learned about each problem, and how to work around it.
Edit: full source is on github.

We will be taking advantage of the audio/visual system to have an open-mic style event. Think: OpenDork meets OpenMic. Bring your own signal!
I wanted a board that shows the state of all I/O pins on LEDs with all of these properties....
