[02:19:47] <PetefromTn_> jeez man I go eat some dinner and work out in the shop and this place just DIES!! ;)
[02:21:09] <Wolf_> all your fault
[02:21:24] <Wolf_> and amazon prime is great
[02:21:28] <PetefromTn_> apparently
[02:21:41] <PetefromTn_> does this prime thing INCLUDE the TV part?
[02:21:58] <Wolf_> yeah
[02:22:27] <Wolf_> I’m watching back to the future on amazon prime vid via a Roku right now
[02:22:46] <PetefromTn_> nice
[02:23:01] <PetefromTn_> we have had netflix
[02:23:11] <PetefromTn_> but I understand amazon is decent as well.
[02:23:52] <Wolf_> it is, the few bucks to upgrade to overnight shipping has saved my ass a couple times on jobs
[02:24:53] <PetefromTn_> well I already did not accept the free trial and paid the fee for shipping...maybe next time.
[02:26:31] <Wolf_> just need to watch the marketplace vs fulfilled by amazon
[02:34:00] -!- skunksleep has quit [Ping timeout: 244 seconds]
[02:34:51] <Wolf_> sometimes amazon also marks stuff down to clear stock
http://amzn.com/B000TIRZLK and I got
http://amzn.com/B006M706CW x2 for $6.60 each
[02:35:40] <PetefromTn_> heh WTF is that thing?
[02:36:14] <Wolf_> handless dead blow knocker
[02:36:25] <Wolf_> handleless*
[02:37:05] <PetefromTn_> I think I would wind up smashing the crap out of a finger with that thing hehe
[02:37:25] <Wolf_> its pretty handy for seating stuff in the mill vice
[02:37:35] <Wolf_> and putting ikea stuff together :D
[02:38:05] <PetefromTn_> I have a nice mallet with two different heads for that but I actually need another hammer for work

[02:39:50] <PetefromTn_> I swear I must live in a freaking metal working black hole around here. There is almost NEVER a craigslist ad selling real metalworking equipment or machinery nearby me...
[02:40:27] <jdh> cali, kansas, penn. all seem good for equipment
[02:41:07] <PetefromTn_> yeah it seems like California is a used metalworking equipment nirvana sometimes...
[02:41:43] <Wolf_> this area is kinda slim for anything priced decent
[02:43:15] <Wolf_> I’m still wondering why that van norman ram type horizontal/vertical I found on craigslist for $500 hasn’t sold, its been on there for months now
[02:44:04] <PetefromTn_> probably because it is a BIG HEAVY HIGH HP machine that MOST people don't even know what the hell it is...?
[02:44:31] <Wolf_> I think the price is under scrap lol
[02:44:46] <PetefromTn_> even a small one of those older horiz/vert machines is very very heavy let alone a big one.
[02:45:51] <Wolf_> Listing: vertical/ horizontal ram by Van Norman non-op currently, needs some reassembly no tooling, Very heavy, 1940's era. bring cash and a rollback to take it. $500 firm
[02:48:32] <Wolf_> I sent them a message, I’ll find out how bad it is tomorrow afternoon lol

[02:58:42] <Contract_Pilot> hahahah walmart another 20 motors. Order cancled in 4 hours... Technical Price Error! hahaha! I think they caught on!
[02:59:20] <Contract_Pilot> Next time i see them will just buy a couple using wifes account.
[02:59:27] <Wolf_> lol
[02:59:28] <Contract_Pilot> See if they full fill them
[02:59:45] <bobo__> Pete how close is York,Pa from where you are ?
[03:00:57] <Wolf_> least I have them 470w nema34 servos, should work good for something big :D
[03:01:02] <bobo__> seems like Pa should have used machinery
[03:01:11] <Wolf_> york, pa is close for me, somewhat
[03:04:33] <PetefromTn_> pretty danb far
[03:06:54] <bobo__> Wolf that Van-Norman mill , you might want to check what collets are available for it. I think the are not a common type.
[03:07:35] <Wolf_> yeah, will have to see what the spindle is on it

[03:13:39] <ssi> Wolf_: I'm putting a stmbl together
[03:13:46] <Wolf_> cool :)
[03:13:50] <ssi> there's a bunch of parts on the pcb that weren't on the bom :/
[03:14:25] <ssi> wait maybe not
[03:19:45] <Wolf_> wonder what the cost would be to have a spindle taper reground or w/ever needs to be done to change it over
[03:21:40] <bobo__> Wolf may not be enough material/space in the spindle to change it
[03:22:22] <Wolf_> I’ll keep that in mind and take some calipers with me too then when I go look at it
[03:22:43] <Wolf_> http://jmkasunich.com/vannorman/VN_Spindle.htm
[03:23:16] <bobo__> also look at spindle speeds
[03:28:06] <Wolf_> I’ll be taking a load of pics and getting as much info off the machine before I decide to get it
[03:28:54] <bobo__> Or it gets you.
[03:29:24] <Wolf_> yup lol
[03:29:46] -!- skunksleep has quit [Ping timeout: 240 seconds]
[03:31:42] <bobo__> pis and mone if the overarm outboard spindle support is missing. I bet it is missing
[03:33:42] <bobo__> horz spindle overarm support bearing thing-e
[03:34:38] <Wolf_> I have no idea what that is lol
[03:35:02] <Wolf_> oh wait,
http://www.practicalmachinist.com/vb/attachments/f19/35906d1309269494-van-norman-milling-machine-4810.jpg
[03:36:58] <bobo__> it supports the horz shaft at the outboard/far end ,for horz milling
[03:37:50] <Wolf_> yeah, its kinda obvious in that last pic I linked, but not knowing what model it is doesn’t help much (pic from goggle)
[03:42:16] <bobo__> always thought outside horz spindle supports for various older machines would be marketable items
[03:42:24] <Wolf_> its almost a hour drive to where that machine is so I’m going to go check it out in person first
[03:43:15] <Wolf_> will also help to see where it is how big it is so I can figure out which truck to take
[03:46:12] <bobo__> cast iron is heavy, and Van-Norman mills are not noted as being light weight
[03:47:05] <Wolf_> well I can take the f550 (can take 5tons) or the roll back
[03:49:47] <bobo__> to me most machines of that era were designed to maintain stated performace when sitting on a crappy wood floor
[03:50:58] <Wolf_> heh
[03:53:52] <bobo__> Hope it has a 40 or 50 taper spindle
[03:54:15] <Wolf_> yeah

[04:32:39] <Praesmeodymium> I was joking you have far too many for selling to you to make sense
[04:32:55] <Contract_Pilot> hahaha
[04:33:30] <Contract_Pilot> Chatting with the seller we were lucky to get the price we did.
[04:33:44] <Praesmeodymium> oh I am sure
[04:33:53] <Contract_Pilot> Said the price we got was an error/.
[04:33:58] <Wolf_> lol, I asked about tracking number for newegg order, reply in email “As such , we will issue a full refund for your purchase.” wtf lol
[04:33:58] <Praesmeodymium> I was hoping it was a typo or fire sale
[04:34:21] <Contract_Pilot> Typo.
[04:34:53] <Praesmeodymium> yeah I may not be getting my last 5 motors we will see no reply from the seller yet about my motors being delivered to georgia
[04:35:05] <Contract_Pilot> I hit buy on another 20 this morning this afternoon order cancled.
[04:35:19] <Wolf_> whats funny, that was the order that showed up today...
[04:35:47] <Praesmeodymium> LS152570014CN
[04:35:51] <Contract_Pilot> So they refunded you?
[04:36:03] <Praesmeodymium> that was the order I was waiting for
[04:36:14] <Contract_Pilot> the 3 PSU's not in the photo that the fans had issues were refunded.
[04:36:19] <Wolf_> I asked about LS152569395CN and they replied that they are refunding lol
[04:36:48] <Contract_Pilot> But arrived EMS Express humm..
[04:36:56] <Wolf_> except that I received the motors for that order in 2 usa shipped 2day packs
[04:38:51] <wolfmanjm> so the nema24 + controller were a typo? that explains why they are now $110

[04:39:52] <wolfmanjm> well I still need one more :)
[04:40:04] <Contract_Pilot> Look's like it will cost me 3.00 to fix them 3 PSU's
[04:40:19] <Contract_Pilot> What motor Size?
[04:40:34] <wolfmanjm> but I found some interesting ones relatively cheap triple stack nema17 which may have enough torque for what I want
[04:41:01] <wolfmanjm> me?
[04:41:23] <wolfmanjm> the nema24 or nema23 would work for me
[04:41:55] <wolfmanjm> I'd like another of the 300oz.in if possible but I suspect that is more torque than I need for the third one
[04:42:32] <Praesmeodymium> whats it take to fix em? I also have the saem 12v fan
[04:43:20] <Contract_Pilot> Y2 so23 transistor.

[06:17:51] <Connor> Contract_Pilot: How much did you end up paying for all those steppers and drivers?
[06:17:54] <Praesmeodymium> I got some nice 12v5v 24w ones for small electronics projects at 3$ thats plenty for a duino and a couple motors
[06:18:10] <Connor> and what's the model # on the drivers?
[06:18:50] <Praesmeodymium> the drivers we got ar mb450a
[06:20:14] <Contract_Pilot> till you look inside and they are M542 V2.0 somthing like that.

[09:53:21] <XXCoder> just really clean out the bearings
[09:53:39] <gonzo__> also they had far less friction than the acme ones. So kinder on the motors
[09:54:46] <gonzo__> (though still not used the axis in anger, will be interesting to see how they go)
[09:55:07] <XXCoder> cool
[09:55:22] <XXCoder> been so busy hardly ever worked on my cnc router lol
[09:56:42] <Praesmeodymium> well im so poor I have nothing but time to imagine working on a cnc router
[09:56:57] <XXCoder> you can scrap stuff to build one
[09:57:00] <XXCoder> for example
[09:57:14] <XXCoder> go to old hardware stuff, find a big laser printer
[09:57:14] <Praesmeodymium> yeah theres routers and theres routers
[09:57:20] <XXCoder> it usually has few steppers
[09:58:17] <Praesmeodymium> I have motors, I buuld 3d printers I just want to be able to cut aluminum with a decent amount of precision and it not take all day to do an angle bracket
[09:58:40] <XXCoder> ahh yea
[09:58:40] <Praesmeodymium> can I scrap a decent spindle fromsomething?
[09:58:55] <XXCoder> well you can always use wood router
[09:59:03] <XXCoder> it can cut alum, if bit slowly
[10:00:12] <XXCoder> theres plenty on aliexpress but of course not free

[10:06:00] <XXCoder> fadal is selling mills again
[10:06:16] <XXCoder> and its interface is mostly like their orginial fadal 88

[12:07:43] <fenn> jthornton: could you name it something different? there are already several programs named dxf2gcode
[12:08:35] <jthornton> you mean there are more dxf2gcode.go programs out there?
[12:08:39] <fenn> no
[12:08:43] <jthornton> why is the name important?
[12:09:00] <fenn> because it's confusing for people who don't realize that there are multiple different programs with the exact same name
[12:12:35] <jthornton> ok no confusion now

[12:15:40] <Tom_itx> good luck there
[12:15:48] <jthornton> are you saying hypothetically someone might get confused?
[12:16:07] <archivist> using someone else's name for a program is not helpful
[12:16:21] <fenn> this seems like the appropriate time to bring it up, since the software hasn't been around long enough to have any links or references pointing to it yet
[12:16:24] <archivist> especially is it performs the same function
[12:16:34] <Tom_itx> they are 2 separate file formats just rolled into a name
[12:16:38] <Tom_itx> how confusing is that?
[12:17:21] <fenn> tom the problem is the already existing program dxf2gcode

[17:02:03] <Jymmm> enleth: you design, as in select and use various north/south chips, etc?
[17:02:35] <Jymmm> enleth: or you bbuild up boxes?
[17:03:09] <enleth> No, as in technical design of systems that do credit card transaction processing. Hardware selection, software engineering, network design.
[17:04:01] <Jymmm> to be, that's just SysAdmin stuff. par for the course.

[18:12:11] <renesis> geometric dimensioning and tolerancing
[18:12:42] <renesis> https://www.deanza.edu/cdi/images/GDT2.JPG
[18:12:48] <renesis> all the shit in the boxes, basically
[18:15:15] <_methods> yeah you actually make stuff out on the floor so you have to know how it works lol

[18:16:58] <MacGalempsy> looks like a good thing to learn
[18:21:24] <renesis> besides allowing more controls to suggest design intent (can be challenging) it can kill ambiguity in inspection (really easy to impliment)
[18:22:36] <_methods> or if done incorrectly cause tons of ambiguity
[18:22:38] <renesis> specifying datum features without controls tells inspection dude 'locate it like this, and then this, and then this' so two people cant get diff measurements just by how they decided to lay the part onto the inspection plate
[18:23:05] <renesis> _methods: sure but thats true of cartesian coordinate dimensioning too, shrug
[18:23:11] <_methods> yeah
[18:23:56] <_methods> it's hard to get teh old bastards on board with it
[18:24:13] <renesis> even when its not ambiguous, calculating dimension zones for stacked controls that its likely they wont be used as intended

[18:25:03] <renesis> FUCK THIS MATH JUST THROW THE PART AWAY AND DO IT AGAIN
[18:25:20] <_methods> maximum material what
[18:25:23] <_methods> lol
[18:25:35] <_methods> why can't they just say +/-.01
[18:25:49] <renesis> yeah when you tell them shit like, the tolerance zones turns into a slightly lima beaned oval, theyre like FUCK YOU MAN WHAT
[18:27:02] <renesis> and im not sure there are any conditions where you can MMC without a limit tolerance
[18:27:56] <_methods> they always get very angry when i start trying to explain profile
[18:28:16] <Tom_itx> maybe they don't understand
[18:28:40] <_methods> i think most people just don't like change
[18:28:49] <Tom_itx> true

[18:29:17] <Tom_itx> change keeps you on your toes
[18:29:22] <_methods> tru dat
[18:30:31] <_methods> i mean 2 words
[18:30:34] <_methods> metric system
[18:30:51] <_methods> can barely get guys to tolerate that
[18:30:59] <_methods> now you throw GD&T at them
[18:31:06] <_methods> black magic
[18:31:37] <renesis> have you explained that GD&T implies metric unless specified otherwise?
[18:31:59] <_methods> renesis: i can only handle 1 test at a time lol
[18:32:00] <renesis> i kind of think that was a dick move on ASME's part
[18:33:17] <renesis> i think itll get better when its integrated into cad better, right now solidworks GD&T is basically a stamp you can abitrarily format
[18:33:41] <renesis> you can prob set MYNUTS as a datum feature
[18:33:56] <andypugh> It has occasionally amused me to give a 100mm+/-10 dimension
[18:34:23] <renesis> have confirmed, can set datum in feature control frame to MY NUTS when MYNUTS datum hasnt been defined on the drawing
[18:34:44] <_methods> you can change whatever you want
[18:34:50] <_methods> you can change the dimension too
[18:34:53] <_methods> it will break the link
[18:34:56] <_methods> but you can do it
[18:35:01] <renesis> but if it was an active feature that calculated tolerance zones and visualized them, i think people would be down with GD&T
[18:35:15] <_methods> it will come around
[18:35:17] <_methods> just takes time
[18:35:22] <_methods> old people have to die
[18:35:23] <renesis> i wonder if thats even been started as a solidworks feature and then abandoned because engineers suicided
[18:36:00] <_methods> once again i reference us's aversion to metric system adoption
[18:36:06] <_methods> it might take about 200 years
[18:36:14] <_methods> but sooner or later we'll do it lol
[18:36:14] <tiwork> oh you guys talking about metric?
[18:36:22] <_methods> no GD&T
[18:36:24] <_methods> adoption
[18:36:30] <renesis> tiwork: GD&T is metric, per the spec

[18:37:10] <renesis> i like inches
[18:37:19] <renesis> inches are base 1000, like most engineering things
[18:37:31] <tiwork> not that I mind the metric system, I just refuse to machine parts using metric
[18:37:34] <renesis> wtf is a decimeter?
[18:37:42] <tiwork> I've designed plenty of things with the metric system
[18:37:42] <renesis> who knows but some fucks gonna use it
[18:37:50] <andypugh> There is no place for the decimeter in SI
[18:38:01] <renesis> also using base 100 and base 1000 often is a great way to fuck shit over
[18:38:05] <andypugh> SI is mm, m, km
[18:38:25] <renesis> yesh cm is used a ton
[18:38:32] <pcw_home> Base 10 is plain stupid dump this metric crap
[18:38:34] <andypugh> Not by engineers.

[18:39:48] <renesis> but seriously wtf is 10^-5 Farads
[18:40:00] <_methods> ask pete
[18:40:08] <_methods> he was using some cleaner for his anodizing
[18:40:12] <tiwork> who isnt here at the moment XD
[18:40:12] <_methods> or CaptHindsight
[18:40:21] <tiwork> oh yeah CaptHindsight
[18:40:26] <_methods> i think he sold pete some stuff
[18:40:44] <tiwork> depending on when I order stuff, I might try anodizing things next week
[18:40:51] <renesis> petes Al anodizing came out so sexy
[18:40:57] <tiwork> yeah I know
[18:40:58] <andypugh> renesis: I don’t understand. What would be the “Imperial” form of 10^-5 Farads?
[18:41:02] <tiwork> I saw pictures!
[18:41:16] <renesis> andypugh: 10 uF
[18:41:26] <_methods> it's a trap don't answer his question
[18:41:27] <andypugh> That’s SI / metric
[18:41:30] <renesis> and thats not an imperial thing
[18:41:37] <_methods> hahahah
[18:41:41] <renesis> thats a practical engineering versus theoretical physicist thing
[18:41:50] <tiwork> andypugh: what is the imperial version of the minute?
[18:42:11] <tiwork> :P
[18:42:13] <renesis> 60*s yo
[18:42:14] <andypugh> I am actually wondering what the Imperial Farad would be
[18:42:52] <andypugh> Presumably there is a way to convert e to inch/lb units.
[18:42:55] <renesis> there are no days, only 8.64*10^4s
[18:43:17] <tiwork> there are lots of different units of measure for various different applications... sheesh.. like grains and ponies
[18:43:44] <renesis> is ponis what they use for naval cannon shells?
[18:43:48] <tiwork> no
[18:43:54] <tiwork> its a "shot"
[18:43:58] <renesis> damn because thats an awesome visual
[18:44:10] <_methods> poni power
[18:44:24] <renesis> hey you guys know about pono player?
[18:44:27] <renesis> piece of shit
[18:44:29] <tiwork> pony up... I suspect came from taking a shot of alcohol
[18:44:43] <renesis> niel young is officially an audiophoolish fuck
[18:44:46] <tiwork> and pony is a shot of alcohol
[18:45:32] <andypugh> “The farad is the standard unit of capacitance. Reduced to base SI units one farad is the equivalent of one second to the fourth power ampere squared per kilogram per meter squared (s4 A2/kg m2).” So you ought to be measuring your Imperial Capacitances in second4.Amp.lb/ft2
[18:46:54] <tiwork> lol
[18:47:02] <tiwork> that... is some weird units
[18:48:02] <tiwork> so CaptHindsight sold pete some anodizing stuffs?
[18:48:50] <CaptHindsight> we make inks for anodizing for inkjet, spray, sillscreen etc
[18:49:48] <tiwork> CaptHindsight: water based?
[18:52:01] <tiwork> CaptHindsight: cause at the moment, I'm looking at caswell for sourcing some (most? all?) of this stuff
[18:53:03] <CaptHindsight> tiwork: solvent
[18:53:56] <CaptHindsight> if you are still learning then order the casewell stuff
[18:54:42] <tiwork> heh
[18:56:20] <tiwork> what kind of color options do you have? is the dye that much better? I already have some dye from caswell, was going to (more or less) start with that, but for some of the other stuff I need different colors

[19:05:57] <tiwork> http://www.caswellplating.com/anodizing-products/anodizing-accessories/aluminum-deoxidizer-desmut-1-quart.html
[19:06:06] <OhmEye> I'm using the default livecd install of 2.7
[19:07:25] <andypugh> But which User Interface? I guess it is probably Axis, as Touchy already has a commanded speed indicator
[19:07:32] <OhmEye> yes, axis
[19:08:07] <OhmEye> there are 3 little buttons under the manual axis controls for spindle - Stop +
[19:08:24] <OhmEye> er, little circular arrow buttons too.
[19:08:39] <CaptHindsight> tiwork: just get the kit, our stuff is for industrial and lab use
[19:09:04] <OhmEye> it controls fine, it's just actually less convenient than using the manual knob on the control box if it doesn't display current value
[19:09:57] <OhmEye> I will look at Touchy, wasn't aware of it until you mentioned it
[19:10:11] <andypugh> OhmEye: One way, add this to your HAL file “loadusr halmeter -s pin motion.spindle-speed-out”
[19:10:40] <OhmEye> andypugh: thanks, I'll check that out :)
[19:10:56] <andypugh> For more advanced ways integrated into the UI:
http://www.linuxcnc.org/docs/html/gui/pyvcp-examples.html
[19:11:30] <tiwork> CaptHindsight: I ask cause one of my customers was asking about hard anodizing as well... I don't have the drawing yet, but its something I will probably end up at least trying.
[19:11:46] <andypugh> OhmEye: You can just open a terminal and type “halcmd loadusr halmeter -s pin motion.spindle-speed-out” if you want to see what the effect is without restarting Axis

[22:15:54] <andypugh> JT-Shop: Use a swarm of drones
[22:16:05] <Tom_itx> it would be
[22:16:12] <JT-Shop> I'm out, can you email me some?
[22:17:27] <andypugh> Somone on here bought a dozen at $2 each, IIRC

[22:22:10] <andypugh> I have decided I do want a Lily Camera drone. But getting one probably just needs a butterfly net this ski-season. :-)
[22:23:11] <JT-Shop> well the ammo tins got me two more rows now to elevate to saw horses

[22:26:53] <JT-Shop> crap it's supposed to rain all weekend
[22:27:12] <JT-Shop> maybe I can figure out how to sort the entities
[22:28:51] <andypugh> JT-Shop: Abseil out of a window?
[22:29:21] <Sync> I like how it is abseil
[22:29:25] <SpeedEvil> andypugh: Me.
[22:29:35] <SpeedEvil> andypugh: They seem to have shipped me ten.
[22:29:49] <SpeedEvil> Thoguh not the 26 that I ordered 4 minutes later
[22:29:58] <andypugh> Are they big enough to lift JTs siding?
[22:30:10] <SpeedEvil> andypugh: Is he into dollshouses?
[22:30:19] <Sync> andypugh: you want one of those scam drones?!
[22:30:26] <andypugh> I am unaware of his other hobbies
[22:30:46] <SpeedEvil> (I would suspect the payload would be around 5 grams - hence it would only be useful for very small scales of siding.
[22:31:14] <andypugh> Sync: I want the Lily as-advertised. What the production model will be like I don’t know. But what makes you so sure that it is a scam?
[22:33:12] <Sync> because it cannot do what it claims
[22:33:38] <andypugh> Why not?
[22:34:48] <andypugh> (YOu would need to ski/whatever like you had a balloon on a string, as there is no collision avoidance)
[22:35:38] <Sync> people have gotten prototypes and it is neither launchable by throwing, the tracking does not work (unlikely for any system in the near future) and the battery lifetime is pathetic
[22:35:47] <Sync> same with zano, it is a plain scam
[22:36:42] <andypugh> Prototypes don’t normally work, otherwise they would be production units…
[22:36:53] <SpeedEvil> andypugh: unless it's kickstarter
[22:37:37] <andypugh> My Kickstarter experience has been largely positive. Though my oscilloscope watch is 2 years late.
[22:37:41] <Praesmeodymium> I think protypes come in flavors, proof of concept, mock up, and working
[22:37:48] <JT-Shop> maybe it is variable scope that is messing me up
[22:37:54] <Praesmeodymium> prolly a few subtleties too I am missing
[22:38:08] <Sync> well, I do expect prototypes to do remotely that what they are supposed to do
[22:38:14] <Sync> otherwise they are not prototypes
[22:38:22] <Sync> and being a drone is not a prototype
[22:38:25] <Sync> you can buy that off the shelf
[22:46:13] <andypugh> I could so with a board-o-holes for my ER collets, I have 4 different sizes of the things (32, 20, 16, 11)
[22:46:43] <Tom_itx> did you stagger them to conserve space?
[22:47:37] <andypugh> I haven’t made any sort of layout yet, but I wonder if nesting them with little ones between big ones helps.
[22:47:55] <Tom_itx> probably just be confusing
[22:48:24] <malcom2073_> I need to do a board of holes for my endmill holders, is it lame to do it out of wood?
[22:48:32] <JT-Shop> mine are in order by size makes it easier to find
[22:48:49] <JT-Shop> one box for each type of collet
[22:48:51] <Tom_itx> malcom2073_, make one from solid billet
[22:49:07] <Tom_itx> and anodize it
[22:49:09] <renesis> 22:37 < Praesmeodymium> I think protypes come in flavors, proof of concept, mock up, and working
[22:49:20] <renesis> thats how it works in consumer electronics manufacturing
[22:49:34] <malcom2073_> hah
[22:49:34] <Tom_itx> we had boards of holes all over the shop
[22:49:40] <malcom2073_> With the number of holders I have, that owuldn't be cheap
[22:49:55] <renesis> 22:36 < andypugh> Prototypes don’t normally work, otherwise they would be production units…
[22:50:04] <renesis> we call those production prototypes
[22:50:21] <renesis> in an ideal world, you should be able to sell production prototypes, but usually it takes a few tries
[22:50:45] <renesis> often initial production prototypes are what the engineers and techs get to take home
[22:53:03] <renesis> and i guess literally speaking, in terms of prototype meaning 'single and only unit', its the the builds at various stages of development and manufacturing that are prototypes, not the units themselves
[22:56:15] <zeeshan> archivist: those are pretty big :P

[23:04:46] <andypugh> My toolholder holder is wood.

[23:06:30] <malcom2073_> Nice, I like the tiered approach
[23:08:41] <andypugh> I think it is stronger that way, though I could be persuaded otherwise.
[23:09:43] <DaViruz> i produced a prototype at work this week that worked fine. then a collegue of mine proceeded to make 15 more, i guess production units, which didn't work at all
[23:09:57] amnesic_away is now known as amnesic
[23:10:26] <andypugh> I once made a circuit that worked well on solderless breadboard, but not when made as a PCB.
[23:10:52] <DaViruz> stray capacitance?
[23:10:58] <andypugh> I guess the track-to-track capacitance helped or something.
[23:11:18] <andypugh> It was an LCLC Wheatstong bridge
[23:11:25] <andypugh> (Wheatstone)
[23:11:48] <renesis> what were the caps?
[23:12:06] <andypugh> One was two aluminium tubes sliding coaxially.
[23:12:17] <andypugh> Not big capacitancees
[23:12:47] <renesis> oh, yeah shit was prob dozens of pF, solderless breadboard could totally mess with that
[23:12:50] <andypugh> It was a non-contacting very high speed displacement transducer.
[23:13:13] <renesis> was it in a box or something?
[23:13:35] <renesis> fly could land on that and it probably changes the capacitance, heh
[23:13:39] <andypugh> The breadboard wasn’t
[23:13:52] <renesis> i mean the tube sensor
[23:14:12] <andypugh> I was a bit stuck for another way to measure 100mm displacement at 50mph....
[23:14:24] <renesis> nice
[23:14:25] <andypugh> Oh, for zero budget.
[23:14:34] <renesis> optical interrupt!
[23:14:50] <andypugh> I needed analogue position
[23:15:09] <andypugh> I probably wouldn’t do it the same way again, this was 25 years ago.
[23:15:13] <renesis> hall sensor, bigass magnet
[23:15:22] <renesis> but yeah thats not gonna be cheap
[23:15:38] <renesis> def not cheap that long ago

[23:16:41] <Praesmeodymium> tof is still pretty long range aint it?
[23:17:18] <Praesmeodymium> I mean the response time for something cnc sized is epically fast and therefore spendy last I looked
