. for now, i dont tear it apart (sounded like dave from eevblog, sort of), i'll think first what i could possibly do with it, and when time is right, box'll find other use, it has already couple places for PCB board, if you look closely you can see them. But, this was again great education, thanks guys .
haha, seems so derstorm8, i measured, it adds resistance by 1k steps 0-10k, with very small tolerance, well at least my dmm's (i tested with two) show no change at first digit all the time.
so, overall, got this at 10€, so not bad find?
edit: i mean derstrom, not derstorm
aaand here come's my favourite question, what do i do with it? well honestly, i dont know
. ''friends till ignore do us part?''? but, i follow dave's suggestion, especially when i read ''made in china-or-other-mumbo-jumbo-country'' (no offence, i'm no racist). and what boceomes prototyping, i do it pretty regurally, so you newer know what you'll need when designing ''bomb''...speaking of which, teacher demonstraded the power of 'lytics: he shorted cap-bank IIRC 1.6 farads@320v, quite a bang. the caps were from old UPS, from some factory.
ok, matt
haha, so you too know the eevblog
)
.. he just connects cap to mains, and it should be seen from measurements.
i watched one daves rewief about atten smd-hotair station, and read about dangerous situtation: live was soldered to chassis, safety-earth and live had swapped places, that's why i check chinese stuff, and sometimes even what i use already.....haha, funny thought, my real name is Atte, and brand name atten, means almost attes
hmm, interesting april fool prank idea ;D my one teacher uses that technique on normal teaching procedure: if measurements are not taken with care, mess tells it all
However, I feel it necessary to mention that I have purchased items from Chinese companies that turned out to be very well designed, very well put together. Higher quality than you get in many other places, even. So don't judge a book by its cover--do a little research on the company before making a purchase. That's what I've learned.
I don't usually destroy electronic components on purpose, even for a demonstration. While I've done it before, I generally just let the students make the mistakes themselves. They tend to learn it faster that way, though I imagine it's more fun for them to see me do it
Okay, well I keep saying "my students", but really it's just the students in my lab. I'm an electronics lab assistant at a university, and I often help students when they're having trouble with their lab experiments. Technically they're not "my students", but I still consider them to be since I tend to do a lot of tutoring and other types of assistance.
It's amazing how times have changed....
. About learning the hard way, i've learned it couple times, placed transistor wrong way, and took 100r resistor for 1k but thankfully, none caps blowed on my face (knocks wood here....) .
