00:00 katsmeow-afk tires are 3500lbs each
00:00 rue_house 2.5 ton tires?
00:00 rue_house that cant be good on gas
00:00 katsmeow-afk so 7000lbs max rear axle, and if one pops on the highway, they all pop
00:01 rue_house how big is the bed?
00:01 katsmeow-afk 12mpg, diesel , but it beats the Suburban, which gets 12mpg even empty and won't get up my driveway with a load on it, and wouldn't haul the pontoon boat up that hill out there from a standing stop
00:02 katsmeow-afk 8wide by 11.5 long
00:02 rue_house wow
00:02 rue_house air or hydraulic brake?
00:03 katsmeow-afk the Suburban will spin it's tires, but doesn't have gears for torque
00:03 rue_house I think my truck is only 14 feet
00:03 katsmeow-afk hydraulic over hydraulic
00:03 rue_house huh
00:03 katsmeow-afk hydraulic pump powers the antilock system, with hydraulics down to the calipers
00:04 katsmeow-afk separate systems
00:04 katsmeow-afk the pump takes a lube-type oil, the brake side takes a brake fluid
00:05 rue_house gnight
00:05 katsmeow-afk oh
00:05 katsmeow-afk sorry
00:05 rue_house I consider my weekend ruined
00:05 katsmeow-afk but you got septic system!
00:05 rue_house sorry?
00:05 rue_house yea, the septic system ruined my weekend
00:06 katsmeow-afk sorry i entioned the truck because now you're going to bed
00:06 rue_house all I got out of it was a planted tree, a leveled driveway, and a pipe across the driveway for the car detector
00:06 rue_house no I have to go to bed anyhow
00:06 katsmeow-afk beats what i got
00:06 rue_house I overate and I been falling asleep for hours now
00:06 katsmeow-afk k, gnites
17:00 tsmeow-afk calls up AT&T and asks for telegraph ser
17:59 katsmeow-afk Last month Nokia announced it was to stop manufacturing mobile phones in Europe, instead relocating to Asia at a cost of 4,000 jobs.
18:51 zhanx ok got broadband again
18:52 zhanx and loving my 50$ tv
18:52 zhanx the cable guy was confused when he came in
18:52 zhanx which tv do i hook up
19:18 rue_house picture and picture
19:18 rue_house BOTH OF THEM
19:37 katsmeow-afk UPS fucked up again, lost a package
19:43 SolarNRG Do any of you guys know what PROMAT material is?
19:43 Tom_itx nope
19:43 SolarNRG I can find 20mm sheets of the stuff, but what do I do if I want a BLOCK of it?
19:44 katsmeow-afk you can't, but i'l let the guys answer
19:46 tsmeow-afk closes the webpages on the s
19:59 tsmeow-afk s
20:00 katsmeow-afk //join #DoNotNeedPenisToAnswerQuestions
20:00 katsmeow-afk oops
20:19 zhanx hmmmm
20:20 zhanx SolarNRG: glue it
20:26 SolarNRG What glue can withstand 2000 degrees C?
20:29 rue_house SolarNRG,
20:29 rue_house I think the melting point of steel is 1700c
20:30 rue_house so it would have to be a ceramic
20:31 rue_house 'steel melts at around 1370?C'
20:38 useless-afk the rubber promat cannot stand 2000C anyhow
20:41 rue_house I dont have much time I should get my pcb etched
20:41 rue_house kat, your name fell off again
20:41 e_house hands kat some super
20:41 e_house tries a
20:41 rue_house oh dear...
20:41 e_house tries to let go of the crazy
20:42 useless-afk SolarNRG was asking questions and he wanted answers only by males
20:42 rue_house no, he is being afk as usual
20:42 useless-afk i was therefore useless
20:42 rue_house gee your imaginitive
20:42 e_house tries to pry off the little bottle of super
20:42 useless-afk [19:34] <SolarNRG> Do any of you guys know what PROMAT material is?
20:42 useless-afk [19:34] <Tom_itx> nope
20:42 useless-afk [19:34] <SolarNRG> I can find 20mm sheets of the stuff, but what do I do if I want a BLOCK of it?
20:42 useless-afk [19:34] <katsmeow-afk> you can't, but i'l let the guys answer
20:43 eless-afk parts #DoNotNeedPenisToAnswerQuest
20:44 rue_house kat, dont get all offended cause he said "guys"
20:44 useless-afk ok
20:44 rue_house he meant everyone
20:44 rue_house he just wasn't being politically correct
20:45 useless-afk i was going to get some of that stuff for an outbuilding in Fla, till i realised i could't move there, that's how i know about the stuff
20:45 rue_house can it really withstand 2000c?
20:45 rue_house wait you already said it couldn't
20:45 useless-afk i said it cannot
20:45 rue_house wonder what he's up to
20:46 useless-afk prolly trying to nuke cans in a microwave again
20:57 katsmeow-afk i wonder how many millions of watts a normal aluminum waveguide handles without any warming at all
21:02 katsmeow-afk Rectangular waveguides are used routinely to transfer large amounts of microwave
21:02 katsmeow-afk power at frequencies greater than 3 GHz. For example at 5 GHz, the transmitted power
21:02 katsmeow-afk might be one megawatt and the attenuation only 4 dB/100 m.
21:04 katsmeow-afk For waveguides with conducting walls, the transmission losses are due primarily to
21:04 katsmeow-afk ohmic losses in (a) the conductors and (b) the dielectric medium filling the space between
21:04 katsmeow-afk the conductors and in which the fields propagate.
21:07 rue_house swo its a good idea to evacuate waveguides?
21:07 katsmeow-afk welll,,, depends a lot on the power, size, and freq
21:08 katsmeow-afk replacing regular air with something else is often done, like dry air, nitrogen, argon, etc
21:08 katsmeow-afk the larger waveguides cannot have a vacumn in them, they'd collapse
21:09 katsmeow-afk some waveguides are pressurised
21:09 rue_house not if you have the same pressure on the other side of the waveguide
21:09 katsmeow-afk some bench equipment is pressurised with dry gasses
21:09 katsmeow-afk umm, yeas, but who will run a vac-filled wavguide thru a vacumn camber just to get a waveguide?
21:10 katsmeow-afk oh, right, the military
21:10 rue_house (:| it seemed like a sound idea
21:10 e_house goes into the corner and c
21:11 katsmeow-afk if you consider a klystron or a cavity magnetron to be waveguides, since they ARE tuned by their physical shapes, they are vacuumns
21:11 e_house snif
21:11 tsmeow-afk pours rue some cookies, fudge, and
21:11 rue_house really?
21:11 katsmeow-afk really
21:11 rue_house well, ok then...
21:12 katsmeow-afk so is a TWT, but less so
21:12 rue_house my fav is the reflex klystron
21:12 rue_house klystron is a cool name, and 'reflex' just makes it cooler
21:13 katsmeow-afk solardop.. er solardude would have more luck melting his alumynum at 100khz than 2.4ghz
21:13 rue_house yea
21:13 rue_house induction furnace
21:13 katsmeow-afk yeas
21:14 rue_house if its costs $5 in diesel to melt 3L of aluminum, and electricity is cheaper and more efficient than diesel...
21:14 rue_house then it shoudl cost less than $5 to have an induction furnace make the same amount
21:15 katsmeow-afk 3L is a lot of aluminum for a hobby smelert tho
21:15 rue_house yea, I dont usually fill 'er up
21:15 katsmeow-afk speaking of alum,, i got another dead hd from the move back to here
21:16 rue_house I'd need a proper clay pot
21:17 katsmeow-afk i dunno, $5 in electricity at 15 cents per kwh is only 10kw for 3.33 hours
21:17 rue_house 10kw
21:17 rue_house 240V 41A
21:17 rue_house eeek
21:18 rue_house wait
21:18 rue_house thats not what we pay
21:18 rue_house oh I should go get the bills
21:18 rue_house :(
21:18 rue_house dont wanna
21:45 tsmeow-afk ponders dinner: pasta or ramen ,,,, sorta the same t
21:52 katsmeow-afk drat, Global Resource Corporation folded
22:29 katsmeow-afk CloudSat's Cloud Profiling Radar (CPR) is a 94-GHz klystron
22:52 rue_shop that must be TINY
22:52 rue_shop ok I'll check the overload pcb tommorow
22:52 rue_shop make sure I transferred everything
22:52 rue_shop 2.5x2.5
22:53 rue_shop well 2.5x2.3"
23:07 katsmeow-afk regarding the KeysoneXL canada-usa oil pipeline to move canadian oilsands oil to Texas : ""Gulf Coast refineries can then access lower-cost domestic production and avoid paying a premium to foreign oil producers,""
23:08 rue_house nobody in canada wants that pipeline
23:08 rue_house accept the primminister
23:08 rue_house who is an idiot
23:08 theBear except
23:09 tsmeow-afk wants to hear why
23:09 rue_house hehe
23:09 rue_house cause we know it'll be an environmental disaster that will not profit us in the least
23:10 katsmeow-afk the pipe?
23:19 katsmeow-afk this is a classic example of predatory pricing: there's so much oil that they need massive new $billion pipelines to move it to market, yet all fuels are prices so high
23:20 katsmeow-afk there's only one reason for the pipeline: so canadian companies can sell at world-market prices to countries on the Atlantic ocean
23:20 katsmeow-afk else they'll haveto sell at lower prices inside Canada
23:52 katsmeow-afk The Wyoming House of Representatives advanced the legislation on Monday, but eliminated language calling for plans to implement its own military draft, army and acquire an aircraft carrier.
23:54 katsmeow-afk what would Wyoming do with an aircraft carrier?
23:54 katsmeow-afk afaik, it has no water at all deep enough to float one, and is nowhere near enough water to get one up to speed
