After seeing the interest people put into the automated A-Spec grinding, I thought I'd share my B-Spec grinding method done with the Arduino Uno (as a matter of fact, this works for A-Spec as well).
NOTE: This will only work for the Arduino Uno (tested) and possibly the Arduino Mega 2560. The Uno and (if I recall correctly, the Mega 2560) differ(s) from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. This allows the board to be seen as a HID by flashing the Atmega8U2 with a custom hex file.
What you'll need:
Hardware:
Arduino Uno (or Mega 2560) x1
Usb cable x1
Wire about an inch long and stripped on both ends x2
Software:
Arduino IDE
AND
Flip Programmer (windows only)
OR
MacPorts & dfu-programmer ("sudo port install dfu-programmer") (mac only)
OR
dfu-programmer (grab it from your distro's repos) (linux only)
AND
My big-bag-o-fun
PS3:
Copy of GT5
Red Bull x2010 (any version)
Start off by uploading this sketch to your Arduino:
Now, you'll need to throw your UNO into DFU mode. To do this, (while your Arduino is plugged into USB) use one of the short wires to bridge two points on the back of the board near the map of Italy (just below). With that in place (hold it down with tape if you'd like) use the other wire to bridge the the two points seen here:
If done correctly, your UNO should now be in DFU mode. (Confirm this by checking the list of serial ports. The serial port for your board should no longer show up.)
Now, flash the 8u2!
Windows: Open flip, load the hex, select at90usb82 and flash away.
OS X/Linux:
Now unplug the board and plug it back in. Careful though! It'll start typing exactly 6 seconds after the board receives power. Open notepad/gedit/emacs or something.
Go hook it up to the ps3! Fire up B-Spec and go to either Extreme Series > Dream car championship > circuit de la sarthe (best for farming XP) or Extreme Series > American Championship > Laguna Seca (best for farming money).
The UNO will alternate between sending the "return" key and the "down" key, so you can simply walk away and come back whenever you want to collect your winnings.
Enjoy.

Note (Vista/7 64-bit Users Only): Windows nags about unsigned drivers, and that's what Atmel provides with their Flip programmer.
To circumvent this:
Right click "Computer" and select manage. Select device manager. While the UNO is in DFU mode, right click "UNO DFU" and select update driver. Select "Location on my hard drive" (not exactly sure of all the specific names as I do not use windows). Now download this and extract it somewhere. Type the path to the files into the path box for the driver. Follow the rest of the steps normally and all should be well.
