Electronic Sleep inducer

Hi all,

My name is Michael Youssif and I am performing my final year graduation project in the Biomedical Engineering Technology program. My project is a sleep inducer circuit that will be connected to an EEG that will be done by one of my friends. My sleep inducer circuit is at the following link: http://electronics-free-projects.blogsp ... ducer.html but the problem is that I need to use the raspberry pi instead of the NAND gates and the timer and ripple counter IC by taking the push button P1 as an input to the r-pi and the output will be the radiator coil L that should produce magnetic field to help the patient to sleep. So, does anyone know how to connect the r-pi to the circuit and what type of software to be used? Also, how to write this software on the r-pi?
Also, please inform me if the r-pi can be used as the connection between the sleep inducer circuit and the EEG.

Thank you very much for your help in advance.

Regards,
Michael

Actually fairly simple to connect the transistor Q1, diode and coil to the Pi. Connecting a button is just as easy too. The program should only be a few lines, so nothing special. Getting that 60uS pulse accurate is more of a challenge - there will be some jitter but I'm not sure it's that critical, is it? It's just a very short pulse through the coil...

No idea about the EEG - probably - but it all depends what you need to send to the EEG.

But won't it be easier & nicer to put this in a little box to go under the pillow rather than a relatively big Pi that would need connecting to mains power to keep it going all night?

I was going to suggest the X-Factor...maybe not what the OP was referring to though.

Beer and boring TV usually works for me like a Woody Allan film, Celebrity Big Brother or Newlyweds. :)

On a serious note does such a device really work??
Many people experience sleeping well in natural surroundings, into a tent or a wooden hut.
To be honest I think people sleep better outdoors because of the fresh air and cool temperatures not because of the lack of magnetic stimulation.
I never sleep well in warm stuffy conditions which is why I find leaving my bedroom window open in the summer a real help.
There are other factors too that can disturb sleep i.e. sleeping next to mobile phones (electromagnetic interference from base station polling). After sleeping for years with my phone nearby I can't say I've really noticed any problem I guess some people sleep better than others.

Aside from timing issues - there seems to be four: 60ns for the pulse, 1.2Hz (0.83s), 5Hz (0.2s) and 15/30/60mins, and Linux could find the first difficult - the interface to the coil should be straightforward, and switch inputs likewise.
However there doesn't appear to be any details about the coil!

My other thought is
our unconscious ability to perceive natural Earth’s magnetic fields. Our mini project generates this type of Geo-magnetic-fields
How is 60ns pulses at 1.2Hz / 5Hz natural?

am making a sleep inducer as well for my final year project so I was wonder if you can help me out with some stuff on my circuit.

Neither of the 2 previous posters asking for help have revisited the forums. Perhaps they fell asleep waiting for a reply? Works well doesn't it?

As if such a ridiculous gadget would work anyway.

If you want to get to sleep with electronics I recommend Horowitz and Hill: The Art of Electronics

If inducing 60us pulses every 200ms helps those kept awake worrying that "Wi-Fi gives us cancer"; it can only be a good thing :P :P :P
