One more thing lost in transit that arrived today:
- LEMO Connector FGG/PFG pair. Obviously is not the original LEMO branded one, since for the use I'm gonna give to them it's hard to justify the retail prices of them.
I bought one year of 1Password subscription today. Well I got scared by an InfoSec ghost story from a classmate of mine, and decided to immediately fortify my online prescence.
I don't stop ... Another meter for the collection. 1K2 resistor measurement
Another meter for the collection.
Are these old devices with TH components assembled manually? I mean component placement and soldering. Did they use any assisting tools or techniques? Like, component leads can be shaped and cut in advance.
I picked up an LPKF ProtoFlow S for $500 at auction. Hope it works better than my Puhui T962!

Oooh... I have a deep love for Philips T&M equipment. I have a PM3214 scope sitting within arm's reach as I type this. I'm its original owner and it'll probably be buried with me. Your meter looks of the same vintage, they'd look like a family sitting next to each other.
https://www.aliexpress.com/item/32982282829.htmlI unpacked this thing today..I'm happy as a... uhm.. happy thing.. Works great! Can tell it's 30 times better than the heated 30w solderpump/plunger thingy I've been using..
I have a second gun for it on it's way, It comes with some spare parts, I plan on having a different tip on it, so I can easily hot swap between two sizes. I do suspect getting the vacuum line on/off will be tiresome in the long haul..
Scored a cheep bench grinder. I have been looking occasionally and this was on the local Craigslist-Valley BG-6 6", 3/4 HP. Fairly quiet on power up and very quiet on power down, no bearing noise that I could hear. It was listed for 6 days when I saw it and figured it was probably gone but I would take a chance. Just picked it up for the princely sum of $20 USD. They sell online for twice that new but only come with a 1/2 HP motor. Now to find a cheep bench drill press.

Picked used RTX 2060 Super from Amazon to play with Machine Learning. Expecting to see 2 orders of magnitude performance improvement over otherwise nice K620, when utilizing tensor cores with mixed-precision models...

You bought the wrong card. There are two different cores for the RTX 2060: the original RTX 2060 based on TU106, and a newer version based on TU104 that failed to qualify as RTX 2070. While nVidia did turn off features on those failed TU104 to align with TU106 in terms of game feature, a lot of non-game features are left on for whatever reason. Those RTX 2060 TU104 cards can perform close to an RTX 2080 levels when coming to non-gaming tasks like non-real-time rendering, compute and ML.

Yeah, I bought the wrong card. I was looking for Tesla V100S, but strangely I can’t find one in a budget of few hundred dollars.
As for the RTX 2060 Super - it is definitely better for ML than its non-Super siblings both the new (TU104-based) and the old (TU106-based) ones. Significant differences: 2060S has more memory (can train in larger batches), wider memory bus, larger L2 cache. Marginal differences: slightly faster performance (in TFLOPS) due to 2060S having somewhat larger number of CUDA cores and tensor cores that run at slightly faster clock.

Nice buy.
Some of these older motors are easy to repair and have standard bearings. In my experience buying older shop equipment (grinder, lathe, drill press, bandsaws, etc..) is once properly repaired is they will outlast the cheap/regular stuff.
Looking at what seems to be embedded metal on the wheels I would invest in a dressing tool and check balance properly before putting it to use. Also a good pair of safety glasses or a full face shield of course.

Benchmarks says otherwise if folks at Gamer Nexus are to be trusted. They have benchmarked the 2060 TU104 against both 2060 Super and 2080, finding the 2060 TU104 leaning very close to 2080 when running their suite of non-gaming tests. The key here is that other than spec sheet, there are more design differences in the TU104 and TU106 cores, some of them that is not reflected in the spec sheets, yet so fundamental that nVidia can not turn those off when binning the chips down. Something like improved FP64 handling, a better tensor core/RT core design, even physically spreading the cores out more so heat transfer can work better.
How does AMD bode now with ML? There are folks now buying retired mining rigs loaded with RX 470 and RX 480 for ML tasks.
Lesseee,
Two staplers, A Swedish Isaberg Rapid and an USA-made N-C J60.
5 pairs of scissors, mostly for fabric. Swedish, Finnish, and UK made.
3 wood chisels, 2 Bacho / E A Berg and one Finnish, Sorsakoski.
3 sheet metal shears, US / German made.
BSPT 1/2" thread die, for normal die holder.
UNC 1/2" die and taps set. I have BSW but lacked UNC in 1/2".
I'm holding my breath a bit for a quite fascinating piece of TE to top this off.

I am actually planning on replacing the wheels with a wire wheel and polishing wheel for what I want to use it for. I will see about picking up a dressing tool and I do have a full face shield already.
Edited the autocorrect booboo in the original post GreyWoolfe.
Dressing tool comment was if you intended to use the originals as shown in the picture.
Best of luck with it.
Cheers and stay safe.
Shallow Rake Aluminium blade for my Tracksaw, V slot and general Aluminium/Acrylic choppage. The other is just a prop
A nice accessory for my scope and DMM, sort of the opposite of the uCurrent. Does that make it a MacroCurrent?

No it's uCurrent on steroids
So I encountered an IKEA Tradfri Zigbee LED light bulb at 1/8 its original price in the as-is section of my local IKEA store today and snatched that. Now I have a known good Zigbee Light Link target, time to cook up that AT86RF231-based ZigBee module, either as a Pi HAT or a USB dongle. (The USB dongle option uses STM32F103 as the main MCU, and that version also allows me to throw in an additional PA/LNA/RF switch combo chip for added sensitivity.)

A TL886II+ programmer.
Nice feature:
It could test logic ICs also....
Kelvin leads for the Fluke 8505A. I had to cut the nanny shields off the plugs so they would fit in the non-CAT banana jacks.
