wearable mobile ECG system - how to?

[joe50]

Hi Guys,

I wanna use the Olimex Shield EKG and 328 Boards as a mobile ECG comparable to the openBCI boards or similar.

For that I need:

A power supply: this seems easily manageable with a LiPo 3.7V battery and the JST connector on the Olimex 328.
data storage: Is there any way I can save the data on the board while recording it (like a SD card) and transmit the data after a workout to the computer?
Control: How can I control the board (start or stop) when beeing in the field? I obviously cannot control it through the ElectricGuru.

Thanks for the inputs guys!

One option would be to use a data logging shield with stacking headers, such as the one pictured here:https://www.adafruit.com/products/1141.  Some liquid crystal displays can also log data using a microSD memory card.

Possibly could use buttons on an lcd to start and stop a process.
