I am planning to build a project around https://www.sparkfun.com/products/12650 to take an ECG while I am on a roller-coaster (not for medical purposes, just for fun).
The following points are (additional) requirements:
To capture the data, I need to write them onto an SD card or some other memory device.
The device should support wifi so I can have a live feed on my mobile phone. So one possibility would be an ESP 32 or ESP 8266.
Another great addition would be an acceleration sensor…
Because this should be useable on a roller-coaster, a power bank for mobile phones (except for very small ones) and a stationary power source are both not useable. The power source (maybe a battery?) should last about 12 hours. If this is possible with a small power bank, I will use one of these, because I can ignore the protections against discharging and such problems completely. So that decision depends on the energy consumption of the build and the possibility to use an USB cable for connecting the two.
The whole device can not take up a lot of space (it should fit below my shirt or so, to not fly around freely, I will 3D print a casing).
I experimented with ESP and raspberry pi before, so I know how to program and connect additional devices to them, but I never used something from SparkFun’s “ecosystem” before.
To come to a conclusion, it would be great, if you can help me finding the right parts for that project.
I am waiting for your answers and hoping, that you can help me
This isn’t really Technical Support or what it is used for, but I’ll provide some info to get you started…though it might be best for you to look at other similar projects and tutorials to gather your shopping list, and use SparkFun’s product offerings to assimilate the project. Figuring out what is needed for your project is something you will need to complete.
They are MANY ways for you to accomplish what you want, but the ideas need to be organized.
