[00:00:57] <katsmeow> [23:19] <katsmeow> rue, think this has some ultrafast photodiodes and leds? http://www.ebay.com/itm/109-PCS-ALPS-MDLM5A025A-FIBER-OPTICS-/331792006017
[00:01:22] <rue_house> mailbox does not exist?!
[00:01:47] * katsmeow points at Tom
[00:02:03] <katsmeow> i spose he and zhanx don't want any
[00:02:15] <katsmeow> sharing doesn't work,, damnit
[00:03:33] <rue_house> how did I know about the optos?
[00:03:48] <rue_house> supposed to have
[00:04:20] <katsmeow> those don;t look like fiber connectrs
[00:04:42] <rue_house> is there a conversation going on with me that I dont know about>?
[00:04:57] <rue_house> cause its leaving one of me really confused
[00:05:26] <katsmeow> only 3 conversations that i know of, with sidebands
[00:05:37] <katsmeow> 4, actually
[00:05:58] <rue_house> no, this cant be, I'm only part of half a conversation and I dont even know what its about!!!!
[00:06:00] <katsmeow> optos, zhanx's new internet, Tom's email, capacitors
[00:06:27] <rue_house> capacitors with me!?
[00:06:37] <rue_house> I know something I dont know about capacitors
[00:06:44] <rue_house> I was reading about the brain today
[00:06:55] <rue_house> I have another fake tooth cap
[00:06:57] <rue_house> a temp for now
[00:06:59] <rue_house> :/
[00:07:18] <katsmeow> did you know that was happening?!
[00:14:54] <katsmeow> 3000 PCS SANYO CE2CR47MCYALC CAPACITORS
[00:15:15] <rue_house> is that different than the other ones you were telling me about?
[00:15:22] <katsmeow> 4.7u @ 160v or 200v, i forget
[00:15:25] <katsmeow> yeas
[00:15:26] <rue_house> I'm really good for caps right now
[00:15:40] <katsmeow> just mind boggling how cheap
[00:16:03] <rue_house> please dont stop telling me about what you find tho
[00:37:02] <katsmeow> no forking wonder i cannot find that part, it's ALSO named wrong, they listed it as ECEVIVG470P but it's a ECEV1VG470P !!!
[00:48:31] <katsmeow> found the datasheet, Pnasonic dropped the line, the 47u @ 35v is alowesd only 98ma ripple current
[00:48:41] <katsmeow> how can that be usefull??
[00:49:23] <katsmeow> i dunno how only 98ma of ripple can be a useful item, and i think Panasonic agrrees , since they quit making it
[21:24:04] <rue_shop3> kat!
[21:24:06] <rue_shop3> there ya are
[21:24:16] <katsmeow> where !?!
[21:24:23] * katsmeow looks aroud frantically
[21:24:24] <rue_shop3> I got some 130009 for the power supplies
[21:24:31] <rue_shop3> er, 13009
[21:24:33] <katsmeow> too many zeros
[21:24:35] <katsmeow> yeas
[21:24:40] <rue_shop3> they arrived today
[21:24:47] <rue_shop3> and so did the 74hc4060
[21:24:50] <rue_shop3> :))))
[21:24:59] <rue_shop3> must be the only thing that went well today
[21:26:04] <katsmeow> i sent you email, i think that went well too
[21:27:55] <rue_shop3> cant remmeber how I know what you said to me
[21:28:10] <rue_shop3> I remember 98ma
[21:28:48] <katsmeow> huh?
[21:29:28] <rue_shop3> I'm starting to understand the brain more
[21:30:31] <katsmeow> i sent you email for you to see if my math is wrong on a capacitor as a UPS
[21:30:59] * katsmeow reaches for th antacid
[21:32:32] <rue_shop3> oh I might not ahve checked it yet
[21:36:05] * katsmeow reponders a stack of caps charged to 27v, and irf1405 and irf4905 to toggle which point of the stack the line is connected to
[21:37:06] <rue_shop3> 270?
[21:37:06] <katsmeow> 6 layers of caps charged to 27v = 160v, the peak of 120vac sine wave
[21:37:14] <rue_shop3> ah
[21:37:15] <rue_shop3> yes
[21:37:25] <rue_shop3> may I expand the idea?
[21:37:39] <katsmeow> prolly
[21:38:34] <rue_shop3> 256(random number) of capacitors in a row, each with a transistor for charging and discharging
[21:38:43] <katsmeow> but i thought the 47,000ufd charged to 400v was a good idea too
[21:38:47] <rue_shop3> one sequencer goes thru charging the caps
[21:39:00] <rue_shop3> another sequencer goes thru discharging them, but not completely
[21:39:09] <rue_shop3> nor does the charger charge them completely
[21:39:21] <rue_shop3> the two sequencers are 120Hz apart
[21:39:23] <katsmeow> 256 is too much cycling, remember it takes amps to charge fet gates when done so fast
[21:39:42] <rue_shop3> ok, your not seeing it, no worries
[21:40:13] <rue_shop3> there is a harmonic that leaves the output with varrying votlages between 0 and full charge
[21:40:17] <katsmeow> it's ok, you are not addressing my concerns eaithe
[21:40:22] <rue_shop3> the input always sees a constant charge rate
[21:41:59] <rue_shop3> cleaning shop :)
[21:43:09] * katsmeow nods :-/
[21:44:05] <rue_shop3> there is a magic number of capacitors of a particular size to make it works, I dont remember what it was
[21:45:08] <katsmeow> i was just aiming for a ups that never died and recharged in seconds
[21:45:50] <rue_shop3> I was going for a DC to AC converter with no loss
[22:08:43] <rue_shop3> what did the transistor say to the load?
[22:08:50] <__m00N__> What
[22:09:24] <rue_shop3> resistance is futile
[22:09:36] <__m00N__> Thinking..
[22:10:19] <__m00N__> :( I dont get it
[22:13:13] <rue_shop3> so kat
[22:13:33] <rue_shop3> one part of the left side of the brain does all the language/speech
[22:13:49] <katsmeow> ok
[22:13:52] <rue_shop3> so whats done on the corresponding other side of the brain?
[22:13:58] <katsmeow> less
[22:14:58] <rue_shop3> its what I have to work out next
[22:15:01] <rue_shop3> I think its planning
[22:33:02] <katsmeow> .
[22:48:04] <rue_shop3> still here
[22:48:08] <rue_shop3> I put the wheels away
[22:48:17] <rue_shop3> need to do something with these batteries
[22:49:23] <__M00N__> Bateries??????????
[22:49:50] <katsmeow> fried?
[22:49:56] <rue_shop3> all the dead ones we tried to start the truck with
[22:50:01] <__M00N__> ha
[22:50:13] <__M00N__> well
[22:50:33] <katsmeow> you start the trucks with dead batteries? how??
[22:50:34] <rue_shop3> all need to be charged
[22:50:36] <__M00N__> im not there to do the "unemployed weekday drop off"
[22:50:57] <rue_shop3> they jst all need to be charged
[22:51:11] <rue_shop3> right now they are just in the way
[22:51:15] <__M00N__> put em all in series and put 120 across EM
[22:51:21] * katsmeow points to them sternly and charges them with being dead
[22:51:33] <__M00N__> :P
[22:51:56] <rue_shop3> :)
[22:52:23] <rue_shop3> so right now, the shop is being taken over by gears, wire and pipe fittings
[22:52:55] <__M00N__> BOXES OF DOOM
[22:53:03] <katsmeow> finally making that traveling bridge crane, eh?
[22:54:13] <rue_shop3> togethro they reduce the shop floor space by 33%ish
[22:55:03] <rue_shop3> I'm gonna move the transformers out to the deck, where they are on their way to scrap metal
[22:55:08] <katsmeow> but nothing is using the shot celing space
[22:55:41] <__M00N__> I wana pick threw em if thier still there
[22:56:34] <katsmeow> 7:9 error rate
[22:57:03] <Tom_itx> this cold is whippin my arse
[22:57:40] <katsmeow> yea, but are you enjoying it?
[22:57:51] <Tom_itx> definitely not
[22:57:55] <__M00N__> HA
[23:23:36] <katsmeow> comparing same-sized cans, one of sliced string beans, one of salmon, one of some other fish, the beans are 40 calories, the two fish are 600 calories each
[23:29:56] <katsmeow> SpaceX rocket fails attempted barge landing for fourth time
[23:41:14] <rue_shop3> ok I'v eaten
[23:42:09] <rue_shop3> so they can land, just not anywhere specifically
[23:45:14] <katsmeow> i dunno how much that rocket weighs, but i bet suddenly getting a 100ton load of rocket dropped on any such normal barge will make it move and drop the rocket
[23:46:38] <katsmeow> and if the rocket is moving sideways, it first sees the ocean and thinks it's 20ft abovelanding, then passes over the barge and discovers it's landing as if it still has 20ft to go, WHAMMO
[23:52:17] <rue_shop3> I dont know what to set up for robotics tommorow
[23:54:19] <__M00N__> More Bottle Rockets
[23:54:38] <__M00N__> or some biz to strap thos elastic band gear "pully" boxes on
[23:54:51] <rue_shop3> hmm
[23:54:59] <rue_shop3> it might be pouring rain
[23:55:26] <katsmeow> how a gyroscope may keep a robot on it's feet
[23:55:48] <rue_shop3> we dont ahve verry advaned students rigth now
[23:56:17] <__M00N__> Just little Gaffers
