The issues are expense and your input voltage. One for each servo can turn into a huge amount of money. All of the inline voltage regulators will only step 6v or 7.4v down to 5 to 5.2 volts that I have run across.

So, would those be able to step down a 12v current to a 6/7v current? thanks!

Those are designed to step down a LI-po 7.2 volt battery to 5.2 volts. They will not work for a 12 volt battery.

So is there any kind of regulator that will bring down a 12v current to a 6v/7v?

Everything you asked for in a converter is in the first link Doombot pointed you to. With that unit you will not have to solder or even use a volt meter to know how much voltage your outputting. It's small also 2.5" x 1.5".

Input Voltage: DC 4.0~40V Output Voltage: 1.25V~37V Output Current: 2A(normal and stable), 3A Max.

It that unit is too big then the Pololu converters are great units. Cant go wrong with Pololu. However you'll have to learn how to solder to attach the header pin. You'll also need to get the proper Molex connectors or jumpers to attach to the header pins. Some people like to solder the power wires directly to the board to avoid using connectors but I think that's a bad idea. How are you going to disconnect if you need to change something.

A word of advice and I don't mean to seem condescending. If your planning on building robots you really need to learn how to solder and use a multi meter. The robots you will be able to buy through the store here at EZ Robots will be mostly plug and play. However if you plan on building your own from scratch or other platform you may need some more advanced skills. Learning simple soldering and a basic understanding of electricity and electronics will open many doors for you and take you on some real cool journeys in robotics. Youtube has thousands of vids on most anything you will need to know about these two topics. At the Instructables website there are millions of tutorials also.

And it so rewarding and fun! Isn't that what it's all about anyway?

By the way Current is Amps. Voltage just pushes the current through the circuit.

Good luck, Dave Schulpius

Thanks. I'll be getting those soon. It looks like all you have to do is strip the wires and put them in the in port and screw them down. Am I correct?

Yes, very easy. Just be careful when you tighten down the set screws. Hold the connector with your fingers when you tighten it down and don't over do it. It's easy to twist the connector and crack the solder joint underneath. If that happens you will have no or intermittent power. The only way to fix that is to reflow the solder joint.

EDIT: one more thing. Make sure you don't attach anything that will draw more then 3 amps max to this unit. If you do you will burn it out. You may need more then one if your servos (all added together) draw more then this can provide. Think of it like sucking all the air out of a plastic bottle. If you do this and make a vacuum the bottle will crunch.

One more quick question: there's 3 wires, but two ports. Do I just put 2 wires into one port and one in the other?
