[00:00:04] <PetefromTn_> I must admit it is kind of resourceful of them to locate a local machinist and try to get it fixed for the customer quickly.
[00:00:11] <jdh> yep
[00:00:31] <PetefromTn_> We shall see how it goes I guess.
[00:00:36] <jdh> don't pay for any materials up front :)
[00:00:44] <PetefromTn_> there are no materials
[00:01:08] <PetefromTn_> it is apparently some kind of arm that needs to be machined with some holes in different locations.
[00:01:38] <PetefromTn_> the one they sent had the holes in a different spot it sounds like
[00:02:28] <jdh> should have had a 3d model

[00:25:14] <andypugh> That is exactly the sort of thing that assembling a 3D model shows you.
[00:25:27] <PetefromTn_> heh
[00:25:52] -!- skorasaurus has quit [Quit: WeeChat 1.0.1]
[00:28:10] <andypugh> Of course it’s a bit like touch-typing, really useful if you alredy know how to do it, but possibly not worth the pain of learning if you don’t. I had a full-time 3D CAD job for a while.

[00:34:33] <PetefromTn_> yeah I have a LOT to learn about it but I have been able to model everything I needed to so far. thank God for youtube tutorials.
[00:36:04] <CaptHindsight> whenever I put anything on Craigslist I get text bombed
[00:36:16] <PetefromTn_> yeah it sucks huh.
[00:36:42] <PetefromTn_> I get email bombed all the time with smartasses for some reason
[00:37:01] <CaptHindsight> there are online services that do it for you
[00:37:12] <PetefromTn_> do what
[00:37:28] <CaptHindsight> text bomb
[00:37:33] <PetefromTn_> oh yeah
[00:38:17] <CaptHindsight> I amazed at the apathy, and free time on their hands. These people must feel powerless and it's the only attention that they can get.
[00:38:23] <PetefromTn_> I get calls from all kinda BS call centers it is just a fact of life today I think..
[00:39:39] -!- erictheise has quit [Quit: erictheise]
[00:40:16] <PetefromTn_> There are people who just do it for fun. I was selling my car while back and some jackass in Florida texted me wanting to buy it. Went thru about a dozen texts before I realized it was BS and then he just laughed when I called him surprised he bothered to answer. There are losers everywhere with nothing better to do.
[00:42:07] <CaptHindsight> that what gets me is that this is what they decide to do for entertainment
[00:42:21] <PetefromTn_> I hear ya.
[00:42:32] <CaptHindsight> I can understand if you're 11
[00:42:43] <PetefromTn_> oh this guy sounded at least 20
[00:42:43] <CaptHindsight> we used to make prank phone calls

[00:43:19] <CaptHindsight> yeah, but at 20+ it's pretty sad
[00:43:30] <PetefromTn_> I think I tried that once when I was like 12 but I was not very good at it.. :P
[00:44:10] <CaptHindsight> we used to try an get people to pull their cords out of the phone....
[00:44:34] <CaptHindsight> tell them that the wires we hanbing too low and it would save us on a service call
[00:44:36] <PetefromTn_> anyone catch the meteor showers yesterday?
[00:45:02] <CaptHindsight> surprised by how often that worked
[00:45:17] <CaptHindsight> nah, it's been overcast and foggy for the past 4 weeks
[00:45:27] <PetefromTn_> where are you again?
[00:45:35] <CaptHindsight> we won't see stars or sun till maybe March
[00:45:40] <CaptHindsight> Chicago
[00:45:48] <PetefromTn_> oh
[00:45:53] <jdh> 68f and sunny here today... being at work sucked.

[00:47:09] <CaptHindsight> 30's overcast rain, fog, depression :)
[00:47:23] <jdh> move!
[00:47:37] <jdh> I know where you can get a house with a VMC in east tennessee
[00:47:38] <CaptHindsight> by jan we'll have -15 and some sun
[00:47:45] -!- tekniq_ has quit [Ping timeout: 258 seconds]
[00:48:27] <PetefromTn_> sure as hell can LOL
[00:48:32] <CaptHindsight> I'll probably end up in Taiwan and Japan
[00:48:56] <CaptHindsight> China is fun, but it wears on me after a few weeks

[01:40:04] <FinboySlick> 'sup Pete?
[01:40:06] <PetefromTn_> LOL
[01:40:32] <PetefromTn_> meh not much just working on some drawings right now.
[01:41:15] <FinboySlick> Oooh, I've been itching to do cad for a while now. You're lucky I'm not local, I'd force you to let me do them.
[01:41:45] <PetefromTn_> hehe I need to do them myself really so I can learn

[01:45:47] <XXCoder> wow thats pretty small
[01:45:56] <XXCoder> if it wasnt billion miles away I;d get it for fun lol
[01:46:02] <PetefromTn_> cnc wood lathe?
[01:46:41] <mozmck> that's what it looks like - kind of interesting.
[01:46:42] <XXCoder> it has vaccum gfor wood so yes I would say?
[01:46:48] <XXCoder> check out 4th pic
[01:47:09] <mozmck> that spindle nose is a standard wood lathe spindle
[01:47:50] <PetefromTn_> yeah it looks that way.
[01:48:00] <PetefromTn_> Check this one out... http://westmd.craigslist.org/tls/4797779714.html
[01:48:27] <XXCoder> its darn small though
[01:48:33] <XXCoder> 3 in dim, maybe 2 ft long
[01:49:10] <XXCoder> you probably can run it make wood dilios so women (and some men I guess?) some hard wood :P
[01:51:27] <mozmck> that's disgusting.
[01:51:44] <XXCoder> its okay if you dont like hard wood. most men dont

[02:00:41] <XXCoder> pretty expensive heh
[02:00:59] <PetefromTn_> yeah especially considering it does not actually work.
[02:00:59] <FinboySlick> PetefromTn_: At that price, fit this one in: http://www.ebay.com/itm/MAZAK-Microslant-15-CNC-Lathe-Tool-Turret-2-Axis-Way-Assembly/141187257333?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D27538%26meid%3D26c9e26ece6f44de932ef0cc2b46f12f%26pid%3D100005%26prg%3D11353%26rk%3D2%26rkt%3D6%26sd%3D320597843678&rt=nc
[02:01:26] <FinboySlick> Then it can mill and do funky stuff.
[02:01:34] -!- anth0ny has quit [Quit: anth0ny]
[02:01:43] <PetefromTn_> that looks like a monstrously heavy bitch
[02:02:31] <PetefromTn_> I do like the thru turret coolant setup on it tho.
[02:03:42] <FinboySlick> It has hassle-free returns too. But I have a feeling it wouldn't be a hassle-free installation.
[02:04:38] <FinboySlick> BRB, this new kernel is messed up.

[02:04:58] <PetefromTn_> unfortunately real expensive too.

[02:10:57] <XXCoder> too bad
[02:11:35] <PetefromTn_> http://knoxville.craigslist.org/tls/4808573661.html
[02:15:30] <JP1> Well i just finished calibraing a delta what a tedious task
[02:15:54] <JP1> calibrating
[02:16:12] <Jymm> JP1: Delta --> http://cdmsmith.com/en-US/Insights/Features/-/media/Images/Insights/people-progress/674x315/CDM_people_progress_Stockton_California_3_United_States_delta_aerial_674x315.ashx
[02:17:14] <FinboySlick> Jymm: Those are very hard to calibrate.
[02:17:26] -!- anth0ny has quit [Client Quit]
[02:20:21] <XXCoder> no automated calbratiob?
[02:21:18] <JP1> There are but it just masks issues you should deal with in the first place
[02:22:39] <JP1> Havent delalt with deltas alot so it was a bit of a curve. after some understanding it was pretty straightforward.
[02:23:09] <XXCoder> lol break game records with "personal massager" https://www.youtube.com/watch?feature=player_embedded&v=qWpHDqFwgC4
[02:23:20] <XXCoder> JP1: interesting
[02:23:39] <JP1> Most of the time was spen understanding the relationships of parametes related to kinematics
[02:25:08] <Jymm> FinboySlick: Unless you are Mohamed =)
[02:25:11] <XXCoder> be back
[02:25:48] <Jymm> FinboySlick: or have lots of explosives
[02:26:26] <Jymm> Flipp__: and lawyers
[02:26:31] <FinboySlick> Jymm: Bad choice of words to put in consecutive sentences. NSA is all over you now ;)
[02:26:58] <Jymm> FinboySlick: Who cares about the NSA, it's the EPA that would go all ape shit on ya
[02:27:00] <Valen> lol the face on the dude is *soooo* intense XXCoder
[02:27:39] <FinboySlick> Japan...
[02:27:53] <FinboySlick> Now I want to watch Silent Library again.
[02:29:38] <PetefromTn_> still have not been able to figure out what the motor frame size is for the CNC lathe I bought.
[02:29:54] <FinboySlick> https://www.youtube.com/watch?v=4NS0F9dKMjQ
[02:29:59] <PetefromTn_> http://www.grainger.com/tps/motors_nema_motor_dimensional_chart.pdf
[02:30:12] <PetefromTn_> according to this I THOUGHT it was a 184TC
[02:30:28] <PetefromTn_> but the hole diameter is actually like 7 1/8 inches across
[02:30:38] <PetefromTn_> and the bolt pattern circle is like 8.5"
[02:30:50] <PetefromTn_> just the opposite of what the chart says
[02:32:04] <PetefromTn_> err what they are calling the rabbett diameter on my motor mount is 7.125" and the bolt circle is about 8.5 or so
[02:32:25] <PetefromTn_> http://www.ebay.com/itm/RELIANCE-P18F1015-DC-AC-5HP-230-460V-AC-184TC-1715RPM-3PH-ELECTRIC-MOTOR-D238645/301408945488?_trksid=p2054897.c100204.m3164&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140407115239%26meid%3D868d76bba21e48a8b6ab663182262b71%26pid%3D100204%26prg%3D20140407115239%26rk%3D15%26rkt%3D30%26sd%3D201169039634
[02:32:34] <PetefromTn_> this is a suitable motor if it would fit LOL>
[02:33:51] <Jymm> WHAT THE HELL... https://www.youtube.com/watch?v=lRdIDCWFunI
[02:34:32] <Valen> I have the sneaking suspicion that wasn't a real library FinboySlick
[02:35:09] <FinboySlick> It wasn't, it's just a setting for the game.
[02:35:37] <Valen> Jymm: lipo batteries are pretty good these days
[02:35:57] <Jymm> Valen: DAMN 500+ reviews... http://www.amazon.com/PowerAll-PBJS12000R-Rosso-Portable-Starter/dp/B00D42AFS8#customerReviews
[02:36:03] <FinboySlick> The punishments are stupid but I somehow laugh every time.
[02:36:11] <FinboySlick> Especially the slapping machine.
[02:37:05] <FinboySlick> Jymm: https://www.youtube.com/watch?v=z3x_kYq3mHM This guy hacked it together with supercapacitors.
[02:38:05] <FinboySlick> Obviously, his test bench isn't a hemi v8 but still, it's neat.
[02:38:10] <Jymm> FinboySlick: Those I've seen
[02:39:28] <renesis> whats leakage like?
[02:39:35] <Jymm> FinboySlick: I just don't know the life of those caps
[02:40:26] <renesis> if they cant hold charge for months its not a replacement
[02:40:36] <FinboySlick> Jymm: I imagine it can't be worse than chemical batteries.
[02:41:14] <Jymm> FinboySlick: I want 20+ years, and to remain charged for 6+ months
[02:41:15] <renesis> yeah but if they leak charge they wont start your car if you leave it for a week
[02:41:50] <FinboySlick> renesis: They leak a fair bit but they'll last a weekend apparently.
[02:42:00] <XXCoder> Valen: indeed lol

[04:40:52] <XXCoder> havent seen you ask your question there?
[04:41:26] <Benjamin23> where
[04:41:27] <Benjamin23> what
[04:41:34] <Benjamin23> ##linux?
[04:41:59] <Benjamin23> event after registering, asshole machine nickserv says it cannot send to channel
[04:42:07] <Benjamin23> sorry I am pissed
[04:42:18] <Benjamin23> this e2fsck is really kicking my ass
[04:42:20] <XXCoder> ohh its one of those channels you need to be registered

[04:45:51] <FinboySlick> Benjamin23: I'm not sure what your question really involves but my guess is that your vfat formatted usb stick contains a squashfs filesystem image which is where your linux system is.
[04:46:35] <FinboySlick> Benjamin23: I only have a few minutes but what are you trying to do?
[04:47:14] <Benjamin23> FinboySlick: yes that is correct

[16:27:12] <lair82> Ok, I looked at the diagram for the 7i48, and was kind of figuring that's what it would be. Do I need to do anything with the jumpers on that card?
[16:28:25] <pcw_home> jumpers set the differential/TTL mode of the inputs
[16:29:37] <pcw_home> (like the 7I48 inputs)
[16:31:32] <lair82> I see, just jumped back to the 7i48 pdf, and clear as can be now.
[16:38:14] <lair82> Thanks Peter,

[16:54:34] <PetefromTn_> I am running a couple hundred small simple parts 7 at a time here and this is kinda enjoyable.. I can watch TV while the machine is running them and just pop out there here and there to replace materials. Too bad I can't get this kind of work all the time LOL
[16:56:26] <archivist> be glad you are not standing at a capstan lathe all day :)
[16:59:33] <PetefromTn_> I can
[16:59:46] <PetefromTn_> can't wait to be standing at my CNC lathe running that thing soon
[17:00:59] <skunkworks> The collet on the K&T jammed yesterday.. This has happened a few time before be after some fiddling it would release. This time it didn't. Dad was able to loosen the nose of the spindle and useing the pull holes add some extra pressure to the tool. then it released. We need to check the cylinder - we wonder if it has excesive leak by.. (it should push 6 tons..)
[17:01:16] <PetefromTn_> ordered a bunch of 6061 plate yesterday for another customers project

[17:14:50] <jdh> is normal 6oz or 20?
[17:14:56] <PetefromTn_> nice to have a complete backup spindle ready to rock
[17:15:23] <skunkworks> I think that was the tool in the spindle since the machine was taken out of service in the mid 80's - notice the dirt from when it was dumped into the junkyard..

[17:18:11] <skunkworks> heh
[17:19:01] <SpeedEvil> It's probably when you start seriously considering making your own ball bearings that you may have enough tools.
[17:19:02] <skunkworks> We have never looked at replacements.. it certainly limits the rpm... around 3000rpm is the limit

[17:19:20] <skunkworks> (heat wise)
[17:19:33] <andypugh> My spindle can only do 1500, and the bearings get very hot at that speed!
[17:19:44] <PetefromTn_> jeez that kinda sucks
[17:19:57] <skunkworks> the original hydraulic servo setup went to 2400rpm
[17:20:01] <PetefromTn_> but honestly my spindle is not exactly fast either at max 6k
[17:20:18] <skunkworks> we have a matsurra now with a 6k spindle.. it helps
[17:20:23] <andypugh> I wonder if the preload is too high on my spindle.
[17:20:42] <skunkworks> I would guess.. are they timken?
[17:20:44] <PetefromTn_> I would think any bearing that is getting hot is not setup correctly
[17:20:58] <PetefromTn_> or not lubed properly
[17:21:14] -!- b_b has quit [Remote host closed the connection]
[17:21:14] <PetefromTn_> even plain roller bearings can easily do 1500 RPM
[17:22:05] <andypugh> I _think_ the bearings are Fafnir, and they are lubricated with the specified NLG3 grease
[17:22:54] <PetefromTn_> fafnir makes a fine bearing there is probably something wrong there with the setup

[18:26:43] <malcom2073> Indeed, tampering with or in any way affecting the operation of (blocking signals for wireless readers) is in some places a felony
[18:27:04] <Rab> zeeshan, do some testing. Move the radio across the garage and see if anything changes.
[18:27:19] <zeeshan> i did
[18:27:25] <zeeshan> its louder when its next to the wall
[18:27:29] <zeeshan> closest to the meter
[18:27:39] <zeeshan> and quieter but still noticeable when 20 feet from that wall
[18:27:41] <zeeshan> across the garage
[18:27:42] <Rab> Very suspicious.
[18:27:52] <zeeshan> when i put my cell phone next to it
[18:27:54] <zeeshan> and make a call
[18:27:59] <zeeshan> like 1" away, it goes crazy too
[18:28:04] <zeeshan> but 2 feet away
[18:28:05] <zeeshan> its okay
[18:28:23] <Connor> I have a smart meter now..
[18:28:25] <zeeshan> i just found it interesting
[18:28:36] <zeeshan> its kinda annoying cause it happens every 15 seconds
[18:28:55] <Rab> IIRC some smart meter systems are cellular, some use other RF bands and some update over the power line itself.
[18:29:18] <zeeshan> im gonna put some aluminum foil on the wall
[18:29:24] <zeeshan> and see if it blocks it :P
[18:30:00] <Rab> zeeshan, see if you can identify the model of your meter and discover how it broadcasts data.

[20:02:18] <renesis> meh, china LEDs
[20:02:47] <Jymm> renesis: As opposed to what, australia =)
[20:03:24] <renesis> as opposed to sourcing from domestic distributors from domestic companies, china LEDs work but they usually dont last nearly as long
[20:03:47] <Jymm> renesis: For $3.38 USD, I think I can take my chances.
[20:03:55] <renesis> even if the LEDs were made in .cn, QA is going to be better if through domestic companies
[20:04:21] <renesis> yeah thats not bad

[20:07:01] <Jymm> that one
[20:07:17] <renesis> yeah maybe shopped, cant tell
[20:08:10] <Jymm> renesis: No biggy. Just need to find a driver that can do PWM
[20:08:45] <renesis> $.50 avr + some logic fet
[20:09:02] <Jymm> renesis: CC ?
[20:09:10] <renesis> led supply makes some stuff, i think it might be switch mode current regulating, not really pwm
[20:09:29] pinkfloyd is now known as il
[20:09:29] <Jymm> renesis: difference being?
[20:09:38] <renesis> well, if you put a constant current source on it i guess
[20:09:47] <renesis> take you a couple more transistors
[20:09:53] <Jymm> heh
[20:09:57] <renesis> jymm: money, amount of work?
[20:10:11] <renesis> youll have to program the avr and put it on a board or something
[20:10:24] <renesis> simple enough to deadbug onto some unclad perfboard
[20:10:27] <Jymm> renesis: Constant current stuff kinda throws me a curve
[20:10:40] <Jymm> I get it, but I don't.
[20:10:47] <renesis> for switch mode supplys it just uses a low side sense resistor for feedback
[20:10:55] <renesis> instead of using output voltage
[20:11:04] <renesis> thats literally the only diff
[20:11:19] <Jymm> ah
[20:11:30] <Jymm> just how they sense the current/load
[20:11:40] <renesis> so you set your error amp ref voltage to the sense resistor voltage for whatever current you want
[20:11:46] <renesis> yeah
[20:12:08] <renesis> then you can pwm that to adjust brightness, or change the ref voltage
[20:12:36] <renesis> you can do linear current sinks and sources, too
[20:12:38] <Jymm> renesis: Yeah, I just want it usefu even when bat is down to 10V by lowering the outpur.
[20:12:41] <PCW> efficient constant current requires an inductor
[20:13:01] <Jymm> buck/boost
[20:13:03] <renesis> with a pair of bjt transistor, uses Vbe of one as the current ref, not as efficient, can be sensitive to values
[20:13:16] <renesis> pcw: right because switching supply
[20:13:35] <Jymm> renesis: drivers are plentiful, just need to find the right one for this
[20:13:58] <renesis> jymm: its basically a dc to dc converter so should be very efficient dealing with changing input voltage
[20:14:09] <renesis> compared to some linear vreg and resistor setup
[20:14:29] <renesis> ledsupply has bunch of modules for that size LED
[20:14:57] <Jymm> renesis: Yeah. I just wan the added low voltage features and strobing effects. Thought a arduino might be nice

[20:15:55] <renesis> ive never used an arduino, ive done lots of projects on avrs, arduino has lots of shit i dont need for most projects
[20:16:03] <renesis> should learn it for contract type work, tho
[20:16:25] <renesis> yeah, an 8dip ATtiny would work for this
[20:16:41] <Jymm> renesis: http://www.instructables.com/id/Digispark-DIY-The-smallest-USB-Arduino/
[20:16:52] <renesis> you can stick one of those on a ledsupply module, have the avr do pwm and blinks or whatever
[20:17:06] <renesis> some of the modules have enable inputs that you can pwm
[20:17:36] <renesis> yeah thats not a usb arduino
[20:17:37] <Jymm> renesis: Yep, might be fun with 4 or 6 of those LEd strips
[20:17:46] <renesis> thats just an attiny with a atmel programming dongle
[20:17:55] <renesis> this is kind of why the arduino community pisses me off
[20:17:59] <Jymm> renesis: Yeah, it is. It plugs indirectly to USB port
[20:18:12] <Jymm> space^
[20:18:13] <renesis> yeah, i has it somewhere, good buy
[20:18:38] <Jymm> renesis: I mentioned it for your contracting stuff
[20:19:03] <Jymm> renesis: if you only need 4 pins that is
[20:19:08] <renesis> yeah, ive done stuff like that for people
[20:20:06] <renesis> cnc pcb, a little dip avr and connectors for LED modules or little display for temp or whatever
[20:20:15] <Jymm> renesis: Anyhow, that's what I was thinking for a fun flood light project. Toss on a tripod or universal mount
[20:20:48] <renesis> easiest would prob just be an led supply module and a pot for brightness
[20:21:14] <Jymm> renesis: would that preserve battery life though?
[20:21:17] <renesis> the avr you can add a button and do strobe shit
[20:21:42] <renesis> pretty sure because its constant current buck supply
[20:22:13] <Jymm> at 1100 Lumen, you could PWM (duty cycle) it, and get some nice life out of a battery charge.
[20:22:23] <renesis> you dont kill efficiency when you lower current so should reduce battery usage, but would check idly current of the modules in the datasheet

[20:23:27] <renesis> yeah, ive heard that if you pulse at very high current, percieved light is more than if you were to sustain current at same energy consumption per period
[20:23:56] <renesis> i dunno if thats true or significant enough to matter, kind of gerts into neurology, heheh
[20:24:04] <Jymm> renesis: Only way to detect it is with a video camera that I've ever come across.
[20:24:33] <renesis> oh, yeah that totally depends on a ton of things but it usually does something
[20:24:34] <Jymm> great way to check IR remote controls too =)
[20:24:50] <renesis> haha @ videos of new exotics, their tail lights look like theyre sparking inside or something
[20:25:04] <Jymm> heh
[20:25:54] <renesis> but if you dont perceive the pulsed light as more than sustained light, its a waste
[20:26:28] <renesis> but i think there is retina burn stuff at play, like the light goes away but your optical nerves still stuck a bit
[20:26:36] <Jymm> Well, equal to at (let's say 80% duty cycle, works for me. doesn't have to be "more".
[20:26:41] <renesis> at 50-100hz i would be surprised if this was the case
[20:27:01] <Jymm> could easily play witht he waveform too
[20:27:04] <renesis> right you might not miss the 20% enough to notice its being pulses
[20:27:07] <renesis> pulsed
[20:27:23] <Jymm> yep, while still conversing battery life.
[20:27:43] <renesis> i would try much more agressive duty cycle reduction at higher frequencies

[20:28:40] <renesis> its almost a sociology type project tho, because subjective
[20:28:55] <Jymm> what subjective?
[20:29:05] <renesis> you have to gauge perception of light, heh
[20:29:09] <Jymm> the PWM or one year led?
[20:29:18] <Jymm> ah
[20:29:22] <renesis> so if youre just testing yourself, whatever
[20:29:39] <renesis> but if youre trying to write a peper, you prob want to blind test a bunch of people

[22:03:45] <andypugh> It seems to be a failure for that application. When the antenna amp is powered from the switcher (even with all the suggested caps around it) the antenna never gets a clean signal.
[22:04:03] <andypugh> So, I guess it puts noise in the 60kHz band.
[22:06:00] <PCW> Yeah probably quite a noise radiator
[22:06:39] <andypugh> I suspect I would be better off with a linear regulator running off the 25-ish V rectified power.

[22:07:52] <Tom_itx> 1k F or so
[22:08:41] <Tom_itx> every time it pinged the C would reset without the cap
[22:08:57] <andypugh> The problem here is that I _really_ want to avoid caps beacause they die, and this thing is planned to last decades.
[22:10:34] <Tom_itx> well any regulated supply is going to require some sort of caps
[22:10:47] <Tom_itx> whether it's smps or linear
[22:11:03] <Rab> Yeah, I don't think that's something you can avoid. Just use quality name-brand caps, well-derated for the working voltage.
[22:11:53] <Rab> Caps die when they're poorly made or poorly specced. Derated, high-reliability types should last as long as anything else.
[22:12:03] <Jymm> andypugh: soild caps?
[22:12:31] <Jymm> andypugh: Heh, MAKE your own caps =)
[22:13:09] <Rab> For longevity, I would choose a linear regulator with diode protection and lots of bulk capacitance over a SMPS. I've seen lots of examples of that topology last for 40 years and counting.
[22:13:13] <Tom_itx> a bunch of largish ceramics in parallel may last longer than electrylytic
[22:13:43] <Rab> Film caps should last forever. Bulk and expense for serious capacitance are the downsides.
[22:13:50] <andypugh> The mica cap on the magneto of my Ner-a-car is 90 years old and still works. But it is mica and copper sheets rivitted together.

[22:26:51] -!- ariscop has quit [Quit: Leaving]
[22:27:02] <andypugh> I probably need to charge a cap to 40V from the 24V side, but through a diode so it doesn’t die when the solenoid pulse happens.

[22:31:35] <Jymm> andypugh: How far is the antenna from the Rx?
[22:32:16] <andypugh> About 2”
[22:32:27] <Jymm> Then why do you need an amp?
[22:32:42] <andypugh> The Rx is the amp
[22:32:53] <andypugh> The output from the amp is TTL logic.
[22:33:04] -!- jduhls_ has quit [Quit: Leaving]
[22:33:17] <Jymm> so it's not a Rf signal amp

[22:43:47] <Jymm> Oh, AM
[22:44:06] <andypugh> I think that RF noise up the power supply wires is likely to be the problem.
[22:44:37] <Jymm> andypugh: and the leads twisted?
[22:44:42] <Jymm> are*
[22:44:48] <andypugh> Yes

[22:45:32] <andypugh> The A-B-A test on the pwer supply seems to suggest that that is the problem, I will just build a linear one.
[22:45:46] <Jymm> andypugh: All I could suggest is make a AM antenna out of hookup wire and use a shielded feedline

[22:52:01] <PCW> you may need higher input voltage regulator that a 7805
[22:52:01] <andypugh> I looked into it. But you need a _lot_ of wire for 60kHz
[22:52:27] -!- zeitue has quit [Ping timeout: 272 seconds]
[22:52:31] <Jymm> andypugh: You are just Rx, not Tx. You don't need to get exactly half or qtr wave
[22:53:43] <andypugh> PCW: I would have to check the specs, certainly. And the PowerPax is a neat little thing for another project.
[22:54:52] <Jymm> andypugh: Great gp antenna, and can even Tx on the 144/440MHz bands http://www.maplin.co.uk/p/scanking-discone-antenna-qt28f
[22:55:11] <Jymm> andypugh: Not a lot of gain, but wide bandwidth.
[22:55:28] <PCW> 7805s are 35V max so series zener or different regulator
[22:55:29] <Jymm> well zero gain actually =)
[22:55:50] <andypugh> Jymm: 60 k Hz !
[22:56:06] <andypugh> That’s a 25 MHz antenna
[22:56:07] <Jymm> andypugh: Yes, and that one goes down to 25Mhz
[22:56:17] <Jymm> andypugh: up to 1500MHz
[22:56:37] <andypugh> So only 3 orders of magnitude too high?
[22:56:59] <Jymm> andypugh: it's a broad band antenna, 25 to 1500 MHz
[22:57:17] <andypugh> Yes, and 60kHz is _way_ outside that broad band.
[22:57:36] <Jymm> andypugh: Anyhow, just make an antenna like the pic
[22:57:44] <Jymm> oh Kilo.
[22:57:50] -!- bedah has quit [Remote host closed the connection]
[22:57:53] <andypugh> And, that ferrite is tuned to 60kHz (fixed) for the job at hand.
[22:58:12] <Jymm> andypugh: For Rx, it's not that big of a deal, really.
[22:58:38] <Jymm> Tx is another story.
[22:58:46] <andypugh> I think that the ferrite might be the only tuner in the set.
[22:59:08] <Jymm> andypugh: Just try it,
[22:59:12] <andypugh> (Ah, no, there is a crystal on the oard isn’t there)
[22:59:30] <andypugh> How many times do I have to say that it works as it is?
[22:59:35] <Jymm> solid hookup wire, the more coild you have the better the gain
[22:59:52] <Jymm> andypugh: it might overcome your RFI issue
[23:01:16] -!- jvrousseau has quit [Quit: Textual IRC Client: www.textualapp.com]
[23:01:34] <Jymm> The larger the loop the better, but 6-12" should be good.

[23:46:21] <anonimasu> PCW: got both axes working now(alot of tuning left)
[23:47:13] <anonimasu> I've got a question for you, I have some 9v encoders can i hook them up into the 7i47
[23:47:44] <PCW> for torque mode drives you probably need to set your servo thread as fast as you can go
[23:47:49] <CaptHindsight> gadzooks, gas is down to $2.07/gal here today
[23:47:53] <The_Ball> Not strictly on topic, but I did use LinuxCNC to make the brackets: https://wigen.net/owncloud/public.php?service=files&t=9a47cf8bec07e60daea0ecdb7ddc93d5 and https://wigen.net/owncloud/public.php?service=files&t=75248e8a4fcc084a7906a7855ed7b08c
[23:48:15] <Jymm> CaptHindsight: Please, take this perosnally... FUCK YOU! lol
[23:48:27] <PCW> Single ended 9V?
[23:48:45] <anonimasu> yeah
[23:49:05] <Jymm> CaptHindsight: (I say the same thing to the gf when she fills her tank for $20)
[23:49:55] <CaptHindsight> <$2/gal in Tulsa
[23:50:11] <PCW> if you disable the 7I47 input terminationa and tie the -inputs to 5V it _should_ work
[23:50:24] <Jymm> CaptHindsight: Usually $75 for me on avg
[23:50:26] <anonimasu> it wont fry will it?
[23:50:35] <PCW> well.....
[23:51:31] <Jymm> CaptHindsight: If it got to $1.99, I'd be there with 55gal drums in the back =)
[23:51:48] <anonimasu> it says 12v, common mode voltage, but I am bad with opamps
[23:52:09] <CaptHindsight> Jymm: http://www.gasbuddy.com/gb_gastemperaturemap.aspx
[23:52:11] <PCW> inputs are rated abs max +-25V
[23:52:33] <CaptHindsight> Jymm: you get the nice weather, we get cheap gas
[23:52:43] <anonimasu> as long as I wont kill the board I will manage to get that working(I have 9v for the other encoders also)
[23:53:10] <anonimasu> but only as VCC for them, the signal is a differential signal
[23:53:40] <PCW> 5V is close to the ideal 4.5V (1/2 way)
[23:54:00] <Jymm> CaptHindsight: Heh, I hit safeway as we get up to $1 off per gallon based on grocery purchases.
[23:55:10] <anonimasu> PCW: I had noise issues at first for the stegmann encoders, until I put a 50ohm resistor on both of the wires(as the diff receiver circuit in the stegmann docs
[23:55:13] <Jymm> $2.59 right now.
[23:55:31] <Jymm> anonimasu: twisted leads?
[23:55:34] <anonimasu> yep
[23:55:37] <Jymm> k
[23:55:44] <anonimasu> (this is a pre-built table with fried control)

[23:55:57] KimK_ is now known as KimK_unit1
[23:56:34] <Jymm> CaptHindsight: I need PropaneBuddy website =)
[23:57:19] <anonimasu> so signal in on the RXx (The 9v one) and then 5V on RXx/
[23:58:59] <anonimasu> and gnd, between the encoder powersupply and the 7i47
[23:59:26] * anonimasu will read in tomorrow
