I would like to power 800 servos at once for an animation project.
Do you think this would work instead of my 12v wall transformer?

Alright you can relax I'm finished for now.

Hi,
   I will lend you my multimeter, you can climb the ladder and check !

Duane, I'm really looking forward to using your code when the rest of my Quadcopter arrives!
Have you updated any of the old code to work better with your new 2.4ghz remote?
But seriously, I am hooking up nearly 100 servos...

Hi,
   If you really are planning on driving a large number of servos, have quick look at the servo current draw comparison here  -

http://rcarduino.blogspot.com/2012/04/servo-problems-with-arduino-part-1.html

The Bluebird servo draws over 5 times more current than the Futaba at idle, thats going to kill your run time and need some serious batteries.



I plan to measure the current under load in the next few days it will be interesting to see whether the difference at no load carries over to load currents as well - I expect it will.

I have done little more work on reading RC Channels using the PinChangeInt library to read three channels and four wheel speed sensors here -

I will post the code in the next few days.
