Overview
Here are notes for myself and others interested in building DIY ECG equipment. There are many ways to skin this particular err.. project, from crude to incredibly complex. Here are lists of parts, websites, theory, etc.
Page maintained by User:Obscurite who is working on his own ECG equipment. Enjoy.
PARTS for higher-precision version(s)
- Instrumentation Amplifiers (not sure why these are priced so differently)
- Better op amp - OP97 (need to review data sheet)
PARTS for basic version(s)
- LM358 (dual opamp) or LM324 (quad opamp), or LF353 (which is pin compatible)
- Diodes
- 0.1uF capacitor(s)
- Variety of 1/4 watt resistors (10k, 100k, etc)
- shielded wires for electrodes (phone or coax cables)
- electrodes (soldered pennies, medical electrodes, etc)
- diodes (1N4001)
Microcontrollers and FPGAs
- Atmel atmega168/328 has onboard ADC
- Xilinx Spartan3E dev board has built in ADC
