<eintopf> chernobyl :/
<DocScrutinizer05> revival
<DocScrutinizer05> fires could re-suspend radiating material. Nobody knows exactly how much would get suspended into atmosphere when contaminated areas burn down
<DocScrutinizer05> http://netc.com/ is vastly useless
<viric> I didn't think about resuspending.
<whitequark> yeah, that's not nice for sure
<viric> I have a chemical engineer from Kiev as neighbour; he moved out the country immediately after the melt.
<viric> I don't know how well goes the reconstruction of the 2nd covering wall
<viric> it was scheduled for ~2013 or so, isn't it?
<viric> the last I heard was that there was a shortage of money for that
<viric> ukraine also used that to preassure foreigners for providing a money supply
<viric> EU specially
<viric> it's like a man with bombs around the body, asking for money in front of you.
<whitequark> smart
<viric> it happened that most of incomming money was used for the world cup, back then
<viric> well, not necessarily "incoming".

<viric> DocScrutinizer05: 2017 was the original plan?
<DocScrutinizer05> nope, I've read in one article today that some responsible international dude explained that due to last year's delays the date shifted from 2016 to 2017 - iirc
<DocScrutinizer05> >>The project had been scheduled for completion by the end of this year but the EBRD said last year technical problems would delay it until late 2017.<< http://news.yahoo.com/forest-fire-near-ukraine-chernobyl-nuclear-officials-171649579.html
<wpwrak> viric: (bomb belt and money) at least it wasn't spent on adding more bombs :)
<eintopf> I don't understand the current situation in chernobyl. When the supergau(don't know if this is also the english word) occurs then it was UDSSR. Now who take care about chernobyl russia or ukraine?
<eintopf> maybe nobody
<viric> there is a common funding between EU, Russia, Ukranie, ...
<viric> but Ukranie is the main executor of tasks.
<viric> for what I understood
<eintopf> ah, ok.
<eintopf> but they have bigger problems now
<viric> The russian tsar

<whitequark> DocScrutinizer05: remember the ATX 3.3V regulator madness?
<whitequark> we figured out how it works
<whitequark> two words: "magnetic amplifier"
<whitequark> +3.3V rail is set by a so-called magnetic amplifier (magamp) comprised of saturable inductor L8, bipolar transistor Q15, diode D14, and control circuitry. Initial inductance of L8 is much higher than L9, so at the beginning of each switching cycle L8 prevents current from flowing through D28. Then L8 rapidly saturates and D28 begin conducting. The blocking time depends on the reset
<whitequark> currnt through Qh15 and D14, which in turn is set by shunt regulator M9.
<whitequark> bizarre shit
<DocScrutinizer05> waitwaitwait, this is a completely different schematics
<whitequark> yes, it's a bit different
<whitequark> but same principle
<whitequark> original one is at http://www.pavouk.org/hw/atxps.png if you lost the link
<DocScrutinizer05> ta
<whitequark> it seems to do the saturating inductor trick only on one half-wave though
<whitequark> which is weird
<DocScrutinizer05> yes
<DocScrutinizer05> I said that back when
<whitequark> oh
<whitequark> I didn't get it then
<DocScrutinizer05> it's weird since the drover is symmetrical
<DocScrutinizer05> driver*
<whitequark> yes
<DocScrutinizer05> weird "transductor" thing is the right one of the upper 3 coils of T2 in http://www.pavouk.org/hw/atxps.png
<whitequark> yeah
<whitequark> it uses positive feedback through T2 to avoid having to drive Q1/Q2 with large base current
<whitequark> TL494 opens Q1/Q2 a bit through T2, which start to conduct and thus raise the primary current, which opens them even more
<whitequark> and at some point TL494 decides to stop the cycle based on feedback and shorts T2
