Re: Interesting findings on the internet

Indeed.

I rather like my Canon Powershot 16; small/light enough to carry around (unlike SLRs!), focusses down to 1cm(!) handy for TE/PCB closeups.

Re: Interesting findings on the internet

Most people are happy with their phone's speakers!

I played with a Kodak around 1999/2000, and found it ok for snapshots but not something I would take on holiday. Brownie rather than SLR.

Re: Interesting findings on the internet

My introduction (in Jan 1996) to digital photography was somewhat unusual since it was designed to illustrate (literally!) the characteristics of digital photography. It was a panoramic photo of the Golden Gate bridge approaches in San Francisco. By "unusual" I mean something I haven't see...

So I'm a jammy git with a immaculate, one previous owner, with manuals, RAM card and tracking generator 9kHz to 2.9 GHz spectrum analyser for under £100 and a bit of work. It is pleasing when that happens. I got an HP8562B at auction and Tek492AP via EEVBlog IIRC, for £350 each. Both worked from th...

Re: Interesting findings on the internet

I have only a passing interest in the shenanigans, mainly because shenanigans caused this place to be set up. It seems that the benta thread disappeared because benta asked for it to be removed, and the mods obliged. Best guess seems to be that benta was embarrassed by his thread, and wanted to to f...

Re: Interesting findings on the internet

Some AI data centres are rated at 1GW. Almost all of it will end up as heat. That's some serious cooling required. I haven't done the sums but I'll wager 1GW applied to the river Severn between Worcester and Gloucester, would raise the temperature to an alarming extent. Didcot power station, at bes...

I asked, "Why do data centres need water?" The response from various sources was that they use water for cooling. Not one of the responses used the phrases "specific heat capacity" or "latent heat of evaporation". It seems surface factoids beat genuine understanding. E...

I think the ear twitches.

Daughter's dog has to be sedated before visiting the vet, lest he uses his teeth to express his opinion of the proceedings. Allegedly the vet is coming to have a sneaking appreciationof the mutt, because he doesn't deceptively pretend to be frightened/annoyed/etc.

If you aren't excluded from the area, might it be a test of your equipments' out-of-band shielding and rejection?

Re: Interesting findings on the internet

W.r.t. the waveguide switch... You can just about see a horizontal line halfway up the waveguide holes. That's where the top half and bottom half meet. That makes milling out the waveguide conceptually trivial, but still requires considerable skill (especially, IIRC, with the tolerances). They were ...

Here's a simpler example made by Decca Radar, the first company I worked for. It is the brass rotor from a microwave waveguide switch used in places like GPO Madley Comms Centre ground station. This one is small; I remember some being maybe 30cm tall. I ought to polish it sometime, but you can make ...
