Nice little video showing off what he can now do with his dome panels. Subscribe for more updates ;)

Have just realised I only control sets of servos in this video, either via scripts or all top, or all bottom. I also have control over each individual panel too :)
So here's a few pics!
I'm using an Arduino Uno and an Adafruit to control these with
[URL="https://drive.google.com/folderview?id=0B5B8A65frsBgZDJaSlFYSW1CR0U&usp=sharing"]the BHD code[/URL].
The servos are cheap ones from ebay - Tower Pro SG90 :)
The servos are being powered through the slip ring. The Adafruit has 2 power supplies that need to be used. One for the controller, and one to power the servos themselves. I'm powering the controller from the Uno +5v and ground pins, and the servos (via the Adafruits screw terminals) from the main battery, through the slip ring, into a pololu 5v converter. Lots of wires :D
Arduino Uno on the right (which I'm sure you're all familiar with by now), controls the 3 HP LED's, and the dome servos.
On the left we have the Adafruit. This is controlled by the UNO via I2C. The first 3 servo spots on the Adafruit are for the HP's which I don;t have controlled yet (only one movable resin one at the moment). I'm using the BHD code, so instead of altering it all around, I just set it up like this.
Like an idiot, I managed to drill the holes the the lower door hinges over size, so I had to alter the clevises to take an M3 bolt. Don't do this :) It's a headache. In this picture you can still see the pen mark where I aligned the hinges where I wanted them.
The large rear door is quite heavy, even in styrene! I found it was best to use a point closer to the servo itself to attach the servo rod to. In hindsight, I should have done the same for all of the hinges. Larger range of travel on the servo, plus more power!
I'll update the blog properly as soon as I can :) Just wanted to share this now it's all running!
