Am I right in thinking you want the power to the servos to be 6V (or whatever) and not supplied by the VCC and Gnd of the EZB?

If so, I mentioned a board I made the other day. Very simple too, a small piece of strip board, +6V and ground feeds 2 of the tracks, these then have the servo extensions soldered in to the tracks also (from the female socket end), the male plug end is untouched and plugs in to the EZB for signal.

I did draw a PCB design for this (with 6V regulator) but it's at work and I wont be back until Monday. If it's unclear I will try to sketch it out for you.

If I have misread or misunderstood then ignore that

@Rich.

Yea thats what I was looking for. Dang as soon as I read your reply I was pissed I didn't remember reading that.

its going to come off the same 12v battery so there won't be an issue of floating ground.

I found a place in Ontario that can make PCB's for me but I have to make the drawing for them. What software would you recommend to make a PCB drawing?

Yep nice and simple. I am going to build it with one of my bread boards then see if I can get some PCB's made to clean it up for the final build.

ExpressPCB is great, easy to use and you can even get them to make the PCBs (expensive for a one off though).

If it's 12V you will want a 6V regulator circuit before the strip board, although I'm sure you knew that but others may not I use a LiPo one, but it will work on anything, 5A 6V is plenty for my build. This is the one I use

Just found ExpressPCB software so it looks like it will do what I need it too.

It's also great for schematics too and you can link schematics to PCBs (although I don't but I rarely make PCBs due to the high cost, stripboard, proto board and bread board (anything with board after it) works just fine even if it does look messy with flying wires all over the underside.

ExpressPCB for anyone else who needs it. It's free too which makes it so much better.

Yea thats what I was thinking of finding a already made regulator and mount it. I don't mind having a couple like one or two regulator/supply for each arm.

The reason is I am not sure what its going to take current wise to just run the arms and speed and I just lazy to do the math.

As mentioned somewhere (probably my Hearoid topic but this is better than there), the PCB design I knocked up. It's not tested so use at your own risk. Made using information found on manufacturers sites, feel free to speak up if it's wrong.

No schematic yet, I should have chance to do that tomorrow.

R1 is a 1ohm 1/4 watt C1 is 0.33uF Capacitor C2 is 0.10 uF Capacitor Voltage regulator is a TS7800 6V 1.5A Regulator L7806CV.

The LED and R1 are optional, there was space so I used it.

The Voltage Regulator is only rated at 1.5A.

Board is 1" x 1"

It should be able to take up to 35v DC and supply 6v DC to the 5 servo points. You could increase or decrease these depending on servo current etc.
