First Test of RC Controlled Mini Sumobot
We decided that it would be fun to have an RC controlled mini sumo bot competition. Instead of having brains on board, we're controlling these bots with RC transmitters.
Here is a first test run of a RC controlled mini sumo bot.

Snatched off the PARTS forum - Big Pololu Black Friday Sale
My name is Ben and I'm an engineer at Pololu (www.pololu.com). I'm writing to
let you guys know about our upcoming Black Friday Sale (starting Thursday, Nov.
24th at midnight (PST) and running through the end of the day on Monday, Nov.
28th). This is our biggest Black Friday sale yet, with some pretty substantial
discounts (most over 40%) on many of our most popular products, and this year
we're also cutting up to $25 off your entire order, so savings aren't restricted
to just sale items. You can find out more about the sale here:
http://www.pololu.com/blackfriday2011
This year, we'll be offering our 3pi robot (with our USB AVR programmer
included) for $49.95 to the first 50 customers ($62 off the retail price). This
is a great opportunity for members of your group to stock up on parts for your
next robots! I hope you all have a happy Thanksgiving!
- Ben

USB to TTL Converter
This is ready to use in a project needing USB to ttl. It has the USB converter chip built in, the USB connector built in, and it will solder into a standard db9 circuit board footprint.
There are also USB to rs232 varieties and the TTL versions have 5v. And 3.3v varieties. It's currently $15.50 at digikey. I think it would replace the Modern Device BUB for the most part and goes right into the project.

Sensor Board
Here is an interesting sensor board sold as an obstacle avoidance sensor... limited to 50cm distance. This would make excellent forward looking eyes on a sumo robot.
