[00:00:11] <zhanx> Kat have you use nails to sense soil moisture?
[00:00:28] <zhanx> I know rue only eats boxed foods
[00:00:29] <rue_shop5> I wish there were a fet the size of a to-92 rated at about 5A
[00:00:30] <katsmeow> no, they tend to rust, even with ac sense current
[00:00:37] <rue_shop5> oh, then again, there are dips...
[00:00:50] <zhanx> What's the best to use then?
[00:00:57] <rue_shop5> all mine are half bridges tho
[00:01:19] <katsmeow> platinum
[00:01:22] <katsmeow> or gold
[00:01:41] <zhanx> If I could do that I wouldn't need a garden
[00:01:53] <zhanx> Coated?
[00:02:06] <katsmeow> plating the gold onto iron would be fine
[00:02:27] <katsmeow> you can get dips that would plate enough on so the nails wouldn't rust
[00:02:45] <zhanx> K
[00:03:12] <zhanx> I mean if I have replace nails 2 a season I would be ok with it
[00:03:18] <katsmeow> look under pcb plating kits
[00:03:41] <katsmeow> the nails will rust, and rust is an insulator
[00:04:36] <zhanx> First link on Google was 350 dollars
[00:04:40] <zhanx> Ouch
[00:04:47] <katsmeow> ouch
[00:05:21] <zhanx> I Google some I got old computer parts etc
[00:05:48] <zhanx> Galvanized?
[00:06:24] <zhanx> Aluminum?
[00:06:25] <katsmeow> up to you, they rust here
[00:06:38] <katsmeow> Al oxide is a super good insulator
[00:07:00] <zhanx> So weekly sanding of them
[00:07:32] <katsmeow> http://www.ebay.com/sch/i.html?_nkw=gold+plating+solution&_frs=1
[00:07:57] <zhanx> I got a bunch of large nails for a buck, guess I should have researched more
[00:08:45] <zhanx> Kat at those prices I can just use emery cloth on them
[00:09:02] <zhanx> And learn to code better
[00:10:08] <katsmeow> 22K Gold Plated Liquid Tube Beads 6mm X 1.5mm (50 Pieces)
[00:10:40] <katsmeow> solder 25 into two strings of gold rod 15cm long , $2.49 free s&h
[00:11:36] <katsmeow> http://www.ebay.com/sch/i.html?_nkw=liquid+gold+plating&_sac=1#seeAllAnchorLink
[00:12:17] <rue_shop5> use carbon electrodes
[00:12:21] <rue_shop5> from pencils
[00:12:29] <rue_shop5> low current, what does resistance matter?
[00:13:05] <katsmeow> clogging the pores may matter
[00:13:10] <zhanx> Well kind of
[00:13:19] <rue_shop5> naaa
[00:13:31] <zhanx> Mechanical pencil lead?
[00:13:35] * katsmeow figures on weighing the pots
[00:13:46] <zhanx> Oh I am gonna have to make a test bed
[00:13:51] <katsmeow> mecahnical is too much polymer
[00:14:00] <rue_shop5> yea 1.2mm mechanical pencil lead
[00:14:11] <zhanx> Raised beds 8×4' is hard to weigh
[00:14:43] <katsmeow> batery core is a lot of graphite, mechanical leads are a lot of polymers to hold them togetehr
[00:14:51] <zhanx> Ok Tuesday I will have to grab supplies and test some things
[00:14:58] <katsmeow> it is hard to weigh?
[00:15:11] <zhanx> Well it's in the ground
[00:15:21] <katsmeow> only if you put it there
[00:15:30] <zhanx> I did
[00:18:32] <rue_shop5> ok I need to write some code
[00:25:56] <katsmeow> stainless steel
[00:26:48] <katsmeow> possibly a couplea spoons
[00:27:01] <zhanx> Butter knives
[00:27:10] <katsmeow> ok
[00:27:50] <katsmeow> lemme know what wife says when yu say you are going to bury the eating utensils
[00:29:58] <katsmeow> ?
[00:30:13] <katsmeow> she cut you off?
[00:31:39] <rue_house> hmm
[00:32:46] <rue_house> hmm, well I'm always welding on a table
[00:32:53] <rue_house> no ladders in the rain for me
[00:33:02] <katsmeow> oh
[00:33:07] <rue_house> usually, if there is any sign of rain, I dont do welding
[00:33:32] <katsmeow> i sweat in summer, things get salty wet and conductive
[00:42:49] <rue_house> [13022031]
[00:43:21] <katsmeow> huh?
[00:43:34] <rue_house> its a step sequencer table
[00:45:51] <rue_house> [9,3,C,6,6,C,3,9]
[00:45:56] <rue_house> is even better
[00:46:35] <rue_house> C is 12?
[00:46:45] <rue_house> D13 E14 F15
[00:46:48] <rue_house> ok
[00:53:00] * katsmeow wavers gnites
[00:54:35] <rue_house> ok I'm only using 4 bits of the 595, so I'm only gonna shift out 4 bits
[00:56:30] <rue_house> unsigned char tableF[] = {9,3,12,6};
[00:56:31] <rue_house> unsigned char tableR[] = {6,12,3,9};
[00:56:31] <rue_house> void next (unsigned char dir) {
[00:56:31] <rue_house> static char status = 0;
[00:56:31] <rue_house>
[00:56:31] <rue_house> if (dir) {
[00:56:33] <rue_house> status = tableF[status];
[00:56:35] <rue_house> } else {
[00:56:37] <rue_house> status = tableR[status];
[00:56:39] <rue_house> }
[00:56:41] <rue_house>
[00:56:43] <rue_house> shiftout(status);
[00:56:46] <rue_house> status &= 3;
[00:56:48] <rue_house>
[00:56:50] <rue_house> }
[00:57:18] <rue_house> its an interrupt, as long as it dosn't get called over itself, it'll all be ok
[22:00:42] <katsmeow> so i was looking at Russian roro boats, carrying trucks and tanks, the hovercraft was interesting, but i think it could be made more interesting
[22:01:47] <katsmeow> and, their Tu-160 and the big turboprop bomber carry the same rotary cruise missile launcher, and some duck snuck it into what looks like a APC
[22:04:11] <katsmeow> they have some interesting small armored tanks, like 1/6 regular size, they might be able to carry a human inside, but it wold be a rough ride, those things are *fast* and scoot like a rabbit
[22:05:15] <katsmeow> one went out and did a donut in the road, and to say it shot mortars doesn't say enough, it was like massively hemoraging them in all directions
[22:05:36] <katsmeow> they gotta be high-loss items, and remote controlled
[22:05:42] <katsmeow> some of the bigger tanks were
[22:06:15] <katsmeow> did you know they practice shooting 1ft targets at a mile out with tanks?
[22:12:53] <zhanx> 6 inches for USA fyi
[22:14:49] <katsmeow> the variety of things thay had to toss explosives was amazing
[22:20:17] <katsmeow> the idea they'd put a horizontal rotary launcher that tossed missiles into the air, was surprising
[22:20:28] <katsmeow> i mean into the top of a truck
[22:20:35] <katsmeow> not into a plane
[22:25:36] <katsmeow> they had several ordinary-looking trucks, hummer sized, that threw missiles 40ft into the air, the missiles have nose rockets, so the rocket is horizontal and aimed at the target before the main engine lites off
[22:26:13] <katsmeow> saves propellant contamination of the area from a main engine lite for a vertical launch
[22:57:43] <katsmeow> rue, you realise that for $16 (free s&h) you can dissipate 6kw in heat? I bet a 6kw resistor costs more
[23:01:07] <katsmeow> err, i mean using TIP107 transistors
[23:01:15] <katsmeow> 100 for $16
[23:10:30] <katsmeow> a stack of 16 in series, paralleled by 6, able to pass 42 amps at 160v
[23:12:10] <katsmeow> 42amps @ 160v = 30amps at 120vac
[23:13:31] <rue_shop5> there you are
[23:13:53] <katsmeow> i are here
[23:15:03] <rue_shop5> I reads your stuff
[23:15:13] <katsmeow> oh!
[23:15:15] <rue_shop5> some people just love to make things go bang
[23:16:06] <rue_shop5> I"m building the stepper driver
[23:16:15] <rue_shop5> its using a t13 and 74ls595
[23:16:25] <rue_shop5> cause I want to use up the t13's on anything I can find a use for
[23:16:33] <katsmeow> oh
[23:16:38] <rue_shop5> then never get them again
[23:17:03] <rue_shop5> unless you tell me a listing their less than 40c ea
[23:17:41] <rue_shop5> it'll have a 1.5A current regulator
[23:18:46] <katsmeow> 17ns dual port rams on ebay again
[23:19:10] <katsmeow> 8kx16 , i think i'll bid this time, see if everyone who wanted them has already bought

[23:33:27] <katsmeow> holydraps
[23:34:03] <katsmeow> the dips cost 50% more than sop :
http://www.ebay.com/sch/i.html?_odkw=tiny13+avr+100&mfe=search&clk_rvr_id=1024343329208&_osacat=0&_from=R40&_trksid=m570.l1313&_nkw=%22attiny13%22+100&_sacat=0
[23:35:14] <rue_shop5> soic I can work with, dip is preffered
[23:36:20] <rue_shop5> hm 77c
[23:36:29] <katsmeow> 272127372980 isn't big enough to buffer a 128x64 page of characters for a 1024x768 display
[23:37:30] <rue_shop5> sorry I dont remember why I was looking for them
[23:38:18] <katsmeow> state machine
[23:38:20] <rue_shop5> I'm gonna exist for about another 1/2 hr
[23:38:42] <rue_shop5> good thing I'm not being paid by the hour to assemble this simple little circuit
[23:39:44] <katsmeow> the ebay page n that TC dual port says it's 30ns, the data sheet says it's 80ns, that's CGA graphics
[23:52:07] <rue_shop5> ok kat
[23:52:23] <rue_shop5> whats the lowest parts count, constant current source
[23:52:24] <rue_shop5> ...
[23:52:40] <rue_shop5> from 12V, with no more than 2V dropout...
[23:52:42] <zhanx> Wish me luck
[23:52:42] <rue_shop5> for
[23:52:55] <rue_shop5> zhanx, break an extra one of his for me
[23:53:05] <zhanx> My tests in 6 hours
[23:53:08] <rue_shop5> 30mA
[23:53:37] <katsmeow> how was today and tanks?
[23:53:46] <rue_shop5> lm317?
[23:54:37] <katsmeow> 780x and ne resistor
[23:54:53] <katsmeow> TL432 and one restsor
[23:55:07] <rue_shop5> lm317 is a 78 1.2
[23:55:09] <rue_shop5> 432
[23:55:11] <rue_shop5> ...
[23:55:58] <katsmeow> 431, sorry
[23:56:24] <katsmeow> yeas, anyhoo, you got the idea
[23:56:32] <rue_shop5> hey I have a bnch of 431
[23:56:54] <rue_shop5> hmm how much can the LM393 sink
[23:57:02] <katsmeow> i dunno
[23:57:37] <katsmeow> being it's a comparator, prolly not much
[23:58:08] <rue_shop5> ugh 16mA
[23:58:14] <katsmeow> 16ma
[23:58:47] <rue_shop5> how log ya think it takes 10mA to charge the gate of an IRFZ44?
[23:59:01] <rue_shop5> prolly 3x longer than 30mA
[23:59:27] <rue_shop5> ... I should have just used a lighbulb...
[23:59:31] <katsmeow> but 10ma is a lot to drive a darlington to switch any gate
