Back
[00:00:08] <rue_shop3> yup
[00:00:09] <^kat^-afk> and, if the 120vac glitches, even plugged into a ups, the utput will glitch or the brick will reset
[00:00:15] <rue_shop3> its still in case ;)
[00:02:35] <rue_shop3> my load bank can only go up to 5A tho
[00:02:41] <rue_shop3> (5v = 5A)
[00:02:48] * ^kat^-afk nods
[00:03:14] <rue_shop3> would you like to see a sideways load profile with only about 20 points?
[00:03:29] <^kat^-afk> pics of the brick? no
[00:03:43] <rue_shop3> of the load profilers chart
[00:03:46] <rue_shop3> votlage vs current
[00:03:57] <^kat^-afk> yes!
[00:04:09] <^kat^-afk> it's prolly wierd with step oads
[00:04:12] <^kat^-afk> loads
[00:04:15] <rue_shop3> where can I post images easy?
[00:05:08] <rue_shop3> I'll put on my site
[00:06:09] <rue_shop3> http://ruemohr.org/~ircjunk/images/img.png
[00:06:16] <rue_shop3> sorry, its sideways
[00:06:26] <rue_shop3> up is current, across is volts
[00:06:47] <rue_shop3> I can get it to do a few hundred points later
[00:07:01] <rue_shop3> EEK
[00:07:23] <rue_shop3> the supply temp is ok, but not so for my load bank
[00:07:44] <rue_shop3> apparently it dosn't like 60W continious
[00:07:49] <^kat^-afk> it's 100w, of course
[00:08:22] <^kat^-afk> use sections from 208/240v heating coils
[00:08:47] <^kat^-afk> good heat throwing, high current , and compact low resistance
[00:09:07] <rue_shop3> its a fet based digital load current
[00:09:20] <rue_shop3> I have an app I can set the current with and monitor the voltage
[00:09:24] <^kat^-afk> how are you controlling the load current?
[00:09:35] <rue_shop3> or do Ah testing or load profiling
[00:09:46] <^kat^-afk> i mean is it slow or fast steps, or linear slopes?
[00:09:51] <rue_shop3> its an avr, lets me set the current over serial
[00:10:06] <rue_shop3> that chart was done in .25A steps
[00:10:11] <rue_shop3> I can make more
[00:11:07] <^kat^-afk> so 20mv steps for .25 amp changes?
[00:15:06] <rue_shop3> thats a problem
[00:15:16] <rue_shop3> if a HUGE heatsink is overheating at 60W
[00:15:28] <rue_shop3> and I'm maiing a 120W linear poiwer supply
[00:15:38] <rue_shop3> then the little heatsink I have wont come close
[00:16:29] <rue_shop3> at 100/120W, this supply will have to be switching
[00:17:09] <rue_shop3> kat, thats the graph!
[00:17:45] <^kat^-afk> huh?
[00:17:46] <rue_shop3> hmmmm
[00:17:57] <rue_shop3> your saying the steps are 20mv?
[00:18:18] <^kat^-afk> i ate sleepy pils an hr ago, heck if i know
[00:18:27] <Lola8088> I'm saying the steps are 12... and you need them all.
[00:18:29] <rue_shop3> how many watts does an x86 dissipate?
[00:18:37] <rue_shop3> hi
[00:18:47] <Lola8088> Hallo
[00:18:50] <rue_shop3> was the ferry late?
[00:19:16] <rue_shop3> I did hash browns and eggs, home style (burned to pan)
[00:19:33] <^kat^-afk> did yu know sparkfun sells a pi-lookalive but it has two 500Mhz x86 in it?
[00:19:46] <rue_shop3> huh
[00:20:06] <Lola8088> yah... a little. I waited for 20min in Sechelt for him
[00:20:34] <rue_shop3> ferry is in gibsons tho...
[00:20:40] <Lola8088> I'm trying to trick my printer into thinking there is still ink
[00:20:55] <rue_shop3> ah
[00:21:00] <rue_shop3> laser or jet?
[00:21:04] <Lola8088> jet
[00:21:11] <rue_shop3> hmm
[00:21:28] <Lola8088> he took the bus from Gibby to Sech
[00:21:42] <rue_shop3> ah
[00:21:54] <rue_shop3> fine thing to do after asking for a terminal pickup
[00:23:29] <rue_shop3> well, I was gonna bang togethor a quick and ditry power supply, I can see thats not going to work
[00:23:41] <Lola8088> heh eheh eehe a fine thing to do.
[00:23:52] <Lola8088> youtube is full of fun stuff
[00:24:18] <rue_shop3> yup, I was resorting to it from netflix
[00:25:21] <rue_shop3> maybe I should put a thermal sensor on my loadbank
[00:26:00] <^kat^-afk> before it smokes, yeas
[00:26:11] <^kat^-afk> or just asn avr with I and V measurments
[00:26:21] <rue_shop3> its a big heatsink
[00:26:33] <rue_shop3> 60w is a lot of juice
[00:26:53] <rue_shop3> the avr can measure the voltage and current
[00:26:57] <^kat^-afk> k
[00:27:05] <rue_shop3> thats how I do the profile
[00:27:22] <rue_shop3> a program steps the current, measures both and logs to a csv file
[00:27:47] <Lola8088> mmm juice. grape or cranberry... i think i'll live the wild life and mix them.
[00:28:13] <^kat^-afk> then it can calculate the wattage being dumped
[00:28:20] <rue_shop3> it does
[00:28:34] <^kat^-afk> k
[00:28:36] <rue_shop3> Its a 8" x 4" heasink
[00:28:47] <rue_shop3> I thought it'd be good for a few hundred watts
[00:29:00] <rue_shop3> got fins and everything
[00:29:02] <rue_shop3> (no fan)
[00:29:45] <Lola8088> yay! I tricked it. Silly printer. Thought it could make me buy more stuff.
[00:29:52] <rue_shop3> its a dell power supply, I wanted to be sure it would output 5 or 6A without me doing anything to that little grenn wire
[00:30:13] <rue_shop3> Lola8088, will it print if it cant read the chip?
[00:31:10] <Lola8088> it will print only if I do voodoo magic on it
[00:31:12] <rue_shop3> Moon_, STOP CLOSING ICEWEASEL
[00:31:18] <rue_shop3> you loose all my links
[00:32:50] <rue_shop3> Moon_, use kill -9 xxxx then it recovers the tabs
[00:33:03] <rue_shop3> or killall
[00:33:34] <rue_shop3> kat, well, what am I gonna do about an output amp for this quick and dirty supply
[00:33:42] <rue_shop3> should I make a 40Khz pwm?
[00:34:06] <^kat^-afk> an amp? how abount an audio amp?
[00:34:18] <rue_shop3> it cant be linear
[00:34:22] <^kat^-afk> k
[00:34:27] <rue_shop3> as this just pointed out
[00:35:02] <rue_shop3> maybe if I make a 40Khz with a 5th order passive output filter
[00:35:07] <^kat^-afk> i could sworn you were already making a switcher
[00:35:27] <rue_shop3> I decided to detour and make a simple smaller supply
[00:35:38] <rue_shop3> 1 channel, 20V, 5A
[00:36:07] <rue_shop3> and I was gonna go linear, but Its not large enough for the heatsink it would need
[00:36:13] <rue_shop3> my bench isn't big enough
[00:36:26] <^kat^-afk> there's usa shipping for those $1.40 chinese 5amp vari-voltage switchers
[00:38:06] <rue_shop3> that go down to 1.2V
[00:38:14] <^kat^-afk> i dunno
[00:38:17] <rue_shop3> adn burn up at 5A continious
[00:38:20] <rue_shop3> I have two
[00:39:02] <^kat^-afk> 5a = heatsinks with fans, same as the laptop bricks
[00:39:36] <rue_shop3> I need to get foam to make you more digits
[00:40:28] <^kat^-afk> it's not like i m paying you
[00:40:39] <^kat^-afk> read my last email about them?
[00:40:53] <rue_shop3> we can trade for static 1 bit ram chips tho right?
[00:41:01] <rue_shop3> right!?
[00:41:10] <rue_shop3> + chipping?
[00:41:21] <rue_shop3> if I send you chipping...
[00:41:23] <rue_shop3> fees...
[00:41:26] <^kat^-afk> last email was abouot dislayin other numbers
[00:41:33] * ^kat^-afk nods
[00:42:05] <rue_shop3> I can use an eprom to generate 57khz+ pwm
[00:42:07] <rue_shop3> wait
[00:42:11] <rue_shop3> waaaait
[00:42:21] <rue_shop3> whats 200khz/8
[00:42:24] <rue_shop3> er
[00:42:26] <rue_shop3> no
[00:42:35] <rue_shop3> 200khz * 65535 /8
[00:42:40] <rue_shop3> 65536
[00:43:28] <rue_shop3> bah, its till 1.6Thz
[00:43:37] <rue_shop3> what if I use a 16 bit rom
[00:44:12] <rue_shop3> 819Mhz, damnit
[00:44:43] <rue_shop3> cant do 16 bit pwm from an eprom
[00:44:52] <rue_shop3> 10 bit..
[00:45:19] <rue_shop3> I can do 10 bit easy
[00:45:42] <rue_shop3> er, no
[00:45:55] <rue_shop3> maybe just barely at 26Mhz
[00:46:17] <rue_shop3> fast rom
[00:46:32] <rue_shop3> so at 40Khz
[00:46:58] <rue_shop3> not 16 bit
[00:47:29] <rue_shop3> 10 bit, 40Khz, at 5Mhz
[00:47:56] <rue_shop3> kat
[00:48:10] <^kat^-afk> rue
[00:48:21] <rue_shop3> isn't there a circuit to generate a ramp from a series of pulses by accumulating them into a capacitor?
[00:48:40] <^kat^-afk> yeas, seveal
[00:49:23] <rue_shop3> integrator?
[00:49:43] <rue_shop3> hmm
[00:49:55] <rue_shop3> I suppose the rc thing works
[00:50:02] <rue_shop3> if I do this at 40Khz
[00:50:11] <rue_shop3> hmm
[00:50:25] <^kat^-afk> they were stairstep generators, not ramps , if you are googling it
[00:50:40] <rue_shop3> the P channel fet I was trying to use was a problem cause of its input capacitance, it cant switch at 200Khz
[00:50:44] <rue_shop3> yea
[00:51:06] <rue_shop3> if I'm using a digital comparing system anyhow, why not subst the ramp for a staircase?
[00:51:49] <rue_shop3> so, in the quick and dirty, why dont I use a PNP
[00:51:51] <^kat^-afk> because if you sample on the step, you read anything tween the last step and the next one
[00:52:02] <rue_shop3> Von of a pnp, 0.2 0.5?
[00:52:17] <^kat^-afk> .65
[00:52:21] <^kat^-afk> oops
[00:52:26] <rue_shop3> whats a good one for a 40Khz smps...
[00:52:27] <^kat^-afk> i am asleep
[00:52:38] <^kat^-afk> yeas, some pnp are pretty low Von
[00:52:49] <rue_shop3> not 2955
[00:52:55] <rue_shop3> too slow, right?
[00:53:15] <^kat^-afk> i dunno, they don't make the 3055 as slow as they did
[00:53:34] <^kat^-afk> planar epitaxy uses too much die space
[00:54:51] <^kat^-afk> usetobe, the 2n3022/2955 were too slow to use in audo power amps
[00:56:48] <rue_shop3> pnp
[00:57:07] * ^kat^-afk nods
[00:57:09] <rue_shop3> 2sb1225
[00:57:18] <rue_shop3> 2sd1933
[00:57:23] <rue_shop3> 2sb882
[00:57:43] <rue_shop3> I have an smt, marked BGs4A that I suspect is fast
[01:01:14] <rue_shop3> the 882 has a 20Mhz GBP
[01:01:18] <rue_shop3> is that good?
[01:01:28] <^kat^-afk> ok
[01:01:38] <^kat^-afk> i am asleep
[01:01:39] <rue_shop3> oh, its darlington
[01:01:57] <^kat^-afk> then it'sVdrop is at leasdt .9v
[01:02:11] <rue_shop3> VceSat is up t 1.5V
[01:02:37] <rue_shop3> 5A,
[01:02:50] <rue_shop3> 7.5W
[01:03:41] <rue_shop3> makes the supply output peak at about 18V
[01:03:57] <rue_shop3> unless
[01:04:09] <rue_shop3> unless I run a pushpull transformer
[01:04:29] <rue_shop3> I suppose it could be autotransformer
[01:04:45] <rue_shop3> put a few volts boost on iy
[01:05:13] <rue_shop3> 1.4:1
[01:05:18] <rue_shop3> oh, diode losses
[01:05:32] <rue_shop3> 1.5:1
[01:06:18] <rue_shop3> the tl494 wont go to 100%, but it will go to 0%
[01:07:22] <rue_shop3> and it dosn't incorperate a 1.2V fixed ref
[01:19:04] <^kat^-afk> gnites
[01:19:30] <rue_shop3> I should be able to push 150W thru an old computer core
[01:19:41] <rue_shop3> I sleeps too
[01:55:20] <Moon_> SleepS???
[01:55:57] <Moon_> No rest for the electric, and diodes dont grow on trees!
[22:16:24] <^kat^-afk> 74 124 , 324, 327 , 326 , 325 , 324 , 624 , 625 , 626 , 627 , 628 , 629
[22:34:24] <^kat^-afk> looks like they are all $1 each, or more
[22:50:32] <rue_shop3> even from china?
[22:50:58] * ^kat^-afk nods
[22:51:09] <^kat^-afk> some of the 6xx are way more $
[22:51:11] <rue_shop3> wow
[22:51:28] <rue_shop3> dip?
[22:51:35] <^kat^-afk> yeas
[22:52:38] <rue_shop3> 6011, EP or EN?
[22:53:30] <^kat^-afk> huh?
[22:55:31] <rue_shop3> E6011
[22:55:38] * rue_shop3 waits for kat to click
[22:56:18] * rue_shop3 frowns
[22:56:24] * ^kat^-afk blinks nstead
[22:56:28] * rue_shop3 gives "kat" the eye...
[22:56:33] <^kat^-afk> you are talking welding, i was talkng vcos
[22:56:41] <rue_shop3> ah
[22:56:48] <rue_shop3> I was afraid it wasn't really you
[22:56:58] <rue_shop3> those are all vcos!?
[22:57:03] <^kat^-afk> yeas sir
[22:57:07] <rue_shop3> wow
[22:57:23] <rue_shop3> I thought there was like 1 in the seriies
[22:57:29] <rue_shop3> so, EP or EN?
[22:57:45] <^kat^-afk> hot?
[22:57:56] <^kat^-afk> i tend to run the hot +
[22:57:57] <^kat^-afk> er
[22:57:58] <^kat^-afk> -
[22:58:05] <rue_shop3> ...
[22:58:12] <^kat^-afk> stuff all over my mind atm
[22:58:13] <rue_shop3> thats what we all said here
[22:58:30] <rue_shop3> EP, ... errr, EN... orno,... uhhh...
[22:58:34] <^kat^-afk> who else here welds?
[22:58:56] <rue_shop3> here here channel here, or there here?
[22:59:05] <^kat^-afk> negative, the silly idea that the moving electronns will carry the molten steel across the arc better
[22:59:27] <rue_shop3> so electrode negitive
[22:59:35] <rue_shop3> all I remmeber is tig is the other way around
[23:00:33] <rue_shop3> the beatles tell me I need to hide my love away
[23:00:38] <rue_shop3> is this true?
[23:00:51] <^kat^-afk> they also said all yu need is love
[23:00:58] <rue_shop3> hmm
[23:02:29] <rue_shop3> I'm having space problems with the shop
[23:02:56] <^kat^-afk> too much?
[23:03:17] <rue_shop3> not nearly enoguh sapce
[23:03:18] <^kat^-afk> or is the interior space merging with the outside?
[23:03:25] <rue_shop3> yea
[23:04:18] <^kat^-afk> are you using the ceiling space yet?
[23:06:08] * rue_shop3 looks up
[23:06:23] <rue_shop3> there is a smoke detector and two 3d printed objects
[23:06:44] <^kat^-afk> have you considered shelves?
[23:07:16] <rue_shop3> I cant, there is no wall space left
[23:07:42] <^kat^-afk> no, on the ceiling
[23:08:02] <rue_shop3> I think that idea would be impeded by gravity
[23:08:18] <^kat^-afk> fasteners
[23:08:47] <rue_shop3> the normal force of the objects on the shelvs would be low due to the perpendicular nature of the gravitational force
[23:09:03] <rue_shop3> causing them to slide off the 'side'
[23:09:19] <^kat^-afk> nono
[23:09:29] <rue_shop3> :)
[23:09:56] <^kat^-afk> imagine the shelf unit on the floor in the middle of the shop, now lift it up till it's ont he ceiling, bolt it there
[23:10:30] <rue_shop3> hmm
[23:11:24] <rue_shop3> did I tell you about my surprise after I finished the shop and got a non-faxed copy of the engineered roof truses and was able to read the fine print that said "these trusses are not rated to have drywall mounted to them" ?
[23:11:44] <rue_shop3> :S
[23:11:48] <^kat^-afk> ummm, no
[23:12:17] <rue_shop3> I kinda wanted to phone and ask what the difference would be for them to be rated for it
[23:12:25] <^kat^-afk> what are they rated to have attached to them?
[23:12:35] <rue_shop3> nothing
[23:12:44] <rue_shop3> I think they did it for an open cieling
[23:13:03] <^kat^-afk> you should, because you cannot install faced fiberglass without covering it in drywall for fire resistance
[23:13:36] <rue_shop3> its too late now, I dont want to know
[23:14:48] <rue_shop3> I suppose its rated for standard roofing, but not drywall on the bottom
[23:15:13] <rue_shop3> the snow ratings here are stupid, so I'm verry likley ok
[23:17:39] <rue_shop3> oooh I'm falling asleep
[23:18:35] <^kat^-afk> i am not seeing any advertising
[23:18:52] * ^kat^-afk loks behind zlog
