| fenn | is that a sanrio thing? | 00:05 |
|---|---|---|
| fenn | like hello kitty | 00:05 |
| bkero | Domo-kun | 00:06 |
| bkero | Yea | 00:06 |
| bkero | and that's 7-11's new ad campaign | 00:06 |
| fenn | let's put it this way.. would you be aghast if Target suddenly had a hello kitty ad campaign? | 00:07 |
| bkero | Target used Domo-kun as their 2008 Halloween ad campaign. | 00:08 |
| fenn | hah | 00:09 |
| fenn | i finally figured out wtf was with the banner on ACTLAB http://www.tarvu.com/ | 00:19 |
| drazak | so uh | 00:33 |
| drazak | if we have a big bunch of shipping containers | 00:34 |
| drazak | will there be room for a ceramic shipping conainer? | 00:34 |
| drazak | (aka one for ceramics, instead of science :P) | 00:34 |
| fenn | that's the neat thing about shipping containers.. they're easy to add on incrementally | 00:36 |
| ybit | ...if you have a crane or cherry picker | 00:36 |
| fenn | well i think a semi truck would be more appropriate | 00:39 |
| ybit | and just how do you plan on getting the container into and out of this truck? :) | 00:40 |
| drazak | we could sell pottery and artwork to make money | 00:41 |
| drazak | :P | 00:41 |
| fenn | it sits on the back, you attach a little pair of wheels to the back | 00:41 |
| fenn | drazak: yeah sell all the fuckups as "artwork" :0 | 00:42 |
| drazak | like, 500 pounds of dry clay is almost 2000 pounds of wet clay or something like that | 00:42 |
| drazak | and 500 pounds of wet clay is like | 00:42 |
| drazak | er, dry clay | 00:42 |
| drazak | is like 120$ | 00:42 |
| drazak | say the average weight of a piece of pottery is a 1/2lb dry clay | 00:43 |
| drazak | and it costs a buck on average to glaze the piece | 00:43 |
| drazak | and you sell it at 15 bucks a piece, that's 13$ profit a piece | 00:44 |
| drazak | with 1 person working 6-8 hours doing pottery you can produce on average 20 pieces a day | 00:44 |
| drazak | that's 260 a day pure profit | 00:44 |
| ybit | i'm going back and forth on continuing ahead with plans to build a lab here or finishing school @ upc in barcelona and creating one there, right now it's a matter of cost and how quickly i can get my equipment and a secure place to use it. | 00:45 |
| drazak | 6 or 7 potters working 4 hours a day (aka doing science the rest) make almost a grand a day | 00:45 |
| drazak | I can't think of many labs that go through a grand of supplies in a day | 00:46 |
| drazak | well, some have expensive things that are much less than a grand over the spread of a few days | 00:46 |
| * ybit figures it's to get 4k+ easily in profit from selling small electric cars and especially wranglers from the junkyard | 00:46 | |
| ybit | +possible | 00:47 |
| drazak | a day? | 00:47 |
| drazak | a week? | 00:47 |
| drazak | a month? | 00:47 |
| drazak | a year? | 00:47 |
| ybit | on each vehicle | 00:47 |
| fenn | drazak how are you going to sell that much "art" | 00:47 |
| drazak | and how long does each vehicle take? | 00:47 |
| ybit | i _might_ be able to get 4 cars a year | 00:47 |
| ybit | that's very optimistic | 00:47 |
| fenn | or you might find yourself totally swamped with orders | 00:47 |
| fenn | and no way to increase production | 00:48 |
| ybit | i figured it would be a good way to make quick cash and continue on with my education elsewhere | 00:48 |
| ybit | well, i don't really care for the university, but i do want to get away for awhile | 00:48 |
| drazak | fenn: a store, the internet, etc, large order, but there's also the whole handmade set things where you make a little less profit but it's a whle set throw in a couple hours, trimmed in another hour over the next two days, and then fired+glazed over the next few in a total of actual work of an hour | 00:48 |
| ybit | it would be nice to work in upc's neuroeng lab for a bit | 00:49 |
| drazak | a set of 3 handmade bowls sells for 60$ | 00:49 |
| drazak | each bowl is tinyass | 00:49 |
| drazak | it's an alternative way to support a lab | 00:51 |
| ybit | not sure if i'll be be coming back to live here, which is why i'm highly considering holding off on building just yet, and using some money on acquiring equipment | 00:51 |
| drazak | pottery and/or grants and/or welding and/or woodwork and/or electric cars and/or whatever stuff like that | 00:51 |
| drazak | anyway I'm going to bed | 00:52 |
| ybit | gn drazak | 00:52 |
| drazak | I think | 00:52 |
| ybit | hehe | 00:52 |
| ybit | what i had in mind was to setup a lab and a hackerspace | 00:53 |
| ybit | both are seperate NPOs, hspace classified as educational and the other as scientific. | 00:53 |
| drazak | well, even the lab I work at the PI has a side business | 00:54 |
| drazak | that he runs out of the lab | 00:54 |
| ybit | put half the property in each other's name so that one doesn't rely on the other, but are both mutually beneficial | 00:54 |
| ybit | the lab would obviously go after grants | 00:54 |
| ybit | while the hackerspace sufficed with donations/membership dues | 00:55 |
| drazak | for our lab | 00:55 |
| fenn | membership dues are not enough to run a space | 00:55 |
| ybit | $30 | 00:56 |
| ybit | and if you have ~15, you should be okay | 00:56 |
| ybit | this is assuming you aren't renting | 00:57 |
| ybit | 15 members, $30/month | 00:58 |
| fenn | not renting seems only to be possible in rural areas, where you're lucky to get 15 members | 00:58 |
| ybit | drazak: what kind of side business does your current lab do? | 00:59 |
| ybit | fenn: so true | 00:59 |
| ybit | it would take time to get that kind of membership here, especially since it's so far from the city, most people wouldn't want to drive 20 minutes out of their way to the middle of nowhere it seems, but there are a few things you can do to keep them there: living quarters, food, beer, and..) | 01:01 |
| drazak | ybit: Dr. Lee has a company that sells reagents | 01:01 |
| ybit | drazak: link? | 01:01 |
| drazak | I'm trying to find it | 01:02 |
| drazak | I lost it | 01:02 |
| ybit | np | 01:02 |
| drazak | http://www.bmrservice.com/ | 01:03 |
| fenn | well since my other offers seem to be built on sand, if you need an expert scrounger i have ten years of experience | 01:04 |
| drazak | that's his store | 01:05 |
| ybit | tell him to get it working correctly under firefox or else | 01:06 |
| drazak | ybit: told him | 01:06 |
| drazak | like twice | 01:07 |
| ybit | eat some lucky charms and tell him a third time :P | 01:07 |
| drazak | rofl | 01:07 |
| drazak | ah | 01:07 |
| drazak | his wife is learning how to do it | 01:07 |
| drazak | and she's nice | 01:07 |
| drazak | so I don't want to insult her | 01:07 |
| ybit | anyway, now i've got $1000 and i'm considering making a miller, stm, book scanner or going ahead and purchasing some of the parts needed for daewoo's conversion | 01:12 |
| ybit | someone needs to nudge me in some direction right about now :) | 01:13 |
| ybit | it's 1am, my mind highly malleable | 01:14 |
| fenn | mill | 01:14 |
| ybit | that's what i'm thinking as well | 01:15 |

| bkero | THink I just ruined my rear bike wheel | 02:44 |
| fenn | next time take the lock off first | 02:45 |
| fenn | bkero: have you put much thought into a road worthy electric motorcycle? not just a motorized bicycle | 02:47 |
| fenn | just been drooling @ http://www.motoczysz.com/main.php?area=home | 02:48 |
| bkero | fenn: Yea, I've seen a lot | 02:49 |
| bkero | Made one | 02:49 |
| bkero | 3 lead-acid batteries, no controller | 02:49 |
| bkero | Just a badass throttle weird setup | 02:49 |
| fenn | the same guy built a completely new IC racing engine design and entire motorcycle from scratch | 02:49 |
| bkero | The throttle had 3 clicks. 1 click = 1 battery, 2 clicks = 2 batteries, 3 clicks = 3 batteries | 02:49 |
| bkero | I sat on the killacycle before it...died. | 02:49 |
| fenn | did the guy kill himself again? | 02:50 |
| bkero | No idea | 02:50 |
| fenn | well i'm not so into drag racing | 02:50 |
| fenn | turbonique pretty much stomped all over that in the 70's | 02:50 |
| fenn | showing that once again nobody actually cares about performance | 02:51 |
| bkero | Looks like I'm in the market for a new bike, again. | 02:52 |
| fenn | so pretty much DC motors is it? | 02:52 |
| bkero | Unless I can find a 700c wheel for free | 02:52 |
| fenn | you can undoubtedly find a wheel for ree | 02:53 |
| fenn | there is a local bike project, you just have to find it | 02:53 |
| bkero | Yea, most of those have 24" mountain bike wheels though | 02:53 |
| fenn | and you don't need a new bike just for a wheel? | 02:53 |
| fenn | you ought to be able to swap 27" rims if it matters | 02:54 |
| bkero | New wheel is the same price as another used bike. | 02:55 |
| fenn | it's surprising how small a 1000lb thrust peroxide rocket motor and assorted tanking is | 02:56 |
| fenn | where's my jetpack :( http://turbonique.tripod.com/index02.html | 03:00 |
| bkero | Jetpacks are hard. | 03:00 |
| fenn | yeah well what about all those other crazy things | 03:00 |
| fenn | which are Not For Sale | 03:01 |
| fenn | basically "what can you do with unlimited portable power" | 03:01 |
| fenn | for a short period of time | 03:02 |
| bkero | Anything I want | 03:02 |
| bkero | Superconductor | 03:02 |
| fenn | i'm thinking hydraulic exoskeleton with a high performance peroxide fueled backup pump | 03:03 |
| fenn | damn EESTOR | 03:04 |
| -!- Utopiah_ is now known as Utopiah | 03:04 | |
| * bkero is making a kotatsu tonight | 03:07 | |
| fenn | where do you do all this making? | 03:07 |
| bkero | Well, it's a kotatsu | 03:07 |
| bkero | So at home | 03:07 |
| fenn | er.. nm. i thought you said kodachi | 03:08 |
| bkero | No sir | 03:09 |
| bkero | kotatsu is a nice home item | 03:09 |
| katsmeow-afk | bkero: recycling center / scrap yard , i get all the bike tires i want just just for removing the rubber tires from them and returning the "clean" frames | 03:14 |
| katsmeow-afk | i end up returning most of the rims too, since all i was after was the crank and rear sprockets | 03:14 |
| katsmeow-afk | for your purposes, the tires are often rotted after a year, but then they are $10 at Walmart | 03:15 |
| katsmeow-afk | so i have a 3ft pile of rims to go back to the recycler out there now | 03:16 |
| katsmeow-afk | so i get sprockets and whatever chain and control cables, reflectors, etc i want, and he doesn't haveto go cut the rubber tires off | 03:18 |
| bkero | I have plenty of tires | 03:18 |
| katsmeow-afk | how do you ruin the rims? | 03:20 |
| bkero | This one had sealed bearings | 03:21 |
| bkero | and a broken spoke | 03:21 |
| katsmeow-afk | so replace the bearings and do without one spoke? | 03:21 |
| bkero | Can't replace the bearings, I broke the seal | 03:22 |
| bkero | They were press-fit in | 03:22 |
| katsmeow-afk | yeas, you pound them out with a rod from the otehr side | 03:22 |
| katsmeow-afk | same way you change front wheel bearings in a vehicle | 03:23 |
| katsmeow-afk | (rear wheel drive only) | 03:23 |
| bkero | I've done that before | 03:23 |
| katsmeow-afk | k | 03:24 |
| bkero | Press-fit bearings, needed about 2000lb/ft of force to press the outer shell in | 03:24 |
| bkero | Never replace front wheel bearings in a toyota | 03:24 |
| katsmeow-afk | hence pressing them back out or using a sturdy table and a small sledge | 03:24 |
| bkero | I've got a bench vice | 03:25 |
| bkero | and a pitman puller that I've tried using before | 03:25 |
| katsmeow-afk | vice may make it more difficult, you don't wanna clamp the outside of where you you are trying to press a bearing outof | 03:25 |
| bkero | I vice the spindle | 03:26 |
| bkero | http://media.photobucket.com/image/mr2%20front%20spindle/brust_2008/Camry/Front%20Wheel%20Brg/12SpindleOut2sm.jpg | 03:26 |
| katsmeow-afk | errrr,, if you still have the spindle in place, you aren't pressing the bearing out using any method i have ever used | 03:26 |
| fenn | what kind of bike has cartridge wheel bearings but costs less to replace than a wheel? | 03:27 |
| katsmeow-afk | ok, that url lists a front wheel drive car hub, what's that to do with a bike tire? | 03:28 |
| bkero | You were referencing wheel bearings in vehicles | 03:29 |
| katsmeow-afk | [03:24] <katsmeow-afk> (rear wheel drive only) | 03:29 |
| bkero | Yea, but the front wheels are mostly the same | 03:30 |
| fenn | i'm surprised i never realied it earlier but after reading altrusts.org i guess i'm an altruist | 03:30 |
| bkero | I couldn't find a picture | 03:30 |
| katsmeow-afk | http://autorepair.about.com/cs/generalinfo/l/bl219lib.htm | 03:31 |
| katsmeow-afk | to pop the outer races out of the thing they call the "disc", you run a rod thru the "disc" and press/hammer the race out | 03:32 |
| bkero | Yea, I've done that replacing the wheel bearings on a Grand Prix GTP before | 03:32 |
| katsmeow-afk | i've never seen or heard of anyone trying to pull those races out | 03:32 |
| katsmeow-afk | i know there are internal race pullers tho | 03:32 |
| bkero | http://i84.photobucket.com/albums/k15/toolmanholden/WheelBearingParts2.jpg | 03:33 |
| katsmeow-afk | seen and heard of them used on flywheels and tranny tails, but not wheel bearings | 03:33 |
| katsmeow-afk | so why aren't we seeing your wheel and their bearings which you cannot replace? | 03:34 |
| bkero | Never pulled apart my tranny, but I've swapped my clutch twice | 03:34 |
| bkero | Throw-out bearing is an easily-fit affair | 03:34 |
| bkero | They're ball bearings inside the wheel, and I can't get them to fit back in place | 03:34 |
| katsmeow-afk | but you said they were bad, replace them | 03:35 |
| katsmeow-afk | $5 per bearing? | 03:35 |
| bkero | The bearings? THe shell is actually built into the wheel | 03:35 |
| katsmeow-afk | shell? | 03:35 |
| katsmeow-afk | do you have sealed ballbearings or regular bike wheel bearings? | 03:36 |
| bkero | In the wheel assembly, there's a shaft that runs through the middle that connects to the bike frame | 03:36 |
| bkero | AroundOn the insideOn each side of the inside of the wheel, there are two rows of ball bearings in a cavity | 03:36 |
| bkero | The cavity is built into the wheel | 03:36 |
| bkero | Oh wait, I have my snazzy DSLR, I can show you with a picture. | 03:37 |
| bkero | Uploading | 03:43 |
| bkero | The bearings have no inner races | 03:43 |
| bkero | It's just shaft->bearings | 03:44 |
| bkero | http://staff.osuosl.org/~bkero/bicycle/ | 03:47 |
| katsmeow-afk | holycrap, 7mpixels | 03:47 |
| katsmeow-afk | er, mbytes | 03:48 |
| bkero | 10mp camera | 03:48 |
| katsmeow-afk | yeas,, mogrify | 03:48 |
| bkero | It's a little old, but yea | 03:48 |
| bkero | Too big for your connections? | 03:48 |
| katsmeow-afk | no, it's ok | 03:48 |
| katsmeow-afk | i'd have zoomed the camera in to the area of interest tho | 03:49 |
| bkero | I did | 03:49 |
| bkero | That was about 1-2 inches away | 03:50 |
| bkero | 14-42mm lens | 03:50 |
| bkero | I do find it weird that there's no inner shell | 03:50 |
| katsmeow-afk | you have none with the spindle out | 03:50 |
| katsmeow-afk | this looks like a typical bike | 03:52 |
| bkero | That's because it's a gigantic bitch | 03:52 |
| bkero | I spent about four hours getting it out to try to get the freewheel off | 03:52 |
| katsmeow-afk | http://staff.osuosl.org/~bkero/bicycle/pa030551.jpg shows 3 nuts on the spindle, when you take those off, the spindle won't fall out the other side? | 03:53 |
| bkero | I can't get the inner one off that side, gotta take it off the other | 03:54 |
| katsmeow-afk | back the middle one up against the outer one, tighten/jamb it there, put a wrench there and one on the inner nut, it shuld come right off | 03:55 |
| bkero | Tried that, both just spun off :/ | 03:56 |
| bkero | I'll try again | 03:56 |
| katsmeow-afk | nother trick is to take a old nut you'll never put ona bike again, slot it in the bandsaw, screw it on,and collapse it onto the shaft with heavy vicegrips | 03:56 |
| bkero | heh | 03:57 |
| katsmeow-afk | i wonder what shipping two of them to you would cost | 03:58 |
| katsmeow-afk | COD, of course, i'm dead broke in deep doo,, mean debt | 03:58 |
| bkero | heh | 03:59 |
| bkero | Dont worry abnpout that | 03:59 |
| katsmeow-afk | here's me scrapping them out for sprokets : http://designerthinking.com/bikesprockets.html | 03:59 |
| katsmeow-afk | doing it that way beats removing the carrier, which i didn't need anyhow | 04:01 |
| bkero | nice haul | 04:01 |
| * katsmeow-afk nods ,, lucky | 04:02 | |
| katsmeow-afk | i didn't get them all at once, and they are rusty because they sat outside during the Dog Era here | 04:02 |
| katsmeow-afk | i have the matching front wheels too | 04:03 |
| fenn | you can de-rust them with electrolysis | 04:03 |
| fenn | soak in washing soda solution and attach electrodes | 04:04 |
| katsmeow-afk | or use a wire brush in a "body grinder" ? | 04:04 |
| fenn | after the experience of having a functional machine tool i start to question whether it makes sense to scavenge stuff like sprockets if you could expend a similar amount of effort to make a jig for making an unlimited supply of them | 04:05 |
| bkero | I can't figure out how to do the 2-nut trick | 04:05 |
| bkero | They both just spin :/ | 04:05 |
| katsmeow-afk | i tend to agree, but these are hardened, free, available, etc | 04:05 |
| fenn | you need special wrenches for the cones | 04:05 |
| katsmeow-afk | fenn, he cannot lock the threaded rod down | 04:06 |
| katsmeow-afk | standard wrenches willwork, they overlap a bit | 04:06 |
| fenn | you loosen one nut against the other with two wrenches on the same side of the wheel | 04:06 |
| katsmeow-afk | most likely metric, naturally | 04:06 |
| fenn | regular wrench is too fat to fit in the flat | 04:06 |
| katsmeow-afk | yeas,it overlaps out | 04:07 |
| katsmeow-afk | but still grips, if you mind it | 04:07 |
| bkero | I can't fit a wrench around the inside nut | 04:07 |
| fenn | i guess you could grind down a regular wrench | 04:07 |
| bkero | Not going to ruin wrench | 04:07 |
| fenn | or grind a piece of thick sheet metal | 04:07 |
| fenn | to proper internal diameter | 04:07 |
| katsmeow-afk | can't fit the wrench to the nut?? | 04:07 |
| fenn | or whatever the distance between two lines is called | 04:07 |
| katsmeow-afk | gap | 04:07 |
| fenn | dimension? | 04:08 |
| bkero | The inside nut | 04:08 |
| fenn | it's 15mm | 04:08 |
| katsmeow-afk | bkero, what is stopping you? | 04:08 |
| bkero | katsmeow-afk: My wrenches are too fat | 04:08 |
| fenn | http://images.google.com/images?hl=en&q=cone+wrench&um=1&ie=UTF-8&sa=N&tab=wi | 04:08 |
| katsmeow-afk | did you screw both the other nut out to the end of the rod? | 04:08 |
| bkero | Yea | 04:09 |
| katsmeow-afk | or, can you lock the nuts on the other side of the wheel and use them? | 04:09 |
| bkero | Heh | 04:09 |
| bkero | The other side with the freewheel is recessed | 04:09 |
| bkero | and I jammed a screwdriver, some needlenose pliers, watever I could to make the other nut stay in place | 04:09 |
| katsmeow-afk | but the threaded rod isn't, bind the two nuts over there | 04:09 |
| fenn | you arent supposed to loosen the recessed side | 04:09 |
| katsmeow-afk | fenn, re rust, i need a cheaper version of this : http://www.rustguy.com/www.rustguy.com/index.html | 04:10 |
| bkero | Maybe I'm not binding the nuts correctly | 04:10 |
| bkero | I've got two nuts on the side without the freewheel(two extra) | 04:10 |
| bkero | Both are spinning | 04:11 |
| fenn | are you sure they're spinning wrt the axle and not the axle itself spinning? | 04:11 |
| bkero | The axle itself is spinning | 04:11 |
| bkero | Trying to figure out how to have it not do that | 04:11 |
| fenn | the two nuts are locked to each other, so to loosen them you have to apply torque to both nuts | 04:12 |
| fenn | this typically involves two wrenches | 04:12 |
| bkero | I have two wrenches here | 04:12 |
| fenn | but one of them is too fat right? | 04:13 |
| bkero | I'm not worrying about that one | 04:13 |
| bkero | There's a nut against that one I have to remove first | 04:13 |
| fenn | to loosen the inner nut you need to make or acquire a thinner 15mm wrench | 04:13 |
| fenn | screwdriver isn't going to do it | 04:13 |
| fenn | needle nose pliers won't work either | 04:13 |
| bkero | If I can get the nut against the inner nut out | 04:14 |
| bkero | I can just use a regular 15mm wrench | 04:14 |
| katsmeow-afk | take both nuts off that side, put them on the otehr side, then you'll have clearance | 04:14 |
| fenn | sigh | 04:14 |
| katsmeow-afk | oohh, | 04:14 |
| katsmeow-afk | that's the problem, ok | 04:14 |
| katsmeow-afk | i thought we were further along, oops | 04:14 |
| bkero | I added two nuts(that aren't pictured) | 04:14 |
| bkero | to use to bind | 04:14 |

| katsmeow-afk | bind on the opposite side of the wheel, then you shold be able to take all the nuts off where you're working | 04:15 |
| * bkero tries that | 04:15 | |
| bkero | When binding | 04:15 |
| bkero | I want to screw two nuts against each other | 04:15 |
| katsmeow-afk | yeas | 04:16 |
| bkero | THen which one do I want to hold in place? THe inner one, our outer one? | 04:16 |
| katsmeow-afk | either | 04:16 |
| katsmeow-afk | or | 04:16 |
| katsmeow-afk | the one which, when forced against, binds more | 04:16 |
| bkero | I think the axle is going to spin, but I"ll try it | 04:16 |
| bkero | The axle spins, and both are loosened, at least all the other times I've tried | 04:16 |
| * katsmeow-afk gives up then | 04:17 | |
| fenn | [1][2]---[3][4>-------<5][6]---- | 04:18 |
| fenn | put wrench on 1 and 3 | 04:18 |
| fenn | if you're lucky, 4 won't move | 04:18 |
| katsmeow-afk | nice ascii art :-) | 04:18 |
| bkero | Where is the internal axle in that? | 04:19 |
| fenn | axle is ---- | 04:19 |
| bkero | Ah, between the < and > | 04:19 |
| bkero | Ok, I'll try with the binding ones on the same side as the one I'm trying to remove | 04:20 |
| bkero | When I grab 1 and 3, and wrench, 1 and 2 just spin up the threads towards 3 | 04:22 |
| fenn | because 3 and 4 are locked tighter | 04:23 |
| katsmeow-afk | so are 5-6 , bear against them? | 04:23 |
| fenn | can't get a wrench on them | 04:23 |
| katsmeow-afk | oh, recessed | 04:23 |
| fenn | btw why are you removing the bearings? | 04:24 |
| katsmeow-afk | got a spare nut you can slot for the 1-2 pair? | 04:24 |
| bkero | Bearings are shot | 04:24 |
| bkero | and I was trying to remove the center rod so I could get the freewheel off | 04:24 |
| bkero | You're suggesting 3 nuts for binding? | 04:25 |
| katsmeow-afk | no | 04:25 |
| katsmeow-afk | the sloted nut visegrip approach | 04:25 |
| bkero | Not sure if I'm familiar | 04:25 |
| katsmeow-afk | i mentioned it 10 minutes ago | 04:25 |
| fenn | katsmeow-afk: to prevent the vise grips from damaging the threads right? | 04:25 |
| katsmeow-afk | and make more grip area on the shaft | 04:26 |
| katsmeow-afk | and make use of the wedging action of the threads collapsing on each other | 04:26 |
| fenn | i would worry about crushing a hollow axle | 04:26 |
| katsmeow-afk | the spindle is solid | 04:26 |
| katsmeow-afk | look at it | 04:27 |
| bkero | axle isn't hollow | 04:27 |
| fenn | i dare not look at a 7MB photo on this poor creature | 04:27 |
| katsmeow-afk | it's ~3/8 dia hardened solid | 04:27 |
| fenn | it's all i can do to keep the screen from falling off | 04:27 |
| fenn | did i mention i'm accepting laptop donations? | 04:27 |
| fenn | especially small ones that aren't broken | 04:28 |
| katsmeow-afk | no desktop donation? | 04:28 |
| fenn | well, all i really need for my computer-in-a-tub is an lcd monitor | 04:29 |
| * katsmeow-afk notes if you are lucky, you can pick up 2005 era puters for $30 | 04:29 | |
| fenn | this computer was $65 brand new | 04:29 |
| fenn | i had to buy ram and heastink separate | 04:30 |
| * katsmeow-afk nods | 04:30 | |
| fenn | cheaper to get a new mobo than try to find DDR1 RAM | 04:30 |
| katsmeow-afk | really? i just got 10gigs of ddr for $50 | 04:31 |
| fenn | i should just finish this dumb wearable project already before my laptop dies | 04:31 |
| katsmeow-afk | 10 gigs of any ram for $50 is a bargain, assuming one can use it | 04:32 |
| fenn | katsmeow-afk: what size individual sticks? | 04:32 |
| katsmeow-afk | most are 256mb , a couple 512's | 04:32 |
| fenn | see that's no good | 04:32 |
| katsmeow-afk | why? | 04:32 |
| fenn | because most mobo's only have 2 slots | 04:32 |
| katsmeow-afk | oh,, most of mine have 4 | 04:33 |
| katsmeow-afk | but i figured i'd end up using most of these in avr stuff, like as 32megx8 chips, or other projects | 04:34 |
| katsmeow-afk | beats buying $5 flash for them all, this is 300+ individual chips | 04:34 |
| fenn | i thought computer memory required some kind of controller chip to refresh periodically | 04:34 |
| katsmeow-afk | sure, a counter | 04:35 |
| bkero | Still having issues with this damn thing, argh | 04:35 |
| fenn | how often does it need refreshing? and do you have to feed back the correct value to the chip? | 04:35 |
| katsmeow-afk | need one for sequential read or write independant of the avr anyhow | 04:35 |
| fenn | ah see you're already way beyond my level of jumping-in-ness | 04:36 |
| katsmeow-afk | no, tho you could make a smart system using the avr int and pwm outputs | 04:36 |
| fenn | so the counter is just so it doesn't draw a lot of current refreshing everything at once? | 04:37 |
| katsmeow-afk | making it smart means one of 2 things: you're eating up cpu clocks in your system, or you're throwing a separate atTiny chip at the problem | 04:37 |
| fenn | bkero: i suggest setting it aside for tonight and taking it to the bike project, where they undoubtedly have more cone wrenches than you will know what to do with | 04:37 |
| bkero | fenn: Yea, but that's tomorrow | 04:38 |
| katsmeow-afk | you can't refersh it all at once, you refres a collum or row at a time | 04:38 |
| bkero | and to get there I'll have to use my bike :P | 04:38 |
| fenn | ah but it's today | 04:38 |
| fenn | you have all day to walk there :P | 04:38 |
| bkero | and I'm still not sure that the bearings in this are repairable | 04:38 |
| bkero | or replacable in this wheel | 04:38 |
| fenn | actually i bet you can still ride it somewhat | 04:38 |
| katsmeow-afk | maybe not repairable, you can get new balls, butnot new races | 04:38 |
| katsmeow-afk | the inner race on the shaft is hardened, but i don't believe the outer race is | 04:39 |
| fenn | they are hardened different amounts | 04:39 |
| fenn | i think the outer race is harder since it's not replaceable | 04:39 |
| katsmeow-afk | maybe i am thinking of crank bearings, where the outer race is a stamped sheet common steel | 04:40 |
| fenn | yeah those are groady | 04:40 |
| fenn | single piece cranks | 04:40 |
| fenn | blech | 04:40 |
| bkero | The bearing cone on mine is actually threaded | 04:42 |
| katsmeow-afk | yeas, to adjust play | 04:43 |
| bkero | How much play do I want? | 04:43 |
| * bkero pulls out the micrometer | 04:43 | |
| katsmeow-afk | barely feelable | 04:43 |
| bkero | I have about 1/4 inch right now | 04:44 |
| katsmeow-afk | or, tighten the cone till you feel resistance to turning the shaft by hand, then back out 1/4 turn till there's no resistance | 04:44 |
| katsmeow-afk | 1/4 inch play? sheesh! | 04:44 |
| bkero | !! | 04:48 |
| bkero | Got it | 04:48 |
| fenn | you want a slightly negative amount of play (preload) | 04:49 |
| fenn | so when the bearing is under strain it doesn't pull apart, instead there is elastic force holding it together | 04:49 |
| katsmeow-afk | in heavy use, the slight negative preload allows to heat buildup expansion and grease to flow | 04:50 |
| fenn | hence "slight" | 04:50 |
| fenn | better than it bouncing around inducing shock loads at least | 04:50 |
| fenn | no such thing as perfect after all | 04:50 |
| katsmeow-afk | if you tighten a car front bearings, and drive the interstate for 20 min, you'll find the wheel trying to sieze | 04:51 |
| katsmeow-afk | yeas, you want minimum momentum to build | 04:51 |
| fenn | i've never seen a car with adjustable bearings | 04:51 |
| katsmeow-afk | however, if you go for 100% metal-metal contact, youlose most of the benefit of lube | 04:52 |
| katsmeow-afk | fenn, they use tapered roller bearings, which are adjustable by the nut that holds the wheel on the spindle | 04:52 |
| bkero | pictures | 04:53 |
| fenn | so the 'adjustment' is the torque? i mean it's not a jamb nut like on a bicycle | 04:53 |
| katsmeow-afk | [03:32] <katsmeow-afk> http://autorepair.about.com/cs/generalinfo/l/bl219lib.htm | 04:54 |
| * bkero uploads pictures | 04:54 | |
| katsmeow-afk | the washer they show is keyed to not turn, the nut is castellated, the cotter holds it in place | 04:55 |
| bkero | http://staff.osuosl.org/~bkero/bicycle/pa030557.jpg onward | 04:56 |
| katsmeow-afk | to adjust, turn the wheel by hand as you tighten the nut, when overtight the wheel will slow, so back off till it spens freely, repeat more slowly, back off till you have free spin and *barely* feel slop | 04:57 |
| katsmeow-afk | or,, if you have bad feelings, back off till it spins freely | 04:57 |
| katsmeow-afk | You don't have permission to access /~bkero/bicycle/pa030557.jpg on this server | 04:57 |
| bkero | Try now | 04:58 |
| katsmeow-afk | www.goes.noaa.gov went down | 04:58 |
| katsmeow-afk | you got it out :-) | 05:00 |
| bkero | I did | 05:00 |
| bkero | The recessed side wasn't that tight | 05:00 |
| katsmeow-afk | <orchestral sounds> out work is done | 05:00 |
| bkero | I'm not sure what to do now though | 05:00 |
| bkero | Besides try to stick the bearing that fell out back in the right place | 05:01 |
| bkero | It's hard because they're recessed | 05:01 |
| bkero | If I could get the freewheel off, maybe | 05:01 |
| bkero | But I don't have a freewheel puller tool, any clue how to do that without one? | 05:01 |
| fenn | you should loosen the other side so you can get it apart while partially assembled | 05:01 |
| katsmeow-afk | well, the shaft doesn't care which way it's in | 05:01 |
| fenn | the offset does matter though, so remember where the nuts were positioned | 05:01 |
| katsmeow-afk | why pull the freewheel if thepoint was to fix the bearings? | 05:02 |
| bkero | fenn: Look at the cone nut, I can't fit a 15mm around it because it's rounded | 05:02 |
| bkero | Because my freewheel skips | 05:02 |
| bkero | Replaced the chain | 05:02 |
| bkero | and I have a new freewheel sitting next tome | 05:02 |
| katsmeow-afk | it's not rounded, there's 2 flats | 05:02 |
| katsmeow-afk | oh, the thin enough wrenc problem | 05:02 |
| bkero | Yes | 05:02 |
| katsmeow-afk | slot nuts, place on shaft, clamp/collapse in vise, turn off the regular nut | 05:03 |
| bkero | No vice handy | 05:03 |
| katsmeow-afk | you said you have a bench vise | 05:04 |
| bkero | Just moved apartments, I don't have a bench to screw it against | 05:04 |
| katsmeow-afk | it's 5am, i need to do stuff irl | 05:04 |
| katsmeow-afk | noaa was down due to dns errors, it's back up | 05:05 |
| bkero | You run noaa? | 05:05 |
| katsmeow-afk | if itmatters | 05:05 |
| katsmeow-afk | no | 05:05 |
| katsmeow-afk | i peroidically log snapshots of earth, so ic an , for instance, play Katrina forwards and backwards whenever i want | 05:07 |
| bkero | Nice | 05:07 |
| katsmeow-afk | see what goes on seasonally, year to year, see that yesterday i did not want to be off the south west coast of New Zealand | 05:08 |
| katsmeow-afk | they had 50ft+ waves | 05:08 |
| katsmeow-afk | a rare off-the-scale large area | 05:08 |
| bkero | Nice waves | 05:08 |
| fenn | that was due to an earthquake (or series of quakes) | 05:10 |
| katsmeow-afk | err, the south west tip of NZ ? | 05:10 |
| fenn | i could be wrong.. this is the info i'm referencing http://aardvark.co.nz/daily/2009/1001.shtml | 05:11 |
| katsmeow-afk | i am showing the event off NZ was a larger area of severe waves off Tasmania 10/1 7:14am, and by 10/2 2:15 pm it had drifted easterly and up and abated against NZ | 05:15 |
| katsmeow-afk | the waves were back on-scale by 10/3 4:15am | 05:16 |
| katsmeow-afk | currently the waves are still high, over a larger area of southwest NZ coast than 2 days ago | 05:16 |
| katsmeow-afk | not as high as 2 days ago | 05:17 |
| katsmeow-afk | the waves are worse than the two typhoons in the northweat pacific atm | 05:17 |
| katsmeow-afk | http://designerthinking.com/temp/2009-10-03-05-14%20-%20waves.gif | 05:19 |
| katsmeow-afk | it WAS http://designerthinking.com/temp/2009-10-02-13-14%20-%20waves.gif | 05:20 |
| katsmeow-afk | water temp at the time was 50F, surfing wasn't adviseable | 05:21 |
| katsmeow-afk | and the waves were washing strongly onshore | 05:22 |
| katsmeow-afk | ok, things to do, bbl | 05:25 |
| bkero | Bike's pieced back together | 05:54 |
| fenn | katsmeow-afk: do you have an animated version of that wave map? | 05:57 |
| bkero | O_o Apparently my bike will go for $250 on ebay if it's in good condition. | 05:58 |
| bkero | Nice for finding it in a dumpster | 05:58 |
| katsmeow-afk | fenn , nope, i have a script to play individual pics | 06:46 |
| katsmeow-afk | noaa updates it only irratically every 6-8 hrs | 06:46 |
| katsmeow-afk | the wave and temperature data is a commercial site that's updated more often, still no movie | 06:47 |
| bkero | Rear wheel's pretty loose | 06:50 |
| bkero | The bearings feel like shit, I can't pack them in evenly | 06:50 |
| bkero | Take it to a bike coop tomorrow, see if there's anyone around with the tools and know-how to see if it's fixable | 06:50 |
| katsmeow-afk | they should fall in and be even by themselves | 06:51 |
| bkero | Except the ones at the top, which just fall down | 06:52 |
| bkero | and when laid flat I can't prod them into place | 06:53 |
| fenn | are those loose balls or is there a cage? | 06:53 |
| katsmeow-afk | prolly loose, to allow more in there | 06:53 |
| katsmeow-afk | but if loose, there shold be enough to fill the space tweenthe races | 06:54 |
| fenn | well anyway you usually need some grease to get them to stick | 06:54 |
| katsmeow-afk | ds | 06:54 |
| katsmeow-afk | er | 06:54 |
| * katsmeow-afk nods | 06:55 | |
| bkero | I didn't really see a cage | 06:56 |
| katsmeow-afk | are there enough balls? | 06:56 |
| bkero | I couldn't really see a descernable pattern | 06:56 |
| bkero | Yes, I haven't lost any of the balls | 06:56 |
| bkero | I just can't find an even pattern to put them in | 06:56 |
| katsmeow-afk | pattern? | 06:56 |
| bkero | even distribution | 06:57 |
| katsmeow-afk | if there is space, you are missing balls | 06:57 |
| bkero | I'm not missing any, very clean, open workspace | 06:57 |
| katsmeow-afk | there shold be enough balls that they are pretty much touching each otehr all the way round | 06:57 |
| bkero | Yes, but they're not sitting next to each other | 06:57 |
| bkero | They're staggered | 06:58 |
| katsmeow-afk | i didn't say YOU lost any, but you did get it from a dumpster | 06:58 |
| katsmeow-afk | they won't stay staggered | 06:58 |
| bkero | There are little spikes that stick up between the half-rows | 06:58 |
| katsmeow-afk | pics | 06:58 |
| bkero | Tried to take some | 06:58 |
| -!- wrldpc2 [n=benny@ool-ad03fe34.dyn.optonline.net] has quit [Read error: 60 (Operation timed out)] | 07:00 | |
| bkero | Camera wouldn't autofocus in there, I didn't try to manually focus it. Flash was a real pain up close too, that's the big black spot on the bottom. I'll take some pics tomorrow if I tear it down again | 07:00 |
| bkero | This wheel makes me very angry. | 07:01 |
| katsmeow-afk | me too, i could go outside and get my paws greasy and take a pic of what i am trying to find online | 07:13 |
| katsmeow-afk | dafgwdwed Timken lists "cageless" on every dwrged one of their dfamner webpages | 07:15 |
| fenn | looking for this? http://www.processandpackaging.com/images/products/thumbs/P5258.jpg | 07:16 |
| bkero | So cold outside my bed. | 07:16 |
| katsmeow-afk | fenn, that obviously has a cage | 07:17 |
| fenn | of course | 07:17 |
| katsmeow-afk | i did say "cageless" | 07:17 |
| fenn | can you actually fit more rollers in without a cage? | 07:18 |
| katsmeow-afk | yeas, often double the rollers/balls, and doubling the load capacity | 07:18 |
| katsmeow-afk | http://www.timken.com/en-us/products/bearings/productlist/roller/thrust/TaperedRollerThrust/Pages/Oscillating.aspx | 07:18 |
| katsmeow-afk | speed rating may drop some tho, it won't be 20,000 rpm | 07:19 |
| fenn | you won't get 20,000rpm from a tapered roller bearing anyway | 07:20 |
| * katsmeow-afk nods | 07:20 | |
| fenn | so i still don't see the advantage | 07:21 |
| katsmeow-afk | http://www.smallparts.com.au/images/product_information/D608_FC_120.jpg | 07:21 |
| katsmeow-afk | http://www.smallparts.com.au/images/product_information/cage_fc_108.jpg | 07:21 |
| fenn | why can't you just have zero plus epsilon spacing between the caged rollers? | 07:22 |
| katsmeow-afk | compare to http://www.smallparts.com.au/images/product_information/bearing_316_108.jpg | 07:22 |
| katsmeow-afk | the number of contact points, therefor the radial load capacity, is doubled in the full complement type | 07:22 |
| fenn | well that's just ridiculous | 07:22 |
| katsmeow-afk | if the cage itself gets too small, it shatters, or wears thru | 07:22 |
| katsmeow-afk | usually, small cages shatter and wreck the bearing | 07:23 |
| fenn | the bulk of the cage is on the sides though | 07:23 |
| fenn | in the two triangular volumes above and below the contact point | 07:23 |
| katsmeow-afk | it's symetric, it's identical stamping or pour | 07:23 |
| fenn | stamped is obviously not the most compact cage design | 07:24 |
| katsmeow-afk | <shrug> either way, i have seen lotsa cracked cages, and bearings pulled due to bits of cage coming loose inside the bearing | 07:24 |
| katsmeow-afk | poured brass is most compact, and highest prices | 07:24 |
| fenn | do they make silicone cages? or did i make that up? | 07:24 |
| katsmeow-afk | you made that up | 07:25 |
| katsmeow-afk | google it | 07:25 |
| fenn | well it seems like a good idea to me :) | 07:25 |
| katsmeow-afk | you can pour in your own lube, of course | 07:25 |
| fenn | pop the balls in, elasticity keeps them in | 07:25 |
| fenn | or urethane | 07:26 |
| katsmeow-afk | well, yeas and no, full complements are made diferently | 07:26 |
| katsmeow-afk | see on http://www.smallparts.com.au/images/product_information/cage_fc_108.jpg , the 5 oclock positon on the outer race, there's a divot | 07:26 |
| katsmeow-afk | there isn't one on any caged race bearings | 07:27 |
| katsmeow-afk | oh,, you mean a rubber cage | 07:27 |
| katsmeow-afk | heh, no | 07:27 |
| katsmeow-afk | so bkero, you see how many balls, and their spacing, yu should have in your axle? : http://www.smallparts.com.au/images/product_information/cage_fc_108.jpg | 07:29 |
| katsmeow-afk | nearly touching, all the way round | 07:29 |
| katsmeow-afk | and i didn't haveto get my paws greasy :-) | 07:29 |
| katsmeow-afk | at most, you'd have a grand total of 1/2 ball dia space if you push all the balls together | 07:31 |
| katsmeow-afk | if you have more space, you are missing some | 07:31 |
| * katsmeow-afk hopes bkero hasn't left for the bike shop to sugegst they check his,, well, <cough> | 07:33 | |
| fenn | apparently there is something called a spherical tapered roller bearing, looks to be something halfway between a ball and a roller http://www.timken.com/EN-US/products/bearings/productlist/roller/thrust/PublishingImages/Spherical-Roller-TSR_150.jpg | 07:33 |
| katsmeow-afk | yeas | 07:33 |
| katsmeow-afk | slightly diff specs compared to tapered or flat roller | 07:34 |
| katsmeow-afk | i have sets of matching (but used) double tapered roller bearings, 8 inches OD, i cast a concrete slab in the cellar 15 yrs ago to put a large lathe on, then found rottwilers in my cellar and never did any more work there | 07:37 |
| katsmeow-afk | got tube for the bearings, got 2 inch thick plate cut to house them and make the lathe head | 07:37 |
| katsmeow-afk | all wasted time, money, effort | 07:37 |
| fenn | presumably it's still there? | 07:38 |
| katsmeow-afk | yeas | 07:38 |
| katsmeow-afk | well, i brought the bearings upstairs | 07:38 |
| katsmeow-afk | one of the 8 inch channel pieces i used to make a overheadlift in the driveway | 07:39 |
| katsmeow-afk | http://designerthinking.com/images/robotics/bike%20tire%20collection.jpg | 07:40 |
| katsmeow-afk | http://designerthinking.com/images/robotics/bearing%20collection.jpg | 07:41 |
| katsmeow-afk | i have 2 more large bearings than those, and 4 in the 2 pillow blocks out by the rusted up Bridgeport | 07:43 |
| katsmeow-afk | the ones outside are at least 6 inch ID | 07:43 |
| -!- wrldpc2 [n=benny@64.20.169.162] has joined #hplusroadmap | 07:43 | |
| katsmeow-afk | those are all the *used* bearings, i have a stash of new ones as well, prolly 100's of 608z type | 07:44 |
| katsmeow-afk | got them for pennies, skateboard type,, with the wheels, naturally | 07:44 |
| fenn | heh | 07:45 |
| fenn | don't try to use used skateboard bearings | 07:45 |

| katsmeow-afk | Texas is now putting out the call to scientists: Come and get the money. | 16:52 |
| katsmeow-afk | Texas is ready to try by investing $3 billion over the next decade in cancer research and prevention, which would make the state the gatekeeper of the second largest pot of cancer research dollars in the country, behind only the National Cancer Institute. | 16:52 |
| drazak | NCI is lulzy | 16:55 |
| drazak | we might get money from them though | 16:56 |
| drazak | we immortalized some stem cells in a way that means they're implantable without cancer | 16:56 |
| drazak | patent pending (seriously) | 16:56 |
| katsmeow-afk | what's "preserved" haveto do with "without cancer" ? | 16:57 |
| drazak | immortalized cells when implanted have a tendency to cause cancer | 16:58 |
| drazak | they have no natural kill method | 16:58 |
| drazak | a lot of immortalized cell lines are from cancers | 16:58 |
| katsmeow-afk | oh | 16:58 |
| katsmeow-afk | sounds wierd | 16:58 |
| drazak | well, more like they become cancer, not cause it | 16:58 |
| katsmeow-afk | i woldn't think that "no kill" = "multiply lots too" | 16:59 |
| drazak | oh yeah | 17:00 |
| drazak | they multiply faster than normal cells | 17:00 |
| katsmeow-afk | i assume you are wrapping up telomeres, or keeping them from falling off? how can that cause uncontroleld reproducton, since native stem cells don't? | 17:00 |
| drazak | there's different method | 17:00 |
| drazak | the problem with native stem cells is that after 6 or 7 passages they get bigger and rounder, and eventually stop multiplying | 17:00 |
| katsmeow-afk | k, patented, gotcha | 17:01 |
| katsmeow-afk | issat from errors in uncoiling and recoiling? | 17:01 |
| drazak | there's different genes you can turn on and off and whatnot | 17:01 |
| drazak | there's different theories, but mostly that, yeah | 17:01 |
| drazak | you'll read a paper and it'll say it's the coiling/uncoiling and another that says it's just the structure before coiling and all that | 17:02 |
| katsmeow-afk | beats them coiling upwrong first time and becoming a sorta mad cow variant, i spose | 17:02 |
| drazak | mad cow is something different | 17:02 |
| katsmeow-afk | i know | 17:02 |
| drazak | :) | 17:02 |
| katsmeow-afk | i was just thinking of the reverse coil | 17:03 |
| drazak | ah right | 17:03 |
| drazak | anyway brb cookies and bathroom | 17:03 |
| katsmeow-afk | that dam "explosion" in August wasn't a transformer fault : | 17:04 |
| katsmeow-afk | Rostekhnadzor director Nikolai Kutin outlined a report on the August accident at the Sayano-Shushenskaya dam and described its technical causes in chilling detail. | 17:04 |
| katsmeow-afk | He said Saturday that part of an overstressed turbine unit snapped off and sailed into the air, starting flooding, short circuits and wreckage that crippled the plant and doomed dozens of workers in seconds. | 17:04 |
| drazak | katsmeow-afk: btw the gene we're patenting is CDK-1 for immortalizing | 17:09 |
| drazak | the process is the important part | 17:09 |
| * katsmeow-afk nods while munching dinner | 17:10 | |
| katsmeow-afk | farking football preemted news again | 17:11 |
| drazak | we have some passage 12 hMSCs that we immortalized with cdk-1 | 17:11 |
| katsmeow-afk | have you been able to immortalise non-embryonic cells? | 17:13 |
| drazak | those are non-embryonic | 17:13 |
| drazak | only ES's are embryonic | 17:13 |
| drazak | these are from the mesenchyme or bonemarrow | 17:14 |
| katsmeow-afk | ah | 17:14 |

| katsmeow-afk | i been outside stretching the roof over the driveway, i are pooped | 17:15 |

| katsmeow-afk | i thoughtit might be a cable error, but the 2nd drive is testing fine ont he same cable | 17:16 |
| katsmeow-afk | someone suggested pulling the bios battery on the Dell 4600's to getthem to see new drives, that did the trick, Dell has hobbled the bios to not run auto or manual drive detections, removing the cell lets it go dead, and it works now | 17:18 |

| kanzure_ | no | 20:23 |
| kanzure_ | but i'm somehow now responsible for openstim | 20:24 |

| ybit | "Apparatus for fabrication of thin films Niklas Bondestam | 20:58 |
| genehacker | PLEASE REFER TO EXTRACTING USEFUL INFORMATION FROM PATENTS | 21:04 |
| ybit | genehacker: please search for netiquette :P | 21:13 |
| ybit | all caps is a no no | 21:13 |
| ybit | anyway, what are you referring to? | 21:13 |
| ybit | finally, had been looking for this paper for awhile: Development of meso-scale machine tool (mMT) systems | 21:27 |

| ybit | ^ the quote that started the search, search hasn't ended, still reading to see if this is that machine | 21:34 |
| ybit | yup | 21:35 |
| ybit | "The input to the MCU is a standard part program in G-code that can be either manually programmed or generated by post-processing the Cutter Location (CL) data file using a CAD/CAM system." | 21:36 |

| ybit | how much are we talking for a Physik Optex Pro ArF excimer laser? | 22:18 |
| ybit | I think physik was ovetaken by coherent, and the aren't releasing prices on their site | 22:18 |
| genehacker | huh | 22:23 |
| ybit | s/the/they | 22:25 |
| ybit | we were discussing prices of lithography, oh, so many months ago. it shouldn't cost thousands of dollars | 22:25 |
| ybit | you can get finer detail with stm litho for a few hundred | 22:26 |
| genehacker | but it's slow | 22:26 |
| ybit | yeah, but more precise, and it's not like this is for industrial use | 22:28 |
| genehacker | what do you want to lithograph? | 22:31 |
| ybit | build things | 22:43 |
| ybit | what do you want to do with milling machine, or a welder? use them :P | 22:43 |
| ybit | wish there were more details on the micro-milling machine above | 22:44 |
| genehacker | above where? | 22:46 |
| genehacker | what material would you like to lithograph? | 22:46 |
| ybit | was afk just now, and genehacker, you weren't connected when i posted links, i'll copy/paste in a PM for you | 22:49 |
| ybit | re: 22:46 < genehacker> what material would you like to lithograph? | 22:51 |
| ybit | i don't know yet | 22:51 |
| genehacker | thanks for the links | 22:56 |
| ybit | np | 22:56 |
| genehacker | interesting that they're doing milling with voice coils | 22:56 |
| ybit | sent an email to a few of those guys, hoping to hear back, since the details of their setup were sparse | 22:56 |
