I was looking around doing a little research on the wiimote camera and ended up at the Make website, and saw this article

http://blog.makezine.com/2012/03/05/make-a-mind-controlled-arduino-robot/

pretty interesting stuff the sensor works over blue tooth, you can fine an intro kit here for $99 bucks http://store.neurosky.com/products/brainwave-starter-kit i had no idea this technology was so cheap now.

    That is quite cool. I wonder if anyone here can show us how to do this with a Prop or Stamp????

    I'd buy that book. On the link the book says $4.99 but when you click on it it says $7.99!!!

    Jeff (OBC) experimented with a "Jedi" mind control toy and I've experimented with a different type of these mind toys (Mind Storm? Mind Flex).

    It's tough to get a clean signal with cheap sensors. I think there are a few devices that may work well but they cost more than $99.

    This is still a field I find very interesting and hope to do some more experiments with my headset but a joystick is much easier to use than trying to get you brain to behave in a predictable manner (I suppose I should just speak for myself, maybe other peoples' brains are better behaved than mine).

    I was getting very excited about control via brain waves, but it seems the most successful systems to date have surgical implants on the surface of the brain. Not exactly a DIY project, but very feasible.

    Are you ready to go under a knife for the sake of research?

    If I ever get $300 and some free time this is the one I have my eye on. No surgery required!

    I was told that the sensors are very easy, just need instrumentation amplifiers, its the software that irons out the wrinckles in the cerebellum that is the tough part. But it seems this product has that solved, or at least a very good start.

    It was the Starwars "Force" trainer and was very disappointing.

    Here's the video from the project. Jury is still out on if it was actually reading my brain. Heck, jury still out on my actually having a brain so who knows?!!? :)

    My advisor has some of the mind flex devices.
    I'm not totally convinced it senses anything.
    We have been intending to take one apart forever, but never got around to it.

    This was my first impression too. However I found whenever I'd concentrate on the building instructions the "concentration" parameter went up.

    I tapped into the raw data from it. It's missing some of the parameters the neurosky device outputs (I think they use the same module). Part of the output is a "signal quality" parameter. I noticed this parameter was generally very low.

    This thread is making me want to dig out my hacked headband again.

    Maybe visit your nearest Nerologist and ask for some of their high end connectors to use. If it is for research they might just give you some. Use those with the $99.00 package to see what happens.

    I think NCC has a great idea! Im gonna be onest after watching jeffs video im not buying it, if thats how they all work. There were game controllers on the market you could use to control yor games with forehead stress detection or something like that, I think these may be in the same family of devices they sure look a whole lot similar.

    In 2011 we did experiments producing versions of brain wave monitors that could read thoughts of a Propeller based brain. It was possible to harvest brain voltage, save patterns with an iphone, and implement virtual strip chart "thinking" recordings on a Mac. In some novel examples, the monitor could determine what the chip was doing by examining the "signature brain wave patterns."

    Given the chaotic state of my brain most of the time controlling by projects with it directly seems like a really bad idea.
