Noticed and appreciated all of the above... I like that they deliberately made an effort to include stuff for Trekkers as well as Troopers/Jedi in their production, without making it too obvious. This is a time for Holiday Cheer, not feeling slighted. 

mnem
moo!

Not obvious? How much more blatant do you want it? 

As in "not bludgeoning you over the head, such blatant fan service that even the marching morons will see it" as opposed to "Yeah, it's there for me; if I'm a Trekker I'll notice". I felt it was done tastefully and in keeping with the season.

mnem
But if bludgeoning is what you want... ask your doctor if commercial broadcast is right for you.

I had a Lumina 950 Windows phone with 8.1 installed and then got a free upgrade to Windows 10, 20Mpix camera and I loved it, performed well, large screen and the camera was excellent.

The Lumina 925 unfortunately could NOT be upgraded to WIN10 so I stayed with 8.1. But it's now obsolete and no one supports new apps for it. Luckily my provider still supports the phone/text but that could end suddenly.

[mnementh]

In all fairness, nobody really supported it with apps when it was a current model. Fortunately, it came with Mobile Office and most of the gadget apps we take for granted baked in... and that Nokia GPS app was effing excellent. Functionally as good as Google Maps is now (aside from real-time traffic), and half as annoying with Googs always trying to "help you" do shit you were never interested in. 

mnem
Also, it could take a pretty solid punt. 

[mnementh]

... and I found papa med a new Christmassy avatar, will he use it? 

Not unless one of the hands is photoshopped ... 

Did that already... remember...?

hah. bumbug.

Asking TEA fellows, especially from Germany, any comment about this German made multimeter ? (photo attached) As I'm not familiar with the brand.

I've been offered locally, apart from my weak heart seeing moving coil meter  , what interested me is it claims its a true RMS and also has a switch for averaging too, and AC+DC or pure AC in analog display.

Or any other comments maybe ?

This little bad boy showed up, really impressed so far.  Yes its stable and precise to the last digit, need to see how the CTS reference ages, only been powered on for a few min, warms up fast, but slowing drifting. Going to let it cook for a few days.

Far as I can tell, this is the bargain of the century for a 6GHz counter.

Oh, found a HP 3410A AC Microvolt meter in great shape, same vintage as the rest of my HP gear, with matching manual, its on its way

The brand is Lucas Nülle, their website can be found here: https://www.lucas-nuelle.com/
They are specialized in producing measurement instruments for education and research, perhaps you are familiar with the brand PHYWE (PHYsikalische WErkstätte - physical workshop) which exists since 1913 and belongs to Lucas Nülle since 1988. ( https://de.wikipedia.org/wiki/Phywe - sorry, only in german available )

Your meter claims to be undestructable for voltages up to 1kV and for currents up to 30A and from the build quality it is one of the best you can get, imho.
Here are some details (found them here: http://www.selkagmbh.com/product_info.php?pName=analog-multimeter-p-27)

[worsthorse]

my mouser order arrived today, so i spent a pleasant couple of hours repairing the poorly done rework on the countdown board from the 184 and restoring the delay line to its former glory. replaced half a dozen resistors, three or four capacitors, and a couple of diodes along with cleaning up much of the bad soldering.



i don't know why i so enjoy fixing this old junk that no one wants or uses any more, but i surely do. 

[0culus]

It's really not old junk though...I think of it as carefully preserving and stewarding a bygone era of truly quality stuff.  No one builds electronics to survive anymore, outside of space applications.  Much of it is perfectly serviceable if it can be fixed. Sometimes other units may have to sacrifice unobtanium parts, but such is life.

Well for you guys who still have this phone, and have nothing to lose, well there is a Windows 10 port for that phone:

https://forum.xda-developers.com/lumia-920/general/how-to-upgrade-lumia-920-to-windows-10-t3451644

Currently no Android port for this model, but for others there is. Well there is one but no signal SIM Card, camera, accelerometer, GPS and internal microphone, since it still under development. But for any one interested: https://android4lumia.github.io/ I can't be held responsible if by trying this your phone turns into a drink's coaster, so please do at your own risk.

That's for the 920. I have a 925 and quite frankly I'm not going to bother or risk it. I'll opt for a new android phone. I will never, EVER, drink the Apple juice.

Same base hardware, half internal storage (32GB from the Lumia 920 to 16GB in the Lumia 925), different screen technology (AMOLED for the Lumia 925 and IPS for the Lumia 920) and different camera modules. So the update will work, although I understand not wanting to take the risk.

Grand-dad always said "Never do today what you can put off til tomorrow."

A swedish writer who was known for his hilarious stories about life in the part of Sweden where I'm from, Fritiof Nilsson Piraten, was a procrastinator of rank.  His tombstone states (in translation) "Here below rest the ashes of a man who had a habit of putting things off until tomorrow. He improved on his deathbed, though, and actually died January 31, 1972"

I don't know yet. Wishing to avoid another round of dumb mistakes, I stopped tonight after a couple of hours. Tomorrow I will ring out the connections to be sure I put things back together properly then re-install and test the board. I also have to replace four or five caps on various points on the 12VDC rail, along with a couple of transistors I blew up.  Once that's all done I can see if (a) I've found all the destruction caused by connecting 130VDC to the 12V rail and (b) whether I've cleaned up the cross talk on the trigger output.

Today I built the TritiLED, a coin cell powered micro light, used as a locator in very dark conditions (as an alternative to 'tritium' powered radio-luminous paints). It is supposed to last for years of continuous use off of the cr2032 cell. The author, Ted Yapo, of the project was on the Amp-hour recently. Details on https://hackaday.io/project/11864-tritiled/log/72301-v30-release
It fits inside a small lip-gloss container. Parts list (Digikey and Amazon) and software also included in the build details.
The biggest issue I had was learning MPLAB X IDE, PICKIT4 and finding a socket for SOIC8 as I like to pre-program my micros.

Lovely, I very much appreciated that AMPHOUR episode. What struck me was how he predicted battery life time of that device. He took the graph from the datasheet and got it interpolated in SW to get sort of "look up" table form the non linear curved lines. The rest was easy.
Anyone here have done something like this?

To me it looks like an IKEA multimeter.

To me that meter looks like it comes from the Eastern Bloc. Somewhere that they were trying desperately to prove their production prowess to the rest of world through extreme modernism. But missing the mark by a mile.

You have to keep in mind, those meters were built mainly for education purpose. When the teacher is doing some experiments in front of the class, e.g.
demonstrating inducting current in a coil, so those meters were used to show the measurements and everybody in the class was able to see it.



I by myself was also introduced in the mysterious ways of science with these instruments in my school.
And sometimes these instruments were used by the pupils / students themself, so they have to be bult rock-solid, bullet proof and simple to use.

That's why they are looking like some retarded things, but they aren't that bad.

Typical example ( starting at 4:50)
