Hi-
the site seems to be down- very sad, beause it had SO MUCH valuable information.. :o
I just wanted to build a SLR driver for my x-ray untit according to the shematics and description there: http://www.stevehv.4hv.org/ccps1.htm but now...
Anybody an idea if the site moved? Is there a mirror or is it somwhere archived at least???
Or does anybody have the info that was provided there?
Thanks a lot!!!!!!

If you mean the 4hv site, the site is "working" for me. By "working" I mean that you still can't post images but you can still access all areas of interest and view the postings.

I have been in contact with Steve Ward and his tries to get it back online.
I might also host his content on kaizerpowerelectronics.dk if I have the time to add it

I’m constantly using the waybackmachine ever since I started anything high voltage and constantly see more sources disappear or turn into spam websites

Bradselph beat me to it, Steve's website and a number of other coil websites are on the wayback machine.

I use it all the time when I'm reading something and it references another webpage that's long gone.
i wouldn't have gotten as far as i have without the waybackmachine.

Its a real shame that a lot of the old tesla coil websites are slowly going offline. Richie Burnett's website has had broken pictures for the last year or so. If you know about the websites you can find them from the wayback machine, but the chances of finding them for someone new to electronics / tesla coils is pretty low.
These websites are still some of the best websites for tesla coils, especially for proven designs and theoretical insight, and had a big role in getting me into electronics.
It seems a lot of the tesla coil stuff nowdays has moved to facebook, which is a real shame. Its a lot more ephemeral and the average quality is a lot lower. With the recent popularity of the "slayer" exciter the average tesla coil complexity has probably even gone down....

Richie's site works fine for me. Here is the link that I use.

Lots of HV sites have been going down in the last few years, and the wayback machine doesn't always have the full sized images saved.
What'll happen in the future? More and more of these sites slowly go and the information gets scattered and forgotten as people move on to other hobbies. I think those slayer circuits became popular as they don't really require much tinkering and can be made small out of scrap, once people have had their 5 minutes of hv fun and posted the pics on social media they can put it in a drawer and forget about it.
I don't know what I'd do without hv websites and forums like this, I often forget what I've learned and have to keep coming back for information and reread my old forum posts.
So what is going on with these .4hv.org subdomains? There was uzzors2k and the datastream I tried accessing but can't get on them either, both were full of information which I regularly look at.

I have secured backups of stevehv and thedatastream, uzzors2k I did not have. I have an agreement with Steve Ward to repost some of his content on my site, so if you have specific wishes please do ask them here, else it will be the universal drivers, interrupters, some DRSSTCs and the CCPS since it was asked about here.
I did the first repost of UD1.3b last night: http://kaizerpowerelectronics.dk/tesla-coils/universal-driver-1-3b/

Lets just hope the Internet Archive (host of the wayback machine) manages to stay in business:

Before I knew the wayback machine I used WinHTTrack - and still do for things where wayback is not practical. This free program allows you to create a complete and fully working offline copy of any website including all of its content. The only things that it can of course not download are scripts that run on the server (like search functions) and streams (e.g. youtube videos). For the pages discussed here it is perfect.
I have complete offline copies of Steve Wards, Richie Burnetts, loneoceans and other websites. Unfortunately I can't share them since I do not own any copyrights and afaik none of the informations were released under a Creative Commons license (or similar).
While this doesn't help for sites that are already gone, maybe some of you'll create their own copy of the sites that are still available.
Kind regards,
Max

Use unencrypted connection (http://) to Richie's site. For some reason the images do not load if you use encrypted connection (https://).
Does anyone know if 4hv wiki is still available somewhere?

Ugh, legally the publishers have a strong case, morally and ethically they should abandon the law suit.
If this was say a national library doing the same thing, the publishers wouldn't even consider a lawsuit.
The Internet Archive is the only copy of some former websites, and other defunct digital content.
It should be protected in law, but it isn't.
If we didn't have a bunch of technophobes and cynical old men in government, the IA would have the protection it needs.

I spoke to Chris (who runs 4hv.org) several weeks ago, and he was having some technical difficulties with the site at the time. It seems most of it is up and running again, and Steve Ward's website appears to be working also. My website does not seem to be online however, so I purchased my own domain name and moved to a different webhost. You can see my website at uzzors2k.com (http://uzzors2k.com) from now on.

Good to hear from you! and welcome on HVF :)
Great to see that you have an updated site and make an effort to keep sharing your content!

Good to see you Eirik. Is that the same Lego man as in your 4hv avatar image, in radiograph form IIRC, from more than 10 years ago?
My own DIY x-ray experiments never bore radiographs. Then I got a couple of complete working dental x-ray generators, which removes the HV exercise from quantitative radiation measurement and photography.
-
Thanks for the warm welcome guys. ;D It's a great site you've put together Mads, and seems to be very much alive.
klugesmith, It's a different Lego guy, but I've got the old 4hv avatar saved away as well. The Lego guy in my avatar is on the far right in this image, whereas the old avatar is the one in the center. (http://uzzors2k.com/projectfiles/coolidgexray/radiograms/50kev_legofigures_xray.JPG)

A fresh re-post of the legendary universal driver 2.1b is now online and also with some old freewheeling controller schematic/code from 2013: https://kaizerpowerelectronics.dk/tesla-coils/universal-driver-2-1b/
