Anybody looking for a HP 3456a ? someone is selling bundle of 3 units for 40$. Shipping is going to be expensive though since they weights a ton.

https://www.ebay.com/itm/HP-System-Multimeter-3456A-6-1-2-digit-Digital-Voltmeter-3-UNITS/254453626522
Tempting apart from the sheer size, also I already have fully functioning 6.5 digit meters that are smaller, but I was wavering until I saw the GSP shipping cost to the UK, an eye watering $276.48  :wtf: |O

Yeah, shipping to me is only $10 less.  :wtf:

WAF aside, I've already got too many MEBBs/MESBs/MEGBs floating around the house we just moved into even for my OWN liking. I'm surprised they lasted this long though...

Indeed. Signal integrity in your measurements is not really a problem when it comes to red/green repairs and signal tracing. I refer people to simpler times when your only debugging and alignment tool for radios was a signal generator and VTVM with a diode probe. In fact guess what my Elecraft k2 shipped with for alignment and debugging (the signal generator is built in): (Attachment Link)

The Velleman is fine for everything other than forward engineering at higher frequencies.
That's what I was thinking, feed in a 400Hz signal and use the scope to see how far it goes and it should even be able to pinpoint the precise part that has failed, look for distortion / clipping etc and even take the odd voltage measurement as I work my through the circuit. Modern meters look ugly without their protective bumpers don't they?

Sorry... 64 x 96 pixels (maybe less) is just too little waveform information to display; you will not be able to distinguish distortion or clipping from display artifact. It's like those 2.1 digits Bell & Howell nixie meters. An interesting curiosity, but really not fit for purpose.  :palm: You'll see what I mean.

Modern...? I think your "crusty old fart"-ness age is showing a little, buddy. :-DD

A bit more than tempting. For me at least, it's an essential. When the last edition of The Art of Electronics came out I was at the stage where I hadn't done any electronics for ages and felt the need of a bit of revision. So I essentially read the thing cover to cover. I kept on running across lots of bits like "For more details on <subject in hand> see Xchapter <whatever>." Every bloody time it was pointing to what I felt I needed to learn next, every bloody time. There were dozens of hints that exactly what I wanted to know was hidden away in those bloody X chapters. I've been waiting ages for the thing.

Ahhh... so there's a "light" & "dark" variety? I'll keep an eye out for "The Dark Side" of maple syrpple ; that's usually where I feel most comfortable anyways. :-DD I guess the "light" is marketed for all those "Wonder White Bread" conservatives in the area (there are just oodles... seriously  :palm:) who can't tolerate actual FLAVOR.  :P


Okay... so like lasagna then. The only decent lasagna I've ever had at a chain was Tony Roma's. Well... that requires me to be in a bit more of an adventurous spirit; something to set aside for the New Year, methinks. Now is definitely the time for "family traditional" food-wise.

*Poke'-time*

I personally find dark amber maple syrup cloyingly sweet.  Not a big fan of maple syrup to begin with but I do prefer the light amber.  Mrs GreyWoolfe always gives me grief as I prefer my pancakes with just butter.   Lasagna from a restaurant?  My dearly departed mother would rise up from her grave and smack me in the back of the head.  Lasagna (Mrs GreyWoolfe) and stuffed shells( me) are homemade only.  Along with proper 3 meat meatballs and my famous marinara sauce.  If rumor has truth and Mrs GreyWoolfe's oldest daughter and son in law gift us a Kitchenaide stand mixer for Christmas, I will get the pasta and meat grinder attachments and try my hand at making my own Italian hot sausage.

When I get tired of the cold (not there yet ;) ) I'm gonna Snowbird it to your house. Sweet italian sausage for me, though...  >:D

I grew up in the land of Clover, Wildflower, Buckwheat and, believe it or not, Blueberry blossom honey. There is no such thing as too sweet for the ol' dwagon's biscuits, baklava, & oatmeal. :-DD

Door's always open.  Just give a bit of warning so I can corral the canines so you can come in the door.  Bring SWMBO and the kiddies, we're used to cooking large.  Oh yeah, Tupperware also so you can take some leftovers. ;D

We'd get 12 pages of posts every night for a week (at least).

I pity those who only visit here every few days!!  It's bad enough as it is for those of us who check in daily.

I unboxed the HP DMM this evening. Had low expectations on this one as it was "parts, not working" on ebay and I paid $85 for it, including shipping. I was pleasantly surprised to hear the fan spin up when I plugged it in:

890466-0

All the switch buttons light up and a quick check of the two wire resistance and DC voltage (up to 10V, at least) look good. The outside is a little rough but the buttons and connectors are all in good shape and it even has three of the four original feet, including both front wire bails.  :-+

I have to set it aside until next week as I am heading out to help my folks for several days. I am looking forward to digging into the manual and figuring out if I can do a rough and ready calibration.

Another tough afternoons 'work' on my new Plunge saw track. Keeping on the straight and narrow with the assistance of Beer and Vitamin D. Only off by 0.5mm in 1400mm but chase it out for an easier life in use later. Suck it up Northerners too your Sun will come back eventually :-DD

There is a TEA component at the end of this with some new shelves  ;)

Jackpot. I don't usually buy component lots but I couldn't resist this one. Lots of nice parts in it for test gear. Got quite a few Kemet tants, lots of high K ceramics, polystyrene caps, NP0 ceramics, CDE silver micas all sorts! All unused!

Tempting:

https://www.amazon.com/Art-Electronics-x-Chapters/dp/1108499945

A bit more than tempting.

I sucessfully ended the temptation.
Preorder done.

I haven't pre-ordered yet, although I've been tempted to. Two reasons: (1) I'm loath to give Amazon any money if I can avoid it, not until the bastards start acting more like a decent corporate citizen in terms of treating their staff fairly, paying some taxes and little things like that, (2) I'd much rather the money went to propping up the single remaining local bookshop while they are still there to prop up. We used to have 6 bookshops within a short drive, two of them large, now we have one small single storefront bookshop.

I’ll wait for the second printing i think.

As for book shops, we basically have Waterstones and Bernard Black. So amazon it is.

It strikes me that the sheer mixture of accents would give it a unique flavour. There's thee and me, two Londoners who sound remarkably like each other (TEA passim), an Essex lad, a bunch of Germans, I suspect Mnem has a  New Yexican accent, more New Yorkers, a Jersey Boy, at least one British Northerner, a couple of Italians, and then there's all the antipodeans. The only word that we would all pronounce in the same way would be beer/bier.

It'd be like the UN without the simultaneous translation and the mutual seething loathing...
