I have been super busy with other things, but I did get something new going. Since my turret is still needing some final details, I had some more parts for a 2nd test platform made.
Here is a pic. I got another standard Futaba servo, and a HC-SR04 ultrasonic sensor to start with. I found the best deal on ebay of course and got fast shipping. I have been doing some testing, and this sensor is pretty easy to use with the Arduino. Here is the link if you are interested in a similar part:
