Toroidal transformers
« Reply #7900 on: December 07, 2018, 02:50:08 am »
As previous post, the same visit to local recycler, grabbed 2 used step down transformers, 4.5 bucks.  :P

Smaller one -> primary 2x115V, secondary with 2 windings : 15V@0.5A and 9V@1.5A
Bigger one -> primary 2x115V, secondary with 3 windings : 10V@8.3A, 22V@2.7A and 24V@2.7A

What a weird secondary voltage windings at the big one that is made in USA.  :-//

... again, same seller  :palm:, 1.5 bucks a piece for used Vicor VI-BAMD-EM module, a power factor corrector and booster for pre DC to DC converter.  :P

Scissors!
These Engineer scissors are really cool. I have the same ones, they can cut quite a lot of things.

Yup, I got a new bank card so had to destroy the old one. They cut through it like a hot knife through butter. I'm well happy with them, I have the long nose pliers too. They are also well made and nice to use.

Nice cables! What do you use them for? I haven't seen the connector on the ends of them before.

I just bought this to measure that resistor in the bottom left of the image.

100fA resolution anyone?

I have a pair of bandage scissors that I bought for a dollar at a yard sale years ago because a friend showed me you can cut a penny in half with them.

Nice cables! What do you use them for? I haven't seen the connector on the ends of them before.

The connectors are on the ends are either SMA or 3.5mm precision connectors. They are used for RF work. The cables themselves are built to a guaranteed maximum loss and maximum phase error. The SMA cables are rated to 18 GHz, the 3.5mm cables are rated to 26.5 GHz. You can connect the SMA to the 3.5mm cables. The 3.5mm connectors use an air dielectric instead of PTFE and are built to a higher standard of precision. That also means they are very delicate. Torque wrenches are used for all mating connections. I use them with my 26.5 GHz network and spectrum analyzers.

I bought a Fluke 101 and case for my toolbag.  I was disappointed in the inaccuracy of my Aneng 8009 on voltages when I checked it with my DMM Check plus.  I still wanted something relatively small and for $40 USD, it's a good enough deal.  I probably should have bought this first instead of the 8009 and the 8008 that I have as a back up.

GreyWoolfe, this is interesting info; did the Anengs start to drift continuously or were they subjected to an... ahem... "event"?  :-BROKE

If the former, that says a lot about their build and reliability.

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...

48v 600A Contactor for upcoming electric lawn tractor build.  Saved a bit of money using eBay 10% off coupon code PHYDAYTEN - today only!

Also purchased one of those cable extenders to be used for Tektronix TM500 series plug in repairs...

Actually, no.  The only event they both went through was the well documented mods for the more stable display.  OF course, I received the DMM Check after the mods were done so I don't know if I  :-DMM something up doing the mods, though I doubt it.  C'mon, it's adding a couple of caps and replacing a couple--not hard to do.  The 8008 was much closer than the 8009 but not near as good as my old Fluke 27/FM.  They live a quiet life in my company van as I needed a small multimeter accurate on low ohms reading and they both do it very well.  The only voltages they have been exposed to was the DMM Check.  They are much better than the red HF meters, I found 2 of them NIB with fresh batteries that were an order of magnitude off for what I needed.  Quite embarrassing as this was at a training session which prompted the Aneng purchase.  After more pondering and rumination, I may need to do quick voltage checks including mains and I don't really trust the Anengs for that.  That's what prompted the Fluke purchase.   I will still keep the 8008 as a spare but I may Wildarize the 8009 just for fun.  I haven't used my 2 pound hammer for anything in quite awhile.  I will see if the voices in my head tell me to keep it intact. >:D

Actually bought a couple of weeks ago. Good investment for about $150 delivered (amazon).

Cheap vna that has good reviews and indeed it does work very well for testing out antenna prototypes.

Picture is of a prototype moxon antenna for lora at nominal 910MHz.

I also purchased Matlab home (about $150) and the antenna plug in for $50. I have a PCB prototype layout of a moxon antenna that I'll have to send it to a cheap PCB fab when I get a chance.

cheers,
george.

Really bad news. HSC Specialties "HalTed" of silicon valley will be closing January 12, 2019.
https://www.halted.com/
There's a big sale until then.Today I grabbed a few things.

A couple of toroidal transformers at 50% off. This one has two 120V primaries.



This one I'm still looking for specs.



These super cap banks were for server memory backup (SCU CA05954-0920). Each cap is 47F/2.7V. They are currently $3 per bank.


I'm really gonna miss this store. SV is really drying up.

100 fA = 0.1 pA = 0.0001 nA = 0.0000001 uA. Not so much Amps anyway...

The SMA cables are rated to 18 GHz, the 3.5mm cables are rated to 26.5 GHz. You can connect the SMA to the 3.5mm cables.

I bought some proper flux cleaner the other day, after years of using isoprophyl I'm shocked at how much better this stuff is! I really wish I'd found it sooner.  :palm:

The impossible often has a kind of integrity which the merely improbable lacks.
