Test Equipment Anonymous

Cossor had a distinguished history, being important in the development of CROs and radar. They made a fair amount of test equipment of various sorts. They came unstuck around 1960 over disputes concerning the Fylingdales early warning system and were bought by Raytheon, who were presumably interest...

They made some fairly ok ones later on into the early 1980s. Up to 100MHz dual trace delayed sweep.

Also I used to work for Cossor back in the day. Mostly full of people who hadn't got over themselves yet

Ah yeah been there.

That one was hell.

Quite possibly. I was presuming, possibly optimistically, that the equipment had started with decent cells. Even those could be compromised by a shite controller. Oh no it'll be shite cells and a shite controller. Is it possible to get anything else? I mean even the old SLA chargers were shite and ...

The possibility of shite controllers are one reason I don't like leaving low-end equipment containing Li batteries charge unattended. A wise move generally. I am less worried about the controllers than the cells themselves. The cells can look perfectly normal to a charge controller even if they are...

Further thoughts to ponder on: Scope ON = solid color LED and/or flashing if being charged. Scope OFF but charging = LED in a flashing state, changing to a different but solid color when fully charged. It's getting whatever the shite charge controller does out of the box :lol: The possibility of sh...

:D Pleased to have sown this seed....looking forward to your improvements. Yes a good idea that! Further thoughts to ponder on: Scope ON = solid color LED and/or flashing if being charged. Scope OFF but charging = LED in a flashing state, changing to a different but solid color when fully charged. ...

............. The intent with this is to "modernise" it. The original design is a 7.5V 4Ah (30Wh) supply which gives 3-4 hours of operation. We can do better than that now. So what I am probably going to do is the unthinkable and eviscerate the entire mains front end from it right up to t...

I must say it's not a thing that would have tempted me, but each to his own. I had a quick look at the manual and it said the batteries were necessary as they were used as giant capacitors. Finding replacement NiCds may not be easy these days. They were very tolerant of charging regimes and in part...

Yeah yeah yeah on it. Ok so the D32 arrived nicely packaged. It's a very compact little battery powered scope. 10MHz dual trace. Nothing fancy but incredibly useful as they are light, don't take up a lot of room and of course can be easily floated (consider SMPS). Also 100% fully discrete with no fa...

One segment was about somebody who had developed a heavily armoured vehicle. Amongst other things, it spat fire from near it's wheels, to deter carjackers.

That's cheap insurance! It wouldn't give me any worthwhile cover :( The Chinese are building railways under their belt and braces road initiative, which should reduce the artics. Don't know how the Russia invasion of Ukraine will affect that. It's not really. My travel insurance for me and the elde...

Roos and Emus are small beer. Cassowaries, numerous deadly snakes, Funnel Web spiders, gympie-gympie trees and that's just on land. In the water there are Salt Water crocodiles, Great White sharks, Box Jellyfish, Blue Ringed octopuses, sea snakes even more venomous than their land dwelling cousins,...

The only things I know about Azerbaijan are those baths that it was an early "oil capital", and that the modern architecture in Baku makes Donald Trump look restrained and tasteful. If I was young enough to go to silly places, I think it would be places in the Himalaya and one of the old ...

Presumably you are going to have a Naftalan oil bath for wellness (pun intended) reasons. Do the travel insurance companies say it is OK except for Nagorno-Karabakh and the Armenian border? I had to google the oil bath thing. Hell no :lol: I have specialist and rather expensive travel insurance tha...

Ok so all this thinking of Soviet stuff made me book another stupid holiday next year, because bugger all those normal places. So I'm off to Azerbaijan for a week or so. A small country wedged between Russia and Iran. This will involve flying past Ukraine, avoiding getting arrested and deported or ...

Final resting place

Ok so I was scrolling through eBay on the toilet this morning, like you do when you haven't eaten enough fibre for a couple of days, and guess what? I received a stupid low offer for a Telequipment D32. It's a very basic 10MHz dual trace scope which is by modern standards, not exactly that useful bu...

From what I know of the Soviet defence sector, the persistence of the things is because they had regulatory requirement to be able to be self-sufficient as a nation and they had a lot of stock left lying around. On top of that the cost was much lower than newer technology. There were also restricti...

I always regard rebranding as a negative. Either there is something to forget, or the managers know something isn't right but don't know what to do. That leads to "something must be done, this is something, this must be done". Always unwise to concentrate on either the wins or the losses....

As for stocks; timing is everything. Well knowing what you are doing is everything there. Timing is very different. Everything is easy in a bull or bear market. Timing is spotting the change from one to the other. Well it's more prediction and that involves research and modelling. Timing is the bit...

I wrote a few thousand lines of Pascal and later a few thousand lines of C. I only used goto a handful of times. Mostly it wasn't necessary. I was surprised the effect it had on some people - worse than heresy, like being uncovered as a devil worshipper. I thought the interview test was a strange o...
