Hi All
I have build an EEG machine similar to your design, with microcontraller tocommunicate with the computer (PIC16F877 Upto 8 channels, only 2 channel use at the moment expandable to 4 channels) through serial port with an optical isolator (4N25 if I'm not wrong 5000V isolation) . and at the moment Iwrote software to for the data collection and display only. filtering partwill be added soon.
I'm designing this for one for the nurofeeback therapist. he wants a cheap and safe machine for his clients. I'll be writing software according to hisspecs. He want about 10 units first.
Now I'm in a process of finishing PCB and fine tuning software and circuits. As soon as I finalize the PCB I'll be making about 100 pcs because it's cheaper to do a lot.
I found a person who can make probes He will be sending samples soon. if his probes quality is good enough I'll be using it. Its very cheap.
This machine will cost less then US$150. (With packing user guide and everything. Cheaper version may be less than US$100).
If any one need a assembled one I may be able give few units for cost.
