Can't the writing be delayed?
Perhaps, but at the risk of losing the data.
Linux never crashes :-p
Of course not :-) , but the power might disappear.
Bring an UPS line to it from somewhere else?
It totally ruins the idea of a neat and tiny device being hidden away in a corner. The ARM board is only 50x50, the power supply is already bigger than the board :-)
I know, but you have to connect it to the mains. Bring a mains line from the house that comes from an UPS :-) (Years ago I contemplated running a 12 volt line on the house...)
These tiny computers can probably run directly from a battery, that could be charged on standby.
The project is growing :-)
:-D
Or... have a huge capacitor, and on power failure issue an emergency write everything order, then halt.
Yes, I have actually wondered about that, using a supercap. I think I'll stick to writing to the SD card.
Tsk tsk... I was looking forward to the photos :-D - -- Cheers / Saludos, Carlos E. R.
