01:35 AM rue_mohr: tom ^^
02:01 AM rue_mohr: hah Tom_L you must be jellous

08:16 PM rue_mohr: mhm
10:06 PM Tom_itx is now known as Tom_L
10:32 PM zhanx: rue_mohr, think i could get 8 gpm with a stepper as a pump motor?
10:33 PM zhanx: asking as I have a few extra
10:35 PM rue_mohr: at 0 psi?
10:35 PM zhanx: 14 psi max for head lift
10:35 PM rue_mohr: no
10:36 PM rue_mohr: power dude
10:36 PM zhanx: k
10:36 PM zhanx: not like i don't have 90amps at 12v if needed
10:36 PM rue_mohr: motor voltage*motor current *0.8 (I'm being nice) -> pump power * 0.6 ?
10:37 PM rue_mohr: I cant think z
10:37 PM zhanx: k, I will pick up a pump then, it will be cheaper
10:37 PM rue_mohr: I'm getting uneasy, I dont think I usually cant think for this long
10:38 PM zhanx: this is for washing gear
10:38 PM rue_mohr: I'm gonna use a 1/12Hp motor
10:38 PM rue_mohr: induction
10:38 PM zhanx: so a pump from harbor freight is fine
10:38 PM rue_mohr: like, full induction, no cap
10:39 PM rue_mohr: carefull
10:39 PM rue_mohr: parts washer pumps cannot take varasol
10:39 PM rue_mohr: their for water based cleaners only
10:39 PM zhanx: oxiclean
10:39 PM rue_mohr: do you know any water based cleaners that actaully work?
10:39 PM rue_mohr: I'm just making mine varasol
10:39 PM rue_mohr: I made a pump, its not that great tho
10:40 PM zhanx: oxiclean works good not great
10:40 PM zhanx: and its something you can put your hand in
10:40 PM rue_mohr: found a pump I might bodge
10:40 PM rue_mohr: has anyone you have ever known or known of died from having made contact with varasol?
10:40 PM rue_mohr: (liver damage I presume)
10:41 PM zhanx: either way I need 8 gpm min
10:41 PM zhanx: not that i know of
10:41 PM zhanx: but i know oxiclean is safe
10:41 PM rue_mohr: I know varasol washes away grease
10:42 PM zhanx: I use a mix 2 part cleaning
10:42 PM rue_mohr: have any dxf files?
10:43 PM rue_mohr: been working on this cam program
10:43 PM zhanx: no, its a bin with a pump
10:43 PM zhanx: oh
10:43 PM zhanx: no
10:43 PM rue_mohr: for the enxt step, I need to take a struct for a cnc operation, and specify a list of objects to apply to it
10:44 PM rue_mohr: a solution is not comming up
10:44 PM rue_mohr: I have an array of all the objects
10:44 PM rue_mohr: but I was planning on supporting deleting some of them
10:45 PM rue_mohr: which screws with single-copy lists
10:45 PM rue_mohr: maybe if I think of it like a database
10:45 PM zhanx: bubble sort the list?
10:45 PM rue_mohr: the order of the list doesn't matter
10:46 PM zhanx: sorry meant the cut order
10:46 PM rue_mohr: I need the cnc operation ("drill holes") to have a list of what it applies to (object 14, 15, 18, 45)
10:46 PM rue_mohr: and I dont want to duplicate the lists, and their not really built around pointers
10:47 PM rue_mohr: typedef struct asdf_s {
10:47 PM rue_mohr: entityList_t *
10:47 PM rue_mohr: cncOp_t
10:47 PM rue_mohr:
10:47 PM rue_mohr: } asdf_t;
10:47 PM rue_mohr: but not
10:50 PM rue_mohr: how much to go down to the usa and get an mri?
10:50 PM rue_mohr: like cash down
10:52 PM zhanx: no clue
10:53 PM zhanx: but you will get better results than canada
10:54 PM zhanx: this 3d scanner has been waiting on lasers for 2.5 months. wow
10:54 PM zhanx: after this i am building a mini server
10:54 PM zhanx: code backup
10:54 PM rue_mohr: I got a shipment in 7months once
10:56 PM zhanx: still waiting on a mouse from 2 years ago
10:57 PM rue_mohr: yea, I hope you got a refund
10:57 PM zhanx: ordered a few fitting for my brewery on 11.11 to see how long till they get here, I did
10:58 PM zhanx: if i put about half as much enough in the brewery as i did the scanner it will be nice
10:59 PM zhanx: oh
