[chbot] AVR Butterfly progression?

[Hanno Sander]

I'm still quite happy with the Parallax Propeller.
It's a chip with 8 independent 32 bit processors running at 80 MHz
driving 32 general IO pins.
Community has built objects for pretty much anything and support for
over 100 languages.

Plenty of processing power to capture color video, bitbang USB, and
output video.  Having 8 independent cogs makes it easy to reuse
existing components and build more complex projects one step at a
time.
Only $7.99US for a 40 pin DIP or $25US for evaluation boards like the
QuickStart.

In the past 5 years I've used the Propeller in my vision-guided
balancing robot, a USB oscilloscope/logic analyzer/frequency
generator/spectrum analyzer, a development tool for engineers, an
educational programming language, and an educational robot.

I'll bring some demos for Monday night :)
