RFBees and AVR Watchdog Timers...bark!

In my last post I mentioned using RFBees for a communications link between a remote sensor and a laptop PC. During my testing, the RFBees would become unresponsive at random intervals for some reason.

Wireless winter weather wonders - weather prediction with a swarm of *Bees

Here's a little project I've put together using a bunch of components from Seeed Studio:

UPDATE: Added a short video of hexed-bot moving around (on the leash) and sort of following the laser. UPDATE: Added new video of light tracking training. … Read more
This is really just a reworking of my Ardbot, where I've replaced the Arduino with the (awesome) Gadget Gangster Propellor Platform USB … Read more

For Halloween I Gave My Robot a Brain, or Fun With a Backpropagation Neural Network

I’ve long been fascinated by the concept of artificial intelligence and its application to robotics.

CNC machine smoke testing

My goal was to draw something in a CAD program, import it into Mach 3, and let the machine move through its paces to see if anything fell off, went up in smoke, caught fire, etc. I've attached a (crappy Blackberry) video of one of the first few times things worked as expected.

CNC - my summer obsession

Haven't posted anything for awhile - I've been busy building a CNC machine based on this book: Build Your Own CNC Machine (see http://buildyourcnc.com/Book.aspx for more details). The book very thoroughly describes the building techniques necessary to get up and running using the plans in the book and the suggested electronics.

Here are the basic materials I used (exact electronics specified in the book):

C328R camera and Arduino

Well I've decided to replace my 2.4 ghz wireless camera on Ardbot with this guy:

JPEG Color Camera - UART Interface

While it isn't as capable as the video camera I had planned to use, it has the advantage of having a serial interface that can communicate with the Arduino, uses 3.3v, so my hope is to be able to stream the JPEG images via XBEE to my PC.
