seems i will continue to be confused about what is usb, what is pci-e over cable, what is thunderbolt and what is displayport

i can see the discussions of 'yes, plug the disk into your GPU display out for mining, yes, forreals'
Rotonen
2019-06-26 19:33:48
also as that's now essentially usb, does it or does it now do power delivery too
Rotonen
2019-06-26 20:31:17
Yeah, my mac book pro at work has a USB-C that charges the laptop, runs a giant display and other thigns
Fireduck
2019-06-26 20:31:21
it is basically insane
Fireduck
2019-06-26 20:41:14
laptops are all sorts of mad anyway
Rotonen
2019-06-26 20:41:31
the processors ramp up from 2A power draw to 80A power draw in an actual jiffy
Rotonen
2019-06-26 20:41:41
and the power delivery keeps up
Rotonen
2019-06-26 20:42:05
pretty much madness
Fireduck
2019-06-26 20:43:36
the only other category of device i've seen do that is an ohm sausage
Rotonen
2019-06-26 20:44:20
Is that what you call plain barrel resisters?
Fireduck
2019-06-26 20:44:34
no, it's an electrical engineering student trick
Rotonen
2019-06-26 20:44:47
you run household wall socket AC through a sausage
Rotonen
2019-06-26 20:45:17
electrical engineering tricks are usually great and terrifying
Fireduck
2019-06-26 20:45:25
the system is self limiting, the current and resistance spike up as the sausage cooks pretty quick before becoming an insulator before the circuit protection trips up
Rotonen
2019-06-26 20:45:30
quite safe
Rotonen
2019-06-26 20:45:56
and of course one measures the power curve for fun
Rotonen
2019-06-26 20:46:00
so when the current drops, it is done?
Fireduck
2019-06-26 20:46:08
yes
Rotonen
2019-06-26 20:46:24
it also has an analog built in display for the doneness
Rotonen
2019-06-26 20:46:39
as in it's pretty obvious it is now hot, crispy, juicy and rather edible
Rotonen
2019-06-26 20:46:39
right
Fireduck
2019-06-26 20:47:39
great fun for the freshmen to marvel at
Rotonen

there are a couple of tricks to it in regards to shaping the plasma channelling (as in sparkthrough prevention), but if one thinks it through a few times and remembers murphy, one is fine
Rotonen
2019-06-26 20:50:12
so maybe do not run off to try it en masse :stuck_out_tongue:
Rotonen

here's a more exterme demo from an old colleague of mine
https://www.youtube.com/watch?v=u6htxWO9GNI YouTube Video: ohminakin paisto motilla (ohm sausage)
Rotonen
2019-06-26 20:53:41
featuring the above mentioned plasma channeling

it even has a finnish wikipedia entry, maybe google translate will manage :stuck_out_tongue:
https://fi.wikipedia.org/wiki/Ohmimakkara Ohmimakkara (myös sähkömiehenmakkara) on temppu, jossa makkaraa kuumennetaan johtamalla 230 V sähkövirtaa pistorasiasta sen läpi. Menetelmä voi olla hengenvaarallinen.
Rotonen
2019-06-26 20:56:43
ah, 230V, I was wondering
Fireduck
2019-06-26 20:56:59
should work just as well with ~100V
Rotonen
2019-06-26 20:57:08
people do that off car batteries as well
Rotonen
2019-06-26 20:57:26
voltage goes distance, amperage heats

@fydel you got time this coming weekend to look at how to have munin not devnull the history beyond one year?
