Test Equipment Anonymous

A lot of equipment used by the military runs on 115V, presumably USA influence. I doubt anybody at Ramco has powered it up, so I wouldn't be concerned. The PSU is a standard Boschert (sp?) SMPS, easily replaced. The 10811 has a separate PSU that is not turned off by the mains switch on the back pane...

There was more "justification" for the TF2700 than another 53310: small, light, and I hadn't got anything like it. And yet Telford rally beckons tomorrow. Maybe I'll have to resort to only taking £10. But that would probably be sufficient for several Tek 7000s; fortunately I loathe those! ...

[Let me know if you go after it. (I'm vaguely interested, and looking for a reason to not get another one). You've got one already. You can't afford it or could spend the money on something else. You haven't got the room for it. It would be a trip and hernia hazard. I'm weak; what more can I say. I...

Not necessary to find and select a strobe mode. All that's necessary is to sweep the focussed beam across the eyes. Even a "startle effect" would be significant, and possibly sufficient. ISTR being taught in school physics lessons that sparks were ~10kV/cm. Can't find that in my copy of Ne...

I'd quite like a better counter than my TTi PFM1300 handheld thing, but it's not something I use often and I don't really have room for 3U, even if is it shallow.

Looks useful for dealing with burglars, too. Indeed. You've even got the choice of either permanently blinding them, or braining them with it! Not to mention brainfreezing them with the strobe or giving them a Megavolt stunning shock, should you select one of the other ebay/Amazon offerings, more d...

So thanks for the link, Tom, much appreciated. Not that I'm scared of being burgled; I purchased 2 of them, as it is always handy to have a powerful torch around the house. The general-purpose string of "tungsten" LEDS built into the main body makes a pretty effective emergency light in t...

Yes, it will kick butt - and retina.

As I say, to reduce the chance of accidental indoor specular reflections, I loosely tape my torch in the wide angle position

Very low brightness is sufficient for a surprising number of purposes. Candlelight was sufficient for exam revision when I was a kid :( I do still have a large lump of paraffin wax somewhere, "just in case". I regard any description on Amazon as being deceptive, and use it as little as pos...

My presumption, without evidence, is messages stay in the outbox until the recipient has seen them (or maybe just logged in, or...)

I don't understand the vast variety of light-based units. Even Horowitz and Hill mention the multiplicity of similar units is "baffling". Fortunately professionally I've been able to stick to watts. 1970s amps also used to avoid attention given to "transient intermodulation distortion...

My brother recently pointed me in the direction of https://www.amazon.co.uk/gp/aw/d/B0FC5Z8GFQ "Relybo Torches Led Super Bright Rechargeable 1000000 Lumen Long Lasting 40H". At £8 including P&P, it was a "stupid price", i.e. stupid to spend more than 1s making a decision. So,...

Well, it is summer for another 23 days or so. At the risk of asking whether you know how to suck eggs, do you use "quick links>>unread posts" and (less usefully) "quick links>>new posts". Having said that, I ought to write up my playing around with my "frequency microscope&q...

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.

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.

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...

... never forget the traditional way way to insult a woman: call her a "professional" without further qualification.

iirc, that was also gnif.

It was halcyon., but it doesn't matter.

Editing the historical record is repugnant. (Reinterpreting history is fine)

Or the thread started by our very own bd139 https://www.eevblog.com/forum/news/foru ... msg5804353
Don't bother to read it, even though it contains a few good posts amongst the usual dross.

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...

Of curiosity interest only - strange things are happening at the Other Plaice. It appears it started with some odd, but to mind innocuous, moderator interaction with "benta" (7k posts). Benta eventually took umbrage and decided to announce he was logging out. Oh well, it happens. That ann...

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...
