DreamMachines

[BillionNamesofGod]

I did see something when I was a kid, a device called a dream machine.

Now I can see how this works, it detects REM and them, sends electical
pulses, which you feel in your dream, so hence you realise you are
dreaming.

has anyone had any use or can give some info on these machines?

I reckon any computer and software would do, what's needed is a way to
detect REM, and send some feedback to the user..

Has anyone seen any software?

Can a heart detector be used to detect REM?

Can a heart detector be used to detect REM?

I guess you need some kind of EEG system connected to the computer.
Maybe you can find some info here? :

Yeah I have heard of these, basicaly its a mask you wear over your eyes, that detects the presence of REM, when it does it flashes its LEDS, you than are supposed to see this some how in your dream and it sort of makes you realise you are dreaming, I dont think they make them anymore.

On a slightly different note (but same name) you may want to check this out too: http://www.10111.org/dreamachine/

Now, I haven't had a chance to make one of these yet (partly because my wife thinks I'm nuts for wanting a 78 record player to make one), but I have made a pair of LED goggles that flashes at the same frequency (which is adjustable as well).  I must say, it is a weird effect and could probably be use to get into a trance easily.

The Dream Machine what I'm talking about was, simple done by some
genius called Dr Keith Hearne, while doing his PHD at Liverpool University, in the UK.

It worked by having a thermistor (heat sensor) clipped to the nose, which I presume linkted to the hardware, was able to detect  REM, and then send a small electrical shock.

Actually, very effecient than tha nova dreamer, and actually supposed to always pretty much work.

Now, I think these days, it could be all done with software on a PDA, and you don't even need complex sensors, just a small thermistor heat sensor.
EEG is complete overkill -
All that's needed is just a heart rate sensor and heat sensor.

Just I wonder why with the success, Dr Keith Hearne stopped.
Does anyone know about Dr Keith Hearne?

Surely, he could easily replicate his Dream Machine in software now.

Heck,I'd give it a try, all that's needed to start I suppose is to link up a micro heat sensor, to you, and from that record lot's of nights sleep, and then you'll know from the charts when to REM starts, and when to trigger a mild electric shock.


Heck, I'm surprised we don't all have PDA wired to us when we sleep, if we are interested in OBE!

I don't know much about electronics, but I guess thermistor works like resistor. If that's true, it could be connected(with some additional stuff) to the line in connector on soundcard.
To detect heartbeat microphone could be used...
