Central PA Open Source Conference 2010 (CPOSC), which will be held on Saturday, October 16, 2010 at Harrisburg University. Tickets include include access to all three tracks including 21 awesome speakers, breakfast, lunch, an afternoon snack break.

The number of tickets available is limited based on the size of our venue, and last year tickets were sold out before the conference. Don’t miss your chance to register!

So, head on over to www.cposc.org to register, and we’ll see you in October! :)

The kits I ordered from Adafruit arrived! Here’s the list:

• 2 x XBee Adapter Kit [v1.1]
• 2 x XBee Module – XB24-ACI-001
• USB TTL-232 cable – TTL-232R 3.3V
• Adafruit Motor/Stepper/Servo Shield for Arduino kit – v1.0

The XBee module that Adafruit sells is the chip antenna version. According to Parallax, “The wire antenna versions will provide 20-30% more distance than the chip antenna in the same environment.” Still, I should be able to get at least 300 feet out of it.

Playing with the Arduino a bit again tonight. Here’s a snippet (source) to read the analog output from a Sharp GP2D12 analog distance sensor and convert it to centimeters:

Seems to work reasonably well.
