Dev board and Dead servos

So after a little hiatus due to moving and marrying I'm getting back to getting this thing finished.

I put together a cardboard dev board so that I can move my set-up around a little easier.


For the astute, you may notice that 2 servos are missing.  Unfortunately, they were D.O.A and were completely unresponsive to any commands.  That's a whopping 13% of the servos I had ordered.  To be fair, at a price point of $3.50, I wasn't expecting much.  None the less, you'd think that a servo with a "QA" sticker on the bottom would have been QAed.

Upon opening the servo I found the following:



The capacitor at the top left should not be attached to that wire.  A bad soldering job is what is preventing this little guy from doing the only thing he knows how.  A little bit of heat from a soldering iron, and some insulating hot glue later, and Voila works like a charm.

Once these guys were working I spent some quality time with the Arduino library again.  Found a couple of bugs and squashed them.  I've moved the code over to a bitbucket repository for now and will open source it once I'm confident it's not embarrassing.
