12:02 AM ziper: i 3d printed a jig but i doubt it will work
01:59 AM Deejay: moin
05:10 AM jthornton: morning
05:10 AM XXCoder: morning
05:13 AM XXCoder: jthornton: I got black 3.0 paint lol
05:13 AM XXCoder: damn its very dark
05:14 AM jthornton: what is it used for
05:14 AM XXCoder: curious mostly lol
05:14 AM XXCoder: im also considering solar oven
05:14 AM XXCoder: but maybe not, it may be too effecient and burn paint itself
05:16 AM Tom_L: morning
05:16 AM XXCoder: yo
05:17 AM jthornton: building the rt preempt kernel on the rpi4
05:17 AM Tom_L: fun
05:18 AM jthornton: openbox is interesting as it's almost a blank slate
05:19 AM XXCoder: I think its pretty amazing that rp4 can run cnc
05:19 AM XXCoder: moreover, its very repeatable system
05:19 AM XXCoder: buy same board and same mesa or whatever, and it should perform the same, on fresh install
05:20 AM jthornton: yea the rpi4 should work fine with any of the mesa ethernet boards and there are a couple of spi boards as well
05:21 AM XXCoder: pretty cool allright
05:46 AM XXCoder: oh yeah jt I previously painted a sample of black 2.0 on cardboard, then painted 3.0 by it
05:47 AM XXCoder: black 2.0 was darkest mattest black before 3.0, but 3.0 makes it look gray
06:11 AM Inline__ is now known as Inline
06:27 AM jthornton: does the background color make any difference?
06:28 AM XXCoder: it was white cardboard
06:29 AM XXCoder: virtu8ally worse possible, since it grabs paint and lightens it
07:16 AM Deejay: re
07:38 AM Loetmichel: *ha* finally a useful 3d-print... (had to redo it though because wife didnt like the blue...) now to print 7 more... the wooden ones lasted only 5 years. Note to self: plywood and rain: bad idea ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17475&g2_imageViewsIndex=1
07:45 AM Loetmichel: one clamp runs 4.5 hours on the printer though... will take a few days more to change them all from disintegrating plywood to PLA ;)
08:53 AM gregcnc: this is amusing https://www.practicalmachinist.com/tips-and-tricks/10-essential-machinist-tools/
08:56 AM XXCoder: hm im missing machinist handbook lol
10:06 AM perry_j1987: when does one need a scale?
10:06 AM perry_j1987: i havnt found the urge to use one so havnt bought one yet
10:19 AM * roycroft has at least a dozen different scales, and would feel naked in the shop without a 6" scale in his pocket
10:21 AM perry_j1987: what do you use it for that a caliper doesnt work
10:37 AM Tom_L: perry_j1987 for cutting rough stock
10:37 AM Tom_L: save the precision tools for precision
10:38 AM perry_j1987: i'd grab my crappy pair and use to scribe line at set length etc
10:38 AM Tom_L: i've got 6, 18 & 24" scales
10:39 AM Tom_L: oh and a couple 12"
10:39 AM Tom_L: use the 6" mostly for spreading peanut butter
10:39 AM Tom_L: :D
10:41 AM roycroft: i have scales going up to 48" in american customary units, and up to 1000mm in metric
10:42 AM roycroft: a scale is a *lot* faster to grab a quick measurement than a caliper
10:42 AM roycroft: and there are heaps of uses that don't work out well with a caliper
10:44 AM roycroft: just as one example, if i'm making a bunch of parts that are 8" long, i'll put a 12" blade in a combination square, set it to a fraction over 8", and use that to set the stock in my bandsaw
11:32 AM perry_j1987: interesting
12:10 PM jdh: put the 8" stop on your band saw
12:38 PM roycroft: mine did not come with one, and while i do have an improvised one, it's just as fast to use the combination square
12:39 PM roycroft: besides, i'd need a scale to set the stop in the first place :)
12:40 PM _unreal_: ok milling my grape vine into the cheese cutting board
01:32 PM _unreal_: and there is the daily lighting storm
01:34 PM zhivko: Hi guys!
01:34 PM zhivko: I have problem when I issue g38.3 I am getting error: "No characters found in reading real value"
01:35 PM zhivko: What could be the problem? What this error means - I googled it and cannot find any explanation
01:36 PM zhivko: anybody here ?
01:36 PM Jymmm: little slow today
01:37 PM zhivko: Jymmm
01:37 PM zhivko: my man
01:37 PM zhivko: Do you use G38.2 ?
01:37 PM zhivko: or any G38
01:38 PM zhivko: I have problem when I issue g38.3 I am getting error: "No characters found in reading real value"
01:43 PM zhivko: any other here ?
01:44 PM jdh: did you specify 1 or more axes?
01:48 PM zhivko: only 1
01:48 PM zhivko: Z
01:49 PM zhivko: g38.3 Z
01:49 PM zhivko: is giving this error
01:51 PM zhivko: What can I check ?
01:51 PM zhivko: what real value is beeing read ?
02:01 PM zhivko: Ah
02:01 PM zhivko: It works with
02:01 PM zhivko: G38.3 Z10 F50
02:01 PM zhivko: thanks guys
02:07 PM JT-Shop: seems to be plainly spelled out in the manual...
02:52 PM _unreal_: just an UPDATE so I tried doing a milling job with these DIAMMOND coated drill bit I have. and they work great!!!!!!!!!!!!!!! BUT you have to use a very slow feed rate. they like to bend
03:02 PM _unreal_: So what do you guys think? https://drive.google.com/open?id=1Jhdu2UXy-NDLAabpD3d6cB-wlT9qazFm
03:05 PM gloops: looks ok to me
03:05 PM _unreal_: only ok :)
03:10 PM gloops: well by ok i mean i cant see anything wrong with it - its a pass
03:11 PM gloops: mine is no better https://ibb.co/ncnQsHd
03:11 PM _unreal_: church view?
03:11 PM _unreal_: wat does it stand for?
03:12 PM _unreal_: funny thing... I grew up on the road Church ST. in ellsworth maine as a kd
03:12 PM _unreal_: kid
03:12 PM CaptHindsight: looks like it's made of wood
03:12 PM gloops: church view - thats the name of the house
03:13 PM _unreal_: CaptHindsight, that is clearly pulp laminated ceramic
03:13 PM gloops: not my house
03:13 PM CaptHindsight: yep, wood
03:14 PM _unreal_: !!!!!! here are no screw heads in the screw holes HOW the hell is it staying in place
03:15 PM CaptHindsight: the sign was placed on a wooden deck
03:16 PM CaptHindsight: the sign is held by pegs not shown in its rear
03:16 PM CaptHindsight: sign is bonded to wall with adhesives or tape
03:17 PM gloops: in the box thinking
03:17 PM gloops: there is no sign
03:17 PM CaptHindsight: sign was screwed to door through the back of the sign
03:18 PM CaptHindsight: sign and wall carved from same block of wood
03:18 PM CaptHindsight: sign was thrown at door and photo snapped with high speed camera
03:19 PM CaptHindsight: entire photo was rendered
03:19 PM gloops: https://ibb.co/vzthgGM
03:19 PM gloops: pixwl by pixel with an eyedropper tool
03:19 PM CaptHindsight: nobody is really here, this is just a dream
03:20 PM CaptHindsight: sign was screwed to door then screw heads removed by laser
03:21 PM CaptHindsight: wooden screws used to hold sign, termites used to remove screw heads for photo
03:22 PM CaptHindsight: transparent screws used to hold sign
03:25 PM _unreal_: taking my daughter to the movies
03:25 PM _unreal_: later
03:25 PM gloops: i pushed a boarded screen onto the water, dived in with waterproof camera and sign, then let the sign float up to the screen
03:25 PM _unreal_: going to see angry birds
03:25 PM _unreal_: 2
03:25 PM CaptHindsight: screw heads printed to look like holes in sign
03:25 PM CaptHindsight: sign is actually holding up wall
03:25 PM gloops: someone in ebay just takes a photo of a board with a black text layer in front lol
03:25 PM CaptHindsight: no lets keep going
03:27 PM CaptHindsight: hazzy-m: https://qtpyvcp.kcjengr.com/install/index.html is this ready to go or still a work in progress?
03:29 PM CaptHindsight: hazzy-m: will this be transportable to the Rpi 4? https://qtpyvcp.kcjengr.com/install/quick_start.html
04:33 PM Deejay: gn8
04:42 PM infornography: Every machine is a smoke machine if you operate it wrong enough.
04:55 PM roycroft: and it's a smokin' machine if you operate it well enoug
04:59 PM CaptHindsight: way back when i lost some points off my grade when i pushed the brake lathe in HS to its limits
05:43 PM nubcake is now known as nubcake_
05:43 PM nubcake_ is now known as nubcake
05:45 PM nubcake is now known as nubcake_
05:45 PM nubcake_ is now known as nubcake
07:14 PM _unreal_: and no one is around on any channel
07:14 PM _unreal_: and I'm stuck being daddy at home :)
07:14 PM _unreal_: oh well
07:14 PM XXCoder: aww
07:14 PM XXCoder: btw im not here, im telepathically typing
07:15 PM _unreal_: I figured as much
07:36 PM Tom_L: i'm not either
07:36 PM XXCoder: wow fellow telepath hi
07:45 PM roycroft: i'm never here
07:45 PM roycroft: even when i am
07:45 PM XXCoder: roy im not here because im behind you
07:45 PM roycroft: and that's a tricky place to be because you don't know where i am
07:46 PM XXCoder: sure people do need conforting illusions. going off elsewhere
07:46 PM * roycroft is trying to decide what he thinks of this cider
07:46 PM XXCoder: you made it?
07:47 PM roycroft: i met a cider maker when i was down in humboldt county and she was telling me about her ciders
07:47 PM roycroft: i picked one up at the north coast food coop
07:47 PM roycroft: it's pretty good, but she said she oaked it fairly heavily
07:47 PM roycroft: and i'm just not getting much of that
07:48 PM roycroft: there should be some fairly strong vanilla/marshmallow/coconut notes to the cider, and there'a pretty much none of that
07:48 PM roycroft: on the other hand, it's nice and dry
07:48 PM XXCoder: oaked?
07:48 PM roycroft: aged in oak barrels
07:48 PM XXCoder: ahh
07:48 PM roycroft: i can't stand most commercial ciders - they're way too sweet
07:48 PM roycroft: most of them are not even cider
07:49 PM roycroft: they're grain alcohol, sugar, water, co2, and apple flavor all mixed together and passed off as something drinkable
07:50 PM XXCoder: fun
07:51 PM XXCoder: i dont drink alchol anything
07:55 PM roycroft: i don't drink much these days, but as someone who has been brewing for almost 40 years, i'm not really interested in totally abstaining
07:56 PM roycroft: i do focus on quality, for sure
07:56 PM roycroft: i got some blackberry mead that is made in chico when i was down there too
07:56 PM roycroft: funny that i spotted it, as i've never seen blackberry mead sold commercially before, and i'm about to make a batch myself
07:56 PM roycroft: in fact, i'm heading out in a couple minutes to pick more blackberries
07:57 PM roycroft: i've picked 5kg so far, and i need 10kg for the batch, so i'm halfway there
07:57 PM XXCoder: :)
07:57 PM CaptHindsight: are meads defined by not being made from wheat and not distilled?
07:57 PM _unreal_: I've made a lot of different meads
07:57 PM roycroft: no
07:57 PM XXCoder: im not anti alchol, i just dont need any ponental issues since I have way too many'
07:57 PM roycroft: mead is fermented honey
07:58 PM roycroft: beer is fermented grain (primarily barley)
07:58 PM _unreal_: roycroft, my best home brew for mead ever was raspberry mead
07:58 PM CaptHindsight: honey alone or + other fruit
07:58 PM roycroft: wine is fermentee dgrapes
07:58 PM roycroft: grapes
07:58 PM roycroft: cider is fermented apples
07:58 PM roycroft: honey + fruit is technically called a melamel
07:58 PM CaptHindsight: ah as long as it starts with honey
07:59 PM roycroft: but it's definiately a "mead"
07:59 PM roycroft: beer can have honey in it as well as grain
07:59 PM roycroft: but when the amount of honey becomes significant (>35% or so) it's called a braggot
08:00 PM CaptHindsight: have to get the handbook
08:00 PM roycroft: honey + apples is cyser
08:01 PM roycroft: honey + spices is metheglin
08:01 PM roycroft: honey + grapes is pyment
08:01 PM CaptHindsight: honey + Clostridium botulinum = poison
08:02 PM roycroft: pathogenic organisms cannot live in fermented beverages
08:02 PM roycroft: the alcohol content and low pH form a hostile environment for them
08:02 PM CaptHindsight: roycroft: i know you practice goo hygene both personally as well as with your brewing apparatus but have to ever had a problem with bacteria in your brews?
08:03 PM roycroft: not unintentional bacteria
08:03 PM CaptHindsight: goo/good
08:04 PM roycroft: i've made several beverages where i intentionally add or cultivate lactobacculus to sour the beer
08:04 PM CaptHindsight: sure
08:04 PM CaptHindsight: was only thinin about the bad guys
08:04 PM roycroft: as i said above, pathogenic bacteria cannot live in beer
08:04 PM roycroft: it's not a problem at all
08:04 PM roycroft: not for anyone
08:05 PM roycroft: the worst thing that can happen is you get some bacteria that makes the beer taste like arse
08:05 PM roycroft: you might throw up from the revolting taste
08:05 PM roycroft: but you won't get sick
08:05 PM CaptHindsight: yes, very common
08:06 PM roycroft: that's why beer is so common in places where the water is not suitable to drink
08:06 PM CaptHindsight: or just the intended ingredidents
08:06 PM roycroft: you can take that nasty water and make beer with it
08:06 PM roycroft: and it will be drinkable
08:06 PM roycroft: maybe not really tasty
08:06 PM roycroft: but at least drinkable
08:07 PM CaptHindsight: https://jfoodprotection.org/doi/pdf/10.4315/0362-028X.JFP-10-546
08:07 PM CaptHindsight: The pathogens E. coli O157:H7 and Salmonella Typhimurium could not grow in the mid-strength or full-strength beers, although
08:07 PM CaptHindsight: they could survive for more than 30 days in the mid-strength beer when held at 4uC. These pathogens grew rapidly in the alcohol-
08:07 PM CaptHindsight: free beer; however, growth was prevented when the pH of the alcohol-free beer was lowered from the ‘‘as received’’ value of 4.3 to 4.0. Pathogen survival in all beers was prolonged at lowered storage temperatures.
08:12 PM roycroft: that confirms what i said
08:16 PM roycroft: my gilsonite should arrive by next weekend
08:16 PM roycroft: i'm looking forward to doing some japanning to see how it turns out
08:34 PM roycroft: btw, hops also inhibit bacterial growth
08:35 PM roycroft: this is how the ipa style evolved in the uk - casks of beer shipped to india had to survive for months in tropical heat en route to their destination
08:35 PM roycroft: so brewers started brewing stronger beer, and hopping it heavily, to help preserve it for the long, arduous journey
08:55 PM CaptHindsight: what hops and yeasts are used to make beer taste like burned rice with hints of metal can?
08:56 PM XXCoder: powder made from metal can and and burnt rice
08:58 PM roycroft: do
08:58 PM roycroft: i've never eaten burned rice with notes of metal can
08:58 PM roycroft: so i can't tell you how i would make beer that tastes like that
08:59 PM roycroft: a high carbonation level can give a beer a metallic flavor
08:59 PM Tom_L: or why you would
09:00 PM CaptHindsight: new logo https://pabstblueribbon.com/
09:00 PM roycroft: as brussels sprouts are the new kale, burnt rice with iron might be the new brussels sprouts
09:00 PM roycroft: one never knows
09:03 PM CaptHindsight: https://www.youtube.com/watch?v=qOYLRnuQIQM
09:22 PM MarcelineVQ: they are? that's good news, brussel sprouts actually taste good unlike kale
09:27 PM roycroft: yeah, that sucks
09:27 PM roycroft: when kale became a big fad i did not mind
09:28 PM roycroft: while i don't dislike kale, i also am not a big fan of it
09:28 PM roycroft: but i have always loved brussels sprouts
09:28 PM XXCoder: kale goes well with ANY soup
09:28 PM roycroft: and i hate fads
09:28 PM XXCoder: sadly havent had soup for while, nor any kale.
09:28 PM roycroft: so i was unhappy when brussels sprouts became a fad
09:28 PM XXCoder: kale is also pretty goddamn tough
09:29 PM roycroft: i love to make collard greens southern style
09:29 PM CaptHindsight: kale beer
09:29 PM roycroft: they are pretty tough too
10:57 PM justanotheruser is now known as justanotherchad
