Make your own ECG Machine on the cheap

For those interested in measuring their heart activity with an electrocardiograph without bothering a hospital may find this project of interest. By using some really inexpensive and simple circuitry connected to a PC with a sound card, Scott Harden has designed a simple ECG system that can measure and analyse the heart data on a PC using some Python code. In the following video watch Scott run through his ECG:

Considering the total cost of the hardware for this project would be less than $20, it could be a lot of fun. So to get started, visit Scott's excellent website here. And for more news, updates and items of interest.please follow us on twitter, Facebook and Google+.

If analogue electronics is new to you, or you're interesting in brushing up your knowledge in order to be able to design your own analogue-digital measurement systems, get yourself a copy of "Electrical Engineering 101" by Darren Ashby.

Over 320 pages there is everything you should have learned in school, but probably didn't! This book is great for electronics newbies, or if you just need a refresher course. Topics ranging from Ohm's law to proper usage of an oscilloscope to managing and interacting with employees are covered. The book approaches all of its topics in a very straight-forward, practical manner, and all the important information is summed up nicely in a "Rules-of-Thumb" section. The information presented in this book will provide a great start towards building or reinforcing your EE knowledge. So order a copy today!
