hm... that looks like a nice thing ... i.ebayimg.com/t/…$_57.JPG

and again buggy chat ...

@ThePhoton On the one hand I account for stocking and/or purchasing as well. On the other the bulk of my 74-based life was pre-single-gate-for$0.1 times :-)

Though neither is any reason for a one-off hobbyist

Where my hobby life was always weird and special

@PlasmaHH Looks like a regular late 80's / early 90's digitally controllable auto-transformer

@Asmyldof yes, but with 25A it is not one of those you see very often

good morning

@Asmyldof I finally had time to read your answer, thank you! I'm really sorry that it took that long, and I'll probably have to re-read it a couple of times before I can fully appreciate all the details in there

@Christoph Good morning. No problems. It's not my concern when you read it, just that it hopefully helps.

I would have read it last week while I was in wacken, but the internet there broke down on day 2

@PlasmaHH 1. Linking just the eBay picture doesn't convey those details. 2. I used to have a 3phase 32kVA one. Took it apart (and grinded off the 3rd phase leg off the transformer which came behind it to turn it into 32kVA 0VAC to 60VAC with a 100A bridge rectifier and cap-bank) on account of our prior discussion of Dutchies not regularly having 3phase at home

lol

@Asmyldof I thought it was visible from the sticker, but now that I zoom in I see that it is too blurred

Fun fact: the 3rd leg of a 50Hz 3phase 32kVA transformer makes for an AWESOME electromagnet!

hm, I wonder if that guy will take the idea of building a weatherproof tesla coils as a replacement for his generator dummy load seriously ^^

@PlasmaHH What question did I miss?

@Asmyldof ah, none, was talking about a real life phonecall...

@PlasmaHH Then you definitely need to tell me more.

@Asmyldof nothing spectacular. that guy has a wind generator on his premises and a few weeks ago there was an event where there was much wind and he had to divert into his dummy load and fried that load and we talked about how to add some safety capacity and that its not so nice that the energy is wasted and what useful things we could we do with it when we can not feed it into the grid or store in batteries

@PlasmaHH How about hooking up a second windmill of same size behind the first one that will start blowing back when turned on? >.<

that sounds brilliant ^^

yeah and then watch them fight each other to death

@Christoph That's what we call an automatic feed-back system

@PlasmaHH I know! Right?

hm, in that question no one thought about checking if the actual LEDs are faulty, or if the driving circuit is faulty...

Good point

But I doubt it

@Asmyldof if you doubt you make a do out of u and bt

hmmm ... somehow that seems to work better with assume

morning @guys

@jippie .... I guess you're rested... huhm?

Guys, remember the cordless ESD wrist straps

can you imagine the humour/horror on my face seeing these used in production over at our pcb house

The fuck is very what in channel today this

da fk did i just read

we are on the same page

@crasic I think, maybe, possibly, fire the lot of them?

cannot, they did a bang-on job otherwise

Also, any experience with burn in for memory/cpu/flash?

need to write something, I'm guessing just write/reads from flash and ram, some sha crunching for cpu and call it a day.

See, frustration of EEVBlog dude was spot on, why the hell are they on ebay from china for $1. because they use them there :O

also the use was as a discharge point, they would tap the screw end of the wrist strap on a metal surface occasionally

very odd

@crasic That's exactly what I said when I linked an ad. "If they'd only include the caveat: Your screw needs to touch earth for it to work, even in tiny print" at least they'd not be implying it's magic

Although, of course, in an ESD sense that's still complete baloney

Yes, its silly, and they had a nice earth bus bar overhead that made straps painles

It takes all of a hundreth of a second to get to 1kV differential when handling certain materials or wearing certain clothes

@crasic Also, it's Dave

And possibly Dave2 now

The good thing about the straps though, is that it gives me yet another quality gauge

I ask a fab or whatever "Hey, have you seen these?" and then await the response

:-D

the way this fab is set up makes it basically a personal production line

for a small vol product this is lucrative

at the cost of basically 0 dfm recomendations from them

but gosh darn they are willing to fix any screw ups

head->desk on ee side

>.<

but hey, its not all bad, I like to travel

so any experience with cpu/memory burn in techniques during production
