This un? Nope, just crustification.

[bd139]

I didn't even see that one 

Time to get my eyes tested 

[mnementh]

Not the tant... the little one in the foreground looks crusty/cracked. Yup-that one.

If you are interested in tinkering (electronics and more), one can find here quite a lot of inspiration.      

Example:


Please note his rancid soldering iron and his soldering skills ... 

Was that a Metcal as well?!?

I have a T12-B which appears identical; here it is in my $9 FX-9501 handle. I don't use it that often, aside from XT-60s and drag-soldering things like this TSSOP-8 ROM chip where the large thermal mass is required for short dwell time at low-ish temps. Otherwise, it would probably be just as crusty as his. I use flux religiously and wipe the tip before every contact; I care aboot a clean solder joint, not a pretty iron.

...Also fuck batteries. Bastard all of them!

Shutcher dirty, dirty mouth!  Some of my best TEAcquisitions have been the result of battery fuckerization!

also: job security, mutherfucker!

Talking getting your eyes tested, spec savers have been reminding me now for about 9 months that I'm overdue for another test  I really must go and tested again.

Haha, all the same I agree with bd, there are bastards 

[mnementh]

Leaky batteries are like Republicans... evil & messy as fuck, but there's profit to be made as long as you don't git any on ya.

cumon, I have rarely seen someone as corrupt as Pelosi.

in other news, the graphics card works.
It's currently blissfully burning electricity to support the banksters my hubby and heating the flat (heating in my home office room is not really working)

As for the appliances bit: the idea is to have a mostly autonomous gizmo which can be reprogrammed on the fly (e.g. by shoving in a new SD card), has video processing in hardware (makes it easier for autonomous recognition and target aquisition and provides the data via a REST api that can easily be queried or interfaced into other systems. yes, you can do all of that in software, but FPGAs are far more elegant for what I have in mind.

Let's see. If that does not work out: boss came along and told me to
- get my system officially 24/7 ready
(I am sorry Dave, but I cannot do that. Going out and having all those managed services providers lined up against a wall is considered illegal where I come from)
- plan for lotsa integration work

oh well. I am sure that there is more than enough to do ...

What is it with skanky mouldy 'scopes on ebay at the moment?

Oooh got to get me some of these mangled probes

[Specmaster]

Easy enough to make your own mangled probes  WTF are people thinking, those probes will no doubt, like that manky TDs210, not sell, serve them right

That guy almost always over-values his gear. I never even bothered to save him as a seller, and I have really low standards!



It lives!




Also checked the other functions, works really well, don't even think I'll need to clean the board properly.

One interesting wrinkle is the rotary switch MUST be in the AC A position if you've had it apart, as it apparently has no position sense, and defaults to that on power-up regardless of the actual switch position. Weird!
After that it remembers the position just fine on power cycles and even battery removal.

I might try and leave the batteries out for a bit longer, see if that makes it reset...

Anyhoo it works fine on the 2 Turnigy LSD Ni-MH I put in it, no leakalines for this!

Meanwhile, this NIB SDS1102 is a whole 75 quid more, and shows up right under it as a suggested alternative:

Ehhhh... it was too quiet in here. I felt a need to agitate a little.

just a little; I promise.

I think Saskia wants some Mangled Service Providers. And I have very little doubt she'd rather do it herself.

I got a HP 8568B off him for £120 
That was about 5 years ago, collection only from Yorkshire. Fortunatly SWMBO wanted to go to Holmfirth to buy some fabric, so I said OK, I'm just going for a drive while you are doing that

Other things to consider are (assuming I wanted a mouldy TDS210) local collection, which would be very local for me, 25 miles or less each way, versus shipping from West Coast US, with all the risks and concealed costs that implies.

Was it as skanky as that TDS210...?

I like quiet.

I did say almost always...

@mnem usually his stuff is clean, just overpriced.

Maybe I should add him back, for the one prospective diamond in his barn full of turnips.

Spotting the Gossen reminded me that I hadn't trawled eBay for any Gossen stuff for a while, so I did. Turned up this oddity (https://www.ebay.co.uk/itm/Siemens-Multimeter-A-D-GOSSEN-UVA-D-Multimeter/383889451073?hash=item5961982841:g:8UMAAOSwcbpf9GFv). I don't think I've ever seen this done before.

No wonder the price of TEA is getting higher on ebay 

At least he is using them and not trying to make guitar amps or lamps out of them.

There seems to be a few people using old TEA for creating music & weird sounds, I linked another of that guys videos last year where he visited a studio full of old TEA (quite a lot of it was HP).

It was a search for info on a lock-in amplifier selective amplifier that found that.
I guess stuff we don't have much use for is very useful to them.

David

Interesting. I think I missed your post back in november.

Actually I got that wrong earlier, it's not the lock-in amplifier I have but the 189 selective amplifier, he is using several of those as band-pass filters.
I watched another today, he is using word generators to sequence beats, all kinds of function generators with VCG/VCA inputs & pulse generators for making the sounds (some vintage tube based Tek ones in his setup too). The boat anchor grade Brüel & Kjær filters seem very popular again too, also has some NIM BIN racks too.

After someone posted about one of those here before I bought a pair of them, trouble is neither work & no service information is available as far as I can tell.

It appears by the symbols that it can measure ACV and DCV but where is the AC/DC switch? 

Edit....nevermind...found it. left most switch on the bottom right.
