opening bids I didn't think would win 

so unlucky for some, I guess

my first switcher - a Sorensen XHR33-33 (no digital programming interface included) - not overly sure the 0 - 33V and 0 - 33A massively complements my linear Kikusuis but we will see.

Bonjour a tous!

Alors,  aux les Vide greniers - Cours de Vincennes a  Paris

discoverd  two gems   among  200 stands  2 km long street sale 

1/ Greenlee /Tempo /Progressive 200EP-G Communications telephone Tone Probe kit
with 77HP-G Tone Generator and linemans belt pouch
EU 5 like new! 
Added to my vintage telephone linemans kit....

2/ Bialetti Italian "Dama" stovetop espresso pot 3 cups was EU3 a bit used but easily cleaned and immediately deployed ......

Enjoying my Moka espresso while  probing telephone wires....(:-:)

HAVE AN ABSOLUTELY FANTASTIC DAY!

I have spent the last decade in denial that USB-C was really a thing but my recent delve into more recent SBC's and a couple of newer PC's said it was about time I got on board with this 'modern' stuff Don't get me started on what I think of the farcical PD spec using them ........

This is sort of NCTNICO's fault I ordered the FNIRSI 58  My now 5 year old 3A logger was out of legs for the job from when USB capped out at around 2A. For some dumb reason they went with USB-A pass through in this 'modern world' So added a few sets of adapters https://www.aliexpress.com/item/1005005033314417.html

Also gave me a reason to pull out my now 5 year old baby load (35W, 25V, 4.5A) to test the new toy with. On special if anyone is in the market currently for a baby load but for a simple bench one or throw it is a gear bag well worth the few $ https://www.aliexpress.com/item/32677950277.html

I bought a new video card for computer and processor. Also I also ordered written work for my dissertation at the university. I have no time to write it

A DSLogic U3Pro16 with shielded fly wires.

[DiTBho]

Two sonnet ppc7447@2.0Ghz modules liquid cooled for my G4 PowerMac!!!

Developing Gentoo/ppc32be for GNU/linux Keeps getting better and faster on this Mac.

2.0Ghz is really the fastest option. Common kits are 1.8Ghz, air cooled.

A DSLogic U3Pro16 with shielded fly wires.

I have a DSLogic Plus, but the specs of the newer U3Pro16 look like a big upgrade. Now I want one!

[DiTBho]

I am tempted to buy qty=2, DSLogic U3Pro32

32 bit data
24 bit addr
8 bit Ctrl and misc

For my mips '90s eval board@50Mhz, the DSLigic Pro specs look perfect, just it will cost about 600 euro

[DiTBho]

What about the software side?
I need to develop something myself in order to decode the datastream on the cpu bus

I haven't looked at the Pro versions in details yet, but for the other DSLogic products, the software is open-source: https://github.com/DreamSourceLab/DSView/tree/master
and based on libsigrok, so you should be able to modify it to your needs if it doesn't support a particular feature. Now we'll have to check whether DSView supports their Pro versions or not, but I doubt they would have developed closed-source software while the core of their products are using open-source software. So, should be pretty flexible.

i got a bt301c tdr tester for £ 27 and a camedia c-350 zoom for £7.50 both working well,more junk to keep lol.

I am comparing a secondo original MDD 2x7450@1.42 ghz with the 2x7450@2.00Ghz
The speed-up is impressive! Gcc is 1.6x faster!!!

UT622E LCR Meter

Why?
- Deep check on all those salvaged components.
- My Keysight 34465A (specified up to 100 uF by the way) takes ages measuring capacitors over 220 uF. I.e. useless above around 220 uF. This is the only booooo I have with this instrument I am using for 8 years now.
- I love test equipment.
- Make a definition file for test controller. You will have to wait a few months for this.
- Make a definition file for Profilab, if I ever get around making one.

What I dont like about the UT622E so far:
- UNI-T Device Manager software requires a COM port below 10.
- Black GUI (but that's only me).
- 100 MegOhms max. Sometimes I need around 1 GigOhm.
For capacitor microphone input amps.


What's the point of having a selectable test voltage of 0.1 V or 0.3 V or 1.0 V?

I don't think you're going to find a handheld LCR meter that can measure in the GOhm range. Pretty much every single LCR or impedance analyzer out there maxes out at 1-200 MOhm impedance. There are impedance analyzers out there that can measure up to 1 POhm, but they have a price tag that makes maxed out Keysight ones look like a budget option (also, those only go to 40 MOhm). I have them at work for material science (characterisation of insulators, they might very well be in the GOhm region).

Check out my latest green hoarding thrifting beauty: AKAI CS-F21 cassette deck in full early '80s glory. 11$
Oh god I love this thing.  Metal extrusion front panel, great three-position mode switches, heads look great,  I love the polished contour around the REC LEVEL knob.
Dolby B and C, manual type selector. I guess the auto sensing stuff came later on. And it's super clean, no funky smell.
I don't know if it works, I like it more as a sculpture.
I gotta go back and find the remote. As if!

[SiliconWizard]

Also I also ordered written work for my dissertation at the university. I have no time to write it

I'll assume this was just some trolling.

[Alex Eisenhut]

I couldn't resist opening up this deck, clearly it was well-cared for. The belts are fine, and the mechanism has a serious metal flywheel in there, I like it. No Tanashin here I guess.
There's a small envelope taped to the chassis with a hand-written note in French that states "belts replaced May 16th '97", with the old belts in the envelope. 
I like this PCB, it exudes serenity.

I remember from back in my near-audiophile days that Akai made some very well regarded equipment, particularly tape decks.

Here is the Keithley 617 measuring 1POhm on my bench  . It can measure up to 20 POhm IIRC.

Impedance, not resistance. 1 GOhm DC resistance is relatively easy to accomplish, measuring that sort of impedance in the kHz range takes a bit more effort.

At kHz it is really pushing it. 1POhm is 1fA at 1V or ~6000 electrons per second. At 100V and, say, 6kHz it is only 100 electrons per each period of the excitation frequency. At the same time you need to avoid a direct capacitive coupling as much as possible. Hmm, sounds like fun  .

I bought a set of IC-testing needles.

After two years of waiting, with goods in pre-order, today the two Xilinx S7 FPGA modules with PRAM finally arrived!!!

You still have a drive for the project?
