[02:29:21] <Jak_o_Shadows> Happy new year rue
[02:42:37] * ace4016 throws confetti at rue
[03:14:29] <rue_house> ;)
[03:14:51] * rue_house snaps a cd over ace4016
[03:15:05] <rue_house> weee all the glitter!
[04:31:33] <Jak_o_Shadows> You have broken many CD's recently havent you
[05:05:15] <rue_shop3> the ones I was cutting just kinda bend
[05:25:50] <rue_shop3> wow, even when made on the lathe, a shaft-to-threaded-rod coupler NEVER lines up
[05:27:16] <rue_shop3> that said, its impossable to hard couple a threaded rod using ANYTHING and have it line up
[05:28:11] <rue_shop3> well that was a waste of 3 hours
[05:29:23] <robopal> what's up? what are you making?
[05:29:37] <rue_shop3> I'm tryting to couple a motor to a threaded rod
[05:29:52] <rue_shop3> I just spent 3 hours on the lathe making a straight shaft to threaded coupler
[05:30:12] <rue_shop3> like everything else I'v ever made in the last 20 years, it didn't line up right
[05:30:44] <rue_shop3> if it were possable, I'd have been able to do it once in 20 years
[05:31:04] <robopal> can you braze? :D
[05:31:08] <ferdna> what do you call that tool to put your pcb board in... it is a perforated table and you can adjust the dowels to fit your pcb
[05:32:53] <ferdna> found it
[05:32:56] <robopal> I had to replace a toy motor yesterday, it was bizarre, it stuck somehow and it was difficult to rotate, I couldn't see the problem :-/
[05:32:56] <ferdna> "PCB Tooling Block"
[05:35:25] <rue_shop3> you know, I'd bet if you took two peices of threaded rod and put them into a coupling but they wouldn't line up either
[05:37:04] <robopal> yeah maybe
[06:10:45] <rue_shop3> gonna try 3d printing a spring coupler
[06:16:03] <deshipu> try an autumn coupler
[06:20:54] <rue_shop3> I do not want to add a month to this project by ordering anything
[06:21:00] <rue_shop3> and it will if I do
[06:26:53] <deshipu> at least 4 months, between spring and fall
[06:46:05] <rue_shop3> oh yea DO NOT buy from china during chinese newyear
[06:48:03] <rue_shop3> damnit, maybe i'll just belt drive all of these
[07:24:24] <rue_shop3> Tom_L, can I run a gearbelt at 10k rpm or will it just melt
[07:46:59] <malcom2073> rue_shop3: You can't use a solid coupler. It is impossible to align three bearings perfectly.
[07:47:21] <malcom2073> Much less four, two on a motor + two on a shaft
[07:55:40] <rue_bed> yea, I prettymuch sold myself on using a gearbelt
[10:00:27] <doomlord> anyone around ?
[10:02:24] <deshipu> no, go away
[10:43:17] <z64555> malcom2073: solid coupler? what if the bearings were roller type?
[14:18:44] <devcodev> hello I want to build an app using photogrammetry will use opencv can anyone suggest books / resources
[14:37:05] <devcodev> also any pointers on the related math required
[14:39:48] <rue_bed> openAR
[14:40:08] <rue_bed> have it locate a glyph in 3d space
[14:41:12] <rue_bed> wait a sec, pwm dosn't generate interrupts
[14:41:25] <rue_bed> oh the adc would, but I dont have to use it like that
[14:41:30] <rue_bed> ooh
[14:41:38] <rue_bed> maybe a tiny13 is ok
[14:46:46] <Tom_L> been fighting a bad hdd cable for weeks.. finally think i pinpointed the issue
[14:47:01] <rue_bed> hate that
[14:47:14] <rue_bed> <rue_shop3> Tom_L, can I run a gearbelt at 10k rpm or will it just melt
[14:47:18] <Tom_L> i hope anyway
[14:47:26] <Tom_L> i dunno
[14:47:32] <Tom_L> they seem to do pretty well
[14:47:40] <rue_bed> k, you can do 10k?
[14:47:45] <Tom_L> i'd use the rounded tooth ones instead of the square
[14:47:49] <Tom_L> i can't
[14:47:57] <Tom_L> mine only does ~5500 rpm
[14:48:08] <rue_bed> I thought you brought that up
[14:48:16] <Tom_L> i'd cook the bearings in the spindle i bet
[14:48:43] <Tom_L> after the sprocket changes it will do 5500 instead of around 2800-3k
[14:48:54] <Tom_L> stock is around 3k iirc
[14:49:12] <Tom_L> acording to lcnc and my encoder on it
[15:02:33] <Tom_L> rue_bed GT3 belt: do not exceed 6500 fpm with stock sprockets
[15:02:46] <Tom_L> dunno what that translates into rpm
[15:03:43] <ASRock_pc> https://www.gates.com/~/media/files/gates/industrial/power-transmission/manuals/powergripdrivedesignmanual_17195_2014.pdf?la=en
[15:04:36] <ASRock_pc> P.4
[15:05:38] <Tom_L> the chart on P7 shows 10k for GT3 series though
[15:05:50] <Tom_L> 5mm wide
[15:09:29] <Tom_L> P12 has speed ratio for sprocket sizes
[15:09:43] <Tom_L> and center distance for belts
[15:12:20] <Tom_L> i had to bore one of mine and make a bushing for one on the encoder pullies
[16:35:30] <rue_shop3> cooool!
[16:50:49] <z64555> warm?
[16:55:36] <rue_shop3> gives me an idea what I'm looking for
[17:35:35] <z64555> warmer!
[18:00:58] <rue_shop3> ok, have the spindle bearing assembled for the cnc, just running it in on the drillpress at 2100
[18:03:44] <Tom_L> far cry from 10k
[18:08:51] <rue_shop3> its just a wear in
[18:09:08] <rue_shop3> just bumped it up to the 4200 the drillpress can do
[18:09:25] <rue_shop3> but It seems the 608 bearings are heating up a bunch
[18:09:33] <rue_shop3> I wonder of 608's cant take 10k
[18:09:38] <Tom_L> no
[18:09:56] <rue_shop3> why not
[18:10:17] <rue_shop3> :)
[18:10:42] <Tom_L> deep grove cheap chinese 608's i'm sure
[18:11:38] <rue_shop3> er 3100 is the drillpress max
[18:11:54] <rue_shop3> the shaft in the bearings is getting quite warm
[18:12:19] <Tom_L> put a pulley in it and hold the spindle with a pulley/belt
[18:12:40] <Tom_L> 3:1 will get you close to where you wanna be
[18:12:49] <rue_shop3> I have a 10k motor for the cnc
[18:12:54] <rue_shop3> cordless drill
[18:12:57] <Anniepoo__> or put a wheel in the chuck and drive the spindle by friction
[18:13:10] <rue_shop3> I'm just working it in at 3100
[18:13:26] <rue_shop3> give it a 30min breakin or somehting
[18:13:29] <Anniepoo__> 8c/ sounds like you have cheap bearings
[18:13:38] <rue_shop3> duh..
[18:13:46] <rue_shop3> why would I get good ones?
[18:13:57] <rue_shop3> ceramic bearings?
[18:14:00] <Anniepoo__> so they don't heat up?
[18:14:17] <rue_shop3> its prolly a shaft/bearing misalignment
[18:14:27] <Anniepoo__> I don't know enough about ceramic bearings to answer that
[18:14:43] <rue_shop3> the holder is a 1/2" iron T fitting thats been borred out
[18:15:04] <Anniepoo__> is that how you solved the coupler issue?
[18:15:32] <Anniepoo__> I wonder if that's inducing vibration
[18:15:41] <rue_shop3> http://ruemohr.org/~ircjunk/projects/cnc3/p1070979.jpg
[18:15:55] <rue_shop3> see the spindle holder on that? I made another one
[18:16:06] <Anniepoo__> ah
[18:16:18] <Anniepoo__> that's a cool design
[18:16:21] <rue_shop3> no, the couplers, i'm not doing and I found some synchrobelt sets that will work
[18:16:32] <rue_shop3> that machine isn't working out, prolly gonna be abandoned
[18:16:37] <rue_shop3> I started another one
[18:17:02] <Anniepoo__> 8cD that's often a good course
[18:17:07] <rue_shop3> the siders are all the wrong way around on that one
[18:31:30] <rue_shop3> ah, it was spinning the bearing
[18:32:12] <Tom_L> not supposed to do that
[18:37:17] <rue_shop3> the shaft is a hair small for the bearing
[18:37:29] <rue_shop3> the id tolerance of the 608 bearings is horrid
[18:54:21] <z64555> drop of oil or grease should do
[19:08:44] <Anniepoo__> rue, thanks for reporting all this
[19:08:47] <Anniepoo__> I'm learning
[19:10:11] <rue_shop3> :)
[19:11:36] <Tom_L> rue how can you merge 2 files with differences from both?
[19:13:38] <rue_shop3> anniepoo, bottom line, just build things, you cant avoid every problem that will exist and you cant know what problems matter without experience
[19:13:45] <rue_shop3> Tom_L, ouch
[19:13:51] <rue_shop3> not good with diff
[19:13:56] <rue_shop3> text?
[19:14:05] <Tom_L> yeah it's ok though i think i've got it
[19:15:26] <rue_shop3> :) the "4mm" bearing balls i got from china nonally aren't 4mm, they aren't all the same
[19:18:41] * rue_shop3 just remembered the existance of self-centering bearings
[19:26:46] <Anniepoo__> rue, I build stuff every day.
[19:27:53] <Anniepoo__> 8cD I don't really have a choice
[20:31:03] <ferdna> has anyone fix a vacuum pump before?
[20:31:07] <ferdna> i cant get mine to work
[20:31:19] <Anniepoo__> what kind of pump?
[20:31:31] <ferdna> 12v vacuum pump
[20:31:41] <Anniepoo__> diaphragm?
[20:32:21] <z64555> https://en.wikipedia.org/wiki/Vacuum_pump
[20:32:23] <ferdna> no
[20:32:42] <Anniepoo__> lobular pump?
[20:33:19] <Anniepoo__> do you have a picture, pref with the case open?
[20:33:22] <ferdna> Anniepoo__, lol... i really dont know... but it uses electromagnecs to spin a shaft... that shaft
[20:33:24] <ferdna> http://i.ebayimg.com/00/s/NDA1WDcyMA==/z/GGEAAOSwNSxVZnQ5/$_58.JPG
[20:33:35] <Anniepoo__> ok
[20:33:48] <Anniepoo__> that helps
[20:34:06] <Anniepoo__> this is probably a positive displacement pump - diaphragm or piston
[20:34:55] <ferdna> this is the one i bought
[20:34:56] <ferdna> http://www.ebay.com/itm/Thomas-014CDC20-12-E-Compressor-Vacuum-Pump-/112227301722
[20:34:59] <ferdna> but!
[20:35:03] <ferdna> that is not the one i got
[20:35:38] <Anniepoo__> so, it looks like this is a small piston pump
[20:36:11] <ferdna> yeah
[20:36:12] <Anniepoo__> a) can you blow air from the out side and have it come out the in side?
[20:36:25] <ferdna> Anniepoo__, i dissasemble it.
[20:36:33] <ferdna> so i have the motor apart from the "pump" part
[20:36:37] <ferdna> the motor doesnt spin
[20:36:40] <ferdna> at all
[20:36:52] <z64555> burnt out, perhaps
[20:36:57] <Anniepoo__> then the motor's bad 8cD
[20:37:03] <z64555> Can you spin the pump by hand?
[20:37:08] <z64555> (or with a tool)
[20:37:11] <ferdna> yes i can spin by hand
[20:37:14] * Anniepoo__ is amazed at her own deductive ability
[20:37:19] <z64555> does it provide suction?
[20:37:25] <ferdna> no it doesnt spin
[20:37:48] <Anniepoo__> no, z means, if you spin the pump by hand, does it provide suction
[20:37:54] <ferdna> so i dissasemble the motor and it has two brushes... i measure voltage to those brushes and i do get 12volts
[20:38:06] <z64555> k, so, something might have jammed the pump and thus burned out the motor
[20:38:09] <ferdna> Anniepoo__, ohh no idea... i didnt try that
[20:38:16] <z64555> oh.
[20:38:30] <ferdna> z64555, can i fix the motor?
[20:38:51] <Anniepoo__> honestly, I doubt there's anything 'fixable' in this turkey.
[20:38:51] <z64555> probably not with your current level of electronics knowledge. :)
[20:39:10] <ferdna> really?? why!! i spent 30 dllrs on that... :(
[20:39:34] <Anniepoo__> 8c( ebay is what it is
[20:39:51] <ferdna> *uck :(
[20:39:54] <Anniepoo__> I mean, you can look for a replacement motor
[20:40:09] <z64555> Yeah, that's the easiest way to do it
[20:40:11] <z64555> but
[20:40:12] <Anniepoo__> and figure out why it's jammed
[20:40:15] <Anniepoo__> but...
[20:40:24] <z64555> Make sure the pump works first
[20:40:31] <Anniepoo__> what z said
[20:40:48] <ferdna> hmmm
[20:40:51] <Anniepoo__> and if the pump's dead, it's probably even less repairable
[20:41:00] <ferdna> i rather learn how to fix this motor
[20:41:08] <ferdna> if you guys can point to help full resources
[20:41:15] <z64555> at which point, you'd be better off buying a new pump, instead of just the motor
[20:41:47] <Anniepoo__> ferdna, to fix the motor probably means rewinding it
[20:42:12] <Anniepoo__> that's going to cost, at minimum, buying some tools and a roll of maget wire
[20:42:17] <ferdna> z64555, they are ~80 dllrs used... pulled from working equipment
[20:42:18] <ferdna> :(
[20:42:30] <ferdna> Anniepoo__, i see =(
[20:42:54] <z64555> well a $30 paperweight isn't much of an improvement. :)
[20:43:15] <ferdna> loook
[20:43:16] <ferdna> https://youtu.be/-pTDF6R9-RA?t=82
[20:43:22] <ferdna> see what his fingers are pointing at
[20:43:28] <ferdna> those are the small brushes i am talking about
[20:43:44] <ferdna> so i measure power to those things and i get 12v
[20:43:47] <z64555> no no. That's not the problem
[20:44:04] <z64555> the motor's burnt out, and is also frozen
[20:44:13] <ferdna> ohhh
[20:44:35] <z64555> Yeah, replacing the brushes might be a step in getting it back to work
[20:44:44] <z64555> but it most certainly is not the only step
[20:44:49] <Anniepoo__> the sequence of failure was - pump frozen, motor can't turn
[20:44:56] <Anniepoo__> when a motor can't turn, it burns out
[20:45:12] <ferdna> :(
[20:45:14] <ferdna> all right
[20:45:32] <z64555> yes. This means that the coils on the armature heat up to much, and often weld themselves together
[20:45:36] <Anniepoo__> usually somewhere in the fine wire winding, the winding melts
[20:45:48] <z64555> yes
[20:45:50] <Anniepoo__> or the brushes cath fire
[20:46:08] <z64555> both instances, you let out the "magic smoke"
[20:46:24] <z64555> (it's an electronics joke)
[20:47:26] <Anniepoo__> but it's really not possible to repar this without a motor shop. They'd charge you $250 to fix it... so you're better off just getting a pump from a more reputable source
[20:47:54] <ferdna> any recomendations?
[20:48:13] <Anniepoo__> what's the application?
[20:48:35] <Anniepoo__> and do you have a compressed air source?
[20:49:35] <ferdna> no i dont have a compressed air source
[20:49:38] <ferdna> do i need one?
[20:50:06] <ferdna> do those type of vacuum pumps need a compressed air source?
[20:50:11] <Anniepoo__> no
[20:50:32] <Anniepoo__> there's a very simple way to get vacuum if you already have compressed air
[20:50:42] <Anniepoo__> but you don't, so forget it
[20:50:56] <Anniepoo__> what's the application (second time).
[20:51:14] <ferdna> pick up tool
[20:51:26] <Anniepoo__> ok, so you don't need a ton of air flow
[20:51:32] <z64555> what's the heaviest you want to pick up?
[20:51:57] <ferdna> hmmm ... atmegas
[20:52:29] <Anniepoo__> you know, I was watching youtube video on smt soldering, the guy suggested getting a pick up tool, made the comment that they cost about $40

[20:54:51] <z64555> That pen one seems to be the El Cheapo special
[20:54:54] <ferdna> this is what i am doing:

[20:55:52] <z64555> You don't have to follow those verbatim, by the way
[20:56:30] <ferdna> nope
[20:58:53] <z64555> Here's one similar to yours:
https://www.amazon.com/Karlsson-Robotics-D2028-Vacuum-Pump/dp/B00DYA21PU/ref=sr_1_4?ie=UTF8&qid=1483324074&sr=8-4&keywords=vacuum+pump
[20:59:23] <ferdna> hey if i spinn it and it generates electricity does that means the windings are okay?
[20:59:29] <Anniepoo__> yes, it does
[21:00:06] <z64555> not necassarily
[21:00:10] <Anniepoo__> put power on it removed from the pump
[21:00:26] <Anniepoo__> (you still might have one open winding)
[21:00:30] <z64555> yes
[21:00:41] <Anniepoo__> see if it spins
[21:01:08] <z64555> It'll have reduced power and efficiency, but it might be enough to get things working
[21:01:54] <z64555> ok, I'mma stop backseat helping for awhile
[21:02:02] <Anniepoo__> apply power, and if it doens't move, spin the shaft to see if it's just stuck on a dead sector
[21:02:09] <ferdna> z64555, thanks so much!
[21:02:13] <Anniepoo__> actually z, why don't you do the helping, I'll shut up
[21:02:18] <Anniepoo__> you're being more help
[21:02:28] <z64555> I need to walk the dog, though. :(
[21:02:32] <Anniepoo__> kk
[21:02:40] <ferdna> Anniepoo__, so apply power and hand spin it? and look for what?
[21:02:48] <Anniepoo__> see if it runs
[21:02:58] <Anniepoo__> (with pump detached)
[21:03:15] <Anniepoo__> you did a) apply power and see if it pumps air
[21:03:21] <Anniepoo__> it didn't and the motor didn't turn
[21:03:38] <Anniepoo__> you disconnected the motor, and now we'll see if each half works on it's own
[21:04:08] <ferdna> hmmm Anniepoo__ i think the brushes are weared out
[21:04:14] <ferdna> it may be the problem
[21:04:29] <Anniepoo__> ok, I've tried
[21:04:39] <ferdna> thanks for your help :)
[21:04:58] <Anniepoo__> I can't do much if you're secretive. Does the motor run on it's own?
[21:05:07] <ferdna> Anniepoo__, no it does not
[21:05:17] <ferdna> i am not secretive at all
[21:05:21] <Anniepoo__> ok, then the motor's bad
[21:05:37] <Anniepoo__> why really isn't interesting, you can't fix it
[21:05:51] <Anniepoo__> lets look at the pump
[21:06:04] <Anniepoo__> can you rotate the pump by hand?
[21:06:13] <Anniepoo__> (probably with a tool)
[21:06:16] <ferdna> yes i can rotate the pump and motor by hand
[21:06:40] <Anniepoo__> ok, when you rotate the pump, does it suck air in the in and blow it out the out?
[21:07:01] <ferdna> i dont have the pump attached to the motor
[21:07:05] <ferdna> i am trobleshooting the motor
[21:07:14] <ferdna> if the motor doesnt spin the pump wont work
[21:07:18] <Anniepoo__> 8cD its' dead
[21:07:34] <Anniepoo__> since you don't have a motor rewinding shop, you're not gonna fix it
[21:07:54] <ferdna> yeah :(
[21:08:03] <Anniepoo__> if the pump's working, ou might be able to find a replacement motor
[21:08:16] <Anniepoo__> otherwise, it all goes in the trash
[21:08:34] <Anniepoo__> hence interest in whether the pump's working
[21:11:21] <Anniepoo__> anyway, I'm going to bed
[21:11:24] <Anniepoo__> 8cP
[21:11:39] <Anniepoo__> sorry. I'm sick.
[21:13:09] <ferdna> good night!
[21:13:14] <ferdna> hope you feel better
[21:13:18] <ferdna> Anniepoo__, thanks for the help!
[21:55:24] <ferdna> Anniepoo__, if you still there i got the motor to work!!! =)
[22:00:49] <z64555> Could you link me to the .mp4 again?
[22:01:01] <z64555> sorry, closed it by accident
[22:01:23] <z64555> nevermind, I got it
[22:03:08] <ferdna> yeah sure
[22:03:27] <ferdna> z64555, done
[22:04:40] <z64555> Ok, what's beeping?
[22:05:41] <z64555> this is a diaphragm pump, by the way. It has a similar mechanism to a piston pump, but a cylinder isn't being pushed, it's just a flexible sheet
[22:05:44] <Anniepoo__> hey
[22:06:32] <Anniepoo__> so, something's still jammed
[22:06:50] <Anniepoo__> when it stops, is there current flowing?
[22:07:21] <Anniepoo__> or is it stopping because you are turning off power?
[22:07:30] <Anniepoo__> and yes, is the beeping overcurrent?
[22:07:38] <ferdna> my power supply... that is what beeps...
[22:07:59] <ferdna> i believe is the alignment of that piece that screws to the shaft
[22:08:07] <Anniepoo__> ok, what is it communicating when it beeps?
[22:08:09] <ferdna> if i un screw it... the motor spins freely and eprfectly...
[22:08:14] <ferdna> Anniepoo__, short
[22:08:18] <ferdna> overcurrent
[22:08:19] <Anniepoo__> ah, ok
[22:08:45] <Anniepoo__> so yes, motors will look like a short if you keep them from rotating
[22:09:02] <ferdna> right
[22:09:27] <ferdna> so all i need to do is align the thing.. but dont know how
[22:09:37] <Anniepoo__> the eccentric?
[22:10:02] <z64555> that's a cam
[22:10:17] <z64555> it's used to push the rod up and down
[22:10:18] <Anniepoo__> z, I'll be quiet
[22:10:38] <z64555> Anniepoo__: relax, I'm not rue. :P
[22:10:47] <rue_shop3> !??!??!?!
[22:10:55] <z64555> ferdna: I'm not sure what you mean by alignment?
[22:11:14] <ferdna> z64555, the shaft has a flat surface...
[22:11:17] <Anniepoo__> well, it works better to have one person gi e advice
[22:11:19] <ferdna> thats where the screw goes into
[22:11:37] <ferdna> i dont remember what those screws are called
[22:11:38] <z64555> ok. So it's a keyed shaft, or a D shaft
[22:11:43] <ferdna> right
[22:11:45] <z64555> they are called set screws
[22:11:47] <Anniepoo__> setscrew
[22:11:48] <ferdna> yes!
[22:11:55] <rue_shop3> grubscrew
[22:11:57] <Tom_L> anniepoo not if it's bad advice
[22:12:05] <z64555> that doesn't have anything to do with it jamming, however
[22:12:10] <ferdna> yes it does
[22:12:14] <z64555> how so
[22:12:19] <Tom_L> rue_shop3, did you blow up the spindle yet?
[22:12:26] <ferdna> because it was screw at a position on the shaft which i dont remember where
[22:12:36] <rue_shop3> no, I'm writing the speed controller
[22:12:37] <Anniepoo__> true Tom.
[22:12:45] <z64555> uh
[22:13:00] <z64555> if it's a set screw, then it engages the flat portion of the D shaft
[22:13:00] <Tom_L> i believe everything on the interweb anyway....
[22:13:03] <Tom_L> especially here
[22:13:17] <z64555> if it's at the wrong spot, it'll just slip
[22:13:23] <ferdna> z64555, no no... another thing goes into the D part of the shaft
[22:13:56] <ferdna> i am going to remove it and look for markins on the shaft
[22:13:57] <ferdna> brb
[22:14:06] <z64555> ferdna: could you take a few pictures of it while you are doing that?
[22:14:11] <ferdna> sure!
[22:14:12] <Anniepoo__> definitely
[22:14:14] <z64555> thanks
[22:14:15] <ferdna> brb
[22:14:25] <Anniepoo__> http://www.eonsoft.us.to/downloads/vacuum_pump.mp4
[22:14:33] <rue_shop3> you can use a felt marker to 'paint' a thing to know where other things are touching it
[22:15:03] * Anniepoo__ paints rue_shop to find out where people are touching him
[22:15:19] <z64555> yeah, a sharpie, Spots where parts engage rub off the paint
[22:15:27] <Tom_L> they use dykem for that
[22:15:28] <z64555> paint/ink
[22:15:37] <Tom_L> sharpie is a poor man's dykem
[22:15:48] <z64555> dykem is the _good stuff_
[22:15:49] * rue_shop3 glares at Tom_L
[22:15:58] <Anniepoo__> P(has_sharpie) >> P(has_dykem)
[22:16:01] * Tom_L paints rue_shop3 with dykem red
[22:16:12] <rue_shop3> RED! but I want BLUE
[22:16:17] * Anniepoo__ paints Tom_L with dkyem blue
[22:16:40] <z64555> Red vs. Blue. Go go go
[22:16:45] <Anniepoo__> then scratches a line along him wih a height gage
[22:17:09] * rue_shop3 hangs a disco ball and turns the lights off
[22:17:23] <rue_shop3> THATS what the shop needs....
[22:17:32] * Tom_L turns on the blacklights
[22:17:37] * Anniepoo__ turns on loud techno
[22:17:58] * rue_shop3 explodes a few phosphor bulbs or various colours
[22:18:19] * Tom_L charges up the fog machine
[22:18:23] * Anniepoo__ is here with an outfit with lots of wearable electronics and EL wire
[22:18:27] <rue_shop3> gee, we know how to throw a party, WHO HAS THE KEGG!
[22:18:38] <rue_shop3> <-- dosn't drink
[22:18:55] <rue_shop3> when I become a robot, I plan to go off drinking completely
[22:20:46] <rue_shop3> hmm , on my tiny13 project, what PORT is my alarm pin on????
[22:20:50] * z64555 stalks to a dark corner and keeps his nose glued to the laptop screen for the rest of the day
[22:21:15] <Tom_L> party pooper
[22:21:36] <z64555> nah, I'm not bothering anybody who's not looking at me
[22:21:46] * rue_shop3 paints himself in flouescent stuff and hopes to meet someone, by just sitting somewhere drinking a tea
[22:21:46] * Anniepoo__ runs http://partyserver.rocks
[22:22:07] * Anniepoo__ shines flourescent light on rue
[22:22:44] <z64555> Anniepoo__: sure knows how to fly off the rack
[22:22:48] <rue_shop3> shop has a jukebox, online
[22:23:39] <rue_shop3> not much left, maybe I should expose it and let you guys pick me songs for a while
[22:23:58] <rue_shop3> , na, that might be worse than the random button
[22:24:13] <z64555> net enabled jukebox. hoooboy
[22:24:31] <rue_shop3> since 2001
[22:24:37] <z64555> that would be several hours of experimenting to find the most annoying song
[22:24:43] <rue_shop3> was a Pentuim1, 100Mhz
[22:24:48] <z64555> followed by that song being played for eternity
[22:24:51] <rue_shop3> no, its 1 list
[22:24:53] <rue_shop3> ...
[22:25:08] <z64555> oh!
[22:25:21] <z64555> speaking of jukeboxes, I did have the pleasure of restoring a mechanical one
[22:25:33] <rue_shop3> 1368 songs
[22:26:01] <z64555> Most of the metal parts were cast iron
[22:26:29] <z64555> well, not "most" but the large stuff. the base board and the selector arm
[22:27:24] <z64555> selector's arm was a bang-bang type manipulator, the only thing that had any moderate amount of "sensitivity" was the gripper
[22:27:53] <z64555> if it wasn't calibrated *just* so, it would break the vinyl discs quite easily
[22:28:38] <z64555> and yes, its amplifier was a tube amp
[22:28:39] <Anniepoo__> yes, I remember breaking a record playing it in a jukebox back when that was a thing
[22:29:06] * Anniepoo__ . o O ( my secrets out, I'm old )
[22:29:13] <Anniepoo__> I learned electronics on tubes
[22:29:23] <Anniepoo__> "Experimental Electronics for Young People"
[22:29:46] <Anniepoo__> I had a breadboard with fahnstock clips and octal sockets
[22:30:08] <Anniepoo__> you made a series of projects. I made a 340 V center tapped power supply
[22:30:27] <z64555> nice!
[22:30:43] <Anniepoo__> Of course I was a kid, it was all crazy. Which was pretty scary - selenium rectifiers sticking up in bare air with 340 on them
[22:30:45] <z64555> fahnstock looks way better then the stupid springs I had
[22:30:46] <rue_shop3> scarry
[22:30:56] <ferdna> back
[22:31:15] <Anniepoo__> one cool experiment I discovered on my own
[22:31:25] <ferdna> www.eonsoft.us.to/downloads/vacuum_pump_002.mp4
[22:31:35] <Anniepoo__> if you wired NE-2 neon tubes in parallel and fed them trough a resistor
[22:31:45] <ferdna> eonsoft.us.to/downloads/vacuum_pumpimg_001.jpg
[22:31:47] <ferdna> eonsoft.us.to/downloads/vacuum_pumpimg_002.jpg
[22:32:11] <rue_shop3> anniepoo, more complex cct and you could cascade them
[22:32:15] <Anniepoo__> they'd flicker at random - the selection was cosmic rays!
[22:32:55] <rue_shop3> its surprised me how much a floating adc pin can pick up on the proximity of people in the area
[22:32:56] <z64555> hm.
[22:33:22] <Anniepoo__> yup. Theremin
[22:33:28] <rue_shop3> ok the code compiles, I should be able to work out the max and min times of the duration counter
[22:33:43] <z64555> rue_shop3: oh yeah, reminds me of another experiment I had. I had made a prox sensor out of a project because it wasn't grounded
[22:33:56] <z64555> The wires in question were to a switch
[22:34:25] <z64555> Switch didn't work at all
[22:34:37] <Anniepoo__> ferd, which piece causes the binding?
[22:34:39] <z64555> but you could trigger the micro if you had your hand over the wires
[22:34:51] <rue_shop3> so I need a tiny13 to put this code on
[22:34:59] * rue_shop3 goes to sleep instead
[22:35:04] <ferdna> z64555, Anniepoo__: any ideas?
[22:36:00] <Anniepoo__> what's this cover?
http://www.eonsoft.us.to/downloads/vacuum_pumpimg_002.jpg
[22:36:28] <Anniepoo__> strip to state in this pic
http://www.eonsoft.us.to/downloads/vacuum_pump.mp4
[22:36:30] <z64555> That's a bushing
[22:36:44] <Anniepoo__> and turn by hand, looking for binding
[22:36:50] <z64555> the spot that's flattened is supposed to go up against the case
[22:36:58] <Anniepoo__> the motor sounds OK
[22:37:06] <z64555> wait? no? hm.
[22:37:25] <Anniepoo__> the big zamac casting?
[22:37:36] <Anniepoo__> with the flat on it?
[22:38:07] <z64555> yeah
[22:38:52] <z64555> I don't think it would be a counter-balance for the cam?
[22:38:55] <z64555> could it?
[22:39:10] <Anniepoo__> ferd, does that part rotate?
[22:39:49] <ferdna> yes
[22:40:05] <ferdna> i was thinking that z64555... counter balance
[22:40:36] <ferdna> Anniepoo__, it rotates with the shaft as it is screwed into it
[22:40:47] <Anniepoo__> Oh, it's a flywheel
[22:41:07] <Anniepoo__> the thing drives a pump, so it has irregular power cycle
[22:42:06] <z64555> ah, that would make sense
[22:42:54] <Anniepoo__> the flat's probably to balance the eccentric cam
[22:43:46] <z64555> eh, somewhat balance
[22:44:33] * ferdna listenning.
[22:45:07] <z64555> ferdna: the motor runs freely while it's not assembled to the rest of the pump, right?
[22:45:22] <ferdna> yes just like in the video...
[22:45:37] <ferdna> this one:
[22:45:37] <ferdna> www.eonsoft.us.to/downloads/vacuum_pump_002.mp4
[22:46:09] <z64555> I'm having trouble downloading that one, for some reason
[22:46:47] <ferdna> let me up to dropbox
[22:46:57] <ferdna> or can you dcc?
[22:47:29] <Anniepoo__> shows the shaft rotating. Sounds ok
[22:48:15] <z64555> uh, SHA's not going to do me any good, sadly
[22:48:40] <z64555> my browser just loads it a little bit, hanging frequently
[22:48:46] <ferdna> wget!
[22:49:04] <ferdna> i am on linux... dont know about you
[22:50:15] <z64555> I'm a windows peasant
[22:54:10] <ferdna> z64555, i upped to dropbox
[22:56:04] <z64555> ok, finally got it
[22:56:28] <z64555> Yeah, operation sounds good, a little grindy, but that's common
[22:58:20] <z64555> When you go to assemble it, rotate the motor shaft so that the flat side is facing the hole in the bottom of the case
[22:58:38] <z64555> and then place the other parts on it, keeping the shaft in the same position
[22:59:10] <z64555> You should be able to use a tool through that hole in the case to apply torque to the set screw
[23:00:58] <ferdna> z64555, i tried that... didnt work
[23:01:00] <ferdna> :(
[23:01:22] <z64555> what happened?
[23:01:50] <ferdna> what i showed you on the first video
[23:02:14] <ferdna> so i should screw both screws to the flat part of the D shft?
[23:02:21] <ferdna> that is what you are telling me right?
[23:02:50] <z64555> 1 moment
[23:04:30] <z64555> hm.
[23:04:38] <z64555> So there's two set screws?
[23:04:55] <ferdna> yes
[23:05:06] <ferdna> on for the small part that roatates with the ball bearing
[23:05:09] <z64555> hm, ok
[23:05:14] <ferdna> and the counter measure one
[23:05:24] <z64555> Are they the same diameter and length?
[23:05:39] <ferdna> havent take out the set screws completelly
[23:05:51] <z64555> ok, they're still in there. Keep them in
[23:06:04] <z64555> But, take out the one in the flywheel
[23:06:14] <z64555> and see if it'll go into the one in the cam
[23:06:29] <z64555> not all the way, just to see if it's the same diameter and thread
[23:06:52] <ferdna> okay one sec
[23:11:08] <ferdna> z64555, same thread same length
[23:11:14] <z64555> ok
[23:11:22] <z64555> So align the holes in both of them
[23:11:27] <ferdna> ok
[23:11:31] <z64555> but first
[23:11:37] <z64555> count the number of threads on the screw
[23:11:39] <ferdna> to the flat part of the shaft right?
[23:11:42] <z64555> yes
[23:11:54] <ferdna> on the set screw?
[23:11:56] <z64555> yes
[23:12:00] <ferdna> ok
[23:12:08] <z64555> You'll be turning that screw halfway into the cam
[23:12:23] <z64555> so that half of the screw is in the cam and the other half is in the flywheel
[23:15:37] <ferdna> z64555, i dont seem to understand
[23:17:00] <z64555> ok.
[23:17:24] <z64555> Turn the set screw into the flywheel all the way until it is flush with the hole
[23:17:46] <z64555> align the hole with the hole on the cam
[23:18:15] <z64555> gently rocke the flywheel back and forth while applying pressure on the set screw with your screwdriver/allen wrench
[23:18:42] <SpeedEvil> Whisper gently to it.
[23:18:47] <z64555> once they lock, do one to three full turns on the set screw to lock the flywheel and cam together
[23:21:07] <z64555> Ideally you want half of the set screw in the cam, with the other half in the flywheel
[23:22:21] <z64555> wait
[23:22:27] * z64555 looks at the pictures again
[23:23:13] <z64555> no, that's right
[23:24:53] <z64555> THat's an interesting way of mass-producing
[23:25:21] <z64555> can use a common lathe to produce both the cam and flywheel, vs. needing a specialized machine
[23:26:49] <ferdna> i really dont get it
[23:26:50] <ferdna> hahaha
[23:28:01] <ferdna> http://www.eonsoft.us.to/downloads/vacuum_pumpimg_003.jpg
[23:28:05] <ferdna> z64555, ^
[23:29:20] <z64555> 4 complete turns should do it
[23:29:52] <z64555> or until it bottoms out on top of the other screw
[23:30:30] <ferdna> z64555, i dont get the 4 turns...
[23:30:47] <ferdna> which ever way you turn the shaft is going to be the same
[23:31:01] <z64555> on the screwdriver/wrench
[23:31:04] <z64555> not on the part
[23:31:24] <ferdna> on the setscrew?
[23:31:26] <z64555> yes.
[23:31:39] <ferdna> the setscrew is only for securing the things to the shaft
[23:31:44] <z64555> no
[23:32:02] <z64555> The setscrew of the cam secures the cam to the shaft
[23:32:24] <z64555> the setscrew of the flywheel locks the cam and flywheel together, so they rotate together
[23:32:56] <z64555> the setscrew of the flywheel should _not_ touch the surface of the cam
[23:34:30] <z64555> They use different mechanical forces to work
[23:34:49] <z64555> In the cam, it uses pressure and frection (the D-shaft rubs against the inside of the cam)
[23:34:54] <ferdna> z64555, as i see it.... they both attach to the shaft
[23:34:55] <z64555> *friction
[23:34:59] <z64555> no
[23:35:01] <ferdna> yes
[23:35:27] <ferdna> hold on let me look again
[23:35:28] <ferdna> hehehe
[23:35:40] <z64555> lemme draw a picture
[23:36:58] <Jak_o_Shadows> Oh derp. Helps if I actually read the error message from Make
[23:43:39] <ferdna> z64555,
http://www.eonsoft.us.to/downloads/vacuum_pumpimg_004.jpg
[23:43:44] <ferdna> look at that setscrew
[23:44:35] <ace4016> that image loads sideways....
[23:44:37] <ace4016> that's new
[23:44:40] <rue_shop3> hey, I can open an image
[23:45:06] <rue_shop3> set screw hits shaft, whats problem?
[23:45:15] <rue_shop3> thats not spinning is it?
[23:45:22] <rue_shop3> looks horridly off balance
[23:45:36] <ferdna> rue_shop3, z64555 says that it scres into the cam
[23:45:43] <ferdna> not into the shaft
[23:46:05] <z64555> hm
[23:46:19] <z64555> ok now I see it
[23:46:38] <Anniepoo_> yup, flywheel
[23:46:39] <z64555> I had thought that the hole in the flywheel was on the flat
[23:46:58] <ferdna> yes is on the flat part of that piece
[23:47:00] <z64555> Well, it is. but it goes all the way through, instead of just the rim
[23:47:28] * z64555 trashes a picture he made in 15 minutes
[23:47:31] <rue_shop3> threading is a bit short, does the grubscrew seat on the flat right?
[23:47:38] <ferdna> yes
[23:47:52] <ferdna> rue_shop3, the shaft has a flat too
[23:47:53] <rue_shop3> if not, drop a short peice of round bar into it
[23:47:59] <rue_shop3> k
[23:48:13] <rue_shop3> ok i got apples and apples
[23:48:25] <rue_shop3> now I just need to compare them, and convert them to ornages
[23:48:25] <ferdna> z64555, any other ideas???
[23:48:36] <rue_shop3> what problem are you having again?
[23:48:47] <rue_shop3> I cant do videos here
[23:49:01] <ferdna> rue_shop3, shit i was going to paste url
[23:49:04] <z64555> rue_shop3: the motor jams up
[23:49:11] <z64555> runs a bit, then jams
[23:49:21] <rue_shop3> is it a piston pump?
[23:49:30] <z64555> piston actuated diaphram, yeah
[23:49:41] <rue_shop3> heat, piston is jambing
[23:49:54] <rue_shop3> tolerance is too tight
[23:50:00] <z64555> after less than a few seconds of being on?
[23:50:01] <rue_shop3> ?
[23:50:04] <rue_shop3> yea
[23:50:08] <z64555> huh.
[23:50:21] <rue_shop3> cools down and it ok for another few seconds?
[23:50:25] <ferdna> rue_shop3, if you can www.eonsoft.us.to/downloads/vacuum_pump.mp4
[23:50:29] <rue_shop3> no videos
[23:50:32] <ferdna> i know
[23:50:33] <rue_shop3> use your words! :)
[23:50:37] <ferdna> but there is no other way
[23:50:45] <rue_shop3> cools down and it ok for another few seconds?
[23:51:01] <z64555> powersupply stops on overcurrent, not sure if its still supply power or not
[23:51:18] <rue_shop3> but its ok for a few strokes of it?
[23:51:21] <z64555> yeah
[23:51:29] <rue_shop3> really cheap pump?
[23:51:30] <z64555> after reset of power supply, works a bit again
[23:51:34] <z64555> ...pretty much
[23:51:38] <rue_shop3> yea
[23:51:57] <rue_shop3> not enough room for the piston, it heats up, expands, jams
[23:52:04] <ferdna> lol no
[23:52:07] <rue_shop3> 12V?
[23:52:10] <ferdna> yes
[23:52:21] <rue_shop3> what happens if you put it on a car battery for a bit?
[23:52:32] <rue_shop3> car things are awefull, pull 10-20A idle
[23:52:36] <ferdna> it doesnt generate heat... is not that strong... the motor jams...
[23:52:58] <z64555> only when it's assembled to the rest of the machine
[23:53:11] <z64555> the heat is around the piston ring and the chamber
[23:53:29] <z64555> it's a fast heat, so the chamber and other parts don't have time to absorb it
[23:53:42] <z64555> since the piston ring is probably rubber, which is an insulator
[23:54:11] <z64555> you won't be able to check the temp of the ring without taking apart. but you might be able to stick a finger on the underside of the piston to check it
[23:54:31] <z64555> anyway.
[23:54:38] <ferdna> i got a laser temp
[23:54:43] <z64555> ferdna: do you have lithium grease
[23:54:58] <ferdna> no
[23:54:59] <z64555> or maybe petroleum jelly
[23:55:01] <ferdna> yes
[23:55:03] <z64555> ok
[23:55:15] <z64555> slather a dab of that on the ring and the inside of the cylinder
[23:55:21] <z64555> just enough to wet it
[23:55:50] <z64555> try not to put anything on the top of the piston nor the diaphram
[23:56:50] <ferdna> :(
[23:56:56] <z64555> ?
[23:57:05] <ferdna> i am going to make a mess
[23:57:21] <z64555> that's life with machines
