00:20 mbass-afk ponders dynamic battery shifting and body leaning to take very high speed turns in Walmart, assisted by overhead cameras providing Total Situational Aware
00:27 rue_house what are you up to kat?
00:27 rue_house this sounds like odd plans
00:28 dumbass-afk well, i found i can get smaller motors in lower volts that also make more torque,, but they spin at 1/4 the rpm
00:28 dumbass-afk but if i direct drive the tire, it's more rpm than i need anyhow
00:28 rue_house ah
00:29 rue_house the only problem I have with thains is derailment, but I keep using bike chains
00:29 dumbass-afk so if i gear-down so the tire has the same ground push as the motor has inch-pounds of torque, i *still* have more rpm that i can use
00:30 dumbass-afk use more idlers, use auto-chain tensioners,, chains been in use forever
00:31 dumbass-afk and use a drive motor on every wheel
00:35 dumbass-afk so if i direct drive, run the 12v motor at ~3v with pwm, use rpm feedback and torque sensing, i still have more rpm than i need, so why not burn rubber in Walmart?
00:35 dumbass-afk i mean "direct drive" is one chain sprocket-to-sprocket
00:36 dumbass-afk at a measely 10 inch lbs per motor, 4wd will gimme 40lbs of towbar pull
00:39 dumbass-afk with a 2" drive sprocket and 8" on the tire, 4 revs of the motor gives me one turn of the tire, a 10" tire is 31" around, so 4 motor turns is 31 inches robot travel, i need only 2043 motor rpm to hit 60mph
00:39 dumbass-afk i dunno the motors will do 2000 rpm tho, but it's a thought

04:45 dumbass-afk Report: Britain hacked Belgian telecom operator
04:45 dumbass-afk A news magazine is citing documents leaked by Edward Snowden as saying that Britain's spy services were behind a sophisticated cyber-espionage scheme targeting Belgium's main phone operator.
16:17 mbass-afk still says it's a good idea to buy a couple acres and plant solar on it each month for 10 yrs ,, because if you plant $200 per mo on it, at the end of 10 yrs you'll have $24,000 on it, and it will generate $1000 per month (@ $0.05/
16:19 mbass-afk thinks if you pause the planting for 2 yrs, it will pay for itself, then you can double it's size in 2.5 yrs at $1000/mo , raking in $2000/mo, then double again in *one* year and rake in $400
16:19 mbass-afk thinks this does not include weather forec
16:20 dumbass-afk or glass or the sun-tracking systems, or getting paid for your labor
16:21 dumbass-afk and 120kw per acre is pretty dense, you'll need more acres
16:22 dumbass-afk and my figures are for 6 hrs of sun per day, your sun may vary
16:23 dumbass-afk iirc, in Oz, some people locked in getting way more than 5 cents kwh a few yrs back
16:24 dumbass-afk and in some usa states, you get paid what the powerco charges you
16:26 dumbass-afk oh, my numbers were for price of *cells* at $200/kw, not *panels*
16:32 rue_house ooo I like the numbers
16:33 rue_house I'd like to find ways to make every square meter of my place make a bit of money on its own
16:33 dumbass-afk if you had my luck, the neighbors wold make every inch cost you money
16:34 dumbass-afk my plan was this place make me 2x as much money as i have now
16:34 rue_house roof on the shop is more than 480 square feet
16:34 dumbass-afk instead, i have spent 2x as much
16:34 rue_house I just found out I had the UPS battery array on a 48V charger
16:34 rue_house for god-only-know how many monthe
16:34 dumbass-afk if you put an entire 1kw in one panel, you need a 10ft x 10ft panel, and only 3 steering motors
16:35 rue_house if I use mechanical linkages, I only need one steering motor
16:36 dumbass-afk the gotcha with tracking arrays, as the tilt up they shade the ones behind, with one huge array they all face the sun with no shade
16:36 rue_house ok, I have to go make cages for the hedge trees, the deer been at them
16:36 dumbass-afk cage = electrified chicken wire
16:37 dumbass-afk unless the bears get tangled in it
16:37 dumbass-afk i still say : put a water cannon on the mowerbot
16:38 dumbass-afk even a powerful enough sprinkler system should work, add bear pee to it when sprinkling the deer, they'll leave
16:39 dumbass-afk 2 or 3 small mowerbot-sized with 2liter water cannon bottles (auto refilling software) should be plenty to annoy the deer into going over to the neighors
16:40 dumbass-afk use them to water the strawberries if there's no deer
16:42 dumbass-afk i keep having issues with the weight and fragility of glass
16:57 dumbass-afk hmm,,, L shaped water pipe, fill the horizontal portion with water, the vertical portion with propane and air, topped with a spark plug, it that wheeled itself up you during lunch and pounded you in the face with 10 ounces of water, wouldn't you be interrupted?
16:59 rue_house the hand tractor bent the pins ont eh casters, I have to go get new ones, and cat food, and pipe nipples
16:59 rue_house its just a problem with casual browsing deer, they aren't persitant, I'v watched them, they are pretty lazy eaters
17:00 rue_house everything in comfortable mouth height is a target
17:00 dumbass-afk "hand tractor" ?
17:02 rue_house http://eds.dyndns.org/~ircjunk/images/dscn0826_handtractor.jpg
17:02 rue_house I painted it since
17:02 rue_house most of it wore off, looks the same
17:02 dumbass-afk you humans with your exelent webpages <sigh>
17:03 dumbass-afk you NEED 1" dia spindles
17:03 dumbass-afk as you may have noticed, 1/2 inch is WAY too small, they bend
17:03 dumbass-afk 1" pipe is prolly too bendy even
17:04 rue_house its collared down to even smaller
17:04 rue_house I'm gonna get some grade 8 that just fits
17:04 dumbass-afk grab anotehr dead riding mower, use it's rear axkles as spingles, you should be good for 500 lbs then
17:04 dumbass-afk spindles
18:03 mbass-afk hmms and ponders using pvc glue to stick poly wrap film to s
18:17 dumbass-afk Sea Water Cooling System for Downtown Vancouver Proposes to use a sea water cooling system to replace air conditioners used by office buildings. ... Two parallel 16" diameter polyethylene lines siphon seawater.
18:25 rue_shop2 $13 for 2 grade 8 bolts
18:25 rue_shop2 :)
18:25 rue_shop2 10"
18:25 rue_shop2 .75"
18:26 rue_shop2 3/4"
18:26 rue_shop2 the old ones are mild steel, 1/2"
18:26 rue_shop2 oh they were .625
18:27 rue_shop2 hmm 5/8"
18:27 dumbass-afk plus, it's like if you take 1/16 off bolts in the small sizes, you lose 1/2 the strength
18:28 dumbass-afk gotta figure the point of leverage to bend it is whatever the tire diameter is
18:28 rue_shop2 it took over 4 years for the 5/8" mild steel to bend!
18:29 rue_shop2 but I wonder how much strength the grade 8 loses after welding
18:29 dumbass-afk ok
18:30 rue_shop2 I know your right, part of the reason I'm going this way is because the bushings I have would be REALLY hard to change
18:30 dumbass-afk so don't weld the bolt, weld the 3" long coupling nut the bold screws into
18:31 dumbass-afk once you weld the nut, it will have changed shape so much the bolt will bind and never unscrew by itself
18:32 dumbass-afk it has always puzzeled me: for 5 days in a row the events in the world are so important for me to know, the tv shows 90 minutes/day of it, then the next two days it shows 15 minutes/day of it
18:39 dumbass-afk i think i need some cheap 1/4 inch solid plastic flexable rod, poly is fine
18:39 dumbass-afk 100's of feet
19:07 dumbass-afk ebay breaks after http://www.ebay.com/sch/i.html?_odkw=polyethylene+-teeth+-tape+-roller+-rollers+-printed+-sign+-signs+-hole+-plug+-plugs+-sheet+-sheets+-disposable+-protectors+-mailers+-shoes+-covers+-sliders+-protector+-mailer+-shoe+-cover+-slider+-cap+-caps+-bumper+-fabric+-shirt+-dropper+-bag+-bags+-disc+-discs+-foam+-clip+-clips+-pipe+-tube+-nipple
19:11 mbass-afk may find herself in the position of melting down plastic bottles to make stuff
20:10 mbass-afk ponders putting an avr inside the solar panels to operat
20:15 dumbass-afk rue, i am making a steel boat, steel rusts in ocean walt, paint is pretty darned temporary, and pricey
20:15 dumbass-afk if i can apply something better for cheaper, why not?
20:15 dumbass-afk there are companies making shrink wrap for pipes
20:21 dumbass-afk $28 ; free s&h ; 100Pcs IRFZ44N IRFZ44 N-Channel 49A 55V Transistor MOSFET ; 141053615844
20:23 dumbass-afk 0.2v drop @ 8amp @ 10vgs
20:24 dumbass-afk 28 cents each
20:24 dumbass-afk dayam
20:24 dumbass-afk why would anyone use a diode as a rectifier any more?
20:27 dumbass-afk so if i put an avr and 5 fets in a panel of 5x6 cells, with 2) pwr out, 2) signal/pwr out , then i be good ?
20:28 dumbass-afk ok, 8 fets
20:28 dumbass-afk 12 fets, but not one more!
20:29 dumbass-afk to switch out and bypass each row of 6 cells = 10 fets, switch out and bypass the entire panel = 2 fets
20:30 dumbass-afk $3.36 + avr and misc to make the panel immune to shadows and shorts and reverse currents, as well as log it's data in the avr and out on a serial line
20:31 rue_house aliexpress for IR2101
20:32 dumbass-afk hmm ?
20:32 dumbass-afk fet driver?
20:33 dumbass-afk bipolar driver?
20:34 dumbass-afk makes one wonder why you need a low side driver
20:37 dumbass-afk 50 cents each?
20:38 rue_shop2 its cheaper to get one that can do both than to jsut get a high side driver
20:38 rue_shop2 (!?!?!)
20:39 rue_shop2 but it will take care of timing for you too
20:39 dumbass-afk then why does it have separate LO and a HI input?
20:43 Tom_itx i heard a MB cap pop earlier. i wonder how long before it blows up
20:44 dumbass-afk if it blows, i wonder how long before you get a scrambled disk drive
20:45 Tom_itx i'm pulling it out
20:45 Tom_itx gonna try to replace em
20:45 Tom_itx the ones i got for it are a bit too fat
20:45 dumbass-afk didn't you do that before too?
20:45 Tom_itx didn't replace em all on this board
20:45 dumbass-afk oh
20:45 Tom_itx it was the other identical one
20:45 dumbass-afk oh
20:46 dumbass-afk it still ok, i presume
20:46 Tom_itx the other one never gets used
20:46 dumbass-afk oh, a spare,, then just swap em
20:46 Tom_itx different cpu
20:46 Tom_itx all that windows... you don't belong here crap
20:46 dumbass-afk oh
20:48 mbass-afk is not looking forwards to the day when she wants external world io to a windows puter a
20:48 Tom_itx at least i got some higher temp tips to manage the RoHS solder this time
20:49 mbass-afk weeps for the
20:49 dumbass-afk don't overheat the caps either
20:51 dumbass-afk there was a pile of 27,000u 35v caps at the recycler, someone had clipped the wires off right at the cap body, no saving them without a way to weld new wires onto them
20:52 rue_shop2 wow
20:52 rue_shop2 maybe it was one of those, we have to throw these out new, so we must make sure nobody else can use them
20:53 dumbass-afk no, prolly the leads are steel, they wanted to separate the aluminum off them
20:54 mbass-afk hangs a electrolytic on a magnet by it's l;egs to demonst
20:55 dumbass-afk yeas, you'd think they'd be copper
20:56 Tom_itx i wonder if i should remove the backup battery before soldering
20:56 dumbass-afk since the way you did it last time worked ok, i'd do it the same way
20:57 mbass-afk makes up some salt water of unknown , but saturated, concentration, to test a method of preventing corro
20:57 dumbass-afk bbiaf, hate to get salt on everything down here
20:57 Tom_itx don't remember what i did
21:38 dumbass-afk hence photos, Tom
21:40 dumbass-afk ok, some un/protected steel and alum in salt water, clamped together and connected with jumper clip ; was making 0.230v before connecting
21:42 mbass-afk ponders some really thin sheet steel, really thin muslin cloth, aluminum foil, and a layer of waxed paper, coiled up in a tube, pour in salt water, to make electri
21:42 dumbass-afk prolly been done before tho
21:52 rue_shop2 Lolina8088, ... poke
21:52 Lolina8088 oooh... again?
21:52 dumbass-afk syntax error: poke addr,data
21:53 rue_shop2 :)
21:53 rue_shop2 Lolina8088, hows the night been so far?
21:57 Tom_itx ok that wasn't so bad
21:58 Tom_itx worked alot better with the hotter tip
22:03 Lolina8088 jamming with Roland and Susy...
22:03 Lolina8088 First time in years
22:03 Lolina8088 my bass was dusy. :(
22:12 dumbass-afk maybe there isn't enough salt, the alum is bubbling a barely noticeable amount, the steel is unchanged
22:32 Lolina8088 rue_shop2, you getting lots done?
22:37 rue_house yes
22:37 rue_house just modifying the last of the motor drivers for buddy
22:37 rue_house Lolina8088, oh you were playing!?
22:38 rue_house dam, I have to be in on that sometime
22:38 dumbass-afk hmm?
22:47 rue_house damn you deleted your converter image
22:50 Lolina8088 yup...
22:51 Lolina8088 it's great... but my hand is cramping up
22:54 dumbass-afk what?
22:55 mbass-afk goes back upstairs to the ban
22:55 Tom_itx tall bandsaw
23:14 rue_shop2 Lolina8088, "push the strings down jsut as much as you need to"
23:14 rue_shop2 :)
23:14 dumbass-afk i doubled the salt in the Aqueous Anti-Corrosion Salt Test Chamber (peanut butter jar)
23:14 rue_shop2 I bet you dont know if I absorb half the things you tell me
23:15 rue_shop2 okk I have modified and reinstalled all the motor drivers on buddyIII
23:15 rue_shop2 next I need to mount all the overload boards
23:15 dumbass-afk and the water cannon?
23:15 rue_shop2 which I dont have mounts designed for
23:15 rue_shop2 dumbass-afk, I didn't design its load capacity for a water canon...
23:16 dumbass-afk neither did Apple, there's no app for that :-|
23:16 rue_shop2 I cant find a time travel app either
23:16 rue_shop2 oh what was the other one that suprised me...
23:17 dumbass-afk i don't have room on my to-do for it either, sorry
23:17 rue_shop2 oh wifi signal strength meter
23:17 rue_shop2 a proper one, better than 1 to 5 bars
23:17 Lolina8088 hey... come over later
23:17 dumbass-afk what was the phone that always reported 5 bars even if there was no signal?
23:18 rue_shop2 Lolina8088, its 9am, "later"?
23:18 Lolina8088 nope
23:20 rue_shop2 ARG, 6 boards, 4 corners, I have to make __24__!? OF THESE!?!?! ARG.
23:21 e_shop2 looks at the little peice of m
23:21 dumbass-afk i TOLD you to use the robot arm!!
23:21 rue_shop2 hmm I suppose I can have the cnc machine drill them
23:21 dumbass-afk you better
23:21 e_shop2 looks at the heap of stuff on the cnc mac
23:21 dumbass-afk tell the robot arm to clean off the cc
23:23 rue_shop2 does a usb power adapter go in power adapters, or usb junk?
23:23 dumbass-afk yeas
23:23 rue_shop2 does a set of alligator clips to a female cig lighter socket go in power adapters or connectors?
23:24 dumbass-afk adapters
23:24 dumbass-afk clips go into "connectors", sockets go into "connectors", but not clips soldered to a connector
23:26 rue_shop2 haha! I turned the power on and there were no large blue flashes!
23:26 rue_shop2 hmm I bought too many rulers, I need a longer scerw to hang them on
23:28 rue_shop2 ok iirc, I write a basic program to write the cnc file that I run
23:28 rue_shop2 hmm I'm stepping on a gold plated RCA connector... where did that come from...
23:29 rue_shop2 hmm where is the cnc chuck key
23:30 mbass-afk measures and maths th
23:31 dumbass-afk well, that's gonna need a 4-40
23:36 dumbass-afk AAAAAAAAAAAAR$GGGGGGGGGGGGGG
23:36 dumbass-afk my hole drill template is 6-32 !!!
23:38 rue_shop2 I'd bang you out a new one, but I suspect you dont want to wait for it to get there
23:38 rue_shop2 so make a collet
23:38 rue_shop2 if you ignored everyone and finished the drill rig...
23:39 rue_shop2 ooo cat is locked in and she is ANNOYED
23:51 e_shop2 watches the cnc poke the air in the test
