10:12 < chris_99> nope 10:12 < chris_99> just beer :) 10:13 < archels> the easiest approach would be to attach the float to a potentiometer 10:13 < chris_99> ThomasEgi mentioned that 10:13 < chris_99> there isn't enough force from the hydrometer 10:13 < chris_99> for that to work though 10:15 < archels> well, you have to make a lever. If the force is small, make the pot only rotate a few degrees 10:15 < archels> and/or get a better pot 10:16 < archels> otherwise, you can make a simple linear optical encoder from an old inkjet printer 10:16 < chris_99> that wouldn't be as precise though as using an imaging sensor 10:17 < archels> well, with an image sensor you need to keep stuff aligned pretty well for it to stay in focus 10:17 < archels> and you need an appropriate light source and optics 10:19 < chris_99> true, i don't think i need any fancy optics though, i was planning on aligning the top of the hydrometer in a tube with the LED pushed up to the sensor 10:20 < nmz787> chris_99: this just uses 2 LEDs http://moab.eecs.wsu.edu/~pedrow/classes/ee415/Fall_2005/Refereed%20Papers/paper1_garnet.pdf 10:20 < nmz787> ahh that's liquid level though, not a stick's level 10:21 < nmz787> have you considered buying a magnet strip and using a hall effect sensor?

10:25 < nmz787> and just count ticks like the magnet strip? 10:25 < ThomasEgi> chris_99, i wouldnt say that it's not precise enough 10:25 < ThomasEgi> optical encoding can get you μm precision 10:25 < chris_99> well you'd have to make them tiny for it to work 10:25 < chris_99> which would need an image sensor of v. high dpi 10:26 < ThomasEgi> nope. no need for a high dpi sensor :) 10:26 < ThomasEgi> you just have to add a mask in front of it 10:26 < chris_99> huh? 10:26 < chris_99> not heard of that, how's that work 10:26 < ThomasEgi> so you have like.. 2 line patterns 10:26 < ThomasEgi> which shift over each other 10:26 < chris_99> hmm interesting 10:26 < ThomasEgi> resulting in a triangular brightness change 10:27 < ThomasEgi> it's a relative messurement. very precise tho. you need ocassional marks for absolute positioning. 10:27 < nmz787> I think he means something like this, with one or two pixels instead of a camera http://en.wikipedia.org/wiki/Structured-light_3D_scanner 10:27 < ThomasEgi> but those can easily be done with like optical endstops or so 10:27 < ThomasEgi> nmz787, nope. 10:27 < nmz787> and instead of the pattern generated by a projector, it's just printed on the hydrometer?

10:32 < nmz787> that seems like it would be cheap, and you'd need less CCD pixels 10:33 < nmz787> you might also be able to do it through the glass 10:33 < chris_99> a couple of reasons, not esp. accurate for beer apparently, and also in-place ones are expensive 10:33 < ThomasEgi> i can't really find the name for it. i'd have to work through my university stuff to find it. 10:33 < chris_99> no worries 10:33 < ThomasEgi> but.. once more. i highly recommend to go with that coil approaches , messuring AC voltage 10:34 < nmz787> i'd just place a red laser on the opposite side of the glass carboy, across from the CCD, then refraction should move the spot up or down the CCD 10:34 < nmz787> i think that might work 10:34 < ThomasEgi> it's rather robust. not depending on optics, so it works in a dirty and wet environment. relatively simple and cheap 10:35 < chris_99> just thinking if i did that ThomasEgi i could use those tiny sealed inductors 10:35 < chris_99> couldnt i 10:36 < ThomasEgi> ... you could if you change the geometric arrangement 10:36 < ThomasEgi> i'd pretty much have one coil inside a set of other coils. 10:36 < ThomasEgi> arranged on one axis 10:36 < chris_99> i was thinking you meant lots of coils on the hydrometer and then a hall effect on the float 10:36 < ThomasEgi> nope. 10:37 < ThomasEgi> you basically wind a thin wire around the hydrometer. and turn it into a coil this way 10:37 < ThomasEgi> then you put a tube, wind wire around it in like 8 sections (they may overlap, just make sure each has the same winding count). 10:37 < ThomasEgi> and you put that over the dryrometer, mounted to the float. 10:39 < ThomasEgi> then you connect a capacitor in series with the hydrometer coil, feed a rectangular signal to it (from a microcontroller) that matches the resonance frequency of the LC circuit 10:39 < ThomasEgi> the rest is just adding a few diodes to rectify each of the float-coils outputs , buffer that with a small capacitor, maybe voltage divide down to to a save microcontroller-voltage level. and ADC your results 10:40 < ThomasEgi> will result in like 8 adc results, building the weighted average you can easily calculate the position of your float. 10:40 < chris_99> very interesting, so the hydrometer becomes an electromagnet right and you're sensing it's position using these 8 coils around the cylinder? 10:40 < ThomasEgi> exactly 10:41 < ThomasEgi> and since it is an alternating magnetic field. you can pick the signal up with simple and cheap coils, instead of magnetometers 10:41 < chris_99> and it'll resonate perfectly as it where if its exactly aligned to the coils, and when it moves it'll generate a different signal 10:41 < ThomasEgi> it's dirt cheap, pretty robust, reasonably simple/difficult. and with a bit of tuning i'm pretty sure it'll be accurate enough,too 10:42 < ThomasEgi> the receiver coils won't resonate 10:42 < ThomasEgi> they just pick up the field change and convert it into a voltage for you. 10:42 < chris_99> ok that makes sense 10:43 < chris_99> so it's sort of calculating the difference from a perfect waveform right? 10:43 < ThomasEgi> nope. 10:43 < ThomasEgi> the waveform gets rectified. 10:43 < ThomasEgi> so the result is like a signle analog value for each pickup coil 10:43 < chris_99> oh right 10:44 < ThomasEgi> it'll probably look a bit like a gauss-curve or so , if you draw it with the 8 points 10:44 < ThomasEgi> all you have to do is find the peak-point of that. 10:44 < ThomasEgi> but that's a mathematically simple operation 10:44 < ThomasEgi> even if you have only 8 points. the weighted mean will turn out nicely 10:45 < ThomasEgi> in worst case. you'll have to apply some linearisation-correction at the end of it. but that's easy to do,too. 10:46 < ThomasEgi> the only thing that mihgt be a bit tricky without a scope is to get the resonance frequency set right. but, with some tricks, that's not half as difficult 10:47 < chris_99> i do have a scope actually 10:47 < ThomasEgi> even better then. 10:48 < ThomasEgi> but in yuor case. you could controll the frequency by the μC. and just ramp throught the frequency range once. messuring the voltages on the pickup coils. and then use the frequency where it maxed 10:48 < ThomasEgi> as long as you protect the microcontrollers ADC pins from overvoltage, there's very little that could go wrong 10:49 < ThomasEgi> wrong as is, ruining your day. 10:49 < chris_99> mm sounds a very clever idea 10:50 < ThomasEgi> yeah. the only thing that might be even easier. would be to use a triangulation sensor. given you can find one for the distance you want. 10:50 < ThomasEgi> but then, it's optical again and i have no idea how well that'll work out if there's foam and stuff around 10:50 < ThomasEgi> i'd go with the coils 11:02 < chris_99> this site's got some cool stuff http://www.disensors.com/products.aspx?id=21 11:02 < chris_99> i bet they're not cheap though 11:17 -!- chris_99 [~chris_99@unaffiliated/chris-99/x-3062929] has quit [Remote host closed the connection] 11:23 -!- panax [~panax@68.200.160.182] has joined ##hplusroadmap 11:25 -!- xx is now known as Bearfore1 11:25 -!- Bearfore1 is now known as bearforce1 11:25 -!- lichen_ [~lichen@c-24-21-206-64.hsd1.or.comcast.net] has joined ##hplusroadmap 11:28 -!- lichen [~lichen@c-24-21-206-64.hsd1.or.comcast.net] has quit [Ping timeout: 255 seconds] 11:28 -!- panax [~panax@68.200.160.182] has quit [Ping timeout: 276 seconds] 11:30 -!- lichen_ [~lichen@c-24-21-206-64.hsd1.or.comcast.net] has quit [Ping timeout: 255 seconds] 11:30 -!- lichen [~lichen@c-24-21-206-64.hsd1.or.comcast.net] has joined ##hplusroadmap 11:32 -!- chris_99 [~chris_99@unaffiliated/chris-99/x-3062929] has joined ##hplusroadmap 11:44 -!- panax [~panax@68.200.160.182] has joined ##hplusroadmap 11:52 -!- panax [~panax@68.200.160.182] has quit [Ping timeout: 245 seconds] 11:53 -!- chris_99 [~chris_99@unaffiliated/chris-99/x-3062929] has quit [Remote host closed the connection] 11:55 -!- chris_99 [~chris_99@unaffiliated/chris-99/x-3062929] has joined ##hplusroadmap 11:59 -!- eudoxia [~eudoxia@r186-53-135-240.dialup.adsl.anteldata.net.uy] has quit [Quit: Leaving] 12:00 -!- hifrog [~green@p5B16E9CA.dip.t-dialin.net] has joined ##hplusroadmap 12:02 -!- augur [~augur@208.58.5.87] has quit [Remote host closed the connection] 12:02 < hifrog> ~ 12:03 < hifrog> paperbot help 12:03 < hifrog> !paperbot 12:03 < hifrog> no?... hmm 12:04 < chris_99> you do paperbot: url i think 12:04 < hifrog> paperbot: https://www.sciencemag.org/content/339/6118/440 12:04 < paperbot> SSLError: [Errno 1] _ssl.c:504: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (file "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 632, in send) 12:05 < kanzure> https is not supported 12:05 < hifrog> paperbot: 10.1126/science.1226018 12:05 < hifrog> oh hehe 12:05 < hifrog> paperbot: http://www.sciencemag.org/content/339/6118/440 12:05 < paperbot> http://diyhpl.us/~bryan/papers2/paperbot/To%20Favor%20Survival%20Under%20Food%20Shortage%2C%20the%20Brain%20Disables%20Costly%20Memory.pdf 12:05 < kanzure> .botsnack 3 12:05 < yoleaux> :D 12:05 < kanzure> (positive reinforcement) 12:05 < hifrog> <3 12:05 < kanzure> nmz787: the backlash in the home dialysis thread is hilarious 12:09 < nmz787> kanzure: weird for sure 12:09 < nmz787> http://www.frontiersin.org/Microbiotechnology,_Ecotoxicology_and_Bioremediation/10.3389/fmicb.2013.00005/full 12:09 < nmz787> Preparing synthetic biology for the world 12:09 < nmz787> Gerd H.

< ThomasEgi> the big capacitors (0.1uF isn't really big) are stored with the terminals shorted , so they don't accidently charge up from some random source. 20:25 < nmz787> col 20:25 < nmz787> cool

while. but you can check with a voltmeter. 20:28 < ThomasEgi> given a regular 0.25W resistor 20:32 < ThomasEgi> and there goes my connection.. i guess 20:32 < ThomasEgi> and.. i'm back .. i guess
