12:59 AM CaptHindsight: Kernel 4.19 now working with RTAI
02:18 AM Deejay: moin
03:00 AM rmu|w: does anybody know how this https://www.fujitsu.com/de/products/computing/peripheral/mainboards/industrial-mainboards/d3544s.html motherboard behaves under rt preempt?
03:27 AM andi_: is the linux-cnc capable of doing a chained threadcut? i need to chain two G33 to change the thread pitch without a stop after the first g33 (no freecut)
03:30 AM grandixximo: S100 M3 (start spindle turning)
03:31 AM grandixximo: G33 Z-4 K0.05
03:31 AM grandixximo: if you do something like that it stops?
03:31 AM andi_: well that's a regular G33
03:32 AM grandixximo: but have two consecutive G33 with different pitch
03:33 AM andi_: well pitch could be the same, but could also be different
03:33 AM andi_: i want to go from a regular thread into a taper thread for example
03:34 AM andi_: So G33 Z-4; G33 Z-4 X+2 (relative)
03:35 AM grandixximo: so in G91
03:35 AM andi_: yeah well G90/G91 does not matter i could also programm in absolut coords
03:36 AM grandixximo: G91
03:36 AM grandixximo: what this does?
03:37 AM grandixximo: there is a stop between the two G33?
03:37 AM andi_: yeah
03:37 AM andi_: i need a G61 so there won't be a sto
03:37 AM andi_: p
03:38 AM grandixximo: what if you set G64 P0.01
03:39 AM grandixximo: or maybe bigger if you are in mm
03:40 AM andi_: what does the G64 actually do?
03:40 AM grandixximo: http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g64
03:41 AM grandixximo: in changes the path so that it keeps going, don't know if it will work with G33, i never used G33 '=D
03:42 AM andi_: hmm that would be worth a test
03:42 AM andi_: problem is not if it works, that's probably working bit is the thread useable
03:45 AM grandixximo: i think if you want interolate with accuracy you may want to make a special config where your spindle is controlled like a third A axis, you can have perfect control over the interpolation, it would take more to write the gcode but you'd get better results IMO, but i maybe just talking out of my butt since i never use a lather CNC X)
03:46 AM andi_: well let's tinker a bit around :)
03:47 AM grandixximo: a fourth axis sorry
03:47 AM grandixximo: joint 3 axis A
03:57 AM grandixximo: Anyone interested in coding S-curve acceleration please let me know
03:57 AM grandixximo: 8)
03:57 AM sensille: grandixximo: i am, but not for linuxcnc ;) (also, i haven't read the backlog)
03:57 AM grandixximo: Where would you be coding S-curve?
03:57 AM grandixximo: Gerbl?
04:01 AM grandixximo: how long do you think to finish it?
04:04 AM XXCoder: hey pink_vampire whats up
04:04 AM grandixximo: will it work on master CNC?
04:05 AM rmu|w: grandixximo: no time to work on it at the moment
04:05 AM XXCoder: @pink_vampire: the one and only heh
04:05 AM rmu|w: grandixximo: but you can try it and get an idea what could be a way where to implement it
04:06 AM grandixximo: rmu|w i'd like to hire someone to finish it
04:06 AM rmu|w: grandixximo: unsolved problems in this concept are * changing feed override while motion is ongoing
04:06 AM rmu|w: * spindle synchronies motion
04:07 AM rmu|w: and of course there are "bugs" and/or interactions with the TP i don't understand that lead to violation of acceleration constraints in some cases
04:07 AM grandixximo: but the smoothness is not delayed, it doesn't happen after path calculation, but in path calculation correct?
04:08 AM rmu|w: no it has nothing to do with path calculation
04:08 AM rmu|w: path calculation in a way is fixed by your g-code and G64 P setting
04:09 AM rmu|w: there is not that much wiggle room AFAIU
04:09 AM grandixximo: Yes i mean it will still respect G64 to some extent?
04:09 AM rmu|w: yes
04:09 AM grandixximo: so it
04:09 AM rmu|w: paths should be identical to what linuxcnc is doing now
04:10 AM grandixximo: Close to identical
04:10 AM grandixximo: when you blend the acceleration you change the position
04:11 AM rmu|w: the theoretical path that is controlled is the same, but speeds and accelerations are different
04:12 AM grandixximo: and you will see the real path take in the Axis preview?
04:12 AM grandixximo: in yellow
04:12 AM rmu|w: if you look at the diff you will see that only acceleration and speed of execution of motion is changed, nothing else
04:13 AM rmu|w: i'm not saying that this solution is finished or makes much sense as it is, just wanted to give a starting point
04:14 AM rmu|w: linear moves from standstill to standstill work quite well, everything else, all bets are off ;)
04:14 AM rmu|w: gotta go
04:14 AM rmu|w: will be back in 2-3 hrs
04:16 AM grandixximo: rmu|w ok talk to you again, i'd really like to have what you made implemented and finished on master, i'm willing to hire someone that gets it to finish it, i have no time or capacity to do it, although i know what i want to be done, and i'm willing to pay for the time
05:29 AM jthornton: morning
05:31 AM XXCoder: hey jt
05:31 AM XXCoder: just worked my last normal shift today
05:40 AM jthornton: starting short shifts?
05:40 AM XXCoder: yeah
05:41 AM XXCoder: i have no idea what breaks times is lol
05:41 AM jthornton: I have a fence to build but I'm putting it off for a while
05:41 AM XXCoder: hey fence makes good neighbors ;)
05:42 AM jthornton: it's a fence to keep the guys grand kids from having access to the pool
05:42 AM jthornton: I built the fence around his pool too and that was very fun two walls were tapered
05:43 AM * SpeedEvil imagines bluing up the wall to accurately fit the fence.
05:43 AM jthornton: imagine a lot of measuring and cad work
05:44 AM XXCoder: cool :)
05:48 AM rmu|w: grandixximo: i think you should talk to rob ellenberg
06:01 AM rmu|w: hehe ö1 live schaltung in die antarktis
06:01 AM rmu|w: das latenzt merkbar
06:04 AM rmu|w: sorry
06:04 AM rmu|w: wrong #
06:14 AM grandixximo: rmu|w thanks, i wrote him an email...
06:25 AM grandixximo: Is Rob Ellenberg the one that coded the trajectory planner?
06:25 AM rmu|w: yes
06:28 AM grandixximo: Great thank you!
06:43 AM jymmmm: Toss inflatable bobo the clown punching bags into the pool, that should scare the shit out of the kids and keep em safe
06:49 AM jymmmm: jthornton: Plant a giant mutant brocolli fence around the pool, that should scare em enough to keep away from the pool =)
06:50 AM XXCoder: https://s3.crackedcdn.com/phpimages/article/6/6/4/723664_v3.jpg its scent thing, but I know what its real use for. Top contain General Zod and his minions.
06:51 AM XXCoder: *to
06:58 AM jymmmm: How soft is 99.99% pure magnesium?
07:26 AM Tom_L: morning
07:50 AM jymmmm: Tom_L morning
08:19 AM grandixximo: rmu|w: what would be the best way to reach Robert?
08:21 AM rmu|w: grandixximo: I don't know the best way, in fact, I don't have any contact info besides what google would output
08:22 AM grandixximo: I see, I think I already tried to contact him by email a long time ago, don't remember if I ever got a reply
08:22 AM grandixximo: Thank you
08:38 AM SpeedEvil: The oddest place to put linuxcnc. https://i.imgur.com/tkBhvGF.jpg
08:39 AM rmu|w: a cow rotator?
08:40 AM SpeedEvil: yes
08:43 AM rmu|w: how do you know there is linuxcnc in there?
08:43 AM SpeedEvil: It was a joke.
08:43 AM SpeedEvil: I would be very surprised if there is
08:45 AM rmu|w: the company that is building those is about 25km from here, that's why i'm aksing
08:45 AM rmu|w: aksin
08:45 AM rmu|w: g
08:45 AM rmu|w: grrr
08:45 AM rmu|w: _asking_
08:45 AM SpeedEvil: :) Fun coincidences.
08:45 AM gregcnc: wait I didn't know cows needs turning?
08:46 AM gregcnc: I don't think I've ever seen an example of variable lead threading in linuxcnc
08:46 AM SpeedEvil: Various reasons - trimming hooves, restraining them while working on injuries, ...
08:49 AM rmu|w: combined with a truck-mounted crane you could perform c-sections on cows
08:53 AM gregcnc: i hate going through ebay completed to get a feel for prices only to see exactly what I needed recently almost given away
08:53 AM SpeedEvil: :/
09:05 AM skunkworks: gregcnc: funny you should ask.. https://www.youtube.com/watch?v=ACvRilmIKDQ
09:07 AM gregcnc: pretty sure this is what grandixximo was asking for
09:07 AM skunkworks: I thought he wanted S-curve
09:10 AM grandixximo: It was andi_ that asked for the g33
09:14 AM gregcnc: oh oops
09:15 AM andi_: skunkworks: okay, yeah that looks good
09:16 AM andi_: is there more info about it?
09:20 AM andi_: is this an independent axis?
09:22 AM gregcnc: of course i forgot to search for EMC2 https://www.cnczone.com/forums/general-metalwork-discussion/54204-engineering.html#post422473
09:22 AM gregcnc: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?JMKsFusee
09:23 AM skunkworks: andi_: independent axis?
09:24 AM skunkworks: jmk's site is down but have found it on the internet archive..
09:25 AM skunkworks: gregcnc: I took me 2 tries..
09:26 AM skunkworks: sliptoni`: love your videos :)
09:28 AM gregcnc: I've seen a lot of activity in shop built injection molders. I'm thinking I may want to do one myself.
09:29 AM gregcnc: the screw is one application for this
09:31 AM andi_: skunkworks: how's the sync done between axis?
09:31 AM Kaylah: hello, someone referred me to this channel saying there are many engineers here who design things, but I have a question about structural engineering which doesnt seem to match the topic of the channel very much, is it okay to ask here?
09:31 AM andi_: i don't understand what i need to do
09:32 AM gregcnc: you need an encoder with index on the spindle
09:38 AM skunkworks: G33 doesn
09:38 AM skunkworks: oops
09:39 AM skunkworks: g33 doesn't care how many axis you move in - it will create the sync between them all.
09:39 AM skunkworks: well - up to xyz anyways I think
09:40 AM skunkworks: K is just the distance the segment will move per rev
09:50 AM Tom_L: skunkworks, they should have G33 X Y Z I J K but it's just K so X Y Z would all move the same instead of independently with the spindle
09:50 AM Tom_L: not sure when you would ever need that but...
10:01 AM skunkworks: Don't think I have done a synced move with more than 1 axis.. well - I think I did cut the fusee
10:11 AM gregcnc: Tom_L this is more a lathe thing in terms of threading. the starting and ending X position defines that change in X
10:13 AM gregcnc: with a mill you'd have to have a rotary axis that changes radius like seen on large horizontals to be useful
10:14 AM gregcnc: by rotary I mean spindle
10:19 AM skunkworks: https://youtu.be/P0RP7s-rDsg
10:21 AM gregcnc: That's cool. can the internal features can be done the same way? or is there more to the tool position?
10:22 AM gregcnc: i mean in 2 axis lathe or is Y required for the internal feature
10:24 AM skunkworks: um. you can do the same thing internal on a lathe..
10:25 AM skunkworks: right now - if there was a boring bar - you could cut the same shape internally
10:25 AM skunkworks: like what andy did with his lathe
12:52 PM rmu|w: is there a reason there is "Qtvcp" and "QtPyVcp" category in the forum?
12:52 PM rmu|w: what is the difference?
12:56 PM jthornton: two different GUI's
12:57 PM jthornton: QtPyVCP is coded different with different options and methods
12:57 PM jthornton: with QtPyVCP you can start with a blank slate and build a GUI just the way YOU want it
12:58 PM jthornton: http://www.qtpyvcp.com/
12:58 PM * jthornton goes back to the big shop
12:58 PM Tom_L: Qtvcp is older
12:58 PM Tom_L: jthornton, try the trick?
01:03 PM JT-Shop: not yet
02:02 PM Loetmichel: *hehe* just played a bit of "cardlife"... funny how those "tardis" inventorys work in those games... you can carry 20*99 pcs of stone. enough to buld a very big mansion... but your backpak on the avatar is maybe 5 gallon ;)
02:03 PM andypugh: Did you ever play the Hitchikers Guide to the Galaxy text adventure game?
02:03 PM andypugh: That played with that concept.
02:03 PM Loetmichel: nope
02:04 PM andypugh: https://www.bbc.co.uk/programmes/articles/1g84m0sXpnNCv84GpN2PLZG/the-game-30th-anniversary-edition
02:20 PM jdh: one of the first games I played
02:27 PM andypugh: S
02:27 PM andypugh: you can’t go south
02:28 PM andypugh: S
02:28 PM andypugh: No, really, you can’t go South
02:28 PM andypugh: look
02:28 PM andypugh: doors lead Noth, east, west.
02:28 PM andypugh: S
02:29 PM andypugh: OK, you can go south, but it’s terribly dangerous…
02:29 PM andypugh: S
02:29 PM andypugh: You go South. Nothing happens. Maybe it wasn’t so dangerous after all.
02:30 PM Loetmichel: that sounds like classic MUD
02:30 PM andypugh: It used the Infocom engine, but was scripted by Douglas Adams.
02:30 PM andypugh: I had never previously considered that a game might lie to me.
02:31 PM andypugh: So, more Collossal Cave than MUD.
02:32 PM Loetmichel: ah, infocom rings a bell
02:32 PM Loetmichel: yes, i see
02:32 PM Loetmichel: i was just waiting for the "you were eaten by a grue"
02:34 PM andypugh: That was “Rogue”, a fancy game with graphics!
02:37 PM jymmmm: Atari Pong FTW!!!
02:42 PM Rab: I had the original HHGTG game, with the microscopic space fleet, peril-sensitive sunglasses, etc. I was able to play it on a Wang Professional Computer running MS-DOS 2.01, which had a 360K drive. Never made it very far though.
02:47 PM andypugh: I think I played it first on an Amstrad PCW8512
02:48 PM andypugh: Which I have just found used a Z80
02:49 PM andypugh: (for some reason I thught it used an 80186
02:50 PM andypugh: Hmm, the HP100LX used an 80186, so I own an 80186 :-)
02:51 PM andypugh: I finally finished it about 10 years later after a hint from a friend.
02:52 PM andypugh: It turns out that the “thing your aunt gave you that you don’t know what it is” is a bag of holding.
02:53 PM andypugh: And is the only way to carry all the tools, so that you can pass Marvin the tool he needs to open the door on Magrathea.
03:06 PM SpeedEvil: :)
03:36 PM SpeedEvil: https://imgur.com/gallery/n2fZbiV how a car is built.
03:41 PM jymmmm: lol @ SpeedEvil
03:50 PM jymmmm: Kinda cool... al powder, baking soda, and CA glue.... https://youtu.be/7XYPnHODt1E?t=553
04:04 PM Deejay: gn8
04:17 PM unterhaus: I worked with a guy that wrote a flight simulator for the atari 2600. Disappointed I never got to see it
04:18 PM unterhaus: never made it to market, but he said it worked fine
04:18 PM unterhaus: he was my boss, so I had to believe him
04:19 PM andypugh: Ever play “Jet Set Willly”?
04:51 PM XXCoder: jymmmm: there was site tat shows dent sizes on metal bars after being hammered all over. good indiction of strength, but i cant find it
04:52 PM XXCoder: ignots not bars
05:18 PM jymmmm: XXCoder: Ah, ok. Thanks. I was more looking for softness inititally, but after looking at some videos, I'm looking in another direction
05:19 PM XXCoder: cool :)
05:19 PM XXCoder: too bad I cant find hammers ingots pictures :(
05:19 PM XXCoder: theres lots of ingots, copper, iron, etc
05:19 PM XXCoder: all various sizes of dents all over by even hammering, all approx same strength impacts
05:20 PM jymmmm: XXCoder: WAS looking at MG for fire starting (I have a soft rod I bought eons ago), but even after looking at shavings being used (liek swarf) burns too fast
05:20 PM XXCoder: hmm sounds not not compitable
05:20 PM jymmmm: I think mine was an alloy of some kind, works great, but got it at a gun show
05:21 PM XXCoder: wouldnt you need very strong metal for that?
05:21 PM XXCoder: like titanium since seperation engery is so high sparks is very hot
05:21 PM jymmmm: Wanted it easy to shave like the one I have is
05:22 PM jymmmm: but I've given up an all Mg, just too fast
05:22 PM XXCoder: too bad so whats your plans now
05:23 PM jymmmm: Going back to a fire started I made a couple years ago, it's waterproof, lights with one strike in best conditions, just having a difficult time findin the package for it I would like
05:24 PM XXCoder: cool :)
05:25 PM jymmmm: It's basically jute and a special wax blend I came up with, took me a couple of months to get the formula I like down. but it works in any conditions
05:26 PM XXCoder: patent it
05:27 PM jymmmm: That would be $10K+ down the drain,
05:28 PM jymmmm: The things is it could be the best thing in the world, but if it doens't come in a fancy metal "TACTICAL" tin, ppl dont give it a second look
05:28 PM XXCoder: tactical porn
05:28 PM andypugh: I think that the archetypical sparker metal is Indium.
05:28 PM jymmmm: and I'm NOT trying to market towards the hobbests, but their money spends just like anyone elses
05:29 PM andypugh: Though that might have changed now it has got scarce.
05:29 PM Rab: I always feel like "tactical" is begging the question.
05:30 PM Rab: Like, for exactly which tactic do you employ your black anodized keychain bottle opener/beard comb?
05:30 PM SpeedEvil: Indium is soft, nearly inert, and melts at blood temp
05:30 PM SpeedEvil: I don't think it sparks at all
05:31 PM andypugh: Tactical, and you can make it at home: https://www.youtube.com/watch?v=UvCB3_KtSz0
05:31 PM SpeedEvil: I want a strategic torch.
05:32 PM XXCoder: damn
05:33 PM XXCoder: cant find that very funny tactical paid phone minutes thing
05:33 PM andypugh: One funny thing on that video. He bough 20 compasses from China. 2 out of 20 actually pointed north. That’s just so “Cheap from China, ship regardless of function”
05:41 PM andypugh: Also making fun of “tactical” https://www.youtube.com/watch?v=A3amzB_hVUw
05:45 PM XXCoder: damn
05:45 PM XXCoder: thought it was that "tacitcal call" advert funny
05:46 PM XXCoder: FOUND IT!!
05:46 PM XXCoder: https://www.youtube.com/watch?v=cXrLbzNc8cY
05:48 PM rmu|w: andypugh: Fe / Ce alloy
05:49 PM jthornton: XXCoder, got all the pieces milled and cut for the brooder door
05:49 PM XXCoder: nice
05:50 PM jthornton: yea the rail and stile router bits are pretty neat to use
05:50 PM XXCoder: andypugh: watch that video, you'll be groaning by middle of video arrives
05:52 PM andypugh: Not sure that really works outside the US.
05:53 PM _unreal_: Freaking hysterically funny. was watching the local news and they where talking about massive blockages everywhere in the sewage.... they show a photo of the MASS and its nothing but GLOVES and MASKS clearly GLOVES and MASKS. What do they call it sanitary wipes.
05:55 PM jthornton: not to funny here I had to find some alcohol swabs for my wife as she is diabetic and takes a shot daily... finally found a pack at a small drug store
05:55 PM andypugh: I feel like some kind of monster. I am watching the numbers like they are sports results. I can’t help it.
05:56 PM _unreal_: jthornton, any plane vodka is the same
05:56 PM _unreal_: if your looking for a cleaning solution
05:56 PM _unreal_: jthornton, I was a nurse for many years
05:56 PM andypugh: (And it looks like the US is about to take the “lead”)
05:56 PM jthornton: I found them so she is good for the next 100 days
05:56 PM _unreal_: and a med tech dispensing drugs and shots etc...
05:56 PM XXCoder: jt it sucks, but its good you managed to find some
05:56 PM _unreal_: thats good to hear jthornton
05:56 PM XXCoder: my 3 year old 70% ispy is like liquid gold now
05:56 PM XXCoder: and its still useless for me lol
05:57 PM XXCoder: andypugh: about to take lead? we are #1 for while now
05:57 PM jthornton: I have 5 gallons of 99%
05:57 PM XXCoder: near 500k cases
05:57 PM andypugh: Deaths :-(
05:57 PM _unreal_: jthornton, if they are open, dollar stores are a great place to find most of the things the big stores dont have. bleach, paper products, swabs etc...
05:58 PM XXCoder: 18k getting close to 20%
05:58 PM jthornton: we have a bunch of dollar stores here
05:59 PM jthornton: I'm stocked up on TP for sure just need weekly fresh stuff
05:59 PM XXCoder: i have bidet
05:59 PM XXCoder: so tp lasts a LOT longer
05:59 PM * jthornton is amazed how much air is in cheap TP
05:59 PM jthornton: and how little paper
05:59 PM _unreal_: lol XXCoder google returns many websites claiming total world count and all the sites are "current postings" and have very different numbers
06:00 PM andypugh: TP saving tip from China: https://www.youtube.com/watch?v=iRduYc6GWHk
06:00 PM XXCoder: no crap. we have to use one ply due to crappy sewer connection. i sometimes touch my anus though tp paper it rips so easily
06:00 PM XXCoder: nowdays I just use tp to dry by backend
06:01 PM _unreal_: XXCoder, I have not really seen any shortages in the past ? week now for TP products at least not in my area
06:01 PM _unreal_: I went to BJ's last week they were stocked. I know cosco has plenty now
06:01 PM _unreal_: even my local Publix (food market) is stocked
06:02 PM _unreal_: You guys know about this right ? https://www.necn.com/multimedia/us-charges-3-in-alleged-plots-related-to-china/2224377/
06:04 PM _unreal_: Here are the court documents https://www.justice.gov/opa/pr/harvard-university-professor-and-two-chinese-nationals-charged-three-separate-china-related READ closely they talk about his involvement with covid 19
06:06 PM _unreal_: Harvard is screwed
06:10 PM _unreal_: As far as I'm concerned this is a biological attack
06:10 PM andypugh: It looks like simple fraud to me.
06:11 PM andypugh: But, we all interpret things to suit our own prejudices.
06:11 PM _unreal_: true
06:11 PM _unreal_: well look at it liek this
06:13 PM XXCoder: tp thing?
06:14 PM _unreal_: how do you spread something everywhere. hide it in plain site. If I was theorize how someone would be going to spread this virus around. They would most likely put a large glove on. then a thin cotton glove, wet the cotton glove with the covid 19 culture, then put a nitril or latex what ever glove on with 1 or 2 pin holes in it. and just touch common items. that many people touch.
06:14 PM XXCoder: handheld bidet is just meh
06:14 PM XXCoder: i like mine
06:14 PM _unreal_: bidet?
06:14 PM _unreal_: What is a bidet
06:14 PM XXCoder: it comes with crap bidet seat bumpers though
06:14 PM _unreal_: I have no clue what your talking about
06:14 PM XXCoder: all 3 fell off within days lol ordered better ones but it wont arrive for 100 years
06:15 PM _unreal_: XXCoder, so your grand kids are all set?
06:17 PM _unreal_: so as I said hide it in plain site. and what have the state government done. tell everyone to use gloves and mask. MASK sure gloves are useless, and give a false sense of safety
06:17 PM _unreal_: I've watched people digging in purses with gloves on, eating with """ GLOVES """ on....
06:19 PM _unreal_: and shit loads of gloves on the ground in parking lots. little bio bombs. With a nice source of water from sweating in a captive environment, who knows what contaminants. they are perfect petri dish material
06:19 PM _unreal_: good of ya to join us :)
06:19 PM XXCoder: yay
06:20 PM jthornton: XXCoder, mount a hair drier next to the bidet with a foot switch!
06:20 PM XXCoder: lol sounds dangerous'
06:21 PM jthornton: just make sure it's not an industrial heat gun lol
06:21 PM XXCoder: there is more fancy ones that do have hot air
06:22 PM XXCoder: its around $1500 or more, includes everything (including tiolet itself)
06:22 PM jthornton: interesting
06:23 PM XXCoder: not for me lol
06:23 PM XXCoder: i do want whole seat lid version, better design. but not heated water etc stuff no need for that
06:23 PM XXCoder: cold water works just fine
06:25 PM jthornton: cold water doesn't take as long as warm water lol
06:25 PM XXCoder: exactly
06:25 PM XXCoder: the restroom upstairs here takes so long to warm up
06:25 PM andypugh: It’s odd that dry paper has become the norm in the west. The Romans used wet sponges. I think the Koran suggests smooth stones (not that I have read it, could be way off). It isn’t like paper makes a very good job of the task.
06:25 PM XXCoder: no idea either
06:26 PM XXCoder: chaos is what makes life interesting heh (low level chaos that causes culture differences etc not big one)
06:26 PM jthornton: anything is better than a dried corn cob I think
06:27 PM XXCoder: what about leaves heh
06:28 PM jthornton: they are pretty tiny right now lol
06:29 PM andypugh: I have used leaves. I was at a railway station and found, too late, that the box was empty. I was glad it was Autumn. I do the exact same trip every spring too.
06:29 PM XXCoder: fun heh
06:30 PM jthornton: gotta figure out how to adjust my Shimano Deore derailleur
06:31 PM XXCoder: jt i checked stuff and it seems that its pretty hard to get bidet now
06:31 PM XXCoder: glad i ordered quite a bit ago!
06:31 PM jthornton: I'd bet they are all on back order
06:31 PM XXCoder: or shipping delayed like my amazon order. it wont come till may 8th and i ordered last week
06:31 PM andypugh: jthornton: You can download all the manuals from Shimano. They are really good that way.
06:32 PM jthornton: cool, I'll look for them
06:34 PM jthornton: seems I need a part number to get the correct manual
06:34 PM andypugh: You might find that from an eBay search
06:34 PM jthornton: ok thanks
06:35 PM _unreal_: did I tell you guys my spindle motor arrived
06:35 PM _unreal_: https://www.amazon.com/MYSWEETY-Cooled-Spindle-Converter-Collet/dp/B01N1EJEQ1/ref=sr_1_5?dchild=1&keywords=spindle+motor+1.&qid=1586561730&sr=8-5
06:36 PM _unreal_: sitting in my livingroom
06:36 PM andypugh: _unreal_: The slow weak one?
06:36 PM andypugh: :-)
06:36 PM _unreal_: yes the slow 1.5kw weak one
06:36 PM andypugh: Ah, right, you decided against tha 300W / 15000 rpm one?
06:36 PM _unreal_: the super slow .3kw LOL one is still in china prob waiting to be wet wiped before shipping LOL
06:36 PM _unreal_: ?
06:37 PM andypugh: (numbers, why can I remember numbers but not human names?)
06:37 PM _unreal_: I have 2
06:37 PM _unreal_: andypugh, I ordered BOTH MOTORS
06:37 PM _unreal_: one for home and one for work
06:37 PM _unreal_: the 1.5kw is for the big machine I'm building that is sitting in the living room that the late dog destroyed the carpet
06:37 PM jthornton: andypugh, I want to just have a single chain ring in the front, I assume I still need a chain guide?
06:38 PM _unreal_: andypugh, so whats my name :)
06:38 PM _unreal_: LOOL
06:38 PM andypugh: Chain guide?
06:38 PM jthornton: derailer
06:38 PM _unreal_: for a bike?
06:38 PM andypugh: You don’t need a front mech with a single chainwheel.
06:38 PM _unreal_: interesting a 104 year old beat covid
06:38 PM jthornton: I removed the derailer for the front and when I hit rough stuff it bounced down to the smallest chainring
06:38 PM _unreal_: ww2 vet as well and has his mind
06:39 PM andypugh: jthornton: Possibly the chain is too long.
06:39 PM jthornton: ah ok that makes sense
06:39 PM _unreal_: or weak spring
06:39 PM andypugh: Back in the olden days there were no front mechs and chains stayed on.
06:40 PM _unreal_: I'd lean tward big chain problems
06:40 PM jthornton: I have no need for 27 gears where I ride lol 5-6 is plenty
06:40 PM andypugh: Some of the modern 1x11 stuff has guides, but they also have some pretty extreme rear casettes and are meant for wild use.
06:40 PM _unreal_: andypugh, do you miss your penny-farthing
06:41 PM andypugh: I miss never having one. I intend to build one.
06:41 PM _unreal_: lol
06:41 PM XXCoder: yay my selfie stick just arrived
06:41 PM jthornton: actually a closer geared casette would be better
06:41 PM XXCoder: cant make to make duck faces constantly
06:41 PM _unreal_: XXCoder, my selfie stick came pre attached ((:)
06:41 PM XXCoder: not really, its for google transcript
06:42 PM XXCoder: so I can stand at distance and still have phone close enough to hear speaker
06:42 PM andypugh: I am working on my dad’s 1958 Rudge. That’s got what they would call 1x4 gearing in modern parlance.
06:43 PM _unreal_: I'm interested to see how the spindle I ordered from china works for me
06:43 PM jthornton: I've seen a bunch of photos of 50's-60's side cars on motorcycles from England some fit 4 kids lol
06:43 PM gregcnc: small tools will be fine as long as it doesn't blow up
06:43 PM jthornton: chow time here
06:43 PM _unreal_: what cha chowwing
06:44 PM andypugh: jthornton: This is a Rudge bicycle.
06:44 PM _unreal_: should have said what chaw chowing
06:44 PM _unreal_: I'm looking at boiled dinner in a bit
06:45 PM gregcnc: you really like that boiled dinner
06:45 PM _unreal_: its damn good
06:45 PM _unreal_: damn it
06:49 PM jymmmm: boiled?
06:58 PM andypugh: It’s probably not a sandwich.
06:58 PM _unreal_: heh
06:58 PM _unreal_: soggy
07:00 PM jymmmm: WTH is a "boiled dinner" ???
07:01 PM andypugh: Google suggests many possibilities
07:01 PM andypugh: But I would guess it is a dinner, that is boiled.
07:01 PM jymmmm: Is this Brit thing?
07:01 PM jymmmm: a*
07:02 PM _unreal_: jymmmm, you relaly dont know?
07:03 PM _unreal_: boiled dinner is, corn beef+ seasoning, cabbage, potato some times other items are added like carrots and many other things and spices..
07:03 PM jymmmm: Other than corned beef and cabbage, no
07:04 PM _unreal_: jymmmm, have you ever/never had boiled dinner?
07:04 PM jymmmm: corned beef, that's it
07:05 PM _unreal_: https://www.thespruceeats.com/thmb/ZbKAxbbAhTY8-O-5_yAk-QKEGMI=/3072x2304/smart/filters:no_upscale()/boiled-dinner-corned-beef-cabbage-183044382-5817a6893df78cc2e818efaf.jpg
07:05 PM _unreal_: That would be typical
07:05 PM _unreal_: jymmmm, I have a challange for you then

07:08 PM XXCoder: wrong window
07:08 PM XXCoder: sous vide
07:08 PM jymmmm: XXCoder: yeah, vacum sealed bags, then low water bath
07:09 PM _unreal_: XXCoder, good timing we are talking about food
07:09 PM XXCoder: yeah
07:09 PM _unreal_: lol
07:09 PM _unreal_: jymmmm, ya I've made that
07:09 PM XXCoder: i was talking in correct window _unreal_
07:09 PM _unreal_: when I was in the teens/20's I was a cook for a long time
07:09 PM XXCoder: the 3 word one was for google
07:09 PM jymmmm: and I've made corned beef before too
07:10 PM _unreal_: I love boiled din
07:10 PM _unreal_: gives great farts
07:10 PM XXCoder: https://www.amazon.com/Joerid-Precision-Immersion-Circulators-Adjustable/dp/B08296K1WT/ example
07:10 PM jymmmm: 14 hours on a pit, now we're talking
07:11 PM jymmmm: XXCoder: you still need the vauum sealer
07:13 PM XXCoder: didnt say anything about vacuum stuff ;)
07:14 PM _unreal_: XXCoder, lol thats asking for health problems
07:14 PM _unreal_: I could be wrong
07:14 PM _unreal_: but chances are that is an aluminum based plate with a heating coil
07:14 PM _unreal_: they go rancid in about 500 hours of use
07:15 PM _unreal_: ever taken a drip coffee maker apart?
07:15 PM _unreal_: the hotplate/water boiler are always pure aluminum. and they have so much WTF shit in them its scary
07:17 PM _unreal_: ?
07:17 PM t4nk_freenode: come on man, don't make us kick in open doors :|
07:17 PM t4nk_freenode: I thought you were discribing yourself there for a second ;)
07:17 PM t4nk_freenode: scary ;)
07:18 PM _unreal_: ahh?
07:19 PM _unreal_: interesting google use to give good results when doing any kind of a search like "crud in a drip coffee maker heating element"
07:19 PM _unreal_: now it only gives buy me now brand new results
07:21 PM _unreal_: amazing I did a search for nasty heating element in coffee maker
07:23 PM _unreal_: wow I literally can not find photos of old cruddy coffee makers
07:24 PM _unreal_: every body left :(
07:25 PM andypugh: ?
07:26 PM andypugh: “coffee element contamination” ?
07:29 PM XXCoder: i dont think I ever heard of that
07:29 PM jymmmm: What?! DONT FUCK WITH THE COFFEE m'kay
07:29 PM XXCoder: if I need coffee ill just drink stacked (weird name) of soylent

07:30 PM XXCoder: i have some green soylent too
07:30 PM XXCoder: mint choculute
07:30 PM jymmmm: XXCoder: you sick puppy
07:30 PM XXCoder: lol
07:30 PM jymmmm: IT'S PEOPLE!!!
07:30 PM XXCoder: old joke
07:31 PM XXCoder: its okay, it isnt people we know
07:31 PM jymmmm: lol
07:32 PM jymmmm: Ok, other than soylent green, is there anything that is nutritional and has an indefinite shelf life?
07:32 PM jymmmm: I could only thing of one possability.
07:33 PM _unreal_: hi sorry was doing soldering
07:34 PM _unreal_: andypugh, ya ever taken a drip coffee maker apart. any coffee maker of that kind that is more then 6 months old with heavy use the ALUMINUM heating element is beyond nasty always
07:34 PM jymmmm: run white vinegar thru it every 6 months or so
07:35 PM t4nk_freenode: or buy a new one and give the old to the homeless
07:35 PM _unreal_: acid breaks down aluminum
07:35 PM _unreal_: you then injest aluminum
07:35 PM jymmmm: cause homeless have 120Volts
07:35 PM _unreal_: aluminum causes autisum and dementia
07:35 PM t4nk_freenode: they are just interested in selling it for crack ;)
07:36 PM jymmmm: ah
07:36 PM _unreal_: jymmmm, even light acids will eat aluminum
07:36 PM jymmmm: deoderant = aluminum oxide
07:36 PM t4nk_freenode: yeh, citrus is renowned for eating right through your kitchen deck
07:37 PM jymmmm: that's why every 6 months, not every week
07:38 PM _unreal_: its a proven fact elderly with dementia have high aluminum levels in there body mainly in the brain
07:38 PM jymmmm: Other than my half sheet pans, I only have one aluminum griddle for cooking gear
07:38 PM _unreal_: you can look it up
07:38 PM XXCoder: austism is genetic.
07:38 PM XXCoder: not alum or chemical anything
07:39 PM XXCoder: you probably belive vaccines cause austism also
07:39 PM t4nk_freenode: rather bold a statement
07:39 PM t4nk_freenode: are you a doctor?
07:39 PM XXCoder: i follow actual science articles not bullshit sites
07:39 PM jymmmm: There is suppose to be a link between aluminum light metal poisoning and memory
07:39 PM andypugh: I have heard of the aluminium link to alzheimers before.
07:40 PM XXCoder: i dont know about alzheimers
07:40 PM jymmmm: memmmmory loss that is
07:40 PM andypugh: But it’s hard to believe that anyone could get enough alumnium in time to become autistic at the age than appears.
07:40 PM jymmmm: andypugh: deoderant
07:41 PM andypugh: Deodorant is aluminium oxide. That’s 1) not going to be absoved through the skin and b) will stay as the oxide if it did.
07:41 PM jymmmm: andypugh: Not sure if it's "build up" of aluminum in the system, or perhapse that alumimum "stuns" memory capacity with enoug long term exposture
07:42 PM XXCoder: "deodorant autistic kids" no result at all. not even crackpot sites
07:42 PM andypugh: In any case, if it is long-term that can’t cause autism at the age that is normally diagnosed.
07:42 PM andypugh: And do folk actually deodorise babies?
07:42 PM jymmmm: google "deoderant memory"
07:43 PM XXCoder: andy yep! my nephew was diahnosed at year old or 2? not sure exactly age but young
07:43 PM jymmmm: most commerical kitchens use LARGE aluminum pots
07:43 PM XXCoder: you use antacids?
07:44 PM andypugh: XXCoder: And had he been heavily deodorised for those 2 years?
07:44 PM XXCoder: andy lol nope
07:44 PM XXCoder: they didnt have much alum then
07:44 PM _unreal_: andypugh, autistic is a genetic disorder caused by failed genetic code from one or both parents. there are also reports of high levels of dimentia from grand parents of parents with autistic children
07:44 PM _unreal_: That is a fact as well
07:45 PM _unreal_: @#$%!@#$ google is pissing me off
07:45 PM andypugh: And that points at aluminium how?
07:45 PM _unreal_: buy me buy me
07:45 PM * infornography buys
07:45 PM _unreal_: infornography, you bitch
07:45 PM _unreal_: sell sell
07:45 PM _unreal_: heh
07:46 PM infornography: consume, obey
07:46 PM jymmmm: Interesting deoderant linked to shaving and breast cancer
07:46 PM _unreal_: andypugh, that means its likely the grand parents had a lifestyle that put them in contact with aluminum a lot. aluminum cookware. for starters. makeup
07:46 PM _unreal_: and many other things
07:47 PM _unreal_: jymmmm, all developed countries have the highest levels of health issues
07:47 PM jymmmm: https://www.alzdiscovery.org/cognitive-vitality/blog/is-there-a-link-between-aluminum-and-alzheimers
07:47 PM infornography: deoderant linked to shaving?
07:47 PM andypugh: yes, and they somehow transferred this lifetime accumulation of aluminium to their great granchchildren?
07:47 PM jymmmm: So not absired thru pores, but can thru kicks and cuts
07:47 PM skunkworks: andypugh: https://youtu.be/P0RP7s-rDsg
07:47 PM andypugh: That seems mean of them.
07:47 PM _unreal_: infornography, deoderant linked to +1 with lady luck
07:48 PM andypugh: skunkworks: Already watched. You are right about the encoder.
07:48 PM jymmmm: but one other study reported that patients who used antiperspirant products more frequently and longer on shaved underarms were diagnosed with breast cancer at an earlier age [21]. Studies show that aluminum salts in antiperspirants are poorly absorbed by the body, and the little that is absorbed is flushed out by the kidneys [22][23]. However, if you regularly shave with a razor, aluminum may be more readily absorbed via small ni
07:48 PM jymmmm: cks and abrasions.
07:49 PM infornography: People who don't shave dont use deodorant ... my sides X)
07:50 PM _unreal_: jymmmm, your 1000x more likely to EAT aluminum then absorb
07:50 PM skunkworks: andypugh: I played with your pid solution - but didn't get very far
07:51 PM _unreal_: jymmmm, if you use tinfoil and any kind of citric acid. limes lemon etc....... and other foods they will dissolve tin foil. once dissolved you end up eating it.
07:51 PM _unreal_: https://th.gorenje.com/en/life-simplified/food-simplified/good-advice/plastic-aluminium-foil-or-container-how-to-keep-your-food-fresh
07:52 PM _unreal_: LOL https://www.hunker.com/13415050/how-to-dissolve-aluminum-foil-with-vinegar
07:56 PM _unreal_: back in a few. just had a power blip and my UPS that I have yet to put the new battery into just shut off
07:56 PM * _unreal_ loves his laptop
07:58 PM skunkworks: andypugh: I mean - it was all hooked up but was a bit hard to tune.
07:58 PM andypugh: Should be all FF0 and a hint of I, I think.
08:16 PM _unreal_: sup
08:18 PM _unreal_: LOL came accross a great report more FAKE news
08:19 PM _unreal_: so all of the NEWs broadcasts are being "" done "" from home.. well News Publishers Deemed “Essential” they can GO to work no issues.
08:19 PM _unreal_: lol
08:22 PM JavaBean: where you at? in us?
08:25 PM Tom_L: skunkworks, are you still using the rpi4 on the green machine?
08:27 PM skunkworks: Tom_L: yes
08:27 PM Tom_L: come across any issues with it?
08:28 PM skunkworks: it has been pretty stable - I was getting noise in the form of pressed keys (I think because of a really crappy keyboard) but switching to a wireless keyboard the problem went away
08:29 PM skunkworks: I should say - it has been stable. (pretty stable sounds crappy ;)
08:29 PM skunkworks: on a machine control anyway
08:29 PM Tom_L: with a 7i92?
08:30 PM skunkworks: yes - Ethernet. (although I have to run a 500hz servo thread.)
08:30 PM Tom_L: no issues with that though?
08:30 PM skunkworks: I think peter says the spi interface can be run faster.
08:31 PM skunkworks: no
08:31 PM _unreal_: JavaBean, are you talking to me?
08:31 PM Tom_L: is the spi a working interface though?
08:31 PM skunkworks: since the whole timesyncd thing - no
08:31 PM JavaBean: yeah, just wondering where you are that the media can't bother to work
08:31 PM skunkworks: Tom_L: That would be a question for peter or maybe jthornton
08:31 PM _unreal_: florida
08:31 PM skunkworks: I don't know how far along it is
08:32 PM _unreal_: JavaBean, I'm still working
08:32 PM Tom_L: i thought jepler was messin with the spi at one point
08:32 PM skunkworks: I thought it was good though
08:32 PM JavaBean: ha, another one of you floridaman
08:32 PM Tom_L: but that was a while back
08:32 PM _unreal_: in florida its really only resturants and stuff liek that that got fucked
08:32 PM _unreal_: news are considered essential
08:32 PM _unreal_: and they are braudcasting from home

08:33 PM _unreal_: broadcasting
08:33 PM _unreal_: the news is SOOOOOOO fake its scarry
08:33 PM _unreal_: JavaBean, I believe a lot of this COVID bs is really to kill the stock market so that other countries can buy up huge market share
08:34 PM _unreal_: china just purchased 30% of some cruise ship stocks
08:34 PM JavaBean: not one i have heard before
08:34 PM _unreal_: regardless the wise are investing like crazy
08:35 PM _unreal_: I've purchased for example 10 shares of RCL and 10 shares of NCLH
08:36 PM _unreal_: one averages 130 $$ the other $60
08:36 PM _unreal_: a share
08:37 PM _unreal_: JavaBean, I did this mainly because that should net me about $1500 and they are high dividend feeders
08:37 PM _unreal_: SOOOO
08:38 PM _unreal_: next I'll start looking for the next amazon nvidia etc...
08:38 PM _unreal_: JavaBean, do you do stocks at all?
08:39 PM JavaBean: no, i have none... but considering how much money i have, its what i can afford

08:39 PM _unreal_: google this
08:40 PM _unreal_: google " amzn stock "
