It's interesting. I think the "engineers mindset" is the same for most of us. Everything is a problem to solve and that's cool  :-+

The very cheapies seem to be more of a mixed bag over the LiPo/Acrylic KK Moon types. Mine turned up without any readings on the case and that seems to be far more common compared to when they first came out in that style like @Med got.

In most cases it saves me having to fire up any of the better Calibration gear and it just sits on the shelf for bench use which in truth is all I need in 95%+ of cases when teamed with the Agilent.

I agree, I've 4 x 5.5 digit bench meters, 2 x HP and 2 x Flukes, 1 x 5.5 digit handheld Brymen and 1 x 4.5 digit HP bench meter and oodles of 3.5 handhelds. The AD584-M sets up the 3.5 meters perfectly so all digits agree however when it comes to the others things are a little more interesting. I can get the 2 Flukes (8840A & 8842A to agree by leaving them for approx 30 minutes, the others I can get to within 1mV of each other which is still way within the design specification and calibration of 3 counts.

Today looks alright as I take in some caffeine but yesterday was a real bitch.........our main water pump broke, really broke.  :palm:
Castings smashed and gunna be a quite involved welding job that I really don't need right now.  :rant:
Much smaller backup pump installed.
Damn Murphy !
A little bit that and a little bit "I know I need 12" but all I can get is 10" on the SATA cables. Went to plug it into the MB, the other end broke.  |O So now i have some 18" cables in there until my 12" ones arrive and I can sleeve 'em up.

I remember in my youth, we had a jet pump in the barn freeze up; cracked right up the threading for the inlet nipple. After working the casting shut using a rosebud and the bench vise, I welded it up using 6013 rod on DC reverse. Had to do it about 3/8" at a time; weld a little, heat everything around the weld to relieve the stress, let it cool to "tsssst" hot and then weld another 3/8" or so. Got right up to the edge of the threads with my weld, then stitched back over itself for 1"; again, 3/8" at a time... but when it was done, I assembled with silicone RTV and it held water and drew up against a 22 foot head. For another 15 years.  :-+

Amazing what you'll do on a Sunday afternoon when you're faced with schlepping water for a barnfull of animals via 5 gallon buckets.

mnem
"That's what SHE said..." *Ba-Dump-BUMMP-TSSHHT!!!*
Well the busted pump was a locally made one a MacEwans H3 doing 1500gph and exactly why I won't use 5 gallon buckets.
Twas a mess, the pump head (reciprocating type) had busted off the gearing and was flogging back and forth along the pump house floor until it busted the piping and dumped 3000 gals from the full tank 300yds away into the pump house.  :palm:
Good thing the 3 phase supply and control 'trics and 'tronics are designed and engineered to cope with such an event.  ;)

A pic showing the busted off flange pieces on the floor and the (now rusted) breaks from where they used to be.
Got the cast rods needed to fix it and the welding experience required but will probably need to make a small furnace to preheat it.
Backup pump flogging way faithfully in the foreground.


Really, you leave mains cables hanging out like that, no strain relief or grommets tsk tsk :palm:

Nice little ebay score this week.



This is tangentially related to TEA because I'm missing things made out of wood. Lots of metal and plastic but there needs to be more wood. I am going to look out for some old panel meters, rip up the FET voltmeter I built a while ago and put it in a nicely varnished wooden box with black panel and chicken head knobs, just because!

Going for the steampunk look?

Old meters with lovely mahogany cases often appear in real auctions and hamfests, are bought cheaply, and appear on fleabay at entertaining prices.

Not steampunk. More natural materials.

Yeah, its like Hi-Fi gear, looks much better in a nice wooden case rather than a painted metal or plastic one.

Random rant here.

I've got a good tractor analogy here which is describes the last three months of my life. Company has a perfectly good tractor that does tractor things fine. Unfortunately the tractor mechanic left and a new tractor mechanic was hired. This tractor mechanic went to the local tractor trade fair and got loads of cool ideas about how a tractor should be. Thus the first thing he did was take the working tractor and stick things to it which are trendy. Then he repainted it. Suddenly it's useless as a tractor and looks like a donk car. Management are not happy about this and hire a massive tractor consultancy in to unfuck the whole mess. This company comes in and suggests the company just buy a new tractor, sensibly. Unfortuntely after much consultancy, a list of requirements are drawn up which are unrelated to the real world and the only possible way to solve these requirements is that they buy a lot of raw materials in and hire lots of their engineers to form these materials into a perfect tractor. After a year of meetings, the design for the wheels is complete and there is a mock up for the body and over £2m has been spent and there are lots of engineers sitting around playing Solitaire because HR were competent for once. At a financial review it turns out the company isn't doing well because they haven't done any tractoring for about 2 years and all their competitors are tractoring hard because they hire their tractors hourly from Amazon. So round three they hired Amazon in, but unfortunately due to the amount of accumulated shit, unlike their competitors, that they should have tractored off over the previous two years, Amazon's monthly bill is rather ridiculously expensive, moreso over a year than building the tractor from scratch.

Where do I sit in this nightmare? Well I've been carefully repainting the original tractor in its native yellow, removing the donk car features, fixing all the rust and holes and paying two people to shovel as much shit as possible.

I'm sure cthulhu was at that trade conference warping minds.

Edit: apologies for rant again.

Tractors are more reliable than servers.

Spending some spare moments checking out my 8656B.  Watched a video by our friend The Radio Shop and then popped the covers to enjoy my first personal encounter with some serious HP construction.

It's not something you can fully appreciate from videos and photographs.  Having something open in front of you makes all the difference.  Truly impressive.

Found this item on the bay of evil a few weeks ago - it was caked with about 100 years of gunk (not an exaggeration) but cleaned up pretty well.  I used to work for the company which made it, so it is a nice souvenir of a time when test gear could look like furniture and yet not be ugly.

Up to and including the point of actually having to do maths, yes. I, like many of us, will do "trial and error based on a educated guess" three times before I actually sit down and do the math. Twice. Or three times.  :-DD
