Hi,
How should I proceed to make an activity tracker ?

- Accelerometer to track moves
- Store changes somewhere in JSON with axes and date

Should I store data in memory and download it by USB or should I store it on micro SD Card ? Do I need Tiny Clock to store time ?

May be it's a bad idea for TinyCircuits and there is already a dead simple product working offline ?

Thanks

I was talking about this idea with Ben, we are thinking about using an eprom shield instead of the SD card since the SD card can be somewhat power hungry.

There are some eprom / flash shields in the works
