12:04 AM Net|: https://netpipe.ca/aha/programs.tar.gz thats my stash of program source ment to be viewed as an archive
02:59 AM Deejay: moin
03:23 AM gloops: bit more work on the bandsaw today, when this final distraction is complete i can return to cnc work
04:04 AM XXCoder: gloops: lol thats fancy cnc machine
04:08 AM gloops: i only wanted to cut some log slices for signs, that quite a few people asked about, ended up taking 3 months to make a bandsaw lol
04:09 AM XXCoder: lol
04:09 AM XXCoder: serious though it might be foir very specific cnc thats rare? dunno
04:09 AM XXCoder: insane price for that thing
04:38 AM gloops: oh that router on ebay lol
04:38 AM XXCoder: or "router"
04:38 AM XXCoder: looks like just 2 screws motors
04:43 AM gloops: some square linear rails, leadscrews maybe salvageable - not for more than they cost new though
04:44 AM XXCoder: way more than new yeh
04:44 AM Loetmichel: link?
04:45 AM gloops: https://www.ebay.co.uk/itm/CNC-machine-140x107cm/173703435575?
04:45 AM XXCoder: im wrong
04:45 AM XXCoder: no motors
04:45 AM Loetmichel: $850 for THAT? ... good joke
04:47 AM gloops: id have it for parts, you could do something with the bits..ridiculous price though, start at 1p maybe go over £100
04:47 AM Loetmichel: leadscrews that hjave THAT much dirt on them are done for, rails the same. thats just a bit of scrap steel and alu now
04:48 AM Loetmichel: looks like it did a lot of stone milling
04:48 AM Loetmichel: maybe an engraver for tombstones or something from the looks of it
04:48 AM XXCoder: former engraver yeah
04:48 AM gloops: or been car spraying in the garage
04:50 AM gloops: https://www.ebay.co.uk/itm/CNC-machine-fully-working/183599237161?
04:50 AM syyl: obviously not a single fuck given
04:51 AM syyl: if he just had blown of all the dust with compressed air, that would increase the chance for a good price
04:51 AM gloops: even that for 300 - no spindle, may as well put the other 200 in and get a new one, with spindle
04:52 AM SpeedEvil: Might even be fine, you can't even tell it's not soft plastic dust
04:53 AM gloops: never know that old one, might be top quality parts, good rails are expensive, but still way too much
04:53 AM XXCoder: wonder if thats case of "wife told me to sell and I dont want to" pricing
04:53 AM gloops: he probably got that out of skip, googled cnc router prices and though yipee
04:55 AM sensille: what is that short rail for on Z?
04:57 AM gloops: not sure what it ever was, looking again - not a router idt
04:58 AM gloops: only x and y axis - plasma?
04:59 AM sensille: i mean the "fully working" link
05:01 AM gloops: hmm not sure, looks like hes been engraving stone - maybe spring load travel?
05:01 AM jthornton: morning
05:01 AM XXCoder: hey
05:38 AM Tom_L: 52F, Hi 51, Lo 23
05:38 AM Tom_L: looks like the next wave will be frozen
05:47 AM XXCoder: man how did he find so many rusty stuff lol https://www.youtube.com/watch?v=D_xk6XZ1pRc
05:47 AM XXCoder: I guess he looks around at jnkyard everyday
07:03 AM jthornton: like most putube videos it's probably staged
10:36 AM Vitran: I was hoping to get some info on the 7i64. What is the threshold voltage for the signal to be considered high/low and what is the hysteresis range. As far as I can tell, a signal above 5V will turn it on and the input signal can be up to 24V, but I do not know if it will turn on at 3.3V or what
10:44 AM cradek: the manual says 4v will turn the input on
10:45 AM cradek: pretty sure you should not count on it having hysteresis, it's just an opto
11:00 AM pcw_home: Yeah, very simple OPTO inputs, they drive a Schmitt trigger on the 7I64 but through the (always somewhat random) OPTO characteristics
11:06 AM pcw_home: I suspect 3.3V will turn it on since there is no shunt resistor on the 7I64 OPTOs but its near the threshold on the lowest gain bin OPTOs
11:06 AM fragalot: lol. local fuel station accidentally had one of their tanks filled with water rather than fuel
11:06 AM pcw_home: cheaper
11:06 AM fragalot: so far only 7 cars have been destroyed because of it freezing & bursting the lines
11:07 AM cradek: much better for the environment
11:07 AM fragalot: :)
11:10 AM pcw_home: seems like something that a specific hose connector type would eliminate ( there have been some very bad chemical explosions from similar mishaps )
11:11 AM gloops: water doesnt compress - if that is injected the engine will soon be kaput
11:11 AM fragalot: gloops: fuel doesn't compress either
11:11 AM fragalot: pcw_home: you'd think so. but at some point a tank got contaminated with water, and wound up at the fuel station
11:12 AM gloops: well dont come running to me with bent con rods
11:13 AM fragalot: \o/ score.
11:13 AM fragalot: just bought a near mint kaiser PA automatic boring head
12:23 PM Roguish: modern steam punk engine,,,,,,,,,,,,,
12:34 PM fragalot: Roguish: ha. :-)
12:41 PM Net|: https://www.thingiverse.com/thing:3317014
12:42 PM gregcnc: gloops water injection is as old as engines
12:43 PM gregcnc: just not in place of fuel
12:45 PM fragalot: gregcnc: depends on how hot said water is
12:45 PM gregcnc: hot?
12:46 PM fragalot: steam.
12:46 PM gregcnc: water injectionr, not steam injection
12:47 PM fragalot: same thing, just different temperature.
12:47 PM gregcnc: steam injection for internal combustion engine?
12:48 PM SpeedEvil: Six-cycle is a fun idea.
12:48 PM gregcnc: yeah they are all over the place
12:48 PM SpeedEvil: Delete cooling from IC engine add a steam stroke to remove heat.
12:48 PM fragalot: six cycle exists, used for diesel trains
12:49 PM fragalot: gregcnc: you inject the water into the engine to BECOME steam, which expands more than plain steam
12:49 PM gregcnc: so water or steam?
12:49 PM fragalot: both. starts as water, becomes steam.
12:50 PM SpeedEvil: https://en.wikipedia.org/wiki/Six-stroke_engine#Crower_six-stroke_engine
12:51 PM gregcnc: I know about the crower, all the top automakers are using that design......
12:54 PM syyl_: fragalot, thanks, money came in
12:56 PM gregcnc: https://en.wikipedia.org/wiki/Water_injection_(engine)
01:05 PM gregcnc: what does puppitast translat to?
01:11 PM ziper: does that actually work?
01:12 PM gregcnc: ??
01:12 PM ziper: the six-cycle water injection
01:13 PM sensille: gregcnc: dial test indicator?
01:13 PM gregcnc: I'm pretty sure testing proved it didn't
01:23 PM SpeedEvil: Who did the testing and if it was actually decent is another question.
01:23 PM ziper: it would be a 50 percent increase in friction, wouldn't it?
01:23 PM SpeedEvil: Landing rockets on their tails was not appreciably harder in 1990.
01:24 PM SpeedEvil: ziper: At least. But perhaps recovering some of the otherwise wasted exhaust heat.
01:25 PM ziper: How big does a steam turbine plant need to be to be competitive with diesel?
01:25 PM SpeedEvil: IIRC big diesel beats steam.
01:27 PM ziper: yeah, now that i think about some of those ship engines
01:31 PM * miss0r2 is doing his first 50/50 zink+nickel electroplating as we speak
01:31 PM miss0r2: Science, ladies and gentlemen!
01:33 PM gregcnc: https://paultan.org/2005/12/11/bmw-turbosteamer/
01:42 PM fragalot: syyl_: Thank you. :-) they've already seen a fair amount of use. been scraping like a madman today..
01:43 PM fragalot: syyl_: for maintenance - do you just pop 'm into an ultrasonic cleaner every now & again, or do they require something "more"?
01:43 PM fragalot: miss0r2: how's it going?
01:43 PM SpeedEvil: 'This results in reducing fuel consumption by 15 percent, and an additional 14 horsepower and 15 lb-ft of torque for BMW’s inline-4 1.8 litre engine. And it doesn’t cost you anything as it is recycled from the exhaust gas heat.' - yeah - because weight is free and causes no parasitic drag.
01:44 PM gregcnc: getting the last few g/kWh isn't easy
01:44 PM SpeedEvil: Indeed.
01:45 PM fragalot: SpeedEvil: you can mitigate some of that by using the exhaust gasses as a bubbler under the hull to reduce drag
01:45 PM SpeedEvil: :)
01:45 PM fragalot: (no, really)
01:45 PM SpeedEvil: The above was a car
01:45 PM fragalot: Ah.
01:48 PM FinboySlick: Not complex enough. Use waste exhaust/engine heat to drive a stirling engine.
01:49 PM FinboySlick: I think there were already some attempts at this.
01:49 PM SpeedEvil: yeah
01:49 PM SpeedEvil: the novel bit about the six-cycle was being able to dump the exhaust heat exchanger.
01:50 PM SpeedEvil: And not need an extra steam cylinder
01:50 PM SpeedEvil: The Crower anyway
01:50 PM SpeedEvil: the BMW one has a steam cylinder.
01:51 PM FinboySlick: Yeah, but you're still carrying water around, no?
01:51 PM SpeedEvil: Indeed.
01:52 PM fragalot: SpeedEvil: there are also ... what's that electronic equivalent of the stirling engine called again
01:52 PM fragalot: peltier
01:52 PM SpeedEvil: Unfortunately inefficient. 10% or so
01:52 PM gregcnc: peltier efficiency is pretty bad
01:52 PM SpeedEvil: and that also needs a large cooler
01:53 PM fragalot: yeah but it's still like 0.05% more than not regaining anything.
01:53 PM fragalot: and therefore TOTALLY worth it
01:53 PM FinboySlick: SpeedEvil: Well, on a car if you had efficient peltier you could always use the body or an underplate as a giant cooler.
01:53 PM fragalot: :D
01:53 PM gregcnc: not cheap or durable
01:53 PM fragalot: FinboySlick: or the existing coolant circuit?
01:54 PM FinboySlick: fragalot: I guess, though I think peltier sink temperature versus ideal engine run temperature might be difficult to harmonize.
01:55 PM fragalot: FinboySlick: well one end is on the host exhaust, the other is at ~90°C -- there should be a decent temperature differential there
01:56 PM FinboySlick: I was thinking efficiency maximization where you'd essentially insulate the entire block so that all waste heat would go to the peltier/stirling recuperator.
01:58 PM fragalot: now /THAT/ would be hard :-)
01:59 PM FinboySlick: Since you'd probably have a very narrow power/efficiency range. Might as well put all that work into fuel cells.
01:59 PM FinboySlick: I remember the Ballard days ;)
02:00 PM FinboySlick: Rumor has it they had their breakthrough using some Glad plastic bags (or something very similar) as a barrier. I don't think they ever revealed what it was though.
02:02 PM fragalot: I mean.. you are proposing to dump ~170kW of heat (assuming ALL inefficiency is counted as heat) through that poor little peltier
02:02 PM fragalot: (assuming my car, at ~36% effiency)
02:03 PM gregcnc: 50% of waste goes out the exhaust
02:03 PM FinboySlick: I was assuming a spherical cow in a vacuum.
02:03 PM FinboySlick: (that is, an efficient heat recuperation tech)
02:08 PM ziper: How does a bubbler under the hull reduce drag?
02:08 PM ziper: wouldnt the reduced density cause the hull to just sit lower in the water?
02:09 PM fragalot: it would, but - assuming that one YT video I saw is true - that is offset by the reduced friction
02:09 PM ziper: is it for displacement or planing hulls?
02:10 PM fragalot: they showcased it on an oil freighter
02:10 PM gregcnc: it's not a new idea.
02:10 PM * fragalot is not a nautical expert
02:10 PM fragalot: the video paired it with rotary pillar sails
02:11 PM _unreal_: That was wierd, xchat crashed... first time ever I think
02:12 PM ziper: https://patents.google.com/patent/US5456201A/en
02:12 PM ziper: I see, only a thin layer is bubbled
02:12 PM _unreal_: ok............. that @#$@#$ wierd... I cant load channel list with out crashing wtf?
02:13 PM FinboySlick: They got it all wrong. Just push the boat fast enough so that it can generate its own bubbles through supercavitation.
02:13 PM fragalot: _unreal_: just join #1000,0 for assistance
02:13 PM FinboySlick: mach2 oil tanker incoming.
02:13 PM ziper: hydrofoil tanker
02:13 PM gregcnc: yes
02:14 PM fragalot: FinboySlick: should be fun watching it crash into the pier
02:14 PM FinboySlick: I'm pretty sure it'd make it a few km past the pier.
02:15 PM fragalot: which part
02:15 PM FinboySlick: If it made it through mach2 in one piece, probably most of them.
02:15 PM _unreal_: figures I just got back been out most of the day shopping and stuff.. got the supplies I need so i can build the damn mold... and now its raining like hell outside
02:16 PM _unreal_: @%@#$ me
02:16 PM _unreal_: no matter how hard I tried I couldnt find my release wax for fiberglass layup... so I just went all the way to the FRP shop to get some.... get back now its raining.... yep
02:17 PM FinboySlick: _unreal_: Somebody figured out a buffer overflow in xchat and just hacked you with the channel list ;)
02:17 PM _unreal_: could
02:17 PM _unreal_: could
02:17 PM _unreal_: could be
02:17 PM ziper: _unreal_, you don't have an indoor shop?
02:17 PM _unreal_: for fiberglass
02:17 PM _unreal_: hell no
02:17 PM miss0r2: fragalot: misurable fail
02:17 PM fragalot: miss0r2: connected it backwards?
02:18 PM miss0r2: no
02:18 PM fragalot: forgot to hit "on" ?
02:18 PM _unreal_: fiberglass stuff smells bad. sticks up enclosed environments
02:18 PM fragalot: forgot to clean the parts?
02:18 PM miss0r2: But for some reason the beautiful even layer just didn't stick too well
02:18 PM miss0r2: no & no :)
02:18 PM fragalot: ah you forgot the intermediate layer
02:18 PM _unreal_: glass dust is stupid itchy..... not doing that inside
02:18 PM ziper: a barn, I mean
02:18 PM ziper: something with a roof
02:19 PM miss0r2: fragalot: well. nickel & zink should stick to steel on its own
02:19 PM _unreal_: dude I live in south florida
02:19 PM _unreal_: farms dont exist down here
02:20 PM _unreal_: open spaces.. etc.....
02:20 PM miss0r2: fragalot: AM I forgetting something in the process?
02:20 PM miss0r2: Don't leave me in suspense like this!
02:20 PM _unreal_: I have a nice backyard dont get me wrong..... but no space
02:21 PM jdh: move inland 20 miles
02:21 PM _unreal_: I am inland
02:21 PM _unreal_: I'm right on the edge of the everglades
02:21 PM fragalot: miss0r2: is the pH of the solution correct? agitated? what power are you pushing through this thing
02:21 PM jdh: bummer
02:22 PM miss0r2: fragalot: No idea. Yes, mildly & 5 volts limited at 1amp.
02:22 PM FinboySlick: Haha, just computed, that tanker (assuming a fairly average-sized one) would be about 4.6*10^14 joules of kinetic energy.
02:22 PM _unreal_: just to give you an idea of my area.... if you want to. google boca raton, as far west as you can go between glades rd/pallmetto rd... I'm in that general area
02:23 PM FinboySlick: A bit more than the median yield of modern nuclear weapons.
02:24 PM _unreal_: well I guess its time to have my last beer.
02:24 PM FinboySlick: _unreal_: Abom79 country.
02:24 PM _unreal_: ?
02:24 PM _unreal_: is that florida
02:25 PM ziper: that city is a testament to mans arrogance
02:25 PM FinboySlick: _unreal_: Yes. Beware the large man with a wrench.
02:26 PM ziper: suburbs are the lead pipes of the american empire
02:27 PM FinboySlick: And lead pipes are the best murder weapon in Clue.
02:27 PM fragalot: miss0r2: most common issue appears to be that "the part wasn't clean enough"
02:27 PM miss0r2: hmm. I guess that is an option, though, I *DID* etch it
02:29 PM _unreal_: speaking of etching... SOOOO pissed at my self.... I spent hours breadboarding to build a motor controller... I had 3, dont know what happend to the 3rd one that was 99% done just missing a few resistors......
02:30 PM _unreal_: so rebuilt one from scratch..... got the missing resistors for everything
02:31 PM _unreal_: and yesterday. I was doing a bunch of cleaning I had forgotten I had purchased high quality (from goodwill go figure) laminator... I could have printed a new board laminated it and etched it. BUT NO......... I said to my self. well shit I dont have an iron guess I wont be etching... "" I KNOW I'LL BREAD BOARD IT!""
02:32 PM _unreal_: moving stuff in the office came across it buried....... !!!!!! is.. that a..... ohhhhhh WTF..........
02:32 PM _unreal_: now I really need that beer
02:32 PM miss0r2: lol
02:33 PM _unreal_: its one of those laminators that can take items upto 1/8th thick....
02:33 PM FinboySlick: I'd love to understand electronics enough to build things like motor controllers.
02:33 PM Inline is now known as oleo
02:33 PM _unreal_: FinboySlick, its more or less just following schematics
02:34 PM FinboySlick: Well, that I could do but I wouldn't really understand what I'm doing.
02:34 PM _unreal_: trust me i DONT know all the laws of ohms etc..... I know enough to find online calculators etc... or bother people in the ##electronics channel :)
02:34 PM oleo is now known as Inline
02:35 PM FinboySlick: Well, I know the V=RI one.
02:35 PM FinboySlick: But the impedance and AC stuff really hurts my brain.
02:36 PM _unreal_: FinboySlick, I just got a 3com audrey today in the mail. got it off ebay for $19 USD +ship.... thats OMG especially for what it is... granted its 18+ years old now but they were killing me when they where new wanted one in the worst way... but they were selling for $500 then....
02:36 PM _unreal_: now its equal to like a pentium 1 166mhz
02:37 PM _unreal_: but that doesnt bother me any :) I have an other device that has the exact same cpu hardware in it.... but I can boot to different OS's
02:37 PM _unreal_: so I'm wondering if I can do some research and figure out what no one else could on how to get the thing to boot other os's
02:38 PM _unreal_: I'll laugh if I do. because no one else has.... sadly the best source for info on the @#$# damn things and may others is now gone only archive.org has it... linux-hacker.net :(
02:38 PM _unreal_: may she rest in piece
02:39 PM renesis: wtf is that thing unreal
02:42 PM Vitran: I have small massive news. I got the X axis and Z axis working on the lathe today! It is a Hardinge Superslant. Been a 3 year project
02:43 PM _unreal_: ren its like the iopener
02:43 PM _unreal_: same idea different x86 cpu
02:44 PM FinboySlick: Vitran: Congrats on that. It's a pretty neat piece of hardware.
02:46 PM ziper: how old are the PCs you guys run linux cnc on?
02:46 PM ziper: ancient, just obsolete, or current?
02:46 PM JT-Shop: Vitran: nice, does the super slant have the dual turrets?
02:46 PM JT-Shop: all the above
02:47 PM Tom_L: brrrr....
02:49 PM FinboySlick: https://www.youtube.com/watch?v=quABfe4Ev3s Educational :P
02:49 PM Tom_L: ziper mine is so old you have to crank it to get it started
02:51 PM JT-Shop: kick starter broken?
02:52 PM Tom_L: fraid so
02:53 PM JT-Shop: cold front made to your house?
02:54 PM ziper: no problem with performance?
02:54 PM Tom_L: 31
02:54 PM Tom_L: down to 23
02:54 PM Tom_L: it's on the way for sure
02:54 PM JT-Shop: 61°F here
02:55 PM JT-Shop: performance?
02:55 PM JT-Shop: in what way?
02:55 PM Tom_L: part of I 70 is closed
02:55 PM JT-Shop: snow?
02:56 PM Tom_L: not here but probably soon
02:56 PM Tom_L: up there yes
02:58 PM Tom_L: hopefully it will quit raining before it turns to snow here
02:59 PM _unreal_: 81F here :)
03:00 PM _unreal_: err no scratch that just raid so its now 76F outisde
03:00 PM _unreal_: rained
03:07 PM _unreal_: renesis, you live?
03:07 PM _unreal_: well time for more alcohal
03:07 PM renesis: i always do it live
03:08 PM _unreal_: was just wondering. you asked a Q I answered never saw a responce didnt know
03:25 PM gregcnc: ziper ancient, P3 900, 512mB, but it's pretty much maxed
03:26 PM Vitran: Back from food. It has a turret and tailstock. Turret and tailstock have 8 heads
03:26 PM gregcnc: twin turret tehn?
03:28 PM gregcnc: oh had to check, no X on the tailstock. what year is that?
03:29 PM JT-Shop2: Vitran: you got the turret working?
03:31 PM Vitran: <JT-Shop2> Not sure yet. It has been resting on a block of wood. I do know that the upper turret is leaking air like mad. Not sure why, but I do know it was doing that before
03:31 PM Vitran: I believe it was a broken o ring
03:33 PM JT-Shop2: yea my chnc turret and collet closer leak air at a huge rate even with all new o-rings and quad rings
03:35 PM JT-Shop2: does the turret look like mine? http://gnipsel.com/shop/hardinge/hardinge-gallery.xhtml
03:36 PM gloops: https://www.ebay.co.uk/itm/Vintage-BOSTON-SCALE-M-C-Co-COMPOUND-ANGLE-PLATE-TABLE-3360/323366229603?
03:37 PM gregcnc: https://www.youtube.com/watch?v=km6dBVd_Fhk
03:40 PM gloops: slighty beyond the prosumer
03:41 PM gregcnc: gloops you don't have a dozen 4-6 axis lathes in your shed?
03:42 PM XXCoder: everyone has couple of those rusting in back yard
03:42 PM gloops: not yet
03:44 PM gloops: someone round the corner works on a 5 axis lathe, he makes the stupidest looking small widget - same one, day in day out
03:45 PM gloops: well the machine makes them, he sits on his phone all day
03:45 PM XXCoder: thats moneymaker.
03:45 PM XXCoder: infinity of boring parts
03:45 PM XXCoder: yet long enough per part that can read book or play games or something
03:45 PM gloops: he always looks ready to drop - long stupid hours
03:51 PM XXCoder: geez
03:51 PM XXCoder: working all hours to get more money will evenually kill him
03:51 PM XXCoder: balance work and life
03:55 PM gloops: yeah, they do a killer shift pattern, like 3 nights, 2 earlies, 2 afternoons, 3 days off etc
03:56 PM XXCoder: thats people killer shift pattern.
03:56 PM gregcnc: that's terrible
03:56 PM XXCoder: I mean it in quite literal way
03:56 PM XXCoder: gonna go laters
03:56 PM gloops: youre better off working 1 shift regular
03:56 PM gloops: cya later
04:07 PM TurBoss: 0
04:27 PM Deejay: gn8
04:29 PM _unreal_: renesis, did you ever get into the iopener like devices?
04:38 PM Vitran: Older pics https://imgur.com/a/dKMqCaI, https://imgur.com/a/O9cLVxZ Really old pics https://imgur.com/a/7swJV
04:58 PM _unreal_: renesis,
06:19 PM Vitran: I am doing tuning of the axis. The jog functions seem to be a sawtooth jog. Is there no way to do a step function?
06:25 PM Vitran: Okey, figured it out.
06:26 PM Vitran: had the acceleration and top speed capped to 2, now 100 and working well.
07:11 PM _unreal_: OMG its crazy how many web sites are no longer around anymore
07:11 PM _unreal_: https://web.archive.org/web/20080323085336/http://www.taomc.com/studio_machines/egg_plotter.htm
07:27 PM ziper: thinkin bout dem pulsejets
08:14 PM norias: oi
08:14 PM norias: trying to learn how cnc works
08:14 PM norias: i got a book called "automatic control systems"
08:15 PM norias: should eventually get to PID controllers there
08:19 PM _unreal_: norias, what are you trying to learn?
08:19 PM norias: cnc systems from the ground up
08:20 PM _unreal_: ok but WHAT are you trying to learn
08:20 PM _unreal_: the hardware? the software
08:20 PM norias: yes
08:20 PM norias: :)
08:20 PM Rab: norias, commercial systems or DIY methods?
08:20 PM norias: Rab: commercial
08:20 PM _unreal_: That was going to be my next Q
08:20 PM norias: but i think i should have a passing familiarity of DIY
08:21 PM norias: i'm a machinist, by trade
08:21 PM norias: btw
08:21 PM _unreal_: norias, do you HAVE a commercial one or are you planning on working for a company with said machine and wwhich one?
08:21 PM _unreal_: they are all different in regards to how to control them
08:21 PM norias: so, the mechanical components are rather well known to me
08:21 PM norias: _unreal_: i'm sticking with mills, for now
08:21 PM _unreal_: palm to face..... ok then you are really only interested in the control/software side
08:22 PM norias: no
08:22 PM Rab: norias, here's a great resource: https://www.cnczone.com/forums/
08:22 PM _unreal_: :)
08:22 PM norias: Rab: thanks
08:22 PM _unreal_: hay rab I need to post some photos
08:22 PM Rab: _unreal_, orly
08:22 PM _unreal_: I got my splash mold done finally for my RPI lcd enclosure
08:22 PM norias: i'm going to start with how many windings of what sort of wire
08:22 PM norias: how that affects the motors
08:22 PM _unreal_: O.o
08:22 PM norias: through all the controls and software
08:22 PM _unreal_: wtf
08:23 PM norias: that's how i do things
08:23 PM norias: it works for me
08:23 PM _unreal_: why?
08:23 PM norias: i might want to make one
08:23 PM _unreal_: its called spec's
08:23 PM norias: if nothing else, everything i've learn so far has made me a better machinist
08:23 PM Rab: norias, as a machinist you may already be familiar with PM, but just in case: https://www.practicalmachinist.com/vb/
08:23 PM _unreal_: motors ounce inch rating per voltage etc....
08:23 PM norias: Rab: I dig PM
08:24 PM norias: _unreal_: what do you have against learning? :)
08:24 PM _unreal_: I'm not knocking it. just saying the useful gain of that knowlage is limited in regads to application
08:25 PM norias: eh, we'll see
08:25 PM Rab: Scroll down, lots of forums specific to various commercial controls/mfgs. Obviously forums don't make for a clear overview, but they're a great resource for chasing down esoteric details of interest.
08:25 PM _unreal_: including building. "specs" tell you the very details needed for build a machine using said motors.
08:26 PM _unreal_: rab somewhere in there are photos of the first machine I ever built
08:26 PM _unreal_: cnczone.com
08:26 PM _unreal_: freaking like 18 years ago
08:26 PM _unreal_: cnczone.com was very small back then
08:26 PM norias: i any of you ever read any of the Moore books?
08:27 PM Rab: norias, I don't think so.
08:27 PM norias: like "Foundations of Mechanical Accuracy" by Wayne R. Moore?
08:27 PM _unreal_: rab I just picked up a 3com audrey
08:27 PM Rab: Heard good things about that particular book, though.
08:27 PM norias: it's great
08:27 PM norias: good fun
08:28 PM norias: those guys were detail oriented
08:28 PM Rab: _unreal_, I hope you're having fun with it, but I have a horror of that old stuff. I used to have a bunch of iOpeners which were about the same thing, made many hardware modz.
08:29 PM Rab: Sent them all to e-waste.
08:29 PM _unreal_: Rab, get this
08:29 PM _unreal_: !!!!!
08:29 PM _unreal_: ewaste
08:29 PM _unreal_: you bastard
08:30 PM _unreal_: should have sent them to ebay waste
08:30 PM Rab: In Texas we say: basura
08:30 PM Rab: Ain't nobody got time for that
08:30 PM _unreal_: in anycase get this
08:30 PM _unreal_: so the 3com audrey
08:30 PM Rab: Plus for cheap or free you can get an old Stinkpad or other quality laptop that's 1000x better.
08:30 PM _unreal_: did you ever do anything with it?
08:31 PM Rab: _unreal_, nope, I've not seen one in person.
08:31 PM _unreal_: ok
08:31 PM _unreal_: in anycase
08:31 PM _unreal_: main problem with it is that is was lacking a "bios"
08:31 PM _unreal_: has a 16MB flashrom
08:32 PM _unreal_: flash/bios combo I guess
08:32 PM _unreal_: but it has the foot print on the motherboard for BIOS
08:32 PM _unreal_: just missing the header
08:32 PM _unreal_: so i also have an other device called the eznet 200. has the exact same hardware inside. same cpu chipsets EVERYTHING is the same 99%
08:32 PM _unreal_: but the eznet has a bios chip
08:34 PM _unreal_: I just ordered some plcc32 sockets, and compatable eeprom's (bios chips). When the get here I'm going to try dropping one of these chips into the audrey
08:34 PM _unreal_: I have a feeling it will boot
08:35 PM _unreal_: rab the audrey has a w49f002up12b chip in it
08:39 PM _unreal_: ?
08:40 PM Rab: _unreal_, are you getting a chip with the Audrey bios pre-flashed?
08:41 PM _unreal_: https://drive.google.com/open?id=1EMYguINfdBS1wTeoze2DFCxf3hYviQs4
08:41 PM _unreal_: there IS no chip
08:42 PM _unreal_: was never released, and linux-hacker.net is gone so I dont know
08:42 PM _unreal_: I dont know if anyone ever made a bios for it
08:42 PM Rab: I know, but you're going to populate the pads with a socket and blank bios chip? What will that do?
08:42 PM _unreal_: but as far as I can tell the companies that made the 2 devices used the same refrence design 99% the same
08:42 PM _unreal_: not a blank bios
08:42 PM _unreal_: I'm going to put a copy of the bios from the other system the eznet 200
08:43 PM _unreal_: they are 99% the same on the inside. a
08:43 PM _unreal_: all of the chips are the same. same cpu, same north or south bridge what ever it is. same super I/O chip and few others
08:43 PM _unreal_: even the ram chips are the same between the 2
08:44 PM _unreal_: wow I typed that out fast :)
08:44 PM _unreal_: So ya I'm going to take a copy of the bios for the eznet 200 put it on one of these 2 chips I just ordered. then for haha's put that chip in my eznet 200
08:45 PM _unreal_: if it post's, then I'm going to take that chip and put it in the audrey when I get the socket for the plcc32 done if not already by then.
08:46 PM _unreal_: the only thing I dont know at this point is the fact that is has that other chip
08:46 PM _unreal_: w49f002up12b
08:47 PM _unreal_: What I am wondering is how to read that mofo... see if I can get a copy of the "bios" from it
08:48 PM _unreal_: There is a little header near both the bios chip and that chip existing chip the w49xxx one have not looked closely yet but if the header goes those one or both of those then its likely an ICSP
08:48 PM _unreal_: What do you think of my splashmold?
08:48 PM _unreal_: wholy shit I type a lot
09:23 PM Tom_L: finally stopped to notice?
09:28 PM _unreal_: lol
09:45 PM _unreal_: good deal https://www.amazon.com/gp/product/B06XHKSVTG/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
10:20 PM flyback: https://github.com/keirf/FlashFloppy/blob/master/RELEASE_NOTES
10:21 PM flyback: another firmware for china gotek floppy emulators
10:21 PM flyback: this one is free
10:21 PM flyback: but the other one is worth the $10 also
10:21 PM flyback: BECAUSE I KNOW SOME OF YOU GUYS HERE HAVE OLD CNC MACHINES WITH FLOPPYS
10:21 PM flyback: WHY I MENTION IT HERE
10:21 PM flyback: BMCC
10:35 PM _unreal_: ?
10:35 PM * _unreal_ wonders who has a cnc with a floppy
