This is correct. I have bought some disks from him before (also he is tomdotstar on EBay) and they come as ordinary used disks with a new label stuck on top. Supposedly each one is…

They do sell, I've bought from them before.

In the US, those are radio stations WWVB for clocks and watches, and WWV/WWVH for shortwave. One thing I think is interesting is that not only are the digital formats these carry s…

You actually can still call NIST and hear the signal broadcast from WWV[0], though that's probably different from the telephone time of day you're thinking of, which might have com…

If you want to see how an actual application of this works, I've yet to see a description better than in CuriousMarc's HP 5061A series: https://www.youtube.com/watch?v=eOti3kKWX-c

You mean everyone else would have the "wrong" time whereas your clock is still bang-on correct for you. So you have become a time traveler.

I've done this to myself too. I once had a thermal receipt printer I wasn't using, so I decided to point a webcam at it and put it on a webpage so anyone could print random crap to…

I think it would have been more likely to be some kind of mechanical analog computer full of gears and cams (which some planes and missiles did use for guidance). Probably needing …

I do some retro-computing every now and then and of these old drives that still work (about a 50% chance), when I format them assuming all sectors are good, they will inevitably re…

In many ways this project is more difficult than building a professional train simulator (I've worked on one). 1. Professional customers are willing to pay for (and usually have an…

I wonder if they aren't sticking the die to the end of their finger, then using the bamboo stick to poke it off and get it into final position. That's probably how I would attempt …

I occasionally do some microsoldering, and I'll reach for a wood toothpick when I need something that's absolutely non-magnetic, soft enough to not scratch things, does not conduct…

My cousin has one. But he also lives on 5 acres, which is also not average either. Apparently prices on them have gone way up. The one he has now would cost something like $6K toda…

Here's a real world* example: https://www.youtube.com/watch?v=AAbyUaLN2QA *youtuber

For an anecdote in a different direction, my father bought a Ford model T a few years ago. Now, "classic" cars of the 60's and 70's are still very popular among those who lived thr…

The shortwave WWV, not so much, except to check if your shortwave radio is working. Canada's shortwave CHU was shut down last month. The 60 kHz WWVB, yes. Plenty of cheap wall cloc…

I think the idea is that you can make a machine that goes on the rails and installs them automatically. So you don't need to haul a bunch of equipment on site, you just drive one s…

I have a small CNC mill and can carve out a board if I don't have time to wait for ordered boards. It's a pain to set up to get it to cut properly, the boards are either one sided …

One thing that annoys me about am/pm is that the clocks have a 12 at the top and not a 0. So it goes 11:59 am to 12:00 pm and not 11:59 am to 00:00 pm. Even as a kid I was confused…

Like a burned out brick building, a burned down planet is still there, but still also burned down. Of course it doesn't 'disappear'

The other home security camera companies already make cameras in a doorbell form factor. Point is to do what you want with the hardware you supposedly "own".
