08:11 AM elmo40: moo
08:12 AM XXCoder1: n
11:16 AM fragalot: I should start one of those "restoration" youtube channels... Just chuck something outside with some salt sprinkled on it, clean it up, and rake in the views
11:18 AM gregcnc: did you watch the abom video?
11:18 AM fragalot: yeah, but there's just a butt-load of channels that don't do anything else
11:19 AM fragalot: and the concept seems so simple
11:19 AM fragalot: place item in outdoor scrapbin & wait
11:19 AM gregcnc: i didn't watch it. The draw must be if it's going to look decent after
11:19 AM fragalot: get said item back out, evaporust it
11:19 AM fragalot: take said item and wire-wheel or bead-blast it
11:20 AM fragalot: take said item, polish it
11:20 AM fragalot: paint
11:20 AM fragalot: done
11:20 AM fragalot: the key is to polish, even if it really really does not call for it
11:20 AM gregcnc: be rich soon, you got this
11:20 AM gregcnc: magnet fishing is another fun one
11:21 AM fragalot: i'm afraid of what i'd find, lol
11:21 AM gloops: better off learning decoupage
11:21 AM gloops: cover everything in chintz paper serviettes, rub the corners off with sandpaper $$$
11:21 AM gregcnc: does nobody make small pumps like Little Giant?
11:22 AM gloops: also better birds involved than many other crafts
11:22 AM fragalot: gregcnc: could you be more specific?
11:22 AM gregcnc: http://littlegiant.com/products/industrial/small-submersible-pumps/nk-2-series/
11:23 AM gregcnc: I'm just being cheap trying to scrounge one of ebay or I'd buy one new, but it seems they are the only game in town
11:24 AM fragalot: i'm trying to remember one of the brands we make >.>
11:25 AM gregcnc: I did find one ebay cheap, but just got an email saying they can't ship because they made a mistake in the listing...
11:26 AM fragalot: does it have to be submersible?
11:27 AM gregcnc: at this size it would be easiest to drop it in the tank
11:28 AM fragalot: I got nothing. :)
11:34 AM fragalot: you could get a crappy shurflo submersible -- or does it have to be reliable long-term? :P
02:06 PM MacGalempsy: hello
02:09 PM JT-Shop: hay
02:09 PM Deejay: straw
02:11 PM MacGalempsy: bales of hay
02:12 PM MacGalempsy: JT have you tried an SLA printer yet?
02:14 PM JT-Shop: no
02:15 PM MacGalempsy: What are you making these days? Nothing made around here in a bit.
02:22 PM MacGalempsy: hello Andy
02:23 PM andypugh: Hi
02:23 PM MacGalempsy: Are you still using Fusion360?
02:23 PM andypugh: Sometimes
02:24 PM MacGalempsy: Did you have to start paying for it, or were you able to keep using it for free?
02:24 PM andypugh: I had to re-license, but for free, again.
02:25 PM MacGalempsy: ah, good deal. it has been a few years since using it, but about to get back in the design mode...
02:27 PM andypugh: Many alternative suggersions here: https://hackaday.com/2019/01/11/ask-hackaday-help-me-pick-a-cad-package/
02:32 PM gregcnc: I saw solidworks has a free license for startups, but there are some hoops
02:34 PM MacGalempsy: hoops were meant to be jumped thru :)
02:34 PM gregcnc: like you need a real company
02:35 PM MacGalempsy: does and EIN qualify one as a real company?
02:36 PM gregcnc: check their site. my reaseller called and left a message, so I was looking at the SW site to see if there was something I couldn't live without
02:36 PM MacGalempsy: it would be nice to just get re-upped on f360
02:37 PM gregcnc: i did. f360 must check on actual usage. i think i'm on my 3rd free test drive
02:37 PM gregcnc: I don't use it
02:37 PM MacGalempsy: still kicking around a SLA printer and F360 is so easy to get a STL from
02:38 PM MacGalempsy: that Peopoly Moai is pretty slick. the website shows they are working on a 1ft^3 model
02:39 PM MacGalempsy: it only cost $100 in resin to print a yoda head lol
03:02 PM MacGalempsy: zzz
03:04 PM fragalot: I almost bought a moai
03:05 PM MacGalempsy: what stopped you?
03:05 PM fragalot: miss0r made me buy a schaublin mill instead
03:05 PM fragalot: and ye olde funds only stretch so far
03:05 PM MacGalempsy: last week there were two on ebay, one went for under $1k and the other was $1250
03:06 PM MacGalempsy: so they were claiming open source, but they would not release the firmware which controls the galvos
03:07 PM MacGalempsy: https://peopoly.net/pages/project-dfa this is the one I am holding on for
03:07 PM MacGalempsy: it will probably hit kickstarter first, like the Moai
03:08 PM fragalot: interesting
03:09 PM MacGalempsy: it almost looks like it has a galvo and an LCD screen
03:09 PM MacGalempsy: the build place is 300mm x 300mm x 300mm
03:09 PM fragalot: and top-down
03:10 PM fragalot: am I mistaken, or does that actually mean that you'll need a LOT more resin in the tank?
03:11 PM MacGalempsy: probably will need more resin, depending on the print
03:11 PM MacGalempsy: the Phrozen one on Kickstarter has 2 difference LCD screens, a large 13.1 and dual 5.5
03:13 PM MacGalempsy: the most amazing part is the layer resolution, but printing at 25um would take forever
03:13 PM fragalot: :P
03:27 PM XXCoder1: fragalot: some does seem to find actual rusty stuff, and some channel looks like they come from salt water buckets. rust was so even
03:28 PM MacGalempsy: https://www.youtube.com/watch?v=tti4-9ADYLs
03:28 PM MacGalempsy: opensource structure light scanner results. wow
03:28 PM fragalot: XXCoder1: Exactly
03:28 PM fragalot: XXCoder1: and I know where I could get both :P
03:29 PM MacGalempsy: https://github.com/jakobwilm/slstudio
03:29 PM XXCoder1: lol
03:49 PM milkii_ is now known as milkii
03:51 PM Jymmm: How to Notch Tubes Without a Tube Notcher https://www.youtube.com/watch?v=mHBanmfn_CA
04:00 PM MacGalempsy: anyone try this one yet? https://github.com/theICTlab/3DUNDERWORLD-SLS-GPU_CPU
04:03 PM Deejay: gn8
04:09 PM andypugh: Jymmm: I can make my mill into a tube notcher with just a hole saw. But I don’t have a cut-off saw like he uses.
04:27 PM Jymmm: andypugh: I just thought the technique he showed (the 1/3rd thing) was pretty cool, even with the 10degree bend.
04:28 PM andypugh: I like that he gets an automatic weld bevel
04:29 PM Jymmm: =) Just thought it be something folks in here could learn/appreciate =)
05:07 PM jthornton: I wonder if checking my data usage uses up some of my data
05:08 PM phipli: sometimes if it is on the isp's site it doesn't count
05:09 PM jthornton: hey phipli hows it going
05:09 PM phipli: badly
05:09 PM phipli: trashed the install on my always on SBC
05:09 PM phipli: broken ssh and the vpn
05:09 PM phipli: all because I ran apt update
05:10 PM phipli: (am in good health etc :) )
05:10 PM phipli: yourself?
05:10 PM jthornton: I hate when that happens
05:10 PM phipli: I really don't want to lose this install
05:10 PM jthornton: we are doing good, the one that moulted is my star performer now lol
05:10 PM phipli: it has too many hours of setup
05:10 PM phipli: loose*
05:11 PM jthornton: I tried to install my server and motioneye but for some reason it does not work... I guess I try again
05:14 PM phipli: I fixed one "failed" item from boot
05:14 PM phipli: didn't fix the rest
05:20 PM jthornton: I've built a new auto door with a 7" touch screen for the shed conversion
05:29 PM phipli: :)
05:30 PM phipli: I set up an official raspberry pi 7" screen for my brother
05:30 PM phipli: How will it be with humidity?
05:31 PM jthornton: I hope ok, it will be outside the actual coop area
05:34 PM phipli: Things are getting worse here - I've now broken wifi... but I have a backup - stupidly from 5 minutes after the update
05:34 PM phipli: such an idiot
05:34 PM phipli: internet working again at least
05:35 PM jthornton: sounds like your having fun now
05:35 PM phipli: :(
05:35 PM phipli: should be in bed
05:35 PM Tom_L: maybe you should. it would probably look better rested
05:35 PM phipli: :)
05:36 PM jthornton: yea tired eyes and mind equal mistokes
05:36 PM phipli: Tom_L, there is an upstream linux bug in systemd that is trashing arm linux installs
05:36 PM jdh: impossible. systemd is the solution to everything.
05:36 PM phipli: it has broken what is basically my vpn / cron box
05:36 PM Tom_L: feature
05:37 PM phipli: :)
05:37 PM phipli: yes, I have already started the gofundme to hunt down the creator of systemd
05:37 PM * phipli reboots and hopes
05:38 PM phipli: now that I know it is systemd (only took several hours)
05:38 PM phipli: I've rolled it back
05:38 PM * phipli dances
05:38 PM * phipli cries with glee
05:38 PM * phipli has a vpn again
05:39 PM phipli: all this started because I wanted to move the OS to a bigger SD card
05:39 PM phipli: and decided to update it before I backed it up due to stupidity
05:40 PM * phipli backs up the SD card quickly
09:36 PM tiwake: anyone know of a chemical that I can pour into an aluminum engine block to dissolve a stuck bolt?
09:38 PM tiwake: but not hurt the block
09:39 PM Tom_L: https://mechanics.stackexchange.com/questions/39091/best-way-to-remove-rusted-steel-bolts-from-aluminum-parts
09:39 PM Tom_L: some suggestions
09:42 PM tiwake: Tom_L: the thing is the bolt I need to remove is really deep in the block
09:43 PM tiwake: can't weld a nut on it or use a torch
09:44 PM tiwake: the threads start like 3" deep into the block
09:55 PM ziper: tiwake, i don't think chemically is the way to go
09:55 PM ziper: what bolt is it
09:58 PM tiwake: head bolt
09:58 PM tiwake: but the threads for the head bolt are super recessed
10:02 PM ziper: how many bolts are there total
10:03 PM tiwake: just one thats busted
10:05 PM ziper: 14/15 is fine
10:10 PM tiwake: I think I'm just going to try soaking in croil for a long time and drilling it out
10:22 PM MarcelineVQ: you could drill out the body and use alum (the chemical) in it to try to dissolve the leftover thread, I've only seen mixed results from the method though
10:24 PM MarcelineVQ: an ave vid on the topic https://www.youtube.com/watch?v=7pN-fnUeA3o seems to require heating though
10:25 PM MarcelineVQ: aluim is 3 mins in
