hi man
nice , nice . sounds very interstin .
can you share specs , and maybe schematics ?
if you post your communication protocol , we could ask rob sacks to
make electric guru software work with your machine . interested ?
2 questions about safety :
1. tell us a bit about your input stage design .
2. would it be posible for a talented designer like you to make a
little change and instead opto coupler isolation ,
make fiber optic based isolation ? it's surely safer , and surely
more marketable as safer this way .
we have a design of this , it's very simple .
by probes you mean electrodes ? how cheap will they be , and what
type they are ?
about software , is it closed source ? or would you like to make it
open source , as a base for our software development , and then
people will probably help you write code .
by the way , which country are you from ?
would you like to be in the business of selling assembled and tested
devices throught net ?
sincerly

microcontraller to communicate 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 I wrote software to
for the data collection and display only. filtering part will be
added soon.
