For no good reason I stumbled out of bed a few minutes early this morning. Went to kitchen to get coffee, glanced out the back, then rushed to get my camera.

Sometimes it is worth getting up.

Let me guess, you live near Bristol
OK, I'll ask the question, that everyone else is scared of asking, why does living near to Bristol or Brizzle :-//

When I google for Bristol, I'm getting a nice picture of one of the inhabitants there.   :-DD

I wouldn't call my ex famous :)

Question for all of you. What common object, other than a ruler, would one use for scale in a photograph that is universal? Yeah, a ruler works but it doesn't have that same visceral feel that, say, a box of matches does.

For the Brits, a standard box of matches would work, but the "standard box of matches" varies in size around the world. A packet of Gitanes is the same size the world over but most people don't have a pack of French Cancer Sticks to hand. A bunch of keys? Pretty universal but you don't really want to embed the key profile of your front door key in a photo for publication. I've been over a few other things in my mind and discounted all of them as not universal enough. Pencil? The ubiquitous Bic? Too long and thin. Cups and cutlery are too variable in size.

I finally hit on a standard pack of playing cards. Right kind of scale, the same size all over the world, something that fits in the hand.

So, can anyone else think of a common household object that is truly universal worldwide, and that fits the bill better than a pack of cards? Thoughts? Something obvious that I've missed?

I like to use a AA leak-tube.

It's the transformation that happens after you marry them. Been divorced from the mother of my children since 1995. She turned into a ugly, fat, angry, and frustrated old sow. To this day we cannot have a decent conversation without it turning into an argument within 5 minutes. Think "Angry Karen" 3x. In fact, just by coincidence her first name IS Karen.  :palm:

A few years ago, I would have agreed. But now she has managed to partially estrange herself from her daughter and sisters by becoming a rabid brexiteer.

She chose to make problems after we had been a couple for several years and 3 months after the marriage, and then after my daughter was born. Only the last can be attributed to mild undiagnosed post-natal depression. She refused to acknowledge that possibility, so no improvement was possible.

For my daughter's sake, I defended my ex for over a decade. Now she has again chosen to create problems, this time w.r.t. being a brexiteer. My daughter is old enough to understand her now, so I no longer actively defend her.

Don't know what is worst:

1) Stickers
2) Permanet Marker
3) Nicotine layer
4) White plastic going yellowish
5) Scratches on display

First check is always is something is rattling inside, then I open the puppy up.

Ohh I need to buy something now...

Ok 3478A test report:

1. RIFAs are good. No sign of cracking. Will replace anyway.
2. Main filter cap tests good for ESR.
3. Battery backup at 3.044V. Need to work out if that's ok to leave or not.
4. Self test passes.
5. DC volts -> works fine. Agrees to the mV with the 8060A
6. AC volts -> works fine. Agrees to the mV with the 8060A.
7. DC amps -> works fine. Agrees to the mA with the 8060A.
8. Resistance -> works fine. Agress to the ohm with the 8060A.
9. All keyboard buttons work.
10. Front and rear jacks work fine as does the switch.
11. AC amps untested. I'll do that another day but I don't need it really.

That's a win!

I want one. No, I won't trade my 427A for it.

Further, since there's a DER EE DE-5000 on top of my birthday wishlist, I'll sit in the boat for a few weeks.

This, because what I'm really lusting after is a 4W resistance measurement and better capacitance
capabilities.  I think the DE-5000 will give me that, with inductance thrown in for good measure.
A 3478A is just b'cause ahh wants it. A perfectly good reason, indeed.

Just bought a 5316A as well. I noticed it had the channel C 1.3GHz option installed. They usually ship with an OCXO when one of them is in. Worth a gamble. Same seller as the 3478A  :scared:.

Need a totalising counter for something as well.

Confusion, no - but I haven't claimed that.

"Context is preserved" always makes me think of leopards, as in https://www.goodreads.com/quotes/40705-but-the-plans-were-on-display-on-display-i-eventually

There is, of course, good taste involved in the decision as to how much to snip and how much to preserve. Too often I've seen people snipping so much it makes life more difficult for a reader, or worse.
I suppose some of us find minor tasks more challenging than others.

3) Nicotine layer
4) White plastic going yellowish
5) Scratches on display

I vote #3) Nicotine layer

When it's thick enough, it becomes somewhat conductive and wreaks all sorts of havoc.
The others are usually mostly just cosmetic, even at their worst and I generally tend to prefer functionality over cosmetics in most cases.

Not that it's a poll, of course...  and they're all annoying...  :)
