I found it on ebay.com and bought it right away eight ours after being listed.  :)
Yes the keys are standard rubber keys. But since everyone uses them since the '90s even for Test Equipment costing 10s of k$ they can't be too bad, can they?
In fact, even the classic HP keys do get defective/inoperable..     :popcorn:
Personally I like cherry keys but I haven't found those in Test Equipment yet.   :-DD


Mentioning the high prices of HP 53132A's the PM6690's are even worse in that field. Yes, in fact they are a class up the HP 53132A, but I would only go for a Jammy Git awarding price.  :-DD
What's with the universal counters being so stupidly expensive? What are people doing that makes them so desirable?

Manufacturing & Assembly / Re: Ultrasonic cleaning and xtal ?
« Last post by Gribo on Today at 07:02:49 am »
I had failure (component out of spec) for a 26MHz crystal. Spec was 20ppm initial accuracy over standard temperature range (-10 to 50C), assembled product had 40ppm. We traced it to the ultra sonic cleaning process. Moved to standard washing, and everything was alright.

Microcontrollers & FPGAs / Re: SD card/SDIO 3.0 level translation solution

I have no idea how to do it smart ... but I have an idea how to do it expensively.

Connect the SD-connector to something like a MAX4996 and then to slow level converter to do communication at HS, then when it switches SDR104 switch to a separate set of pins on your FPGA with the MAX4996. Needs extra pins on the FPGA, but only one IO voltage.

Man I TEAd so hard this morning...found a really nice packaged deal on an HP 5335A universal counter (with ALL options, including the high precision oven timebase!) and a 5350B microwave counter for $500 or so for the both. Both clean and calibrated too. I've decided that I want to focus on microwave for my ham activities, so this is a great find for me.

Also got a HP 5350B. It's really a nice instrument.

General Chat / Re: Gnu/Linux Considered Harmful
« Last post by cdev on Today at 06:59:14 am »
In my experience, lesser evil-ism turns out to be a trap almost every time.

The problem is, as computing became more important in the world, Linux and open source which had managed to survive and thrive under the radar for quite some time, likely started to stand out as an uncontaminated control group that really showed how dysfunctional things are becoming everywhere else.

So now ...

*Looks up websphere*

Oh god.

IBM?  I can't find any info on it newer than 5 years, but I presume the "ancient versions of java" bit still holds.

i know how to open a laptop man, I own like 4 in about 5 year segments between 1998 to now. This one was just bullshit. I still prefer a old micro sized think pad to this new crap.

Bolts fuck up and fuse too, we have to use blow torches and magical fluid mixtures to get our cars apart.. but at least you can grind them or drill them or do lots of things. When a snap hinge system malfunctions boy is it fucked.

Seriously I hate this shit. I just had to fucking chisel into a god damn laptop with a fucking hammer to undo a snap fit. Now its in the trash. God damn. I refuse to even work on that dog shit.
[etc. etc.]

Sorry Coppercone, I think you simply missed the right point in time to put down your tools, take several steps back, let it sit over night. If you worked on the laptop in anywhere close to the mood you were still in while posting this, I am not surprised about the outcome.

General Chat / Re: LED bulbs - Darwin award enticement
« Last post by Gyro on Today at 06:53:02 am »
There's surprisingly little encapsulation on those LED packages compared to any others I've seen - the lead frames are almost flush the sides. I bet they would fail really quickly under any sort of mechanical stress. I suppose they get away with it because they are using full lead length.

When the system senses the plane is close to losing lift on the wings, it automatically commands a lowering of the nose to counteract the risk. However, the chief sensor used to predict a loss of lift -- known as an angle-of-attack vane -- was malfunctioning on the Lion Air flight. It essentially tricked the system into ordering a sharp dive.

Pilots are drilled on how to cut power to the so-called trim system if the plane starts to dive or climb on its own, but that procedure was never linked directly to a malfunctioning angle-of-attack sensor in training or the documentation.
This is going to be an oh s**t moment for Boeing. They screwed the pooch with this "safety feature". A blunder among blunders.
