[00:00:25] <rue_shop5> root@blackie2:/zipfiles/programming/c/avr/tiny13/stepper# ohm -p 2 -r 1000000
[00:00:25] <rue_shop5> Wattage is: 2.000000
[00:00:25] <rue_shop5> Current is: 0.001414
[00:00:25] <rue_shop5> Voltage is: 1414.213623
[00:00:25] <rue_shop5> Resistance is : 1000000.000000
[00:01:14] <katsmeow> pretty common in transmitters over 2kw
[00:02:59] <rue_shop5> I found a 74xx07!
[00:03:28] <katsmeow> you should, you bought some n ebay yrs ago!
[00:03:48] <rue_shop5> oh I have yours too
[00:04:02] * katsmeow nods
[00:04:48] <katsmeow> remember any output can be turned into open collector with a 2n7000
[00:06:38] <katsmeow> or a bipolar
[00:08:12] <katsmeow> remember, i contolled the overcurrent OFF of an MJ11016 (the npn,,015?) with a 74F74 and another transistor n it's outut
[00:08:20] <katsmeow> at 48v regulated
[00:08:26] <rue_shop5> damn, I'll have to upgrade the inductor box
[00:09:11] <katsmeow> you have a lathe, you have wire, got thread and 2-part epoxy?
[00:10:51] * katsmeow ponders xhanx making canoes with squared-off sterns, to hang micro outboards on
[00:10:55] <rue_shop5> hu?
[00:11:13] <katsmeow> yo can turn yur own coils (industors)
[00:11:18] <rue_shop5> the box of inductors is overflowing
[00:11:28] <rue_shop5> ferrite core smps inductors
[00:11:29] <rue_shop5> :)
[00:11:38] <katsmeow> oh
[00:12:02] * katsmeow has some of those, like 2x2 and an inch wide
[00:13:38] <katsmeow> trolling motors
[00:16:27] <rue_shop5> I was asked for 50 0.1uF caps by the local maker people
[00:16:37] <rue_shop5> for the faire, so i went thru my boards
[00:16:47] <rue_shop5> I got myself lots of gooies on the way
[00:17:02] <katsmeow> becha they want new one of unknown quality and no proof they work
[00:18:08] <rue_shop5> nope
[00:18:16] <rue_shop5> I checked
[00:23:53] <katsmeow> 1000pcs 0.1uF 100nF 50V 104 Multilayer Monolithic Ceramic Capacitor ±20%
[00:24:13] <rue_house> yea, ceramic is cheap, they need them fast
[00:24:19] <katsmeow> 61 cents per 100
[00:24:27] <rue_house> I know, I know
[00:24:39] <rue_house> I can get 10pcs for 86c 'locally'
[00:24:53] <rue_house> (vancouver, $60-$100 for the trip)
[00:24:59] <katsmeow> 30 cents you saved by mining the pcbs,, i get as peeved thinking of mining those cable boxes
[00:25:19] <rue_house> no, $60.30
[00:25:46] <rue_house> but along the way I got lots of nice inductors, resistors, fets, and chips for me
[00:26:14] <katsmeow> if you spent the $6 on bypass caps (every project needs them), you,a.kwuit .aekrig .asdgzdk nvm
[00:28:04] <rue_house> pyrites call loot bootie right?
[00:28:23] <katsmeow> umm, ok
[00:32:24] <katsmeow> cheap price for trimmers :
http://www.ebay.com/sch/Capacitors/4662/m.html?item=221426509266&ssPageName=STRK%3AMEBIDX%3AIT&_ssn=2012topdeal
[00:33:04] <rue_house> those are all caps./.....
[00:33:17] <katsmeow> lok 1/2 down
[00:33:44] <katsmeow> do a word search in te browser for trimmer
[00:33:54] <rue_house> all thats in ther for me are caps
[00:34:08] <rue_house> bah, I can search for trimmers later
[00:34:30] <rue_house> I'd like to know if you find really good prices on 10 turn in volumes of about 20pcs
[00:35:31] <katsmeow> define "really good"
[00:36:16] <rue_house> http://ruemohr.org/~ircjunk/images/p1080052.jpg
[00:36:22] <rue_house> hmm, I'm not sure
[00:36:40] <rue_house> I'm gonna guess around 5c ea is damn good for 10 turn
[00:37:09] <katsmeow> <cugh>
[00:37:15] <katsmeow> yeas
[00:37:45] <rue_house> I'd expect $1 ea is easy to find, that 50c ea is getting harder
[00:38:05] <rue_house> I'm guessing 30c ea might be the normal bottom
[00:39:12] <katsmeow> http://www.ebay.com/itm/10pcs-Trimmer-Potentiometer-Variable-Resistors-3296W-202-2K-2K-ohm-Hot-Sale-/221259519450 = 37 cents each
[00:40:35] <katsmeow> http://www.ebay.com/sch/m.html?_odkw=&_ssn=2012topdeal&item=221426509266&_osacat=4662&ssPageName=STRK%3AMEBIDX%3AIT&_from=R40&_trksid=p2046732.m570.l1313.TR0.TRC0.H0.Xtrimmer+resistor.TRS0&_nkw=trimmer+resistor&_sacat=12576
[00:43:59] <katsmeow> i did it:
[00:44:00] <katsmeow> 10pcs 5K OHM Trimpot Trimmer Potentiometer Pot Variable Resistor WH06-2 502 BG
[00:44:17] <katsmeow> that's 7.7 cents each
[00:44:27] <katsmeow> oh, not multiturn
[00:45:39] <katsmeow> i did it:
[00:45:42] <katsmeow> 5PCS 50K Ohm Precision 3296w Variable Resistor Trimmer
[00:45:49] <katsmeow> 20 cents each
[00:46:13] <katsmeow> i did it:

[00:46:19] <katsmeow> 10 cents each
[00:48:18] <rue_house> ha looka that
[00:54:52] <rue_house> I'll shop later :)
[00:55:31] <katsmeow> i cannot break below 10 cents each again, so far
[00:56:23] <rue_house> hey, 17c is damn good
[00:56:59] <katsmeow> 17c? the last one was 10 cents
[00:57:13] <katsmeow> here's 9.1 cents :
[00:57:15] <katsmeow> 3296W 50K Ohm Variable Resistor Trimmer Trim Pot Potentiometer Kit 100pcs
[00:57:22] <katsmeow> but, it's 100 ppots
[00:57:41] * katsmeow stops loking
[01:12:39] <rue_house> how about a variety pack?
[01:12:54] <katsmeow> there's ne or two
[01:12:59] <rue_house> I dont know what values I want
[01:13:22] <rue_house> sometiems its cheaper to put togethor a variety pack ones self
[01:16:14] <katsmeow> afk to put the house to bed, brb
[01:20:23] <rue_shop5> I slept earlier
[01:20:32] <rue_shop5> I'm good for god knows how long
[01:22:32] <rue_shop5> I'm getting some energy to work on things tho
[01:22:33] <rue_shop5> this helps
[01:22:52] <katsmeow> bak
[01:22:56] <rue_shop5> plate metal, magnetic but retains nothing, ...tin?
[01:24:11] <katsmeow> "irony" , it's a high iron aluminum
[01:24:18] <rue_shop5> hehe'
[01:24:55] <katsmeow> they call it irony,for real
[01:25:15] <katsmeow> they don't call it "irony aluminum"
[01:25:32] <katsmeow> it's like they call that thing a "blue", not a "blue car"
[01:26:27] <katsmeow> it's now <ding> 1 am
[01:27:30] <rue_shop5> I need to delay synchronous serial data by 4 bits, in a space efficient manner
[01:43:01] <rue_shop5> do you know of a list of ttl chips with func desc?
[01:43:16] <rue_shop5> I need the 8 bit serial in parallel out shift register
[01:43:20] <rue_shop5> 74xx16?
[01:45:45] <rue_shop5> 4
[01:48:47] <katsmeow> 164 165
[01:49:14] <katsmeow> i think yuo have some
[01:49:22] <rue_shop5> I used to prettymuch know them all
[01:49:41] <rue_shop5> yea, I got LOTS of 164/165 for microcontroller stuff
[01:49:58] <rue_shop5> I think I was using the 164 for talking to lcd's over serial
[01:51:36] <rue_shop5> I'm haivng a hell of a time with this stepper driver project
[01:52:10] <rue_shop5> I cant bring myself to just build a current uncontrolled one and ditch them when the good ones arrive from china
[02:00:52] <katsmeow> ok, signing off
[02:00:57] <katsmeow> 1:30 am
[20:52:40] <katsmeow> need motors?
https://www.aucto.com/catalog/nriindustrial/major-liquidation-of-spare-parts-from-former-power-plant/4491
[20:59:48] * rue_house wonders how fast his truck would go with a 1000HP electric motor
[21:00:01] <rue_house> wouldn't go far, broken frame and power cable...
[21:00:30] <katsmeow> they have smaller one, opening bid on the 15hp - 20 hp is $25
[21:00:50] <rue_house> :) + 650 shipping
[21:01:22] <katsmeow> at least
[21:01:22] <katsmeow> best send the solar powered robot
[21:02:10] <rue_house> why did a power plant have so many motors?
[21:02:23] <rue_house> in our power plaants we generally have 1 genorator
[21:02:26] <katsmeow> i think it's a scam
[21:02:57] <katsmeow> they just hold the auction someplace and mention the last place they bought out
[21:03:18] <katsmeow> aluminum wire insulation nicked, corroded :
http://redy-project.org/images/misc/20160517_185801.jpg
[21:03:49] <rue_house> yup
[21:03:52] <rue_house> where from?
[21:04:18] <katsmeow> home se
[21:04:27] <rue_house> your place?
[21:04:29] <katsmeow> no
[21:04:58] <katsmeow> i should check mine, i wonder how i'd do that
[21:05:14] <rue_house> reflectometer
[21:05:26] <rue_house> high freq, do it with the power on
[21:05:27] <rue_house> :)
[21:06:07] <katsmeow> erg
[21:06:31] <rue_house> ------------------------\/\/\/\/\/\/\--------------------...
[21:07:24] * katsmeow knows what one is
[21:13:47] <rue_shop5> I know you know
[21:13:59] <katsmeow> oh
[21:14:28] <rue_shop5> so, what do I do about the 164 I used to delay the serial data 4 bits being rising edge triggered when the data is falling edge triggered....
[21:14:34] <rue_shop5> I have to go to a meeting
[21:14:37] <rue_shop5> biab
[21:14:43] <katsmeow> k
[21:27:15] <katsmeow> http://DesignerThinking.com/images/DSCF7115m.jpg <<== tuhmaterplants
[21:28:21] <katsmeow> http://DesignerThinking.com/images/DSCF7118m.jpg <<== truss #2 on right, ready for grinding on #3 on the left
[21:37:10] <katsmeow> i wonder how often people build things they cannot move into position to use
[23:07:21] <katsmeow> maybe if i put some rice on now, it will be done when i feel like eating it or not
[23:24:51] <rue_house> I'm back
[23:25:31] <rue_house> katsmeow, no upside down tomato plants from the engineer? :)
[23:25:40] <rue_house> NICE trusses
[23:25:55] <rue_house> why are you making trusses?
[23:26:05] <katsmeow> nope, water study and recovery apparatus from the engineer
[23:26:13] <katsmeow> for the plate roller
[23:26:34] <rue_house> oh, for the ingoing sheet?
[23:26:50] <rue_house> isn't that like, a 6 tonne truss?
[23:26:57] <katsmeow> err, or more
[23:27:36] <katsmeow> full load cap of the weld beads and the web pieces is 15 tons before they bend or crack
[23:27:42] * rue_house looks at his 'side table' thats built for about 800lbs and stops asking kat questions
[23:28:04] <katsmeow> the rollers each straddle a truss, makes them strong as hell
[23:28:18] <rue_house> aaah!
[23:28:43] <rue_house> ... do you have a steel floor?
[23:28:48] <katsmeow> principle of removing what isn't working, why buy a 12inch dia roller?
[23:29:15] <katsmeow> the work desk there is steel, and it;s sitting on a 1/4 thick steel deck, yeas
[23:29:35] <rue_house> efficient material storage
[23:30:24] <katsmeow> difficult to explain, the finished product will be real easy to understand
[23:33:32] <katsmeow> in the truss pic, #2 is done on the right, starting #3 on the left
[23:36:28] * rue_house nods
[23:36:45] <katsmeow> couple hrs of grinding to do
[23:37:08] <katsmeow> all the white lines haveto be ground, and all the ticks on the 12 small pieces need to be ground to the end on both sides and the edges and across the end
[23:37:36] <rue_house> does that black scale cause issue?
[23:37:43] <katsmeow> get the mill scale off, and any oils, for a strger weld
[23:38:01] <rue_house> and to think that I just weld thru paint and rust
[23:38:05] <katsmeow> black-brown? i grind it off where i will be welding
[23:38:15] <katsmeow> the grey on the small pieces is the mill scale
[23:38:24] <katsmeow> the black-brown is wire-brushed rust
[23:38:42] <katsmeow> the less crap in the weld bead, the stronger it is
[23:38:55] <katsmeow> i will have tons on this thing, i want it strong, or i am wasting my time
[23:39:05] <rue_house> k
[23:39:59] <rue_house> I have to build my bender too, I'm gonna start after june 12
[23:41:06] <katsmeow> i laid out the pillow blocks for a tiny one, bigegr and stronger than the 3-winch-roller, to roll plate on edge, not just flat
[23:41:13] <rue_house> o, what do I do about the 164 I used to delay the serial data 4 bits being rising edge triggered when the data is falling edge triggered
[23:41:29] <katsmeow> invertor
[23:41:32] <rue_house> data is falling edge triggered
[23:41:44] <rue_house> without adding another 14 pin chip
[23:42:12] <rue_house> I might be able to just work it one bit to the left or right of the delay register
[23:42:22] <katsmeow> transistor grounded emitter
[23:47:52] <rue_house> ARG,t he bits are all int eh wrong order too
[23:48:57] <rue_house> arg, wtf, little endian
[23:52:57] <katsmeow> they prefer the term "native american" , no?
[23:53:17] <rue_house> I dont know why my software didn't work
[23:53:34] <rue_house> aside from all the data is was supposed to be sending being wrong
[23:53:43] <rue_house> but its not sending any data
[23:54:23] <katsmeow> umm, hen doesn't matte rhow it'slatched :-)
