| 00:33 < kevtris> sounds like pork rinds | |
| 00:34 < kevtris> that's what that is, deep fried fat | |

| 00:36 < password2_> to be clear , its just deep fried in itself , if i understand craklings correctly its deepfried in oil | |
| 00:36 < sammyb> its great password2_ they don't always get it right but when they do the icecream softens inside the batter and forms an almost cake-like boundary between the two | |

| 00:39 < leachim6> I want to make a fan for my desk that's really quiet, so I was thinking of getting some 120mm ultra quiet case fans (2x) and mount them to a sheet of Lexan with some kind of voltage controller to have some quiet airflow to my face, and also it'll look cool on my desk | |

| 00:40 < password2_> leachim6, get a current regulator and a big cap | |
| 00:40 < Casper> leachim6: you need 12V for fans normally | |
| 00:40 < password2_> their easier to control with current | |
| 00:40 < leachim6> well then I'll need a 12v adapter that's not huge | |
| 00:40 < leachim6> a repurposed PSU is out of the question | |
| 00:40 < leachim6> it's gotta fit on the back of the sheet of lexan with either screws or epoxy | |
| 00:41 < Casper> and if you can, get 4 pins fans, then just make a PWM to control them on that 4th wire | |

| 00:41 < password2_> i cant put it in my pc because of noise | |
| 00:41 < leachim6> Casper: that's what I was thinking, because I don't need a lot of logic like real PC case fans, just a consistent speed | |
| 00:41 < Casper> and if you want quiet, the bigger the better | |
| 00:41 < leachim6> 1.1A is crazy current for a fan | |
| 00:41 < password2_> but if you limit its current then you get a nice breeze with very little noise | |

| 01:30 < R0b0t1> o rite | |
| 01:30 < R0b0t1> my bad | |
| 01:30 < larrycv> it is a charger from canon dslr that cost $2000 back in the day, so it shouldny be complete crap | |
| 01:30 < theBear> larrycv, maybe use the battery for a little bit, observe if it uses a normal or excessive (compared to when it was healthy and new) % of capacity while doing it, then give it another charge, but if it finishes low again, try several "topup" charges, even if you gotta do a few mins at a time (for example if the charger waits a few mins then does its fullness check and cuts off) | |
| 01:30 < Gary_jose> amds tend to run a bit hotter | |
| 01:30 < Casper> but point is... a 150$ cpu come with a 150$ gpu, free | |
| 01:31 < theBear> crapness is kinda irrelevant in cases like this, what works with healthy batteries is very different to dead and less than healthy ones | |
| 01:31 < Casper> and have the performance of a 200-250$ intel cpu... | |
| 01:31 < theBear> also if it's a fast charger but has a slow setting, that should help | |
| 01:31 < Gary_jose> also amd cpu;s and chipsets have issues with linux, the drivers sometimes don;t work properly | |

| 01:33 < larrycv> it has no way to set charging speed. its output is 8.4V @ 1.2A | |
| 01:33 < Gary_jose> one more thing is intel is a billion dollar company , much bigger than amd. so they can afford a lot of research and developement work, and the end result is that customer gets a more refined product | |

| 01:47 < theBear> and if the camera agrees, i'd be tempted to say they are charging fully, and ask what symptoms you are actually trying to deal with | |
| 01:47 < SuperBrainAK> hey does anyone know of a fairly simple circuit that could give me a voltage that is a fixed amount lower than a buck converters output? | |
| 01:47 -!- RoBo_V1 is now known as RoBo_V | |

| 01:48 < larrycv> here is the battery | |

| 01:48 < larrycv> http://www.bhphotovideo.com/c/product/327022-REG/Canon_9200A001_BP_511A_Lithium_Ion_Battery_7_4v.html | |
| 01:48 < Casper> ... specially on cracked licence | |
| 01:48 < Casper> larrycv: it is also possible that the battery never get fully charged | |
| 01:49 < theBear> but USUALLY it is less wrong to modify the buck converter (often a tweak of the voltage feedback divider network hanging off the output pin and feeding back to the control section) | |
| 01:49 < Casper> to extend it's life | |
| 01:49 < Casper> you sacrifice some capacity for more cycles and more years | |
| 01:49 < SuperBrainAK> problem is i will be sinking from the buck converter to the other rail, and 78xx's and zeners or other regs only source power | |
| 01:49 < larrycv> it is 5 years old btw. and runtime sucks compared to when it was new | |

| 01:51 < SuperBrainAK> :P | |

| 01:52 -!- tristanseifert [~tristanse@12.207.21.2] has joined ##electronics | |
| 01:52 < theBear> SuperBrainAK, generally bucks can only source too | |
| 01:53 < SuperBrainAK> so maybe i need about a -5v rail then a negative linear reg with its input on the -5v and the output the "middle" rail and the 79xx's "ground" on the buck converter? | |
| 01:53 < theBear> but either way it doesn't matter, a diode/zener in series will just drop voltage, no matter what | |
| 01:53 < theBear> so long as the voltage doesn't flip in polarity | |
| 01:53 < theBear> think of a series diode as a set-voltage series resistor | |

| 01:54 < Casper> no... | |
| 01:54 < Casper> yes | |
| 01:54 < SuperBrainAK> that will not allow me to have a current flow from the buck converter to the middle rail | |
| 01:55 < SuperBrainAK> basically i want an adjustable ground rail | |
| 01:55 < larrycv> could I just put plain li-ion cells in that case, or does the fact that there are two of them complicate matters? new battery is $50, which is a lot for just two li-ion cells | |
| 01:55 < SuperBrainAK> that is a fixed voltage lower than my buck converter | |
| 01:55 < theBear> a 5year old battery that has had even semi regular use, specially one that sat and went flat like i gather this one did recently, is never gonna have a great capacity by this stage, but that one, particularly if the cam battmeter agrees, does seem to be in "fine" health, even if the capacity is markedly lower than new | |

| 01:57 < Casper> way cheaper | |
| 01:57 < theBear> well diode/zener/adjustable-zener, it's not really a shunt reg unless you feeding it via a shunt | |

| 01:58 < SuperBrainAK> ok | |

| 02:00 < theBear> and also that apart from being referenced to "ground" all yer linear regs and similar setups ARE an "adjustable zener/diode" just like this ' | |
| 02:00 < SuperBrainAK> so if i have a zener (say 3v) pointing towards my middle rail then a resistor to the main input rail of the buck how can that be always 3v less than my buck converter? | |
| 02:00 < theBear> no resistor | |
| 02:00 < SuperBrainAK> that will only be 3v above ground | |
| 02:01 < theBear> you might need SOME resistor if the load hanging off the -3v point is ridiculously low current | |

| 02:03 < theBear> umm, i'm a little lost in which rail is which and what the buck is doing, but zener from memory work "backwards" to real diodes which you would point from positive to negative in this case, so err, yeah | |

| 03:03 < SuperBrainAK> lol | |
| 03:03 < metacollin> Johnsen: dunno if you're around mate, but that LTspice simulation you couldn't get to resolve, try putting 1000K or 100K parallel resistance in the properties (not as a seperate resistor) of every capacitor. Or whatever, as much leakage as you can tolerate. That often will make transient analyses that aren't resolving resolve. | |
| 03:04 < theBear> no, the first one should be right, under 1/4w | |
| 03:04 < SuperBrainAK> ill keep playing | |
| 03:05 < theBear> metacollin, Johnsen, first it can be worth looking for similar but lesser problems, like err, been a while, i'm thinking something like 1meg/ANY resistor off something, opamp inputs or feedbackless comparator outputs or something? meh, that wasn't as helpful as i intended | |
| 03:06 < theBear> weather holding, the time is right, to the shops ! | |
| 03:06 < SuperBrainAK> i know i will need some sort of preamp for the main transistor because my 5k trim pot going to the base of the main transistor could not handle the current | |

| 03:06 < theBear> yeah, even a transistor-feed is a lot for a trimpot or even regular pot sometimes, to handle | |
| 03:07 < password2> i like circuits that leverage parasitic effects | |
| 03:07 < theBear> if it's not superbig there are some nice darlingtons commonly available | |
| 03:07 < _abc_> metacollin: that is not a good plan imho, but you can use a different solver method or add 'start voltages from 0' and that usually helps | |

| 03:09 < theBear> nice.. 2 crates of relays and you could have a real handy variable load going on | |
| 03:09 < _abc_> metacollin: I see. Another thing I tried in the past was to set the min time step forcibly smaller than calculated automatically. | |
| 03:09 < theBear> or a massively high powerhandling d-a | |

| 03:10 < metacollin> I should look at the settings more heh. | |
| 03:10 < _abc_> theBear: 10 relays = 1024 resolution, 0.1% | |

| 03:11 < Brisance> the one pictured is 100W 1R3 | |
| 03:11 < metacollin> Plus, when something doesn't resolve, it might be because there is something impossible in the sim. I.e., superconducting capacitors (the default, caps with no ESR), or caps, or caps with 0 leakage. Like, 1M resistors in parallel is more realistic than capacitors with no leakage at all. But perhaps go higher, something close to the real leakage of the cap in question. At least this has worked for me before, but who know | |
| 03:11 < Brisance> with a screw settable wiper as well | |
| 03:12 < Brisance> that is you have to unscrew a screw, set it in place and screw it tight | |
| 03:12 < genewitch> ^ that's what thebear said | |
| 03:12 < metacollin> lol whoops, um. ignore the 'or caps' with nothing else | |

| 03:12 < genewitch> both of those things | |
| 03:12 < theBear> mmm, and don't forget that superconductor wires/conductors would mess up some things | |
| 03:12 < metacollin> yyeah | |
| 03:13 < metacollin> good to add parasitics everywhere | |
| 03:13 < _abc_> theBear: ^ that's somewhere near you, more or less. | |
| 03:13 < theBear> just a hassle adding lots, specially when you first decide to go from none to doing it like that | |
| 03:13 < theBear> mmm, i walked past the place | |
| 03:13 < theBear> not in this state, but still | |
| 03:14 * _abc_ notes that switch has 8 contacts but that should also account for 1 reverse speed at least. | |
| 03:14 < theBear> seriously this time, i'm goin to the shops | |
| 03:14 < Brisance> but... I AM GONNA DO THE RELAY DAC | |
| 03:14 < _abc_> do it | |
| 03:14 < _abc_> Also remember when you switch state it will briefly cut out. | |
| 03:14 < _abc_> Depending on what the load is that can work out badly. | |
| 03:15 < Brisance> maybe even make it usable as a digital variable load | |
| 03:15 < _abc_> Just pay attention to the break before make character of most relays... | |
| 03:16 < Brisance> maybe switch to a temporary load while switching? | |

| 03:32 < metacollin> Brisance: inductance is really easy to do really accurately. You simply use a comparator that puts out a digital signal based on a resonant LC tank circuit. Then, you can put an inductor you want to measure in series with the reference inductor (which is tanked with the cap), and just do some math on the frequency out | |

| 03:36 < metacollin> and you can even replace the reference cap and inductor with your own higher accuracy ones later. I have a crap one, it has a calibration function which measures the lead inductance and subtracts it. It works quite well considering it was $17. http://www.ebay.com/itm/L-C-F-Digital-led-Inductance-Capacitance-High-Precision-Meter-LC100-S-/291333942316?pt=LH_DefaultDomain_0&hash=item43d4db2c2c | |

| 03:37 < Waffl3x> do you guys know of a circuit schematic design program? (I could draw it but I'm not very neat) | |

| 03:37 < sammyb> haha genewitch i'm sceptial too | |
| 03:37 < metacollin> still works great. For $17, definitely worth it. I wouldn't put more stock in the accuracy han like 5-10% but thats usually fine | |
| 03:38 < sammyb> not to say its not good value of course | |
| 03:38 < sammyb> yeah | |
| 03:38 < Waffl3x> okay thanks :) | |
| 03:38 < metacollin> genewitch: they are high precision. It works by counting a frequency. But they are only as accurate as the reference inductor and capacitors used, which are probably...uh, cheap rather than good :) | |

Granted, that's totally legit, they can't halt production to wait for a part, and you're on the other side of the planet and suck at mandarin (and cantonese if its hong kong. point is, you suck at both) so between timezones and language barriers, they gotta make a choice. And they will choose really fuckin cheap :). | |
| 03:45 < metacollin> I.e.: hand them all your connectors and precision parts, preferably by hand | |
| 03:45 < metacollin> 'them' meaning cheaper board houses | |
| 03:47 < genewitch> if i was going to make something i wouldn't mass produce anyhow | |
| 03:48 < genewitch> stuff is worth more if it's rare | |
| 03:48 < genewitch> sure, mass production means more money in general, but why? | |

| 04:00 < Brisance> is there anything besides power loss preventing using BJTs in boost converters instead of FETs? | |
| 04:00 < SuperBrainAK> ive used it fairly sparingly but it works ok as far as im concerned | |
| 04:00 < metacollin> so, I can design a dildo for lizards. I could have it mass produced, I just pay to do it. Or I can build one lizard dildo myself, by hand. Either way, its worth nothing because no one wants it. Lizards don't know how to fap. Just saying, just because there is only one lizard dildo, doesn't make it inherently valuable, or more valuable.

| 04:03 < Brisance> yesterday I noticed my wine tasting skills suck after a while of drinking beer and not red wine, | |
| 04:03 < gurki> i really should read electronics more often just after i had to go to work :D | |
| 04:03 < genewitch> Brisance: wine tasting is made up | |
| 04:03 < Brisance> I thought a syrah was merlot by taste | |
| 04:03 < genewitch> it all tastes like rancid grapes | |
| 04:03 < metacollin> genewitch: oooooooh. | |
| 04:03 < Bright> blown: capacitor | |
| 04:03 < metacollin> yes, we are talking about two totally different things lol. nvm, I agree | |
| 04:03 < Brisance> no. wine ratings are made up and they are all subjective | |
| 04:03 < genewitch> metacollin: and i agree with your assertions given your parameters as well | |
| 04:04 < genewitch> Brisance: people can't tell the difference between coke and pepsi, marlboro and camel... but somehow they can determine the difference between texan and california wine in a blind test? | |
| 04:04 < Brisance> but a pinot noir sure tastes differently than say a cabsauv | |

| 04:06 < genewitch> coke zero is the best tasting soda | |
| 04:06 < Johnsen> yes | |

| 04:06 < Brisance> yes that is hogwash, but grapes differ quite a bit by taste | |
| 04:06 < Johnsen> i thought zero is only deadly according to the sgar lobby | |
| 04:06 < metacollin> oh ok | |
| 04:06 < genewitch> if you say dr peppers i will /ignore you forefver | |
| 04:06 < Johnsen> i love dr pepper:p | |

| 04:07 < genewitch> Dumle29: what do you use | |
| 04:07 < Viper-7> a cheap wine can taste like an expensive one | |
| 04:07 < genewitch> i haven't found a "great' soda stream mix yet | |
| 04:07 < Brisance> metacollin, yes, I've read that, but there IS a difference between grape varieties | |
| 04:07 < genewitch> i love my soda stream because i don't have to get a DUI to keep drinking | |
| 04:07 < metacollin> no no I didn't realize that's what you're saying | |
| 04:07 < jsoft_> Hmmm | |
| 04:07 < Johnsen> soda stream woop, a mate of mine had that when we were kids 20y ago | |
| 04:07 < Dumle29> genewitch: 0.75 cola, 0.25 orange. And if I'm tired, 1 xtreme energy :P | |
| 04:07 < metacollin> that's definitely true. I mean, I've eaten different grapes and they taste different heh | |
| 04:07 < Brisance> try riesling and compare it to say chardonnay | |
| 04:07 < genewitch> ah diet cola and orange is always good | |
| 04:07 < Johnsen> the lemonade was good but the soda stream coke sucked | |
| 04:07 < jsoft_> with auido, If I have two signal sources, do I need to do anything special to mix them into one output? | |
| 04:07 < genewitch> even orange juice | |

| 04:08 < genewitch> metacollin: good if you get the water to like 34 degrees F before you do the buzzy buzz | |

| 04:08 < genewitch> metacollin: the only problem i have now is no one does the refills | |

| 04:09 < metacollin> genewitch: hahaha, welcome to the plight of paintballers | |
| 04:09 < genewitch> metacollin: they used sodastream bottles? | |
| 04:09 < jsoft_> Hmmm | |
| 04:09 < Dumle29> Yeah check if you have that problem. In Denmark it's easy to get refils | |
| 04:09 < metacollin> no, but they use CO2 | |
| 04:09 < genewitch> i thought they had all that compatible gear | |
| 04:09 < genewitch> oh i can get CO2 | |
| 04:09 < metacollin> are the cylinders not refillable? | |

| 04:09 < Brisance> I drink this amazing drink mostly at home: http://www.alecoq.ee/wordpress/wp-content/uploads/2014/12/aura_fruit_sidrun_1-5L.png it's somewhere between carbonated water and lemonade, that is lemon flavoured and only mildly sweet, traditional sodas are too sweet for my liking | |
| 04:09 < metacollin> What connector is on them? | |
| 04:09 < Johnsen> and methane | |
| 04:10 < genewitch> sodastream just has a proprietary threading | |
| 04:10 < metacollin> fuck | |
| 04:10 < Dumle29> yeah | |
| 04:10 < metacollin> The grocery store here has a refil cylindar lol | |
| 04:10 < genewitch> there's kits but they're not cheap and it's always some "uncleremus222xx" on ebay selling them | |

| 04:10 < Dumle29> Should be fairly easy to 3D print an adaptor, and then lost plastic cast it in alu | |
| 04:10 < Johnsen> tastes like tropical drink | |
| 04:10 < metacollin> it's been chillin untouched for months | |
| 04:10 < genewitch> i get the big bottles though | |
| 04:10 < metacollin> just one though | |
| 04:10 < genewitch> the little ones are crap | |

| 04:10 < Dumle29> genewitch: Little ones? | |
| 04:11 < genewitch> yeah, there's two sizes of sodastream cylinders | |
| 04:11 < metacollin> this one was about as tall as the soda stream itself | |
| 04:11 < Dumle29> genewitch: The CO2 canisters? There's only one in Denmark. The ones for ~60L of soda | |
| 04:11 < metacollin> is that big or little? Or are they all that height and its the diameter? I don't remember the actual co2 it said | |
| 04:11 < genewitch> Dumle29: mine say 130L | |
| 04:11 < Dumle29> metacollin: It'd be lengtth difference I'd think | |
| 04:11 < Johnsen> modern freebsd is having iqsues linux didnt have since years anymore, like having difficulties showing proper cpu loads on cpus that can throttle speed etc | |
| 04:11 < Dumle29> metacollin: Diameter is pretty fittted | |
| 04:11 < genewitch> girth | |
| 04:12 < genewitch> length is the same | |

| 04:12 < Brisance> the aura fruit thing has 6.1% sugar vs 10.9 in coca cola, which is perfect for me | |
| 04:12 < Brisance> not because energy, but because taste | |

| 04:13 < genewitch> heh, the ones with LEDs are automatic. you put the bottle against a rail, and tilt, and it locks. then you push this carriage down and the LEDs light up to tell you how much fizz | |
| 04:13 < genewitch> then the carriage goes up, bottle slides out ready to go | |
| 04:14 < Dumle29> lol. Yeah that's a bit overkill :P | |
| 04:14 < genewitch> 60L tanks though | |
| 04:14 < Dumle29> how much soda do you drink dude :P | |
| 04:14 < metacollin> is there a better way to chill the liquid you want to carbonate besides monitoring it with a thermometer frequently while its in your freezer? | |
| 04:14 < genewitch> mine's just got a grey button that you push till it buzzes 6 times | |
| 04:14 < Dumle29> genewitch: Oh that might be why :P | |

| 04:15 < genewitch> if you made a cap with pressure release at like 5PSI or whatever you could do dry ice, but carbonation works better if the liquid itself is cold | |
| 04:15 < Dumle29> depending on the moddle as well | |
| 04:15 < metacollin> oh wait, I guerss fridge temp is 35-38 degrees | |

| 04:22 < Johnsen> with a rpi? | |
| 04:22 < Johnsen> nah not something with tubes | |
| 04:22 < gurki> Johnsen: yay. everyone likes rpis | |
| 04:23 < gurki> (well. i dont. i kind of hate them^^) | |
| 04:23 < Johnsen> thet do? | |
| 04:23 < genewitch> gurki: i want a new one. i have 3 old ones | |
| 04:23 < genewitch> model B | |
| 04:23 < Brisance> depends on usage | |
| 04:23 < Johnsen> i use my rpi to stop my desk from wiggling | |
| 04:23 < Brisance> I hate most users of arduinos for example, not the arduinos themselves | |
| 04:23 < gurki> i never got the hype. they are basically just good for xbmc :/ | |
| 04:23 < Brisance> well most common usages to be exact | |
| 04:23 < genewitch> they're REALLY awesome application specific devices, and also good for testing arduino sensors and boards and stuff, since python is right there | |
| 04:23 < metacollin> build a metal detector? | |
| 04:23 < gurki> you kind of want a bbb for anything else | |
| 04:24 < Johnsen> and arcade/NEs emulator | |
| 04:24 < metacollin> that's nice and analog, and relatively easy | |
| 04:24 < metacollin> and useful | |
| 04:24 < metacollin> i dunno | |
| 04:24 < genewitch> gurki: only downside is only 2 analog in and they're trash | |
| 04:24 < Johnsen> python bah | |
| 04:24 < gurki> genewitch: python. baaah | |
| 04:24 < Johnsen> i hate python too | |
| 04:24 < metacollin> sssSSSssssSsssss | |
| 04:24 < gurki> Johnsen: <3 | |
| 04:24 < metacollin> python | |
| 04:24 < metacollin> pythons hisss right | |
| 04:24 < genewitch> gurki: everything's already written for you? and the backend is C, is that better? | |
| 04:24 < Johnsen> i like ruby :p but most pl hate that even more | |
| 04:24 < genewitch> i mean if you know C, grats | |
| 04:24 < metacollin> ruby ftw | |
| 04:24 < genewitch> they taught fuckin pascal at my school | |
| 04:25 < Johnsen> haha same | |
| 04:25 < genewitch> FAT LOT OF GOOD THAT DID | |
| 04:25 < gurki> genewitch: well im an hpc guy. i really cant stand the sluggish slow crappyness of python^^ | |
| 04:25 < Johnsen> but my school is quite a few years ago | |
| 04:25 < gpunk> lol perl is backend by C since the 80' | |
| 04:25 < Johnsen> turbo pascal 6 | |
| 04:25 < metacollin> I love ruby. I patiently await the day its not slow as fuck, or until that doesn't matter | |
| 04:25 < password2> rpi without python is a pain | |

| 04:25 < Johnsen> i only use my rpi for 2 things | |
| 04:25 < metacollin> spoiler: the answer is still no :( | |

| 04:25 < gurki> wouldnt call myself a c starter though | |
| 04:25 < genewitch> spoiler: yes | |
| 04:26 < metacollin> no one needs to make a website for that | |
| 04:26 < metacollin> its always on fire | |
| 04:26 < genewitch> it's so big | |
| 04:26 < metacollin> yeah | |
| 04:26 < Johnsen> but i just bought some stm32 | |
| 04:26 < password2> gurki: its not about the technical challenge , its about finding usefull information and libs | |
| 04:26 < Johnsen> i should play a bit with those | |

| 04:26 < metacollin> I was in napa recently, everything looked dead, no green | |
| 04:26 < password2> in thory the rpi would do c much better for basic electronics than python | |

| 04:27 < Johnsen> got im so irritated by freebsd not showing a load of 0.00 :p it makes me feel like my pc is slow | |
| 04:27 < genewitch> no one likes C | |

| 04:27 < genewitch> no one likes C++ | |

| 04:28 < gurki> you gotta be drunk to like that one | |
| 04:28 < Johnsen> c is neutral :p | |
| 04:28 < genewitch> it's a real specific language | |
| 04:28 < Johnsen> its not nice its not unnice :p | |
| 04:28 < gurki> genewitch: i know. i even know that there are ppl who like it. never got that though | |
| 04:28 < Johnsen> its handy for mcus tho | |

| 04:29 < gurki> FORTRAN | |
| 04:29 < Johnsen> meh | |
| 04:29 < gurki> i guess we can all agree that fortran sucks | |

| 04:36 < Johnsen> 2000fps and more | |
| 04:37 < LeEarl> lotsa kiddies these days love python et al(ruby). | |
| 04:37 < metacollin> why, I was influenced by god himself of course | |

| 04:37 * p0g0_ wonders what coding language the dieties prefer. | |
| 04:37 < Johnsen> when a unity game starts the unity splash screen is not framerate limited, nor moving, so that gets like 5000+ fps and then my gfxcard sings | |
| 04:37 < Brisance> I don't get the fps race | |
| 04:38 < genewitch> p0g0_: assembler | |
| 04:38 < Brisance> anything over your monitor fps is useless | |
| 04:38 < gpunk> yes | |
| 04:38 < Brisance> thus vsync on | |
| 04:38 < LeEarl> Johnsen, what u need 2000fps for? Mayb u can break N$A code with that? | |
| 04:38 < Brisance> and run at 75 | |
| 04:38 < intranick> im getting 52 extra hours pay on one check | |
| 04:38 < gpunk> but it means that at very high load | |
| 04:38 < Johnsen> did you see what i said? | |
| 04:38 < intranick> but im not paid hourly >.> | |
| 04:38 < gpunk> it will sustain a usable frame rate | |
| 04:38 < Johnsen> anyway | |
| 04:38 < LeEarl> paralell computing with 4 powerful gpus to break N$A code | |
| 04:39 < metacollin> dieties use perl for sure | |
| 04:39 < Johnsen> 4 lol | |
| 04:39 < Johnsen> you can get amazon gpu cloud accounts with a lot more gpu power afaik | |

| 06:24 < irseeyou> I built a BJT H-Bridge and tied the bases together for each side of the H-Bridge. It is turning on without any input -- I'm assuming the PNP is turning on the NPN from the base current and allowing current to flow through the circuit. How do I prevent this? | |
| 06:25 < SpeedEvil> is the npn on the + side? | |

| 08:48 < angelo_ts> no religion / no politic are always good rules, difficult to find ppl to agree on thise things | |
| 08:48 < LeEarl> legendary, in series the sum adds up. R = R1+R2. in parallel they become lower than the least. 1/r=1/r1+1/r2..etc. | |
| 08:48 < legendary> but how are the physically wired that makes them diferent from one another? | |
| 08:49 < LeEarl> legendary, so let's say u got two 1/2 ohm resistors. so when they are in series resistance becomes R = 1/2 + 1/2 = 1 hom | |
| 08:49 < LeEarl> ohm | |

| 09:53 < Encapsulation> _abc_, ? | |
| 09:53 < _abc_> Encapsulation: charging slas is easy, but if you make a mistake they will really ruin your life. | |
| 09:53 < LeEarl> crised_1, maybe u need to read about parking lot management automation. | |
| 09:53 < _abc_> Use a fuse on the line from the charger to the battery | |
| 09:53 < Encapsulation> is there a simple charging circuit you recommend? | |
| 09:53 < Encapsulation> what about connecting a laptop battery charger to it | |
| 09:54 < _abc_> Yes, but google images explains it better | |

| 09:54 < _abc_> Encapsulation: with a proper charging circuit | |
| 09:54 < Encapsulation> but I need some kind of overcharge protection | |
| 09:54 < _abc_> The simplest is a car bulb in series. | |

| 10:05 < Encapsulation> "Ideally, I would have a much better heat sink on the current regulator, but 317s are almost indestructible. When it starts to over-heat, it simply folds back the current and charges the battery longer and slower, which is fine for my application.

| 10:32 < blockh34d> if i have amicro and its driving some steppers, but i need more steppers off it than it was designed for, would using a couple pins off it and a shift register be the most effective way for me to timeslice (or whatever you'd call it, multiplex maybe?) those motors? | |
| 10:32 < blockh34d> i have a cb here with a similar design on it i'm using for now, the wicked device 6 motor shield | |

| 10:34 < blockh34d> hm so the micro would change a few port selection bits and that would route the output to the appropriate motor? | |

| 10:34 < blockh34d> seems like your suggestion would 'cost' less | |
| 10:34 < Johnsen> the and gate ;p | |
| 10:34 < blockh34d> right yeah i bet so | |
| 10:34 < Johnsen> using shiftregisters with timed pulses is more overhead | |
| 10:34 < blockh34d> thanks i'm putting that down on the big board of options to review | |
| 10:34 < Johnsen> since you need to write the shiftregister every time a pin changes i time | |
| 10:34 < blockh34d> i'm doing this for someone else so ultimately its their decision but i like the sound of that | |

| 10:49 < _abc_> apo__: dimmer triac | |
| 10:49 < blockh34d> hey i think i just smoked a board trying something dumb i'd like to avoid with the replacement i'm about to go buy | |
| 10:49 < LeEarl> ok :) | |
| 10:49 < _abc_> blockh34d: only thing is transit (non working) is slow, that's normally not a problem, you are not in a hurry. | |
| 10:49 < blockh34d> so what i did was feed 5v to this shields input lines, which use a pwm signal to basically set the output current of the steppers | |
| 10:49 < apo__> _abc_: huh, I thought power companies frowned upon those for bigger loads | |
| 10:49 < _abc_> blockh34d: 600rpm is 10mm/sec on a 1mm/turn lead screw | |
| 10:50 < _abc_> apo__: they do, but 2kW is not a large load | |
| 10:50 < blockh34d> _abc_: yah way faster than i expect to move, even when homing | |
| 10:50 < apo__> _abc_: Okay. Thanks :) | |
| 10:50 < Johnsen> haha | |
| 10:50 < _abc_> apo__: Also you can use full wave switching and 'cycle stealing' or 'skipping' which is not objectionable | |
| 10:50 < Johnsen> just dont get one of those chinese 4000W dimmers without heatsink :p | |
| 10:50 < blockh34d> so ok i smoked that board but it was my own fault for trying something dumb, to avoid that next time, should i use a current limiting resistor off the 5v i'm feeding those input pins? | |
| 10:51 < blockh34d> i dont really know it just sounds right to me | |
| 10:51 < blockh34d> if so, whats a good resistance for that? high? | |

| 11:46 < Chillum> I am making this: https://oshpark.com/shared_projects/ohLQpMwZ - most of it is lifted from this schematic: http://codeandlife.com/wp-content/uploads/2012/03/schematic.png - but it is not clear to me what C1 and R4 are supposed to be | |
| 11:47 < Chillum> R4 is most likely a current limiter for the led | |
| 11:47 < Chillum> but what is the cap for? and what capacity? | |
| 11:48 < Johnsen> where? | |
| 11:48 < Johnsen> i dont see caps ont he schematic | |
| 11:48 < Chillum> exactly | |
| 11:48 < Chillum> the PCB says it was lifted from that schematic | |
| 11:48 < Chillum> but it has extra parts and no parts list | |
| 11:48 < Chillum> I have figured out every part but the cap | |
| 11:48 < LeEarl> someone is stealing my ideas! | |
| 11:49 < Chillum> it is a very common project the usb keyboard stick | |
| 11:49 < Johnsen> r4 is for the led most likely | |
| 11:49 < Chillum> yes, a limier | |
| 11:49 < Chillum> limiter | |
| 11:49 < Johnsen> and c1 a normal 100nF power decoupling | |
| 11:49 < Chillum> that makes sense | |
| 11:49 < Johnsen> since i dont see any other caps on pcb and every Ic should have decoupling :p | |

| 11:50 < Chillum> hmmm the only 100nf caps I have are way too big to fit there hehe, I need to order some little ones | |
| 11:50 < Johnsen> and r4, you most likely dont want a whole 20mA (too bright) so you may get away with 1 to 2k | |

| 15:43 < _abc_> splud: the issue with clones is, open hardware is usually made initially by people in affluent countries to have fun, then later they realize it would be nice to sell some, and if it does sell then someone in Asia will grab the opportunity and copy it for less, pissing off the initial makers. | |

| 15:58 < blockh34d> i misunderstood your response at first | |
| 15:58 < jacekowski> blockh34d: printing something that has more than a dozen of transitors in it is going to be impossible | |

| 15:58 < splud> basically, buy us a 3D printer. We're not _designing_ something new. The rewards are all just crap things they'll print for you. | |
| 15:58 < jacekowski> blockh34d: also current 3d printers suck | |
| 15:58 < blockh34d> jacekowski: i would agree on both accounts | |
| 15:59 < blockh34d> but i would be ok with a device with even one transistor, at first | |
| 15:59 < blockh34d> gotta start somewhere | |
| 15:59 < blockh34d> and the printers get better at a rediculous pace | |
| 15:59 < jacekowski> it would struggle to make it small | |
| 15:59 < blockh34d> ya i agree | |
| 15:59 < jacekowski> clip printer has a future | |
| 15:59 < blockh34d> but oversized, whatever, its ok, 3d printed stuff is already oversized | |
| 15:59 < jacekowski> but that requires very specific chemicals to work with | |

| 17:31 < OSaucey> LeEarl: Yes | |
| 17:31 < TheAstro30> however I've seen people make one using a large diameter aluminimum tube and winding on #28 wire to 8R, tapped at 4 | |
| 17:31 < anddam> specifically I find a R_{in} value quite different than the textbook answer | |
| 17:31 < LeEarl> we studied de organ laws in Discrete math ;D forgot most of it though | |
| 17:31 < anddam> I meant point (c) at the link | |
| 17:31 < Brisance> hmm that seems like another good idea, but since I got the resistors, might as well use them | |

| 17:41 < LeEarl> dudes the easiest way to memorize xor truth table is to tnink of a blind person that can't tell the difference between similar things(0s or 1s) so if he sees 0 xor 0 then its 0 and likewise 1 xor 1 then 0 but if they are different he can see them so 1 xor 0 = 1 , 0 xor 1 = 1 ;D | |
| 17:41 < LeEarl> I think I should become a tutor of a sort ;D | |
| 17:41 < anddam> OSaucey: I know the theory (these are end of chapter problems, actually the latest so supposedly the hardest) what I don't agree is the numerical value, it seems to me that the book's answer are not coherent | |

| 17:42 < TheAstro30> there you go | |
| 17:42 < anddam> thanks | |
| 17:42 < kevtris> there's only four possible combinations. xor outputs a 1 when inputs are different, 0 when the same | |
| 17:42 < anddam> with a signal resitance 100k and a 499 R_{in} | |
| 17:42 < kevtris> hence it 'Excludes" the 11 state | |

| 17:43 < kevtris> the idea of it is but the actual != operator, I doubt it | |
| 17:43 < OSaucey> Then you can use current division to get i1, combine Rb1 and Rpi1 and find the voltage there, then gmVpi to get the voltage on the other side, and you keep working your way across | |
| 17:44 < OSaucey> I can try to work it out for you too | |

| 18:56 < splud> If your alternator is charging the battery at 16V, there's something wrong. | |
| 18:57 < jacobdel> its not a car, its a four wheeler | |
| 18:57 < splud> And if the battery is, without active charging, at 16.0V, it's not a typical car battery (12.6V), nor a well conditioned marine/truck/whatever at 24 (or 25.2). | |
| 18:57 < jacobdel> it's 16v from the alternator | |

| 18:58 < jacobdel> well, it ranges from 14v-16v when alternating is on, I dont see a problem with 16v high end | |
| 18:58 < splud> My point is that in an automobile, the horn isn't using a regulator - it's driven by the available voltage as-is. Just like the headlamps, etc. | |

| 19:40 < dhrosa> but there's lots of broths/soups that are mostly milk/cream as the liquid | |
| 19:40 < larrycv> my charger and cam reports 2 cell li-on as fully charged on 7.8V, but if I keep it on the battery longer it charges all the way up to 8.33V (it kept that voltage for 24 hours). so two questions: why is charger reporting full charge so soon? and what voltage should I aim for for a sweet spot between runtime and battery longevity? | |
| 19:40 < LeEarl> Loshki why? In Qatar they call it Thareed :) it is very delicious :) | |
| 19:40 < splud> Though some cereal (literally, grains) are used in damn fine soup: barley soup is wonderous, esp. in the windtertime. | |
| 19:40 < dhrosa> larrycv: 8.4 is "fully" charged (4.2V per cell) | |
| 19:40 < LeEarl> I tried it once when I was in washington state :) | |
| 19:41 < dhrosa> I personally prefer to not charge cells above 4.1V per cell. I lose like 5-10% of the possibly capacity, but gain a few 100 more cycles of longetivity | |

| 19:43 < splud> My guess, this ancient thing called "math". | |
| 19:43 < dhrosa> and I've personally measured the capacity difference between 4.1 and 4.2V on my li-ion packs, it's a not-very-significant capacity difference | |

| 19:47 < larrycv> that can do it automatically | |
| 19:47 < dhrosa> but 4.2V charge gets you in a situation where misbalanced cells will have to discharge much more quickly to stay balanced, and you risk colder temperatures causing damage to your cells if you're at a high voltage | |
| 19:47 < LeEarl> Loshki, ;D that reminds me, I think they shot the movie Taken 2 in Turkey. Liam Neeson loved that experience a lot. | |

| 19:47 < dhrosa> I set a timer on my phone for how long Iw ant to charge, then go check the voltage | |
| 19:47 < dhrosa> the charger charges to 4.2V per cell and can't be configured | |

| 19:48 < LeEarl> dhrosa, dude just use a TP4056 breakout or chip :] | |
| 19:48 < Loshki> dhrosa: probably better that way. The cheap charger clones have a reputation for being inaccurate after the decimal point. | |

| 21:34 < OSaucey> 25 watts and I'd say it's a coarse | |
| 21:34 < splud> And this was soldering the eth wires to pads on the heatsinks (which want to draw the heat away, so the soldering iron needs to be there long enough to keep the solder molten). | |

| 21:36 < dhrosa> I just think OSaucey's using a cattle brand as a soldering iron and a solid lead I-beam as his solder, only possible explanation | |
| 21:36 < splud> the solder I'm using is not merely < 1/2 the thickness of yours, but given it's circular, there's appreciably less mass. | |
| 21:36 < OSaucey> Ah, you got me. | |

| 21:37 < hmmmm> hi, I need to add padding to a hard drive to reduce vibration. is felting foam an okay material to use? i am concerned about a potential static buildup because the screws in question are very close to a PCB | |
| 21:38 < splud> if your soldering iron has enough power and a fine tip, you can get to very high temperatures, which allows you to deliver heat to a small area quickly, then remove the soldering iron before much of that heat travels along conductive paths. | |
| 21:38 < hmmmm> note that there is a metal screw connecting to a large metal plate going through this layer of foam | |
| 21:38 < OSaucey> I'm about to pop to radio shack, can any of you recoomend which solder to get? | |
| 21:38 < OSaucey> http://comingsoon.radioshack.com/soldering-tools-and-supplies?prefn1=productType&prefv1=Solder | |
| 21:39 < OSaucey> I guess they don't use lead anymore | |

| 21:39 < splud> lower wattage requires you to linger longer in order to heat things up enough to melt the solder (and larger diameter, as well as specific solder formulation, will require more heat), and that allows the heat to travel. | |

| 21:44 < hmmmm> it's just that the thing I am applying this foam to is old, so it's much more ESD sensitive than modern electronics | |
| 21:44 < splud> I prefer to freak cats out by taking scotch tape and wrapping it inverted into little loops, put them where you want to discourage the cat from jumping. | |

| 21:46 < hmmmm> in any case, I managed to find some pink static-buildup-resistant foam | |
| 21:46 < hmmmm> is it any better to use that instead? | |
| 21:46 < splud> You're concerned about the spinny thing inside the HD chassis leaking static out and having it stored in the foam that is grounded? | |
| 21:46 < hmmmm> more concerned about my own touch | |

Eventually I dropped the automated test part off my resume, because it just led to more automated test positions. That's not a problem with devtest, it's a problem with getting 'typecast' by your resume. | |

| 23:35 < dhrosa> some internet pdfs tell me a lot of SMPSes will run just fine with DC inputs way below the intended input range | |

| 23:36 < dhrosa> I believe that from a purely electrical standpoint.... AC/DC converters are just a rectifier and SMPS | |
| 23:36 < dhrosa> but I wonder if laptop power bricks bother sensing the presence of AC/DC or low voltage input | |

| 23:37 < dhrosa> http://i.stack.imgur.com/rEdOn.png here's a macbook charger schematic.. there's no reason the input couldn't be run off DC, unless there's some sort of fault detection circuitry | |
| 23:38 < _abc__> Normally they will run with 110V-20% ac in and even below | |

| 23:40 < dhrosa> yeah that schematic has no access to the pre-rectified voltage | |
| 23:41 < dhrosa> there's no reasonable way for it to detect AC vs. DC | |
| 23:41 < _abc__> Uvlo should trigger at ~130V dc in or below. You can probably run them at 90Vdc in at the lowest, at full specs (load). Ones with primary pfc might work even lower but active pfc may sabotage your plans. | |
