[00:03:17] <rue_shop3> no, it might have happened a long time ago
[00:03:29] <rue_shop3> I dont usually stare at the door
[00:03:30] <^kat^> did a robot break out?
[00:04:08] <rue_shop3> I have to work out what to do with kids tomoor
[00:04:14] <rue_shop3> I have to focus on that
[00:38:52] <^kat^> http://www.nndb.com/
[00:55:35] <rue_shop3> dosn't come up
[00:59:03] <rue_shop3> kat, did you know that a 78L05 will pull like .5mA with no output load?
[00:59:49] <^kat^> yeas
[01:02:41] <^kat^> This yawning chasm of understanding leads to the second big problem: there is no accepted theory of mind that describes what “thought” actually is.
[01:08:41] <^kat^> 4 webpages long : http://arstechnica.co.uk/information-technology/2015/12/demystifying-artificial-intelligence-no-the-singularity-is-not-just-around-the-corner/
[01:20:32] <^kat^> If you have so far resisted the allure of Windows 10, deciding instead to stick with Windows 7 or Windows 8.1, you may want to keep a closer eye on your PC. This is because several people have had their PCs upgraded to Windows 10 against their wishes. Almost as if Windows 10 has become sentient and started installing itself.
[01:20:41] <^kat^> News of this latest wave of unwanted updates comes courtesy of a Reddit thread comprising almost 3,000 comments. Many are from people who have found their computers upgraded to Windows 10 despite them not actively initiating the upgrade.
[01:20:47] <^kat^> Many also made sure Windows Update wasn’t set to automatically download and install updates, killing that excuse dead.
[01:25:56] <^kat^> Bastille found that anyone using a USB radio dongle, a laptop, and a few lines of code could hack into a wireless mouse from as far away as 200 meters. The hacker essentially masks their device as a wireless mouse,
[01:25:58] <^kat^> latching onto an unencrypted dongle attached to someone’s PC. They can then use their laptop as a wireless keyboard, and control the victim’s computer from afar.

[01:45:05] <^kat^> what the world needs now is a site that's hardened against exploits, you can customise it like you do your browser now, and it sends you enough webpage info in plain jpg/avi/mp4/html to view it
[02:07:38] <rue_shop3> sorry i I'm quiet, I'm trying to work out something for kids robotics tommorow
[08:37:26] <Tom_itx> and i thought you were hunting wabbit
[12:10:24] <rue_shop3> hmmm the illusive rabbit
[21:36:55] <katsmeow> mou mowe
[22:48:25] <katsmeow> http://designerthinking.com/images/rollerframes.html
[23:24:14] <rue_shop3> hey
[23:24:24] <katsmeow> hoo
[23:24:28] <rue_shop3> sorry about yesterday, I was quite busy designing the kids kits
[23:24:41] <rue_shop3> and after all that, and a 2am night, nobody came
[23:24:47] <rue_shop3> tra-la-la
[23:24:49] <katsmeow> :-(
[23:24:59] <rue_shop3> it means I'm preped for next time
[23:25:10] <katsmeow> they prolly didn't wanna take apart more printers
[23:25:29] <rue_shop3> I made a kit for making tractor remotes
[23:26:08] <rue_shop3> http://www.weldingandwelder.com/images/TRI-STAND%201.PNG
[23:26:15] <rue_shop3> I'm making one of those things!
[23:26:27] <rue_shop3> I saw a really simple design last week
[23:26:47] <rue_shop3> I just need rebar for the legs, but it got dark and I cant find any
[23:26:56] <rue_shop3> legs aren't like that tho
[23:27:15] <katsmeow> those have no rebar n them
[23:27:31] <katsmeow> rebar will be wobbley, you need channel and angle, of decent size
[23:27:31] <rue_shop3> one of those things, but not made like that
[23:27:54] <katsmeow> you see the roboboat ?
[23:28:05] <rue_shop3> no
[23:28:24] <rue_shop3> crossfire...
[23:29:02] <rue_shop3> ooo nice work on the bender
[23:29:38] <rue_shop3> :) vise grips
[23:30:02] <katsmeow> it's coming along like i worked out n my head a yr ago, some stuff is beng difficult on purpose, but i ave vise grips, torch, arc welder, etc, it will be beaten into submission
[23:30:06] <rue_shop3> those are the neato ones, with the deep jaw
[23:30:24] <katsmeow> the longer the jaw, the less force it can apply tho
[23:31:15] <katsmeow> which is why i had to builf the new allthread clamp,, which i can also put a hydraulic ram into, but not while arc welding, with my luck i'd weld the ram stationary
[23:31:28] <rue_shop3> for the short little welds, on the L holding the bearing bars, you use about 50/60A?
[23:31:42] <katsmeow> 110 the whole way
[23:31:47] <rue_shop3> woof
[23:32:01] <rue_shop3> that must be a 2-3 second spot weld
[23:32:38] <katsmeow> 2 sec max, and i make sure i cram the hot rod into the joint between the steels first
[23:32:56] <katsmeow> get a deep bead, 3 passes as fast as i can
[23:33:27] <rue_shop3> I"m gradually getting the hang of controlling duty cycle to not melt down the project
[23:33:55] <katsmeow> gotta watch the overall heat too, so it doesn't warp badly
[23:34:37] <katsmeow> i ran those *fast* so the bearings beside the weld don't get hot enough to melt the rubebr seals
[23:35:28] <rue_shop3> I fixed up the dolly from the scrap metal pile
[23:35:46] <rue_shop3> the wheels I had were a bit more of a challange than I thought, one had a bad tube
[23:35:48] <katsmeow> why was your dolly scrapped?
[23:36:02] <rue_shop3> I dragged one out of the scrap pile I was talking about
[23:36:15] <katsmeow> o
[23:36:23] <rue_shop3> its bearings were shot, its wheels disintegrated, and rusty
[23:36:34] <rue_shop3> I got it cause I had a spare set of wheels
[23:36:37] <katsmeow> you see what i said yesterday about the compressors at recycler?
[23:36:47] <rue_shop3> there was a second one there I didn't get cause I'm not out of wheels
[23:36:51] <rue_shop3> yea
[23:36:57] <rue_shop3> do tell if you win them
[23:37:28] <katsmeow> one, the $150 one, i cannot spare $300 for the one that will need 30hp to spin it
[23:38:57] <rue_shop3> I need more paint...
[23:42:22] <rue_shop3> http://stackoverflow.com/jobs/111771/motion-control-software-developer-engineer-zaber-technologies-inc?med=clc&ref=large-sidebar-blue-nearyou
[23:42:25] <rue_shop3> huh
[23:42:41] <katsmeow> ?
[23:52:17] <rue_shop3> ok I need a circuit that runs a tl494 full out
[23:52:28] <rue_shop3> or, I work on a different project
[23:52:36] * rue_shop3 looks around
[23:52:45] <katsmeow> or, deign without the TL494
[23:52:51] <rue_shop3> I had 4 tatter paddies, can I call that supper?
[23:52:53] <katsmeow> destruyu,kuil;ign
[23:53:00] <katsmeow> yeas
[23:53:03] <rue_shop3> kat, I need the limited duty
[23:53:15] <rue_shop3> its the smallest way of doing it
[23:53:35] <katsmeow> psu chip?
[23:53:36] <rue_shop3> its for a push pull votlage doubler
[23:53:39] <rue_shop3> yea
[23:53:52] <rue_shop3> the lawn mowing robots cutter motor needs 24V
[23:53:57] <rue_shop3> the robot runs on 12
[23:54:00] <katsmeow> how much power?
[23:54:10] <katsmeow> oh. motor
[23:54:15] <katsmeow> yipes
[23:54:16] <rue_shop3> cant be that much, I have a 150W ferrite core set up
[23:54:36] <rue_shop3> 6A should be lots
[23:54:45] * katsmeow nods
[23:54:58] <rue_shop3> its a weed eater motor, I dont think it'll pull more than 6A stall at 24V anyhow
[23:55:16] <rue_shop3> not that I can test that, CAUSE I HAVN'T FINISHED MY POWER SUPPLY YET
[23:55:22] * rue_shop3 clears throat
[23:55:33] <katsmeow> 2 batteries, ammeter
[23:55:44] <rue_shop3> oh yea
[23:56:00] <katsmeow> you got your sawed pcb shunt
[23:56:10] <rue_shop3> 20A meter too
[23:56:17] <rue_shop3> er 10, .. whatever
[23:56:42] <rue_shop3> technically
[23:56:57] <rue_shop3> it should be able to take more than 150w
[23:57:13] <katsmeow> i wouldn't lock-rotor it, but a lumber and spring pulling it into the shaft can make a lot of smoke
[23:57:23] <rue_shop3> I'm using a single winding centertapped
[23:57:39] <rue_shop3> the tap goes to +12, the two sides to fets to -
[23:57:50] <katsmeow> 150psi into the output of a car power steering pump can make a lot of noise too
[23:57:52] <rue_shop3> each end also has a diode to the 24V output
[23:58:11] <rue_shop3> so its kinda an autotransformer
[23:58:18] * katsmeow nods
[23:58:18] <rue_shop3> hmmm
[23:58:45] <rue_shop3> its 150W, but at 12V, so thats about 12A
[23:59:04] <rue_shop3> so, about 300W out.... hmm
[23:59:14] <rue_shop3> well, anyhow
[23:59:29] <katsmeow> yanno, i'd recommend 2x 12v , because 12@24 is going to pull 24@12 from the one battery
[23:59:52] <rue_shop3> I'd use a transsistor osc to do the free wheel pushpull, but they dont run nice for me
