05:52 PM Tom_L: https://grabcad.com/library/hard-drive-adapter-1
06:27 PM rue_: heh, I needed a download and print
06:28 PM rue_: I dont like that one, I want to design my own
06:29 PM rue_: the thingiverse one, dont like..
06:29 PM rue_: in "a few years" all hd's will be ssd 'on board'
06:30 PM rue_: clip-in at first, then just built in
06:31 PM rue_: size of storage will get smaller, people will reminis about the days of having 6Tb in a machine
06:31 PM rue_: sata will live a long time as a way of adding extra space to a machine
06:32 PM rue_: pcie will do strange things
06:50 PM Tom_L: i have an onboard ssd
06:50 PM Tom_L: in a box on a shelf waiting for a box to put it in
07:31 PM rue_shop3: hmm
07:32 PM Tom_L: https://www.youtube.com/watch?v=sFXniBbgbw0
08:41 PM katsmeow: <coff>
08:49 PM Tom_L: https://www.youtube.com/watch?v=sFXniBbgbw0
08:49 PM katsmeow: hmm?
08:51 PM katsmeow: what is the video?
08:51 PM Tom_itx: cnc welding
08:52 PM * katsmeow moves it to the laptop for viewing
08:53 PM katsmeow: it's offline, be aminute
08:54 PM Tom_itx: not that exciting
08:56 PM katsmeow: you going to put a wirefeed on the mill to add metal instead of removing it?
08:56 PM Tom_itx: no
09:01 PM katsmeow: doing donuts with a xy table under the wirefeed gun seems like a pricey way to make pipe
09:01 PM Tom_itx: unless you have hundreds to do
09:05 PM katsmeow: i like his humor
09:08 PM Tom_itx: i had no volume while viewing
09:09 PM katsmeow: in this case, you should get some volume
09:11 PM katsmeow: "if you do your drilling and tapping with your eyes closed, you get that nice HarborFreight look."
09:15 PM katsmeow: btw, no need to drill holes in the uprights to make a hydraulic press
09:15 PM katsmeow: or slots
09:15 PM katsmeow: the point is to hold the table up,,,, so stick a railroad tie under the table
09:16 PM katsmeow: or some steel
09:18 PM Tom_itx: yeah if you have the right size handy
09:19 PM katsmeow: you'll never have the holes drilled in the rightplace either
09:19 PM katsmeow: plus, drilling hols removes the material you are counting on for strength
09:19 PM Tom_itx: in theory you would have them placed within the stroke limits of the cylinder
09:20 PM Tom_itx: you can stress test material with holes as well as without
09:21 PM katsmeow: but why botehr drilling holes and using pins, when it's easier using assorted steel hold-up blocks?
09:21 PM Tom_itx: either is workable
09:22 PM rue_shop3: hi!
09:23 PM * katsmeow ponders using hydraulic jacks under the table of the press, to position the table
09:23 PM katsmeow: hie rue
09:23 PM rue_shop3: well, I finally did it
09:23 PM rue_shop3: I changed the fish water
09:24 PM * katsmeow has no fish water,, what do you use it for?
09:24 PM rue_shop3: containing the fish infestation in my kitchen
09:25 PM katsmeow: ah,, you cover the fish in it so they aren't flopping around the table, getting in the way?
09:25 PM rue_shop3: floor, yes
09:26 PM katsmeow: but won;t that alsomake it difficult for the cats to eat the fish?
09:26 PM Tom_itx: cat food
09:26 PM rue_shop3: the water keeps the two apart
09:26 PM katsmeow: that's what i said
09:29 PM rue_shop3: yes, but I think you meant it differently :)
09:29 PM katsmeow: well, diferent pov
09:33 PM rue_shop3: any progress on the brake?
09:34 PM katsmeow: yeas
09:34 PM katsmeow: no pics tho
09:34 PM rue_shop3: ok
09:34 PM katsmeow: cut some steel, burned a few sticks of 7018 on it today
09:35 PM katsmeow: might haveto regrind the hold-down edge again due to heat warping
09:35 PM rue_shop3: :) your so good you could just counterwarp it
09:36 PM rue_shop3: whatevers less headache tho I suppose
09:36 PM katsmeow: re-designing the x-y hold-down positioning as i go, to allow for usng a different holdown to make boxes
09:36 PM rue_shop3: yes, I want to see the final design!
09:39 PM rue_shop3: so
09:39 PM rue_shop3: the heated bed for the printer runs about 10-12A
09:39 PM rue_shop3: I'm using AC direct off a transformer
09:39 PM rue_shop3: (opposed to the regulated 12V the rest of the world is using)
09:40 PM rue_shop3: SO, I currently have the triac on the low voltage side
09:40 PM katsmeow: why are you heating the bed?
09:40 PM rue_shop3: ABS shrinks so badly you have to
09:40 PM rue_shop3: or it warps off as you print
09:40 PM katsmeow: err, i'd put the triac on the high side, it will run cooler, less amperage there
09:41 PM rue_shop3: I think I should be switching the high voltage side tho
09:41 PM rue_shop3: yea
09:41 PM rue_shop3: 1A instead of 10-12
09:41 PM katsmeow: yeas
09:42 PM rue_shop3: you familiar with the 'ant and the grasshopper'?
09:43 PM katsmeow: yeas
09:44 PM rue_shop3: I think the ant was being a racist bastard, kinda
09:45 PM rue_shop3: if no grasshopper EVER lived thru the winter, how could it possibly be schooled in living thru one?
09:46 PM rue_shop3: and if one did, the new generation would never see it "yea, well I'm old too!"
09:47 PM * katsmeow tends to not believe any fairey tales
09:47 PM katsmeow: or fables
09:48 PM katsmeow: it's like the bible, Adam and Eve had two boys,, who did they have children by? baaaddd fable
09:49 PM Tom_L: through history alot of women have been left out
09:49 PM * katsmeow nods
09:50 PM rue_shop3: "this is what happened to the generations before me, this is what will happen to me"
09:50 PM rue_shop3: kat, yes :)
09:51 PM katsmeow: Tom, so if Adam and Eve had some girls too,,,,,,,,,,,,,, it's still incest
09:51 PM Tom_L: i'm guessing the gene pool was fairly pure at that point
09:52 PM katsmeow: pure?
09:52 PM katsmeow: so the babies from incest would be almost clones?
09:53 PM rue_shop3: maybe the ground was highly radioactive (everything had just been created, right?) and there was a lot of gene varriance :)
09:53 PM katsmeow: anyhow, beware of people making up simple fable to try and sway you, it's no different than advertising on tv
09:54 PM rue_shop3: my direction was about living thru death
09:54 PM rue_shop3: and us being in the grasshoppers shoes
09:57 PM rue_shop3: hmm
09:57 PM rue_shop3: this wont work
09:58 PM rue_shop3: I have both legs of the transformer going into the triac
09:58 PM katsmeow: you should not
09:58 PM rue_shop3: tidy tho
09:59 PM * katsmeow hands rue a normal household light dimmer to control the transformer
09:59 PM rue_shop3: ardui o is doing it
10:00 PM * katsmeow sends rue a n
10:01 PM rue_shop3: huh, look, I even found a space to put it in...
10:04 PM * katsmeow juggles various things in her head
10:04 PM rue_shop3: I'm still waiting for a reply...
10:05 PM rue_shop3: is the thread still active?
10:05 PM katsmeow: shure, but was there a question ?
10:06 PM rue_shop3: <rue_shop3> my direction was about living thru death
10:06 PM rue_shop3: <rue_shop3> and us being in the grasshoppers shoes
10:06 PM katsmeow: see, no question
10:06 PM katsmeow: about it,
10:06 PM katsmeow: there's no question
10:06 PM rue_shop3: white and purple, purple should be + right?
10:06 PM katsmeow: ok
10:08 PM rue_shop3: do all answers need questions? that kinda limits us, dosn't it?
10:08 PM * katsmeow ponders pasta plus prepared side dish packet of pasta and broccoli and chicken plus a tastey ground pepper
10:10 PM * rue_shop3 contemplates nothingness
10:10 PM katsmeow: one might be concerned the ant is exhibiting signs of .......... psychpathology , in telling the starving grasshopper to go dance away the winter too
10:10 PM katsmeow: psychOpathology
10:10 PM katsmeow: as in, haveing zero empathy
10:13 PM katsmeow: https://en.wikipedia.org/wiki/The_Ant_and_the_Grasshopper#Fable_and_counter-fable
10:13 PM katsmeow: https://en.wikipedia.org/wiki/The_Ant_and_the_Grasshopper#Moral_and_artistic_debate
10:16 PM katsmeow: but more to your point, i still say you cannotput yourself into a machine, but it might be possible to make a good nuff copy of your functions in a machine
10:16 PM katsmeow: but it won;t be you, even if you are killed in the process
10:17 PM rue_shop3: I regard it like trying to take an app for a mac, and, without the source code, trying to get it to run on an intel
10:18 PM rue_shop3: (non-intel mac assumed)
10:18 PM katsmeow: the machine will have hard- or soft-coded responces to stimuli, which would override anything your spirit would intend, and this woldmake it more appealing to you to live in a rodent's body than the robot's body
10:19 PM katsmeow: i think you are a human to expereince the sensory input, which the machine lacks
10:20 PM rue_shop3: :) so far, the triac module, the heater, and the transformer have not burst into fire
10:20 PM katsmeow: good, the triac is not rated at 32v
10:20 PM rue_shop3: its rated down to 24
10:20 PM rue_shop3: but the secondary is 18
10:20 PM katsmeow: down to? there;s a lower limit on triacs?
10:21 PM katsmeow: it's a pnpn device, shold be good down to 3v
10:21 PM katsmeow: or, maybe it's an npnp device
10:22 PM katsmeow: it's a 2n3055 and a 2n2955 intertwined collector-to-base
10:27 PM rue_shop3: its a regualr triac on a huge heatsink
10:27 PM katsmeow: ok
10:28 PM * katsmeow hooked wall-type dimmers to big stud-mount triacs to operate big-arsed 2kw spots and banks of floods
10:29 PM katsmeow: but that was in high school when i didn;lt know that's impossible
10:29 PM rue_shop3: I had a peice of glass I was trying to cut today and it saw I wasn't 100% confident, and it broke wrong
10:30 PM rue_shop3: I has it really well scored and everything
10:31 PM katsmeow: needs a really straigh and level edge to break it over
10:32 PM katsmeow: afk to make a byte to eat, brb
10:32 PM katsmeow: and get these steeltoad boots arff
10:34 PM rue_shop3: oh yea, my rice must be ready now
10:39 PM rue_shop3: hmm, the heater is running a duty of about 1%
10:39 PM rue_shop3: to keep the table at 60c
10:40 PM katsmeow: bak
10:41 PM katsmeow: 1% is awefully low
10:41 PM katsmeow: but the lower it is, the less it overheats the shop in summer
10:54 PM katsmeow: additives addified
10:54 PM katsmeow: the addificatory process went smoothly
11:06 PM * katsmeow waits on it to kool arf
11:08 PM * katsmeow has some naked srams, 32k x 8 , need dip smd packaging, got any? oh, and a die wirer
11:12 PM katsmeow: whacha think about putting 10 panels of 17v each in series, and feeding the 170vdc into regular 120vac-14vdc switchers?
11:16 PM katsmeow: put the ouputs in series, like to 48v, 60v, etc
11:18 PM rue_shop3: scarry voltages!
11:19 PM katsmeow: hmm?
11:19 PM rue_shop3: string inverter solar arrays go up to 600VDC
11:19 PM rue_shop3: THATS REALLY scarry
11:19 PM katsmeow: too high
11:22 PM katsmeow: moving 170vdc (same as the peak of 120vac) @ 5amps beats trying to move 12vdc @ 70amps
11:23 PM katsmeow: and easier to switcher 48vdc battery bank to 120vac, etc
11:48 PM katsmeow: Lindsey Sterling has over 700 million views on yt
11:49 PM rue_shop3: who?
11:49 PM katsmeow: that woman,, you know,, her name, on youtube
11:49 PM rue_shop3: so, to keep the printer at 110c, it like, 90% duty
11:50 PM katsmeow: to cook eggs?
11:50 PM rue_shop3: ABS
11:51 PM katsmeow: smoked ABS, i see
11:51 PM rue_shop3: the extruder temp is 242c
11:52 PM katsmeow: have you tried extruding scrambled eggs to make a new kinda "pasta" ?
11:53 PM katsmeow: hmmm @ stepper motors playing a violin
11:57 PM * katsmeow ponders rue's robot arm writing a book
11:58 PM * rue_shop3 ponders trying to get the robot arm to hit enter so the plotter can write the book
