Nice. I see you've got great taste in soldering stations.  Do you work with optical fiber stuff?

I don't get it

It is a bit vague.
I'm guessing it is because the big binocular microscope looks as if it is mounted on top of the solder station.

I think he means that near the foam pads you see what looks like a piece of leftover fiber glowing in the picture, and the combination of kimtech wipes, alcohol wipes, tweezers, foampads and a microscope is also typical when working with fibers...

Yet, another ECC DDR4 16GB x 2, as DRAM price crashed since last year, and recent covid pandemic affecting the market, local distributor is dumping the stock, make it more affordable now. 

I guess this is the right time to beef up my desktop Ryzen with ECC memory. 

Wait. ECC? don't the server guys wanna install more machines since everyone and their moms are on the internet.

Exactly. Thanks.

I need to add another 16GB to my Ryzen machine,  32GB was not enough while doing some heavy photogrammetry work. Where did you buy this from?  It's all the same price around here.

I picked one of those up a while a go. I never checked what it's performance at 1.5GHz is. It's waiting on my bench at the moment so that I can create a 3D printable housing for it.

I didn't pay for it but I did get it. Nice new seat.

Buying these, I considered both the Bodum and this Krups grinder. In the end, the Bodum looked better and from other reviews seemed to be more high quality.

If I had the spare cash I might jump on both.

As someone who takes their Coffee more than a little seriously  The little Burr Grinder would be the pick of them unless you are making Turkish style coffee and it won't grind fine enough for that. Also consider a small modern hand grinder if it is just for yourself Hario or Kyocera make really good ones.

New Fluke 867B from year 2002, made in Ireland. This is my second 867, I already have one used made in Holland.

Ohms are spot on like when delivered from factory. After first charge meter stayed on almost nine hours so battery is also fine.

Picked up a couple new to me items for the lab this week.  These replace my 2465 and 2430A.

I've had the KitchenAid burr grinder since about 2002 and still use it every day.  It's bullet proof and grinds perfectly.

Prismsound DScope III audio measurement set.

Been after one for ages, superb bit of kit for what it does (The AP has a slightly better generator, but the DScope software is IMHO much more usable).

All good things come to ebay if you wait long enough.

Prismsound DScope III audio measurement set.

Very nice, I've wanted one for ages but it is far too expensive for mere hobbyist use, so I had to settle with the old Japanese analysers instead (Panasonic and ShibaSoku). I only needed quick and dirty THD+N measurements so it's more than enough for me.

Curious as to what the typical generator/analyser performance is because the spec is -108dB THD+N and at that level, I think it's just running straight into an ADC instead of notching and processing, right? (like the higher end AP or the traditional analysers from Japan)

[dmills]

The generator is actually the weak point, +4dBu 1kHz is showing about -104dB THD+N and yea I think it just does the ADC thing, but it is also a faction of the cost of a fully tricked out APx552.
It needs to go off to Prism for cal and a tune up.

I mainly wanted the multi tone IMD stuff, usually more important then THD once you get to this sort of level.

I do wonder if the smart way to do a modern THD set is not to use a two channel DAC as the generator and sum one of the channels into the signal returned by the DUT, then the software can adjust that side of the generator to null the fundamental by some sort of LMS loop.
Some of the modern AKM parts spec that you can build 23 ENOB DACs and other such wonders, but we all know how tricky that sort of thing can be in reality.

Too fast...

[dmills]

Oh I am sure I can build a better THD setup, even a much better THD setup, but 100+dB down for audio, do I care?

I mean it is not like ANY loudspeaker is going to manage that at significant power (-60 is a stretch for most of 'em), and transducers are the only really interesting bit of audio these days.

I'm pretty sure that the Audiofools will see that differently. First you need to make sure that your IEC plugs are gold plated, then you need to balance the cable on teak wood bridges so that they don't just lie on the floor. Then comes the copper that needs to have been extruded in the correct direction so that the electrons flow best and we haven't even started on the capacitors made from unicorn tears by naked virgins. Obviously none of this is measurable with the insufficient equipment that we "non-believers" use, but the "trained ear" will notice an obvious improvement in (add some non-defined unit of clarity, dynamic vibrance or whatever here).

Indeed, the room is the thing in the first instance, but you ever tried to tell someone that?
