[00:01:55] <katsmeow> two pics of the nite's activities : http://DesignerThinking.com/images/DSCF6757m.jpg http://DesignerThinking.com/images/DSCF6758m.jpg
[00:43:16] <rue_shop3> exhausted
[00:43:29] <rue_shop3> starting to get the shop re-assembled
[00:43:50] <rue_shop3> I need somwehere to put this rather large robotic arm
[00:44:43] <katsmeow> backpack i think it appropriate
[00:51:45] <katsmeow> attach it to the center of the ceiling so it can reach most of the room
[00:52:06] <katsmeow> it can manage the center table, and fetch parts from shelves on the wall
[01:00:58] <katsmeow> rue ?
[01:01:05] <rue_house> hi
[01:01:13] <katsmeow> [23:36] <katsmeow> two pics of the nite's activities : http://DesignerThinking.com/images/DSCF6757m.jpg http://DesignerThinking.com/images/DSCF6758m.jpg
[01:01:32] <rue_house> power supply?
[01:01:53] <rue_house> you have one of the good old solder suckers like me
[01:02:04] <katsmeow> dual h-bridge audio amp, if it works, never seen a schematic like i am building
[01:02:13] <rue_house> part of mine snapped off tho
[01:02:26] <rue_house> ah, nice
[01:02:32] <katsmeow> and no adjustments, and should be very stable
[01:02:45] <katsmeow> no global feedback either
[01:03:14] <rue_house> I hope you keep me updates
[01:03:16] <rue_house> d
[01:03:21] <rue_house> ugh, I'm exhausted
[01:04:01] <katsmeow> i'm building in the smallest steps possible, to test various ideas
[01:04:14] <rue_house> l
[01:04:16] <rue_house> k
[01:05:58] <katsmeow> cannot find my tl082 , so using lm324 , leaving tons of opamps unused
[01:06:22] <katsmeow> and the 324 isn't even a great opamp, but it works
[01:06:50] <rue_house> I can send you some 082 if you dont mind waiting 2 months for them to get there
[01:08:03] <katsmeow> can you spare 5?
[01:08:10] <katsmeow> are they dips?
[01:08:22] <rue_house> they are dip, I dont know how many I hve
[01:08:30] <rue_house> I have a bunch of 072 or 082
[01:08:42] <katsmeow> either one, or i can get them on ebay
[01:08:58] <rue_house> canada post is REALLY slow
[01:08:59] <katsmeow> i am calling the LM324 the worst case situation
[01:09:19] <rue_house> I have to go shut down the shop I'll see what i have
[01:09:44] <rue_house> what are the mechanics of a brain being tired kat, so far it looks like dehydration and lack of oxygen
[01:10:26] <katsmeow> the neurotransmitters and their mediators cannot be cleared and recyled fast enough
[01:11:21] <katsmeow> they keep building up, evelutionarily, the brain onely neded to work sunup till sundown
[01:11:46] <katsmeow> so after sundown, the human went to sleep, the brain cautght up by morning
[01:15:10] <rue_shop3> 072, are you shure you would not like 074 instead?
[01:15:51] <katsmeow> it's the quad packs that are wasting me opamps and board space
[01:16:07] <rue_shop3> ok
[01:16:16] <rue_shop3> 5x072
[01:16:47] <rue_shop3> I wonder, would you like to have me anc china race?

[01:20:02] <rue_shop3> Tom_itx, do you remember how long that stuff I sent you took?
[01:20:34] <rue_shop3> things from china take 22 days, but I'v leaned they only take 5 days to get to canada
[01:21:02] <rue_shop3> last week I got a package that arrived i canada _2_ months ago
[01:22:04] <katsmeow> did it sit in customs, because that's the custom?
[01:22:16] <rue_shop3> I think so
[01:26:35] <katsmeow> remember when those were a couple bucks each when we had to buy from ratshack or mouser or newark or hamilton-avnet or etc?
[01:26:44] <rue_shop3> yup
[01:28:19] <katsmeow> so this experiment will start with 5 of them for the 2 channel ( 2 h-bridges)
[01:29:41] <katsmeow> oops, 9 of them
[01:29:52] <katsmeow> 5 of them
[01:30:06] <katsmeow> we'll see what works :-)
[01:46:34] <rue_house> I have a bunch of tl071 too
[02:09:57] <katsmeow> gnites

[22:48:12] <rue_shop3> oh I have to paint your digits
[22:50:25] <katsmeow> not really
[22:51:12] <katsmeow> have you considered laying a layer of toilet paper on the first wet paint?
[22:51:32] <katsmeow> thent he 2nd coat wouldn't take any paint at all to cover

[22:53:40] * katsmeow nods
[22:54:33] <rue_shop3> I have a large robot arm I ahve to get out of the way
[22:54:50] <rue_shop3> i'm not bolting it to the cieling
[22:55:17] <katsmeow> then it's gonna fall
[22:55:17] <rue_shop3> not sure what to do with it
[22:55:41] <katsmeow> attach it to the door, so instead of opening the door, it opens the shop
[22:55:43] <rue_shop3> I cant think of a long term plan
[22:57:24] <rue_shop3> maybe if I put it in the living room and have it water the plants more reliably than I do
[22:57:47] * rue_shop3 tries to remember the last time he watered the plants in the livingroom
[22:58:01] * rue_shop3 tries to remember the last time he turned on the tv in the livingroom
[22:58:13] * rue_shop3 tries to remember the last time he was EVER in the livingroom...
[22:58:27] <rue_shop3> I .... DO HAVE a livingroom, right?
[22:59:21] <katsmeow> the plants took it over
[23:00:38] <rue_shop3> damn, I think I have to put the arm back were it was
[23:00:41] <rue_shop3> I watnedt hat space
[23:38:35] <Tom_itx> conversion coming along nicely with a slight learning curve attached
