A few things for a regulated-temp, vacuum hold-down hotplate I'm making. Hopefully to be able to non-destructively disassemble an iPad Mini 3 and other such glued-together devices. Most of the hotplate bits are salvaged stuff I had lying around, like the setpoint controller, timer. heating base plate, SSR, buttons, etc. But for the construction, assorted mechanical stuff:

* Sheet of 6mm thick aluminum. An offcut.
* Two sheets of silicon bonded mica. One 5mm thick, the other 3mm. Also offcuts. I only needed a little of this, but think it's bound to be useful for other things. Expensive stuff - that's $120 worth in the photo. Biggest problem is how to cut it. Like mica washers it delaminates very easily.
* Tube of high-temp (300 C) silicone sealant.
* Bunch of stainless steel M4 & M5 screws, mostly button head hex.
* An M4 taper tap, to replace the one I ground the end off to make an absolute bottoming tap, for blind threaded holes in the 6mm aluminum sheet.

I get the impression that Welectron are a pretty good supplier.
3DB

hmm. I've posted an innocent question about tracking number using web-form on their site, and they never responded. This is very strange for a pretty good supplier.

I just ordered five 0.2m GPIB-cables from overseas (US). Special feature: The connector at one of each cable has a 90° cable outlet.

And yes: GPIB isn't dead. In my opinion and for my test equipment that's awfully true.

Ah, the Triax Cable I ordered in October last year was delivered to me finally.
The Triax connectors I ordered from mouser around the same time are still not delivered because I ordered the together with special LEMO connectors that are announced to be available around April 2018.

A HP 11708 A 50 MHZ precision Reference attenuator.
Makes the 140 Euros for the 8484A Power Sensor (Option 003 -no attenuator -euphemism..) -that I thought were a good price- look not so cheap: The attenuator is 2/3 what I paid for the sensor.
Still little money compared to prices for new ones. But still real money...

Now waiting for delivery. *groar*

BTW: HP 437B Power Meter and 8484A Power Sensor I recently acquired are working fine. I could verify the attenuator of my HP 3335A Synthesizer is working within its specs as far as the Power Sensor can measure (-65dBm; 3335A goes down to -86dBm).

My $129 laser engraver has arrived. Long live prime same day shipping.

Edit: added is a sample of laser engraving on molded encapsulant, here a Standex Meder quad reed relay in BGA package. Being engraved is the "T" on bottom left corner.

Care to share a link to the listing?

Interesting Laser for the $$

Today because I 'need' an accurate Frequency standard to cal the 40+ year old crusty counters I own

As it is fairly new teardown will be done to see what is actually inside the box.

eBay auction: #https://www.ebay.com.au/itm/GPSDO-10MHz-GPS-Disciplined-Clock-3-sine-and-3-square-wave-2-1PPS-Send-GPS-ante/253375324294?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I also brought a 4RU road case with test gear enclosed for $100 delivered but more on that later

That is a very nice meter

. The newer 298 is slow and hungry.

Meanwhile, I bought a bucket with a fan, to get higher than 20% RH.

Thanks, as I've been salivating for this particular 189 for years

, and had been waiting to get a decent one with decent price.

At least to my self, this 189 is almost an ideal handheld DMM. I own 87V and 287, and it has instantaneous boot time and really hate 28x booting time, with an ultra sharp LCD segment display not like 28x dot matrix rubbish, size wise is equivalent to 87V's size which I personally prefer, and full of useful features for electronics activities, that made the 87V features look crude as its more suitable as an electrician DMM. And its AA cells powered too.

Did you do the single line fonts too? Because those tend to look a bit better than the regular scanning type engraving.

Should we be worried that you are going into the fake chip / relabelling business?

The mystery contents of yesterday's road case is a little 25kg of Rhode and Schwartz obsolete gear. Destined for parts and a nice modular plug in case / power supply for me. If I value the case at $100 this one was free

An Advantest R3131A for $580 shipped. It fails the autocal but the rest seems to be working.
My first spectrum analyzer!

hscade · « **Reply #5490 on:** February 14, 2018, 05:31:35 pm »

Because the last post was about a spectrum analyzer and second last was equipment of Rohde & Schwarz I combined both!

I'm sure it is some sort of joke I failed miserably to understand.

Still there's no excuse for it from a relatively new member.
