00:05 any67064803 what was the fix?
01:43 rue_house one of the motor drivers had been built with a 32V flyback diode, the system runs lead-acid at 48V
01:43 rue_house so it shorted,
01:44 any67064803 o
01:44 rue_house when I upgraded the fuses, just a little much, one of the transistors exploded
01:44 y67064803 would fuse each motor/controller, so if one more shorts, the robot can still hobble home on 5
01:44 rue_house I found a 60V diode, put that in a completely new motor driver, and put a LC filter on the motor supply
01:45 rue_house the two drive motors are individually fused
01:45 any67064803 k
01:45 any67064803 http://img.gawkerassets.com/img/18w7bi2fqnkj4jpg/ku-bigpic.jpg <<== NOT Tiggr
01:45 rue_house but on extended testing, the controller will still reboot if there are instantanious reverses under some conditions
01:45 rue_house so I'm really still working on it
01:46 any67064803 what about filtering that 48-12 convertor line?
01:46 rue_house yup
01:46 rue_house thats next
01:46 any67064803 k
01:46 rue_house and I have a nice big 82000uF cap for the logic power too
01:47 any67064803 you don't need 82 amps
02:10 rue_bed everyone needs 82 amps
02:10 rue_bed kat, can you think of a test to know if the world is actually real?
02:12 any67064803 yeas, but you may not survive, and you won't be able to tell anyone about it
02:15 any67064803 speaking of robots, are these real humans? ==>> http://www.latimes.com/media/photo/2013-10/77965879.jpg
09:12 rue_house go up to them and say, "my dog is brown, what colour is my dog?"
09:23 katsmeow-afk "don't know, but its name is brown"
09:23 rue_house :)
09:23 rue_house shoot to kill shoot to kill shoot to kill
09:25 katsmeow-afk so do i wanna get that 8hp 72vdc motor?
09:25 rue_house for the tractor?
09:26 tsmeow-afk sh
09:26 katsmeow-afk 72vdc@100amps is alot of power
09:26 katsmeow-afk i am sure the motor would handle a minute at 200amps, or 15sec at 300amps
09:27 rue_house get a motor thats going to last longer than a minute :)
09:27 katsmeow-afk on the other paw, no one could sell a car in the usa with a peak hp of 24hp
09:27 rue_house 24!?
09:27 katsmeow-afk an rms of 20 peak of 200, yeas
09:27 katsmeow-afk 3x8=24
09:28 katsmeow-afk 8hp@100amps, 24hp@300amps
09:28 rue_house if parked by the edge of the parking lot, one could probably sell a car that only lasted a minute too
09:29 rue_house "but it died just 50 feet down the road!!" "sorry, all sales are final"
09:29 katsmeow-afk but it was just *coasting* down the hill, i never touched the gas pedal!
09:30 rue_house er, that would be canadian, for usa remove "sorry" and put "sir" or "mam" on the end
09:30 rue_house heh
09:32 tsmeow-afk drops a bag of skittles and gets the pee scared outa her by the wierd n
09:32 rue_house run little skittles run!
09:33 tsmeow-afk puts her hair down and chases one of
09:33 katsmeow-afk skittles skittering across the floor
09:35 katsmeow-afk the feeling of hair standing on end is enough to make one's hair stand on end,, it's a natural feedback loop
09:37 katsmeow-afk not enough hp : https://dl.dropboxusercontent.com/u/183289187/seasteading/ramform-rubber-boat-broad-stern.jpg
09:52 katsmeow-afk hmm,, there's apps, and app-roval

13:09 katsmeow-afk a shill bidder, he's bid only on this one seller the last 30 bids
13:12 katsmeow-afk "we call it shrimp ramen, because we hire men off the shrimp boat to chop and hang the ramen, so you can just sense the... aroma of the shrimp when ramen is dry"
13:14 katsmeow-afk "this is chicken ramen, we pour old fat drippings in here day before they go bad, chop and hang that night"
13:14 katsmeow-afk "waste *nothing*"
13:17 katsmeow-afk "you smell like old manure, you want to chop and hang mushroom ramen?"
13:19 katsmeow-afk "this is pork ramen, we not know what is in it, old man come in back door, we hear spashes, he whisper over barrel: 'poooorrrrk' "
13:23 katsmeow-afk the ram went for $50, to someone not me
13:24 katsmeow-afk 225megabytes of 15ns static ram
13:24 katsmeow-afk bbl
18:33 katsmeow-afk i put my site back up, the ftp says it's over a gigabyte, but i know some big pics got pushed up
18:36 katsmeow-afk Washington U. Study Details Norture�s Effect on Adolescent Brains
18:36 katsmeow-afk October 29, 2013 7:23 AM
18:38 katsmeow-afk local tv said "an arrest has been made in the Sunday shooting, but not the shatterday nuding (saturday shooting)"
18:50 katsmeow-afk Nevertheless, Navigant Research says the market for small generator sets is growing, and projects small diesel generators will be a $41 billion global market, and small natural gas generators a $10 billion market, by 2018.
18:53 rue_house is it 15ns 8M sram?
18:54 katsmeow-afk no
18:55 katsmeow-afk but i have some of those too
18:55 katsmeow-afk oo, no, dram
18:55 katsmeow-afk however, a dual-port dram with each port 180 degreess opposite in refresh may look like an sram
18:58 rue_house boiler tank is at 42c
18:59 katsmeow-afk one data miner i started in March(?) this yr has only 2,252 hours of running till it's done :-)
18:59 katsmeow-afk 93 days
18:59 rue_house I dont think a 2G usb key is a good deal for $5
18:59 katsmeow-afk what makes it a key?
19:00 katsmeow-afk 2Gb sounds like an enourmous encrypted key to unlock a puter access
19:00 rue_house when you plug it in, windows open
19:01 katsmeow-afk 93 days is the beginning of Feb 2014 :-/
19:03 katsmeow-afk well, i got 14ft alum boat trailer frame cut and laid out in the driveway
19:11 rue_house http://www.ebay.com/itm/10pcs-DC-DC-Converter-Isolated-Power-Module-5V-DC-SIP/140744574787
19:11 rue_house hahaha
19:11 rue_house ok wait
19:11 rue_house wait
19:11 rue_house so, you put 4.5 to 5.5V in
19:11 rue_house yo get 5V out
19:11 rue_house min current draw is 20mA (as in you have to..) and max is 200mA
19:11 rue_house 70% efficient
19:12 katsmeow-afk ouch
19:12 katsmeow-afk it must be a double conversion
19:12 rue_house aaah, but its got 1kV isolation...
19:12 katsmeow-afk ok, it is
19:12 rue_house between what appear to be 100thou pins
19:13 katsmeow-afk on a 14ft boat, you put an engine high up in the air on it like this : http://www.ebay.com/itm/2010-14ft-Carolina-Skiff-w-25hp-Evinrude-E-tec-Trailer-/171157754785 , it will get real tippy
19:13 katsmeow-afk if you put the engine down real low, the transom is so cut down you have no freeboard and then you end up swimming anyhow
19:14 katsmeow-afk so i wanna put a large 1-clyinder or medium 2 cylinder midships under a console
19:14 e_house
19:15 e_house points at a motorbike engine out in kats
19:15 katsmeow-afk raise the transome back up where it belong, and thicken the sides, lose the taper in the sides, and add styrofoam blocks
19:15 katsmeow-afk that Yamaha engine has been dead since the day after the neighbor got dogs
19:16 rue_house oh, but... its still between the box and spokes?
19:16 rue_house is that wy the tires went flat?
19:16 katsmeow-afk what pic are you looking at?
19:16 rue_house your yard cart
19:17 katsmeow-afk the 3-wheeler?
19:17 e_house
19:17 katsmeow-afk no, i cut the yamaha parts off the dumpbed-rearaxle, to put different running gear on it
19:17 rue_house unless you put bigger tires on it, its no good for water anyhow
19:18 rue_house 5k, gee, I think you can almost get those for free up here
19:18 katsmeow-afk besides, it really needed power brakes
19:19 katsmeow-afk the yamaha engine was not reliable, and i'd have needed to add electric boost to it if i'd kept it
19:19 rue_house I was thinking more on how to make a doubleacting steam engine from common parts
19:20 tsmeow-afk
19:20 rue_house the engine would usually be cranking but occasionally give a little back into the system with a kick or two?
19:21 katsmeow-afk no, it would just die, especially when cold
19:21 rue_house half for full stroke?
19:22 katsmeow-afk the Yamaha? 4-cycle , no oil in gas
19:22 katsmeow-afk had a pull starter cord on it, i converted it to electric start
19:25 katsmeow-afk the Yamaha 3-wheeler was so dangerous, badly designed, the usa congress made it illegal, but it's incredibly stable if you bolt a VW transaxle like i did
19:27 katsmeow-afk i moved a lotta tons of dirt in that thing
19:27 katsmeow-afk and rocks, one rock was 6ftx4ft, teardrop shaped, 6" thick in the middle, made a beautiful stepping stone where i moved it to
19:33 katsmeow-afk put the yamaha tranny in low, the vw transaxle in low, the thing ran 1/2 mph with the throttle wide open
19:34 katsmeow-afk 4 reverse gears, the oem yamaha had no reverse
19:54 katsmeow-afk ...
22:34 rue_house Lola8088, there you are
