Sound card ECG with AD8232

Monday, March 18th, 2019

Scott Harden built a DIY ECG project with AD8232, that is available on Github: Every few years I revisit the idea of building an ECG machine. This time I was very impressed with how easy it is to achieve using the AD8232, a single-lead ECG front-end on a chip. The AD8232 is...

DIY ECG with 1 op-amp

Monday, August 8th, 2016

A DIY ECG made from single op-amp (LM741) and 5 resistors by Scott Harden: I made surprisingly good ECG from a single op-amp and 5 resistors! An ECG (electrocardiograph, sometimes called EKG) is a graph of the electrical potential your heart produces as it beats. Seven years ago I posted...

Minimal ECG using an Arduino and Xoscillo

Tuesday, July 9th, 2013

Raul  from Coding Laboratory has designed a DIY ECG project using an Arduino and Xoscillo: To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope.

Simple DIY ECG + pulse oximeter (V2)

Tuesday, April 16th, 2013

Scott Harden has designed an ECG/pulse oximeter combo project using LM324 op-amps. Scott describes, "This new project is fully documented and uses extremely common and cheap parts, all of which could be purchased at RadioShack. It serves as both an ECG *and* a pulse oximeter, depending on which leads are...

Arduino mindreading library

Thursday, August 11th, 2011

Chris from LVL1 Louisville's Hackerspace has been working on hacking brainwave sensors using the Arduino. Both the Force Trainer and Mattel MindFlex use a daughterboard from NeuroSky that outputs serial data for values of 'Wireless link', 'Attention' and Meditation. Both of these devices have the same NeuroSky board, so the...

Do it yourself heart monitor

Wednesday, July 20th, 2011

victzh posted picture of his DIY ECG using an Xprotolab mini-scope/logic analyzer in the project log forum. Some time ago I bought an excellent toy - Xprotolab mini-scope/logic analyzer by Gabriel Anzziani. I touched it signal legs, and immediately saw that it picks up 60Hz through my body. I looked around and found couple...
