Some of the people.	The free table.	Brian Schmalz made a frosting squirter.	Another view.
His control program.	A couple of cookies and some sample frosting patterns.	Closeup of frosting.	The squirter is driven by Brian's microstepper driver modules and his Bit Whacker. He designed them all.
Carrie and Jr. Dickson.	Jean-marie Bertoncelli is running his Lego line follower.	Following lines.	0712_19.jpg
Bruce Shapiro brought his rope spitter.	Rope being spit across the room.	Look how well that rope stands straight up.	Jamia had these Lillypad LEDs from Sparkfun.
Another view.	Somebody had this 'One laptop for every child' laptop. I think it was William McTeer.	Notice that is has a built in camera.	Lewis Dickson had his Parallax Propellor stuff. Notice that ominous big red button.
He has it set up to drive 4 R/C servos.	Lewis also had this robot base. It used to have a Propellor chip, and maybe it still does.	This photo is a photo of Pete Bergstrom's new robot.	Terry Schumacher's power control module that he is working on.
This is Jeff Sampson's Netburner board. It has a Coldfire 5270 processor. It also has a gyroscope, accelerometers, a barometric pressure sensor and a Wii Nunchuck.	This is a plot of Jeff's Research 3 robot when it was diving around (manually) in the Cray offices. The red and brown dots are sonar echos. The blue line is where the robot thought it was.
