(and in that region it's mostly double-exponential if we're talking about voltages rather than currents.) 17:40 < xentrac_> conveniently, that's also the region where it's dissipative. when you run it with a pure PWM waveform it's 100% efficient and perfectly linear until you get close to frequencies where the junction capacitance or the pins of the package or whatever start to resonate. microwave land. 17:41 < xentrac_> that is, if the input is on 37.2% of the time, the output will also be on 37.2% of the time, and off the rest of the time. when it's on there's no voltage, and when it's off there's no current, so in neither state does it dissipate energy 17:42 -!- jaboja [~jaboja@vps.jaboja.pl] has quit [Ping timeout: 276 seconds] 17:42 < xentrac_> a pure LC filter is also, in theory, 100% efficient, although of course in practice you are going to have several ohms or more of parasitic resistance in the inductor 17:42 < xentrac_> this may not actually be a desirable thing to do though 17:43 < xentrac_> with a diode laser, you also have wildly nonlinear (exponential) light output 17:43 < xentrac_> (with voltage. if you can control the current rather than the voltage you get quite good linearity because that very same exponential I-R characteristic gives you very nearly constant voltage over a wide range of currents.) 17:44 < nmz787_i> I don't want the laser to actually pulse though 17:44 < nmz787_i> hmm 17:44 < xentrac_> whereas if you just pulse the fuck out of the laser, it will also be on 37.2% of the time and provide 37.2% of its maximum output 17:44 < nmz787_i> yeah PWM controlled current was something I wanted originally, but wanted a good-enough workaround until I could implement something better 17:45 < nmz787_i> why do you say LC instead of RC? 17:45 < nmz787_i> just to reduce loss? 17:45 < xentrac_> right 17:45 < nmz787_i> ah, screw that, I can live with some heat in this room 17:45 < nmz787_i> and the laser seems plenty bright 17:45 < xentrac_> let's hope your resistor can live with the heat too; it's smaller than the room 17:45 < nmz787_i> putting the filter after the darlington shouldn't be too hard a rework 17:46 < nmz787_i> well on the microcontroller side that shouldn't have been a problem 17:46 < nmz787_i> on the output side, maybe more so 17:46 < xentrac_> exactly 17:47 < xentrac_> presumably you have a current-limiting resistor on the laser diode already? 17:48 < nmz787_i> nah, i took that off ;) 17:48 < xentrac_> haha 17:48 < xentrac_> careful 17:49 < nmz787_i> actually I don't think it was there, the one I'm thinking was a pullup 17:49 < xentrac_> ah 17:49 < nmz787_i> so the laser was dimly visible 17:49 < nmz787_i> for alignment 17:49 < xentrac_> nice 17:49 < nmz787_i> but that would screw with my photoresist 17:49 < xentrac_> the other thing is that it's common for LEDs, including laser diodes, to be able to handle more average power without damage when pulsed 17:49 < xentrac_> I'm not sure why that happens but it's a significant effect 17:49 < nmz787_i> i think its hea 17:49 < nmz787_i> heat 17:50 < xentrac_> well of coures, sure, but why? 17:50 < nmz787_i> this is just a cheap 405nm laser, probably similar to a pointer 17:50 < nmz787_i> oh, something about its resistance coefficient or something 17:50 < xentrac_> I suspect it might have to do with the time required to go into localized thermal runaway, where the negative temperature coefficient of resistance of semiconductors concentrates the current at one spot 17:51 < nmz787_i> yeah that coefficient 17:51 < xentrac_> which is usually the thing that limits the current of a semiconductor iode 17:51 < xentrac_> diode 17:52 < xentrac_> anyway so those are some reasons that people usually drive LEDs with PWM directly 17:52 < xentrac_> instead of using constant-voltage variable-current power-supply circuits, which are also a thing that exists 17:52 < nmz787_i> yeah 17:53 < nmz787_i> I was looking at the one Dave Jones was documenting designing 17:53 < nmz787_i> but then got lazy, tried smooth-PWMing an LM317 adjust pin, but that wouldn't go below 1.25V (forgot that key point) and I guess the laser was still turning on at that point 17:54 < xentrac_> heh 17:54 < xentrac_> why are you averse to letting the laser pulse? 17:54 < nmz787_i> i'm exposing photoresist 17:54 < nmz787_i> assumption is i'd see dots 17:54 < xentrac_> oh, if the waveform is slow enough, sure 17:54 < xentrac_> but how many pixels per second are you doing? 17:55 < nmz787_i> uh 17:55 < nmz787_i> idk 17:55 < xentrac_> I mean presumably you can defocus the beam so that the spot is a little smaller than a pixel and then pulse the PWM an order of magnitude faster than the pixel rate 17:55 < xentrac_> and then you won't have that problem 17:55 < nmz787_i> yeah, I figured I'd just elimate it altogether and not have to do that calculation 17:55 < xentrac_> or two orders of magnitude if you don't want to worry about the defocusing 17:56 < xentrac_> presumably you have some order of magnitude in mind though? I mean it's probably more than a pixel per day 17:56 < xentrac_> and probably less than a gigapixel per second 17:57 < nmz787_i> well since this is targetted for microfluidics, I just really wanted to avoid any noise, since I presumed i'd have a lot of other sources of fabrication woes 17:57 < xentrac_> why do you want states in between "on" and "off"? 17:57 < nmz787_i> there's this http://diyhpl.us/laser_etcher/laser_etcher/#index7h1 17:57 < nmz787_i> xentrac_: want to be able to control dosage of power 17:57 < nmz787_i> watts/sqaure 17:58 -!- drewbot_ [~cinch@ec2-54-87-66-46.compute-1.amazonaws.com] has quit [Remote host closed the connection] 17:58 < xentrac_> you could probably do that by varying the pixel rate 17:58 -!- drewbot [~cinch@ec2-54-162-23-178.compute-1.amazonaws.com] has joined ##hplusroadmap 17:59 < xentrac_> 15 minutes for 31 megapixels? that would be about 35000 pixels per second 17:59 < nmz787_i> if the only upside is less burst power, it's not as interesting as being sure pulsation at some level isn't the culprit of some nanoscale feature noise 17:59 < xentrac_> or almost 30 microseconds per pixel 18:00 < nmz787_i> those calculations were desired I think 18:00 < nmz787_i> i'm not sure what I'm actually using 18:00 < xentrac_> well, but maybe you could just like step the motor faster if you want less exposure, instead of trying to modulate the beam 18:00 < nmz787_i> I think it's ~50 steps per mm, with x8 microstepping turned on 18:00 < nmz787_i> and I last used a feedrate of 380 18:01 < xentrac_> so it only spends 25 microseconds per pixel, say 18:01 < xentrac_> 380 steps per second? 18:01 < nmz787_i> I am guessing it is mm/min 18:01 < nmz787_i> checking 18:01 < xentrac_> ah, in the G-code 18:01 < nmz787_i> yeah 18:01 < xentrac_> I forget 18:01 < nmz787_i> yeah seems mm/min 18:02 < xentrac_> do you understand what I'm saying about just varying the feedrate instead of using PWM? Then you don't have to worry at all about PWM 18:02 < nmz787_i> yeah 18:02 < nmz787_i> but the motor is pulsed too 18:02 < nmz787_i> so it could end up being an error source that needs eliminated 18:02 < xentrac_> yes, but that's true whether or not you use PWM on the beam 18:02 < xentrac_> that's about 6000 pixels per second 18:02 < xentrac_> if they're micron pixels 18:03 < xentrac_> (do you have the beam focused down to a micron? that's damned impressive) 18:03 < nmz787_i> well if its 50 steps /mm then they're 20 micron steps 18:03 < nmz787_i> or 20/8 if the microstepping counts 18:03 < xentrac_> oh, I guess so 18:03 < nmz787_i> (not sure if its already factored into the 50) 18:04 < xentrac_> a 20-micron spot seems pretty plausible, 2.5 is going to be tough 18:04 < xentrac_> are you taking advantage of nonlinear photoresist response to sharpen the edges? 18:05 < nmz787_i> it's from ebay, with chinese-english instructions in the ebay ad description. 18:05 < nmz787_i> so who knows 18:05 < xentrac_> otherwise the blurriness of a 2.5-micron spot at 400nm wavelength is going to be really bad even in the best case 18:05 < xentrac_> I guess you'll find out! 18:05 < nmz787_i> I have a bluray laser sled that I'll upgrade to soon enough 18:05 < xentrac_> okay, I have to head home 18:05 < xentrac_> good luck! 18:05 < nmz787_i> it has a feedback diode in it for monitoring the brightness 18:05 < nmz787_i> bye! 18:08 -!- nildicit_ [~nildicit@unaffiliated/nildicit] has quit [Ping timeout: 240 seconds] 18:10 -!- sandeepkr__ [~sandeep@111.235.64.4] has joined ##hplusroadmap 18:14 -!- sandeepkr_ [~sandeep@111.235.64.4] has quit [Ping timeout: 260 seconds] 18:15 -!- nildicit [~nildicit@gateway/vpn/privateinternetaccess/nildicit] has joined ##hplusroadmap 18:19 -!- sandeepkr_ [~sandeep@111.235.64.4] has joined ##hplusroadmap 18:20 -!- sandeepkr__ [~sandeep@111.235.64.4] has quit [Ping timeout: 246 seconds] 18:24 -!- jaboja [~jaboja@vps.jaboja.pl] has joined ##hplusroadmap 18:39 -!- 7F1AA2CI0 [~en14c@189.114.254.36] has quit [Quit: Leaving] 18:53 -!- sandeepkr_ [~sandeep@111.235.64.4] has quit [Quit: Leaving] 18:53 -!- sandeepkr [~sandeep@111.235.64.4] has joined ##hplusroadmap 18:57 -!- yashgaroth [~yashgarot@2602:306:35fa:d500:f5e0:f867:a11d:8d52] has joined ##hplusroadmap 19:25 -!- juul [~juul@juul.io] has quit [Quit: WeeChat 0.4.2] 19:54 -!- _Sol_ [~Sol@c-69-141-24-242.hsd1.nj.comcast.net] has joined ##hplusroadmap 20:09 -!- jaboja [~jaboja@vps.jaboja.pl] has quit [Ping timeout: 244 seconds] 20:10 -!- Gurkenglas__ [Gurkenglas@dslb-178-000-182-226.178.000.pools.vodafone-ip.de] has quit [Ping timeout: 244 seconds] 20:25 < nmz787_i> you guys are borin 20:51 -!- ArturSha1 [~ArturShai@195.114.240.87] has joined ##hplusroadmap 21:03 < kanzure> true. i am 100% nyc now. have the look down, the meetings and the street grid figured out. 21:20 -!- Jenda`_ is now known as Jenda` 22:12 -!- abetusk [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has quit [Ping timeout: 276 seconds] 22:25 -!- abetusk [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has joined ##hplusroadmap 22:25 -!- abetusk is now known as Guest55554 22:37 -!- Orpheon_ [~Orpheon@196.100.62.81.dynamic.wline.res.cust.swisscom.ch] has quit [Read error: Connection reset by peer] 22:42 -!- Guest55554 [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has quit [Ping timeout: 276 seconds] 22:54 -!- Guest55554 [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has joined ##hplusroadmap 22:57 -!- yashgaroth [~yashgarot@2602:306:35fa:d500:f5e0:f867:a11d:8d52] has quit [Quit: Leaving] 23:03 -!- jtimon [~quassel@65.28.134.37.dynamic.jazztel.es] has quit [Ping timeout: 260 seconds] 23:28 -!- juul [~juul@juul.io] has joined ##hplusroadmap 23:46 -!- Guest55554 [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has quit [Ping timeout: 260 seconds] 23:50 -!- sandeepkr [~sandeep@111.235.64.4] has quit [Ping timeout: 276 seconds] 23:57 -!- Quashie [~boingredd@CPEbc4dfb5bf733-CMbc4dfb5bf730.cpe.net.cable.rogers.com] has joined ##hplusroadmap 23:57 < nmz787_i> papa needs a new (to me) fume hood 23:59 -!- Guest55554 [~abram@c-98-216-104-129.hsd1.ma.comcast.net] has joined ##hplusroadmap --- Log closed Wed May 04 00:00:05 2016
