That's a recent one too - has the new logo.

Congratulations!

But you have to wonder .... how come the price?



I'd have been tempted, but the unknown was outside my comfort zone and the shipping cost would, no doubt, have been not insignificant.

I think you missed my point... to completely repurpose said chill air delivery for keeping Butthead Bob frosty. That said... yes, I know it's silly. That was kinda the whole point.

That won't work, either. BTDTGTTS. (Yes, actually, I've worked in a morgue!)

I'll see your morgue and raise you a crematorium.

No, no, noooooo... let's not replay WebNX/Gorilla Servers "incredible burning backup generator" scenario again...

Too fucking soon, dood. Too fucking soon...

Best never to ask questions like that

When a seller on Amazon is selling a Rigol DS1054z for $82. And that's in Canadian. Ummm what? Not touching that with a trillion foot barge pole!

https://www.amazon.ca/Rigol-DS1054Z-4-channel-Digital-Oscilloscope/dp/B012938E76/

It has to be a weird product mix up.

I'll let you know I just ordered one   

Hmm got a fedex tracking number. Something is coming 

Well well, look at what Fedex just dropped over here. If i'm not mistaken it's a 65$US Rigol scope

Lucky hoser...

Kosmic doesn't have to ... he's come out a winner.


Me...?  Just curious.  Could be anything from "fallen off the back of a truck" to a surprise inclusion in a bulk acquisition ... or maybe a part of a "Storage Wars" episode?

I tried... they wouldn't let me have it. binches.

And yes, I'd have taken at least 4 units.

[xrunner]

It's working fine. I need to unlock all options now 

Wow. Nice score dude. 

[Brumby]

+1 on the Jammy Git.

[Specmaster]

+2 on the Jammy Git award, IIRC I tried that link when it was originally posted and they wouldn't ship to the UK, otherwise I'd been in for one of them as well.

Well done you, enjoy it.

Interesting, didn't know they had an 500uV option for the DS1054.

Hardly much point as the damn things are so noisy.

[Carl_Smith]

Apparently they had to raise the price to make back for their losses on the $82 ones.

At the risk of becoming a member of the TEA fraternity, Friday morning I walked into a thrift store looking for a dead toaster (as a source of some NiCr wire). I left with a dead toaster and a Tektronix 2215 CRO. A month back I acquired a HP-8111A function generator. The HP had a aged/cracked Rifa safety cap (seems to be a common story), but otherwise appears fully functional. The Tek scope shows minimal signs of life (i.e. beam finder works), but the input channels are not displaying. I’ll look into that when I have more time.

That’s all, and no I’m not looking for more vintage TE (or, why don’t I ever find a nice spectrum analyzer).

Same link but different seller. This one is from "Electro-Meters Co. Ltd.." and I bought from "Spreetail".

Yeah I just saw that

It's like Hotel California - you can check out but you can never leave. 

My M.2 upgrades are done. Main SATA SSD drive (Windoze) cloned to nvme drive, screaming fast now. Secondary SATA platter drive holding firmware moved to M.2 SATA. Good speed compiling on that also. All's well and nothing can go wrong now ...




Hmmm, perhaps I'll just set the original drives on the shelf for a couple of weeks untouched. No I'm not paranoid, no no no.

Amazon does that; when a vendor sells out of a particular item they automatically link to the next one in the list of vendors. No surprise there.

I need less Mexican flavor.

[bd139]

Typically the moment I am about to drop a load of stuff on eBay because it's the only items there, some bastards have listed other copies of the material. Looks like I'm moving with it  . Really should avoid the hamfests for a bit 

On that, having to skip Newbury annoyingly because of some property handover shite on that day

The product description is great.  Only good for 50mhz, oh well at the probes have three times the bandwidth. 

Brand:Riorand; the ds1054z series is the new economical digital oscilloscope to meet the customer's application demands with its innovative technology, industry leading specifications, powerful trigger functions and broad analysis capabilities. 50 mhz bandwidth with a 7-inch display and ultravision technology as well as a host of options. Add the optional analysis, decoding, deep memory, and integrated 2 channel waveform generator for a powerful 4 channel scope at an exceptional price. Standard probes: rp2200 150mhz bw passive probe:4 sets.

VOLTAGE REGULATORS

I don't have any low current ones, which I guess makes sense since I have only beefy TO220 and TO3 packages. Since these can put out 1 or 1.5Amp, why would any manufacturer artificially limit them to 500mA ?! So I guess the only 'L' 500mA ones are those supplied in small packages like TO92 or SOT23 surface mount something or other. I don't have these.

OK Murphy !

I have just finished sorting and organizing them all... just need to update my spreadsheet and print labels.... tomorrow. 2AM here I am going to bed.

So out of nearly 100 regulators.... guess what, yes I found ONE that proves me wrong... ONE TO220 package that's low current ! 

But it's not an 'L' , it's an 'M' !

A 78M12 ...so I pulled the datasheet and yeah, it's a 500mA version ! Why... why do these things even exist !   
Makes for a smaller pass transistor inside, makes the regulator half a cent cheaper maybe ? I guess for high volume commercial electronics it can count ?! 

So the 500mA version is an 'M'... so what is an 'L' ? I pulled the datasheet for that one as well. It's also a low current version indeed, but not 500mA, no.... the 'L' is only 100mA ! THESE are indeed the ones that come in the tiny packages, TO92 and surface mount.
Datasheet says these are intended mostly as an improved " Zener + resistor " replacement. I guess why not, makes sense...

Well thanks everyone for your participation, that was quite a refresher on these regulators. Think I now have my basics right...

 

Didn't you find any TO-3 ones with a "K" suffix? The LM323K is 5V 3A, for instance. The LM7812K is rated for 1.5A.

And 78Sxx in TO220 are rated 2A. So you have neither LMx09 nor LMx40 regulators? And neither LMx17, x37, x50 nor LMx38? And an LT1070 should also be at hand when needed! Vince, you really need to round out your collection!
Tsktsktsk

At least, I've sent him two Tesla MAA723H.

You'll probably sell it. The £30 auction one is only for 3 days, and then it will become too expensive to relist. The £60 one is untested. Your's is well displayed.

Not sure I'll bother with Newbury; I'm 50% further away than you are.

Mendips is the next for me; they will probably have imbibed too much Pb, Cd (from vegetables in their garden) and scrumpy.  But is it too close to miss.

That went quick ...

Turn the brilliance up and set it to XY mode. If you can get a spot that moves up/down/left/right then the problem will be in the trigger or sweep.

Get the service manual, and follow the faultfinding instructions.

That’s all, and no I’m not looking for more vintage TE (or, why don’t I ever find a nice spectrum analyzer).

Patience, dear boy. Patience. Especially for decent spectrum analysers
