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...MichaelYoussif wrote: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.
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.Many people experience sleeping well in natural surroundings, into a tent or a wooden hut.
