Ordered a 300mm × 100mm × 10mm block of 6063 aluminium.  Shipping and handling was three times the price of the material itself :-[.

Ouch!  That hurts...  Shipping is usually what makes me spend too much, especially if it will otherwise be more than the cost of what I need.  Figure "Might as well get some more things if I'm getting whacked for shipping" and proceed to load up.

No local metal suppliers? Its a normal extruded sheet right.

Bog-standard 300mm cut from a 6m long EN AW-6063 T6 100mm×10mm extrusion (about 12" of 4"×3/8"), yes.  No, I know of no local metal suppliers in or near Helsinki, that would bother to sell such offcuts to hobbyists like me.  Hafta order from Oulu..  but all told, it was under 20€ (about 21 USD) total, so I'm not complaining too much.

New in box dirt cheap in the local market: an Amprobe AM530. Never had a meter from this reputable brand.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Absolutely.
More than three quarters of my equipment and tool purchases over the last 12 months can be blamed attributed to this thread.

Not directly electronic, but...

A 3/8in drive digital torque-angle wrench with a range of 5-100 ft-lbs. Does tracking, peak hold, 10 memories, presets for torque and/or angles, converts to all metric and imperial units, etc. We're doing a bunch of development using various kinds of motors to drive various kinds of loads and in some cases (particularly hydraulics), knowing the load's torque is extremely important. Everyone's existing torque wrenches went up to 250+ ft-lbs because they bought them for working on vehicles, but we're dealing with much smaller values and most torque wrenches aren't accurate in the bottom 20% of their range.

I personally already owned a very small, torsion bar style 1/4in drive torque wrench that reads in in-lbs but its range was too low. Also, difficult to read accurate values from their scale-and-needle "displays".

I've never before seen a torque wrench that also measures angles of rotation. Apparently some fasteners are tightened that way. You set them to a certain position or a certain torque, and then rotate them a prescribed number of degrees past that point. Very interesting.

I didn't realize I had hit the 10,000th post in this thread!

This thread, and Bad Obsession Motorsport for me.  I hope Nik would be proud: I needed this material for a bracket.  (I need the 10mm thickness for a 3mm grub screw.  No mill, you see.)

I am seriously hankering for a Proxxon MF 70 micro mill.  I could do so many brackets, heatsinks and custom enclosure modifications, and brackets for my Linux SBCs and microcontroller projects (Teensy 4.0 overclocking heatsink maybe?).  Only, getting one would run me dry (I'm broke), and then get me evicted due to noise, as I live in an apartment.  Eh, might have to risk it: I don't like my neighbors much anyway.

Not at all uncommon in modern mechanical equipment. Cylinder head bolts are often single use and the degrees of rotation beyond a specified torque is to apply the correct amount of bolt 'stretch' tension.

It's mostly due to aluminum being used more. I've never bothered buying one but I used a "manual" angle gauge with my 1/4", 3/8", 1/2" and 3/4" torque wrenches. Even the top of the line wrenches are cheap now. My 3/8" and 1/2" were about $1200 when I bought them, some of the first digital snap-on wrenches..

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
Don't tell my wife how much this fun costs ... I want to live to build.

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.

A K210 board, an OV2640 camera and an OV5640 auto focus camera, plus a TFT screen.

Not really for anything, just felt I need to jump on the band wagon of machine learning, and maybe publish some sarcastic works, like the controversial material science journal paper describing doping graphene with bird drops.

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.

I 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.
