[00:00:38] <katsmeow> 100 PCS STM LM358AN INTEGRATED CIRCUITS
[00:01:12] <rue_house> I'm trying to find a good deal on 2SD1207, about $8 for 100pcs
[00:01:19] <rue_house> cant get even close
[00:01:30] <katsmeow> 182 PCS SPANSION S29GL256S90TFI020 FLASH EEPROMS NEW
[00:01:48] <katsmeow> $8 for 100pcs of transistor?
[00:02:08] <rue_house> http://www.aliexpress.com/item/100pcs-2SB892-B892-TO-92L/32488238824.html
[00:02:14] <rue_house> the PNP is $5/100
[00:02:57] <rue_house> for 1A H bridges
[00:03:04] <rue_house> without having to drive them fancy
[00:04:18] <katsmeow> 1A in a TO-92 isn't going to be easy
[00:04:59] <rue_house> TO-126 if I can find the gain
[00:05:11] <rue_house> DB139/140 are a bit low
[00:06:55] <katsmeow> what's a 2n7000 good for? 1/2 amp?
[00:07:12] <rue_house> less
[00:07:25] <rue_house> 100 / 200ma iirc
[00:08:56] <rue_house> I suspect the BD140 from china are gains of about 40
[00:09:08] <rue_house> if I can drive 10mA
[00:09:32] <rue_house> then I'm still better off with a pn2222
[00:15:59] <rue_house> !?
[00:16:12] <rue_house> there is a 2222 variant thats rated for an amp
[00:16:34] <katsmeow> in a super to-92 case
[00:21:47] <rue_house> now kat, its not about how small it is, its about how you use it
[00:22:10] <rue_house> I'm guessing its got a low voltage drop
[00:22:20] <rue_house> 2SD09650RA
[00:22:27] <rue_house> to-92, 5A
[00:22:47] <katsmeow> there' 2 different to-92 cases, rue
[00:22:56] <rue_house> tall and normal?
[00:23:00] <katsmeow> yeas
[00:23:07] <rue_house> and normal with tab
[00:23:19] <katsmeow> technically, that's not to-92
[00:23:24] <rue_house> ah
[00:26:16] <katsmeow> i can add a diode to a transistor to protect it from reverse bias, why can't i add something to it to protect from over-high forward bias??
[00:27:20] <katsmeow> it's a TIP107, why can't i put 200v on it??
[00:27:45] <rue_house> zener and something?
[00:28:37] <katsmeow> thent he zener will be dissipating 6amps at 100v
[00:29:17] <rue_house> aha
[00:29:21] <rue_house> a seller made a mistake
[00:29:34] <rue_house> listed BD435 for cheap as PNP
[00:29:49] <katsmeow> or, he typoed the part number? get a pic
[00:30:18] <rue_house> pic shows 435
[00:33:00] <rue_house> doyou know the continious drive current of a LM386?
[00:35:15] <katsmeow> i will in a minute
[00:35:28] <katsmeow> prolly 10ma
[00:36:54] <katsmeow> it has no output emitter resistors!
[00:38:42] <katsmeow> looks like 1/2 amp
[00:38:50] <katsmeow> lil less
[00:39:02] <katsmeow> the higher the voltage the more it is gonna overheat
[00:39:12] <rue_house> hmm, transistor driver?
[00:40:09] <katsmeow> i spose, didn't you et some to drive mosfet gates?
[00:40:35] <rue_house> I'm wandering thru options
[00:40:50] <rue_house> I got lots of 386
[00:41:19] <rue_house> the 555 is a better driver, but there is a trick to using it I'm not sure of yet
[00:41:50] <katsmeow> why are you having problems driving bipolars now?
[00:42:27] <rue_house> I'm trying to solve a problem that dosn't exist yet
[00:44:20] <katsmeow> technically, a TL082 can drive a TIP107 to what passes for saturation in a darlington
[00:46:12] <rue_house> like to stay smaller than a 220
[00:46:43] <rue_house> I can just use mosfets if I go to 220
[00:47:09] <rue_house> but oof, $9 for 100pcs, thats cheap
[00:47:55] <katsmeow> $9 per 100 for which?
[00:48:06] <rue_house> TIP107
[00:48:23] <rue_house> http://www.aliexpress.com/item/Darlington-tube-TIP102-TIP107-into-the-TO-220-original-new-chip-JXDD2/32694648522.html
[00:48:37] <katsmeow> arrg, i just paid $15 for that
[00:48:48] <rue_house> you prolyl got a better product
[00:50:31] <katsmeow> are they selling 107 or 102 ?
[00:51:02] <rue_house> oh, thats a caution isn't it?
[00:51:13] <rue_house> aha, 2SD882 is cheap
[00:52:07] <rue_house> gain is all better than everyone so far
[01:01:44] * katsmeow wavers gnites
[22:03:04] <katsmeow> <ding> rue has email </ding>
[22:03:41] <Tom_itx> 'You've got mail'
[22:04:44] <katsmeow> 48vdc psu 8amps $21
[22:04:54] <Tom_itx> nice
[22:05:18] <katsmeow> i don't have one, but rue has that 48v battery in one of his upses
[22:06:00] <Tom_itx> oh
[22:06:51] <katsmeow> so, i was thinking all wrongly again
[22:07:21] <Tom_itx> 48v is a good number for steppers
[22:08:47] <katsmeow> the other item was 2200ufd 50v caps, 10 for $3.15 + $2.39 s&h , making a nice 22,000ufd for under $6
[22:11:11] <katsmeow> free s&h on 2nd order and up
[22:11:32] <katsmeow> making the 2nd 22,000 ufd only $3.15
[22:12:27] <katsmeow> the brand name is Rukycon, written stylised to resemble Rubycon
[22:35:47] <Tom_itx> tricky folks
[22:52:55] * katsmeow stretches
[22:53:25] * Tom_itx is tired
[22:53:42] <katsmeow> i am surprised Tom is here at all
[22:54:06] <katsmeow> wanna see something odd?
[22:54:06] <Tom_itx> waiting on a drive clone
[22:54:09] <Tom_itx> sure
[22:54:11] <katsmeow> https://duckduckgo-owned-server.yahoo.net/d.js?q=OWL%20class%20%22Location%22&l=wt-wt&p=1&s=0&a=ffsb&ct=US&ss_mkt=us&vqd=0.83562015341372485&sp=1&yhs=1%27
[22:54:14] <Tom_itx> then i'm gonna sleep
[22:54:52] <Tom_itx> what is it
[22:55:25] <katsmeow> a side door into the DDG search engine
[22:55:38] <Tom_itx> oh
[22:57:39] <Tom_itx> huh, doesn't mean much to me but looks like something that shouldn't be visible
[22:58:26] <katsmeow> it is a listing of urls, from search results
[22:58:37] <Tom_itx> oh
[22:58:47] <katsmeow> but yea, they don't mean for the average mortals to see it
[22:59:12] <Tom_itx> what port did you get in on ?
[23:00:01] <katsmeow> 80
[23:00:09] <katsmeow> well, 443
[23:00:26] <Tom_itx> clone is done
[23:00:49] <Tom_itx> now to figure out why the 32bit 7 doesn't see my video the same as the 64bit ver
[23:07:58] <rue_house> toto rosanna

[23:09:38] <rue_house> I beleive you tom
[23:10:06] <Tom_itx> not all of those
[23:10:18] <katsmeow> i never heard of "i believe you Tom"
[23:10:20] <rue_shop3> same album tom
[23:10:24] <rue_shop3> er tape
[23:10:49] <Tom_itx> what did prism put out?
[23:10:54] <Tom_itx> i recall having that one
[23:13:47] * katsmeow looks back and forth, feeling let out as ever
[23:14:10] <rue_shop3> dunno
[23:14:12] <Tom_itx> major tom
[23:14:33] <Tom_itx> kats n the cradle
[23:15:50] <katsmeow> i is not
[23:17:14] <Tom_itx> this damn video card
[23:17:31] <Tom_itx> works fine in 64 but not in 32
[23:17:34] <Tom_itx> wrong modes
[23:19:01] <Tom_itx> why would the OS bits affect the video card output?
[23:19:31] <Tom_itx> i can get 1400 x 1050 but not 1080
[23:19:52] <Tom_itx> 1920 x 1080
[23:20:13] <katsmeow> that's a gawdaweful amount of bits per frame
[23:20:34] <Tom_itx> i must need to find a driver for it
[23:20:42] <Tom_itx> i use it for cad
