Hello,
I'm in dire need for Electronics World Magazine October 2007. There should be diy ECG, I'll try to convert it to PIC18F and send data trough USB. Since I'm not with analog exactly on best terms it would help tremendously if someone could upload it.
Thanks
If you call 999, they'll arrive with one that's already built and switched on...
And where would be fun in that, especially from my side... :]
FWIW analogue ECGs are fairly straightforward, googling should get you lots of very similar circuits.

Well yes and no, instrumentation amplifiers are not to complicated discrete or not, but problem is noise, even with low pass filtering and notch I'm not receiving any useful data. Before I pass it trough DSP on uC I would like to get most of analog. I did scourge the web and there isn't much more to find, expect this magazine. Maybe it would help and give me an edge over other concepts.
I took some bioengineering books, there are many options to eliminate noise but I'm simply not comfortable with them, for example forcing a weak current trough body and others potentially dangerous interventions.
