Two-electrode low supply voltage electrocardiogram signal amplifier

so our professot asked us to do understand it in general and in details, but I nearly understand nothing (unfortunately ) even though i've tried so much...

Hiya 4electros,
Siliconchip magazine did an electrocardagraph project lat last year. On reading the project I found it to be very informative and this could be just what your looking for. I don't have the mag handy at this moment but if you like I can scan the article and e-mail it to you but I have to do it in the next day as I'm heading off to the bush for work in 3 days and I'll be offline while I'm away.

Cheers Bryan

Hiya 4electros,
Here's the link to the project which shows the start of the article http://www.siliconchip.com.au/cms/A_103787/article.html
I don't have the february mag in the house and it's a bit late to venture up to my shed to look for it so I'll scan it in the morning for you. Anyway that link will give you a quick look at the article.

Cheers Bryan

Hmmm...
The link comes up on my screen as

http://rapidshare.de/files/9807790/e...ifier.pdf.html

I think the ellipsis is screwing it up. I get a "file not found" message, and it goes to the Rapidshare main web site.

Nice one!.

But is it just me?, Feburary 2005, and Silicon Chip are still publishing designs using the ancient 16F84 :?:

Even worse, they add a buffer chip, an R2R ladder (perhaps someone on these forums ought to have a look at it? 8) ), and a comparator to make an A2D converter. They could have use a PIC from this century, like the 16F819 or 16F88, and saved all those parts!.

I think some of their projects sat in their files for a few years before they released them.

Thanks for that tip Audio now it will save me from having to scan about 10 pages :shock: . Just a side note on Siliconchip, I've been buying the mag for just on 3 years now and the mag has gone down the same road as most other hobby mags- 1/3 of the mag is adverts and the majority of the projects are designed where you have to buy a kit at a huge price which does take away the hobby aspect of electronics. Take the scoreboard they did last year, it's a top project and a very usefull one at that but who can affort the $800 price tag they put on it :shock:

Cheers Bryan

Prices are high down under because there isn't enough competition.

The share site wanted me to pay and to upload something. I couldn't find your file there.

Why bother uploading files to a share site, then ask us to bother going there. Why not simply attach the file to your post here?
