bart416 | k, wtf | 04:26 |
---|---|---|
bart416 | according to both satellites and ground based radars I should be in the middle of a severe thunderstorm at this point | 04:26 |
azonenberg | Lol | 04:26 |
azonenberg | But you arent? | 04:26 |
bart416 | No | 04:27 |
bart416 | Slightly clouded | 04:27 |
bart416 | rather sunny for 6:27 in the morning I'd say | 04:27 |
bart416 | Also, vidicon arrived! | 04:28 |
bart416 | And no, not going to make it into an stm :P | 04:31 |
azonenberg | lol | 04:31 |
azonenberg | aww, why not? | 04:34 |
bart416 | Cause it's expensive, still in original factory box, with test certificate and datasheet | 04:35 |
bart416 | lol | 04:35 |
bart416 | If it were to be a "broken" one (generally the screen anyway) I'd do it | 04:37 |
azonenberg | i see | 04:40 |
azonenberg | speaking of which... my new toy has been ordered :) | 04:40 |
azonenberg | http://www.testextra.com/rigol/pages/rigol_ds1102d_mixed_signal_digital_oscilloscope.htm :) | 04:40 |
bart416 | :D | 04:43 |
azonenberg | ships from the manufacturer tomorrow or friday and arrives early next week | 04:44 |
azonenberg | Then i get to play with my FPGA board | 04:44 |
azonenberg | in case you're wondering why my fab stuff isnt going muich this week (besides being busy with work) the guy who runs the SEM lab on campus is on vacation | 04:44 |
azonenberg | and i need his help/approval to run my next experiment | 04:44 |
azonenberg | a) cross section one of my dies and measure layer thickness | 04:44 |
azonenberg | b) see if the evaporator is capable of depositing Ni or Cr | 04:45 |
azonenberg | c) if so, deposit one of them on a <110> sample and see how they work as hardmask | 04:45 |
azonenberg | if my theory is correct i'll be able to use either of the two as a KOH hardmask with no underlying oxide layer | 04:45 |
azonenberg | i'm thinking NiCr 80:20 since i have some 30-gauge of that in stock | 04:46 |
bart416 | azonenberg, http://imageshack.us/photo/my-images/829/imag0437gm.jpg/ | 04:49 |

bart416 | http://imageshack.us/photo/my-images/809/imag0443w.jpg/ | 04:49 |
bart416 | Cr deposition is fairly common I figure | 04:50 |
bart416 | If it doesn't work with a vacuum evaporator you might need to do chemical though | 04:50 |
azonenberg | Shiny | 04:50 |
bart416 | Ni is often done with electroless plating | 04:50 |
azonenberg | And the issue with Cr is that it alloys with the tungsten filament and forms a low-melting-point eutectic | 04:50 |
azonenberg | I need to inquire if there is any problem with doing NiCr deposition from an Al2O3 coated filament | 04:51 |
bart416 | You might have to use another filament | 04:51 |
azonenberg | which i'd purchase and supply | 04:51 |
azonenberg | alumina coated tungsten | 04:51 |
azonenberg | $30 a pop vs $3 | 04:51 |
bart416 | :( | 04:51 |
azonenberg | but for one experiment i can afford it | 04:51 |
azonenberg | they're also theoretically reusable for a couple of depositions | 04:51 |
bart416 | :D | 04:53 |
azonenberg | http://www.tedpella.com/vacuum_html/vac2.htm | 04:55 |
azonenberg | compare part 72-1 ($20.45 for a ten pack) | 04:56 |
azonenberg | to 84-21 ($42.50 each) | 04:56 |
bart416 | Race | 04:56 |
bart416 | Dogs instead of horses | 04:56 |
azonenberg | ? | 04:56 |
bart416 | Jockeys have been replaced with small monkeys | 04:56 |
bart416 | lol | 04:56 |
azonenberg | wrong channel? | 04:56 |
bart416 | http://www.hln.be/hln/nl/959/Bizar/article/detail/1300205/2011/08/02/Vreemdste-race-ooit-hondenrennen-met-apenjockeys.dhtml | 04:57 |
bart416 | Admit, it's awesome in every single way | 04:59 |
bart416 | Also isn't the cost due to the ceramic basket? | 05:02 |
bart416 | I mean, it only seems logical that that is the reason | 05:02 |
bart416 | Except for making the basket yourself I doubt you can do much cheaper | 05:04 |
azonenberg | If its possible for a semi-sane price i plan to buy commercial once | 05:08 |
azonenberg | And only then try and homebrew | 05:08 |
azonenberg | same thing for the evaporator | 05:08 |
azonenberg | It takes variables out of the equation | 05:08 |
azonenberg | compared to say, photomask fab | 05:08 |
azonenberg | which has to be homebrewed due to cost | 05:08 |
bart416 | heh | 05:08 |
bart416 | also, how good is your russian? | 05:35 |

azonenberg | My russian? Zero | 05:51 |
azonenberg | but i have a relative who does german/russian (and i think he's learning swedish) technical translation to english professionally ;) | 05:52 |
azonenberg | he's busy rigth now so i dont think he'll be able to look at it though :( | 05:53 |
bart416 | There we go | 11:24 |
bart416 | another 75 euro in the pocket | 11:24 |
bart416 | EAT THAT CADENCE, lol | 13:00 |
bart416 | OrCADs autorouter said it was impossible | 13:00 |
bart416 | I just did it | 13:00 |
bart416 | lol | 13:00 |
lekernel | what would be great is if some open source router did it :-) | 13:56 |
bart416 | lol | 14:16 |
azonenberg | bart416: how many DRC errors? :P | 14:43 |
bart416 | 40 or so I think | 15:05 |
bart416 | The thing being that its actually making mistakes | 15:05 |
bart416 | It assumes a resistor is a path as well | 15:05 |
azonenberg | lol | 15:05 |
azonenberg | interesting | 15:05 |
bart416 | And that it should be spaced from other paths | 15:05 |
bart416 | Probably some sort of weird setting | 15:06 |
azonenberg | So re the fpga board i'm working on... gonna switch the decoupling caps from 0603 to 0402 | 15:06 |
bart416 | You're nuts! | 15:06 |
bart416 | 0402 = student torturers | 15:07 |
azonenberg | You wnat to see torture parts? :P | 15:07 |
bart416 | I have one that'll beat your fpgas so meh :P | 15:07 |
bart416 | Phonebook sized datasheet, yay! | 15:07 |
azonenberg | how about a 5-ball CSP | 15:08 |
azonenberg | 520 x 570 microns with one in the center | 15:08 |
azonenberg | 200 micron balls | 15:08 |
bart416 | That's doable :P | 15:08 |
azonenberg | well yeah, i did it | 15:08 |
azonenberg | doesnt mean it was easy :p | 15:08 |
azonenberg | i actually had DRC errors on the board to the point the pads shorted with one another lol | 15:09 |
azonenberg | http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301577.JPG | 15:09 |
azonenberg | this was my slasher flick fix :P | 15:09 |
azonenberg | this is 100x magnification http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301579.JPG | 15:09 |
bart416 | lol | 15:09 |
azonenberg | for scale the copper layer is 30um high and the traces are 150 wide | 15:09 |
azonenberg | which means i was making 50-75 micron cuts by hand with a scalpel lol | 15:10 |
azonenberg | under 30x magnification | 15:10 |
azonenberg | My general rule - when the thickness of your traces is a significant fraction (20% or more) of your width | 15:11 |
bart416 | Ever had to solder under a microscope? | 15:11 |
azonenberg | you're doing small scale stuff :P | 15:11 |
azonenberg | Yes | 15:11 |
azonenberg | Rework on an 0.5mm TQFP | 15:11 |
bart416 | 0.5mm you can still do with a headband loupe | 15:11 |
azonenberg | i can solder them w/o mag but trying to tell if you've got the last bit of solder out between the pins is hard | 15:11 |
azonenberg | and since i *have* a stereo microscope i use it sometimes even when not necessary | 15:12 |
azonenberg | my headband magnifier i havent used since getting the scope | 15:12 |
bart416 | headband magnifier is more comfortable | 15:12 |
azonenberg | More? | 15:12 |
bart416 | yeah | 15:12 |
azonenberg | i cant stand 'em, eyestrain up the wazoo | 15:12 |
azonenberg | also - http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301580.JPG | 15:12 |
azonenberg | check that out lol | 15:12 |
bart416 | heh, depends on if you already wear glasses or not | 15:12 |
azonenberg | 400x | 15:12 |
azonenberg | depth of field is less than the thickness of metal lol | 15:12 |
bart416 | that's why you use a headband loupe :P | 15:14 |
bart416 | Just get a good one | 15:14 |
bart416 | I can't stand the ones at college so bought my own | 15:14 |
bart416 | additionally mine has a leather strap, not a plastic one like theirs | 15:14 |
azonenberg | mine is leather | 15:15 |
azonenberg | or at least looks leathery | 15:15 |
azonenberg | prob synthetic | 15:15 |
bart416 | heh | 15:15 |
bart416 | + several lenses | 15:16 |
azonenberg | ah | 15:16 |
azonenberg | mine has all plastic optics :P | 15:16 |
azonenberg | one primary, flip down over both eyes, and then a single flip down over the left eye over that | 15:16 |
bart416 | Mine is CR 39 just like my regular glasses | 15:16 |
azonenberg | i see | 15:17 |
azonenberg | also - http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301584.JPG | 15:17 |
azonenberg | the CSP breakout cooking in my toaster oven / IR reflow oven lol | 15:17 |
bart416 | heh | 15:17 |
azonenberg | And yes that "cookie sheet" is a 4-inch wafer | 15:17 |
azonenberg | i have plenty of extra cheap ones and they're pretty inert, so... | 15:18 |
bart416 | lol | 15:18 |
bart416 | I use a regular oven tray | 15:19 |
azonenberg | http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301588.JPG | 15:21 |
azonenberg | finished bga :) | 15:21 |
azonenberg | http://colossus.cs.rpi.edu/pictures/2011/August/8-1-2011%20-%20CSP/S7301590.JPG | 15:21 |
bart416 | heh | 15:25 |
bart416 | You're nuts and need another hobby :P | 15:26 |
bart416 | Ever considered driving cars off a cliff and jumping out with a parachute? | 15:29 |
azonenberg | Nope | 15:30 |
bart416 | uhm other ideas? | 15:46 |
bart416 | Did you ever build rockets? | 15:46 |
azonenberg | Tiny little ones yeah | 15:46 |
azonenberg | nothing big, like orbital grade | 15:46 |
azonenberg | though thats on the world domination TODO list | 15:46 |
bart416 | What altitude have you achieved? | 15:48 |
bart416 | Or did you go for distance? | 15:48 |
azonenberg | altitude, and only like 500ft | 15:49 |
azonenberg | i was like 12 at the time | 15:49 |
azonenberg | And used prebuilt motors | 15:49 |
bart416 | aaaaaw :( | 15:49 |
bart416 | Wanna borrow my LOX canister? :P | 15:49 |
azonenberg | Lol | 15:49 |
bart416 | And own made graphite nozzles? | 15:49 |
bart416 | *home | 15:49 |
azonenberg | actually the compressed gases i want most now are N2 and Ar | 15:49 |
bart416 | well not really home but DIY | 15:49 |
bart416 | N2 is easy enough | 15:49 |
azonenberg | for general purpose drying and sputtering respectively | 15:50 |
bart416 | Ar is more problematic | 15:50 |
azonenberg | dry dust-free N2 no less | 15:50 |
bart416 | Mhhh | 15:50 |
azonenberg | the Ar also needs to be high grade | 15:50 |
azonenberg | prob from a welding supplier | 15:50 |
bart416 | Tried diving stores? | 15:50 |
azonenberg | i havent looked yet | 15:50 |
bart416 | Divers sometimes also need pure nitrogen | 15:50 |
azonenberg | other stuff is higher priority | 15:50 |
bart416 | Most places that compress LOX also sell high grade N2 | 15:51 |
azonenberg | i see | 15:51 |
bart416 | It's easier to get liquid nitrogen than LOX | 15:52 |
azonenberg | yeah | 15:52 |
azonenberg | But i'd want gaseous at first | 15:52 |
azonenberg | LN2 is on the wish list for longer term | 15:52 |
azonenberg | when i actually have gear that can use it | 15:53 |
bart416 | You could get dry N2 from LN2 though | 15:53 |
azonenberg | But LN2 has a comparatively short shelf life | 15:53 |
bart416 | True | 15:53 |
azonenberg | compressed N2 can be stored for a long time afaik | 15:53 |
bart416 | I've never had to store it long, rockets you know :P | 15:53 |
azonenberg | since its room temp and high pressure | 15:53 |
azonenberg | and i was planning to set up some N2 guns i could use around the lab | 15:54 |
azonenberg | for drying stuff etc | 15:54 |
azonenberg | So it'd be a little bit here and there over a really long time | 15:54 |
azonenberg | months to years | 15:54 |
bart416 | Probably | 15:54 |
azonenberg | i'd probably go for a diving sized cylinder (rather than the giant 5-foot ones) | 15:54 |
azonenberg | and i'td last me a long time | 15:54 |
bart416 | Don't you also need oxygen to make good quality oxide layers? | 15:55 |
azonenberg | I was actually planning to do oxidation in air | 15:55 |
bart416 | compressed oxygen is fairly common | 15:55 |
bart416 | even if it's not highest purity | 15:55 |
azonenberg | Again, the question is not what i can get | 15:55 |
azonenberg | its what i need | 15:56 |
bart416 | It's not that expensive | 15:56 |
bart416 | Just saying, you could get it :P | 15:56 |
azonenberg | its not just cost, its the space in my lab, safety issues, etc | 15:56 |
bart416 | heh, I'd be more worried about the compressed nitrogen than oxygen | 15:57 |
azonenberg | I wouldnt have a lot of it though | 15:57 |
azonenberg | like maybe a 50ft^3 bottle | 15:57 |
bart416 | how much liter is that? | 15:57 |
azonenberg | same with the Ar | 15:57 |
azonenberg | exact amount is irrelevant | 15:57 |
azonenberg | point is, we're talking lecture bottle sized | 15:57 |
azonenberg | maybe about the size of a medical O2 canister | 15:58 |
bart416 | so small reserve diving bottle size? | 15:58 |
bart416 | small, medium or large medical O2 canister? | 15:58 |
azonenberg | medium ish? | 15:58 |
bart416 | mhhh | 15:58 |
azonenberg | iow, a size such that the risk of suffocation or overpressure damage is minimal | 15:58 |
bart416 | just be sure you can ventilate the area well | 15:58 |
azonenberg | even in case of an uncontrolled release | 15:58 |
azonenberg | And thats one of the reasons i havent actually gotten it yet | 15:58 |
azonenberg | i havent done a full survey of the area yet to decide if its possible to do so safely | 15:59 |
bart416 | We use those medium size bottles with the red cross on events | 15:59 |
bart416 | They put an emergency over pressure release on them to outside the ambulance | 15:59 |
azonenberg | I wont be using anything toxic, so there is no concern about trace leakage | 15:59 |
bart416 | Yeah, but just safety | 16:00 |
azonenberg | They'd obviously be chained down | 16:00 |
bart416 | Heh, chains don't help if these things launch themselves | 16:00 |
Action: azonenberg would rather not have flying cylinders going torpedo on him | 16:00 | |
azonenberg | and of course they'd have overpressure releases | 16:00 |
bart416 | yeah, but make sure they go outside | 16:00 |
azonenberg | you mean to avoid blowing the windows etc? | 16:00 |
bart416 | no | 16:00 |
bart416 | to avoid venting it in your own space | 16:01 |
azonenberg | Depends on what the gas is | 16:01 |
azonenberg | O2 i wouldnt mind venting a small amount but inert stuff i'd be more cautious about | 16:01 |
azonenberg | Depends also on the overall volu\me of the tank | 16:01 |
bart416 | I'd be more worried about the N2 | 16:01 |
azonenberg | if its 0.5% of the room's volume, a few cubic feet, it doesnt matter much | 16:01 |
azonenberg | if its a quarter, it matters a lot | 16:01 |
bart416 | We get O2 leaks all the time in our ambulance | 16:01 |
bart416 | Just makes you a little light headed | 16:01 |
azonenberg | the Ar would probably be only say a 10 ft^3 bottle | 16:02 |
azonenberg | since i'd be using it at low pressure for sputtering | 16:02 |
azonenberg | so say a 20 x 10 ft^2 room is 200ft^2, times 10 foot ceilings (rough numbers, havent measured) is 2,000 ft^3 | 16:02 |
bart416 | But they still bothered to make the safety release go outside | 16:02 |
azonenberg | say 20ft^3 for the Ar | 16:02 |
bart416 | It's 1m extra of tubing | 16:03 |
azonenberg | So 1% | 16:03 |
azonenberg | But yeah, if i set it up i'd probably do that anyway | 16:03 |
azonenberg | there are people on campus who know all of the codes | 16:03 |
azonenberg | i'm sure i could ask one | 16:03 |
bart416 | Also while I'm at it, volunteer for your local red cross!!!!!!!!!!!!!!!!!!!!!! | 16:03 |
bart416 | btw azonenberg screen of a vidicon: https://lh6.googleusercontent.com/-OZz9JDSDhDk/Tjq_VNdzd4I/AAAAAAAAAGc/B33vKOdozCk/s800/IMAG0468.jpg | 16:15 |
bart416 | This looks about as clean as a wafer o_O | 16:15 |
azonenberg | whats the dartk area in the middle? | 16:16 |
bart416 | That's the window | 16:16 |
bart416 | screen | 16:16 |
bart416 | hard to really name it | 16:16 |
azonenberg | no, i mean there's a rectangular area | 16:16 |
azonenberg | is that an edit to the photo or something? | 16:16 |
azonenberg | as well as what looks like some text on the right side | 16:17 |
bart416 | ah, you're seeing the reflection of my phone | 16:17 |
bart416 | lol | 16:17 |
azonenberg | oh lol | 16:18 |
bart416 | The text you're seeing is htc :P | 16:18 |
azonenberg | Makes sense now lol | 16:18 |
azonenberg | and yeah, thats shiny lol | 16:18 |
bart416 | But the material is a highsly sensitive photoconductor | 16:18 |
azonenberg | what are you gonna use it for? | 16:18 |
bart416 | I'm going to build a B/W camera | 16:18 |
bart416 | And later I might use it as detector in a SEM | 16:19 |
bart416 | This thing is horribly sensitive to radiation heh | 16:19 |
bart416 | And already works by electronics | 16:19 |
azonenberg | i see | 16:19 |
bart416 | *electrons | 16:20 |
bart416 | bah | 16:20 |
bart416 | lack of sleep the past few weeks is doing something to me | 16:20 |
azonenberg | Its overkill thouhg, for an ET detector you dont need pixels | 16:20 |
azonenberg | just a block of phosphor | 16:20 |
azonenberg | and a photomultiplier | 16:20 |
bart416 | yeah, but you must remember, this thing in theory has infinite horizontal resolution :P | 16:20 |
azonenberg | lol | 16:21 |
azonenberg | i'm saying, using it as an SE detector is a waste | 16:21 |
bart416 | Dunno | 16:21 |
azonenberg | since you dont need position | 16:21 |
azonenberg | you get position by knowing where the beam is pointed | 16:21 |
bart416 | Maybe an alternative design | 16:21 |
bart416 | Using multiple beams | 16:22 |
azonenberg | all you need to know is how strong the SE emission is | 16:22 |
azonenberg | and hmm, maybe... | 16:22 |
bart416 | That could be interesting | 16:22 |
bart416 | Higher speed and power | 16:22 |
azonenberg | that means multiple guns though | 16:22 |
bart416 | Maybe you could then use one beam for electron cutting and a few others to image what you're doing at the same time | 16:23 |
azonenberg | its enough of a PITA to align and stigmate one | 16:23 |
bart416 | Heh | 16:23 |
bart416 | I need more to plead insanity if they ever figure out what you're doing | 16:23 |
bart416 | They'll consider me sane due to you! | 16:24 |
azonenberg | lol | 16:25 |
azonenberg | hey, i'm not the one building a nuclear reactor in his kitchen | 16:25 |
azonenberg | also, my lab is well organized and almost spotless | 16:25 |
azonenberg | that nutjob had no sense of lab hygiene | 16:26 |
bart416 | That nutjob was an idiot | 16:26 |
bart416 | he should be happy they caught him | 16:26 |
azonenberg | no | 16:26 |
azonenberg | his *neighbors* should be :P | 16:26 |
bart416 | It's a small wonder he doesn't have radiation sickness yet | 16:26 |
azonenberg | you sure he doesnt? :p | 16:28 |
bart416 | I hope for him not | 16:34 |
bart416 | lol, a friend just called | 16:34 |
bart416 | Microwave accident | 16:35 |
bart416 | lol | 16:35 |
azonenberg | lol | 16:35 |
azonenberg | as in? | 16:35 |
bart416 | You know that quick microwave rice | 16:35 |
bart416 | 45 seconds... | 16:35 |
azonenberg | yeah? | 16:35 |
bart416 | The packs often say "put it in the microwave 0:45" | 16:35 |
bart416 | Well, she did | 16:35 |
azonenberg | 45 minuts | 16:35 |
bart416 | 45 minutes | 16:35 |
bart416 | lol | 16:35 |
azonenberg | lol | 16:35 |
azonenberg | the result? | 16:35 |
bart416 | She didn't want to tell | 16:36 |
bart416 | lol | 16:36 |
bart416 | I'll poke for the result later | 16:36 |
bart416 | She's lucky I always make food for one person extra :| | 16:36 |
azonenberg | molten plastic all over the inside of the microwave, smoke filling the room? | 16:36 |
bart416 | I figure | 16:36 |
bart416 | Wouldn't be the first time that has happened with her | 16:36 |
bart416 | Nice person, just sort of uhm, clumsy | 16:36 |
bart416 | Does mean I have to clean up this mess a bit | 16:37 |
bart416 | good uhm noon over there I guess? | 16:37 |
azonenberg | lol | 16:37 |
azonenberg | almost 1300, but yeah | 16:37 |
azonenberg | what time is it over by you again? | 16:38 |
bart416 | 18:38 | 16:38 |
bart416 | There we go | 16:41 |
bart416 | clean | 16:41 |
bart416 | lol | 16:41 |
azonenberg | lol | 16:41 |
bart416 | and food in the oven | 16:41 |
bart416 | that went faster than expected o_O | 16:41 |
azonenberg | Also - http://i.imgur.com/ho9LT.png | 16:41 |
azonenberg | Front view of one of my other side projects | 16:42 |
azonenberg | look familiar? | 16:42 |
azonenberg | I still have a bit more CAD to do and then a board to design / firmware to write | 16:42 |
bart416 | Portal? :P | 16:42 |
azonenberg | Yep | 16:42 |
bart416 | Evil :P | 16:42 |
azonenberg | Life sided replica | 16:42 |
azonenberg | armed with twin rubber band guns | 16:42 |
bart416 | You using inventor studio for animation? | 16:42 |
azonenberg | webcam based target tracking in rev 1 (PC app), rev 2 will use an NTSC camera, ADC, and FPGA | 16:43 |
azonenberg | no animation, just CAD | 16:43 |
azonenberg | gonna prob be CNCing some of the parts | 16:43 |
bart416 | lol | 16:43 |
azonenberg | there's a con on campus some time in the early spring | 16:44 |
azonenberg | i'm thinking of bringing it there and setting it up to take potshots at the furries :P | 16:44 |
azonenberg | As well as to get reactions from generic geeks on it | 16:44 |
bart416 | bah, you have furries on campus? | 16:47 |
bart416 | Also, I have an idea to beat your insanity | 16:50 |
bart416 | Going to build a time machine | 16:51 |
bart416 | AND bring Tesla to the modern age | 16:51 |
bart416 | And give him unlimited resources to build destructive weapons | 16:51 |
bart416 | muahahahahahhahahahaaaaaa | 16:51 |
azonenberg | Well, there's at least one furry among the student body | 16:52 |
azonenberg | i used to see him in the dining hall most days around lunchtime | 16:52 |
azonenberg | you could tell because his laptop had little furry ears sticking off the corners of the screen | 16:52 |
azonenberg | and the power cord was wrapped in fur so it looked like a tail | 16:52 |
bart416 | oh gosh :| | 16:52 |
bart416 | My hate for furries increased significantly when I saw two of them "yiffing" in public in a train station | 16:53 |
azonenberg | And while the con is a general "everything geeky" con, furries are among the many attendies | 16:53 |
bart416 | + the fact that they're major headaches on irc for admins | 16:53 |
azonenberg | attendees* | 16:53 |
azonenberg | only maybe 1% though | 16:53 |
bart416 | Heh | 16:54 |
bart416 | Make an automatic fur detector | 16:54 |
bart416 | And shoot at their costumes with H202 | 16:54 |
bart416 | :P | 16:54 |
azonenberg | lol | 16:54 |
azonenberg | i dont want to oxidize them... | 16:54 |
azonenberg | But a fur detector would be an interesting vision problem lol | 16:55 |
bart416 | nah, if it's 3% it'll only bleach their clothing | 16:55 |
azonenberg | And the guy i'm talking about doesnt have a full fursuit | 16:55 |
azonenberg | I did almost trip over his tail once though | 16:55 |
azonenberg | was heading down to the electronics club the weekend of the con a year or two ago | 16:56 |
bart416 | But you have nice conventions like that | 16:56 |
bart416 | We don't :( | 16:56 |
bart416 | I should ask to organize one | 16:57 |
bart416 | What sorts of stuff do you have at that convention? | 16:58 |
azonenberg | No idea, never actually attended | 16:58 |
azonenberg | lol | 16:58 |
azonenberg | This is the first project i've worked on i thought would be appropriate | 16:58 |
bart416 | lol | 16:58 |
azonenberg | http://genericon.union.rpi.edu/ | 16:58 |
bart416 | Bah, that's just a weaboo convention | 17:01 |
azonenberg | Like i said, i've never actually attended | 17:01 |
azonenberg | But based on photos i've seen i think this would go over well lol | 17:01 |
bart416 | Meh, not worth organizing a weaboo convention though :P | 17:02 |
azonenberg | lol | 17:02 |
bart416 | 1) "OMG ASIAN" is annoying | 17:02 |
bart416 | 2) see 1 | 17:02 |
bart416 | 3) They're cowards generally | 17:03 |
bart416 | 4) Electronics and funny projects > Anime | 17:03 |
azonenberg | from what i understand the percentage of anime stuff there is actually not that high | 17:03 |
azonenberg | from the name you can tell that they try to cater to any and all geeky interests | 17:03 |
azonenberg | ranging from anime to scifi to fur to RPGs | 17:03 |
bart416 | The issue is that you might attract the makerfair and arduino idiots with that though! | 17:06 |
azonenberg | Lol, yes there are a lot of arduino fans around campus | 17:06 |
Action: azonenberg rages | 17:06 | |
azonenberg | A few of the makerfaire projects are actually good | 17:07 |
azonenberg | i saw a nice tesla coil vid | 17:07 |
bart416 | some | 17:07 |
bart416 | but most are just copy and paste of the internet | 17:07 |
azonenberg | lol yeah | 17:08 |
XgF | Nothing wrong with the Arduino for its intended purpose. Just a shame its become used for so much more | 17:08 |
bart416 | Arduino makes people lazy and stupid | 17:08 |
bart416 | Where are the days of messing on a breadboard with a pile of wires, passives and some transistors to program an 8051 microcontroller? | 17:08 |
azonenberg | http://colossus.cs.rpi.edu/pictures/2011/July/7-26-2011%20-%20lab/S7301572.JPG << my idea of a breadboard | 17:09 |
azonenberg | running both JTAG and USB onto it :P | 17:09 |
azonenberg | and equipped with a 32-bit MCU and a CPLD lol | 17:09 |
bart416 | lol | 17:09 |
azonenberg | And all of the breakouts are full custom | 17:10 |
bart416 | My breadboard is still half fried from an xray transformer :D | 17:10 |
bart416 | And another one has a huce motorolla cpu on it | 17:10 |
azonenberg | hasnt anyone ever told you breadboards arent good for HV or sensitive analog? :P | 17:10 |
azonenberg | waaay too much capacitive coupling between adjacent rails | 17:10 |
bart416 | (m68k) | 17:10 |
azonenberg | the rpi e-club has some 68ks | 17:10 |
azonenberg | they're like 60 pin DIP | 17:11 |
bart416 | Hey, it wasn't my fault that the mosfet failed! | 17:11 |
azonenberg | CDIP i think | 17:11 |
bart416 | *huge | 17:11 |
bart416 | Heh, I pulled one of those out of an old sharp laser printer :D | 17:11 |
bart416 | And enough 7400 series logic for the rest of my life >_> | 17:12 |
bart416 | And she's late >_> | 17:13 |
bart416 | back | 17:29 |
bart416 | Sort of dissapointed | 17:35 |
bart416 | At least expected her to stick around for a while | 17:35 |
azonenberg | lol | 17:36 |
azonenberg | she just ate and left? | 17:36 |
bart416 | Yes | 17:40 |
bart416 | Why do I still bother to help her? | 17:40 |
bart416 | Except the fact that I might sort of like her | 17:40 |
bart416 | Oh yeah, worst side bonus | 17:42 |
azonenberg | Lol | 17:42 |
bart416 | Her boyfriend picked her up | 17:42 |
bart416 | So it's not really ammusing | 17:42 |
bart416 | Didn't know that part yet | 17:42 |
azonenberg | I see :p | 17:42 |
bart416 | I don't really think it's still funny at this point actually but yeah | 17:42 |
azonenberg | no, i'm just amused in general at the antics of geeks attempting to attract the attention of female H. Sapiens | 17:44 |
azonenberg | And at the numerous ways they tend to fail | 17:44 |
azonenberg | Especially if compltely unpredictable | 17:45 |
bart416 | Keep in mind her probably asshole boyfriend (if he's anything like the previous ones) couldn't even bother to make her anything to eat | 17:45 |
azonenberg | ouch | 17:45 |
bart416 | The past 5 years I've taken better care of her than her own damn family at times... | 17:45 |
bart416 | And she knows I like her | 17:46 |
bart416 | So yeah, just going to give up | 17:46 |
bart416 | This isn't worth it | 17:46 |
azonenberg | The last girl i had over my lab, well... | 17:46 |
azonenberg | she was an RPG fanatic | 17:46 |
bart416 | ... | 17:46 |
azonenberg | Between that and her not being a supergeek like me (i.e .actually needing to study) we saw each other IRL twice over the course of a semester lol | 17:47 |
azonenberg | she was cute but we never ended up actually dating | 17:48 |
azonenberg | And that wont happen any time in the near future considering my school ended up being too expensive and she transferred out :P | 17:48 |
bart416 | :( | 17:48 |
azonenberg | So yeah, locating females of the right type at engineering schools isnt easy | 17:51 |
bart416 | Yeah | 17:53 |
bart416 | Strictly speaking, most are ugly | 17:53 |
bart416 | so that limits the acceptable options | 17:53 |
azonenberg | Lol | 17:53 |
bart416 | And why are it always the fat ugly ones that wear skirts/shorts/expose flesh | 17:54 |
bart416 | aaaaaaaaargh | 17:54 |
azonenberg | well the bigger problem is, most people (regardless of gender) are boring | 17:54 |
azonenberg | even at engineering schools, where there's a higher percentage of nerds | 17:54 |
azonenberg | it's maybe 20% vs 2% | 17:54 |
bart416 | I don't find that too problematic if I don't have to stay with people too long | 17:58 |
azonenberg | idk, i cant really stand hanging out with boring people | 17:59 |
azonenberg | it's... boring | 17:59 |
bart416 | They probably say the same about you | 17:59 |
azonenberg | lol | 17:59 |
bart416 | You just sort of need a trigger to switch to casual conversation with a common subject | 18:00 |
azonenberg | thats the point - "common subject" | 18:00 |
azonenberg | with me and 95% of people there isnt one lol | 18:00 |
bart416 | That you can fix you know :P | 18:01 |
azonenberg | you mean studying popular culture? | 18:01 |
bart416 | nah | 18:01 |
bart416 | Don't you watch some sports | 18:01 |
azonenberg | No thanks, i prefer culture to stay in my petri dishes where it belongs :P | 18:01 |
bart416 | Or do some sports? | 18:01 |
azonenberg | and nope | 18:01 |
bart416 | Watch some movies? | 18:01 |
bart416 | Read (comic) books? | 18:01 |
bart416 | Listen to music | 18:01 |
azonenberg | my exercise of choice is out in the mountains, 10+ miles from the nearest town, and with a 30 pound pack on my back | 18:01 |
bart416 | Go to concert or events | 18:02 |
azonenberg | and those other subjects are really pretty boring to someone like me | 18:02 |
bart416 | You'd be amazed how many people are willing to talk about such things :P | 18:02 |
azonenberg | my brain cant stand downtime | 18:02 |
bart416 | How do you do it? | 18:02 |
azonenberg | i was on a family vacation in june after graduating | 18:02 |
azonenberg | after the first day or two i pulled out my laptop and started writing a paper | 18:02 |
azonenberg | the relaxation was driving me nuts | 18:02 |
bart416 | o_O | 18:02 |
bart416 | You need some time off, or you have a burnout eventually | 18:03 |
azonenberg | you misunderstand lol | 18:03 |
azonenberg | time off from coding at work | 18:03 |
azonenberg | is chip fab at home | 18:03 |
azonenberg | when i get tired of that i do FPGA stuff | 18:03 |
bart416 | o_O | 18:03 |
azonenberg | as long as i set Tq short enough and use a prioritized round robin scheduler... | 18:04 |
azonenberg | i was homeschooled, remember... i grew up in relative social isolation (church and scouts, each once a week, were my only real contact with the outside world) | 18:04 |
bart416 | My time off: running, sailing, shooting bottles, watching movies, playing guitar or piano, cooking, going for a drink with some friends, ... | 18:04 |
azonenberg | spent most of the day reading and studying because that's all there wasto do | 18:04 |
bart416 | I had neither of those | 18:05 |
azonenberg | And now i'm so used to that lifestyle i cant handle anything else lol | 18:05 |
azonenberg | my mom forced me to play the piano (piano teacher) for many years | 18:05 |
bart416 | My only real extensive social contact was a single person | 18:05 |
azonenberg | i quit the second i moved out | 18:05 |
bart416 | I hated playing piano at the time | 18:05 |
bart416 | Now I love it | 18:05 |
azonenberg | Lol | 18:05 |
azonenberg | I bet her $100 when i was around 12 that she was wrong | 18:05 |
azonenberg | and i wouldn't love playing by my 18th birthday | 18:06 |
azonenberg | i collected | 18:06 |
azonenberg | and havent touched a piano since | 18:06 |
bart416 | You can feel the flow of the music, the subtle tones of the hammers hitting the snares, ... | 18:06 |
bart416 | Piano is such an excellent instrument | 18:06 |
azonenberg | i like listening to it | 18:06 |
azonenberg | But i'd do anything to not be the guy sitting at it | 18:06 |
bart416 | Piano is one of the few instruments you can really play on feeling | 18:07 |
bart416 | Guitar you need to study | 18:07 |
bart416 | Piano you start out by studying but after a few years you can just play what you have in your head | 18:07 |
bart416 | That's why it's such a great instrument | 18:07 |
azonenberg | When i quit i was able to play almost the entire third (? slow one, whichever that is) movement of the moonlight sonata from memory | 18:08 |
azonenberg | i could do about the first half of it with my eyes shut before hitting a part with difficult fingering | 18:08 |
bart416 | Heh, I don't look at the keyboard anymore at all | 18:08 |
bart416 | For anything | 18:08 |
bart416 | Only at the start to position my hands | 18:08 |
azonenberg | That was one spot where i had to move my hand an octave or two over | 18:09 |
azonenberg | couldnt get it exact without looking | 18:09 |
azonenberg | Anyway so point is, as a result of growing up like that | 18:09 |
bart416 | You know what's actually supprisingly hard, playing mozart's turkish march at full speed | 18:09 |
azonenberg | i'm now so conditioned into spending all of my waking hours on scientific / academic subjects | 18:10 |
azonenberg | that i now do it by choice | 18:10 |
bart416 | I sort of became like that when my girlfriend left, it's fixing itself now though | 18:10 |
bart416 | You just need a reason to get out of the pattern | 18:10 |
bart416 | (Also I meant turkish march is hard to play for a young person with smaller hands eh) | 18:10 |
azonenberg | thats the thing, i dont want to get out of it | 18:11 |
azonenberg | it's made me who i am | 18:11 |
bart416 | Sometimes to meet a person you want to meet you have to get out of it though | 18:11 |
bart416 | That's the main reason to get out of your habbits | 18:11 |
azonenberg | i'd rather take my time and find someone who can put up with me like this :P | 18:12 |
azonenberg | i dont want to take the risk of getting distracted and losing my edge | 18:12 |
bart416 | Actually, in my case it improves my academic performance | 18:12 |
bart416 | To give you an idea, last year I had a sort of relationship with a girl that I shared several classes with | 18:13 |
bart416 | So yeah, during math | 18:13 |
bart416 | Solving differential equations | 18:13 |
bart416 | I actually managed to beat a professor >_> | 18:13 |
azonenberg | lol | 18:13 |
bart416 | Normally I'd take twice as long as him | 18:14 |
bart416 | Just her being there was enough to convince me to just go for it | 18:14 |
azonenberg | Guess it depends on the situation then - but i usually find that my inherent motivation to get out there and be the best of the best is all it takes | 18:15 |
azonenberg | anything else just is a distraction | 18:15 |
bart416 | Not all distractions are bad | 18:16 |
bart416 | I didn't pay attention at all in classes I shared with her, yet I had excellent grades on every single one of them; and they weren't exactly easy | 18:16 |
bart416 | Simply being happy seemed to do the trick :S | 18:16 |
azonenberg | i see... in my case, talking to this girl ended up giving me an alternative to working on HW for my least interesting class of the semester | 18:17 |
azonenberg | Which, as you can imagine, didnt bode well for my grade | 18:17 |
azonenberg | forget what i got but it was my worst grade in my entire period as an undergrad | 18:17 |
azonenberg | b- maybe? | 18:17 |
bart416 | b- is how much %? | 18:18 |
azonenberg | C actually | 18:18 |
azonenberg | and i dont know, the class was curved | 18:18 |
azonenberg | but it brought my 3.85 down to a 3.76 | 18:18 |
azonenberg | By comparison first semester freshman year, when i was a hermit who spent most of his time in the dorm | 18:19 |
azonenberg | i had a 3.93 | 18:19 |
azonenberg | one A- and all As otherwise | 18:19 |
bart416 | If they bothered to grade on curve I'd get A on everything as well >_> | 18:20 |
azonenberg | In any case, i got my degree so that's over with | 18:21 |
azonenberg | But now i have a phd to do | 18:21 |
berndj | you guys should apply the scientific method to girls! bring your hacking skills to bear on the problem | 21:06 |
berndj | bart416, did you get any info on diy multilayer boarding? | 21:08 |
azonenberg | berndj: lol | 21:08 |
bart416 | berndj, no | 21:08 |
bart416 | When would I have done that | 21:08 |
bart416 | All I got was a name that I forgot | 21:08 |
azonenberg | i *did* remember doing a chi-square analysis to determine whether me and a girl i was hanging out with were dating or not lol | 21:08 |
bart416 | o_O | 21:08 |
azonenberg | the result was - not enough data to confirm or deny a statistically significant correlation | 21:09 |
berndj | dj delorie / www.delorie.com. i think he does some sort of heat fusion of layers | 21:09 |
bart416 | berndj, applying engineering skills to social issues leads to bad situations | 21:09 |
berndj | depends how meta you go | 21:10 |
bart416 | his site doesn't seem to show much | 21:11 |
berndj | but i remember the pua guys taking the hypothesis/experiment/measure process quite seriously. sometimes quite comically | 21:11 |
berndj | yeah, mostly pics of what is, not much on the how | 21:11 |
bart416 | useless | 21:14 |
