Where can I buy a large analogue meter?

Still huge. Unencoded would be ridiculous.

Mine appear to be limited by the CPU speed, one core is all the program will allocate per camera, so I only get 15 fps max. Usually 7 fps as the computer is very busy running Boinc.

I got some cheap shit from China. It's never the resolution advertised, but that means they'll panic and give you 50% off the already low price.

No, we don't have to. We do because we can. :-P

It achieves nothing apart from making you like like egotistical idiots, you're the laughing stock of the world.

Wirewrap used to be the standard for GPO wiring blocks.

The company I worked for prior to my recent retirement made a wire-wrapped supercomputer in the 1980s. We sold one into China, and they took it apart and copied it. We started getting support requests for computers we'd never manufactured.

Which is why they went wrong so often. Yeah lets just hope two things touching with no solder or pressure just happen to conduct. It's the way kids make stuff. Twist the wires together and hope for the best.

Charge them for it and make money.

I'm guessing this "supercomputer" was about 1 MIP. My computers collectively do 30,000,000 MIPS, in my garage.

Oh I dunno, I did wirewrap a complete 19 inch rack with eurocards long ago, Had some RF too, well hundreds of kHz ..

This was also fun:

and this more recent:

or this from long ago:

peeseebees? not me.

That's what I have mostly done. It's not extremely busy but I like to snoop on what's coming and going from the local airport. There is no ship traffic in this state :) With global warming maybe we will have an ocean in a couple of centuries.

I've picked up a little SSB traffic but this area requires good antennas to pick up anything besides 2m.

I've still got the tools and an assortment of wirewrap sockets but haven't done a project in a long time. I got away from hardware when surface mount came in. Even with magnifiers I don't have the vision to deal with that anymore.

You assume there is a circuit board to solder anything to. Wirewrap is great for prototyping before you bother with a board. Of course there's the dead bug method.

Whoever did the dead bug arduino has a lot of time on his hands.

Then there was the hybrid where circuit boards slotted into sockets but there was no backplane so you wired it up point to point.

Those all look soldered. And that's the way I like to do stuff.

I astonished someone at work when he was trying to read a surface mount resistor value through a magnifying glass. I glanced at it without one and told him the value. Apparently I have the eyesight and the hearing of a 16 year old. Unfortunately not the body.

That's not a general problem. There was a period with the early Athlons that didn't implement some of the new Intel instructions but I've leaned towards AMD with no problem.

It wasn't AMD but I recall one processor that ran CP/M and DOS, both rather poorly. National maybe?

I still see solder. I've made stuff without a board, but I always use solder or things fall off.

It's a f****ng problem here. I run the Boinc projects Cosmology and LHC that use Oracle Virtualbox to run Linux under Windows. It slows the interface to a crawl. The same doesn't happen with Intel.

4 security cams go into one of those 4 channel security recorders from China Works very well, it does not record anything, I take the output via the LAN and re-encode it with ffmpeg, The intersting things is that one Raspberry Pi 4 with 4 GB memory records those 4 cams, plus 2 other IP cameras plus 2 audio tracks and the procesor load is still very low, plays background mp3 music without hickups at the same time! and I can browse the web with chromium at the same time. Raspi is a quad core.

I use .ts format as it is more flexible and easier to fast-forward and go back in. bp1.ts is just airtraffic, weather air pressure etc from server on an other raspi. other audio goes to the audio directory.

Nope, vast numbers of DEC minis were done that way.
