DS1307 RTC Breakout Board Rev 1

DS1307 breakout, board only

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.


First prototype of my 6v6 amp is done!

I finally have my 6sn7/6v6 based prototype done! I chased down a couple of noise sources and now it plays sweet, sweet music. Now I just have to put in a more permanent container and add a couple more features.
