Personally not a huge fan.

What Metcal you used and how?

That was the MX-PS5200. The heating performance was fine but it's mostly the available tips that I liked less than other brands, and I didn't think the price difference was justified.

German WWII "Mause" morse code key for clandestine spy transmitters, VERY rare.

Perfect condition, made in 1941.



Searched at Ham fleas in EU for years, finaaly , at a good price....

Have a great day,


Jon

..just arrived, super quickly, from FedEx / Probe Master:
 
.10:1 fixed probe (4905-1) 250MHz, 1.0 m, gold plated

..and to make up the order,

.lead forming tools (801, 802, 901 - 3 piece kit)

Also, the other day AI inspired purchase for banana jacks to barrel plug lead - for upcoming AlienTek HP20 hot plate - to be run off the Sorensen XHR 33-33 , hopefully.

I got my hands on the Shannon ST-42 tweezers to repair a PSU I was asked to repair. I hope it will help me in avoiding to desolder every cap to check if it's still good

For my understanding:why would the use of tweezers be any different in measuring components on a pcb?

I have those tweezers and often I need to insolider in order to measure correctly.

I bought this last Friday:

A logic analyzer from Fnirsi (my first Fnirsi):

As a rule, in automatic mode (F=1 kHz), you can check the capacitance and ESR of the capacitors you wish to test directly on the circuit board—naturally, after discharging them first.

I am not a software/computer expert....

Found Dumped  with huge  pile of parts on main shopping street in Paris, 6eme

What are these? Any idea the value?

Enjoy,

That MSC board looks like an SMARC compute module... can't read most of the chips, but the processor is an iMX8. Looks like they're ~$50-$200 USD for new ones, probably mostly driven by how much ram and flash it has on board.

Abeyer, many thanks, I found these links...

Amazingly they were NIB with static sealed bags, the gray rectangle in upper left is one of 16 HS silicone transfer pads.

Are these old version or current?

Have a great day,

..retrieved from the blue (paper) bin yesterday - thanks Evri 

Tested this morning, de-stressed - my first hot plate - AlienTek HP20.

Ran well on the Sorensen SMPS

Tested out on a mouse switch - Parturient montes, nascetur ridiculus mus

dislodging an 0201 resistor? too

I bought a set of banana to wire connectors with Wago-style levers.

If you are lucky all of them are crimped correctly internally and the jack wont wiggle around. I think I had one or two with loose internal crimp so not good for high current or low resistance measurements.
You can open up the case and solder the connection if needed.

Karel, I have one esp32 that came with my Elegoo Kit and two more "chinese clones" of the Esp32 I use together to study various communication protocols.

Would that nucleo be a good card as an "upgrade" vs an Esp32 to build projects ?

A successful auction — a complete Anritsu S818 kit in like-new condition. Even the battery still works and holds a charge for about an hour. The highlight of the lot is the 28N50-2 and 22N50 calibration kit.
The instrument turned out to be fully functional. A day later, I measured the calibration standard again, and it showed an absolute SWR of 1, unlike VNA for DIY.

Couple weeks ago, I dropped into the London (Ontario) Amateur Radio Hamfest.  I was debating with myself whether or not to go all the way there.  Stumbled across a TEK2715 Spect An. (9kHz - 1.8 GHz) on sale for CDN$350.  I bought it assuming it would need fixing.  When I got it home it powered up, went through all its checks and worked just fine in all modes with all controls.  I thought I did pretty well considering that in very good shape, these go for about US$1000 on ebay.

For the second time in a row...   a clatter of SOIC 74 series gates for a project.  Only for them to just be "too many" and for them all to be replaced with an FPGA.  While I collect a right old collections of SMD 74series in unopened bags.

[armandine2]

...a better Evri experience  today to the door.

The "new" must have TE perhaps - AlienTek DM40C 

..went for the better probes and a screen saver protector - which I've put on rather offset right, but it works for me (could've been much worse).

The meter does have a nice display.

Not really Test Equipment but this is something I wanted to have for a while and now just went for it.

[armandine2]

.. haha, just been programming my HP-71B, in between assembly of the just arrived crystal tester / frequency counter.

..a bit of a pain to put together - I went for two smd 47pf (C0G) caps either side of the crystal, not a good picture. Seems to have worked.

[edited to add counter measure frequency => 2.5 Vpp (50-ohm) and 5.0 Vpp (Hiz)]

I want to read (or maybe I don't!) the motion control logic for driving around with five stepper motor driven swivel casters.
