00:00 Tom_itx mostly for rue
00:00 katsmeow-afk i don't do nix
00:00 Tom_itx thus
00:00 Tom_itx mostly for rue
00:00 Tom_itx you could ya know
00:01 katsmeow-afk or, i could do othe things
00:01 Tom_itx or that
00:02 katsmeow-afk i forgot i left some plexi and calipers up at the bandsaw to do something about that plexi being in one piece
00:02 Tom_itx i can't remember what i forgot
00:16 katsmeow-afk well, the too-thin plexi is too thin
11:05 Tom_itx rue_shop3, is 'interfaces' the only file i need to edit for a static ip?
11:54 katsmeow-afk listing for 50 GB of mobo ram is up to $15 now
11:55 tsmeow-afk feels like going to the hallway and looking at the olde calculator, it was $100 *per byte* of
11:58 katsmeow-afk new "improvement" to ebay: not showing s&h in watch list
12:02 katsmeow-afk anotehr thing someone said in the store yesterday: i must not be from round here because i have no accent
12:03 katsmeow-afk but i have no accent, i choose to pronounce the words in english correctly
12:03 katsmeow-afk pronouncing them incorrectly isn't really an "accent"
12:07 katsmeow-afk if i i said "enVLOPee" for "ENvelope" might be bad accenting, it's certainly bad pronunciation
12:09 katsmeow-afk so your justification for saying the word wrong is that you don't live in the north? The people living in South Africa (the nation) don't live in the northern usa either, but they say the word correctly.......
12:33 tsmeow-afk rolls morsels of cat food around the shop for rue's cats to c
12:34 katsmeow-afk did you know there is a speed limit to what they will or will not chase? for instance, using a rubber band to launch the morsels will make them exceed the cat's speed limit
12:36 katsmeow-afk if you form the morsel onto the last 1/2 inch of a thread, and tie the other end to a ceiling fan, only the slowest fan speed will cause the cat to go for the morsel
12:41 katsmeow-afk imagine, the cat is accustomed to the fan coming on when they enter a room, then they hop onto a chair, and they see morsels of food slide off the armrests (and table tops) and fly around the room
12:50 rue_another do you think that vocal chords produce more of a square or sine wave (raw)
12:50 Tom_itx sine
12:51 Tom_itx they are vibrating and must accelerate and decelerate
12:51 rue_another kat yes, if I flick nibbles too fast down the hall they just watch it go by
12:51 Tom_itx do the mice get them instead?
12:52 rue_another the cats walk around and clean them up later
12:52 Tom_itx the mice or the food? :)
12:52 rue_another but its true, there interest has a maximun velocity
12:52 rue_another :)
12:53 rue_another I'm having a hard time working out how to live with my duality
12:53 tsmeow-afk
12:53 katsmeow-afk a "burce jenner" duality ?
12:54 rue_another this whole "I need space to store the printers I drag home to be stripped apart" vs "I need space for a potato patch"
12:54 katsmeow-afk your harmonics, all combined, can produce waveforms other than sine, but the vocal chords must produce only sine
12:54 rue_another I need space for welding, but where should the fucia be planted?
12:55 Tom_itx rue_another, is interfaces the only file i need to edit for static ip?
12:55 katsmeow-afk you don't plant the fucia inside anyhow
12:55 katsmeow-afk and you have the livingroom with 3 side of huge glass for that
12:55 rue_another your sure? I think its the other way around, the vacal chords are producing something 'more' square, and the nasal cavity can filter it off
12:55 rue_another Tom_itx, yes
12:55 Tom_itx rue_another, nope it's sine
12:55 katsmeow-afk nasal cavitys peak stuff because they are tuned resonators
12:56 Tom_itx due to the acceleration deceleration of the tissue
12:56 rue_another I cant weld in the living room, the carpet would be ruined
12:56 katsmeow-afk weld in the workshop, or outside
12:56 rue_another ah, so, your saying nasal cavity is a fourier resonance cavity that can take a fundamental freq and square it up
12:57 katsmeow-afk no, it will peak the higher harmonics, which might square the fundamental
12:57 rue_another this is cool, I have to ponder this
12:58 Tom_itx it's a flapper valve
12:58 katsmeow-afk nasal cavities are small, in women, even smaller, they won't affect the fndamental of either at that low freq (under 1khz)
12:58 rue_another the tone from a non-nasal passthru still sounds more square to me
12:58 Tom_itx scope it
12:58 katsmeow-afk you heard someone with no nasals?
12:58 rue_another I will
12:59 rue_another but its a complex wave
12:59 rue_another katsmeow-afk, no
12:59 katsmeow-afk ok, spectrum analyse it
13:00 rue_another I'v spectrumed it beofre but because its all got lots of harmonic distortion, all you can see are aliases
13:01 rue_another but clearly on the scope a single tone is some mix of two waves
13:01 katsmeow-afk 3D print the nasal cavities, build a flexable windpipe and rubber flapper valve, add LPLV air source, make it speak
13:01 katsmeow-afk if you print the cavities in a way you can adjust them too, experiment
13:02 rue_another :) I call it trombonehead
13:03 katsmeow-afk goop them up, so dey thounb fpunny lite dey hab a code
13:04 rue_another point taken
13:04 rue_another I'm trying to think of how to code a set of resonators
13:05 rue_another I suppose like an LC filter
13:05 katsmeow-afk "cycle thru all settings till you produce this sound, now i am going to bed, see you in the morning"
13:06 katsmeow-afk <later that nite neighbors call the police because of all the wierd screaming coming from rue's shop>
13:06 rue_another this would suggest that changing your vocal chord pitch and activate and deactivate different resonance chambers
13:06 katsmeow-afk it does
13:06 rue_another :/ the model I was gonna use was simple
13:06 rue_another that said
13:07 rue_another ok, wait
13:07 katsmeow-afk it can be, tweak some filters to the point of almost sustained oscillation when they see their bandpass freqs
13:07 katsmeow-afk a lil feedback shold do it
13:07 katsmeow-afk controllable
13:08 rue_another is the dual wave nature of the vocal chord origionate at the chords or is it a reflection from the nasals
13:08 katsmeow-afk the cords
13:09 rue_another k, closing off nasals should prove that
13:09 katsmeow-afk the nasals cannot make enough energy to reflect back down the throat and modulate the cords
13:09 rue_another how many nasal cavities are in a standard human?
13:09 rue_another 4? 6?...
13:10 katsmeow-afk the *cavities* are resonant, the *nasal channels* are inline filters
13:10 katsmeow-afk 4, iirc, not counting the throat itself (above and below the cords), the mouth, and the external nose itself
13:12 katsmeow-afk also, keep in mind, none of it is hard-surfaced except the teeth, the rest of it is a bio-layer that can also vibrate
13:13 tsmeow-afk is such a
13:14 rue_another er, I see 4 per side, = 8... I dont know if they are all part of the air path becuase of ISOMETRIC VIEWS
13:14 katsmeow-afk 8??
13:17 rue_another well, I can see now that some of the areas are not clearly defined
13:17 rue_another gonna see if I can just find an acoustic model
13:18 rue_another I'm an idiot!
13:18 rue_another I can just freq sweep a human!
13:18 katsmeow-afk yeas, to some extent, you can
13:18 rue_another no, I mean inject sound
13:18 katsmeow-afk that's what i said
13:18 rue_another pass it thru the nasal cavities
13:19 rue_another then I can profile it
13:19 katsmeow-afk people minus vocal cords use a vibrator to inject sounds
13:27 Tom_itx rue_another, where do i find the 'broadcast' address for the lan?
13:28 katsmeow-afk network setup
13:29 Tom_itx this is linux
13:29 katsmeow-afk i set my puters for 10.0.0.x
13:29 katsmeow-afk i set internal localhost to 127.0.0.1
13:30 katsmeow-afk that way incoming for localhost cannot find it on the 10.0.0.x cards
13:30 katsmeow-afk and localhost on 127.0.0.x cannot get out
13:34 katsmeow-afk i need to goto outside and do(stuff)
13:34 katsmeow-afk hopefully, i will remember to don welding jacket
13:39 rue_another eth1 Link encap:Ethernet HWaddr 00eth1 Link encap:Ethernet HWaddr 00:a0:24:aa:1e:10
13:39 rue_another inet addr:192.168.8.247 Bcast:192.168.8.255 Mask:255.255.255.0

13:39 rue_another inet addr:192.168.8.247 Bcast:192.168.8.255 Mask:255.255.255.0
13:39 rue_another the broadcast address is the network address with all the bits of the mask that are zero set to 1
13:40 rue_another if your using 192.168.1.x on your network, your broadcast is 192.168.1.255
13:41 rue_another inet addr:192.168.8.247 Bcast:192.168.8.255 Mask:255.255.255.0
13:41 rue_another paste got stuff in it
13:42 rue_another broadcast is (mask & IP) | (~mask)
13:44 Tom_itx 192.168.0.1
13:45 rue_another prolly 192.168.0.255 then
13:45 rue_another with a rare chance of 192.168.255.255
13:46 Tom_itx just the last digits of the address?
13:46 Tom_itx the .1
14:12 rue_house are all your addresses 192.168.1.*
14:12 rue_house if so, use 192.168.1.255
14:12 rue_house it says that anything outside of 192.168.1.* isn't accessable unless you go thru the router
14:13 rue_house hmmovercast day
16:53 tsmeow-afk wants ahealthy dinner early t
17:04 tsmeow-afk has the axle-spring mounts all done for one side, ready to weld to the frame, and a few cuts for the other side and it wil be ready
17:05 katsmeow-afk it's sooooo tempting to make it a sliding axle, but i would rather not spend more time doing that
17:05 katsmeow-afk a steerable axle would be a luxury hoot too
17:08 katsmeow-afk erg,, i accidently won 3 flycutters, i bid min bid on them last week, didn't check them, no one bid against me, $15 including s&h, straight 1/2 shank
17:09 katsmeow-afk AAARRGGG i didn't check that 60 GIGABYTES of ram either, it went for $17
17:10 katsmeow-afk 3000 PCS FAIRCHILD BCX71H/NL
17:10 katsmeow-afk $2.99
17:11 katsmeow-afk 180 pcs of gold plated serial ports $4
17:12 katsmeow-afk 1000 pcs of various capacitors, under $5
17:13 Tom_itx i bet your electric bill goes up alot when you weld
17:14 katsmeow-afk i have not been able to verify how much tho
17:15 Tom_itx been doing the initial 'windows updates'
17:15 katsmeow-afk figure 8kw, 13 cents each kw, ~$1 for an hr of continuous welding
17:15 katsmeow-afk a solid state welder would prolly use 1/2 the power
17:15 katsmeow-afk saving 50 cents to pay for a $1000 welder doesn't make sense atm tho
17:16 Tom_itx likely last half as long too
17:16 katsmeow-afk true, a growel box can talke a lot of abuse, and is more hackable, and will keep runing unless it's melted down
17:23 katsmeow-afk why would someone sell 100 pcs of puter fan in one lot?

21:00 katsmeow-afk hey, i think my car is legally an antique this yr, it turns 25, i think the license plate may be free
21:00 katsmeow-afk or turned last yr
21:02 katsmeow-afk nope, rule is now 30 yrs old
21:02 katsmeow-afk and cannot be used to transport passengers or property or driving to work, school or shopping
21:05 Tom_itx guess you'll be doing alot of joy riding
21:06 katsmeow-afk or i'll be living primarily on a boat, making it too difficult to use the car
21:07 katsmeow-afk the trailer i are building is to transport steel plate for the boat sitting under the trailer i am building
21:08 katsmeow-afk i have 1 plate 3x8 , need 3 more to finish the deck on this boat, and then will need 2 (?) more 5x10 18awg plates for the other float
21:08 katsmeow-afk cannot move those on the baby 6ft long trailer
21:09 katsmeow-afk and cannot drag the 16ft bed trailer behind the car
21:57 katsmeow-afk http://www.walmart.com/ip/EverStart-24MS-6-Marine-Battery/16782694 <<== Battery Type: Does Not Contain a Battery
22:49 rue_house I think they mean that litteraly
22:49 rue_house it IS a battery, does not contain a battery
22:49 rue_house whats a 6244?
22:49 rue_house 6
22:50 rue_house oh 162445
22:50 rue_house so its 16 bits
22:50 katsmeow-afk 16 bit 74245
22:50 rue_house 244, whats the 5 for?
22:50 rue_house oh, then whats the 2 for?
22:50 katsmeow-afk 5?
22:50 rue_house 2?
22:50 katsmeow-afk 24
22:50 rue_house 162 245
22:50 rue_house 16 bit, 2? 245
22:50 katsmeow-afk has a thing in it
22:51 rue_house I'd ask if its binary, but its a 245, its trinary
22:51 rue_house ATMEL10425128W <ii I cant work out if its 1k or 512k
22:51 tsmeow-afk doesn't
22:51 rue_house or 128k
22:52 e_house squ
22:52 rue_house I want to write a throat, as an android, I'll need one
22:53 katsmeow-afk to speak? why not use a speaker?
22:56 katsmeow-afk the extra 2 = 22 ohm series resistors on A port
22:57 katsmeow-afk TI is saying the LVTH is a ABT in disguise, the H = buss hold (so no wandering tristate voltages, even when tristated)
22:58 katsmeow-afk 3.3v but 5v interfacing
22:58 katsmeow-afk since 5v vcc = 2.4v logic 1 , and a good 3.3v also = 2.4v logic 1 .... <shrug>
22:59 katsmeow-afk it's a biiiiggg chip: 48 pins
22:59 katsmeow-afk gnd and vcc pins all over it
23:00 katsmeow-afk DGGR = tsop
23:20 rue_house To Small, Outof Patience.
23:20 rue_house I'm gonna live for 45 more minutes
23:20 rue_house I hope they are goood minutes
23:28 tsmeow-afk doesn't remember that
23:29 katsmeow-afk finally, new ups battery is connected to the ups, altho it's the lil 300w auto-ups, not a real invertor
23:35 katsmeow-afk how does one use a MSM7533V analog 2-channel codec ?
23:36 katsmeow-afk 700 PCS OKI MSM7533V
23:36 katsmeow-afk $3.99
23:36 katsmeow-afk 1 bid
23:36 katsmeow-afk +$19.48 shipping
23:43 katsmeow-afk 1MB x 16 srams, but they are the tineyest of BGA packages
23:45 rue_shop3 2 channel codec, I susect one rx and one tx, prolly for 8khz ulaw audio
23:46 katsmeow-afk i have the data sheet, but i don't have the telco that it wants to sync to
23:46 rue_shop3 transformers should not be front and cetre in the electronics workbench
23:46 rue_shop3 and welding gear should be in mechanical
23:47 rue_shop3 or by the welding stuff by the door
23:47 katsmeow-afk what about a variac?
23:47 rue_shop3 what do I do with the corner square under where two benches meet at 90 degrees, kinda useless space
23:47 rue_shop3 electronics workbench has a whole lot of space taken up by boxes of transformers
23:47 katsmeow-afk take out the leg there, and insert a "lazy susan"
23:47 rue_shop3 technically, the box of AC adapters would be better suited
23:48 rue_shop3 hmm
23:48 rue_shop3 thats an idea I forgot about
23:48 katsmeow-afk or, a robot arm, you ask for something, it looks for it back in that space, and hands it to you
23:48 katsmeow-afk "diet coke, please"
23:49 rue_shop3 "it just tried to hand me its microcontroller again"
23:49 rue_shop3 hmm
23:49 katsmeow-afk how did it complete the action!?
23:49 rue_shop3 right above one of them I have a speaker taking up usefull space
23:50 katsmeow-afk some of that stuff can go avove the water heater, if you insulate that thing better
23:50 katsmeow-afk put it in a box
23:50 rue_shop3 ok I will remove the transforers and repalce them with something
23:50 katsmeow-afk paint it like a microTardis
23:50 rue_shop3 ah, tardis, I should use some timelord tech in the shop
23:50 tsmeow-afk
23:51 katsmeow-afk it's how i got a 24 x 48 ft living room into my house
23:51 rue_shop3 I could swap heatsinks with a box of baords ont eh back shelf
23:52 katsmeow-afk no, boards make poor heatsinks
23:52 rue_shop3 it might bump the power bill, a tardis has a big power source to do that stuff
23:52 rue_shop3 I'm trying to fix oranization problems
23:52 rue_shop3 g
23:52 rue_shop3 -----------------------------^
23:53 rue_shop3 ugh, insert it where yo like then
23:53 rue_shop3 u
23:53 katsmeow-afk wow, don't see much 4052 anymore, specially in a lot of 2400
23:55 katsmeow-afk someone wants those TL082 , bidding is $30 already, 18 hrs before end of auction, for 1645 of them
23:55 rue_shop3 yup, almost the whole front bench needs to be pulled apart and redone
23:55 katsmeow-afk but you just built it last yr?
23:56 rue_shop3 no that was a back shelf,
23:56 katsmeow-afk oh
23:56 rue_shop3 I have to pull out all the stuff and reorganize
23:56 rue_shop3 its full of things in wrong places and stuff that is never used in the spaces you need things
23:56 katsmeow-afk 3000 3906's $8.50 so far
23:57 rue_shop3 LM3914 scope?
23:57 rue_shop3 100 leds, ...
23:57 rue_shop3 hmm, that would cost much these days
23:57 rue_shop3 wouldn't
23:58 katsmeow-afk wall size tho?
23:58 rue_shop3 4017 and a lm3914
23:58 rue_shop3 and a 555
23:58 rue_shop3 hmm
23:58 rue_shop3 tl071 for a trigger?
23:59 rue_shop3 see any 3mmish square leds?
23:59 katsmeow-afk there was a reel of them went earlier for a few bucks
23:59 rue_shop3 not smt
23:59 rue_shop3 soemthign you can pack up against each other
23:59 rue_shop3 pixels ya know
