Is that a dedicated ground bar you have at your desk? Do you ground each of your instruments to it first? What do you use it for? Is that tied directory to your house ground or to your water pipes? Just curious. I have the same isobars too :D Thanks.

Old broadcast Eng habit mostly, low RF impedance earth ground.  I have a pair of 8' ground rods below my work bench, the copper bar is tied to the rods via 2" strap.  When doing some low level volt-nut stuff I found it helpful to lesson some stray noise.

Yes, while in some cases it will act as an aggregator for common-mode noise. It's all about trade-offs, and having options.  ;)

But it damn sure is a pretty piece of copper-wrangling.  :-+

Probably not unless you want to build your own NAS. I'm thinking of potentially building my own, exactly to the specs I want.

Meh. Cheap WiFi router with whatever USB3.x/3.5in external drive WD is flogging at the moment. I picked up a 6TB Passport for $89 this Christmas. Sure, not a substitute for a server; but then, most of the desktop NAS aren't either. I just use it for video and backup storage anyways.  :-//

Since you can get rather huge capacity 2.5" portable drives now for reasonable prices, I prefer those because they take up less space and typically can be powered off bus, so I also reduce the number of wall warts I have to have plugged on. The latest one I got is 4 TB.

I have a couple of external HDD for backups and one also doubles as Media storage on the bedroom mini ITX. Part of the reason to look at the Synology is the Raid/automated nature of the backup with then occasional dumps to the external HDD. Also nice you can later on swap the drives out for larger ones fairly easily.

Forgive me Father for I have sinned
Darkness put her painted claws in me again...

Hi, I'm Nomad and I buy tools and electronics for almost 6 years. I'm quite new to pack, but I think I had a TEA syndrome since I was 14yo. Thanks to grandpa who did teach me how to use a hammer and screwdriver I got into quality tools and tinkering. Since I moved a lot and started to earn good money, my collection grew. Lindstrom, Wera, Erem, Mitutoyo, you know, the good ones.

Then I started to work in R&D and it got worse. But seriously, a lot worse, I think I overdid it this time  :scared: As picture is worth thousand words, please see attached.

Fortunately, my Miss does not find it wrong. She is supportive and loving. And I am looking for AFG right now on EBay, because I just bought two HP 3478A and I don't have AFG.

Regards lads!

Welcome, No.Mad. You'll be happy here. ;D
I TEA.

Welcome! We don't forgive here. We are fellow sinners. And proud of it. We love to see new faces and new stuff. So keep buying and come back often.  :-+ :-DD

Ah, more fresh meat to add to the grinder to further our justification of this insidious and forsaken lust for electron pumping machines.  >:D

BTW, welcome.   :-+

I mentioned before that the wife had bought me a new 24" VIZIO Smart TV for my bench.  All  I wanted was a monitor for the microscope camera but it is far more.    Cranked up the Amazon credit card sucking machine and got an articulated arm for it. It fits perfect.  The arm platform for the soldering station fits right under it without interference.    Second picture shows it pulled forward but not nearly as far as it can go and it can turn to face me at full extension.
The workspace is getting better and better.

Can I spy with my little eye AmScope on a boom stand with bearings fitted?

Nice setup you have here sire :D

It's no use fighting the removal of homegroups. Either keep hitting your head or deal with the new reality. Be sure to check out power consumption. That's typically a large part of the TCO for always on systems.

The Hood is getting ATT Fiber. They are punching through underground with their air-powered hammer and pulling the conduit. The access point to be buried is the size of a small doghouse.  :phew:

We actually have a fiber run 5m from the front of the house and are supposed to get access to it this month. Generally Oz is getting fiber to a node point then copper but we got luckier than most. Still a bastardised system thanks to the muppets in power  :horse:

I recommend building your own NAS on FreeNAS  https://freenas.org/.  If power consumption is a concern, consider SSD's for the storage array.

Just built a pair of 140TB systems for work, still migrating off all the old Buffalo NAS's my predecessors implemented.  ZFS file system is really nice, the Snapshot and Snapshot replication to the second system is fantastic.  Just recovered data for a department they thought they had lost due to a disgruntled former employee.  They only THINK they are deleting the data.

Local villages are in the process of getting FTTP installed using overhead fibre on poles. Lots of splice chambers, plastic widgets to coil excess cable without inducing microbending, and connectorised distribution points appearing overhead. The CDPs are made by Corning and use their 'Opti-Tip' weatherproof connectors. Our village has cabling in ducts, though, so I don't expect to see anything better than FTTC here. There were plans to install a new 'fill-in' cabinet/DSLAM locally to me to reduce the copper length, but BT Openreach managed to screw up the planning application paperwork.

All this is to meet the March 2020 deadline for 'universal' 10Mb/s access...

They only just put fibre in here because the NIMBYs whined about the planning permission. Every other postcode around us has had it for over a year. Asshats.

Anyway today is a steamer for sure. Decided to have an hour out to check the K2 for frequency drift after calibration and my good Racal 9915 just made an awful smell and gave out. Looks like the transformer primary has gone open fuuuuuu bastard thing. Seriously considering just buying a new one. I've now got two dead Racals and a pretty shit DG1022Z.

   I mentioned before that the wife had bought me a new 24" VIZIO Smart TV for my bench.  All  I wanted was a monitor for the microscope camera but it is far more.    Cranked up the Amazon credit card sucking machine and got an articulated arm for it.

I'll recommend that you do (or research online) a color rendering/color gamut test on your new acquisition while you can still return it. TVs usually make poor monitors as they are designed around a limited color reproduction range. The panels are actually different, as are the driving electronics and software. Documents and all-digital video (like that from your microscope camera) will tend to be pretty potato-looking, with poor contrast and color over/under-saturation and artifacts like ghosting/haloing of bright objects.

There's a reason gaming monitors cost so much more, and it isn't JUST marketing; it's different technology.   :o

The defects can be pretty subtle; that's why I'm recommending you research this NOW and be very critical of it while the no-quibble return window is still open, and before you get too attached. Displays sold as being "good for everything" are usually crap-to-barely-passable at any single task.  ;)

   Ever have a problem keeping your wood stiff  ;) Friday Night - Time to go drink Beer and eat food at the Pub :popcorn:

Aww, man... so close, and then the last accordion section broke.  :'(
Will you be able to epoxy it back together inconspicuously, or will you have to make another 2nd panel? Other than this painful example of the usual CNC/laser pitfalls though, pretty effing nifty.  :-+   :bull shit:*

Yeah, as opposed to here where we get "unlimited 100Mb/s" service that's really 5Mb up and damifino down depending on the carrier's mood.  :palm:

* Okay... I think maybe it's time to get rid of this effing Redragon Mouse and shitpost it on Amazon. It has something wrong with the driver where it will randomly highlight something NOT in the current dialog box and bring it into whatever you're currently typing, as it just did above, now highlighted in red. I thought it was probably just my ancient upgrade-over-upgrade build of Windoze, but it persists even with the brand-new fresh install on my SSD.  :-\

   My personal confuser is enough of a PITA already, without my mouse literally injecting BULLSHIT into what I'm writing.
