Re: Interesting findings on the internet

Here's a little quiz about valid / invalid email adresses: https://e-mail.wtf/ Lovely! I especially like the valid fork bomb and zaldo text addresses. Tried creating zaldo addresses on gmx and gmail. Gmx doesn't like the names, period. Gmail allows low complexity names such as "H̸i̵m̷ ", ...

R yes, because you can expect sufficient sig fig to be interesting.

L and C unlikely, because <0.5% seems to be "high accuracy".

Re: Hamfest inductors

Played around with it again last night.

Some 1µH inductors disguised as resistors with a silver band measured 1.1µH. Can't argue with that.

Some relatively chunky 0.75µH inductors measured around 1µH. Conceivably there is a frequency dependence of the core, but I'm unconvinced.

Hamfest inductors

A hamfest or two ago I picked up a couple of inductors because... do I need to spell it out?! Anyway, I like Muirhead and Cambridge Instruments kit. I checked for continuity but unsurprisingly my cheap component tested didn't bother to measure L. Hence I was dreaming up ways to measure the inductanc...

I always assumed it meant the same as it does in model aircraft - you've slammed the stick all the way to the stops and still pulling. :lol: That's why I grudgingly forced myself to learn to be a "pinch flyer". ;) Basically, yes, that's what it means. For beginners, however, it refers to ...

Re: Interesting findings on the internet

TD pulse generators were used for cable fault location, e.g. Tek 1502. Operates in driving rain, has a unique shorting BNC connector to discharge static on cables, used in Patriot missiles batteries.

My 1971 Philips 1.7GHz sampling scope has a 2GHz FET in the trigger circuits, BC107s elsewhere.

"Incremental" would be OK if the increment was in a realistic direction without caveats.

It depends on the person using the word I find. Pleasure from a closely related person's achievements is the textbook definition of pride.

She uses the dog as a remarkably effective Bozo filter. Those who can interact sensibly with that dog are likely to be levelheaded.

Cheese can be remarkably cheap, if you are prepared to compromise on quality :twisted: Even if not, there are worse vices!

Re: Interesting findings on the internet

Yummy :(

I find it helpful if people don't think I can clean up things.

Daughter's (nice pleasant) current lodger is a stroke nurse, with more than a little OCD. Daughter isn't complaining :)

I'm forbidden from asking her to see my house; she would probably have a fit.
