Hi all.
With the recent discussions about censorship, and other issues such as unreliable power, etc it got me thinking.
Is it worthwhile for all us 4HV'ers to back up our collected knowledge onto something more substantial than the cloud, so that in the event of a major disaster we can at least rebuild the community?

I suggest copying all the useful files such as semiconductor datasheets, research notes, ongoing projects and suchlike onto non encrypted pendrives, then sending them to one of several geographically separate locations.
Copying over the Net is also feasible as long as file integrity can be guaranteed..

Any comments?

I've over 5000 semiconductor datasheets on my pc and the ability to run off-grid.

Putting all our datasheets in one cache would not help much, you need to have multiple copies buried all over the world to keep them safe - personal computing would probably punishable by lobotomy anyway.

In such a scenario protecting semiconductor datasheets would not be one of my priorities.

If you are really worried fill a few satelites with all known knowledge and send them into orbits that would make them accessible once a century/millenium etc.

I was thinking more in the event of a hypothetical 1859 level solar storm wiping out the power grid, or complete failure of the world's IT infrastructure here.

Having backups of things like medical knowledge, as well as improvised power sources would be incredibly useful and could save lives.
Sort of like how amateur radio can be used as a communications channel in the event of a national emergency situation.

Having datasheets around won't do you any good. It is not like they are the semiconductor masks or the actual designs. Even with the actual masks etc., the machinery at the fab are controlled by embedded computers etc and probably not going to work in your scenario.

Old textbook (dead tree edition as opposed to DRM eBook) on the other hand would be much more useful to rebuild/relearn "the world". They don't disappear with EMP. They are in University libraries, book stores and book shelves.

In case of an emergency, your priorities are food, water, medicine, weapons and communications.

Note: "The World" in B-movies always seem to be in North America (or their target market) and not globally. There is a good chance that the other side of the Earth might be okay.

while building your own semi's after a situation like this(or any other time) is impossible for us, what if we need to build some sort of device after a storm. maybe a radio? any you don't even have info on that rf mosfet you have laying around? i have experienced this sometimes when the isp is down. i am completely unable to advance in a project. sometimes i print out datasheets of parts i commonly use. i think this backup idea is a good idea, but not with flashdrives in one or a few locations. we would have to rebuild the internet to even be able to get everyone access to them.

My first 24hr+ power outage in a high rise building taught me that water, food storage/preparation and heating are my first priorities. Any longer, I would be in an emergency center. I was cooking ramen noodles using a penny stove with isopropyl alcohol for a recent 8 hour outage. ;P

If you can calmly actually sit down and build circuits, that means you are not in much of a "Planet of the Ape" type of disaster.

I hope you do enjoy working with butane soldering iron under candle light and powering your electronics with salt or vinegar batteries...

Start collecting parts for a vacuum system if you want to DIY your own electronics. Personally I'd forget MOSFET's, etc. and concentrate on valve (vacuum tube) technology.

(See recent threads on DIY vacuum tubes)

These would probably be immune to an EMP anyway.

The grid is only somewhat dependent on the communications/telemetry infrastructure.
It is designed to keep up provided supervisory control signals are valid. After that it reverts
to various degrees of stand down status. (steam systems are tripped, penstock valves close,
and dams open spillways.

With the controls destroyed, power dispatching can still take place, by reverting to
manning substations with operators and running the generation plants locally.

Fusion, fire, water, and rivers provides most of the electricity that people who
live in cities need to survive.

Hinterland dwellers do not really need electricity to survive. By the time the urban
sector could adapt outside a Northern city, most of them would be dead anyway.

Don't know about you, but my workshop has an intranet with a server that provides a version control system for code, and dispenses datasheets and other documentation.

The datasheets are on the server because, in this day and age of DatasheetArchive.com buying their way to the top of the search results and making you click through three pages of ads, it's easier to host them locally.
