Mind controlled gadgets? Answered
I was wondering if I could somehow design a simple gadget to detect pulses in your mind to turn a head mounted torch on and off.
So far, I am thinkng of putting metal pads onto your head, which would be connected to an amplifier of some sort. Since I am trying to detect Beta waves, "varying frequencies that are often associated with active, busy, or anxious thinking and active concentration." The amplified siignals would then be fed into an op amp active bandpass filter, to filter out all except that specific frequency. The output would then go into a switch of some sort. Would this work? Or are there some problems with it.
