08:05 robotustra hi
09:31 rue_house hi
09:31 rue_house its morning, this will be proceeded by 9 hours of complete silence
11:45 wolfmanjm shhh.. you're kicking up dust ;)
19:58 rue_house yay! SOMEONE said something
19:58 Tom_itx got my PATA adapter today
21:00 rue_house I got 10x 7x9 pcb's from china today
21:01 Tom_itx nice
21:01 Tom_itx what are they for?
21:04 rue_house stock
21:05 rue_house I have a sneaking suspicion that the ability to just get things from china like we can now is gonna be a day past
21:05 Tom_itx i wonder if ghost would work on a usb drive
21:06 rue_house I wonder if ghost can do anything partimg cant
21:06 Tom_itx i don't know about parting?
21:07 Tom_itx is that linux?
21:07 rue_house yup
21:07 rue_house I'v never successfully used ghost
21:07 Tom_itx i'd rather not experiment on this
21:07 Tom_itx i've used ghost multiple times with 100% success
21:10 Tom_itx rue_house, do you have a way to test parting on USB?
21:17 rue_house ghost must work, everyone uses it, last windows thing like that I used was partition magic
21:17 rue_house usb partitions?
21:17 Tom_itx no just read from a USB drive to ghose or parting it
21:18 rue_house well I just do
21:18 rue_house whats complicated?
21:18 Tom_itx have you done that?
21:18 Tom_itx use USB as the source drive?
21:18 rue_house pretty sure I have yea
21:18 Tom_itx do you have the cmd line i need for that?
21:18 rue_house to do what?
21:19 rue_house make a second partition?
21:19 rue_house read a partition
21:19 Tom_itx NO!
21:19 rue_house what you want to do isn't clear
21:19 Tom_itx copy one drive to another
21:19 Tom_itx mirror it
21:19 rue_house you just mount it and copy the files
21:19 rue_house or copy it raw
21:19 Tom_itx i want the whole thing
21:19 rue_house k
21:19 rue_house same model drives?
21:19 Tom_itx will linux copy a windows drive?
21:19 Tom_itx no not the same models
21:20 Tom_itx that's why i was after ghost and partition magic
21:20 rue_house if its not the same model drive, then the partitions will be different sizes and youhave to do the copy at a file level
21:21 Tom_itx i'll use ghost and partition magic
21:21 rue_house Iv done it with linux tools, but why not just use what your used ot?
21:21 Tom_itx i know it will do that
21:21 Tom_itx ok
21:21 Tom_itx because i was open to learning something
21:21 rue_house :)
21:21 rue_house ah
21:22 Tom_itx i'm content to stay dumb as a rock though
21:22 rue_house the files aren't as hard to move around as the bootloader :)
21:22 Tom_itx i'm aware
21:22 rue_house well play with them later when there is no pressure
21:23 rue_house aha! I found the EMC isntaller drive!
21:23 rue_house have to find a computer...
21:23 Tom_itx YES!
21:23 Tom_itx it's about damn time!!!
21:25 rue_shop2 oh not now, want to work on my arm
21:25 Tom_itx fooey
21:28 rue_shop2 I been pulling LOTS of generic stepper motor driver boards from HP printers of late, and I bet I could speed up my cnc 4x with them
22:45 rue_shop2 with all the rotational errors on this robot i can see that setting up the kinematics isn't gonna be a walk in the park
22:50 rue_shop2 I need a takeup mechanism
22:50 m_itx gives rue_shop2 a s
22:50 rue_shop2 something different than the tension spring
22:51 rue_shop2 I shoud post the images of this arm
22:51 rue_shop2 I'm getting alittl embarrased about how many hours I put into it
22:51 Tom_itx clock mainspring
22:52 Tom_itx retractable tape measure
22:52 Tom_itx same idea
22:52 rue_shop2 hmm
22:52 rue_shop2 I cant fit this next one I need to do IN the pulley, its too small
22:53 Tom_itx i wonder if i need to fdisk before ghost
22:54 Tom_itx i forget
22:54 Tom_itx i don't think so
23:06 rue_shop2 I keep making spare peices for these robot arms and throwing them in a box
23:06 rue_shop2 its starting to get quite a collection
23:10 Tom_itx is it like your stepper collection? or your gear collection or....
23:19 rue_shop2 hmm not yet
23:20 rue_shop2 but there are now 4 (well 3.8) robot arms on the work table
23:21 rue_shop2 well 10" arms
23:21 rue_shop2 there is the big one bolted to the far corder
23:21 rue_shop2 corner
23:37 Tom_itx ok that went well
23:46 rue_house bootable?
23:46 Tom_itx yeah
23:47 rue_house "the burrito, often mistaken for a chillidog, is not a chillidog, but infact a burrito, this gave it the name "california chillidog" it is, however, still a burrito"
