| uniqanomaly_ | with kivy.org you can package python applications into one .apk | 08:36 |
| delinquentme | how does this work? | 08:36 |
| uniqanomaly_ | someone would have to set server in tor with many many gigabytes of hdd space | 08:37 |
| delinquentme | whats this thing i just downloaded? | 08:37 |
| delinquentme | and who can I talk to about contributing? | 08:37 |
| uniqanomaly_ | its package with TOR anonymous network for android | 08:38 |
| uniqanomaly_ | http://en.wikipedia.org/wiki/Tor_%28anonymity_network%29 :> | 08:38 |
| kanzure | sympy is so weird | 08:39 |
| delinquentme | so yeah I know of TOR and android but... this isnt working is it? | 08:39 |
| kanzure | bool(Ge(3,4)) gives False (which is correct) | 08:39 |
| kanzure | bool(And(Le(3,4), Ge(3,4))) gives True | 08:39 |
| uniqanomaly_ | havent tested it but site says it does work so | 08:39 |
| kanzure | i'm pretty sure this is wrong >:o | 08:39 |
| delinquentme | uniqanomaly_, url for site? | 08:40 |
| uniqanomaly_ | https://www.torproject.org/docs/android.html.en | 08:40 |
| delinquentme | Ohh ok ok so this is just TOR for android | 08:41 |
| delinquentme | none of the interfacing for downloading etc | 08:42 |
| uniqanomaly_ | I wrote there "android tor" :P | 08:46 |
| uniqanomaly_ | dumping thing is *just idea* so far | 08:47 |
| uniqanomaly_ | an | 08:47 |
| uniqanomaly_ | :> | 08:47 |
| delinquentme | uniqanomaly_, its certainly in the right vein | 08:50 |
| delinquentme | now if only code was completely OS portable | 08:50 |
| delinquentme | i guess you could make an android script to run the actions ... and then drop that into whatever harvester application we've got on the web | 08:51 |
| delinquentme | How do you build it so that it interfaces w exiting code | 08:51 |
| delinquentme | AND allows for android portability | 08:51 |
| uniqanomaly_ | check out kivy.org | 08:51 |
| delinquentme | but that being said .. whats the real ends here ... and is hitting android really even necessary for the end goals | 08:52 |
| uniqanomaly_ | its mostly framework for opengl GUIs but you can package python code wit it into one .apk file | 08:52 |
| delinquentme | the end goal might just be get the shit onto an anon network | 08:52 |
| delinquentme | no shit! | 08:52 |
| uniqanomaly_ | :> | 08:52 |
| delinquentme | and .apk is "android package file" ? | 08:52 |
| uniqanomaly_ | yea | 08:52 |
| kanzure | delinquentme: android gives you a good proxy on college campuses, that's the point | 08:53 |
| kanzure | but i don't think tor helps that much | 08:53 |
| kanzure | just give them a custom http proxy that reports back to you, like any other botnet | 08:53 |
| delinquentme | like its a fucking wet dream no doubt | 08:54 |
| delinquentme | #how? | 08:54 |
| kanzure | what part are you asking how for? | 08:54 |
| delinquentme | how: create totally "illegitimate" quiet destruction of massive publishers done in the name of anaonymity | 08:55 |
| delinquentme | RUHHH | 08:55 |
| delinquentme | ru kidding me | 08:55 |
| delinquentme | engineer this shit and then tag it w anon? | 08:55 |
| kanzure | i think you're just spewing jibberish | 08:56 |
| bkero | gibbering | 08:56 |
| delinquentme | NAH! man! | 08:56 |
| kanzure | do you have an actual question about the technical aspects? | 08:56 |
| delinquentme | kanzure, this is engineering, not research .. so its totally doable | 08:56 |
| -!- pasky_ is now known as pasky | 08:57 | |
| delinquentme | but like im just mulling over the societal repercussions | 08:57 |
| kanzure | ok.. then why did you say: 08:54 < delinquentme> #how? | 08:57 |
| kanzure | no you're changing subjects now | 08:57 |
| delinquentme | what im saying is that if you engineer something like this to topple these publishers from the inside | 08:57 |
| kanzure | i'm not convinced you're reading my messages | 08:58 |
| delinquentme | and then! tag it as doing of anonymous | 08:58 |
| delinquentme | whoever is running it would eat that shit up .. brand it as their own | 08:58 |
| delinquentme | idk | 08:59 |
| delinquentme | it feels good | 08:59 |
| delinquentme | like | 08:59 |
| delinquentme | masturbation | 08:59 |
| uniqanomaly_ | technical masturbation | 09:00 |
| uniqanomaly_ | delinquentme: someone gotta setup server and write teh code | 09:00 |
| delinquentme | uniqanomaly_, nah this is not technical masturbation but idealogical masturbation | 09:01 |
| kanzure | you're going around in circles | 09:01 |
| kanzure | go die in a hole somewhere | 09:01 |
| delinquentme | but at what point does that masturbation get you the courage to actually go tell that girl you'd like to bone her brains out? | 09:01 |
| uniqanomaly_ | delinquentme: when she has a hole in her head | 09:01 |
| delinquentme | lol | 09:01 |
| delinquentme | NOW | 09:02 |
| delinquentme | NO** wrong answer | 09:02 |
| delinquentme | ok ok ok so | 09:02 |
| delinquentme | god | 09:02 |
| delinquentme | how anonymous is this IRC chat again? | 09:02 |
| uniqanomaly_ | not at all | 09:02 |
| delinquentme | sometimes I wish there were no logs at all | 09:02 |
| delinquentme | ^^ | 09:02 |
| uniqanomaly_ | logs on the internets means google has it means US gov has it | 09:02 |
| delinquentme | you guys should come over and stay in my room | 09:02 |
| delinquentme | #noHomo | 09:02 |
| delinquentme | so we'd need to fucking chat on tor | 09:03 |
| delinquentme | lol | 09:03 |
| delinquentme | it could probably handle that bandwidth | 09:03 |
| uniqanomaly_ | right, next time ask phone numbers first, and then say #noHomo | 09:03 |
| uniqanomaly_ | ok maybe too much californication lately | 09:03 |
| delinquentme | kanzure, so i really like the observation of the android ad the solid proxy | 09:04 |
| kanzure | we talked about android/http proxies last week | 09:04 |
| delinquentme | how to write this thing in as minimal code as possible | 09:04 |
| kanzure | who cares about minimum? | 09:04 |
| delinquentme | what parts are distinctly android which are distinctly web services | 09:05 |
| delinquentme | god damn v | 09:05 |
| delinquentme | http://www.youtube.com/watch?v=Xyaw__64gU8 | 09:05 |
| kanzure | android http proxy, that's all.. | 09:05 |
| delinquentme | too much gangster dubstep arrogance | 09:05 |
| kanzure | what's hard to understand about that :( | 09:05 |
| delinquentme | so from a student activists perspective | 09:05 |
| delinquentme | they're logging in w the university credentials | 09:05 |
| delinquentme | our end needs to locate whatever access to the journals | 09:06 |
| delinquentme | how do we do that | 09:06 |
| kanzure | i'd tell you what to do but the reality is that you never take my advice | 09:06 |
| delinquentme | i know @ pitt there was a separate service | 09:06 |
| delinquentme | well lets circle jerk for a little while kanzure | 09:06 |
| kanzure | no | 09:06 |
| kanzure | no circle jerking | 09:06 |
| delinquentme | kk | 09:06 |
| kanzure | just ask me what you need. | 09:06 |
| delinquentme | holdup i need to consult my librarian | 09:07 |

| delinquentme | ParahSailin, >>>>>>>>>> | 09:09 |
| delinquentme | ok so | 09:09 |
| delinquentme | kanzure, access w the student credentials | 09:09 |
| kanzure | what about it? | 09:10 |
| eudoxia | yo | 09:10 |
| delinquentme | they need to be able to hit the research journal interface through a connection ... do they have access to that from their phone | 09:10 |
| delinquentme | ? | 09:10 |
| kanzure | if they sign on to campus wifi then they are assigned an internal ip address | 09:10 |
| delinquentme | google wouldnt be happy w us | 09:10 |
| delinquentme | you know this? | 09:10 |
| kanzure | most publishers authenticate by ip address | 09:10 |
| kanzure | who cares about google, stay on target | 09:11 |
| * delinquentme evil grin | 09:11 | |
| delinquentme | but what I'm saying is YES theyll be connected to university wifi | 09:11 |

| delinquentme | but does that connection necessarily facilitate a connection to the interface to whatever that journal management program is | 09:12 |
| delinquentme | wtf was it called proxy or | 09:12 |
| delinquentme | basically that login system | 09:12 |
| kanzure | ezproxy is for when you are outside the university network. | 09:13 |
| delinquentme | so internal ip connection guarantees access to journal interfaces | 09:14 |
| delinquentme | ^^^ this is what im curious about | 09:14 |
| kanzure | in the vast majority of cases the answer is yes | 09:15 |
| delinquentme | i guess the other thing is that we'll easily have enough interfaces which *DO* have that access to get the journals | 09:15 |
| delinquentme | do journals pay money into research? | 09:16 |
| delinquentme | or do they fund research in any manner at all? | 09:16 |
| kanzure | who cares | 09:16 |
| kanzure | and the answer is no. | 09:17 |
| Mokbortolan_ | I emailed my brain interface idea to the PhD behind the senseg technology | 09:46 |
| delinquentme | kanzure, you're still planning to move to SV right? | 09:47 |
| kanzure | delinquentme: sorta yes | 09:54 |

| kanzure | yeah | 11:39 |
| delinquentme | thats the same thing newresearcher was reporting on | 11:40 |
| kanzure | yes but the claims seem a little exaggerated | 11:43 |
| kanzure | this is why the FDA exists - to regulate claims like this | 11:43 |
| delinquentme | kanzure, is there any reason a RESTFUL api cant be built on RoR? | 11:43 |
| kanzure | i think it's great they are making a kit for this, but i'm not sure it's legal to claim all those benefits o.o | 11:43 |
| delinquentme | Im taking a break on these bastardized Jruby gems and migrations and going right to rails | 11:43 |
| kanzure | delinquentme: you can make a restful api on rails.. what's the problem? | 11:44 |
| chris_99 | it looks like its meant to be a joke to me kanzure | 11:44 |
| kanzure | i don't think so | 11:44 |

| chris_99 | to the right of that | 11:45 |
| chris_99 | it doesn't look serious at all | 11:45 |
| kanzure | that's just their marketing | 11:45 |
| kanzure | i.e. their way of saying "hey we also waste time on 4chan" | 11:45 |

| kanzure | hi Reid_Berryman | 12:13 |
| Reid_Berryman | hey! I was told about this chat from Bryon who's working on a few hardware projects over on this page http://diyhpl.us/~bryan/papers2/neuro/ultrasound/ | 12:14 |
| Mokbortolan_ | aww yeah | 12:15 |
| Mokbortolan_ | $99 for an IC and a resistor | 12:15 |
| Reid_Berryman | He refered me here because of the nature of a website we launched at a 54 hour startup company, which has two hours remaining. | 12:15 |
| Mokbortolan_ | I actually had a similar idea | 12:15 |
| kanzure | Reid_Berryman: you might also find #startups useful | 12:16 |
| Reid_Berryman | Well, I understand what we made, I also understand our abnormaly large price point. | 12:16 |
| Reid_Berryman | Thanks Kansure | 12:17 |
| Reid_Berryman | Its a kit aimed at those with little or no electronic experience. Simply for self testing too on the concept. | 12:18 |

| chris_99 | i'm guessing the position of the electrodes is important Reid_Berryman? | 12:23 |
| Reid_Berryman | Yep, to achieve different effects and reach the flow state they have to be in different positions. chris_99 | 12:25 |
| Mokbortolan_ | Reid_Berryman: so, what sort of safety measures will it have? | 12:26 |
| Reid_Berryman | Sorry for the delay Mokbortolan, our design is not offically created outside of prototype, but will have a fuse to prevent an over voltage & amperage. Our IC also stays within the best practice range from research | 12:34 |
| Mokbortolan_ | Oh jeez | 12:35 |
| Mokbortolan_ | a fuse, eh? | 12:35 |
| Mokbortolan_ | the only fuse I could find that would work was from Littelfuse | 12:35 |
| Mokbortolan_ | and they're like, $30/ea | 12:36 |
| Mokbortolan_ | I'm also designing my own circuit | 12:36 |
| Mokbortolan_ | why'd you choose that over the LM334, btw? | 12:36 |

| Mokbortolan_ | huh | 12:50 |
| Mokbortolan_ | an audio amp | 12:50 |
| chris_99 | its an op-amp yeah | 12:51 |

| ThomasEgi | what do you want to use the op-amp for? | 12:51 |
| chris_99 | is it just me or does that alldatasheet not actually work | 12:52 |

| ThomasEgi | try downloading the pdf. better to have a local copy anyway. | 12:53 |
| ThomasEgi | so... may i ask what you want to use it for? | 12:53 |
| chris_99 | yay works in opera but not FF for some reason for me | 12:54 |
| chris_99 | who are you talking to ThomasEgi? | 12:55 |
| ThomasEgi | you. i guess. | 12:55 |
| chris_99 | ah, i was just curious how it works | 12:56 |
| chris_99 | i'd be too scarred to try it out myself | 12:56 |
| ThomasEgi | how what works? | 12:56 |
| chris_99 | the device we're talking about | 12:56 |
| chris_99 | the brain stimulation thingy | 12:56 |
| chris_99 | tDCS | 12:57 |
| Mokbortolan_ | I thought about selling kitas | 12:58 |
| Mokbortolan_ | kits | 12:58 |
| chris_99 | i'd be scarred people could hurt themselves with it | 12:58 |
| chris_99 | and sue you | 12:58 |
| Mokbortolan_ | but mine would have a fair bit more protection than an op amp :p | 12:58 |
| Mokbortolan_ | yep | 12:58 |
| chris_99 | it's a power amp actually, that was my bad | 12:58 |
| ThomasEgi | currents and neurons, not an easy mix. interesting one none the less | 12:59 |
| Mokbortolan_ | would it be appropriate? | 13:00 |
| Mokbortolan_ | I was planning on using a linear current regulator | 13:00 |
| Mokbortolan_ | two in series | 13:00 |
| ThomasEgi | why the need for a power-amp? | 13:00 |
| ThomasEgi | what currents are we talking about here? | 13:00 |
| Mokbortolan_ | 2ma | 13:00 |
| chris_99 | i'm curious about that too | 13:00 |
| Mokbortolan_ | with resistance varying from 100ohms to 20k | 13:00 |
| ThomasEgi | pretty much every op-amp can deliver 2mA | 13:00 |
| chris_99 | yeah thats what i thought you could just use a 741 | 13:01 |
| chris_99 | surely | 13:01 |
| -!- Reid_Berryman [~Admin@216.157.197.7] has quit [Quit: Leaving.] | 13:01 | |
| Mokbortolan_ | 334 is more sensitive | 13:01 |
| chris_99 | sensitive to what though? | 13:01 |
| Mokbortolan_ | err | 13:01 |
| chris_99 | its only being used as an output | 13:01 |
| chris_99 | from a static signal | 13:01 |
| Mokbortolan_ | sorry, it has a range more appropriate to the required current | 13:01 |
| ThomasEgi | if you just want a constant current source with 2mA, you dont need much precision | 13:02 |
| Mokbortolan_ | well, you do if you want to range from .5 to 2 | 13:02 |
| Mokbortolan_ | I dunno though, I'm talking out of my butt, I'm not an EE :p | 13:02 |
| ThomasEgi | in that case, even a npn+ poti is good enough | 13:02 |
| Mokbortolan_ | I read some folks talking about using a zener diode | 13:03 |
| Mokbortolan_ | then I looked up what a zener diode did :p | 13:03 |
| ThomasEgi | they are good for keeping a reference voltage | 13:03 |
| ThomasEgi | but on their own, they are no good for constant-current. | 13:03 |
| ThomasEgi | you would need a voltage to current converter then. | 13:04 |
| chris_99 | "Currently, the accepted maximum current for human use is 2 mA and usually 1 mA or less is used." | 13:04 |
| ThomasEgi | so.. all you want is a regulate-able current source? that goes from 0 to 2mA? | 13:07 |
| chris_99 | yup | 13:08 |
| chris_99 | so an omp-amp | 13:08 |
| Mokbortolan_ | and can adjust to changing resistance | 13:08 |
| chris_99 | + resistor | 13:08 |
| ThomasEgi | Mokbortolan_, a resistor itself aint good enough :) | 13:08 |
| Mokbortolan_ | because during the session the resistance will go down | 13:08 |
| Mokbortolan_ | nope | 13:08 |
| Mokbortolan_ | you can use one if you have an ammeter in the circuit | 13:09 |
| Mokbortolan_ | and manually adjust | 13:09 |
| Mokbortolan_ | but I'd rather have an IC do that for me :p | 13:09 |
| ThomasEgi | easy enough | 13:09 |
| kanzure | what's the resolution on tdcs? my understanding was that it the repeatability on where exactly you're stimulating in the brain is not useful with this technique | 13:09 |
| ThomasEgi | got a npn transistor, a diode, and a few resistors around? | 13:09 |
| Mokbortolan_ | no | 13:09 |
| Mokbortolan_ | I have 2 LM334's and a big bunch of resistors :p | 13:09 |
| ThomasEgi | no transistors? | 13:10 |
| Mokbortolan_ | nope | 13:10 |
| ThomasEgi | odd. | 13:10 |
| Mokbortolan_ | I don't have a big electronics it | 13:10 |
| Mokbortolan_ | kit | 13:10 |
| Mokbortolan_ | I bought these parts specifically for my project | 13:10 |
| Mokbortolan_ | I have to sit down and go through all my unlabeled resistors | 13:10 |
| Mokbortolan_ | and find the right ones to set up the prototype circuit | 13:10 |
| ThomasEgi | so.. lm334 then.. | 13:10 |
| ThomasEgi | and a 9v battery i guess? | 13:11 |
| Mokbortolan_ | oh, a fellow named dhzz has helped me design a circuit | 13:11 |
| Mokbortolan_ | yes | 13:11 |
| Mokbortolan_ | I just have to do it | 13:11 |
| ThomasEgi | got a poti? | 13:11 |
| Mokbortolan_ | I have a 10k pot :p | 13:11 |
| ThomasEgi | oh, you have the shematic already?... | 13:11 |
| Mokbortolan_ | yep | 13:11 |
| ThomasEgi | okay. | 13:11 |
| Mokbortolan_ | I was just wondering why this guy was using that IC | 13:11 |
| ThomasEgi | no idea | 13:11 |
| Mokbortolan_ | didn't seem appropriate, but I'm not an EE | 13:11 |
| chris_99 | 99$ seems a hell of a lot imo | 13:12 |
| ThomasEgi | but you can get a constant current source with just a poti , an npn transistor, and one resistor. | 13:12 |
| chris_99 | for those components | 13:12 |
| Mokbortolan_ | what's a poti? | 13:12 |
| ThomasEgi | bill of material probaly range below 10cent | 13:12 |
| chris_99 | potentiometer | 13:12 |
| Mokbortolan_ | ok, yeah, thought so | 13:12 |
| Mokbortolan_ | just wanted to make sure | 13:12 |
| Mokbortolan_ | ThomasEgi: yeah, but then you gotta figure the cost of putting it together, making the site, etc, etc | 13:13 |
| Mokbortolan_ | would cost at least $3/unit | 13:13 |
| ThomasEgi | uhm.. nope :D | 13:13 |
| chris_99 | theres a breadboard too! ;) | 13:13 |
| Mokbortolan_ | and you're probably not going to sell many | 13:13 |
| Mokbortolan_ | I see a market of about maybe 20 | 13:13 |
| Mokbortolan_ | any profits would get eaten up in insurance costs :p | 13:13 |
| ThomasEgi | why insurance :D | 13:13 |
| ThomasEgi | building those things as constant current source | 13:14 |
| ThomasEgi | why would you need any insurance. if people use it for medical stuff, their problem. | 13:14 |
| Mokbortolan_ | oh sure, but then you can't emblazon your page with "tDCS will make you a genius" type of stuff | 13:14 |
| Mokbortolan_ | or reference tDCS really at all | 13:14 |
| Mokbortolan_ | this is the FDA's domain | 13:14 |
| kanzure | you can reference tDCS | 13:14 |
| kanzure | just don't say "OUR DEVICE HAS BEEN SHOWN TO MAKE YOU A FUCKING EINSTEIN AND/OR HITLER" | 13:14 |
| Mokbortolan_ | no, you can't | 13:15 |
| Mokbortolan_ | really | 13:15 |
| chris_99 | if they sell it as a 'kit' can they get away without any proper testing | 13:15 |
| Mokbortolan_ | they'll even look at your blog posts | 13:15 |
| kanzure | you can get away without proper testing if you don't claim it's a medical device | 13:15 |
| Mokbortolan_ | forum posts, etc | 13:15 |
| Mokbortolan_ | they'll treat this like they would veterinary steroid supplements | 13:15 |
| kanzure | also you can't really claim positive benefits.. | 13:15 |
| ThomasEgi | anyway. it is a 3 part-circuit. , 6 parts if you want to do it really well. | 13:15 |
| Mokbortolan_ | I've read a bit on how the FDA works in this regard | 13:15 |
| kanzure | and you know, if you *could* claim positive benefits, i'm not sure tDCS warrants such huge claims abotu its effects | 13:16 |
| Mokbortolan_ | <--- runs a small piracetam store | 13:16 |
| chris_99 | yeah i'm sceptical about tDCS in general at the moment, although i need to read more about it | 13:16 |
| Mokbortolan_ | bbl, errands | 13:16 |
| Mokbortolan_ | though | 13:16 |
| kanzure | i mean, it certainly does something.. heh | 13:17 |
| chris_99 | heh, even if that is only a tingly sensation | 13:17 |
| kanzure | but so would punching yourself in the head | 13:17 |
| Mokbortolan_ | I want to hear Reid_Barryman's answers to my questions | 13:17 |
| kanzure | he left | 13:17 |
| chris_99 | ask on their site Mokbortolan_ | 13:17 |
| Mokbortolan_ | as soon as I asked about the IC's he was using :p | 13:17 |
| kanzure | he's just at a startup competition thing | 13:17 |
| Mokbortolan_ | probably a coincedence, I'm sure | 13:17 |
| kanzure | the goal is to use bootstrap.js/stripe.js as fast as possible | 13:18 |
| Mokbortolan_ | coincidence | 13:18 |
| kanzure | so they haven't actually tested anything, i'm sure. | 13:18 |
| Mokbortolan_ | well, I guess I'll just have to beat him to the market | 13:18 |
| * Mokbortolan_ sighs. | 13:18 | |
| kanzure | he already beat you :P by putting up an order form | 13:18 |
| Mokbortolan_ | he did! | 13:18 |
| kanzure | i know, it's annoying | 13:18 |
| kanzure | even with no product.. | 13:18 |
| Mokbortolan_ | I wouldn't do that until I had product | 13:18 |
| Mokbortolan_ | but that's just me | 13:18 |
| kanzure | right | 13:18 |
| kanzure | or a product that, i dunno, also wokrs | 13:19 |
| Mokbortolan_ | hahaha | 13:19 |
| Mokbortolan_ | well, that's up to investigation :p | 13:19 |
| chris_99 | what's bootstrap.js not heard of that one | 13:19 |
| uniqanomaly_ | market verification | 13:19 |
| Mokbortolan_ | bbl | 13:19 |
| kanzure | chris_99: a library by twitter to help you throw up sites quickly | 13:19 |
| kanzure | without repeating common bullshit from site to site | 13:19 |
| kanzure | there's tons of these libraries | 13:19 |
| kanzure | bootstrap just so happens to be pretty handy | 13:19 |
| kanzure | and for some reason, popular | 13:19 |
| Mokbortolan_ | http://csp.org/practices/entheogens/docs/roberts-immune.html | 13:20 |
| chris_99 | ah, do they handle the hosting or something for you, and you point your dns to them | 13:21 |
| Mokbortolan_ | Do entheogen-induced mystical experiences boost the immune system? | 13:21 |
| Mokbortolan_ | Psychedelics, peak experiences, and wellness | 13:21 |
| * Mokbortolan_ gets some circuit boards made. | 13:22 | |
| kanzure | chris_99: no | 13:23 |
| kanzure | chris_99: it's a javascript library | 13:23 |
| chris_99 | oh its just ui stuff | 13:23 |
| chris_99 | gotcha | 13:23 |
| chris_99 | on an off-topic note, i've just started using the Play framework | 13:23 |
| kanzure | play? | 13:25 |
| chris_99 | http://www.playframework.org/ it's a java based one | 13:25 |
| chris_99 | i know java isn't very popular these days, but it's got some nice features | 13:26 |

| ThomasEgi | chris_99, http://home.arcor.de/positiveelectron/files/controllable-cc-source.png | 13:34 |
| chris_99 | nice :) | 13:35 |
| ThomasEgi | should give out 0 to 2 mA | 13:38 |
| ThomasEgi | better to test it with an ampere meter befor connecting it to your skull tho | 13:39 |
| roksprok | ThomasEgi: What are you using for electrodes? | 13:39 |
| ThomasEgi | me? i dont use anything | 13:39 |
| nsh_ | walrus tusks | 13:40 |
| ThomasEgi | i just slammed together a constant current source :D | 13:40 |
| ThomasEgi | that's all | 13:40 |
| ThomasEgi | i once looked for eleectrodes. | 13:40 |
| roksprok | ah...well, i actually tried out several homemade ones last night | 13:40 |
| roksprok | and they all failed | 13:40 |
| ThomasEgi | and found a nice company nearby selling in low quantities for a reasonable price. pretty much everything you can ask for | 13:40 |
| ThomasEgi | silver-cloride was high on my list | 13:41 |
| ThomasEgi | http://www.science-products.com/Products/CatalogG/IVM-AgAgCl-Pellets/ivm.html those were my favorits. altho i never actually bought any. | 13:42 |
| ThomasEgi | they also offer a great range of other scientific products. | 13:42 |
| roksprok | wow, thanks those look amazingly good | 13:42 |
| roksprok | something else to look at is galvanic vestibular stimulation | 13:43 |
| ThomasEgi | if they wont ship to your place, just tell me, i'll try picking them up from their office then. | 13:43 |
| roksprok | it uses about the same current | 13:43 |
| roksprok | and would be a good 'proof current is flowing' | 13:43 |
| ThomasEgi | chris_99, oh.. wait. thet circuit has a mistake :D | 13:43 |
| roksprok | as well as a hit if you are in meetings with investors/potential employees/ etc. | 13:44 |
| roksprok | thanks | 13:44 |
| ThomasEgi | chris_99, updated the file, same link. just refresh. the diode D2 was the wrong way round | 13:47 |
| ThomasEgi | chris_99, bill of materials for the circuit, 49 euro-cent, in single-quantities. | 13:54 |
| ThomasEgi | 49.4 to be precise | 13:54 |
| chris_99 | hehe | 13:54 |
| chris_99 | the main cost for their project is the electrodes + breadboard | 13:55 |
| chris_99 | are you sure that circuit would only give 2mA out | 13:56 |
| ThomasEgi | yeah | 13:56 |
| ThomasEgi | pretty sure | 13:56 |
| ThomasEgi | you can test tho | 13:56 |
| ThomasEgi | that means. if your battery is not going over the maximum voltage of the transistor, | 13:56 |
| ThomasEgi | that would be around 40 volts or so | 13:56 |
| ThomasEgi | if the transistor dies. you'r doomed anyway :D | 13:57 |
| chris_99 | i'd play around simulating it in LTSpice but i can't get wine running | 13:58 |
| ThomasEgi | if you increase the value of R2 it will be even less current | 13:59 |
| chris_99 | R2 seems to be what's controlling the current really | 13:59 |
| ThomasEgi | i can explain to you. but i just got invinted to a game. so it will have to wait like.. maybe 40 to 50 minutes | 13:59 |
| chris_99 | unless i've missed something isn't the collector current 100mA | 14:14 |
| chris_99 | for that | 14:14 |
| ThomasEgi | na. | 14:18 |
| ThomasEgi | i will explain soon. maybe 20 minutes :) | 14:18 |
| -!- elmom [~elmom@hoas-fe3ddd00-25.dhcp.inet.fi] has quit [Ping timeout: 276 seconds] | 14:20 | |
| ThomasEgi | ok. they played fast. and are up for another game :D | 14:21 |
| chris_99 | got it now, the guys in electronics, reminded me of Ic = Ib * hFE | 14:22 |
| ThomasEgi | in this case. Ib is self adjusting. because if you increase the voltage at the Base, the emitter will follow (minus the BE voltage drop) | 14:24 |
| ThomasEgi | so you pretty much get a voltage forced on R2. which defines the current | 14:24 |
| chris_99 | so whats the gain for this transistor? | 14:27 |

| ThomasEgi | chris_99, it doesnt matter | 14:40 |
| ThomasEgi | will be back in. like 15 minutes or so | 14:40 |
| ThomasEgi | ok. now i have time again | 14:52 |
| ThomasEgi | so. i will explain from left to right R1 and D1 make a constant voltage, of 4.7V | 14:53 |
| ThomasEgi | just to be independand from the battery or powersupply voltage | 14:54 |
| ThomasEgi | then comes the poti and the diode D2 | 14:54 |
| ThomasEgi | D2 is in forward-direction. so it drops about 0.7 volt. it compensates for the transistors BE-voltage drop, which is about the same. | 14:55 |
| chris_99 | so whats the voltage at B? | 14:55 |
| ThomasEgi | between 0.7 and 4.7 volt | 14:55 |
| ThomasEgi | with respect to ground | 14:56 |
| chris_99 | ok so the transistor's biased to be always on | 14:56 |
| ThomasEgi | no | 14:56 |
| ThomasEgi | the transistor's current depends on the B-E voltage | 14:56 |
| chris_99 | transistors are normally on at 0.6V+ | 14:56 |
| ThomasEgi | between 0.6 and 0.7 V jeah | 14:57 |
| chris_99 | ok so the transistor is always on then | 14:57 |
| ThomasEgi | hehe. not really | 14:57 |
| ThomasEgi | it is not a discrete on or off. | 14:57 |
| chris_99 | above 0.6v it's 'on' though | 14:58 |
| ThomasEgi | nono | 14:58 |
| ThomasEgi | that is where R2 kicks in. | 14:58 |
| chris_99 | i understand its analogue | 14:58 |
| ThomasEgi | imagine a B-ground voltage of 3 volt | 14:58 |
| ThomasEgi | that woult, without R2, turn the transitstor on. | 14:58 |
| ThomasEgi | that would make a lot of current flow through the transistor. | 14:58 |
| ThomasEgi | . now we add R2. | 14:58 |
| chris_99 | so what current range do you reckon you're circuit would give? | 14:59 |
| ThomasEgi | wait for the explanation of R2 :) | 14:59 |
| ThomasEgi | if you put 3volt on B, then a big current flows through the transistor, which in turn, drops a voltage at R2 | 14:59 |
| ThomasEgi | which again. increases the potential of E, and therefore reduces the BE voltage again. | 15:00 |
| ThomasEgi | it is sort of self-regulating. the higher the voltage at B, the higher the current, the higehr the voltage drop at R2 | 15:00 |
| ThomasEgi | the actual current that flows is roughly the voltage between B and ground , minus the BE saturation voltage, and that divided by R2 | 15:01 |
| ThomasEgi | so whatever happens, your current will never ever rise over (4.7V-0.6V)/R2 | 15:02 |
| chris_99 | what formulae is that from? | 15:02 |
| ThomasEgi | from the circiut | 15:03 |
| ThomasEgi | since i added D2, it gets even easier | 15:03 |
| ThomasEgi | as d2 drops about the same voltage as BE. which is ,about 0.7 volt | 15:03 |
| ThomasEgi | ah wait | 15:03 |
| ThomasEgi | bullshit :D | 15:04 |
| ThomasEgi | na | 15:04 |
| ThomasEgi | wait again | 15:04 |
| ThomasEgi | no.. it is correct | 15:04 |
| ThomasEgi | sry. am a bit low on food for hours | 15:04 |
| ThomasEgi | simplified, it is roughly 4V/R2 | 15:04 |
| ThomasEgi | given your transistor is alive. | 15:05 |
| ThomasEgi | and not broken. | 15:05 |
| ThomasEgi | this formular neglects a few minor effects. but the error introduced by that is smaller than the resistor tollerances. so no need to drag it around | 15:05 |
| ThomasEgi | the circuit itself is rather stable, and should work with a veriety of parts, the values of R2 and D1 define the maximum current so you probably want to stick with them | 15:08 |
| ThomasEgi | hm.. i am afraid my explanation went right over any non EE head in here. | 15:09 |
| ThomasEgi | feel free to ask question :) i'll try to explain | 15:09 |
| chris_99 | i'm just reading up on the transistor formulae now :) | 15:10 |
| ThomasEgi | R = U / I | 15:11 |
| ThomasEgi | oh transistor | 15:11 |
| ThomasEgi | sry. read resistor | 15:11 |
| ThomasEgi | transistors are nonlinear parts | 15:11 |
| chris_99 | indeed | 15:11 |
| ThomasEgi | theyr formulars are pretty dificult | 15:11 |
| ThomasEgi | and. you probably wont be able to figure out anything from looking at them | 15:12 |
| chris_99 | i need to order 'the art of electronics' | 15:12 |
| ThomasEgi | but. as you know. below the 0.6 volt, the transistor is non-conducting | 15:12 |
| chris_99 | was recommended it a while ago | 15:12 |
| ThomasEgi | means it is "off" | 15:12 |
| ThomasEgi | if you go above that voltage, the base-current will start to flow (and with a multiple of that, the collector current) | 15:13 |
| ThomasEgi | the emitter current is basis+collector current. but since the collector current is usually hundret times bigger. collector and emmiter are almost equal. | 15:13 |
| ThomasEgi | the more the transistor "turns on" , means if more current flows, the resistor R2 will reduce the BE voltage again. | 15:14 |
| ThomasEgi | so it counteracts. and balances. | 15:15 |
| ThomasEgi | the transistor is neither on, nor off. but somewhere inbetween. | 15:16 |
| ThomasEgi | in most transistor datasheets there are diagrams | 15:16 |
| chris_99 | yup :) | 15:18 |
| ThomasEgi | those can help you to find the BE voltage, but it is roughly 0.6 volt. | 15:18 |
| ThomasEgi | in your case you would want to ahve a look at a diagramm showing the Ube for 2mA collector current. | 15:18 |
| chris_99 | what kind of electronics are you into out of interest? | 15:18 |
| ThomasEgi | all sorts of. | 15:19 |
| ThomasEgi | commercially. i build an sell controlling units, that can be attached to computers via usb | 15:19 |
| ThomasEgi | they are used to turn LED's or small motors on and off. | 15:19 |
| ThomasEgi | usualy at info-panels in exhibitions. | 15:19 |
| ThomasEgi | to indicate where on a map a certain thing is located. | 15:19 |
| chris_99 | ah cool, using a microcontroller? | 15:19 |
| ThomasEgi | yeah | 15:20 |
| chris_99 | nice i've just been playing around with PICs recently, made a GPS clock | 15:20 |
| ThomasEgi | another region of interest of mine is, building free-space optics. | 15:20 |
| ThomasEgi | i am more into ATMEL's product range. mainly due to the good documentation and the nice pipeline under linux | 15:20 |
| chris_99 | i'm using PICs under linux too actually | 15:21 |
| ThomasEgi | so the other interesting thing is sending data around, using a couple of led's lenses and electronics. | 15:21 |
| ThomasEgi | a bit like wlan. but with light instead of wifi-radio | 15:21 |
| ThomasEgi | and . a while ago, i became interested in implants :) | 15:21 |
| chris_99 | tried making one? | 15:22 |
| ThomasEgi | i am still working on my building-blocks. | 15:22 |
| ThomasEgi | i intend to build a set of modules first. which can be easily re-used to build more advanced stuff. | 15:23 |
| ThomasEgi | currently working on subdermal powersupplies, including inductive charging | 15:23 |
| chris_99 | ooh cool :) | 15:23 |
| ThomasEgi | i pretty much finished my tests with magnetometers as sensors. | 15:23 |
| ThomasEgi | next on my list are tests with TI's ADS119x chips | 15:24 |
| chris_99 | i'm curious about nuclear batteries at the moment | 15:24 |
| ThomasEgi | as they would allow to get information out of nerves and muscles. | 15:24 |
| ThomasEgi | and last but not least, i need to get some electrodes and output working | 15:24 |
| ThomasEgi | nuclear batteries? for implants? | 15:24 |
| chris_99 | for all sorts, but yeah you could use them inside the body i guess | 15:25 |
| chris_99 | they used to be used in pacemakers | 15:25 |
| chris_99 | not sure if they still are | 15:25 |
| ThomasEgi | hm... it is true that implants are very low power. at least most of them. | 15:25 |
| ThomasEgi | but from my estimates. most implants i had in mind would run almost 2 weeks on a tiny li-cell that can be recharged in one night | 15:25 |
| ThomasEgi | which would be a good deal, especially since they are cheap and easy to get hands on | 15:26 |
| chris_99 | i wanted to try and buy one of these http://www.citylabs.net/index.php?option=com_content&view=article&id=10&Itemid=25 | 15:26 |
| -!- augur [~augur@208.58.5.87] has quit [Remote host closed the connection] | 15:29 | |
| ThomasEgi | hm. 20 microwatts. | 15:29 |
| ThomasEgi | that would cut it pretty close. | 15:30 |
| chris_99 | i only wanted it to play with really see what i could use it for | 15:31 |
| ThomasEgi | that's sure enough to power a clock. but powering something like an magnetometer, or angular rate sensor would be out of question | 15:31 |
| chris_99 | yeah | 15:31 |
| ThomasEgi | 20 microwatts aint much. you could power a lcd wristwatch with that , i guess | 15:32 |
| ThomasEgi | hm. holds a total of 12kJ energy... | 15:33 |
| ThomasEgi | tiny li-ion battery has like 1.2kJ | 15:34 |
| ThomasEgi | with the advantage of it to be easily rechargeable. | 15:35 |
| ThomasEgi | btw. i just gave the circuit a run. | 15:35 |
| chris_99 | works out well? | 15:37 |
| ThomasEgi | it does work pretty well. unless your head-resistance is too high. in that case, by the ohmian law, there simply is less current flowing than you set. | 15:37 |
| ThomasEgi | but from shorting the electrodes up to several kOhm head-resistance, it keeps the current constant. | 15:38 |
| ThomasEgi | it never exceeds the set current. guess that is the most important part. | 15:39 |
| ThomasEgi | do you have any experience-values for the resistance between the electrodes | 15:39 |
| chris_99 | nah, i've never used electrodes myself | 15:40 |
| ThomasEgi | http://www9.dw-world.de/rtc/infotheque/semiconamps/semiconductor_amps4.html | 15:42 |
| ThomasEgi | chapter 4.2.6 | 15:42 |
| ThomasEgi | a very simple circuit. that can act als constant current source. i pretty much recommend that , additionally | 15:43 |
| ThomasEgi | just for safety in case the transistor breaks due to ,, i dunno, drowning in coke or beer or so | 15:43 |
| ThomasEgi | or... a fuse or so. | 15:45 |
| ThomasEgi | better be safe than sorry | 15:45 |
| ThomasEgi | circuit itself works. but if the parts fail, there is no fallback atm. | 15:45 |

| roksprok | to anyone who is experimenting with tdcs: i have finally gotten my electrodes to work. it is a plastic water bottlecap with a hole in the center, a wire inserted into the hole into a 2in by 2in yellow kitchen sponge. the back of the sponge is layered in duck tape to isolate it from your fingers or whatever you are using to hold it on your head. the conductive solution is a 1:1:.5 ratio of salt: water: flour. use a bunch of salt, my failures turned o | 17:11 |
| roksprok | be due to not enough salt in my saline solution | 17:11 |
| roksprok | connected to a nine-volt this resulted in 7mA of current from one side of my head to the other | 17:12 |
| delinquentme | roksprok, how are you locating this charge? | 17:12 |
| delinquentme | isnt that a key part of the hardware? | 17:12 |
| roksprok | i was doing galvanic vestibular stimulation, so i put one sponge on each mastoid | 17:13 |
| delinquentme | and the sponges sound kinda sketchy for skin contact? | 17:13 |
| roksprok | (the bony part right behind your ear) | 17:13 |
| roksprok | delinquentme: that's why they are soaked in saline, wet sponges are used in a lot of the university research | 17:13 |
| delinquentme | so its supposed to run a small current right through yourcortex? | 17:13 |
| delinquentme | kk | 17:13 |
| delinquentme | i dont know much about this | 17:14 |
| roksprok | i think the one i was doing was interfereing with the balancing stuff in your ear | 17:14 |
| delinquentme | derp wrong term | 17:14 |
| delinquentme | on my part | 17:14 |
| roksprok | because when activated you're pulled towards one side | 17:14 |
| delinquentme | well you use fluid within the ear to balance | 17:14 |
| delinquentme | fluid is probably ionized | 17:15 |
| delinquentme | so that'd make sense | 17:15 |

| roksprok | there is a pic of a university's equpment | 17:15 |
| roksprok | those sponges are made by a medical supply company | 17:15 |
| roksprok | so they work better as far as saltwater dripping down your neck | 17:16 |
| delinquentme | hmm good to know | 17:16 |
| roksprok | i haven't tried actual tdcs, but that seems to be what most people are doing, so i thought i'd include tdcs in there if people are searching the logs for stuff about it | 17:17 |
