[00:16:25] <Cromaglious> they are touch gauges with induction sensor in them
[00:18:15] <Cromaglious> or a coil with a movable slug connected to the lever tip
[00:18:57] <Cromaglious> http://www.emigage.com/images/precitech8150_1.jpg is one
[00:19:51] <dirty_d> how accurate is it supposed to be?
[00:20:06] <Cromaglious> damn accurate
[00:20:16] <dirty_d> and how do you calibrate it? two known height things, and interpolate between?

[01:37:23] <zeeshan> haha
[01:37:25] <zeeshan> that guy is retarded
[01:37:25] <LeelooMinai> Yes, I have soldered them. But in general I use reflow oven to assemble my designs.
[01:37:38] <zeeshan> is it like soldering stuff on xbox's
[01:37:41] <zeeshan> ive done that in the past
[01:37:49] <zeeshan> with a magnifying glass and a fine tip solder gun
[01:38:04] <zeeshan> it was a pain in the ass to not set stuff on fire :)
[01:38:10] <LeelooMinai> It's just a cheap toeaster oven with some extra insulation I stuffed in it + a controller I made.
[01:38:15] <zeeshan> ah
[01:38:48] <zeeshan> im sick of reading this data sheet!!!
[01:38:59] <zeeshan> so i talked to cpressed who uses a similar chip
[01:39:01] <LeelooMinai> So there's a thermocouple probe inside the oven and the controller monitors inside temperature and turns it on/off so it follows reflow curve recommended for particular solder paste type.
[01:39:02] <zeeshan> and he's running a bridge directly to it
[01:39:07] <zeeshan> without an external amplifier

[01:39:37] <zeeshan> LeelooMinai: that is cool
[01:39:52] <LeelooMinai> Well, as you know by now, it may work, just you may lose some resolution.
[01:40:01] -!- Loetmichel has quit [Ping timeout: 264 seconds]
[01:40:01] <zeeshan> LeelooMinai: not according to the datahseet
[01:40:08] <zeeshan> it's meant to work with low voltage singles
[01:40:10] <zeeshan> *signals
[01:40:23] <zeeshan> they say that if you actually give a signal close to the reference voltage, you get a lot more error
[01:40:49] <LeelooMinai> I don't know which one is that now, but as long as the signals are nicely within the input range, ok
[01:40:54] <zeeshan> its some fancy delta sigma adc
[01:41:23] -!- mozmck [mozmck!~moses@67.210.159.245] has joined #linuxcnc
[01:41:23] <zeeshan> By increasing the OSR, and thus reducing the output data rate, the noise performance of the ADC can be optimized.
[01:41:28] <zeeshan> osr = oversampling rate
[01:41:39] <zeeshan> n other words, the inputreferred noise drops when reducing the output data rate because more samples of the internal modulator are averaged to yield one conversion result. Increasing the gain also reduces the input-referred noise, which is particularly useful when measuring low-level signals
[01:41:57] <zeeshan> to a limit that is :P
[01:42:21] <LeelooMinai> Yes, ok, but that's the general idea. You still need to work out the real numbers
[01:42:31] <zeeshan> not really sure how to
[01:42:37] <LeelooMinai> Because "low" is a relative term
[01:42:38] <zeeshan> they give a bunch of formulas
[01:43:00] <LeelooMinai> Yes, you may need to spreadsheet them and plug in your scenario
[01:43:01] <zeeshan> "effective number of bits" = In (Full scale range / Vrms-noise) / IN(2)
[01:43:07] <zeeshan> fsr i know
[01:43:15] <zeeshan> v_rms noise they only list for 2.048, mine is 5v
[01:43:25] <zeeshan> no idea what in(2) is
[01:43:48] <zeeshan> i think if i can get this calculation down, itll give me more insight on how its going to perform
[01:44:17] <LeelooMinai> DOn't know - IN(2) looks like something you need to find there. IN means usually input
[01:44:31] <zeeshan> use your master electronics brain
[01:44:32] <zeeshan> http://www.ti.com/lit/ds/symlink/ads1220.pdf
[01:44:40] <zeeshan> page 15

[01:44:55] <LeelooMinai> What master electronics - I am a programmer and EE is my short-lived hobby:)
[01:45:08] <zeeshan> a lot more smarter than me in the subject :)
[01:45:18] <LeelooMinai> Let me see
[01:46:02] <LeelooMinai> That's ln(2) = natural log of 2 :)
[01:46:21] -!- swingley has quit [Ping timeout: 265 seconds]
[01:47:43] <zeeshan> LOL
[01:47:45] <zeeshan> hahahaha
[01:47:55] <zeeshan> i can't believe i didnt see that!
[01:48:02] <LeelooMinai> http://www.wolframalpha.com/input/?i=ln%282%29
[01:48:13] <zeeshan> oh i know ln by heart :)
[01:48:25] <zeeshan> actually idont, but i know the main values
[01:48:27] <zeeshan> like lne = 1
[01:48:33] <LeelooMinai> Yes, so it's a constant
[01:51:56] <zeeshan> okay so full scale range at gain of 128 is +/- 0.016V , so at 20S/s , they say 0.09 uVrms , ln(+/- 0.016/0.09)/ln(2)
[01:51:59] <zeeshan> numb er doesnt make sense :)

[01:54:35] <zeeshan> im used to using M and G
[01:54:35] <zeeshan> lol
[01:54:38] <zeeshan> not the other way around
[01:54:45] <zeeshan> well actually thats a lie, we use microstrains all the time
[01:54:54] <FinboySlick> Anyone here familiar with taking appart brushless fans like these?

[01:55:20] <zeeshan> ln(+/- 0.016/9e-8)/ln(2)
[01:55:21] <zeeshan> er
[01:56:21] <zeeshan> ln(+/- 0.016e-3/9e-8)/ln(2) = 7.5
[01:56:24] <zeeshan> eek!
[01:58:45] <zeeshan> okay i think i finally got it. fsr is actually 0.032. ln(0.032e-3/0.09e-6)/ln(2) = 8.5 bits
[01:58:47] <zeeshan> thats pretty bad!
[01:59:38] <zeeshan> that works out to a resolution of 5.7mV.
[01:59:56] <zeeshan> which means +/- 300lb
[01:59:59] <zeeshan> in practical numbers
[02:04:20] <zeeshan> grr this makes me so mad when people dont list units

[02:10:31] <zeeshan> 0.049 lb is the resolution
[02:10:33] <zeeshan> after all said and done
[02:10:44] <zeeshan> i was happy with +/- 25lb
[02:11:32] <LeelooMinai> Yes, well, there are also errors due to things that may happen in the "real world", due to PCB layput, cables, etc. - you will know those when you build and test

[02:19:33] <zeeshan> without disassembling it?
[02:19:34] <MacGalempsy_> no its under a cover
[02:19:40] <zeeshan> do you have a ground cable running to the motor?
[02:19:46] <MacGalempsy_> yah
[02:19:51] <zeeshan> okay dont take it apart for now
[02:19:55] <zeeshan> just disconnect it at the drive
[02:20:03] <zeeshan> and measure using the motor lead wires going to the drive

[02:53:56] <pcw_home> thats about it, 6i24 bitfiles allow 66 MHz PCI bus interface
[02:53:57] <Tom_itx> but the ucf for the 6i24 is in it
[02:54:06] <Tom_itx> same structure?
[02:54:18] -!- TTN [TTN!~TTN@unaffiliated/ttn] has joined #linuxcnc
[02:54:23] <pcw_home> No 6i24 bitfiles yeat
[02:54:29] <Tom_itx> so if i use the 6i24.ucf i need 66Mhz selected
[02:54:37] <Tom_itx> ?
[02:54:54] <pcw_home> yes but I dont think it will work yet
[02:55:03] <Tom_itx> oh that's a future option..
[02:55:04] <Tom_itx> :D
[02:55:27] <Tom_itx> i'll leave it all default for now on the jumpers, everything else looks default
[02:55:38] <pcw_home> it _might_ work...
[02:55:56] <Tom_itx> what might work?
[02:56:07] <pcw_home> a 6I24 bitfile
[02:56:24] <furrywolf> if I get a 7i76e, how much work is needed to set it up? is it a simple move wires over and reconfigure thing, or will I have to spend a month dicking around trying to compile software that won't compile, patching kernels, etc?
[02:56:33] <Tom_itx> how do i tell the difference? just the 6i24.ucf file?
[02:56:51] <pcw_home> I sort of learned from the 5i25/6i25 that there really was no need to have different bitfiles
[02:57:14] <pcw_home> a lot more work for a few usec faster
[02:57:42] <Tom_itx> ok, i'll just select the 6i24.ucf and pick a bit file that suits the configuraton

[02:58:58] <pcw_home> XXXXcard.vhd
[02:59:05] <Tom_itx> oh
[02:59:16] <Tom_itx> not a 6i24card.vhd?
[02:59:22] <pcw_home> no
[02:59:24] <Tom_itx> ok
[03:00:06] <pcw_home> you are building a 5i24 image basically (and all 5i24 bitfiles will work in the 6i24)

[04:16:51] <roycroft> have any of you tried making pcbs using toner transfer paper and a laminator?
[04:16:56] <roycroft> and if so, does it actually work?
[04:17:10] <Tom_itx> LeelooMinai, i've got 3 surface pro 3's with 8 on them
[04:17:11] <MacGalempsy_> just about done getting the last connections done.
[04:17:16] <Tom_itx> i don't care for it much
[04:17:22] <LeelooMinai> roycroft: Yes, I did a lot pcbs this way. Works for 2 layer pcbs with no too small traces
[04:17:32] <furrywolf> bbl, wolfy bedtime
[04:17:45] <roycroft> alignment must be tricky if you're doing 2 layer pcbs
[04:18:03] <roycroft> did you drill some through holes to help with alignment?
[04:18:24] <roycroft> and did you transfer the traces to both sides before etching?
[04:18:37] <LeelooMinai> Tom_itx: Win 8 is my main desktop - I cannot really say that I have any problems with it. As I said, I use it in Desktop mode, so it's like 7 with extras like better multi-monitor support and the History/Backup suport
[04:19:05] <LeelooMinai> roycroft: Yes, I drilled holes in the corners, or rather used some holes that pcb already needed to have

[04:19:49] <zeeshan> i have 4 monitors on this baby!
[04:19:50] <LeelooMinai> Always had
[04:19:56] <roycroft> both for different purposes
[04:20:14] <roycroft> but i got to thinking i might be able to make pcbs with that gear
[04:20:26] <zeeshan> LeelooMinai: surely there is a standard library
[04:20:29] <zeeshan> for terminal pads
[04:20:31] <zeeshan> this is pathetic.
[04:20:45] <LeelooMinai> Using Linux as a desktop - no thx. The GUI standards on Linux are 10 years behind other OSes
[04:21:03] <zeeshan> i personally live the gui in linux way better
[04:21:12] <zeeshan> but it's fall is no support for real software
[04:21:18] <zeeshan> you can run matlab and ansys on it
[04:21:19] <zeeshan> thats about it
[04:21:34] <LeelooMinai> zeeshan: It takes about 1 minute to make footprint in there - I could make it in 20 seconds probably:)
[04:21:46] <zeeshan> LeelooMinai: maybe im doing something wrong then?
[04:21:51] <zeeshan> i first make the component in component editor
[04:21:56] <zeeshan> then i open the pattern editor and make the pattern
[04:22:03] <zeeshan> then go to the schematic and realize i f'ed up
[04:22:05] <zeeshan> and do it again

[04:33:10] <roycroft> leelooninai: what kind of thermal transfer paper did you use for the pcbs?
[04:33:16] <roycroft> er, toner transfer paper
[04:33:17] <roycroft> sorry
[04:34:03] <LeelooMinai> roycroft: Laser printer glossy paper is good, but even better idea is using vinyl.
[04:34:33] <LeelooMinai> roycroft: Or even better idea just order PCBs from CHinese fabs.
[04:35:01] <roycroft> that takes too long
[04:35:25] <Jymmm> wait what?! laser cutter and vinyl... DONT DO IT!!!
[04:35:26] <LeelooMinai> Not if you pipeline the projects and do things in parallel. Planning:)
[04:35:49] <LeelooMinai> Jymmm: lol, what laser cutter? :)
[04:36:16] <roycroft> i prefer to keep my money as local as possible as well
[04:36:23] <Jymmm> No clue, I'm not really paying attention, just those two combined are BIG RED FLAGS
[04:36:49] <LeelooMinai> He asked about toner transfer. Using vinyl is better for that than paper.
[04:37:03] <roycroft> there is toner transfer paper that is designed for this kind of stuff
[04:37:13] <Jymmm> Ok, as long as a laser cutter is't involved.
[04:37:16] <roycroft> but i don't know how well it really works
[04:37:43] <roycroft> supposedly after you do the heat transfer of the toner a small amount of water will completely dissolve the paper
[04:38:07] <roycroft> the stuff is expensive though - about $2/sheet for a4 size
[04:38:15] <LeelooMinai> Yes, but why do that if with vinyl you don't have to dissolve anything
[04:38:39] <roycroft> i'm not sure how well vinyl will pass through my printer
[04:39:11] <LeelooMinai> It will pass fine - use thin Oracal they use to make signs. I did it many times
[04:39:28] <roycroft> i'm not dismissing your advice at all
[04:39:39] <roycroft> it's just a different unknown for me
[04:39:49] <LeelooMinai> http://imgur.com/sLaRJ
[04:40:14] <LeelooMinai> Just stick it on a paper, pass through, iron

[05:02:30] <zeeshan> to properly design circuits, and pcbs
[05:02:37] <zeeshan> you need to read a book, or take a class
[05:02:39] <zeeshan> so many little shits
[05:03:03] <zeeshan> The use of multiple vias in parallel lowers the overall inductance and is beneficial for connections to ground planes
[05:03:12] <zeeshan> im sure there is theory behind that :P
[05:05:32] -!- danylevskyi has quit [Quit: Leaving]
[05:06:04] <CaptHindsight> it gets trickier at high frequencies
[05:06:37] <CaptHindsight> but there's lots of well established techniques to follow
[05:07:18] <CaptHindsight> what you can get away with at low frequencies won't work well at high
[05:08:00] <CaptHindsight> multiple vias also increases the current capacity
[05:08:30] <CaptHindsight> filled vias also carry more current
[05:08:59] <CaptHindsight> solid cylinder vs a tube
[05:10:15] <CaptHindsight> there are hundreds of app notes on proper PCB layout
[05:10:31] <zeeshan> :P
[05:10:40] <zeeshan> its hard to randomly read
[05:10:43] <zeeshan> need an organized book
[05:10:59] <CaptHindsight> trace and space vs impedance
[05:11:18] <CaptHindsight> how to cross gaps in ground planes
[05:11:35] <CaptHindsight> layer spacing and copper thickness
[05:11:50] <CaptHindsight> dynamic impedance for multiple parallel signals
[05:12:11] <CaptHindsight> signals you don't want close to other signals
[05:12:32] <CaptHindsight> how to properly break out from BGA's
[05:13:11] <CaptHindsight> how to breakout from smt decoupling capacitors to vias and where to place them
[05:13:47] <LeelooMinai> zeeshan: I recommend this free app for PCB-related calculations:
http://www.saturnpcb.com/pcb_toolkit.htm
[05:14:13] <zeeshan> LeelooMinai: to use that software
[05:14:18] <zeeshan> you'd need to understand vias? :)
[05:14:39] <LeelooMinai> Vias is a plated hole - there - you understed most of it now:)
[05:14:40] <zeeshan> this stuff is a whole new world for me

[05:15:04] <CaptHindsight> and then there are IPC rules on trace and space, hole side vs pad size, hole location to traces etc etc
[05:15:13] <CaptHindsight> side/size
[05:15:48] <LeelooMinai> They are more like guidlines though
[05:15:54] <LeelooMinai> guidelines*
[05:16:16] <CaptHindsight> depends on the board house
[05:16:44] <CaptHindsight> if you start pushing the limits they will complain about yields
[05:17:23] <LeelooMinai> I don't think zeeshan will be pushing a lot of limits with his first pcb:)
[05:17:30] <zeeshan> haha
[05:17:32] -!- Tanz has quit [Client Quit]
[05:17:40] <zeeshan> i guarantee you it will set on fire
[05:17:41] <Cromaglious> sheeshz you'd think putting in a USB PCIe card wouldn't be that difficult
[05:17:56] <Cromaglious> USB 3 PCIe
[05:18:18] <CaptHindsight> looking back for really dense boards I'd use small board houses where the owner new the drilling machines so well he knew where it would have more or less repeatability
[05:18:25] <Cromaglious> ahh there's the light on my 1.5TG USB3 drive
[05:18:38] <Cromaglious> just waiting for it to show up in explorer now
[05:19:35] <LeelooMinai> zeeshan: My last design was 4 layer tiny board:
http://i.imgur.com/0a0OqH4.png
[05:19:43] <Cromaglious> hehe design 6 board onto one PCB then take a band saw and cut them apart?
[05:19:52] <zeeshan> LeelooMinai --- Level 99 achieved
[05:20:09] <zeeshan> that looks cool and fancy
[05:20:12] <LeelooMinai> FPGA + 1Gb ethernet
[05:20:22] -!- swingley has quit [Ping timeout: 240 seconds]
[05:20:24] <zeeshan> what was the point of it
[05:21:02] <LeelooMinai> It's for capturing trace data from ARM micros mostly and as a general gateway to 1G ethernet. Has also 1 Gb mDDR on it
[05:21:49] <Cromaglious> love the equal length traces going to the ethernet RJ45 port
[05:22:21] <CaptHindsight> zeeshan: layout your board and then post your files, we'll give you suggestions and point out any errors
[05:22:34] <LeelooMinai> But I don't really plan to go much more crazy than this... because I am just a hobbyist and big PCBs with more than 4 layers and some crazy specs, buried vias, etc. have still crazy prices. I don't want to pay $1k for pcb:)
[05:22:36] <zeeshan> im just laying out the schematic right now
[05:23:00] <zeeshan> LeelooMinai: how long did that take you to design
[05:23:07] <Cromaglious> My uncleeee worked at Texas Instruments back in the day... 10ns delay line... easy... just run a trace around the 10"x10" board
[05:23:19] <Cromaglious> err 100 or even 200ns
[05:23:44] <LeelooMinai> zeeshan: I am pretty easy going with my projects - do some work, then leave them alone, then go on some crazy binge and do a lot - cannot really tell:)
[05:24:33] <LeelooMinai> But if you want to do things the nice way, it takes time.
[05:24:46] <LeelooMinai> "never trust the aturouter" :)
[05:24:52] <zeeshan> hehe
[05:24:58] <zeeshan> did you work off datahseets
[05:25:02] <zeeshan> to figure out what components you needed?
[05:25:21] <LeelooMinai> As opposed to what? Talking to magical Elves? :)
[05:25:21] <CaptHindsight> http://imagebin.ca/v/1uJ6OZ4wgxeN don't worry, your board won't be anything like this :)
[05:25:57] <zeeshan> nah, like going back to the basics
[05:26:01] <CaptHindsight> you just need a low noise board with that 24b dac and clean power
[05:26:03] <zeeshan> and figure it out from electrical theory :P
[05:27:05] <LeelooMinai> zeeshan: Well, there's no lying - you need to know lot's of basics for the layout/design - so you can take into accout all details that normally you would not even be aware of.
[05:27:17] <zeeshan> exactly
[05:27:30] <zeeshan> its like mech eng design
[05:27:41] <LeelooMinai> But you may get away with it for some projects... But that's like blind chicken sometimes finding a grain:)
[05:27:42] <CaptHindsight> you'll learn by doing
[05:27:47] <zeeshan> theres so many failure modes
[05:28:42] <LeelooMinai> zeeshan: But to make you feel better, I am new to electronics relatively - maye 3 years and for the rest of time I was programming mostly.
[05:29:33] <Cromaglious> hehe I need a transmitter board.. 1.248Ghz oscillator with AM NTSC video injection and FM WB audio injection with 1watt out
[05:29:34] <zeeshan> hehe
[05:30:44] <zeeshan> https://www.dropbox.com/s/uu6uwjkm1zgdijo/circuit.pdf?dl=0
[05:30:48] <zeeshan> so this is pretty much what im trying to do
[05:30:54] <zeeshan> 2 thermo couples, 4 strain gages
[05:31:09] <CaptHindsight> http://www.mypage.tsn.cc/dakiller/dac1/dacb.png a beginners 24bit audio dac board
[05:31:37] <zeeshan> something will communicate over spi
[05:31:38] <zeeshan> with em
[05:31:49] <zeeshan> it'd be nice to do it directly from usb using that module LeelooMinai posted earlier

[05:39:19] <CaptHindsight> yes
[05:40:49] <zeeshan> hm
[05:41:01] <zeeshan> but i'd still need something else to interface it with the computer
[05:42:01] <CaptHindsight> is this separate from your mill?

[05:42:59] <zeeshan> arduino uno is like 30 bux
[05:43:04] <zeeshan> and will interface with this
[05:43:06] <zeeshan> for this application
[05:43:10] <LeelooMinai> zeeshan: That's one of my recent projects. I circled the IC that is I2C to USB bridge, same idea as with SPI, it's relatively simple to add it to your design as you can see.
http://i.imgur.com/95d7vn1.jpg
[05:43:47] <zeeshan> your board looks so nice
[05:43:48] <zeeshan> :D
[05:44:21] <zeeshan> http://ww1.microchip.com/downloads/en/DeviceDoc/22288A.pdf
[05:44:26] <zeeshan> i came across this while goolging
[05:45:15] <LeelooMinai> I also wrote an app that used that USB bridge to monitor the whole board:
http://i.imgur.com/Evamdnk.png
[05:45:44] <LeelooMinai> I would go with a bridge like that instead of external Arduino or other monstrosity.
[05:45:46] <renesis> leeloominai: ground loop, how considerate
[05:46:00] <zeeshan> yea it makes no sense to run an uno
[05:46:03] <zeeshan> just for spi communication
[05:46:11] <zeeshan> but it is 28$ :P
[05:46:44] <LeelooMinai> The extra usb connector + bridge IC will be probably like $5
[05:47:12] <LeelooMinai> renesis: You mean test point? Ground loops are bad:p
[05:47:28] <zeeshan> ive had enough of electronics for this week
[05:47:35] <zeeshan> its time to get back to mech eng!
[05:47:36] <zeeshan> :]
[05:47:42] <zeeshan> brain is too saturated
[05:48:03] <LeelooMinai> It's too late - now you will not be able to sleep until you complete your first pcb design.
[05:48:05] <renesis> leeloominai: technically its both! but yeah those things save me a lot of time, rarely there
[05:48:20] <zeeshan> hahaha
[05:48:51] <renesis> layout is def one of my favorite parts of the art
[05:49:24] <renesis> its like ceramics, functional art
[05:49:57] <LeelooMinai> What is ceramics though? :)
[05:50:13] <renesis> mud tech
[05:50:22] <LeelooMinai> Making pots and stuff?
[05:50:27] <renesis> yeah
[05:51:13] <renesis> ceramics will get shit from other art fields because a lot of it is functional
[05:51:37] <renesis> painters and sculptors talk shit
[05:51:43] <LeelooMinai> Lots of art is functional though
[05:51:56] <renesis> fine art typically isnt
[05:51:57] <LeelooMinai> Or at least can be
[05:52:14] <renesis> but yeah anyone who does technical stuff sees a lot of work as someones art
[05:53:18] <LeelooMinai> There's a saying "stat of the art" after all and people use it for many technical devices:)
[05:53:22] <LeelooMinai> state*
[05:53:25] <renesis> even if its as basic as, this is an expression of dudes mood at the office during this project
[05:54:10] <LeelooMinai> Also, arts is rather subjective - what is art for one person may be meaningless to another
[05:55:37] <renesis> you can definitely look at a PCB and connect it to cultures and eras
[05:56:34] <LeelooMinai> Yes, if it has a lot of hot glue on it and bode wires, it's from China:)
[05:56:41] <LeelooMinai> bodge*
[05:57:22] <LeelooMinai> j/k, Chine can design nice pcbs if they want
[06:00:41] <zeeshan> man tomorrow is going to be a long day
[06:00:53] <zeeshan> gotta prepare samples with known indentation depths
[06:01:02] <zeeshan> so gonna use a ball nose end mill to make some cuts
[06:01:19] <CaptHindsight> zeeshan: any masks yet?
[06:01:28] <zeeshan> then gotta laser cut a bunch of stuff for students
[06:01:30] <zeeshan> CaptHindsight: yes
[06:01:33] <zeeshan> i already tried it out
[06:01:34] <zeeshan> and failed

[06:01:40] <zeeshan> the dots are too big
[06:01:40] <CaptHindsight> \0/
[06:01:52] <zeeshan> i was thinking of using an air brush to spray it
[06:02:03] <CaptHindsight> to large a diameter?
[06:02:08] <zeeshan> nah to a fine mist
[06:02:11] <zeeshan> so the dots are small
[06:02:15] <zeeshan> but i dont know if that will work
[06:02:33] <CaptHindsight> the dots on the mask are too large a diameter?
[06:02:34] <zeeshan> im using our 3d microscope to do measurements right now
[06:02:41] <zeeshan> CaptHindsight: nah theyre small
[06:02:51] <zeeshan> but i dunno, when it goes through the mask
[06:02:55] <zeeshan> it spreads out a big making them huge
[06:03:59] <CaptHindsight> substrate, photopolymer, mask and then light source?
[06:04:27] <CaptHindsight> is the mask right on top of the polymer, in contact with it?
[06:04:40] <zeeshan> yep
[06:04:53] <CaptHindsight> whats the mask material?
[06:05:06] <zeeshan> .050 thick acrylic
[06:05:12] <zeeshan> i just cut it on the laser cutter

[06:07:07] <CaptHindsight> http://openlunchbox.com/smf/index.php?topic=40.msg94#msg94
[06:07:17] <CaptHindsight> 2nd link
[06:07:30] <CaptHindsight> yeah, you can air brush it
[06:07:44] <CaptHindsight> i think I kept the viscosity low
[06:07:53] <zeeshan> can i mix it with some solvent
[06:07:55] <zeeshan> to thin it even more?
[06:08:26] <CaptHindsight> it's 100% solids right now, 0 solvent
[06:08:30] <zeeshan> ah
[06:09:09] <CaptHindsight> if you introduce an organic solvent then you'll need to remove all the solvent before exposure/curing
[06:09:10] <zeeshan> ill go through these papers tomorrow

[06:11:12] <zeeshan> i think i have enough of this
[06:11:17] <zeeshan> to try to spray it with an air brush
[06:11:18] <zeeshan> and see what happens
[06:11:20] <zeeshan> if its clogging up
[06:11:30] <zeeshan> then ill look into a solvent
[06:11:31] <CaptHindsight> it won't clog
[06:12:03] <CaptHindsight> it won't dry until you expose it
[06:12:05] <zeeshan> okay then air brushing will definitely be the best technique!
[06:12:11] <zeeshan> will be a bit hard in the dark :)
[06:12:23] <CaptHindsight> not dark just not in the window
[06:12:33] <zeeshan> wait what?

[08:25:18] <renesis> they were way cheaper, i think they had a huge spool at the time
[08:25:43] <renesis> like, diodes per penny, not pennies per diode
[08:27:35] <archivist> look for 1n4148
[08:27:54] <archivist> which is near enough the same
[08:28:04] <renesis> well i think thats why 1n914 was cheap, obsoleted p/n
[08:28:42] <renesis> or maybe was in store price
[08:28:51] <archivist> they see $ when stuff becomes r@re
[08:29:07] <renesis> anyway 1n914 is better to use because porsche 914 are awesome
[08:29:11] <MacGalempsy_> renesis: you drive del puerto canyon yet:
[08:29:12] <MacGalempsy_> ?
[08:29:13] <renesis> thats my professional opinion
[08:29:23] <renesis> macgalempsy_: i might in a week
[08:29:44] <renesis> i shouldnt, its prob 3x the gas and time compared to cutting across on the 156
[08:30:18] <MacGalempsy_> its like disneyland, go once for the hell of it
[08:30:19] <renesis> but a friend passed away and am going to his life celebration party thing, and he would have been down with me driving that way
[08:30:28] <archivist> I wonder how many 914/4148s I have fitted in pcbs and soldered
[08:30:30] <renesis> i should take the 5, im going to valencia
[08:31:50] <renesis> and maybe itll rub out my front tires a bit
[08:32:21] <renesis> since i only drive highway, after alignment, my rears seem to be wearing same or faster than fronts
[08:32:34] <renesis> silly fwd car, youre not supposed to do that
[08:33:45] <renesis> everything even, like 15k on falkens and way more than half tread remaining (i get 30k out of them at best)
[08:33:52] <MacGalempsy_> two major obsticles. one is it is open range, if your car is too low it may be difficult to get over the cattle gaurds.
[08:34:10] <MacGalempsy_> two, it goes to one lane in many places, so beware for head ons
[08:34:18] <renesis> its not lowered, its bit low tho
[08:34:29] <renesis> right im used to that type of stuff
[08:35:10] <renesis> i dont drive faster than i can see, usually even on roads im pretty familiar with

[15:22:35] <Rab> Is that your gateway?
[15:23:20] <archivist> my public fixed ip is 81.149.189.98
[15:23:37] <Rab> Could it be that they're intentionally blocking port 80? Copyright claim by envious fellow archivists?
[15:23:49] <archivist> a plain ping should work to that ip
[15:24:04] <Rab> I can ping that.

[15:25:37] <_methods> yeah
[15:31:29] <miss0r|shop> swapper; yes, in my basement. I have a dedicated man-cave. I even placed network and power plugs in the sealing, so that when friends come over for some computer playing, I just set up a couple of tables, and connect them above ;)

[15:33:27] <Swapper> yea isnt that allways the case
[15:33:32] <Rab> archivist, you could contact accounts and politely ask if they will credit you for the present service outage...might see more action.
[15:33:47] <miss0r|shop> archivist: no, in the basement

[15:36:49] <miss0r|shop> I like the idea of a good LED projector; if you can make the room completely dark
[15:37:00] <Swapper> i have 1 space for a projector but it would be best if i could back project on a scrren
[15:37:10] <miss0r|shop> This one can do that
[15:37:26] <miss0r|shop> But I think they all can
[15:37:40] <Swapper> yea, its more of the distance to screen
[15:37:45] <Swapper> the throw distance
[15:37:46] <jdh> do you use a screen?
[15:38:18] <miss0r|shop> jdh: yes, a nice 109" with automatic retraction
[15:38:22] <miss0r|shop> Swapper:

[15:38:50] <miss0r|shop> Swapper: 0.7m for 60-100"
[15:38:59] <Swapper> bummer is we got loads of windows so light might be a problem
[15:39:10] <Swapper> you have all dark ?
[15:39:32] <miss0r|shop> Swapper: I have a few windows in there, but when I draw the blinds, it is all good

[17:13:50] <CaptHindsight> miss0r|shop: that Cre projector is a variation of the Epson LCD projectors. The LED life is 10-100x the life of lamps. It depends on how well they cool them.

[17:14:00] <SpeedEvil> Both a lathe and a mill are something I am also almost certain I don't have upstairs.

[21:34:58] <robinsz> it might well be doable under HAL

[23:56:35] <dirty_d> i doubt the tool edge is a perfect triangle point
[23:56:41] <dirty_d> it probably has a small radius to it
[23:56:49] <_methods> sure most threading tools do
[23:57:02] <_methods> go to the virtual sharp
[23:57:03] <dirty_d> so is the 0.240" cutting diameter the actual diameter, or the diameter a perfect 60deg triangle form would make?
[23:57:20] <_methods> is .240" your minor diameter?
[23:57:24] <Roguish> PCW: I have responded and added info to the forum post.
[23:57:28] <_methods> oh that is your tool form
[23:57:32] <dirty_d> no, the thread mill says 0.240" cutting diameter
[23:57:48] <_methods> i'd measure from centerline to check
[23:58:02] <_methods> but yes it should be .240" if that's what the datasheet says
[23:58:18] <dirty_d> 0.240" to the radius, if there is one?
[23:58:29] <dirty_d> because then you dont know what the pitch diamter of the cutter is
