00:00 furrywolf I remember some big lens, almost the width of the paper, in an old hp laserjet I took apart...
00:00 gaze__ nah. But... those are super useful.
00:01 furrywolf maybe it wasn't the laserjet, don't remember which printer I pulled it from, but it was a very nice lens, and I suspect its job was to do what you're doing...
00:01 gaze__ the entire polygonal mirror assembly inside most laser printers is very useful for structured light
00:01 gaze__ honestly I'd be doing that to make my stereolithography machine but I have a thing for galvos.
00:02 furrywolf make it powerful enough you can do SLS with it too. :)
00:03 gaze__ oh sure! the system I have is totally capable of SLS
00:03 gaze__ err... am building
00:03 gaze__ if I switch the optics out for IR and put a co2 laser on it
00:03 furrywolf of plastic, or powder metallurgy?
00:04 gaze__ the thing people miss about doing SLS in the hobby community is that it needs MUCH higher power than they think
00:04 gaze__ the reasoning is "my blue laser can melt plastic, so I can do SLS with it!"
00:04 furrywolf yes. melting metal is hard. at a random guess, I'd say 50W continous would be a starting point...
00:04 gaze__ well with plastic
00:04 furrywolf just pulling a number out of my ass.
00:04 gaze__ I mean SLS with plastic needs VERY high power
00:05 gaze__ the problem is you need to deliver a ton of energy very quickly
00:05 gaze__ if you don't do it fast enough, it'll diffuse
00:05 gaze__ and you get a large molten blob
00:06 furrywolf yep
00:06 gaze__ http://en.wikipedia.org/wiki/Thermal_diffusivity
00:06 gaze__ this defines the time/length scale we're working with.
00:07 rrywolf welds, and knows how quickly materials suck away all your
00:07 gaze__ 20W is a good start for SLS in plastic.
00:07 gaze__ I like stereolithography because there's no diffusion
00:08 gaze__ if you clean your beam up properly, you'll cure a point.
00:08 gaze__ well... your beam is a gaussian so you cure a fuzzy point that moves outwards slowly
00:08 gaze__ but yeah... it ain't diffusion.
00:08 furrywolf assuming your resin absorbs the laser nice and quickly, and doesn't go too deep as soon as you try making an overhang...
00:09 gaze__ that's controlled by the opacity of your resin... which is very easy to formulate
00:13 furrywolf are there optical plastics transparent at the wavelength of your laser?
00:14 gaze__ oh sure... and I can pick a higher wavelength laser and change my resin/photoinitiator
00:15 gaze__ plastic optics could work well
00:15 furrywolf tried finding a cheap plastic f-theta lens?
00:15 gaze__ they only make 1D ones.
00:15 gaze__ for laser printers
00:16 gaze__ hahaha....
00:16 gaze__ someone should put up the money to diamond turn the injection mold for one
00:16 gaze__ then you could make tons for cheap.
00:16 furrywolf yep
00:17 gaze__ but then you want cheap galvanometers and all sorts of other things.
00:17 gaze__ so it's like eh.
00:17 furrywolf and as I said earlier, you can't keep your deflection small enough to use a 1d lens after each mirror without aiming off the sides of the second lens?
00:17 gaze__ I don't think you can make the optics work like that.
00:20 furrywolf hrmm... the off-angle beam into the second lens may introduce distortion.
00:20 rrywolf isn't an optics ex
00:22 gaze__ yeah... f-theta lenses are weird
00:24 gaze__ anyway. It's nice having variable focus for stereolithography
00:24 gaze__ so I can do the infill quicker
00:24 gaze__ by blurring the beam and just going over the inside
00:24 furrywolf http://www.alibaba.com/product-gs/437736130/F_theta_scan_lens_infrared_scan.html?s=p $100-$400, minimum order 1pc.
00:25 gaze__ infrared yo.
00:25 gaze__ need UV
00:25 furrywolf oh yeah, you're doing uv.
00:25 rrywolf should read ha
00:25 rrywolf is t
00:26 gaze__ 1064 is popular because it's what just about every nd:yag marking laser runs at
00:26 gaze__ so factories have 'em
00:26 gaze__ for putting logos on little things... or cutting flex circuits or whatever
00:27 furrywolf http://www.alibaba.com/product-gs/609494164/CO2_ZnSe_F_theta_scanning_lens.html oh, shiny...
00:27 gaze__ aw yeah
00:28 gaze__ that'd be great for a selective laser sintering setup
00:28 furrywolf still $100-$400. :P
00:28 furrywolf and 1pc minimum order
00:28 gaze__ yeah that's super cool
00:28 gaze__ yay china!
00:29 furrywolf well, they're not intrinisicly more expensive than any other aspherical lens as far as I can tell...
00:29 furrywolf just they're sold to a small market of high-priced machines, so they can charge a lot for them.
00:32 furrywolf http://www.ebay.com/itm/F-Theta-Ronar-Lens-532-nm-for-Laser-Engraving-Systems-100-/180942701659?pt=LH_DefaultDomain_3&hash=item2a2106845b
00:32 furrywolf can't beat that price. :)
00:33 gaze__ yeah no kidding
00:33 gaze__ 532 is too long I'm afraid
00:33 gaze__ http://www.ebay.com/itm/Moticont-Linear-Voice-Coil-Motor-LVCM-025-038-04B-/120953702329?pt=LH_DefaultDomain_0&hash=item1c296707b9#ht_852wt_1393 ugh
00:33 gaze__ why does this damn thing have to be so expensive.
00:34 furrywolf http://www.ebay.com/itm/RODENSTOCK-laser-lens-f-50mm-488nm-F-THETA-/221074046698?pt=LH_DefaultDomain_0&hash=item33790a3eea 488 any better?
00:34 gaze__ oh man
00:34 gaze__ that could cut it maybe
00:34 gaze__ not sure
00:35 gaze__ 2 inch focal length...
00:35 furrywolf I need to get something znse... just because it's such a perfectly shiny color. heh.
00:35 gaze__ not sure what sorta field that gives me
00:36 furrywolf could also try getting a quote from some of those chinese manufacturers.
00:38 furrywolf http://www.alibaba.com/product-gs/427042732/best_quality_Co2_znse_F_theta.html there's a lot of them.
00:39 furrywolf "The items above are designed all by ourselves. Samples are available."
00:39 furrywolf SAMPLES.
00:39 furrywolf if you can get one free... :)
00:40 furrywolf "I am the head of R&D for GazeINC rapid prototyping systems, and am investigating lenses for use in our upcoming stereolithography offering..."
00:42 furrywolf http://www.alibaba.com/product-gs/549261794/F_theta_CO2_scanning_lens_monolithic_.html min order 10pcs, but they'll sell the bare lens for under $50...
00:42 rrywolf curls up on katsmeow for bed
00:44 gaze__ have you ever ordered on alibaba?
00:48 dumbass the longer distance tween laser and servo deflection lens assy, the less the distance aberration
00:48 GuShH furrywolf: I've tried to sample from alibaba sources... it's a bad idea.
00:49 GuShH they harrass you and request all sorts of crazy information such as "which port would you like the parts to be sent to" ... it's a sample, why would I want a full blown import operation!?!?
00:49 dumbass at 4ft the diference tween middle and top of mirror is very very small
00:50 dumbass so calc using the middle aimming, and the difefrence ween middle and top or bottom is the +/-
00:50 furrywolf no, I haven't ordered there.
00:51 furrywolf heh, yeah, make your optical path very long, then the focus change is minimal... bounce it around a bunch of mirrors first. :)
00:51 furrywolf bbl, bedtime
00:53 gaze__ I'm gonna voicecoil the shit out of this thing...
00:54 furrywolf old speaker. :P
00:54 furrywolf bbl
03:59 gaze__ yo. Anyone know how the lens in most cdroms are held in place? they definitely float in a voice coil sorta thing but I'm wondering what holds them in place
03:59 gaze__ some sorta springymajig
04:11 ShH idly stabs ga
05:23 rue_shop gaze__ wisker springs
07:04 fish0 Hello does anybody have a list with the allowed line plates for the robocup junior rescue A league?
07:04 fish0 Thank you for your answer
07:16 fish0 hello is anybody here?
07:16 fish0 hello rue_shop2
07:23 rue_shop2 uuuuu
11:48 rrywolf stretches out on kat and y
11:53 ckkitten pettles furrywol
12:01 furrywolf mrrf :)
12:23 hackkitten :D
12:24 anannie hi hackkitten
12:25 hackkitten hi anannie :)
12:26 anannie hackkitten: What are you working on?
12:30 hackkitten just doing some programming
12:42 furrywolf and petting!
12:52 ace4016 heavy petting? naughty! http://www.youtube.com/watch?v=3Ml4dA8TZTU
12:53 theBear our pets are well looked after, they aint heavy
12:55 ace4016 hehe
12:59 theos hi
12:59 HKCMD hi
12:59 tobbor Hello HKCMD
12:59 HKCMD hello tobbor
12:59 theos tobbor is the resident bot :)
13:00 HKCMD ohhh
13:09 furrywolf bbl, going to head off to the local flea market, get breakfast, then stop by my boss'es house and tell him that not only am I quitting, I'm taking all the customers with me... not necessarily in that order. :)
13:09 dumbass k
13:09 dumbass wait
13:09 dumbass i vote against the quitting part
13:10 furrywolf heh
13:11 furrywolf well, the largest company we contract for has called me up, and said they're sick of dealing with my boss... and if I go and get a motor carrier permit, etc, all the stops are mine.
13:11 theBear hmm, seperate from that friend that offered you their business last week ?
13:11 dumbass IF you get a permit
13:11 furrywolf theBear: related. she also contracted for the same company.
13:11 dumbass get the permit first
13:11 anannie furrywolf: Get the permit first and then go for it.
13:11 ace4016 furrywolf, make sure you're not in a position to get sued
13:12 theBear interesting... good that they have that opinion of you
13:12 dumbass you got to cya
13:12 dumbass c.y.a.
13:12 anannie and I agree with ace4016... Get a lawyer and read the contract to see if there are any exit clauses. Don't be rude either. Just be polite and exit without prejudice
13:13 ace4016 well, companies can sue ex employees that steal customers, even if the customer wanted the employee and didn't want to deal with the company
13:13 Skwint don't burn bridges unless you really need them burnt :p
13:13 furrywolf well, I'm not telling my boss I'm quitting, today at least. I'm telling him I've been offered the route of the friend that retired, and will likely take it. her route is in the morning, and the route I run for my boss is in the afternoon. I plan to keep doing his route for him, for now at least.
13:13 dumbass soon as boss learns he lost customers, the war will be on
13:14 furrywolf he's not stupid, and will realize that my working the other route directly will mean I could also run his stops directly, and he knows how much he's liked.
13:14 dumbass furry, if yu get sick now, and stay in bed 2 days, your boss will cover your route, but if you are on your own, you lose the business
13:15 rrywolf wishes kat would stick with normal n
13:16 furrywolf and, yes, that's correct. but I'm not making enough money working for him.
13:16 furrywolf I can barely keep the bills paid, and I'm not managing to save any of it.
13:16 furrywolf I need a new or second job.
13:16 dumbass i earned this nick by believing a robot is a good tool to take down dead trees
13:17 anannie dumbass: You're katsmeow?
13:17 mbass
13:17 anannie dumbass: Can I PM? (and you aren't dumb)
13:18 dumbass yes, but i was about to go get lunch,, must be midnite for you
13:18 theBear hehe that's yet to be seen, unless i missed a nickchange and someone is being a sissy again
13:18 anannie dumbass: Yeah... I just wanted to show you something
13:18 dumbass k
13:18 mbass looks sideways at the
13:18 anannie furrywolf: What you need more than anything is a business partner. Find a co-founder first, codify the agreement on paper, then quit and then expand
13:18 furrywolf fuck no.
13:19 furrywolf relying on other people is a big mistake, as I've learned way too many times.
13:19 theBear hehe, a sideways look confirms nothing
13:19 dumbass furry, if your truck drops a transmission, your business is toast
13:19 theBear oh, /me reads harder
13:19 theBear someone IS being a sissy again, cheer up kitty <best attempt at a real smile>
13:20 anannie furrywolf: Relying on most people is, but you have to rely on the right people to make the business work.
13:20 dumbass your customers are buying a service, not you specifically
13:20 furrywolf so I should continue being a wageslave living from paycheck to paycheck with no savings, borrowed internet access, etc forever - what a good plan!
13:20 anannie furrywolf: A business can't exist in isolation or in vacuum
13:20 moriarty can anything exist in isolation?
13:21 anannie furrywolf: You need people. Find someone who you can trust and work with them to build it up
13:21 moriarty redundant statement is redundant
13:21 anannie It's a risk, but it's a risk you can take
13:21 dumbass furry, get the permits, take the morning route as a 2nd job, say nothing to your boss, get breakfast, consider a 2nd driver and get a vehicle in reserve
13:21 anannie moriarty: The big bang.
13:21 furrywolf anannie: any time you work with someone else, they think you should do the work while they get the benefits.
13:22 anannie furrywolf: That isn't always true. Again it's about who you pick and how you pick them
13:22 furrywolf dumbass: I have to say something to my boss, as part of the work my retiring friend did was picking my boss'es stuff up at the airport, and he'll need to know I'd be doing that part.
13:22 furrywolf anannie: do I know you? do you always sound like a disney movie?
13:22 dumbass oh
13:23 furrywolf right now, I don't have a suitable vehicle to take any of the stops I do for my boss on myself.
13:23 furrywolf my friend's route is local, ~20 miles... the route I do currently is 155 miles.
13:23 dumbass package deliver with no vehicle, boy will you be tired
13:24 furrywolf I can do my friend's route with my or a borrowed vehicle. I've been working on restoring a postal jeep for someone, and she says I can borrow it for a while.
13:24 furrywolf so my plan is to take on my friend's route, while still working for my boss. the times do not overlap.
13:25 furrywolf but he needs to be told about this, and he's smart enough to see what it implies.
13:25 dumbass it implies you need more money
13:25 anannie furrywolf: http://paulgraham.com/startupmistakes.html
13:25 furrywolf oh, did I mention he wants to try getting my friend's route too, and was told to sod off by the people who don't like him? heh.
13:26 dumbass heh, Tiggr mined all of paulgraham.com last week
13:26 furrywolf anannie: there's a difference between starting a corporation and being an independent contractor for a courier business.
13:27 furrywolf the startup costs are under $500, for one...
13:27 furrywolf and this business is typically done entirely by independent contractors. employer-employee relationships, like I have with my boss, are rare.
13:27 anannie furrywolf: At their core both are still businesses and are propositions at the start that need to lure people into investing time and energy which is always the highest
13:27 anannie furrywolf: Maybe you can change that?
13:28 furrywolf did that even make sense?
13:28 furrywolf I take it you're not familiar with how the courier industry works.
13:28 moriarty why would anybody want to be courier?
13:28 moriarty that's one heck of a capital intensive
13:29 ace4016 intensive?
13:29 ace4016 investment?
13:29 furrywolf customers rarely contact independent couriers. instead they contact large regional or national companies. these companies don't have employees, instead they have independent contractors in the areas they service.
13:29 anannie furrywolf: Think about it. What you have is a largely unorganised market that is cutthroat and clearly customers want service and something more than just the usual independent contractors route. Clearly if you invest in a few things and offer an organised solution that is a) reliable, b) personalised and c) convenient then you might get somewhere
13:29 dumbass lotta mileage on vehicles, lotta fuel burned, and it MUST be reliable
13:29 furrywolf anannie: are you taking some form of management-related classes and repeating what you're reading?
13:29 anannie furrywolf: Then those corporations are your customers
13:29 anannie furrywolf: No
13:30 furrywolf the actual startup costs to be an independent contractor for one of these companies are minimal. a business license, motor carrier permit, insurance, and airport permit, plus a vehicle.
13:31 furrywolf I currently do work for one of these companies, with my boss as a middleman. they want to cut my boss out of the loop, and have been saying this for a while.
13:31 anannie furrywolf: you're forgetting the time and energy taken to do this. If you have an organised response within this then you can turn this around and make it into something big
13:32 furrywolf wtf is an "organized response" to "time and energy"?
13:32 furrywolf and how do you expect me to make "something big" out of being a lowly courier contractor in a declining market?
13:33 ace4016 lol
13:33 anannie furrywolf: Right now it's just you running around doing parcels. Imagine if you could properly organise people with a bunch of GPS phones and an apps that tags them and uses something like A* plus a bunch of rules to determine the cost effectiveness of a certain route to find good enough solutions?
13:33 furrywolf that's what the national companies that contract us do.
13:33 furrywolf maybe I'll do that someday. not now. right now I'm just going to be a lowly IC.
13:33 dumbass annie, you forget that he has no license or contracts to do this now
13:34 anannie furrywolf: You should be able to squeeze a profit out of that by being reliable and the market in itself won't decline until there are mass robotic cars... People will always have to move things from place to place.
13:34 anannie dumbass: Oh. I'll stop.
13:34 dumbass and, afaik, his truck isn't optomised for packages, and it gets 6mpg
13:34 furrywolf viritually the entire courier industry is ICs working for these larger companies. I'm not doing something new or untried here.
13:35 anannie furrywolf: But you could use this as a stepping stone to do something great over here...
13:35 dumbass UPS is ICs?
13:35 furrywolf I don't think ups is, but fedex is.
13:35 furrywolf dhl is too.
13:36 furrywolf fedex drivers own their own trucks and work as ICs.
13:37 furrywolf anannie: most of the courier industry (as opposed to parcel delivery) is paperwork and medical. the paperwork part is declining as more things go paperless, while the medical part is declining as diagnostic equipment becomes cheaper and more hospitals and clinics do more in-house.
13:39 furrywolf for example, I do a lot of bank work. checks need to make it to the clearing house system every day. we lost bank of america last year, as they started scanning then storing and shredding the paper checks, sending them electronically instead of by courier.
13:39 dumbass anyhow, you need to build to this, can you make money if you pay $4/gal for fuel and get 6mpg? are you willing to be up all nite changing truck parts to be sure the thing runs all day tomorrow? can yu carry 10 200lb boxes?
13:39 ace4016 furrywolf, well, if things start becoming localized for products, local parcel couriers might be more desireable if the price is right...although, slightly unlikely to happen any time soon
13:39 ace4016 cupcake courier!
13:39 furrywolf 200lb? I do paperwork. 20lb is RARE. most of it is in little fireproof pouches.
13:39 dumbass k
13:39 furrywolf and I don't plan on driving my truck.
13:39 furrywolf as I already said, I plan on borrowing someone's mail jeep, until I can afford a good vehicle.
13:40 furrywolf probably look for a well-used minivan or compact suv.
13:40 dumbass you still need to keep it running
13:40 dumbass and then there's commercial insurance
13:40 furrywolf if it becomes non-running, then I can take my subaru or my truck until I fix it.
13:40 dumbass k, long as you got your butt covered, i'll all happy for you
13:41 ace4016 go for diesel :P
13:41 furrywolf commercial insurance is $350/year for the business policy with 2mil general liability, $84/month for the automotive policy with 2mil property damage and 2mil personal injury. already got the quotes.
13:41 dumbass diesel costs too much here now
13:41 furrywolf diesel is good because you can run chuff fuel at significantly lower $/gal if you don't mind some work.
13:41 furrywolf two of my friends have been running entirely on used motor oil for a year or so now...
13:42 anannie furrywolf: Oh I understand. Can you move to parcels? If you think about it people need to move matter around everyday in a city from moving houses to restaurant deliveries to sending out gifts and personal paperwork... There has to be an opportunity over here.
13:42 furrywolf I don't want to do parcels.
13:42 dumbass diesel has been well over gasoline prices in the Al-Ga-Fla area for a couple years
13:42 furrywolf parcels pay MUCH less, are much more work, and are in an industry with much stiffer national competition.
13:43 anannie furrywolf: Oh.
13:43 furrywolf banks and hospitals pay more because of the increased responsibility their cargo needs. if you're carrying every check deposited at the branch that day, or every blood sample a hospital drew that day, they want it well taken care of, and on time.
13:44 furrywolf working for my boss, I don't see this "more", and make the same $11/hour no matter how much he's getting paid. he has a new house, new off-the-dealer-lot car, etc, and doesn't run a route himself.
13:44 dumbass one of the courier companies here requires it's carriers have concealed firearms permits, and carry
13:45 furrywolf while I have to borrow internet access because I can't pay the bills.
13:45 anannie furrywolf: That makes sense, what about restaurants? Surely they are in a service business as well and a lot of restaurants want greater coverage...
13:45 furrywolf I don't do cash, just paperwork, so they don't need me to have a gun. no one wants to steal proofwork.
13:45 furrywolf ... huh?
13:46 furrywolf you think pizza delivery wolfy is a useful job option? lol
13:46 furrywolf there's a reason that job only goes to 16 year olds who quit in six months.
13:46 anannie restaurants do home delivery right? What if you offered a service in the longer run to these restaurants that gives them a no-brainer day to day delivery service for a variable rate and you do it efficiently again by using a bit of technology
13:47 dumbass do only high end resturants, those that would do catering anyhow, for instance
13:48 anannie dumbass: Yup. A lot of restaurants struggle to make money so for them something like this would be a boon because it would remove the cost of supporting infrastructure
13:48 dumbass i am concerned you end up jobless, due to business drying up, or you being sick and customers leaving, or vehicle downtime, or whatever,, and i think that's what everyone else is saying too, do your startup business without leaving your current job
13:48 furrywolf the only restaurants that do home delivery are pizza joints. there is no profit to be made in home delivery. no customer will pay more than a small percentage of the food cost for delivery.
13:49 furrywolf does anyone fucking read what I wrote?
13:49 dumbass yeas
13:49 furrywolf <furrywolf> so my plan is to take on my friend's route, while still working for my boss. the times do not overlap.
13:49 anannie furrywolf: there's an opportunity over here and I really believe that you can capitalise on it
13:49 dumbass BUT you said you were also scheduling breakfast and quitting for today
13:50 furrywolf <furrywolf> well, I'm not telling my boss I'm quitting, today at least. I'm telling him I've been offered the route of the friend that retired, and will likely take it. her route is in the morning, and the
13:50 furrywolf route I run for my boss is in the afternoon. I plan to keep doing his route for him, for now at least.
13:50 anannie furrywolf: Yes I did. I that that you're missing out on an opportunity. I'm reading up right now and clearly this industry is ripe for disruption. The fact that people think that's crazy and the conventional way is so entrenched means that there *might* be money to make over here if someone can figure out the right sequence
13:50 furrywolf anannie: the opportunities in the courier business are minimal at best.
13:51 dumbass and what about breakfast?
13:51 furrywolf the entire industry is shrinking, and there's tons of large companies that are losing stops trying to pick up every shred of business that they can.
13:51 furrywolf I do not plan on this for a long-term job, a major business, or something I'll retire on.
13:51 furrywolf I plan on a short-term job with no advancement prospects that I can use to pay the bills and hopefully build up some savings.
13:52 dumbass that's prolly what Gates said too
13:52 dumbass small job for Intel, then we get on with the real work
13:52 dumbass and what about breakfast?
13:53 furrywolf new, expanding market != old, declining market.
13:53 dumbass no ne but me is addressing that, i vote you do that
13:53 dumbass i vote i do breakfast too, now that it's nearly 2pm
13:54 furrywolf the only reason I'm getting this job is because my friend is retiring and sent her customers to me. otherwise it's very hard to even get a foot in with all the companies trying to pick up work in a declining industry.
13:54 furrywolf if she were will working, the only option would be to pick up new customers (hasn't happened in years, for anyone), or to try starting by taking other people's stops.
13:55 furrywolf yes, breakfast does sound good. I've spent, what, an hour explaining all this?
13:55 furrywolf bbl
13:55 dumbass me too, bbl, i need nourishment
15:15 furrywolf well, boss isn't too annoyed, and he says I can keep doing his work in the evening.
15:34 furrywolf what to do now... can't do anything towards the business today, being sunday. work on the garden? prune my giant pepper plant that has reached the top of the greenhouse (8ft over the pot!)? work on vehicles? work on water heater? waste time on the internet?
15:35 theBear heh, just imagine what i would do, and do the opposite, should be positive and productive day <grin>
15:36 rrywolf has no idea what a bear does in its spare
15:36 rue_shop4 he is australlian
15:37 furrywolf drink beer in a shed?
15:38 rue_shop4 kinda right the answer was 'hide from the heat'
15:38 e_shop4 demonstrates his hi
15:49 mbass does dumbass th
15:51 Tom_itx yes they do
15:51 Tom_itx stupid is as stupid does says Forest Gump
15:51 Tom_itx but we know better than that for you
15:51 dumbass then how is using a robot to cut dead tree limbs a bad idea?!?
15:51 Tom_itx make one
15:52 Tom_itx i'm not sure i could
15:52 dumbass how is using a robot to remove a tree leaning at the house a bad idea??
15:52 dumbass why make one? i'm told it's a bad idea
15:52 dumbass i'd prolly get banned from here for having one
15:52 Tom_itx i doubt it
15:53 Tom_itx i have power of veto
15:53 dumbass i can't tell from humans
15:54 dumbass at onle ppoint in my drive, i can see 4 dead limbs over the driveway, 2 i am really concerned over, and i can see 2 100% dead trees that need to come down
15:54 mbass is so confused about a robot to do something good, inexpensively, keeping humans safe from harm, a bad
15:55 dumbass especially in a robot channel
15:57 Tom_itx is the whole tree bad?
15:58 dumbass i got two dead trees i need cut down from the top down
15:58 dumbass bark falling off, etc
15:58 Tom_itx you can't make them lean the right way and just cut them down?
15:58 dumbass i got one leaning badly near my hose, one on the property line leaning
15:59 dumbass sure, if i wann aput a ladder against and climb high enough to tie a chain
15:59 Tom_itx i have used a bow an arrow with a string to pull a rope to tie near the top
15:59 dumbass if it was a little off, not a problem, but it's dripping dead limbs, and leaning a lot
16:00 Tom_itx and secured that to a vehicle while cutting
16:00 dumbass rope won't do, need steel cable or chain, and tons of pull (winch), it's a big tree and leaning a lot
16:00 dumbass towards the house, etc
16:00 dumbass no, this would pull everything but th etruck along with it
16:01 dumbass and, it's off the drive, the truck would sink in the mulch, i have a winch i can tension up a guide chain to another tree
16:02 dumbass it's a recurring need, to have a robot up in a tree instead of a fragile human
16:02 furrywolf explosives. use bow and arrow to get a rope around the tree at the right height and use it to pull a loop of detcord around the tree.
16:03 dumbass good idea, ups some some detcord to me
16:03 furrywolf I think you have to use fedex. :)
16:03 dumbass if they drop it, it will be the last time they drop something
16:03 furrywolf lol
16:03 Tom_itx may solve a couple of your issues
16:04 dumbass yep
16:04 rue_shop4 I have a 2.2Ghz chip I can fit on this new machine, its got an X on it, so technically,its tested bad, but lets see
16:04 rue_shop4 think the heat sink clip will break on me taking the current one off?
16:04 e_shop4 expl
16:06 furrywolf yes
16:09 rrywolf thinks kat should build said tree-climbing robot, and use it to prove naysayers w
16:10 furrywolf I'm not sure how you'd build it, though... maybe a spring-loaded snake-like thing with spiked wheels on the inside, that wraps itself around the tree then climbs vertically, then moves sideways to spiral/screw around limbs?
16:11 Squint snakes climb trees just by having scales
16:11 Squint they don't go round the tree, they just wind their way up it
16:12 Squint If I had to make a tree climber I'd go for lots of grappling hooks on winches
16:19 furrywolf as in, you toss up the hook, then it climbs the line? heh
17:12 rue_shop5 wow, a 1.8Ghz machine cant smoothly play youtube videos
17:12 furrywolf save, play with player.
17:12 furrywolf flash is the problem.
17:12 furrywolf mplayer
17:13 rue_shop2 still, like 1.8G
17:14 rue_shop2 I cant seem to switch P4 procesors between boards, I have a board that says it can take a 2.4G and when Iput that in it wont do nuthin
17:24 rue_shop5 I ahve one machine with a 2.4G processor in it, and its got somekinda memory controller problems
17:24 delinquentme Ummm bolts with rubber tips on them .. ones which can be used as feet for something placed on a desktop
17:28 delinquentme found it!
17:28 delinquentme OK nowwww
17:28 delinquentme something that I can pout concrete into ... and then bolt to something
17:28 delinquentme like a hollow square tube would be perfect
17:28 delinquentme PVC would be an option but squares easier to drill into
17:41 e_shop5 m
17:45 delinquentme square plastic tubing!
17:50 atom1 they make cardboard forms
18:00 delinquentme not bad!
18:00 delinquentme min order: 5000 feet
18:00 delinquentme =/
18:06 Tom_itx local concrete supply
18:11 delinquentme plastic extrusions?
18:12 delinquentme im thinking something like 2"*2" would be perfect
18:12 delinquentme HMMM how much do beebees cost!?
18:33 atom1 what for?
18:33 atom1 what about shot
18:33 atom1 you can get that by the bag
18:40 delinquentme yeahh!
18:40 delinquentme atom1, i just looked it up
18:40 delinquentme cocnrete is still way cheaper
18:40 delinquentme but shot is cool bc it doesnt need to dry
18:40 delinquentme and it will certainly pack evenly
18:41 delinquentme $0.34/lb vrs $1.47/lb
18:58 rue_shop2 cheaper than what?
19:09 atom1 sand?
19:10 atom1 you haven't said what you're making
19:32 dumbass there's still enough water in the dry creek to pump 1/2 gallon per minute, or 700 gallons per day
19:36 dumbass that's 21 days with no rain at all, and that wasn't enough to even dampen the ground
19:51 gaze__ rue: I hear you've built a voice coil actuator?
21:43 dumbass it was an avr operated electric selenoid pulling against a spring, real precise positioning
21:44 dumbass if you replace the iron core with a magent, it's prolly push as well
21:45 dumbass tobbor, !find selenoid avr
22:23 dumbass .
