12:00 AM rue_: no, thats sin output
12:03 AM katsmeow: ouch
12:03 AM rue_: so, if I have 4 of them I can play music?
12:03 AM rue_: :)
12:03 AM katsmeow: you got 10 fingers, need at least 10 music maker things
12:03 AM katsmeow: plus whatever is i sustain while you hit anotehr 10
12:03 AM rue_: ? they say up to 12.5Mhz
12:03 AM rue_: A+B=!??! WTf?
12:03 AM rue_: hey with 6 I could simulate a guitar!
12:03 AM rue_: .. what did this cost?
12:03 AM katsmeow: powr up the osc, and feed a freq counter, and see what it does
12:04 AM rue_: reading for a while
12:04 AM rue_: I have to talk to it to make it do anything anyhow
12:06 AM fckng_stupid is now known as ^kat^
12:06 AM ^kat^: [12:05:am] <katsmeow> maybe 2 '269's, and a 10Mhz osc
12:06 AM ^kat^: [12:05:am] <katsmeow> 100 Mhz
12:06 AM ^kat^: [12:05:am] * Disconnected
12:06 AM ^kat^: dunno why disconnected
12:09 AM rue_: server bump prolly
12:09 AM katsmeow: dunno why disconnected again, but not connecting from Tx now
12:10 AM katsmeow: well..............
12:11 AM rue_: sorry, I'm not doin much exciting
12:11 AM rue_: I'm having problem with sleep
12:12 AM rue_: its been attacking me at awkward times
12:14 AM rue_: I need to time 8 minutes for the spagetti
12:14 AM katsmeow: and failing to execute when needed?
12:16 AM katsmeow: robot cop "drunk" : http://www.questionablecontent.net/view.php?comic=3697
12:16 AM rue_: you got it
12:18 AM rue_: wow, this is a convoluded datasheet
12:18 AM rue_: they dont just summarize the register addresses, they split it into a bunch of tables
12:19 AM rue_: 13+8 == 1 11
12:19 AM rue_: 21
12:22 AM katsmeow: must be chinese
12:24 AM rue_: (spagetti)
12:26 AM katsmeow: https://imgur.com/gallery/9AzmE
12:33 AM rue_: heh
12:34 AM rue_: I think when trump finishes term, he's gonna sue the usa for defacement of image
12:35 AM katsmeow: hopefully, the usa can quit trump before tehre's a nuke war
12:36 AM katsmeow: Russia kills people anywhere they want to, just like usa and isral, and people get pissed
12:36 AM katsmeow: iran works on a uke, so today Saudi Arabia says if iran makes one, they'll buy some too
12:38 AM zhanx: Saudi Arabia has a treaty with Pakistan to buy the nukes from them
12:38 AM rue_: the cheese stuck to two things
12:38 AM rue_: the spagetti pot, and the cheeese
12:39 AM zhanx: i didn't realize radio shack closed
12:39 AM rue_: rlly?
12:39 AM rue_: you didn't hear that whole long drawn out verbose death?
12:39 AM zhanx: yep the all the stores in my area are closed now
12:39 AM zhanx: no, i missed it
12:39 AM katsmeow: a lot of stores are closing now, partially or totally, thanks Trump
12:39 AM rue_: prolly have been for like 3 yeras z
12:40 AM rue_: (rs)
12:40 AM zhanx: no i was at a radio shack last year i know it
12:40 AM zhanx: i got the receipt
12:40 AM rue_: it gradually went downhill after they abandoned their hobbyists
12:40 AM rue_: they COULD have been digitkey
12:40 AM zhanx: I took it to get the same parts
12:41 AM rue_: rs could be digitkey+mouser
12:41 AM rue_: wtf is that t comming from
12:41 AM rue_: (where)
12:41 AM zhanx: they were a mainly cellphone thing and google tells me they died under obama after failing to change to the market but they did pick up arduino at the end
12:41 AM zhanx: but that was too late
12:41 AM katsmeow: mouser costs too much
12:42 AM rue_: latley the w in my wtf has become generic for who/what/where/why/when
12:42 AM katsmeow: self repair : https://imgur.com/gallery/dcSXx
12:42 AM rue_: zhanx, it was way too late
12:42 AM zhanx: most likely
12:42 AM rue_: even by '85 most of the electronics was gutted
12:43 AM zhanx: i know as a kid they were pricey but had the stuff i needed
12:43 AM rue_: if they had kept doing parts, digikey and mouser wouldn't have had room to start up
12:43 AM rue_: kat oof!, nice suit!
12:43 AM zhanx: trust me i was confused, walking in to the store, it a TSC now, never read the sign outside
12:44 AM rue_: I might just use a bike suit for me
12:44 AM rue_: when I'm a robot
12:44 AM rue_: I'm not sute
12:44 AM rue_: sure
12:45 AM zhanx: one day you might be able to decide
12:46 AM katsmeow: TSC has pulleys, hydraulic pistons, etc
12:47 AM zhanx: true but not 6v dc motors and caps
12:50 AM katsmeow: small engine starter motors?
12:50 AM zhanx: way too large
12:50 AM zhanx: fan for the dehydrator
12:50 AM zhanx: motor died on it again
12:50 AM zhanx: buddy had a deer jump in front of his plow truck and not jump back far enough so i got 90 pounds of meat to make jerky
12:50 AM * katsmeow looks at rue's pileof motors and her pile of fans from nukeboxes
12:50 AM zhanx: my sister freaked cause i was skinning "road kill" he brought over with the tag as he was too busy to clean and dress it
12:51 AM katsmeow: 90 lbs is a lot of jerky, why not make some steaks and burgers?
12:52 AM zhanx: i own him half, and i got venison still but some will be steaks
12:54 AM rue_: ok, if I'm lucky that spagetti will stay below my esophogus
12:54 AM * katsmeow shuts down Tiggr5 and gives the laptop somethingto chew on for 20 hrs
12:55 AM katsmeow: rule of making spagetti move : put layer of whole kernal corn on top, cover corn with black pepper tilly ou canot see the corn any ore, stir in completely
12:58 AM katsmeow: AARRGG< i forgot something on Tiggr5
12:58 AM katsmeow: i hope there's room
12:59 AM katsmeow: there's not
01:02 AM katsmeow: must it be a 6v fan and not 120vac ?
01:02 AM zhanx: t = 1/K * ln(Ts - Tf/0- Tf) computational fluid dynamics sucks
01:02 AM katsmeow: last years sale on "personal fans"
01:03 AM rue_: zhanx, is one of those t's temperature?
01:03 AM zhanx: yes
01:03 AM rue_: and do you REALLY know the K for your material
01:04 AM zhanx: that is the problem
01:04 AM zhanx: 212 degress hot liquid, 50 copper coil
01:05 AM zhanx: 5 gpm pump with 68 degree water
01:05 AM zhanx: real world time was 31 minutes but the math doesn't support it
01:06 AM katsmeow: 212 degrees of H2SO4 is really going to do a number on the copper coil, so i don;t think the math is worth it
01:09 AM rue_: ssrry, I cant context out the system from that data
01:10 AM rue_: kat, I really want to make progress on the mecha this year
01:10 AM rue_: atleast one working arm
01:11 AM rue_: I need to pull off projects faster
01:11 AM rue_: I have a few software projects that have lapped this year already
01:11 AM rue_: I have to binge to get them done tho, and I cant with a job and a body that needs sleep
01:11 AM katsmeow: you need to spec the parts needed and throw more money into getting them?
01:11 AM rue_: I have a bunch of parts
01:12 AM rue_: maybe enough for an arm
01:12 AM rue_: I got the engine last fall
01:12 AM rue_: I have the compressors
01:12 AM rue_: so I should be able to do the power pack
01:12 AM rue_: most of the design shortfall is the force feedback for the controller
01:13 AM rue_: I had to make the robot 12' big to make it
01:13 AM rue_: I cant just scale up for the force feedback control
01:13 AM rue_: but I have an actuator idea
01:14 AM rue_: 'take an extension ladder, fix one end and start twisting the second end' it gets shorter
01:14 AM rue_: a rope ladder with ridgid rungs
01:14 AM katsmeow: i think i have seen the aluminum blocks for measurng pressure somewhere
01:14 AM zhanx: rue found my issue
01:14 AM rue_: if I use dc motors, I can go by current
01:14 AM rue_: zhanx, ok
01:14 AM rue_: wrong units?
01:15 AM rue_: supposed to be in kelvin?
01:15 AM zhanx: gravity of the water with stuff in it is higher than regular water
01:15 AM zhanx: so the density is off
01:15 AM rue_: depending on the stuff
01:15 AM zhanx: sugars
01:15 AM katsmeow: styrofoam and pumice islighter
01:15 AM rue_: zhanx, you dont have a SG tester for batteries?
01:15 AM rue_: or coolant?
01:16 AM zhanx: yea but never than to use it for sugar in water
01:16 AM rue_: sg is sg
01:16 AM zhanx: thought*
01:16 AM katsmeow: how will you melt sugar in water? wonl;t you need apressure vessel ?
01:16 AM rue_: 1.1 is 10% higher than the sg of water
01:16 AM rue_: k
01:17 AM rue_: kat, other ratio?
01:17 AM zhanx: kat depends on the temps. after a certain temp the water will expel the sugar
01:17 AM katsmeow: as in the water will evaporate (boilingly)
01:17 AM rue_: you making a coolant system or moonshine?
01:17 AM zhanx: both
01:17 AM rue_: haha
01:18 AM zhanx: no a greenhouse heater
01:18 AM rue_: k
01:18 AM rue_: not just using auto. glycol antifreeze?
01:19 AM zhanx: in case it leaks
01:19 AM rue_: its all env.friendly now
01:19 AM rue_: isn't it?
01:19 AM zhanx: but not cheap
01:19 AM rue_: ok
01:19 AM rue_: liquid hydrogen has a great heat capacity ya know
01:19 AM rue_: better than water
01:19 AM katsmeow: Melting point None; decomposes at 186 °C (367 °F; 459 K) <<-- if sugar has no melting point, how do they make caramel?
01:20 AM rue_: good question
01:20 AM rue_: hey, I could make a sugar printer
01:20 AM zhanx: or Belgium candy?
01:20 AM katsmeow: or rocket fuel : Sucrose does not melt at high temperatures. Instead, it decomposes—at 186 °C (367 °F)—to form caramel. Like other carbohydrates, it combusts to carbon dioxide and water. Mixing sucrose with the oxidizer potassium nitrate produces the fuel known as rocket candy that is used to propel amateur rocket motors.
01:20 AM rue_: C12H22O11
01:21 AM rue_: geez, that stuff should have a flamability warning
01:21 AM zhanx: great my green house is gonna be rocket powered
01:21 AM zhanx: all cause i am cheap
01:21 AM rue_: zhanx, is propane usable as a refrigerant?
01:21 AM zhanx: it is yes
01:22 AM katsmeow: yeas
01:22 AM katsmeow: r522 ?
01:22 AM katsmeow: 509?
01:22 AM zhanx: not recommended anymore
01:22 AM katsmeow: i forgets
01:22 AM zhanx: 509
01:22 AM rue_: google says the melting point of sugar is 186c, then goes on to say
01:22 AM rue_: https://www.huffingtonpost.com/2011/07/26/sugar-melting_n_909712.html
01:23 AM zhanx: i think water is r573 or something like that as a refrigerant
01:23 AM katsmeow: after stirring the stuff on a hot stove, most people will say it melts just fine
01:23 AM zhanx: i melt sugar without water so i would agree
01:24 AM zhanx: but i don't know the temp sugar becomes a vapor
01:24 AM rue_: prolly more than your compressor will handle
01:28 AM katsmeow: when you lite it at the bottom of the rocket
01:28 AM katsmeow: <coff> sugar and calcium carbonate making fake fulgerites </coff>
01:28 AM rue_: so, you can melt sugar at any temperature
01:28 AM rue_: cause its not melting
01:28 AM * rue_ thinks about this
01:28 AM katsmeow: not melting, just becomes a sticky thick liquid
01:28 AM zhanx: well it changes state of matter
01:28 AM rue_: "dont try to follow the rules, do what the rules dont say you cant do"
01:28 AM zhanx: not
01:28 AM zhanx: i got 50 feet of 1/2 copper line
01:28 AM zhanx: tested a mock up tonight on it
01:28 AM katsmeow: here;s a hammer
01:28 AM zhanx: no i break stuff with a hammer
01:28 AM zhanx: theory is
01:28 AM zhanx: 25 feet down and back in the ground. sugar as the coolant heat the green house
01:28 AM katsmeow: theory is.. we do not agree with your imperical evidence
01:28 AM zhanx: nope neither do i
01:28 AM katsmeow: 50ft is not enough
01:28 AM katsmeow: most high btu geothermal aren;t even closed loop
01:29 AM zhanx: i got bed rock at 50 ft tho
01:29 AM katsmeow: you have a danger of making quicksand
01:29 AM zhanx: closed loop for this
01:29 AM zhanx: i know its not proper
01:30 AM zhanx: but its a 8x16 foot green house
01:30 AM katsmeow: i suspect you need to be talking 1000's of feet buried
01:30 AM katsmeow: got permafrost?
01:31 AM zhanx: i am thinking 2" soft line 2500 feet min for 60 degrees but i want not to freeze is all
01:31 AM zhanx: yep
01:31 AM katsmeow: ouch
01:31 AM zhanx: 42" is permafrost line here
01:31 AM katsmeow: going to be hard to siphon heat outs ice
01:31 AM katsmeow: outa
01:31 AM zhanx: yep
01:32 AM katsmeow: solar with woodchip backup?
01:32 AM katsmeow: tons (literally) of insulation?
01:32 AM zhanx: solar alarm, wood stove
01:32 AM zhanx: work in progress
01:33 AM katsmeow: waste oil
01:34 AM zhanx: double wall green house outside will be 9x17 inside 8x16
01:34 AM zhanx: compost and wood stove to get it to temp
01:34 AM zhanx: thermal well to help keep it there
01:34 AM katsmeow: north side has no sun, bury the north side in a huge pile of compost
01:34 AM zhanx: i get wood for free
01:34 AM zhanx: well wood chips
01:34 AM katsmeow: copost rotting makes heat
01:35 AM zhanx: yep
01:35 AM zhanx: landlord is still in the air on the wall of compost
01:35 AM katsmeow: why ?
01:35 AM zhanx: looks
01:36 AM katsmeow: space off the greenhouse 3ft, build a pretty wall, put chips etc tween wall and greenouse
01:37 AM rue_: composting != rotting
01:37 AM katsmeow: in spring, open trap door at bottom, shovel out rotted compost
01:37 AM katsmeow: rue, it's close
01:37 AM zhanx: not far off from rotting
01:37 AM zhanx: its making dirt
01:37 AM zhanx: which we are all older than
01:42 AM * katsmeow wavers gnites
01:42 AM rue_: oh god its almost midnight
01:42 AM rue_: howd that happen
11:58 AM Tom_itx is now known as Tom_L
09:27 PM katsmeow: plastic bottle are typically blow-molded, how do i re-blow a 2L bottle?
09:28 PM rue_bed: microwave
09:28 PM rue_bed: use plastic adapters tho
09:28 PM katsmeow: but they don;t warm in a microwave
09:28 PM rue_bed: no, but water in them will
09:28 PM katsmeow: oh
09:29 PM katsmeow: same as "start with hot water"?
09:29 PM rue_bed: I boiled a bottle damn near down to its origional tube once
09:29 PM rue_bed: kat, your trick to wake up only works sometimes
09:30 PM * katsmeow is debatingmaking them rectangles
09:30 PM katsmeow: the wake up trick?
09:30 PM katsmeow: pepper and corn is less about waking up and more about regular pooping
09:31 PM katsmeow: need more protien and less carbs to go with pepper to wake up
09:32 PM katsmeow: humans are jacking up the prices of parts on ebay much higher than they were 10 yrs ago
09:35 PM katsmeow: https://duckduckgo.com/?q=pollibricks&t=ffsb&iax=images&ia=images#
09:41 PM katsmeow: http://s3files.core77.com/blog/images/2012/10/BottleBrick-Rendering1.jpg
09:42 PM katsmeow: the mold : http://s3files.core77.com/blog/images/2012/10/BottleBrick-MoldClosed.JPG , a cnc'd cherrywood pour mold
09:43 PM katsmeow: the insides : http://s3files.core77.com/blog/images/2012/10/BottleBrick-MoldOpen.JPG
09:44 PM katsmeow: http://s3files.core77.com/blog/images/2012/10/BottleBrick-SmokingKills.jpg <-- You know what they say—Where there's smoke, there's a cherrywood glass mold expelling moisture.
09:49 PM Tom_L: or a still
09:53 PM katsmeow: https://en.wikipedia.org/wiki/Bottle_wall
09:54 PM Tom_L: rue_, how deep a cut do you take with your 1/8" cutter
10:47 PM Tom_L: ok this post is working nice
10:48 PM Tom_L: i can put OP stops in with user comments, change work positions etc all in one file
10:48 PM Tom_L: wonder why i didn't do this years ago
10:50 PM * katsmeow does not know
10:50 PM katsmeow: use rue's time machine to go back and ask?
11:05 PM katsmeow: so, seems like to make a audio sound foreign, record the amplitude envelope, then reverse the audio, so they talk backwards, and impose the original un-reversed amplitude envelope on it
11:40 PM rue_: we dont know yet
11:40 PM rue_: we just came across another difference in the cans that causing problems
11:40 PM katsmeow: cans?
11:41 PM rue_: paint cans
11:41 PM rue_: the top on the series were making sprayers for is horrid
11:41 PM rue_: http://www.ruemohr.org/
11:41 PM rue_: 1 horrid webpage
11:42 PM rue_: we just went and sent out 4 6" ones without takeing pictures
11:43 PM rue_: *sigh*
11:43 PM rue_: I'm going to have a bath and try to work out how to take over the world
11:43 PM rue_: usally dont do that, making I'm getting ill again
11:44 PM katsmeow: is the world worth it, and do they deserve you?
11:54 PM ^kat^: erg
11:56 PM ^kat^: what's "origional " ?
