A Fluke 8842a from Hungary? If so, it was the same price before Dave's video.

A Prologix GPIB USB controller, The webpage http://www.ke5fx.com made me go for this particular unit

It was from Germany. But right, with all the extras the price was good and maybe not increased because of the video.

Picked up this Simpson Voltmeter at my local Surplus store.
Gotta love those probes!
Six badly corroded D cell batteries dripped over printed circuit board.

Anyone familiar with this Model Number?

[Johnny10]

Inside is clean.

Simpson 400 insulation tester, too bad you are missing the front:

A bit under 2m of 38mm ID wire-spiral vacuum hose. Au$47, ouch.
Also a KF40 90 deg elbow, stainless steel, from China so much cheaper.

Agreed. I gave him the benefit of the doubt on another post. Wasted time.
I'm surprised there is no link to a sale page.

Not bought today but a couple of months back............. and just got back from 2 days of hard out quad bike riding.
Winter Buster quad bike tour on the military land at the Waiouru military Training area in the middle of NZ's North Island volcanic mountainous central plateau. Stunning scenery.

Highly recommended.

Guy, next time you are going to grip thread in the chuck, grab a trio of thin aluminium strips and make some soft jaws out of them, which grip very well and do not mar the work at all. Sorry, do not have that 40mm vacuum hose, and yes it is bleeding expensive, especially as I had to buy a 30m roll of the 2 sizes I needed, so have been simply replacing the sections as they get dirty instead of cleaning them. If you want to cry order the food safe version of that hose, with the same PVC wall but with stainless steel 308 wire as the reinforcement member. That stuff is expensive, makes Watson Marlow Marprene tubing look cheap by comparison for the same diameter pipe.

I got a "True Position" telecom surplus GPSDO card and (after some initial frustration due to my not realizing how much GPSs have improved in the last ten years, in terms of dealing with non-optimal antenna placements) its working well.

It should provide me with a 10 MHz frequency standard to use in other devices, as well as a high quality 1 pps timing pulse which I can use for a great many timing-related things.

Now I am working on a controller and also need to figure out a good way to make that time and frequency data available to more than one other device without degrading it.

I look forward to having a second NTP server, for example, that uses it's 1pps, to compare to my other server that uses a tiny GPS as its source of timing data.

I can use a slightly modified video distribution amplifier for the 10 MHz - the 1PPS I have to look into, so I can preserve its fast rise time. Its a good way to learn about an interesting area.

Yeah, I know. But I needed make a bunch of those things, and will be needing to make more later. Plus needed to be able to remove from the chuck and put back, still centered. Fiddling with loose soft-jaws didn't appeal, plus crap repeatability. I like my thread-grabber collet thingy better.

I can live with it. Amusingly it isn't even really 'vacuum hose', just hose that doesn't crush under vacuum. Because it has a smell (PVC smell) which means it outgasses some bunch of complex volatiles. Fortunately where it will be used, this doesn't matter. It's only for the big rapid-roughing pump, and has a bellows valve between the hose and the chamber. That will only open for a few seconds during pump-down, and if I get the timing right the volatiles won't backflow into the chamber.
Bought this because I didn't want to even find out how much 1.5 m of 45mm dia stainless concertina hose would cost. Also it's nice to be able to visually verify the pump oil hasn't sucked back up into the hose due to some goof, like the air inlet valve not opening.

Today I bought an old Sony Video 8 handycam for 10€. Why? just because I had a crave to take apart something.
Always amazed at the tech density in these devices, and still hours of fun ahead
Glad Im still like a child 

[TiN]

Three 20fA/200V...1A SMUs for 288$.

[lukier]

Three 20fA/200V...1A SMUs for 288$.

I guess that's not Keithleys 2400 or something similar but HP 41420A

Bet most of the small 4v electrolytics on those boards have either leaked or gone almost open circuit though. Sony could never make those capacitors reliable, and they always are a ticking time bomb on Sony equipment.

Mhm... I bought one 41420 year ago, which has self-test error and large offset on both V and I, but works. And by seeing bunch of other 41420As with listed price, couldn't let it pass.
However now I have more modules than slots available in my 4142B. It will be renamed into "unshippables" once all assembled. Even with aluminum chassis/shields it will weight over 40kg. I don't know how I will move once my rent is out

I know the problem - in the recent months I scored Fluke 5440B (repair in progress, some DIY required), 5200A (seems OK) and Wavetek 4600 (repaired) and combined it is around 65kg. These things are beasts, but it was orders of magnitude cheaper than something like Fluke 5700A. I don't want to buy Fluke 5205A for 1000V AC range, as it is another 55kg, so I'm thinking about using Kepco OPS-2000B, 2000V opamp to do the 10x or 100x gain from 5200A.

Having recently chnaged over to a modern flat screen TV, I found out the sound to be poor compared to my old CRT TV.

So I just bought an old surround amp (Yamaha DSP-AX630SE)

[peteb2]

For far too long now i have not had a decent high current, current-limiting selectable,  variable voltage 230V/115V source at my workbench in my workshop. I see more and more sad SMPS that the owner is desperate to have working again and you have gotta be so careful as we all know....

So i started my next project with this monster (for me) isolation transformer; Specs: 7.5A @ 230Vac or 15A @ 115V....

Next item will be the variac. I'll probably build the whole thing open frame but covered with a 1/2" thick panel of clear acrylic just in case... and use four 60W 'vintage' E27 clear glass tungsten filament bulbs as the current limiting devices... so the thing looks like something out of 1930s Hollywood mad scientist's set.

BF-2A battery testing fixture. No more sticking batteries into mini vise between two coins to do some load or charge tests It allows for a true Kelvin connection with proper pogo pins for voltage sensing. Impressive build quality, too.

These look nice for testing of 28650 cells but I suspect will not handle the short circuit current of the cells. Shame

There's no photo of you - here you'd just deny it, and they couldn't identify you.
Cool number plate, BTW

I purchased my first DS1054Z oscilloscope today finally from www.rigolonline.co.uk, I'm looking forward to cracking it open tomorrow.

HP 3326 dual oscillator - 13MHz can be either different phase or frequency.  A mere lightweight at 26kg of vintage iron, well mostly aluminium. Arrived from USA - one cracked foot. Works fine - bit of age softened plastic inside.
I am also a bit of a LED display fan.(The 'cool'  display tech of my youth).

Are you sure it's not a kit? It immediately reminded me of:

Yay, that brings back memories! Especially the inductor, the clip on heatsink and the Red chicken head knobs... and of course the mustard caps, all Philips of course.
