IIRC, WSCs were only superseded as the definition in 1990, by the Josephson Junction. They had a long reign. I'm pretty sure they were used in some form in early bench DMMs. They were. In my Solartron 1420 it is used, via a trimpot, to calibrate the internal voltage reference - a neon bulb. I presu...

OTOH my Land Rover's fuel gauge (scale: Roentgens/hour) came from this famous shop in Cambridge: https://www.cambridgeonline.co.uk/img/250px/6226.jpg I think I've been in that shop before myself, was it in Mills Road, along with the other shop I used to frequent, Cambridge Recycle I think it was ca...

We spoke about WSCs and volt nuttery briefly at FRARS last August. We did indeed :) Shame the Harwell ARS website only contains the ambiguous statement "the rally will not be taking place in Feb 23". WSCs were a thing I read about in a physics book when I was ten and I wanted one because ...

I have a idle ambition to own a Weston Standard Cell. The saturated ones are usually buggered. I do have one that isn't, as the calibrator inside a DVM. The unsaturated ones are OK provided they've not been upended/shocked. Good luck with shipping them legally and safely! They make good temperature...

No need to be blue with envy; all you have to do is write "blue with envy".

have seen that movie many times, but never heard that story. when backpacking up state we always joked around the campfire about coming across a banjo playing albino. sort of a let down to know that the slack-jawed backwoods yokels probably can't actually play the banjo. I only heard it a few weeks...

Ah. Doing more with less. Good hack. I love the hacker ethic, even if (or perhaps because) it does merge into hilbilly engineering sometimes. oh great.....thanks buddy......now every time i look at that sweeper "dueling banjos" will be going thru my head. I'll give you McGyuver if you pre...

Well some people would disagree with you about "That YIG goodness" - people who've had a YIG oscillator fail. have owned 8555a's, an 8569b, and various 8620 plug in modules with yigs and never had one go tits up. (maybe i am just lucky?) since i never got to work on one it motivated me to...

That is what mnementh said, all the built-in ones are still working, but support for others that are not built-in but are considered "standard" which used to work now no longer do. The built-in ones are somewhat restrictive in their selection and could do with being expanded. Nah. We've m...

Here's an advert; the two pots under the CRT are focus and intensity, both 5Mohm around 2kV : https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/?action=dlattach;attach=747636 Internal view. The two pots are bottom left. You can't see the PTFE cable running fr...

Your next assignment, should you choose to accept it, is to extract the Tek492 PSU for recapping.

The one after that is to replace the Tek1502's front panel brightness pot, which has 2kV across it, and can be operated in driving rain and stored under 300mm of water.

Bought something at the last Ramco auction. Not TE, a 19" rack mount radio receiver. Yet again poor packing by Ramco and poor handing by Parcel Force resulted in a bent side frame and bowed front panel. One thing sent to me by Ramco a few years ago (pre-covid) had a bent carrying handle for si...

Nothing wrong with making a big profit, I do that when I can :evil: But I at least wait until I've received the item and tested it before advertising it and I don't use other peoples photos (whiich may be illegal) True, but 12 times is bit on steep side, and of course, knowing Ramco, if they though...

I tell my daughter it is OK to make new mistakes.

Good to hear it's going in the right direction. And it doesn't surprise me about them using the wrong dressings - been there done that one 😩 Seconded. Wound care is a fairly specialised subject; ISTR seeing a couple of TV programmes about it. It doesn't surprise me that the practice nurse wasn't su...

No, not just a title. Also a scapegoat to sacrifice to any hungry regulators or wandering herds of self appointed do-gooders. 25 years ago and more innocent times. My view was that the company had been progressive, though sensible, since at least the early 60s. They could just have reaffirmed the c...

Typical day example is today: I hit a total of 1396 calories consumed and I'm full. Not a lot! That was some shreddies + skimmed milk + sugar this morning with a black coffee (no sugar!). Lunch was a gunpowder chickpea jalfrezi ready meal from Tesco and a chocolate mouse. Had some bread and jam for...

Here's one for anybody in "IT". Worryingly I'm not sure which of these job titles have ever existed. Perhaps we ought to start a poll to see how many could apply to BD, or mansaxel, or... Happiness Concierge Citizen Codeherd Stack Auditor Diffusion Architect Task Nomenclature Reimagineer F...

As for the benefits of small amounts of exercise... that is entirely wrong. As little as 20-30 minutes of real exercise... provided it is enough to actually make you break a sweat... done regularly 3-5 times a week will raise your basal metabolic rate considerably compared to a sedentary lifestyle....

So I don’t think I do too badly, but I’ll stop buying biscuits, then I can’t be tempted. My examples were merely intended to indicate how the details might lead to surprising ways in which you could reduce your calorie intake. Being an engineer, if it.can be measured then I'll measure it, and measu...

Yes, this saga I’m having has made me decide to seriously lose some weight and once I get the leg and ankle sorted, I’m going to do more walking and burn some of my lard off. Small steps to start with, like parking further away from the shop so I have to walk more. Then start taking short walks aro...

Oh bloody hell. Decided I'd catch up on the thread finally (been super busy) and got a face full of the other 80 year old stripper. I am now officially ruined :lol: Sympathy: zero. Relevant phrases include "architect of your own misfortune", "self immolation", "destroyer of...

Well, surely the District Nurses and indeed practise nurses are provided with suitable PPE gear FFS. The paramedics on Christmas Day never bothered with PPE but they were told I had Covid, bless them, they gave me the full mot and all was ok.👏 Most of the PPE is designed to reduce the chance of the...

If that’s supposed to cheer me up, nope it ain’t working, I’m going to have nightmares when I’m laying in bed trying to sleep through the pain of the untended ankle dressing and leg blisters. On the positive side, I should be testing negative for the Covid tomorrow, feel fine in that arena, smell, ...
