12:01 AM XXCoder: later
12:44 AM Elmo40: any way to use that software to wrap 3D printing over 4th axis?
12:57 AM miss0r2: mornin'
12:59 AM Elmo40: anyone see this nice vid from last month?
12:59 AM Elmo40: https://www.youtube.com/watch?v=1dy8Dgzcgq4
01:57 AM Deejay: moin
03:43 AM miss0r2: I have two Racom MR400 links with antennas & cables for them. Anyone interrested? if not they are heading for the trash
04:46 AM jthornton: morning
04:49 AM XXCoder: hey
04:49 AM XXCoder: modens interesting
04:53 AM miss0r2: They are in the trailer now - you can still have'em :)
04:53 AM XXCoder: nah dont need em
04:53 AM miss0r2: jthornton: I don't suppose I can instrest you in a set of 10km range serial to radio modems? :D
04:54 AM jthornton: not sure what I'd do with that
04:54 AM miss0r2: remote control the henhouse
04:55 AM jthornton: but it's only 10' from my house lol
04:55 AM miss0r2: so, turn down the signal strength a little :D
04:55 AM jthornton: lol
04:56 AM miss0r2: meh - This is just the 3rd time I've moved it around during a shop cleaning. Now they have to go
04:56 AM jthornton: what did you use them for?
04:57 AM miss0r2: I didn't. I took them down a few years back. They were used as a link between a main station and a substation in a city wide sewage system. It was replaced with an ADSL line, once phone lines reached that area
04:58 AM miss0r2: anyway - I have to get running. I have a client waiting. see you around
04:58 AM jthornton: ok
05:14 AM Tom_L: morning
05:22 AM jthornton: morning
05:22 AM XXCoder: morning
06:12 AM _unreal_: miss0r2, What is there range?
06:13 AM _unreal_: if they could do 800' would have KILLED FOR those 28 years ago. back in the 90's when my best friend and I were doing DIAL up doom2
06:13 AM _unreal_: OMG...
06:30 AM miss0r2: _unreal_: I seem to recall the range is 10km
06:34 AM miss0r2: _unreal_ and you can still take up playing doom or diablo1 or any other serial based game.
06:34 AM miss0r2: It also has an ethernet port... I can't remember the exact speed it supports. probably slow
08:26 AM Elmo40: can you believe there are places that still don't have ADSL available to them?
08:41 AM jthornton: I can, the only thing we have out here is electricity...
08:42 AM Elmo40: one of the largest distributors of fibre in optics in Ontario was HydroOne (electrical company)
08:42 AM Elmo40: it stretches 2/3 the length of the Province!
08:44 AM Elmo40: problem is it was not meant for your door step... only main nodes were created. it was up to the local telecom to get it to your door. not enough ROI for a guy who is ~50km from the nearest node, in the swamp laiden bush we have in the North.
08:44 AM jthornton: we have fiber 1.5 miles away... obama fiber so nothing is using it lol
08:44 AM Elmo40: LoL
08:45 AM jthornton: looks like I finally got the Ender 3 tweaked in, getting a very good print
08:51 AM roycroft: the last mile is where the cost is
08:53 AM roycroft: and btw, i put in 48 strands of "obama fiber" 10 years ago, and we ran out of fiber strands within two years, and the local folks managing the grant refused to install 4" conduit, and insisted on 2" conduit, so we could not pull another fiber cable
08:53 AM JT-Shop: first some company would have to connect to the end...
08:54 AM roycroft: i'm quite familiar with the stimulus grant fiber projects in western oregon, and they were all pretty sensible
08:55 AM roycroft: most of them were at least partially lit within a year of completion
08:55 AM roycroft: most of them were in rural areas that would not otherwise be able to afford to install the fiber
08:59 AM roycroft: as with most large government programs, not all of the stimulus ones were successful, but the btop grants were a great success
09:00 AM * JT-Shop wishes someone would light this one up
09:00 AM roycroft: yeah, it sounds like your local project was not as well thought-out as most
09:01 AM roycroft: btop grants generally require some local government investment, and that may be the problem with yours
09:02 AM roycroft: they way the grants work is that the feds fund the construction of the fiber plant, hand management over to local government, and require reserving 50% of the fiber for the feds to use or allocate as they will
09:03 AM roycroft: the intent is for the projects to be public-private partnerships, the public bit being the backbone fiber, and the private sector part generally being the last mile fiber plant and lighting the fiber
09:05 AM roycroft: our initial model was for the city whois fiber assets i manage would seek further grant monies to build out the fiber plant to the home, build a large meet me facility at the head end, and then find private partners to light and provision fiber services
09:05 AM roycroft: we had already invested ~$3 million on backbone fiber loops before the economy crashed
09:05 AM roycroft: those were in the core of the city
09:05 AM roycroft: (this is a city of 10k residents, btw)
09:06 AM roycroft: the btop grant brought the fiber to the outskirts
09:06 AM roycroft: we needed another $14 million to do the fiber to the home part, and since the economy crashed shortly after we started the project, that bit has sadly never happened
09:07 AM roycroft: we have leased out much of the fiber, though, and one of the fiber leases brought a new business to town that created a bunch of badly needed jobs, so that is great
09:08 AM JT-Shop: yea that sucks, we have ~30k in the county with the bulk in the city which has fiber
09:08 AM JT-Shop: yea new jobs is great
09:12 AM * JT-Shop wants to get some worm farming going...
10:00 AM skunkworks: JT-Shop: how did you setup git?
10:01 AM skunkworks: (like are you sharing a directory or using http? (for your local git repository you setup)
10:15 AM roycroft: i set up what i think is a somewhat interesting and useful git repository
10:15 AM roycroft: i work using multiple computers, and want to be able to move projects between them easily
10:15 AM roycroft: so i built a github virtual machine on my home network
10:16 AM roycroft: i use that as my master repository, and i git clone projects from there when i need to work on them
10:17 AM roycroft: and on that virtual machine i installed a utility called duplicity, which allows me to replicate the git repository to an offsite machine, and store the replicated data encrypted on that machine
10:17 AM roycroft: i just run the replication script four times/day, and am confident that i have a good, recent offsite backup
11:17 AM jthornton: skunkworks, I set it up on a local server... let me find my notes
11:27 AM Loetmichel: *MUHAHA* AM i an canada or what? Just on the commute home someone forced his car into the lane pretty rudely... next traffic light his frontman stops, gets out of the car, walks back: "hey, that was a jerk move, dont you think?" The jerk: "ehm. now that you mention it: yes it was. Sorry for that!" and the front guy goes back to his car and both drive off... that COULD have be a nice brawl
11:27 AM Loetmichel: right there... (and no, i am in germany :-)
11:32 AM likevinyl is now known as Guest46765
11:37 AM roycroft: that would only be canadian of both of them had repeatedly said "sohrry"
11:37 AM roycroft: just one of them is not quite canadian enough
11:37 AM jym: What?! No poutine?
11:37 AM jym: ...Eh
11:38 AM jym: I was in Canada for like two weeks and began ending every sentence with Eh
11:38 AM jym: know what I mena... eh
11:44 AM jthornton: Loetmichel, I printed the camera mount, had to rotate it first. Looks great except the X home switch wires come out the side so it hits them. I wonder if they put them in the wrong spot
11:44 AM Loetmichel: nopew
11:44 AM Loetmichel: same here
12:07 PM esch: jym: do they say ope in canada
12:07 PM jym: IDK, lol
12:07 PM esch: it's a thing in minnesota, like if you gotta get around someone in an isle
12:08 PM esch: heard some people from winnepeg do it too though
12:11 PM esch: I might be going to BC to install this machine I'm workin on soon, guess I'll find out for myself
12:11 PM esch: if I can figure out this stupid safety I/O anyway
12:12 PM roycroft: winnipeg is more like north dakota/minnesota than it is like the rest of canada
12:12 PM roycroft: a lot of scandanavian influence there
12:12 PM esch: ye
12:12 PM roycroft: although i haven't heard "you betcha" used in winnipeg
12:13 PM esch: I think that's strictly a MN/WI thing
12:13 PM roycroft: it's also a dakota thing
12:13 PM roycroft: at least eastern dakota
12:13 PM esch: ND is a lot of 'Oh ya'
12:13 PM esch: I'm from MN but lived in fargo for 6 years
12:14 PM roycroft: my ex is from grand forks
12:14 PM esch: can't say fargo like a normal person anymore
12:14 PM roycroft: i've spent a lot of time there
12:14 PM roycroft: the really funny thing is, she doesn't think she has an accent
12:15 PM esch: I only went up there a couple times but it's just a smaller fargo
12:15 PM esch: the older I get the worse it gets tbh
12:16 PM roycroft: well my ex moved to oregon to be with me
12:16 PM roycroft: in the end that didn't work out, hence the "ex" bit
12:16 PM roycroft: but a dozen of her friends and family have also moved here
12:16 PM roycroft: i guess north dakota is a good place to be from
12:16 PM esch: yeah not to live
12:17 PM roycroft: it's a good place to freeze :)
12:17 PM esch: for real
12:17 PM esch: -50 windchills
12:17 PM esch: don't miss that
12:17 PM esch: at least the trees here keep that shit at bay most of the winter
12:18 PM Loetmichel: hihi, had a talk with my new boss a couple hours ago... my old boss asked me today when i finish a project "that is laying on your desk for three weeks now"... (in reality its only one and a half week) and i answered with "WHEN I GET TO IT AND DONT GET INTERRUPTED EVERY 5 MINUTES!"
12:18 PM Loetmichel: apparently he said to the new boss he wants to fire me for that if the new boss doesent object... MUHAHA... i told the new boss: "if he wants to: PLEASE DO... but i dont think he will like what happens to his company once i am gone ;)" ... new boss agreed. :-)
01:12 PM JT-Shop: lol
04:10 PM Tom_L: afternoon
04:31 PM Deejay: gn8
04:32 PM Tom_L: l8r
04:37 PM * JT-Shop knocks off 1/2 hour early... the boss is not looking and I'm tired
04:40 PM Tom_L: retirement more work than working?
04:40 PM * infornography takes note
04:41 PM JT-Shop: lol, I'll not retire till I can't do anything
04:41 PM JT-Shop: got a new washer and dryer and of course everything has to be moved lol washer must be on the left and dryer on the right
04:41 PM JT-Shop: old setup was the opposite...
04:43 PM Tom_L: by choice?
04:44 PM Tom_L: you can reverse the doors usually
04:44 PM Tom_L: i went thru a couple front loaders until i decided they're a poor design and won't get anymore
04:45 PM JT-Shop: I'll look again but I doubt you can reverse the doors, these are LG the Sears is still running just loud when spin dry
04:46 PM Tom_L: i got a bearing kit for mine
04:46 PM Tom_L: i forget what brand
04:46 PM JT-Shop: I looked at mine once and decided I didn't want to work on it
04:47 PM Tom_L: they just don't make any appliance to last like they used to
04:48 PM Tom_L: https://partsdr.com/
04:48 PM Tom_L: i get stuff there sometimes
04:49 PM Tom_L: the mfg wanted to sell me the whole tub assembly so i got bearings from them instead
04:49 PM JT-Shop: the old ones are Kenmore
04:49 PM Tom_L: the kit came with a new drive shaft bearings and seals
04:50 PM Tom_L: i think my first set was kenmore and lasted over 25 yrs
04:51 PM Tom_L: i think these may be whirlpool
04:56 PM JT-Shop: I see from the parts there is a front counter weight, maybe it was loose dunno
04:57 PM JT-Shop: 96F but 36% so doesn't feel as hot
05:00 PM Tom_L: 91°F here
05:03 PM JT-Shop: https://www.searspartsdirect.com/product/cyky7l1qhw-0026-110/id-8181666
05:03 PM JT-Shop: that might have fixed it if I felt like taking it all apart lol
05:16 PM -!- #linuxcnc mode set to +v by ChanServ
05:16 PM cradek: that would be silly. you can get a used/working washer for $100.
05:18 PM JT-Shop: I could get a used car for $100 for my wife to drive but I won't...
05:18 PM cradek: ha
05:19 PM cradek: my washer and dryer were $100 each at the neighborhood used appliance shop, and they've lasted 8 years so far
05:19 PM Tom_L: yeah they wanted to sell me the whole tub too but i got the bearing kit from that site
05:19 PM cradek: I guess new ones cost $thousands? people are nuts.
05:20 PM cradek: they probably have wifi and touchscreens
05:20 PM Tom_L: downloadable phone app too
05:20 PM cradek: russian spam relays
05:20 PM JT-Shop: not seen any with wifi or touch screens... but my chicken coop has a touch screen
05:21 PM JT-Shop: my old ones still work and I'll find someone that can't afford a washer and dryer and give it to them
05:22 PM cradek: Download the Laundry - GE Appliances App.
05:22 PM cradek: The Laundry - GE Appliances App can be used on Apple or Android smart phones, and is available to download for free from the Apple App Store or Google Play. Once downloaded, open the App on your smart phone and Sign In or create a WiFi Connect account.
05:23 PM SpeedEvil: I would pay a modest sum extra for open-source hackable appliances.
05:23 PM cradek: If you have been using the Clean Speak feature using the communication cable between the washer and dryer, remove the cable and plug in each ConnectPlus / U+ Connect module.
05:24 PM cradek: LED Solid Light: The app is unable to locate the appliance in the GE Cloud.
05:24 PM cradek: sorry
05:28 PM SpeedEvil: https://www.amazon.co.uk/Samsung-RF56M9540SR-American-Freestanding-Freezer/dp/B074P53HVK/ref=sr_1_12?keywords=fridge+freezer&qid=1568672523&sr=8-12
05:29 PM cradek: £2,799
05:31 PM cradek: wow it has cameras inside!
05:31 PM SpeedEvil: To be fair - I do want a fridge with cameras inside.
05:32 PM SpeedEvil: - to answer the question 'how many days ago did I put X in' - without having to get up and go to the fridge.
05:32 PM SpeedEvil: But I don't want it that much, and realistically, it should add $100 tops to the price.
05:32 PM cradek: I kinda just assume that wouldn't work
05:33 PM cradek: it's often hard to read an expiration date with the object right in your hands
05:33 PM SpeedEvil: I mean - observe when it was put in fridge.
05:33 PM cradek: oh you think the cameras would record the past and let you play it back?
05:34 PM SpeedEvil: yeah - take a shot every time the door closes
05:34 PM cradek: you could sharpie the date on stuff you put in there for $1 in supplies
05:34 PM SpeedEvil: Yes, I could, but I won't.
05:34 PM SpeedEvil: Especially when tired.
05:34 PM cradek: then just sniff it, dates don't work anyway :-)
05:35 PM cradek: not the sharpie
05:35 PM cradek: the food
05:46 PM Tom_L: or both
05:55 PM SpeedEvil: https://www.ebay.co.uk/itm/Bosch-Hole-Saw-76mm-Multi-Construction-hole-saw-76mm-2608584767-Vat-receipt/111955945668 - I have recently purchased this. Which caused me to wonder if similar carbide bits for brazing were readily available.
05:56 PM SpeedEvil: I have been unable to find them on aliexpress/ebay as bits with carbide brazed onto them spam the results.
05:56 PM SpeedEvil: Something like ~4mm cubes.
05:58 PM Tom_L: https://www.castlebar.us/products/inserts-brazed/
05:59 PM Tom_L: search: carbide brazing inserts
05:59 PM Tom_L: maybe you can find something closer to home
06:00 PM SpeedEvil: Further, probbaly. I'm looking for 'it's probably carbide' grade.
06:01 PM SpeedEvil: Ah - inserts was the magic word.
06:01 PM SpeedEvil: https://www.aliexpress.com/item/32849928072.html - as one example.
06:02 PM Tom_L: http://www.carbideprocessors.com/saw-blades/carbide-saw-tips-for-retipping/
06:03 PM Tom_L: search: carbide saw tips
06:03 PM SpeedEvil: ah - that's another good one.
06:03 PM Tom_L: quite a few listings for that
06:04 PM Tom_L: https://www.alibaba.com/showroom/tungsten-carbide-saw-tips.html
06:30 PM _unreal_: I've always wanted a pile of carbide blade tips
06:30 PM _unreal_: heh
06:30 PM _unreal_: what did you get for christmas
06:31 PM Tom_L: coal
06:34 PM Rab: US $33-100 / Kiloampere
06:34 PM Rab: 5 Kiloamperes (Min. Order)
06:34 PM Rab: haha
07:37 PM _unreal_: milling my parts on my flip plate jig
07:37 PM _unreal_: working greate
07:37 PM _unreal_: I'll snap a photo some time
08:55 PM tiwake: anyone have suggestions for a bench power supply and oscilloscope?
08:57 PM Tom_L: rigol scopes seem cheap and popular
08:57 PM Tom_L: iirc skunkworks just got one
08:58 PM tiwake: thats the thing
08:58 PM Tom_L: fix up a pc psu for power unless you want something special
08:58 PM tiwake: there was an oscilloscope I was looking at in the past but I forget the name of it... but found out from IRC channels like this about the company
08:59 PM tiwake: Tom_L: needs to be constant current capable
08:59 PM Tom_L: k
08:59 PM Tom_L: i don't have a 'bench supply' as such
08:59 PM tiwake: 30 volts 30 amps... I'd like to be able to use it for anodizing every once in a while XD
09:02 PM Tom_L: https://nyctomachia.wordpress.com/2018/09/02/riglol-unlock-extra-features-on-rigol-oscilloscopes/
09:02 PM tiwake: riglol thats it
09:03 PM Tom_L: DS1054Z i think
09:03 PM Tom_L: or you can spend more and get the 100Mhz or you can unlock that one and get 100
09:04 PM tiwake: yeah
09:08 PM Tom_L: iirc they say it's got a different ADC chip over the 100 but it seems to work at 100
09:11 PM Rab: tiwake, I've been looking at Siglent scopes, particularly SDS1104X-E. Slightly more expensive than Rigol, somewhat better performance, hax available for certain models IIRC.
09:12 PM Tom_L: just depends what you need really
09:12 PM Tom_L: i don't need lab equipment
09:12 PM Tom_L: i do have an old phillips 100Mhz scope but seldom use it
09:14 PM Rab: I have several decent analog scopes...really hate the 'feel' of the digital ones I've used, but digital storage, protocol decoding, USB capture, etc etc are hard to beat.
09:15 PM Tom_L: yeah i was tempted to get a rigol too but i probably wouldn't use it much
09:16 PM Tom_L: i've got a saleae logic analyser which i wouldn't trade
09:17 PM tiwake: I'll probably be wanting one for when I build the controller for my hardinge CHNC
09:18 PM Tom_L: i know a few that have the clones and they say they work great too and will work with the saleae software
09:18 PM tiwake: I've used oscilliscopes for figuring out what is wrong for things in the past, but it was always borrowed or taken to a friends house who did have one
09:18 PM Tom_L: so if you don't want to shell out the bucks for an original...
09:20 PM Rab: Tom_L, I have several of the $10 clones, but I gave up on the Saleae software and use them with sigrok.
09:20 PM tiwake: ...like when the haas VF1 I had was crapping out... after a bunch of troubleshooting, pulled out the servo encoder and looked at the signal with a scope... it was putting out a dirty signal
09:21 PM Rab: Not the world's best LA, but definitely a bargain for $10.
09:21 PM Tom_L: tiwake yeah that's one thing the LA won't tell you
09:21 PM Tom_L: if the signal is dirty
09:22 PM tiwake: LA?
09:22 PM Tom_L: logic analyser
09:22 PM tiwake: oh
09:23 PM tiwake: well, thats a really important aspect of trouble shooting... heh... is the power clean, are the signals clean...
09:23 PM tiwake: capacitors go bad and muck things up
09:23 PM tiwake: or other things
09:24 PM Tom_L: right
09:24 PM Tom_L: if you're troubleshooting old junk a scope is probably a better choice
10:40 PM _unreal_: man that was complicated. but I just figured out how to get the 3d object milling offset :)
10:41 PM _unreal_: now milling a missing part that I had forgotten to add to an other part before. now milling in my multi part flipping jig :)
10:41 PM _unreal_: so happy
10:41 PM _unreal_: and testing my new milling bit in 3d mode. seems to be amazing
10:42 PM _unreal_: OH WIERD
10:42 PM _unreal_: my spindle motor just REVED wayyyyy up.
10:42 PM _unreal_: SHIT HAVING POWER ISSUES
10:43 PM _unreal_: HUM
10:43 PM _unreal_: lights flickered a few times
10:43 PM _unreal_: spindle motor stalled kind of but cnc never did I dont think?
10:51 PM _unreal_: ?
11:05 PM miss0r2: _unreal_ What are you doing stalling a spindle at this hour?
11:06 PM _unreal_: power outage ish
11:07 PM _unreal_: seems to have stopped.
11:07 PM _unreal_: I neven re-homed and zero'ed
11:07 PM _unreal_: clearly I lost a few steps
11:07 PM _unreal_: power flickered several times
11:07 PM _unreal_: my USP on my PC was going crazy
11:07 PM _unreal_: was really wierd. my spindle at one point spun WAY up high
11:08 PM _unreal_: prob increased RPM by 1/3 and already going max
11:15 PM miss0r2: :]
