Google Tech Talk

I’ve been busy talking about how I use the Propeller in all my projects- including DanceBot, ViewPort, 12Blocks, PropScope, and TBot. In the last 2 weeks I’ve given 6 presentations with lots of demos- including a tech talk at Google. It’s always quite an experience visiting the Google campus- highlight was walking up the stairs and looking up to see SpaceShipOne hanging above me.

A dozen presentations about my projects…

I’m headed around the world to give a dozen presentations about my projects to various clubs, companies and schools.  Here’s a link to photos and videos from my first talk- given to the Robotic Society of Southern  California- just an hour after flying in from New Zealand!

Book published!

A while ago Parallax asked me to contribute to an official guide for the Propeller- today it’s finished!  It’s available at Amazon.
Here’s more info:
Parallax brought together 9 experienced authors to write 12 chapters on the many facets of multicore programming with the Propeller chip.
The book begins with an introduction to the Propeller chip’s architecture and Spin programming language, debugging techniques, and sensor interfacing. Then, the remainder of the book introduces eight diverse and powerful applications, ending with a speech synthesis demonstration written by the Propeller chip’s inventor, Chip Gracey.
Numerous illustrations and example programs accompany each application. Example source code and other related resources are available for free download from!
