For the to to I'm about to build I need 18 servos 2 dc motors and a couple ultrasonics but as far as I know the ez board only has 20 digital I/O's and it looks like the motor controller takes 5!? How and can you add more servos controls? And can the program control more then 1 board?
However, I would try to balance the load over the two boards as much as possible.
I also am running external power to one heavy duty servo and will be adding two more later. You run you're external power supply direct to the servos. You can even install a 5vdc relay inline and have EZB control it with a script. That way you can turn on and off the power to the servo only when you need it.
Have fun,

As far as the servo, I only have one being used so far. The remaining motors I'm using are all DC motors controlled by EZ-B through H-bridges. That servo is a monster top end servo and I'm using it for my bubble lifter. It's a Seiko UAV servo PS-050 bought from:
troybuiltmodels.com
It has 5 wires; Two are for Pos & Neg power wires and three are for RC or Microprocessor control. In the case of EZ-B the last three would go to the digital port (Ground, 5vdc, Signal).
On a regular servo with only three wires you need to attach:
The Data wire from the servo to a Digital Port Signal pin on EZ-B
The Power wire from the servo the Power Supply's Positave
The Ground wire from the servo to both the power supplys Neg and EZ-B's Digital port ground pin
Something like this:
Hope this helps,

A 2.5' Rambler-Crane series Robot (B9) will be just fine and a real blast to build. What are you using for a platform? Have you found a 2.5' LIS movie robot? Please keep us informed with your progress with pics or vids.
I got the sound files from two CD's that are sold by venders on the B9 Builders Club. Craig Reinbrecht sells one called I_B9 and is Interactive Phrases and Voice Software for your B9 Replica. Daniel Monroe sells one called Robot Ramblings and is a 3 CD set of OVER 340 licensed Robot B-9T Phrases. Dan can be a little slow on delivery. A lot of members have waited months for their CD's but he seems to always come through. See the links below:

Have fun!
Also the I-B9 software is interactive so you can point and click on the phrases you want to him say. You can also build your own custom words or phrases out of the large selection of included files and play them. Most of them were recorded long after the original show ended and custom recorded by Dick for this CD. You've never heard most of them on either the show or movie. A lot of work went into the production and re-mastering so the voice sounds just like what we remember from the Robot. It's actually a one of a kind work of art and well worth the money. Even if you don't have a B9 robot. Very fun to just play around with on your laptop
The CD's offered by Dan are also remastered in the same way I mentioned above but clipped straight from the show. All three seasons. No background music or noise.
A lot of work must have went into each.
Have fun!
