Hi there. I am building some sort of project like yours and I am having some problems. I think you can help me out.
I have my circuit (a simple INA114 with Gain 10 and another op amp to give me the rest of the gain I want) working fine when I connect it to a simulator, but it gives me no response when I try it with real people.
I found, then, your project and I decided to assembly it just to test and see if my circuit had any problems. Same thing, the oscilloscope shows a fine signal when it is connected to my ecg simulator, but when I test it with my own thumbs I get no response at all.
I am using, as electrodes, 2 small copper plates, just as I see you use on your project. Sometimes I try with commercial electrodes too, but nothing changes.
Do you have any hints on what my problem could be?
Any help is appreciated.
Thanks
And nice project by the way.
