I am looking into building a system for my truck that works like an aircraft black box, I was wondering if anyone had an idea on how or what I could use for enclosures that would protect the data from fire, water, and impact
This is for an 18 wheeler truck not a pickup
Same stuff that are used in building Security Safe's maybe??
Google "aircraft black box", and you'll get lots of information. Some of the links should lead you down the right path. For example, here's a link that describes the black box system: http://science.howstuffworks.com/tra.../black-box.htm. Page 7 provides an overview of its construction: http://science.howstuffworks.com/tra...black-box6.htm
I have thought about one of the small doc safes but wonder if they would work, Paper actually takes quite a bit of heat to combust, where as I have seen sd cards destroyed sitting in a hot car in the sunlight,
The other consideration is the fact that moisture would be and issue. I did find that IO Safe has some reasonable Fire and water safe drive enclosures but I wonder about impact.
I have used some older solid state drives or at least used equipment with them installed, but for some reason even units no older than a year or two failed because of lost O.S data, Trucks have a lot of vibration and hard jars. They also continually change in Temperature, Pressure and moisture. and of course they have fairly large power fluctuations.
Truck engines take a lot of power to turn over so even with four batteries when cranked voltage can drop down below 10 volts and at charge as high as 14 volts.
I have went through some pretty expensive technology in under a year before. most of my laptops do good to last two years and that is with at least one power supply replacement due to the invertor.
Ive actually thought about a system that would compartmentalize all of the system.
Yes heat will be an issue definitely, not sure how you can overcome this TBH.
