Hi all.
It occurs to me that many 4HV'ers often need copies of common datasheets for often used IC's and transistors.

Is it feasible to have a small area of the server (or someone else's server) dedicated to hosting these?

the main issue i can see would be malware, but most of the manufacturer's sites are "known clean".

Upload/download requires login as normal (to stop leeching of bandwidth) but otherwise simple.
comments?

They could use some existing database such as

...

For vacuum tubes, they could use

The links don't always work for sites that changed their database format. For that's supposed to be on NJ7P, I normally go to their site and search for the tube there.

Ya, that's what the Internet is for.

I recently set up a server in our lab that, among other things, dispenses datasheets for our commonly used components over our intranet. It works remarkably well, you just point your web browser at the datasheets folder, and enter the part number in the browser's find function. Most browsers almost instantly display the PDF in a tab.

Every part that I've ever looked at - I keep the datasheets in a structured set of folders on my SAN. This includes all old values & tubes, old manuals, books etc.

Every piece of s/w I use is also kept on the SAN (current and some historical versions), top level directory is the manufacturer, then each of their products under there, including key files etc.

I then created a web site than indexes both the datasheets & s/w, and serve that on my intranet.

Saves a HUGE amount of time and can be accessed anywhere (external VPN portal).

Requires a bit of discipline though...

Cheers

heh, this works well.

Have you considered mirroring your archive so other people can view datasheets?
maybe we can ask chris about adding this feature to the wiki?

It has been kicked around, but the general consensus has been that it's easier to just Google up the datasheets. I'd also wonder if there are any potential copyright issues with redistributing datasheets.

I've always found the free Datasheet Archive invaluable in finding data on semiconductor devices.

And Frank's Electron Tube Pages to be the single most comprehensive source for thermionic valve datasheets, though it often lacks data on some of the more exotic and long obsolete types.

There are a good many Russian datasheets out there on the web, which can be tricky for the newcomer to navigate, so I would support a special repository for these and other hard-to-find data sheets for exotic thermionic valves, vacuum capacitors, vacuum relays, thyratrons, x-ray tubes, GM tubes, and so on.

Half the battle is *finding* them

copyright may be an issue, but most manufacturers are fine about copying/etc as it saves them bandwidth.
One to watch out for is Electronics Digest as someone owns the rights to that and does go after people sharing it.

If all else fails sending out a disk full of goodies might be an option, costs very little to post and you have a physical copy in case the pc breaks down.

Schematics are another matter entirely, best to avoid those unless the owners of the rights are ok with distributing them.

Doing this for personal use is fine - trouble is that most of my interests lie outside of HV, so the bulk of the archive (now over 20,000 documents) would have no relevance.

Frank's archive and the many other good repositories work well - just build your own collection. I use digchip.com as well as alldatasheets etc. They all help, as do individuals who scan stuff and exchange data.

Everybody's requirements differ.
