Journal Chacham's Journal: Homebrew brain wave readers 1

I posted this to AskSlashdot, and it was rejected. *sniff* Anyway, I've been having a hard time finding information on this. Probably because I don't understand what key words to search for.

There are devices that read brainwave activity, and can be used to do different things, depending on the sensitivty of its readings, and the user's control of it. There seems to be three types of detectable brainwaves, and two of them can be controlled relatively easily. With that, a device can be attached to the subject's head, and, for example, it can be used to move a mouse. There are a couple commercial products availible. I believe one was called, BrainFingers. They cost between (US) $1,000 and $2,000, so are quite expensive.

I have heard, and was once shown, that there are ways to build devices yourself for much cheaper. I guess I'd also need a driver for Linux. I was wondering if there were any active projects in this regard, or if anyone has good information on this subject.
