Some Thoughts: Power Supply

The interface requires a 5 Volt DC regulated power source. The IDE drive will typically require a 5 V and 12 V power source, or just 5 volts if you're using a notebook drive.

One of the cheaper sources of such power supplies are those found in PCs. By jumpering some wires on the ATX connector, you should be able to hook up such a power supply to the interface and your drive. The only drawback is that those power supplies are fairly big. If you're using the notebook drive option, you may find it nicer to use a 5 Volt linear power supply, wall-plug-style.
