[00:15:13] <rue_house> hahahahahaha
[00:15:15] <rue_house> hahahaha
[00:29:03] * katsmeow tries to load it again
[00:30:03] <katsmeow> how does the cat feel about being virtually petted?
[00:31:36] <katsmeow> http://imgur.com/a/JtGVI <<== heck with teh guy in the hoodie, look at the muscles on that girl !
[00:31:53] <katsmeow> oh, nevermind, that'sa guy
[00:32:19] * katsmeow gives up n loading that page
[00:33:56] <katsmeow> 24000 PCS ON SEMI MMBT2907ALT1 TRANSISTORS
[00:34:11] <katsmeow> 2000 PCS SIEMENS V23079-A1001-B201 RELAYS
[00:48:31] <rue_house> 2907....
[00:48:56] <rue_house> akg, smt
[00:49:34] <rue_house> but thanks
[00:49:59] <katsmeow> 288 PCS INTEGRATED DEVICE TECHNOLOGY IDT71V432S7PF INTEGRATED CIRCUITS $4.50 ; 32k x 32 bit synchronous sram
[00:50:45] <rue_house> smt
[00:50:56] <rue_house> I cant even make pcb's for that one
[00:50:56] <katsmeow> tqfp
[00:51:24] <rue_house> +C $47.06 shipping
[00:59:37] <katsmeow> 20 page data sheet, and no spec on how fast thise dac will make outputs
[01:06:05] <rue_house> I'm wondering how I should handle the code for making DACs from the tiny26, it needs to be time-stable because its part of a servo loop
[01:08:17] <katsmeow> RC to convert the pwm to dc ?
[01:08:57] <rue_house> I'm sorry
[01:09:01] <rue_house> ADC
[01:09:23] <rue_house> the tiny26 has 11 adc channels, I want to make them into adcs for the servo loops
[01:09:42] <katsmeow> well, since it's ONE adc in the ship, and a analog mux ahed of it, the code is going tobe busy
[01:10:18] <rue_house> thats all multi channel adcs are anyhow
[01:10:27] <rue_house> but for a 10 bit adc, the tiny26 are MUCH cheaper
[01:10:35] <rue_house> 11 channel 10 bits
[01:11:09] <katsmeow> not arguing the price logic
[01:11:43] <katsmeow> just that yo cannot put one tiny26 on the arm and get a simultaneous sample of the entire arm at the same time
[01:11:54] <rue_house> no
[01:12:03] <rue_house> but it cant calculate all the loops at once anyhow
[01:12:14] <rue_house> you stage the channel calcs
[01:12:48] <rue_house> the samples and calcs need to happen at regular time intervals, aside form that, its open
[01:12:58] <rue_house> I'm thinking between 100-200Hz
[01:13:20] <rue_house> maybe 300hz pwm on the motors, hmm
[01:15:20] <rue_house> I suppose the sample rate could be same as the pwm rate,
[01:15:24] <rue_house> no need to be higher
[01:15:31] <rue_house> from there, its all latency
[01:25:25] * katsmeow is falling asleep
[01:25:27] <katsmeow> gnites
[22:15:07] <katsmeow> what's a good real time clock chip that's not pricey and has an alarm-time setting?
[22:15:54] <katsmeow> DS1337 ?
[22:25:39] <katsmeow> {"data":{"error":"Imgur is temporarily over capacity. Please try again later."},"success":false,"status":500}
[22:35:38] <rue_shop3> there is no such thing as a perfect 90* universaljoijnt
[22:36:29] <rue_shop3> DS1287
[22:36:29] <katsmeow> yo use 90 degree bevel gears, silly
[22:37:05] <rue_shop3> I mean for the robot wrist
[22:37:20] <rue_shop3> without making one of those other things your always on about :)
[22:37:47] <katsmeow> depending on stuff, you can rotate the axiees from 90 thru 0 and to the other 90
[22:38:00] <rue_shop3> but not both 90s at once
[22:38:20] <katsmeow> use a flexidrive cable off a dremel?
[22:38:41] <rue_shop3> its a wrist, the x and y angles need to be controlled
[22:38:46] <katsmeow> no, not both 90's, cause then you'd have 2 output shafts
[22:38:52] <rue_shop3> its not for rotary drive
[22:39:08] <katsmeow> the universal is not for rotary? then what?
[22:39:18] <rue_shop3> x and y tip of the wrist
[22:43:20] <rue_shop3> if I wasn't trying for 90 degrees, I wouldn't have a problem
[22:43:35] <rue_shop3> maybe this is why industrial robots use twist-tip-twist
[22:43:44] <rue_shop3> instead of twist-tip-tip
[22:44:21] * katsmeow looks blank
[23:00:24] <rue_shop3> if you look at the gripper of most industrail robots
[23:00:47] <rue_shop3> they rotate the forearm, then have one tipping axis, then they have another rotation before the gripper
[23:00:51] <rue_shop3> I'm not doing that
[23:01:06] <rue_shop3> I'm doing a roataing forearm, then a 2d tipping
[23:01:19] <rue_shop3> different means to the same thing
[23:01:26] <katsmeow> make an avi/mp3 ?
[23:01:27] <rue_shop3> more or less
[23:02:47] <rue_shop3> the universal is my 2d tipping mechanism
[23:03:15] <rue_shop3> the twist and the universal give me the ability to orient the gripper however I want
[23:08:37] * katsmeow cannot pisture what you are talking about
[23:08:48] <katsmeow> cannot picture it either
[23:11:29] <rue_shop3> your arm is a twist-tip-tip
[23:11:35] <rue_shop3> you can twist your forearm
[23:11:46] <rue_shop3> and your wrist tips in two dimensions
[23:13:38] <katsmeow> so yp are having trouble puttng a twist-bearing into a universal?
[23:18:51] <rue_shop3> soyo can align your gripper to the workpeice you want to pick up
[23:19:11] <rue_shop3> the arms I'v made so far are one axis short
[23:19:30] <rue_shop3> they can not align the gripper sideways to the object they want to grip
[23:19:34] <rue_shop3> just up and down
[23:20:06] <katsmeow> http://DesignerThinking.com/images/catandcat6.jpg <<== yelling online
[23:20:26] <rue_shop3> heh
[23:20:59] <katsmeow> http://imgur.com/gallery/2eCa3lr
[23:21:21] <katsmeow> wow@cpus under the bed
[23:23:29] <rue_shop3> wow i been way too close to that too many times in my life
[23:24:38] <katsmeow> i wouldn't put the puters under the bed, too flammable
[23:28:05] <rue_shop3> making a star from a peice of 1" steel pipe
[23:28:14] <rue_shop3> I wonder if she's coding
[23:28:37] <rue_shop3> the only reason to monitor that many computers at once is hacking
[23:30:17] <rue_shop3> she spends a lot of time there, I suspect she dosn't have much of a social life
[23:30:46] <rue_shop3> tho I suspect she uses the computer to pay her way
[23:30:47] <rue_shop3> s
[23:32:40] <katsmeow> you know it's a fantasy painting, right?
[23:32:58] <katsmeow> no one has a ceiling that tall, cept me, upstairs
[23:33:42] <katsmeow> at the skylights, which all leak now in the rain, i can stand up a 16ft 2x4 and not hit the unfinished ceiling
[23:34:01] <katsmeow> the underside of ther oof in the center is 12ft off the floor
[23:34:59] <rue_shop3> thebear had a high cieling like that
[23:35:49] <rue_shop3> she dosn't do art, or there would be some on the walls
[23:36:03] <katsmeow> you did a bit of traveling in Oz when visiting ..... <nick>, eh?
[23:36:11] <rue_shop3> the selection of clothes points out the lack of outside social life
[23:36:23] <rue_shop3> rifraf
[23:37:07] <rue_shop3> I'd say she's between 16 and 21
[23:37:36] <rue_shop3> dosn't use the freezer
[23:38:01] <rue_shop3> interesting, no microwave or pizza boxes
[23:38:27] <katsmeow> you know it's a fantasy painting, right? not a design plan to live by?
[23:38:51] <rue_shop3> but she does eat in her rom
[23:38:53] <rue_shop3> room
[23:39:00] <rue_shop3> maybe they cleaned it up a bit
[23:40:17] <katsmeow> to be realistic, she'd be wearing baggy shorts (with pockets) and no undies
[23:41:07] <rue_shop3> mmm
[23:41:12] <rue_shop3> not sure on that one
[23:43:09] * katsmeow points out that she may know what wimin do
[23:43:58] <rue_shop3> k, well, deep at night, on summer days, when coding for 48 hours straight, I wasn't wearing anything. :P
[23:44:57] <katsmeow> it's just that the bikini undies in that pic are a male's dream, not comfortable wear for coding alone
[23:45:56] <rue_shop3> I think there to avoid the extra erotic that it would have if she weren't wearing anything cause thats not what the pic is about
[23:46:30] <katsmeow> do i NEED to take a pic of baggy shorts?
[23:48:34] <rue_shop3> no
[23:49:04] <katsmeow> they are a nice shade of blue
[23:49:17] <katsmeow> with pockets
[23:49:27] <katsmeow> because of the storm, i have a flashlite in one pocket
[23:53:06] <rue_shop3> so, if it weren't for the storm, you would have a flashlight in both?
[23:54:28] <rue_shop3> oops, I think I need a 4th dimension to make this joint work
[23:55:17] <katsmeow> time
[23:57:05] <rue_shop3> well, if I can simotaniously have one of these peices here and not here then it'll work
