[00:04:07] <Jymmm> any19979269: oh man, I feel for you there.
[00:12:08] <Moon_> .
[00:17:50] <Moon_> RUE needs run a server
[00:20:52] <rue_house> ah
[00:21:12] <rue_house> kat, isn't it a metal roof?
[00:23:19] <any19979269> 50-50
[00:24:13] <any19979269> the flat part is latex over tar, because i could not get any rubber roofing when i installed it, everyone lauhed at me and said they don't put rubber membranes on roofs
[00:24:40] <any19979269> but the entire western tin roof is also shedding rust, and won't last 5 years
[00:28:58] <Jymmm> what is "western tin"? The corrigated stuff?
[00:31:26] * any19979269 looks blankly
[00:31:49] <any19979269> western is a direction or location, tin is a type of metal roof
[00:31:58] <any19979269> the house has 4 sides
[00:32:02] <any19979269> one side is western
[00:32:07] <any19979269> one is sounthern
[00:32:15] <any19979269> it has tin too
[00:32:24] * any19979269 repeats for the other 2 sides
[00:32:56] <rue_house> I think I actually have a cold
[00:33:15] <any19979269> then you shold put a warm under the covers with you
[00:33:50] <rue_house> I have a neo citron
[00:34:00] <rue_house> dosn't look like its verry neo tho
[00:34:20] <Jymmm> Western, as in cowboys and such. "western tin" as in what they use to decorate the interior of "texas bbq" places... http://1.bp.blogspot.com/-ifjKGZzta7I/UBSrrsL8pOI/AAAAAAAAA4Y/FWSSoHr6xKg/s1600/armadillo+016.jpg
[00:34:23] <any19979269> i tell you guys , and no one believes me, a 2x2ft hutch over the foot of the bed, and 2ft off one side, with a ,, oh, nvm, you wn't care about it's benefits anyhow
[00:34:42] <rue_house> sound slike a good idea
[00:35:39] <rue_house> I screwed up the pulse direction logic on the power supply
[00:35:47] <rue_house> I kept changing drivers and got mixed up
[00:36:00] <rue_house> some of my drivers were active high and the rest active low
[00:36:12] * rue_house ponders hi-z as the active state...
[00:36:22] <rue_house> anyhow, I got mixed up
[00:36:53] <rue_house> the control circuit ended up nice and compact
[00:38:28] <any19979269> http://DesignerThinking.com/images/IMG_0592.JPG <<== you can see some of the roof rusting 15 yrs ago, it's really bad now
[00:38:49] <any19979269> cannot fix it because that makes the neighbor's dogs bark, and they';ll put me in jail
[00:39:15] <rue_house> I'v seen roofing like that last a long time, thin paint?
[00:39:34] <any19979269> cannot get out onto it without making noise
[00:39:56] <rue_house> it looks like scaffold access only
[00:40:02] <any19979269> hell, i dropped the rake today while their dog was inside their trailer, and the dog started barking fiercely
[00:40:20] <any19979269> rue, ladder bracket hooked over the peak
[00:40:39] <any19979269> the over-the-peak is 6ft drop stra8 down to flat deck
[00:40:53] <Jymmm> goto jail? for making noise?
[00:41:22] <rue_house> the DA is in kahoots with her drug-growing neighbours
[00:41:35] <any19979269> for making the dogs bark, it's felony mental cruelty to an animal
[00:41:53] <rue_house> they are using her property to grow illegal drugs and keeping her contained and fully sued to hide it
[00:42:05] <Jymmm> Puppy Prozac?
[00:42:26] <any19979269> they won't sedate their precious harmless gods, don't be silly
[00:42:53] <Jymmm> hey, if you tossed out the trash, and the dog got into it...
[00:43:00] <rue_house> kat, the new pwm genorator circuit works really nicely
[00:43:25] <any19979269> they said fencing them to stay on their 3 acres wold be cruel, better to put me away in a 6x10 cage for the rest of my life than restrict the dogs any
[00:43:30] <rue_house> kat, you dont get otrnadoes on the mountian do you?
[00:43:55] <any19979269> cannot take the trash out either, that also makes the gods bark, i have not taken the trash out n over 10 years
[00:44:01] <any19979269> rue, yeas
[00:44:34] <rue_house> https://cdn.hackaday.io/images/4239351453889382699.jpg
[00:44:38] <rue_house> did you see my pwm gen?
[00:44:48] <any19979269> no
[00:45:07] <rue_house> it uses a 4060 to make a square wave thats put thru a losspass and into a comparitor
[00:45:36] <any19979269> it did that 4 days ago, didn't it?
[00:45:37] <rue_house> if you dont stretch the votlage too much, the triangle is almost linear
[00:45:52] <rue_house> I came up with it a while ago, I'm still thrilled
[00:46:06] <rue_house> its like the ultimate merge of digital and analog
[00:46:18] <any19979269> so you are happy i psuehd you into it?
[00:46:37] <rue_house> :)
[00:46:59] <rue_house> I'm wondering if a 555 would be stable enough for one
[00:47:16] <rue_house> I went to a crystal to be SURE the osc was stable
[00:47:29] <rue_house> but of course it has to be divuided down
[00:49:33] <any19979269> yo had so much good luck with the 555 before :-/
[00:50:21] <rue_house> heh, with a .06% error margin
[00:50:35] <rue_house> as long as I was exactly on spec, it was ok
[00:50:51] <rue_house> so much as .03V the wrong way on the drive signal and it went to hell
[00:50:55] <rue_house> which I dont understand
[00:51:03] <any19979269> i still say you cannot force off that 2SD401
[00:51:08] <any19979269> and you should
[00:51:41] <rue_house> I took and tried togethor 2 and 6, put a digital wave inot it, and it wouldn't trip the output properly
[00:51:52] <rue_house> kat, I switched to a fet circuit in the end
[00:52:09] <rue_house> the bipolars were dropping way too much votlage
[00:52:11] <any19979269> so again, this schematic is not worth loking at or discussing
[00:52:25] <rue_house> I found a fet driver that worked pretty good
[00:52:39] <rue_house> its the 4060/lm393 part thats awesome
[01:24:24] * any19979269 awaits the correct schematic
[01:24:48] <rue_bed> the first part is the same
[01:25:03] <rue_bed> all I did was change the transistor driver
[01:55:55] <Jymmm> rue_house: What is this fancy schmancy PS for?
[01:59:33] <any19979269> because a linear regulator wold overheat the shop
[02:07:49] <Jymmm> FREE HEAT!!!
[02:09:00] <any19979269> IN SUMMER EVEN!!
[08:56:50] <rue_house> Jymmm, its just a power amp for the power supply the regulation is done by another board
[08:57:23] <Jymmm> rue_house: ah, ok.
[08:57:55] <rue_house> https://hackaday.io/project/296-bench-power-supply
[08:59:30] <Jymmm> rue_house: FWIW, Older onkyo systems (audio only, no video) had EXCELLENT and very quite PS's.
[09:00:24] <rue_house> that were not variable from 0 to 30V at 0-5A
[09:00:55] <Jymmm> rue_house: Mine ghetto bench ps http://www.eevblog.com/forum/reviews/b3603-dcdc-buck-converter-mini-review-and-how-the-set-key-could-be-fatal/
[09:01:17] <Jymmm> attached to an old laptop ps
[09:03:14] <Jymmm> there is a 5A variation of that as well
[09:04:52] <rue_house> I'd bet its not good to the full 5A range, those small converters come with a footnote saying they are only good for 24W or so
[09:09:38] <Jymmm> another 400W http://www.ebay.com/itm/400W-DC-DC-Boost-Converter-Step-up-Module-Power-Supply-for-DIY-Vehicle/321785571056
[09:13:08] <rue_house> that board probably dosn't do well, or dosn't go, below 1.2V output
[09:13:39] <Jymmm> That one is boost, so no =)
[09:14:37] <Jymmm> This one says it does http://www.ebay.com/itm/38V-6A-DC-DC-Boost-and-Buck-Step-up-Step-down-Module-Constant-Current-Voltage/321785591278
[09:15:38] <rue_house> there is a thing called the "chinese amp" its not the same as a north-american amp
[09:15:41] <rue_house> its smaller
[09:16:17] <Jymmm> Thats why I said "it SAYS..." =)
[09:16:37] <rue_house> :)
[09:17:14] <Jymmm> My B3603 does pretty well though, I like it.
[09:17:28] <rue_house> I think 1 NA amp =~ 0.8 chineese amps
[09:17:57] <rue_house> what I need to find is just a 30V, 5A pwm driver
[09:18:10] <rue_house> the regulators dont work because of their 1.2V internal references
[09:18:19] <Jymmm> Rule of thumb = Derate china stated claims by 50%
[09:18:39] <Jymmm> lumens, mAh, watts, etc
[09:24:11] <rue_house> I'm staying home today, I'd apparently picked up an evil cold
[09:24:29] <rue_house> i cand bweeeeth
[09:41:16] <Jymmm> Got air compressor? lol
[12:51:41] <sparverius> #garf hashtag garf #hashtag #garfield #theGarf #mondays
[14:25:25] <rue_house> where do all these wierd people come form?
[14:26:28] <Jymmm> rue_house: #ThePlanetGoofy ?
[23:56:05] <rue_house> hmmm
[23:56:19] * katsmeow hmms along
[23:56:29] <rue_house> I wonder what day of my life this is...
[23:56:39] <katsmeow> the most recent one
[23:58:57] <rue_house> leap years since...
