I need to create a 6V DC power supply to power a pipe locater. The input voltage will be 12V DC supplied by a deep cycle battery. The power output is approx 2 Watts, but for the sake of safety the circuit should be able to provide 4 Watts or .66 Amps. I am fairly handy with electronics I'm just not familiar with voltage regulation. Any tips and advice would also be greatly appreciated thanks in advance.

I'm looking to have a rapid prototype made for a product I'm working on. I can't seem to locate the resources online. I'm thinking either CNC machined from plastic? Maybe one of those laser prototyping machines with the vat of liquid? Heck, even a plastic printer? Any ideas anyone!

I need to find a cheap, reliable electric pump to buy that can pull water from a fishtank and put it back in. It doesn't need too pump very much water (will be operating out of a 1-2 gallon tank). Cheap is the biggest requirement, because I need to buy 4-5 of them. Also, I need it to run on DC, and needs to be able to take varied voltage input. This is because I have a program controlling the speed the pump goes by increasing or decreasing the DC voltage output based on other variables. I am using it for a science project. Thanks to people who answer!

I am interested in SETI, the Search for Extra Terrestial Intelligence. I do not have a career in astronomy, so there is no danger of adveresly affecting it. I know how to program FPGAs to do FFTs, how to design antennas, RF preamps and other aspects of the electronic arts.
How could I best aid this effort? Does it need more funding, more ideas, more manpower, or what? How should I best deploy my talents?
