14:34 any35740771 ok, i got 60ft of 2/0 fine copper welding cable in fine condition (30ft looks like it's never been used), 30ft of 8-4 SOOW, and 30ft of 6-4 SOOW and 4 6ft lengths of 2/0 , and a 6ft power cord
14:34 any35740771 for $47
14:36 zhanx nice
14:40 any35740771 yeas, either of the 4-conductor would have cost that much, and the 2/0 would have been many times that $
14:41 any35740771 now i won't need to move the arc welder to go from outside to inside from bow to stern on the boat, or big trailer
14:41 zhanx no that is a long reach now
14:41 anx is playing with his beaglebone b
14:42 any35740771 i figure i can run the 2/0 from the welder, to a 6ft length of 1/0 to the rod holder
14:42 any35740771 err,, smaller than 1/0
14:43 any35740771 i have 20ft of 1/0 as gnd wire now
14:44 any35740771 #1 or #2 as pigtail to the rod, i forget which, it gets a bit warm if i have it cranked and running long beads steadily
14:44 any35740771 but it give me easy movement

17:14 any86362815 Updated 7 sec ago Partly Cloudy 96.6 �F Feels Like 111 �F
17:14 any86362815 so much for "copy and plain text", it was including formatting that went to the server, not to the channel
17:16 any86362815 erg
17:38 rue_school kat!
17:38 rue_school dont see ya much anymore
17:38 any86362815 i don't see much talking in here any more
17:38 any86362815 and i been keeping odd hours
17:39 rue_school yea, Its been distracting (new temporary life)
17:39 rue_school I have to go shopping, I'd take a nap if there weren't a pressure washer on the other side of the wall
17:40 any86362815 i aided the recycling for goodies again
17:40 rue_school I just found a bug in my 2d library that means all my old sofware is compensating for a 45 degree error
17:40 any86362815 really? i have a pressure washier upstairs and it isn't keeping me awake
17:40 rue_school ah yes, what treasures you find?
17:40 rue_school this one is outside, and its running
17:40 rue_school did I mention its gas driven?
17:41 any86362815 ok, i got 60ft of 2/0 fine copper welding cable in fine condition (30ft looks like it's never been used), 30ft of 8-4 SOOW, and 30ft of 6-4 SOOW and 4 6ft lengths of 2/0 , and a 6ft power cord
17:41 any86362815 for $47
17:41 any86362815 oh, mine is also gas driven, but not running
17:41 rue_school I wonder if thats the cable that was stolen from us over here in canada
17:41 any86362815 be silly to run a pressure washer in theliving room
17:41 rue_school does ithave camlocks on it?
17:41 any86362815 yep
17:41 rue_school blue red and white?
17:41 rue_school er black
17:42 any86362815 has good female camlocks, no good males tho
17:42 rue_school we didn't make a white
17:42 any86362815 black
17:42 rue_school ah, all ours were new
17:42 any86362815 one of the 30ft 2/0 is new , looks never dragged across the gnd
17:42 rue_school ok, I can rotate a line around an arbitrary point, and when I rotate it 0 degrees, it stays in the same place (now)
17:43 rue_school wow
17:43 any86362815 yeas, on a dollar per stuff ratio, i scored good
17:43 any86362815 there is a whole 50 gallon drum almost full of such cable, i cherry picked it for 30 minutes
17:44 any86362815 got the short 2/0 to replace the lil starter cables in the diesel, the SOOW for pieces to jumper tween ups batteries, the new long to extend my arc welder hot cable
17:45 rue_school ok, I now have a function that can get the midpoint of a line,
17:45 rue_school one that will rotate a line around a point
17:45 rue_school now I need one that gets the intersection of two lines
17:45 any86362815 that still leaves me a lot of #6 4-cond and a fair amount of #8 4cond
17:46 any86362815 and have a **spare** 30ft 2/0 welding cable
17:46 any86362815 why are you rotating lines around?
17:46 any86362815 can't you just draw new lines?
17:47 rue_school I need a program to work out
17:47 rue_school THE PRESSUREWASHER STOPPED!
17:47 any86362815 to work out?
17:47 y86362815 hand rue dumbells and jogging sh
17:47 rue_school to work out, given 3 points, what a circle would be that hits them all
17:48 any86362815 i told ya that the otehr nite, and waited 1.5 hrs, you never replied
17:48 rue_school I'm using perpendicular midpoint intersectors
17:48 Tom_itx inscribed circle
17:48 rue_school oh, I was out till 10, had to sneak back into rez and quietly make supper, eat and get to bed
17:49 any86362815 "rez" ?
17:49 rue_school point2d_t * getIntersection(point2d_t is, line_t * this, line_t * that);
17:49 rue_school school residence
17:49 Tom_itx http://2000clicks.com/mathhelp/GeometryConicSectionCircleEquationGivenThreePoints.aspx
17:49 any86362815 oh
17:50 rue_school Tom_itx, there is a math solution but its really ugly and requires a tripple simotanious solution, which I'd have to write a new library for
17:50 Tom_itx my cad will do it too
17:50 rue_school and it goes wrong easy
17:50 any86362815 hey,, i said this :
17:50 rue_school yea, I'm writing a program to make gears
17:50 any86362815 Start with these three equations:
17:50 any86362815 (a-h)� + (b-k)� = r�
17:50 any86362815 (c-h)� + (d-k)� = r�
17:50 any86362815 (e-h)� + (f-k)� = r�
17:50 any86362815 only i used words
17:50 rue_school thanks kat...
17:50 Tom_itx and it's also in the book i got
17:50 any86362815 books of math tricks is good to have
17:50 rue_school and I need to expand my 2d C library to do things to draw the gears
17:51 rue_school I'm using a geometric solution with the library I have, its less overhead
17:51 rue_school 2 rotations and an intersection
17:51 rue_school done
17:53 any86362815-afk food, drying off, too sweaty
17:53 rue_school I'm also interested in a fn that trims a line to a particular length from one end.
17:54 rue_school ok, quick nap, then shopping, then eating, little coding on either side, sleep, repeat.
18:18 rue_school how long was I out?
18:38 Tom_itx quick
20:17 rue_school http://hessmer.org/gears/InvoluteSpurGearBuilder.html
20:17 rue_school ! :0
20:17 rue_school :0
20:17 rue_school :)
21:20 rue_school huh, I just remmebered part of a strange dream
21:20 any86362815-afk how do you know you woke up?
21:22 rue_school I think I'm awake
21:24 any86362815-afk i've thought that before too
21:30 any86362815-afk it's 9pm, do you know which reality you are currently in?
21:30 rue_school no
21:31 any86362815-afk it's 9pm, do you know if you are in a reality?
21:36 y86362815-afk has decided her current most fav bands are: The Liverbirds , Four Jacks And A Jill , and Cryan' Sh
21:37 rue_school I dont knwo any of them
21:38 any86362815-afk i think they all quit making music in the early 1970's, but they have wikipedia pages
21:38 any86362815-afk i keep being surprised about all the bands the usa radio stations didn't play back then
21:55 zhanx ok beaglebone is headless for sure now, the hdmi is disabled and i dont have a dwm anymore
22:08 any86362815-afk how will you see what it's doing, get crash reports?
22:08 zhanx ssh to it
22:08 any86362815-afk stdout goes to ssh?
22:08 Tom_itx hope there's a way to reset defaults if ssh goes wonky
22:09 any86362815-afk if it goes wonky, all you'll know is it isn't reponding
22:10 zhanx i scripted the onboard led's for that
22:10 any86362815-afk script an on-boot to check a jumper for dis/enable the display
22:11 zhanx could do that
22:12 zhanx jujmper to disable of course
22:14 any86362815-afk i once blew the output of a chip on purpose, the reason was so the circuit would not work if the chip was not plugged in, and it wouldn't work if a good non-blown chip was installed
22:16 zhanx cheating
22:17 any86362815-afk i spose
22:17 any86362815-afk nowadaze you can scrape the lettering off an avr and put ttl chip names on it
22:18 zhanx or leave it blank
22:18 any86362815-afk "this 74ls74 isn't acting like a flipflop"
22:19 zhanx saw a video on youtube a while back, a guy was hiding a chip under a chip etc
22:19 zhanx sneaky
22:20 any86362815-afk olde trick, hiding smd parts under dip packages (or in/under their sockets)
22:20 zhanx multi layer boards etc
22:21 any86362815-afk now, you connect to a pin with a buried layer, and put surface traces that don't go to anything
22:26 rue_school if you have to do all that, your not doing enough R&D, cause by the time someone reverse engineers it you should be onto the next better thing anhow
22:28 any86362815-afk umm, peopl are onto newer scopes than the Tek 7603, but i still use the 7603 because i could get it, and it's lugins
22:28 any86362815-afk plugins
22:29 rue_school imagine if tek's technology had increased at a constant rate
22:29 rue_school today that would be amazing
22:30 any86362815-afk mind blowing
22:32 any86362815-afk in the 1970's Tek made optons on the scopes and plugins for fiber optics, but the light-to-electronics were not fast enough then to bother integration of them
22:32 any86362815-afk they did built and sell one fiber-plugin for the TM500 mainframes
22:34 any86362815-afk i would expect to see a whole Tek scope 1/2 the size of one old plugin, with an analog bandwidth of 100Ghz, and terahz adc in it
22:36 any86362815-afk the 7104 can be tweaked to 14Ghz, if it were further tweaked to be an analog-digital converter, it would prolly do 8bits at 14Gsps
22:37 any86362815-afk i dunno what i/o pipe can handle that, or what ram system could store data that fast
22:37 any86362815-afk a GB would store only 70ms of signal at 14gsps
22:50 y86362815-afk hollows out a dip40 package, puts in four 6502 qfp, a couple of tiny13 and 2313, a 128MB ram, a wifi chip, a few srams, and a buss controller to mux all the dip40's
22:58 y86362815-afk ponders putting dip40 pins on top of the package
