Missing Links.

One of the joys of the Arduino Cult Induction Sessions is that mistakes and omissions are generally caught on the spot and there is no lag between the steps we forgot to include an the instructions and the person who's board isn't working.

Dorkboard assembly tutorial is online

I've placed a brief Dorkboard assembly tutorial online. It's my first attempt at a photo documented circuit tutorial, so feedback is always welcome.

I'm sure there are nuances/subtleties that I've missed...please report them and make the page better!

DS1307 RTC Breakout Board Rev 1

[1]

As part of my clock project (yet to be documented) I needed an accurate real time clock (RTC). I selected the Maxim(Dallas) DS1307. I based the decision mostly on it's popularity and because of the availability of C libraries for the AVR. Sparkfun has breakout board that's similar to this but i didn't feel like paying $20 plus shipping for such a simple board (plus I think that Don's parsimony is rubbing off on me a little). In addition I wanted integrated pull-up resistors in the i2c lines.
