01:56 AM * Bleepshop debates whether to buy rebuild parts, a PID controller and a 1/2">ER20 shank for the router or just buy a watercooled ER20 spindle...
02:04 AM Bleepshop: XXCoder / roycroft : The CNC at work is now chewing up ~16x18x2 rough sawn oak slabs to 15x17x1.75 cutting boards in <7 minutes instead of the 20+ the post-processor software was doing.
02:06 AM Bleepshop: Looked like the gantry was gonna fly right off the end of the table. Which would be bad as it looks like it weighs >700kg.
02:07 AM Deejay: moin
03:43 AM t4nk_freenode: moin
03:44 AM t4nk_freenode: heh, saw some smoke from the corner of my eye a bit back
03:44 AM t4nk_freenode: from the darned stepper driver
03:45 AM t4nk_freenode: got scared, but it turned out to be a darned short in the dupont cables that came with the drivers
03:46 AM t4nk_freenode: probably because it's one giant ball of wires altogether, moving a lot
03:47 AM t4nk_freenode: but still... *brr* shorts in cables that are presumably good
03:48 AM t4nk_freenode: I ordered some spare drivers anyhow... I know myself
03:48 AM t4nk_freenode: might order some more steppers too, I feel like building something nice
05:22 AM Tom_L: morning
05:23 AM JT-Cave: morning
05:25 AM Tom_L: no more procrastinating... http://tom-itx.no-ip.biz:81/~webpage/temp/house/basement/tub_roughin1.jpg
05:31 AM JT-Cave: getting closer
05:32 AM JT-Cave: is that the original shower head?
05:37 AM Tom_L: yes
09:30 AM satiowadahc[m]: Someone on the Discord is having issues with the keyserver... anyone recall if any changes have been made to it lately?
11:26 AM unterhaus: there is a topic on one of the mailing lists about the keyserver, but I didn't read it
11:30 AM CaptHindsight[m]: the web client stopped letting you log in without verifying with the keyserver
11:30 AM CaptHindsight[m]: has been a few weeks since the change
11:31 AM CaptHindsight[m]: not sure what the point is of having two passwords, what is next, three passwords?
11:39 AM JT-Cave: retinal scan and dna sample
11:40 AM XXCoder: i only know one password. dont need more than that
11:48 AM unterhaus: isn't it your same password?
11:48 AM roycroft: 2fa can be very useful, and is much more secure than just a password
11:48 AM roycroft: unfortunately, it's almost universally implemented by requiring an sms message as the second factor
11:49 AM roycroft: and if you don't/can't text, you lose
11:49 AM unterhaus: work has an app, but I messed up install somehow and they call me and I have to type a number
11:50 AM unterhaus: I forget if text is an option, but they don't exactly make changing it an easy thing
11:51 AM XXCoder: roy one of goverment agencies had bot tht randomly gets facts from my history, and i had so much hard time with it lol
11:51 AM XXCoder: i sure as heck dont remember 3 addresses agi
11:51 AM roycroft: that comes from the credit bureaus
11:52 AM XXCoder: other one was birthdays for family. my brain just dont work with birthdays. i know nobody elses besides mine lol
11:52 AM roycroft: i always make those answers up for security questions
11:52 AM roycroft: my password manager keeps track of them
11:52 AM XXCoder: cant do that
11:52 AM XXCoder: they have data
11:53 AM XXCoder: websites sure, but it was phone call
11:53 AM roycroft: if it's tied to real data it's not very secure
11:53 AM roycroft: the point is to make sure it's *you* who is trying to access the site, not any random person who has your personal history/data
11:53 AM XXCoder: once again, not a site
11:54 AM XXCoder: goverment side bot builds database of facts related to me and asks me 3 random questions related to those
11:54 AM roycroft: s/trying to access thesite/communicating with them/
11:55 AM XXCoder: anyway it was horrible lol
11:55 AM roycroft: my experience is that most enhanced security mechanisms are not well thought out
11:56 AM XXCoder: usual sites that ask me for answers to be asked and answered later, i make up answers
11:56 AM roycroft: i do too, and i make them totally nonsensical
11:56 AM roycroft: q: what was the first concert you attended?
11:56 AM roycroft: a: orange milkshake turtle
11:57 AM XXCoder: i hate ones where you have to choose correct question. thats more secure, but i cant remember worth crap
11:57 AM roycroft: q: what is your mother's maiden name?
11:57 AM XXCoder: i just screenshot my questions and answers and save em
11:57 AM CaptHindsight[m]: if you were to hide money, where would you hide it?
11:57 AM roycroft: a: 845 - 23 = 999
11:57 AM roycroft: stuff like that
11:57 AM XXCoder: lol
11:57 AM roycroft: i keep it all in my password manager
11:57 AM roycroft: so when i contact the site i can pull up the answers i gave for that site
11:58 AM Tom_L: what's the password to open the file that has my passwords in it?
11:58 AM roycroft: i have a very long passphrase for that
11:58 AM CaptHindsight[m]: first school, favorite teacher, first pet....
11:58 AM roycroft: and i have it printed out and stored in my safe deposit box, in case i go senile all of a sudden
11:58 AM Tom_L: i had no favorite teacher!
11:58 AM CaptHindsight[m]: what is this some sort of voluntary info collection?
11:58 AM XXCoder: first school, school of hard knocks
11:59 AM roycroft: i don't mind the security question stuff
11:59 AM Tom_L: so for cutting off abs fittings for a drain the rotary makes damn nice square ends
11:59 AM roycroft: but providing real answers defeats the purpose of it
11:59 AM CaptHindsight[m]: we had a bank that asked us to only use windows to access the online services
11:59 AM roycroft: that's a pretty fancy, expensive pipe cutter
12:00 PM Tom_L: and no friggin saw cut burrs to clean off
12:00 PM XXCoder: roy know whats worse? site with nasty 2fa system caps password at 8 charactors
12:00 PM roycroft: my hall sensor is due to arrive tomorrow
12:01 PM CaptHindsight[m]: must be named after someone
12:01 PM roycroft: good timing - i'm going to shoot paint on the junction box for my mill today
12:01 PM CaptHindsight[m]: why would you want to sense a hall?
12:01 PM Tom_L: to make a clean escape
12:01 PM roycroft: edwin hall discovered the hall effect
12:01 PM XXCoder: yep
12:01 PM XXCoder: faster than me lol
12:02 PM CaptHindsight[m]: like Barb Striesand?
12:02 PM roycroft: i used to know that but had forgotten
12:02 PM roycroft: i already had a wikipedia window open though
12:02 PM XXCoder: or Alessandro Volta
12:02 PM XXCoder: guess what is named after that guy
12:03 PM Tom_L: the watt?
12:03 PM CaptHindsight[m]: the Chevy Volt?
12:03 PM XXCoder: nope and.... probably? lol
12:03 PM CaptHindsight[m]: it was Charlie Watt
12:04 PM CaptHindsight[m]: Andy Ampere
12:04 PM XXCoder: watts up
12:04 PM CaptHindsight[m]: Georg Ohm
12:05 PM CaptHindsight[m]: a german invention
12:05 PM Tom_L: XXCoder, was that his first and middle name? and doc the last?
12:05 PM CaptHindsight[m]: resistance is futile
12:05 PM XXCoder: lol tom
12:05 PM roycroft: futility is futile
12:06 PM unterhaus: I set up first elementary school as a security question because I figured I could look it up, but they got rid of that school
12:07 PM unterhaus: they also tore down our house and put up mcmansions
12:07 PM unterhaus: ^possibly not the same people
12:08 PM * roycroft should head out to the shop and get some work done
12:08 PM Tom_L: well at least one of us should
12:08 PM Tom_L: i'll let that be you
12:08 PM roycroft: a question, first, about rare earth magnets
12:09 PM roycroft: are they at all machinable?
12:09 PM Tom_L: i have my doubts
12:09 PM Tom_L: they are kinda brittle
12:09 PM roycroft: i'm thinking probably not
12:09 PM XXCoder: maybe similiar method as you do with rocks
12:09 PM Tom_L: might screw up the magnetism too
12:09 PM roycroft: i need to embed one in a gear shaft
12:09 PM unterhaus: they rust really badly
12:09 PM CaptHindsight[m]: powder with binder (epoxy)
12:09 PM XXCoder: use grinder miller, and tons water
12:09 PM roycroft: it would be nice if it were rounded over to be flush with the shaft
12:10 PM roycroft: but the edges could stick out a bit and it would be ok
12:10 PM roycroft: it would just not look nice
12:10 PM unterhaus: the maganets on our linear motors rusted after 20 years and that was a real pain to fix
12:10 PM roycroft: but it will be covered up
12:10 PM unterhaus: essentially required new linear motors
12:10 PM roycroft: this is for my hall effect sensor
12:10 PM * Tom_L thinks CaptHindsight[m] thinks the whole world is held to gether with some polymer or poxy :)
12:10 PM CaptHindsight[m]: iron core linear?
12:11 PM CaptHindsight[m]: it is
12:11 PM Tom_L: heh
12:11 PM roycroft: and yes, that's what i thought rare earth magnets were - metal powder with an epoxy binder
12:12 PM unterhaus: once the coating is gone, I don't think you can stop the corrosion
12:12 PM unterhaus: have to get them molded in the right shape
12:12 PM XXCoder: https://www.youtube.com/watch?v=tz9vW3Vsr4U
12:12 PM CaptHindsight[m]: also sintered powder https://www.duramag.com/neodymium-magnets-ndfeb/neodymium-magnet-manufacturing-method/
12:12 PM XXCoder: unterhaus: wonder if can use nonreactive gas enclosure then re-coat it before using
12:12 PM roycroft: i'll just epoxy the magnet into the shaft and let the edges stick out
12:13 PM XXCoder: roy yeah seems best
12:13 PM unterhaus: obviously the magnet manufacturers can do it
12:13 PM roycroft: i bought a spare gear shaft for this, because i want to use my milling machine to bore the hole for the magnet, and the shaft is part of the milling machine
12:13 PM CaptHindsight[m]: "the brick magnets from the rubber mold method are usually squared on large grinders and then sliced to the final geometry"
12:13 PM roycroft: i could mess it up and still be ok
12:13 PM roycroft: but i'd rather not mess it up
12:14 PM CaptHindsight[m]: just don't put them up your nose
12:14 PM unterhaus: I don't know, I knew someone that put everything up his nose /cheech and chong
12:14 PM * roycroft tries to keep his body parts from getting in between a rare earth magnet and materials the magnet has the hots for
12:14 PM CaptHindsight[m]: https://www.extremetech.com/extreme/308475-astrophysicist-tries-to-build-anti-coronavirus-wearable-ends-up-with-magnets-lodged-in-nose
12:15 PM roycroft: they tend to be very persistent when they find something they like
12:16 PM unterhaus: there was a certain amount of comedy when we went to a generator manufacturer and they proudly showed us their new permanent magnet generator
12:16 PM unterhaus: The radius at which you could keep the two pieces from going together was about a foot
12:16 PM unterhaus: closer than that and it took two people to separate
12:18 PM XXCoder: capt lol interesting
12:19 PM unterhaus: I think you need weaker magnets if you are going to put them in your nose
12:19 PM XXCoder: he needed some field strength for sensor to trigger before he touches nose
12:23 PM CaptHindsight[m]: just say no
12:24 PM unterhaus: can't say nose without "no"
12:31 PM unterhaus: the whole thing about touching your face was overblown, it seems
12:32 PM XXCoder: digging for gold however...
12:33 PM unterhaus: never goes out of style
01:57 PM Bleepshop: Well, neodymium is going up in price to the point it would be worth digging for. ;D
01:59 PM * Bleepshop is still debating rebuild the Porter Cable 7518 cores, adding a PID controller and a 1/2">ER20 adapter of just swap the whole mess out for a watercooled ER20 spindle.
02:03 PM Bleepshop: Or should I drop the $100 for parts, rebuild the pair of 7518s cores, sell them for ~$300 each, buy the watercooled spindle and pretty much break even. LOL
02:04 PM roycroft: the problem is that you have to move to china to dig for it
02:04 PM roycroft: or, iirc, afghanistan
02:04 PM roycroft: there's only a tiny amount of neodymium in north america, and it's hard to get to
02:05 PM roycroft: as to your musing, my old router table had a 7518 motor in it
02:05 PM Bleepshop: Roedy: Or an Australian astrophysicist's nose. LOL
02:05 PM roycroft: when i built my new one i bought an 80mm er20 water-cooled spindle
02:05 PM Bleepshop: Damn nick completion.
02:05 PM roycroft: and i could not be happier with it
02:05 PM roycroft: not to mention i have my 7518 back as a hand-held router
02:06 PM Bleepshop: Want to buy another pair? They're about to get new bearings and brushes.
02:06 PM roycroft: i got a water-cooled spindle because it is a router table, not cnc router, and all the dust goes straight down towards the spindle when i have the extractor on
02:07 PM roycroft: the one i have i've had since the early '80s, and it still works like new
02:07 PM roycroft: if it ever dies, it's time to get a festool
02:07 PM Bleepshop: I'm thinking I can sleeve the spindle and run the dust collection right up the side of the can then.
02:08 PM roycroft: so i don't know how closely you've been following my discussion of my new cnc router build, but i don't have room to add a cnc router to my shop
02:09 PM roycroft: i do have a big router table whose surface is large enough for a cnc router to sit on top
02:09 PM roycroft: i've decided to build the cnc router into the router table
02:09 PM Bleepshop: I just wish they did square frame watercooled with the mounting lugs so I oculd drill/tap my backplate and bolt it on.
02:09 PM roycroft: such that i can use it as both a conventional router table with the spindle underneath and a cnc router with the spindle overhead
02:10 PM roycroft: i'll use another of the 80mm spindles for the overhead part
02:10 PM Bleepshop: Don't Don't let the toolpaths cross. LOL
02:10 PM roycroft: and i figure i can use the same vfd for both spindles, as long as i build in the proper safety lockouts to ensure that i don't blow up the vfd while switching from one to the other
02:11 PM roycroft: there will be a spoilboard that goes on the router table when it's to be used with the overhead spindle
02:14 PM Bleepshop: roycroft: I'm looking at a kit like one of these. https://www.amazon.com/Spindle-Inverter-Engraving-Milling-Cutting/dp/B073TRP92V/
02:16 PM Bleepshop: I eventually want to find some >18mm 6061 plate and cut new X/Y plates so I can get more than 2" of Z on this machine.
02:43 PM JT-Shop: it's amazing how much better a worm and worm wheel work when you take the lumps off the teeth from tossing the gears around
02:44 PM JT-Shop: time for clean up on aisle 2
02:44 PM Tom_L: working better now?
02:45 PM Tom_L: all back in once chinese lump?
02:49 PM Tom_L: went to install the surround, it was cracked, took it back for another, it was cracked, no more available in town.
02:49 PM Tom_L: 3 arriving wednesday, maybe 1 of 3 will be good
02:49 PM JT-Shop: aye, it had dings on both the worm and the gear so impossible to get backlash out, now smooth and no backlash
02:49 PM Tom_L: nice
02:49 PM Tom_L: glad it worked out
02:50 PM JT-Shop: I had to use my gear puller to get the gear off the shaft but the rest was pretty easy
02:50 PM Tom_L: it certainly wasn't made for continuous use
02:50 PM JT-Shop: oh the shaft lock was a bit rusty lol
02:51 PM Tom_L: would be nice if the input shaft had a bushing or something
02:51 PM JT-Shop: some rust free and T-9 took care of that
02:51 PM JT-Shop: on the back side?
02:51 PM Tom_L: on the crank
02:51 PM JT-Shop: or the worm shaft
02:51 PM JT-Shop: yeah it was a bit sloppy of a fit
02:52 PM Tom_L: makes trimming abs drain nice :) nice smooth ends
02:53 PM Tom_L: was kindof an afterthought... but mixing work n play isn't so bad
02:53 PM Tom_L: i had to cut the trap etc out because it wasn't deep enough for the new shower
02:59 PM JT-Shop: which surround are you using?
03:00 PM Tom_L: something she picked out from HD
03:00 PM Tom_L: imported by Kohler
03:01 PM Tom_L: certainly not the quality the one i took out
03:04 PM Tom_L: i'm not finding it on their site but i'm only halfway awake
03:06 PM Tom_L: https://www.homedepot.com/p/STERLING-STORE-30-in-x-60-in-Single-Threshold-Left-Hand-Shower-Base-with-Shower-Walls-and-10-Piece-Accessory-Kit-in-White-72170710-0-10/303161780
03:06 PM Tom_L: that might be it
03:06 PM Tom_L: the boys didn't want a tub this time and they used that one the most
03:08 PM Tom_L: the last one was a one piece and i had it dropped down the stair hole before the stairs were put in when i dug the basement
03:08 PM Tom_L: it's not a one piece now.
03:09 PM JT-Shop: 4 piece this time
03:16 PM Tom_L: yes
03:16 PM Tom_L: plumbing is done, just waiting on parts
03:16 PM JT-Shop: I put this one in https://www.homedepot.com/p/American-Standard-Ovation-Curved-30-in-x-60-in-x-72-in-3-piece-Direct-to-Stud-Alcove-Shower-Wall-in-Arctic-White-2699-SW-011/203978460
03:16 PM JT-Shop: https://www.homedepot.com/p/American-Standard-Ovation-60-in-x-72-in-Framed-Sliding-Shower-Door-in-Satin-Nickel-and-Clear-Glass-AM00560-400-295/203978469
03:16 PM Tom_L: i'm not sure they had that in the store
03:19 PM Tom_L: got a few more bumps and scrapes now
03:19 PM Tom_L: not quite as young as i was on the first one
03:34 PM JT-Shop: I hear that
03:39 PM * Bleepshop is currently trying to excavate a hole for the new power pole for the workshop. Through clay, Pinion tree roots and volcanic ejecta from way back when the caldera blew it's top.
03:41 PM Bleepshop: Shovel wants to bounce of fold, I can hammer in rebar ~12" and have to put a chain on it to pull it back up and a homemade 6" augur in a 1/2" drill has gotten me ~7" in 45 minutes. LOL
03:57 PM JT-Shop: I use my Hilti TE 76 hammer drill with a spade bit
03:58 PM JT-Shop: it's a beast
04:04 PM Bleepshop: I just tried to swiss cheese the hole with the hammer drill in a close set pattern. Got me another inch. LOL
04:04 PM CloudEvil: Bleepshop: pressure washer can be a useful tool in some soils.
04:04 PM Bleepshop: CloudEvil: Hard clay + flour fine sand.
04:05 PM Bleepshop: Plus the tree roots, rocks and buried beer bottles. LOL
04:06 PM Bleepshop: CloudEvil: If you ever did pottery think unfired, almost dried out B-mix.
04:07 PM Bleepshop: I'm using the shopvac for cleaning the hole out because of the diameter and the fineness of this when it finallly gives up.
04:27 PM JT-Shop: Bleepshop, that sounds pretty painful...
04:40 PM roycroft: i would drop a benjamin and rent a power auger for half a day
04:48 PM JT-Shop: bandsaw is clean and back together with clean coolant tank...
04:48 PM * JT-Shop calls it a day
04:49 PM Tom_L: ahmen
04:49 PM Bleepshop: I just welded a bit of old bedframe [the bit that holds the caster on] to a chunk of 1/2" bar stock and called it a 4" spade bit. And it works quite well. LOL
04:49 PM roycroft: My metal bandsaw does not have a coolant tank, but i want a smaller one for my router table, so I think I'll move the router table coolant system to the band saw and get the new system for the router table
04:50 PM roycroft: bed frames tend to be really hard metal
04:50 PM roycroft: if you're just going to cut and grind and weld on them they're great to work with
04:50 PM roycroft: if you're going to machine them, not so much
04:51 PM roycroft: I should say, they tend to be variable metal, with soft spots and hard spots, and no way to predict what you're getting yourself into
04:51 PM Bleepshop: That's why I grabbed that piece. I figured it waas that of a piece of 18 wheeler spring and I didn't feel like spending 4 hours to get the same shape. xD
04:52 PM Bleepshop: roycroft: I grab the old institutional ones where they were designed to be recycled into tanks for WW3. LOL
04:53 PM Tom_L: ww3 will be cyber and virus
04:53 PM roycroft: the thing is, they're mostly made of recycled steel, which is what makes them so variable
04:53 PM JT-Shop: ww3 has been going on for 2 years
04:54 PM JT-Shop: recycled steel is almost all steel...
04:56 PM * JT-Shop worked for Florida Steel a few decades ago...
04:59 PM Bleepshop: JT-Shop: This stuff is all pre 1985. I pick my bedframes out of the scrap metal bin at Habitat Restore with care. LOL
05:00 PM JT-Shop: I still need to find a place for my ancient Sears tool box with bad rollers
05:00 PM JT-Shop: what does 85 have to do with steel?
05:03 PM JT-Shop: maybe I need to fit new wheels on the tool box, I think I bought it in the mid 70's
05:08 PM Tom_L: you bought it today would it last that long now?
05:09 PM roycroft: not if it were from sears
05:09 PM roycroft: or made by craftsman, whoever they are not
05:09 PM JT-Shop: the tool boxes I got from Lowes seem pretty nice
05:09 PM roycroft: but if it were mac or snap-on or blue point or waterloo it would last 50 years
05:10 PM roycroft: or kennedy, of course
05:10 PM JT-Shop: I have one Kennedy tool box
05:10 PM roycroft: I have a kennedy stack
05:10 PM roycroft: I'd like another one, but I can't afford it and I don't have room for another one
05:10 PM pcw-home: Hey JT: dont ban VladCronos, He can get assembled boards for less than 1/2 what I pay just for materials He's got to be some kind of genius :-)
05:12 PM JT-Shop: lol
05:14 PM JT-Shop: pcw-home, any relief on the chip situation?
05:16 PM pcw-home: no, its pretty bad, I'm working on redesigning some cards to use Efinix FPGAs rather than Xilinx
05:18 PM JT-Shop: is the Efinix FPGA available?
05:19 PM pcw-home: Multiple Xilinx parts show >52 week leads times currently
05:19 PM JT-Shop: ouch
05:19 PM pcw-home: Yes, Efinix is ~4-8 weeks
05:19 PM JT-Shop: that's a lot better for sure
05:20 PM JT-Shop: will the Efinix change the mesaflash?
05:20 PM pcw-home: Yes mesaflash will need changes for Efinix based cards
05:20 PM JT-Shop: ok
05:21 PM JT-Shop: the Ti1000 looks like a beast of a chip
05:22 PM JT-Shop: 969,408 Logic Elements (LEs)
05:22 PM pcw-home: Not major but things like fallback are different
05:22 PM JT-Shop: ok, I don't think I've used fallback
05:23 PM pcw-home: The TI chips are not useful unfortunately because they dont have much GPIO
05:23 PM JT-Shop: using the Trion FPGA?
05:23 PM pcw-home: Yes, working with the Trion chips (the toolchain is a lot cruder than Xilinx)
05:24 PM JT-Shop: that adds to the fun
05:24 PM pcw-home: Yep I did get a 7I96 config to compile (with a day of editing the source)
05:25 PM JT-Shop: sweet
05:26 PM pcw-home: it fits easily on the T13 part (with more room to spare than the XC6SLX9)
05:26 PM JT-Shop: cool
05:27 PM pcw-home: Next step is to test a config on their devel board
05:28 PM JT-Shop: that sounds like fun
05:28 PM pcw-home: Disadvantage is that the chips are a bit slower then the Spartan6's
05:29 PM JT-Shop: will that change the max step rate?
05:30 PM pcw-home: Not much, I may have to reduce the ClockLow to 75 MHz instead of 100 MHz so that drops the max step rate to say 9 MHz
05:31 PM JT-Shop: faster than most drives can take I assume
05:31 PM JT-Shop: looks like DigiKey has 3 out of 4 T13's in stock
05:32 PM pcw-home: I only just got a config to compile yesterday so I may be able to tweak things (yes faster than most drives))
05:33 PM pcw-home: Yeah I will probably buy direct, but the fact the Digikey has any is pretty hopeful
05:33 PM JT-Shop: aye that is a good sign
05:34 PM pcw-home: One of Efinix'x larger investors is Xilinx...
05:35 PM pcw-home: though they are a Chinese company
05:35 PM JT-Shop: trying to expand I assume
05:36 PM pcw-home: Xilinx stock is really high now (this chip shortage is great for the chip makers, prices are crazy high)
05:39 PM JT-Shop: on a personal note Rusty (my truck) is 20 years old and I've been waiting on a new Ridgeline since March 31st it has been built and is in transit finally
05:41 PM roycroft: my pickup was made in 1987
05:42 PM roycroft: i've had it for almost 20 years, though
05:42 PM Bleepshop: JT-Shop: It's about when the bedframes went from decent steel with mill roller marks and went to the folded crap.
05:42 PM pcw-home: Glad we don't need a new car
05:43 PM Bleepshop: pcw-home: Are you running HostMot on a random Spartan 6 board?
05:43 PM JT-Shop: roycroft, I wish I kept my `81 C10 Custom Deluxe it was a great truck
05:44 PM JT-Shop: back in March Honda had incentives for the Ridgeline but no trucks!
05:45 PM * Bleepshop has an RV901T board squirreled away for future use.
05:46 PM JT-Shop: we will be in good shape for vehicles for a long time when I get the 2022 Ridgeline
05:46 PM pcw-home: Bleepshop: Most of our current FPGA motion cards use Spartan6 FPGAs
05:47 PM roycroft: mine is a little toyota
05:48 PM roycroft: it works ok, but it is small
05:48 PM roycroft: it's just a 1/2 ton truck
05:48 PM roycroft: but i do have a 3/4 ton chevy van that i use when hauling heavy stuff
05:48 PM roycroft: or stuff that needs to stay dry
05:49 PM Bleepshop: pcw-home: I've got one of these and I've tracked down DIN rail mount IDC50<>Screw-terminal breakouts to try and build an almost real PLC for my CNC.
05:49 PM Bleepshop: https://github.com/q3k/chubby75/tree/master/rv901t
05:49 PM roycroft: having said it's a 1/2 ton truck, i've hauled a half yard of rock in it many, many times, which weighs about 3/4 of a ton
05:50 PM * roycroft is having a semi-scary afternoon
05:50 PM roycroft: i am ugrading mac os on my imac, and possibly in my macbook pro as well
05:50 PM Bleepshop: roycroft: That's usually 1/2 ton + 3 280 linebackers in the cab so you were within ratings. ;D
05:51 PM roycroft: the frame of my van is identical that the chevy one ton
05:51 PM Bleepshop: roycroft: See you next week when you've gotten the bugs ironed out ?
05:51 PM roycroft: the big difference being the one ton has dual wheels on the rear
05:51 PM roycroft: bleepshop: i'm ugrading from catalina to big sur
05:52 PM roycroft: monterey is the current os
05:52 PM roycroft: so i'm going from two versions ago to one version ago
05:52 PM Bleepshop: roycroft: Hell, I better tell you "Merry Christmas" now. ;D
05:52 PM roycroft: and i've been testing my apps over the last few months on a big sur virtual machine
05:53 PM roycroft: the only problem was with vmware fusion, and i just bought and installed an upgrade to that
05:53 PM roycroft: but if it all blows up, i'll just restore from time machine
05:53 PM roycroft: and go back to catalina
05:54 PM * roycroft is not worried, but any major upgrade does involve some risk, and so is somewhat scary
05:54 PM Tom_L: JT-Shop, at least they didn't have to label it a 2023
05:55 PM Tom_L: ... comes with all the features of a 2022..
05:56 PM roycroft: i got my junction box painted for the mill today, so after the paint cures i'll be able to assemble that and get the machine working again
05:56 PM Tom_L: hopefully we're set for a while too if she can quit cracking windows
05:56 PM roycroft: which is good, because i need to do some milling on the heat sinks for my gecko rives
05:56 PM roycroft: drives
05:57 PM roycroft: the metal stock and the drawing have been sitting in my shop for two weeks
05:59 PM roycroft: ok, time to disappear for a bit while the os upgrade installs
08:26 PM sadara is now known as crash
08:26 PM crash is now known as sadara_
08:27 PM sadara_ is now known as sadara
09:04 PM sadara: does anyone have a working configure for a 7c80 or 7c81?
09:11 PM Tom_L: do you have the spi working?
09:11 PM sadara: yes
09:11 PM sadara: mesaflash works correctly
09:11 PM Tom_L: that's a good first step
09:12 PM Tom_L: did you do a readhmid?
09:12 PM sadara: yes
09:12 PM pcw-home: You should be able to take a config for a similar card (say created by pncconf) and change the driver and card name
09:13 PM Tom_L: i wasn't sure you had any configs for it
09:13 PM Tom_L: or if it came with one loaded
09:13 PM sadara: which similar card would you recommend?
09:13 PM pcw-home: a 7I96 is close
09:14 PM sadara: I'm trying to set up a 7c80 + 7i85
09:14 PM sadara: pcw-home, thanks
09:14 PM pcw-home: at least the stepgen and output setup is identical, the inputs need to be done by hand editing the hal file
09:14 PM sadara: Will try that
09:35 PM enleth: pcw-home: have you given any attention to Lattice FPGAs as potential Spartan6 replacements?
09:35 PM enleth: pcw-home: some of them are supported by a fully open toolchain
09:38 PM enleth: specifically, the ECP5 series is supported by Symbiflow/yosys
09:44 PM pcw-home: lattice, Intel(Altera), Xilinx all unavailable
09:46 PM pcw-home: Actually the Efinix toolchain is not free but seems to be built of open source command line tools (all except for bitfile generation probably)
10:54 PM sadara: does anyone know the original qtdragon github address?
11:02 PM sadara: what are peoples thoughts on Stepper + encoders these days?
