Always wanted one but not for the crazy asking prices. Spotted one for € 35 and it's on my bench now  :-+



I own one of those!  I swear it!  I have photographic evidence of it being in my lab.  If only I could find it again.  Last time I saw it was approx. 2006.  But I have it!  It is probably wrapped in bubble-wrap and stuck inside a piece of gear...  Let me see...

I used to use one of those at work a lot, back in the day.
Nice device!

how they work? can it be used with fluke 187?

i know i can probably google it but as the discussion is going on here  :clap:  :-//

Well, I bought a Quad QSA30 pick and place machine from an auction in Austin, TX for $500.  Wow, I had no idea it would go so cheap.
Now, I have to arrange getting it packed and shipped to me. 

The guy who paid $3275 for the Samsung CP45FV that had been partially disassembled may have a very unpleasant surprise.

Most of the other P&P machines did not sell.

A license of VMWare Workstation Pro. Managing another computer is just too tedious, so I sold my Windows laptop and migrated all my remaining Windows apps to the VM.

And no, I'm tired of fighting VirtualBox's myriad of bugs.

Scored a 4275A for $5, with a spare parts unit and all the options. (Except the bias voltage control box, anyone got one to sell?)

I think I paid too much. :D

Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

VMWare is a great VM. I've been using it for the past 12 years and it got much better over the years. Only a handul things do jot work that well.

I've bought today one of the coolest counters ever.   :scared:   :-+

A Rohde & Schwarz FER BN4721    8)



The counting valves are Valvo E1T. Here is a description in German.

Pictures from the website:


This is a mp4 video from the website wellenkino.de from forum fellow Martin.M.
Here you can see this counter in action.

Won a used AMP 59250 crimp tool from eBay for 50 dollarydoos woohoooooo. (these retail for ~USD1400 new)

The 59250 is on the top/right, I like that it can do both sizes of my old tools (47386/47387) and it's a bit more compact to boot. The closer handle distance means it's a bit easier to squeeze/grip with my girly hands but the actual force seeeems to be about the same as the others.

Looks to be working just fine but I'll have to do some DIY tensile strength testing later. For my home hobbyist use I think it's more than adequate, a quick test shows that I have no chance of pulling a crimp terminal off a wire with my hands (the spec for 16awg wire was something like 20kg force from memory).

I got myself a laser "pointer": A 270W 915+980 nm diode laser for a price that was probably below scrap metal value (guys, don't ever start ebay auctions at 1€... [unless it's for stuff that i want, then it's perfectly fine]).
Not quite sure what i'll do with it, as it was purchased because of cheap and not because of need. I'll probably take it apart and sell the optics as i do not plan on using a laser that requires 50A@25V (good luck trying to find a power supply for that thing).

And of course it's not any old diode laser: This is a made in germany, no expense spared machine. Just take a look at the top cover, it looks suspiciously like someone took a 40x40cm aluminum chunk and removed roughly 90% of the material... The aluminum alone will set you back nearly 100 backs.

@jogri What a score. Are you sure that milled ingot is just aluminium? If it is, then it's likely to be some alloy they make into satellites. :-+

@jogri 25V 50A is not that difficult. If you have 3phase power supply at you house you can try Simens SITOP40 PLC power supply.
I found this version cheap on ebay, although used, quality is perfect.
Can you give us more pictures of this masterpiece? Especially driver board that can handle 50A?

NanoVNA SAA2 from Hugen. Really good device, compact, and performs reasonably well for its intended applications. Kudos to OwO and the team.

One problem with the Hugen version, however, is the lack of proper calibration kits. The included cable is male to male, but the cal kits are also male, so an adapter is needed thus compromising performance. Also there's no place to enter cal kit factors, but I guess for a simple antenna analyzer-oriented VNA, this should not be a problem. Still, details could be improved.

Also the batteries are not properly fixed to the device. The tape went loose and the battery rattles. I had to re tape it.

Finally, the battery indicator LEDs are kust too bright, so I just removed all of them. Probably not the best idea, though, as the 2.8" version does not have a on screen battery indicator.

For me, I plan to use it as a TDR, and I'm still exploring and experimenting with its menu.

Here are some more pictures/comments about my laser:

-it doesn't have a driver board, they simply use two pairs of massive copper(?) bars, the eigth individual diode bars (per wavelength) are wired in series. Switching is done via a transistor (blue arrow) on the positive side, other than this, a cap against ripple and a hall effect sensor to measure the current there's nothing directly connected to the input terminals

-it claims to be able to tolerate 250 mA ripple current (well, even the ripple current could power a nice laser), it looks like they just connected the input terminals to a big capacitor (the blue thing zip-tied to a diode bar)

-it can provide you three different wavelengths: one >1 mW 635 nm alignment laser (orange arrow) and two 915 and 980 nm diode arrays with 135 W each (i guess, it just states 270 W total). The entire setup you see on the pictures is duplicated on the bottom level, probably the array for the other wavelength

-each one of the four blocks contains two diode arrays, the beams get combined, pass a semi-transparent mirror with a power meter behind it (top left corner), pass a tilted lens(top middle, the large brass plate), go through a few dichroics and get combined with the other wavelength beam. They probably use another dichroic to get the 635 nm beam into the main beam

-nothing quite says "serious laser" like a watercooled(!!) fibre... Yes, those two blue hoses are there to cool the optical fibre. Why do i get the feeling that such a fibre assembly will probably cost more than my entire home lab?

-i still don't know the exact specs of this beasts as manuals are just non-existent. Judging from the model number (Optotools 270-30) and other lasers from the same company it seems like it's a 270 W, 30 mm mrad laser

-they "might" have overdone the thermal mass: Even though it is just 40x40x20 cm small it weighs 40kg... Well, at least it won't get toppled over accidentally

-i found this link to a evilbay offer for a similar laser from the same company: It just has one level so you can see the individual components more clearly:

Ah that looks familiar, I also have one of those.
Is this one fully working as per front so 0-45V and 0-70A on 400V three phase power?
I ask since mine is one of many coming from a dutch company and seeing the 12NC dutch company sticker on the front I suspect the same.
Delta modified them in a special way so it does not act as the original design.
Mine is more like 0-60V and 0-45A strange behaviour in a fixed power configuration.
Via via I have gotten the reverse modification instructions so if interested contact me. I have still to do the modifications myself  :)
