00:04 GuShH rue_mohr: ain't buying a devilbiss any time soon, can't afford it, can't find them either.
00:04 GuShH well, theres a local supplier for that brand, but they're far away.
00:05 GuShH they mostly carry powdercoat equipment anyway
00:08 katsmeow-afk i actually removed and replaced a post under the shower, to fit the ro pump where i wanted it ,, the post is in the utility room below the top floor bathroom
00:13 katsmeow-afk so if i let the ro pump stop up the brine flow, the incomng pressure isn't removed from the ro filter, but it cannot pump out any clean water once it reaches incoming water pressure, so there is no (or is there?) TDS creep?
00:16 e_mohr tries to get his gui workin
00:16 tsmeow-afk doesn't do nix, so is sorta useless a
00:17 rue_mohr if this had happened to windows I couldn't be talking to you now
00:17 rue_mohr I'd still be trying to find drivers
00:17 rue_mohr for my network card
00:17 rue_mohr so I could download drivers
00:17 katsmeow-afk i didn't say which Os was betetr, only that i dunno nix
00:18 rue_mohr I cant figure out what I was using as a window manager
00:18 katsmeow-afk no hints in doing a bruteforce string serch of the ssd or hd image?
00:18 rue_mohr has to be enlightenment
00:40 rue_house see if I can get thing working eough to buy today ebay item
00:51 rue_house ok, got htat
01:27 rue_bed ok, well, I'm closer
01:37 rrywolf flops next to katsmeow-afk for bed
01:40 katsmeow-afk ok, who melted the ice cream i left out while plumbing?
01:40 katsmeow-afk and why is it now 1:30am ??
01:40 rrywolf tucks kat in, then flops on top of
01:40 katsmeow-afk but the ice cream!
01:41 e_bed pours cats cream back into the icecreami
01:41 katsmeow-afk oh, thanks
01:41 rue_bed whirrRRRRRRRRRRRRRRRRRrrrrrrrrrrrrRRRRRRRRRRrrrrrrrrRRRRRRRrrrrrrrrrRRRRRRrrrr
01:41 tsmeow-afk purrrrrRRRRRrrrrrrrRRRRRrrrrrrrrRRRRRrrrrrrrr s along wit
01:43 katsmeow-afk got pipe from the tank (but not to the tank) (or attached to the tank) (but near to the tank) (where i'll put a cut-off valve) (tomorrow) into the hallway

11:34 furrywolf grrr... tomorrow isn't just supposed to rain, it's fucking thunderstorms!
11:34 furrywolf I haven't seen the sun in a fucking month!
11:37 furrywolf maybe longer
11:40 furrywolf wunderground says the last sun was 6/19, and it was only a brief clearing.
11:40 furrywolf last sunny day was 6/10, and even that wasn't that sunny.
11:40 furrywolf bleh.

20:07 tsmeow-afk quits loo
20:10 rue_shop did't want ot wait 10 days and get scooped
20:11 Tom_itx RUE_SHOP WANTS IT NOW!!
20:11 rue_shop buy them and sell them for $5 ea as reprap bearings
20:11 katsmeow-afk lotta those were BUY NOW
20:11 seravitae hm
20:11 e_shop runs his fingers thru his new box of bear
20:11 seravitae i need some bearing blocks
20:11 seravitae actually this is prob the best place to ask
20:12 seravitae i need to make basially a very small CNC table/gantry
20:12 seravitae where the HELL do you find miniture pillow blocks, bearings, etc, at a decent price?
20:12 Tom_itx or in #linuxcnc
20:12 Tom_itx mcmaster carr
20:12 Tom_itx sdp
20:12 katsmeow-afk i just found 100 small bearings for 30 cents each on ebay
20:12 rue_shop if I could only remember why I bought the bearings
20:13 Tom_itx http://www.sdp-si.com/
20:13 katsmeow-afk for that size, you can make your own pillow blocks
20:13 Tom_itx http://www.mcmaster.com/#
20:13 Tom_itx yeah or make your own
20:13 seravitae yeah i might have to make my own
20:14 katsmeow-afk rue makes them, i make them, Tom makes them, heck, drop them in some pipe and pot them in body filler if theload is light enough
20:14 seravitae can't hotlink to mcmaster, because they suck on many levels
20:16 seravitae hm, timing belt might be cheaper/easier for this job
20:16 tsmeow-afk grits her f
20:17 seravitae what about small nema motors?
20:18 Tom_itx stepper?
20:18 Tom_itx what size?
20:18 seravitae yeah
20:18 Tom_itx 17?
20:18 seravitae smaller
20:18 Tom_itx for what?
20:19 seravitae its not driving a large load
20:19 orlok i found a localo ebay shop that specialises in cupcake accessories
20:19 Tom_itx reprap?
20:19 orlok homebrew beer hardware
20:19 seravitae cupcake cnc on ebay
20:19 orlok and DIY CNC machine hardware
20:19 seravitae i bought from them heh
20:19 seravitae Tom_itx: I need to move a plastic tube over a 20cmx20cm space x-y
20:19 orlok seravitae: hah, really? cupcakes and CNC's? i only found them a few nights ago
20:19 Tom_itx get some from an old printer
20:20 orlok seravitae: ahh, you in vic too?
20:20 seravitae orlok: yeah i found cupcake cnc a while back. QLD here
20:20 seravitae Tom_itx: i want it to be reproducible
20:20 orlok those NEMA steppers are $$$
20:20 Tom_itx http://www.kelinginc.net/NEMA17Motor.html
20:20 orlok i like that aluminium framing they have though
20:20 seravitae i have a carton of nema 23's or nema17's here, but those are huge.
20:20 Tom_itx so use them if you have em
20:21 Tom_itx why buy more?
20:21 seravitae too big
20:22 seravitae NEMA 8 is 20mm x 20mm
20:22 seravitae that's probably doable
20:23 rue_shop katsmeow-afk, can you remember a datasheet with an op-amp thats set up for 4-20mA output?
20:25 katsmeow-afk set up for?
20:25 katsmeow-afk many will handle 20ma
20:26 katsmeow-afk TL081 , TL061, TL071
20:26 katsmeow-afk LM358 ?
20:29 katsmeow-afk oh,, you mean to drive a rs-232 directly?
20:29 katsmeow-afk no, not in my memory banks
20:29 katsmeow-afk easy enough to do with any opamp and any transistor tho
20:30 katsmeow-afk and one resistor
20:36 katsmeow-afk use a darlington, like a TIP102 or 2N6388, emitter thru 10ohm resistor to gnd, base to opamp output, opamp - to emitter-resistor junction, load tween collector and + , now toggle the opamp + from 40mv to 200mv to make the load see 4ma to 20ma
20:36 Tom_itx seravitae did you see the sugar reprap?
20:36 katsmeow-afk with a 15v supply for the opamp, you can use almost any mosfet in that same circuit
20:37 seravitae tom - yes
20:37 katsmeow-afk add protection circuits per your requirements
20:37 seravitae hm
20:37 seravitae qty 10 nema8 motors, $200
20:53 furrywolf you don't buy small pillow blocks. you machine a bit of aluminum to the shape you need, and press the bearing into it. heh.
20:53 furrywolf pillow blocks are stupidly expensive compared to bare bearings.
20:53 katsmeow-afk or plastics
20:54 katsmeow-afk some peple, like Triffid_Hunter, make them from wood
20:55 furrywolf wood makes a poor precision material.
20:55 katsmeow-afk we knows
20:55 katsmeow-afk but, you can sink a lot of bearings into a $2 2x4
20:56 tsmeow-afk has put ears on a piece of pipe, dolloped in some body filelr, and set the bearing int
20:57 katsmeow-afk and then again, i also made some really heavy ones for the overhead bridge crane
21:02 rue_shop off-the-head pinout for a 79L05?
21:03 furrywolf in, ground, out. or maybe it's out, ground, in.
21:03 furrywolf I don't remember if the 79s are backwards from the 78s.
21:05 rue_shop na, the L's are backwards, the 79's are just screwed up
21:12 furrywolf then it must be ground, in, out... they sort them by potential, or something like that.
21:16 rrywolf tickles spacekitteh rand
21:16 spacekitteh =^-^=
21:46 katsmeow-afk ok, permiate pressure recovery pump is pumping into pressure tank
21:47 Tom_itx is that good?
21:47 Tom_itx sounds good
21:47 katsmeow-afk yeas, and it sounds real scinetistic too :-)
21:49 rue_house ok, I made a 4-20mA regulated dc source and meter
21:49 katsmeow-afk means i can go to the tank (house sinks not plumbed into the ro system yet) and fill a couple gallon jugs as a pass by, instead of every 45 minutes by a timer
21:49 rue_house now we can find out more about why the auger at the poo processing plant isn't working
21:50 tsmeow-afk makes a joke she doesn't wanna type
21:50 katsmeow-afk but serioously, make sure you can turn it by hand (or pipe wrench) before you power it up locked rotor
21:51 katsmeow-afk never know what's in that auger tube, really
21:54 Tom_itx or may not want to find out
21:58 katsmeow-afk i knew huamsn who had nitemares
22:02 furrywolf I just wrote my boss a long email telling him to stop going to the mechanic he goes to.
22:04 furrywolf I took it in for new tires, dropped it off, and went to lunch. They noticed the left front wheel was loose. Duh, I know this, it's been clunking for a while now. Rather than talking to me, they called my boss up, and told him it needed a new wheel bearing. If they had called me, I would have told them to fuck off and just replace the tires like we told them to. This is why they don't call me.
22:05 furrywolf So, they convince him the wheel bearing is in dire condition and must be replaced immediately. They charge him $300 to do it. I go back to pick up the car, and they say it will be another couple hours, since they're doing the wheel bearing. grrrr....
22:05 furrywolf I drive it today, and it has the same clunk it's always had. Absolutely no change.
22:05 Tom_itx maybe he didn't want it to clunk for a while now, rather get it fixed
22:06 Tom_itx then he got screwed
22:06 katsmeow-afk i need a letter concerning the tadpole swimming in my #1 filter bowl, considering it's made it thru two filters at intake checkvalves, made it thru two pumps, and is now at 50psi
22:06 furrywolf In less than 30 seconds, I diagnose the problem as a bad strut.
22:06 Tom_itx and being a wheel bearing i doubt they used lube either
22:06 furrywolf meep! remove it and put it back in the stream before it's hurt.
22:07 katsmeow-afk i doubt they torqued the preload nut correctly too
22:07 furrywolf In order to change the wheel bearing, they had to remove the knuckle, which is bolted to the strut. And somehow during this whole process they never noticed there was nothing wrong with the bearing, and that all the free play was in the strut.
22:07 furrywolf I doubt they did too. Especially since it now makes bearing noise, which it didn't before.
22:08 tsmeow-afk rolls Tom's eyes, and then chases
22:08 furrywolf So, they charged my boss $300, didn't fix the problem they claimed they were fixing, and now it has more problems than before they worked on it.
22:08 furrywolf This is not the first time this has happened, either.
22:08 katsmeow-afk this is why i do my own car work
22:09 katsmeow-afk i still say the mechanic in Fla swapped my truck tranny for a worn out one off his wrecker
22:09 furrywolf If they'd called ME and told me they thought the looseness was a problem, I would have told them no, and did it myself - and fixed the proper part.
22:09 katsmeow-afk but i wasn't allowed to have a concrete slab to do the work myself
22:10 furrywolf once my boss took one of his other cars in, I think it was for an oil change... they told him it needed an alternator. A few hundred dollars later, they replaced it. He asked for the old one, since he hadn't noticed any problems. Took it to the local auto electric place, they bolted it to the test rig, tested perfectly. And he STILL didn't get the hind.
22:10 furrywolf hint
22:11 furrywolf They're not just crooks, they're incompetent crooks.
22:11 furrywolf They sold him a $300 wheel bearing job when they could have sold him a $1000 strut job if they'd properly identified the bad part...
22:12 Tom_itx so now they can sell both
22:12 katsmeow-afk yeas, 2nd time i was charged $250 for a alternator for the 280zx, i put a bigarsed Chrysler into it instead and homemade regulator, no more problems
22:13 furrywolf heh
22:13 furrywolf I put a 150A alternator in my jeep... need to replace it with a 250A one. :)
22:14 furrywolf the 150A one is a small-case one, and with the low belt ratio and low-rev engine, doesn't do much at idle... a 250A one will be a large-case one, and do better at idle.
22:15 katsmeow-afk 240vac motor at 15amps to spin a 250amp 14v alternator for a puter UPS ,, sounds crazy
22:16 furrywolf the alternator came with a teeny tiny pulley... I replaced it with the big wide pulley my jeep needs, and now it doesn't spin fast enough. heh.
22:16 furrywolf plus it was meant for an engine with a fast idle, not a 400rpm idle...
22:16 katsmeow-afk yeas, the chrysler was like 10 inches diameter, great at low rpm charging, which is when i usually got a dead batery: sitting at lites in town with headlites, heater/defrost blower/wipers/defrostheater all on high
22:17 furrywolf fortunately my jeep has two large batteries, so it can run with no charging for a while.
22:17 furrywolf I should drop a third back in. I stole it for my solar system.
22:17 katsmeow-afk i don't wanna cart lead around if i don't need to
22:17 furrywolf I do. :P
22:18 katsmeow-afk ok
22:18 furrywolf well, I don't necessarily want to cart lead around, but I want to be able to run lights, winch, etc for long periods.
22:19 katsmeow-afk i drove by the guy with wood today, had to goto post office to sign for a package they wouldn';t leave,, he burned all the rest of the firewood
22:19 furrywolf heh
22:20 katsmeow-afk we are in a drought and record heat wave, so he burns firewood, and this winter he will bitch about fuel costs
22:20 furrywolf the alternator I got is cool... dual 150A outputs. has two diode bridges, each with their own big stud.
22:20 furrywolf heh
22:20 furrywolf people are stupid. you know this.
22:20 katsmeow-afk yea
22:20 Tom_itx was he cold?
22:21 katsmeow-afk i think that alternator is simply isolating the batteries, it's not gonna do 150 on both ternimals at once
22:21 furrywolf no, it's not.
22:21 katsmeow-afk i doubt it
22:21 furrywolf I measured them at 143A combined, with the engine at ~2500rpm.
22:22 katsmeow-afk even that is hard on a batetry, most wil boil or swell at 140 amps, i know this :-/
22:22 furrywolf good thing it has (or will have when I stick it back in) three 115Ah batteries...
22:23 katsmeow-afk plus if the batetry is at 13.6v, it prolly will not take 140amps
22:23 furrywolf right now it only has two.
22:23 furrywolf yep
22:23 furrywolf it regulates around 14.1 or so.
22:23 tsmeow-afk
22:23 furrywolf I had to load the batteries down to take the current measurement.
22:23 tsmeow-afk
22:25 katsmeow-afk i think my public demo of a real strong ups will be short circuiting a extension cord, plug it into the ups, turn the ups on and video how long it takes for the extension cord to vaporise, while watching the volt/amp readings, and sine on a scope, too
22:26 furrywolf that sounds like your ups doesn't have proper output protection.
22:26 furrywolf my big inverter has a 20A breaker on the outlets and a 30A breaker on the hardwire terminals...
22:26 katsmeow-afk sure it does! at 150amps, it will shut off
22:26 furrywolf but if you're running that to a normal outlet, like you could plug an extension cord into, it needs a 20A breaker between the output and the outlet.
22:27 furrywolf otherwise the only acceptable wiring is, what, #4 copper?
22:27 katsmeow-afk course, i haven't built it yet, i gotta finish this bench psu so i can build modules and test them before i make them put out 120vac
22:27 katsmeow-afk "need smeede", let it smoke for the video
22:27 rrywolf likes proper circuit protection, not smoke.
22:28 katsmeow-afk the point is a mind worm that the person needing a powerful ups knows there is nothing they can plug into mine that will kill it
22:28 katsmeow-afk adjustable overcurrent is easy to do
22:29 furrywolf I've short-circuited my apc smart-ups a few times, hasn't let the smoke out.
22:29 katsmeow-afk a nameplate rating of 150amps continuous , that's what i wanna be selling
22:29 furrywolf it buzzes really loudly for a second or so, then shuts off a flashes the lights in a very, very angry "don't do that" fashion, different from a normal overload.
22:29 furrywolf s/a flashes/and flashes
22:30 katsmeow-afk start a window ac unit, start a fridge, run a cluster of 20 puters, etc
22:30 furrywolf I've been quite impressed by the apc smart-ups series... you'll need a good product to compare to them.
22:31 furrywolf I run my whole house, except the microwave, off a smart-ups 1000.
22:31 katsmeow-afk and you don't have a fridge
22:31 furrywolf fridge, computers, lights, mini lathe, champion juicer, etc.
22:31 katsmeow-afk or a ac unit
22:31 furrywolf I do have a fridge.
22:31 katsmeow-afk or a 3/4 hp water pump
22:31 furrywolf I have a fridge that draws enough that my chinese 600W inverter shuts down instantly.
22:32 katsmeow-afk ok, you have a fridge
22:32 furrywolf and yet my smart-ups starts it instantly.
22:32 furrywolf and I have a big submersible sump pump, and a harbor freight well/booster pump, although neither is routinly used.
22:33 katsmeow-afk is 19 inch rackmount a common format for those bigegr pricier upss?
22:33 katsmeow-afk or halfrack,, or what?
22:33 furrywolf the sump pump draws enough juice that the ups gets warm after a while, but hasn't melted yet.
22:33 furrywolf I think it's all standard width, but I'm not familiar with the rackmount stuff.
22:33 furrywolf I have only a 1000VA one.
22:33 orlok i think "big and pricy" is all relative.. but all of our UPS's are 4RU 19"
22:33 furrywolf 690W.
22:34 katsmeow-afk what is "standard" for upss tho? i dunno
22:34 orlok however we have one per rack, at other places, they have a few units the size of dishwashers
22:34 katsmeow-afk ah, see, orlok has massive puters on upss
22:34 orlok but they are for a whole large server room
22:34 tsmeow-afk
22:35 orlok then we have the things the size of a phone book just for desktops
22:35 furrywolf it starts the fridge effortlessly as long as the existing load is under 70%. above 70% the lights dim for a few seconds as the compressor spins up. I've never, not even once, had the fridge fail to start, even as the ups was right at its rated output. None of my chinese inverters will start the fridge, ever, under any circumstances.
22:35 katsmeow-afk i've seen some 1/6 rack 48v kw units, but they are like 2ft long
22:35 orlok we have systems with uptimes in the thousands of days, with no UPS in the rack
22:35 orlok katsmeow-afk> i've seen some 1/6 rack 48v kw units, but they are like 2ft long
22:35 orlok argh
22:36 orlok katsmeow-afk: out 19" rack UPS's are as deep as the rack
22:36 tsmeow-afk
22:36 orlok so about 48"
22:36 katsmeow-afk a 4ft deep rack??
22:36 furrywolf I took apart a 500kW UPS. it's where I got my stack of 400A, 600V darlingtons. :)
22:36 orlok yeah
22:36 katsmeow-afk i thought google's servers were big, they are 24 long
22:37 furrywolf it came in three pieces, each large cabinets about 7ft high.
22:37 orlok furrywolf: can you remember the brand?
22:37 furrywolf nope
22:37 furrywolf this was a while ago
22:38 furrywolf it had been scrapped, scrapyard said it was from some government building
22:38 katsmeow-afk so you see, a 15kw ups isn't such a huge ups
22:38 furrywolf one of the employees kept the huge bank of l16s for his solar system. wouldn't give me any. bleh.
22:38 katsmeow-afk big battery
22:39 katsmeow-afk so you didn't get those NiFe's?
22:39 furrywolf I haven't called the guy yet. I'm debating it...
22:39 furrywolf I'll probably see if I can get him to offer some gaurantee, either of their working, or at least of the steel-cased ones not being rusted through.
22:39 katsmeow-afk potassium-nickle-iron : KNiFe
22:40 katsmeow-afk working? hell, i'd be afraid to power that mess up
22:40 katsmeow-afk i got a oscope once, in bad shape, took it outside to plug it in!
22:41 furrywolf working after a cleaning and an electrolyte change.
22:41 katsmeow-afk be very delicate when wringing off, err, unbolting those bonding straps
22:42 furrywolf my plan was to soak them in penetrating lube for a day first...
22:42 katsmeow-afk might contaminate the cells
22:42 furrywolf given as some people recommend using float oil in them, I'm not too worried.
22:42 katsmeow-afk afk to see how badly the ro tank isl eaking, if it has pressure
22:47 katsmeow-afk very very small leak at the ro water outlet on the ro filter, and the guest fitting is epoxied into the 1/8 threaded port on the filter body
22:47 katsmeow-afk tank has 16lbs pressure
22:48 katsmeow-afk been running an hour
22:51 furrywolf initial pressure?
22:52 katsmeow-afk the tank? zero
22:52 katsmeow-afk no water
22:52 katsmeow-afk new tank, bladder, unknown pressure in bladder
22:52 katsmeow-afk says it's a 3.5 gal tank
22:53 katsmeow-afk dirty water is 40-50psi
22:53 katsmeow-afk i dunno how the tadpole takes that pressure cycling
22:53 furrywolf the bladder is usually precharged to 8-10 psi or so
22:54 furrywolf rescue the tadpole! :(
22:55 katsmeow-afk i will, but would rather not atm, while i am seeing how the pressure tank and pump works
22:56 furrywolf :
22:56 furrywolf (
22:56 katsmeow-afk i dunno how it made it thru the pump to get up the mountain, and then thrut he bigegr pump into the house pipes
22:58 furrywolf perhaps a frog laid eggs in your pond?
22:58 furrywolf (pool)
22:59 furrywolf the shurflos have an internal screen (or, at least, the ones I've taken apart did), so I don't know how it could have gone through one, unless it came up a while ago when you had the bigger pump.
23:00 katsmeow-afk i had geotexttile over that pump intake also
23:00 katsmeow-afk oh, the pool-tank is full of tadpoles now, and i saw some new eggs today. No mosquitoes tho :-)
23:02 furrywolf needs an input screen. heh.
23:02 katsmeow-afk since i told you twise already i have screens, not gonna do it again
23:03 furrywolf oh, I thought you meant on the pump in the creek, not the intake in the pool.
23:14 katsmeow-afk hmm, i accidently traded a couple handfulls of salvaged scope parts for some other scope parts which i'd rather have
23:14 furrywolf that's a good thing, right?
23:14 katsmeow-afk i also accidently got $150 of working scope plugins for s&h
23:15 katsmeow-afk oh yeas
23:15 katsmeow-afk gotta box them up, tmorrow, since it's now 11pm and i don't want my brain to shut off in the middle of doing that
23:17 katsmeow-afk 10 microvolt/division differential scope amplifier and 500picosec/division timebase, both demonstrated working
23:17 furrywolf heh
23:17 furrywolf I rarely accidentally get stuff. heh.
23:18 katsmeow-afk they been sitting there not selling, grouped with something else, so i sent the seller a lowball offer, he accepted in minutes
23:19 furrywolf heh
23:19 furrywolf I made a lowball offer on the fried inverters, and he told me to get lost.
23:20 furrywolf it's still for sale. somehow no one has decided to spend $450+shipping on someone else's repair project that comes with a bunch of bits, including the fried transistors, loose in a bottle.
23:21 katsmeow-afk http://www.barrytech.com/tektronix/tek7000/tek7b92.html http://www.barrytech.com/tektronix/tek7000/tek7a22.html in a not-free-but-bargain-working http://www.barrytech.com/tektronix/tek7000/tekr7903.html
23:23 katsmeow-afk one of the items i got in trade on the otehr deal is a working crt for that scope number (i have a possibly dead one), and a http://www.barrytech.com/tektronix/tek7000/tek7d01-df2.html
23:29 rrywolf sorts through a box of assorted tools from a yard
23:30 rue_house furrywolf, point out their still up for sale, give him a lower offer
23:31 rue_house and ask him how much its cost him for the space their sitting in since he got them
23:31 katsmeow-afk yeas, and don't do like i did with offers, seems the sellers prefer your subsequent offers go UP, not DOWN
23:31 rue_house and how much stuff he could have sold, but didn't, cause he disn't have room for
23:36 katsmeow-afk my brain is already off :-/
23:41 katsmeow-afk woo, got a $70 refund too
23:41 furrywolf why
23:41 furrywolf ?
23:41 katsmeow-afk not as describes
23:42 katsmeow-afk seems the seller company aslo has a policy that they cannot say what they said about the item, but they said it, and the device did not perform to the description
23:43 katsmeow-afk so while they first refused to consider, i pointed out the relavant text, and they were like,, don't know how that happened, but it did, we owe you, what do you want?
23:44 katsmeow-afk i've blown ,, er, spent alot of money with them before, and i suggested i pay as much for their dead device as the working one i got from someone else, and they aggreed
23:45 katsmeow-afk "hmm, i can buy this working one,, or for $70 more, i can buy this dead one!
23:45 katsmeow-afk so they refunded, no questions
23:47 katsmeow-afk the trade deal worked on the same premise: i am not going to spend anything on 1/3 of the parts from a dead device, if i can buy the entire device working for the same money
23:50 katsmeow-afk it was a lil like getting a http://www.barrytech.com/tektronix/tek5000/tek5110.html for just paying s&h on it, because the guy selling it *with* plugins didn't know what the plugins were, so i bought the plugins for a song and told him to keep the scope,, he didn't want it either, and i tried giving it away in here for the s&h costs, finaly i accpted it just so it wouldn't be landfilled
23:52 anannie hi katsmeow-afk
23:56 katsmeow-afk hi anannie
