Today a new attenuator arrived for my SA. Safety first

[paulca]

Got one of these.  And here ends my short phase of buying cheap multi-meters.

https://www.owontechnology.eu/product/1362517/owon-b41t-4-1-2-digit-digital-multimeter-with-bluetooth

I like it, nice size, feels nice, screen look gorgeous.  I haven't really tested it out that much.  I tested it's resistence at the lower end with a 0.1Ohm resistor and it wasn't exactly accurate registering between 120mOhm and 200mOhm.  The ESR meter says the resistor is 96.4 mOhm.

I like the 5th digit, even if it's not totally accurate enough, but for working with slowly moving voltages like battery charging, having the extra digit a bit like the seconds hand on a clock is nice just to look at.

You can disable the auto power off, but annoyingly, like so many DMMs it does not disable the back light timeout.  I think out of 5 meters I have bought only one of them has that feature, the Aneng 9000 the backlight stays on if you disable auto power off.

Another negative on "useability".  The backlight button doubles up with "HOLD".  If you press and hold the button to turn the backlight on, it also enables HOLD, which is easy to miss.  Has to be disabled with a short press after the long for backlight.

This weekend an HP204D audio oscillator will arrive at my doorstep.

I bought the Dorsal experimenterboards (from kectronix.com) in order to steer my flipper zero more to electronics.

Just received the Aneng MH-13 megohmmeter. Very decent device for reasonable money, listed at $57 at the time of purchase, but with all the discounts active at the time I paid only $55 total for the MH-13 and the Aneng A3008 pen-style multimeter that I decided to buy for the sole purpose of satisfying the irrational desire of getting yet another multimeter.

What an awesome toy a megohmmeter is!
This model can test at up to 2.5 kV and measure resistances of up to 200 GOhm. Now I can easily blow up trashy multimeters and create beautiful blue sparks across narrow gaps between two conductors!

For the slightly more practical application, I can now do proper testing of e.g. flux conductivity and dielectric strength of PCBs. For example, I found out that a typical Chinese Green Double-Sided 2.54mm Protoboard™, when tested unused out of the box, withstands 1kV, starts to conduct an occasional spark at 2 kV and allows a sustained spark discharge at 2.5 kV between two adjacent pads.

One downside is that it is powered from eight AA batteries. I would much prefer a built-in Lithium battery. But there is sufficient room in the battery compartment to fit 3 x 14500 or flat Li-Ion cells, should I really want to do that. Will see how quickly it drains the AAs first.

Arrived today:

Ersa Icon-1 in mint condition for small money..
Now several tips are on their way.

Pretty sure I've measured seriously high temperatures in external cases when doing backups, hence my preference for one with a fan. Maybe I'll join your thread and run off some new measurements

I would avoid multibay enclosures.  I have a 5 bay.  I replaced the 120mm fan in it's base with a Noctua silent fan.  I am now going to buy single bays for all but the two raid backup drives.  Why?  The controllers in those multi-bay units try and do their own power saving by spinning down all the drives.

Are we talking the same thing? My comment, on temperatures with externals, was about M.2 SSDs but yours seem to be thinking rotating disks.

Having said that, I wonder if such external multi-drive cases would be available for the SSDs (other than the two-drive ones). It would be very compact in comparison.

Campagnolo Zonda 90s wheels for my road bicycle

Campagnolo Zonda 90s wheels for my road bicycle 

Your front wheel is likely worth more than I paid for my Merida Roady 

Today is finally the day to get rid of my HP I3 Clunker workstation. Jonsbo MATX case was a great price and stil plenty of room for a GPU and a couple of extra cards I need to fit in it as well.

@beanflying
A NOS Campy Zonda wheels 8speed (90s old new stock) set ~ 450 euro
A NOS Campy Shamal wheels 8speed (90s old new stock) set ~ 1000 euro

my Zonda wheels are secondhand, paid 120 UKP, not too bad 

I don't like carbon forks, only steel forks on a 90s titanium frame, but I needed something more comfortable than my old Mavic X wheels (very cheap, paid ~60 UKP secondhand) for longer bike rides.

Now I'm thinking of disassembling the Campagnolo Zonda wheel and mounting the Zonda rims on Mavic hubs.
Kind of hybrid Campy Zonda-Mavic wheels.

The trip to memory lane was extensive but not expensive. Got several slide rules/nomographs (including a long wanted Fiber Castel duplex with double logarithmic scales and a scale to multiply sine directly). Two HP Voyagers (one with badly leaked batteries) and a Mitutoyo micrometre. All for < Eu 100,--

[RAPo]

Also, this weekend anHP204D arrived, and a Philps Pm2525 joined the collection

[RAPo]

And a set of piping standardgraphs were added to the box.

120GB Kingston SSD for another PC build after both of the old 60GB OCZ SSD's I had didn't wanna function with a W10 install. 
Some 30NZD was cheaper than pissing around with them!

PPE, new radio earmuffs and Hygiene kits for 2 quite old PELTOR earmuffs < now as good as new.
500ml can of ROCOL RTD < fantastic metalworking compound.
10 pk of 125x22mm 1mm cutoff discs.
230V 125mm Bosch grinder at a price it couldn't be left on the shelf.

And lunch, with good company !

Nintendo Switch OLED for the new Legend of Zelda game, worth it.

hope to do the same.
 the reviews for zelda tears of the kingdom are excellent for this one!
an improvement on Zelda Breath of the Wild, that is saying something.

And we should do the same one day in Dec Bryan, lunch that is.
Member c47 not far from you was keen for us all to get together...... a pub lunch ?

Sounds good, Rob.
Closer to the day, I will have to check if SWMBO is all good with it.
She is a bit immobile, so won't be able to come, & I am her "primary caregiver".

Don't get me wrong, she "has all her marbles" & physically can do quite a lot, but she needs assistance with some things.
She will almost certainly say "go for it", but I don't like to leave her in the lurch if she needs assistance.
What with her condition, then the Covid episode, we have both become a bit reclusive.
