12:00 AM rue_shop3: wow, self zippering actuators!
12:03 AM rue_shop3: The_Jester, about how many peices to it?
12:04 AM The_Jester: 16 i think
12:05 AM The_Jester: going to need a bunch of filler thats for sure :(
12:08 AM rue_shop3: hmm
12:14 AM The_Jester: certainly not going to go crazy
12:20 AM mrdata: no?
12:25 AM The_Jester: if i was insane i would print it at 100%, smooth it, pour a mold and cast in actrylic rince and repeat
12:28 AM mrdata: i see
12:56 AM rue_shop3: bondo
01:04 AM mrdata: krazy glue
01:31 AM rue_shop3: hmm
01:32 AM rue_shop3: ok wtf
01:32 AM rue_shop3: one more thing before bed or not?
01:32 AM rue_shop3: no, the printer is busy
01:34 AM rue_shop3: hmm I'll come back in a bit and check on the cnc
01:34 AM rue_shop3: dont know if its gonna jog properly
04:03 AM Jak_o_Shadows: Let's check that y-axis!
04:09 AM Jak_o_Shadows: step 1: turn printer on
04:09 AM Jak_o_Shadows: step 2: try to connect
04:09 AM Jak_o_Shadows: step 3: plug in printer to computer
04:09 AM Jak_o_Shadows: step 4: actually connect
04:45 AM Jak_o_Shadows: I know why the y-axis is slipping!
04:45 AM Jak_o_Shadows: the grub screw came out of the gearthingo
04:45 AM Jak_o_Shadows: I did wonder where that grub screw I found came from
05:05 AM Jak_o_Shadows: wait, no, screw still in there
09:25 AM rue_house: oh you dont have those horrid printed bits held onto the motor with a grub screw thru the plastic do you?
09:26 AM rue_house: aaaaaar
10:06 AM LuminaxWk is now known as Luminax
11:37 AM rue_shop3: hahaha, I was going to a lot of effort to collect 2SC4242 for driving the pneumatic solinoids,
11:37 AM rue_shop3: which ohm out at 1k
11:37 AM rue_shop3: so, thats about 80mA
11:37 AM rue_shop3: so, its only trickey cause of the 80VDC
11:38 AM rue_shop3: but it looks like a loley 2N5551 will do just fine
11:38 AM rue_shop3: I have a bunch of them, cause they work as oscillators when the CE is reverse biased
11:38 AM rue_shop3: haha
11:41 AM rue_shop3: huh MPSA42 is also on the list
11:43 AM rue_shop3: the mecha has 47 actuators
11:43 AM rue_shop3: x4 valves...
11:44 AM rue_shop3: 200 transistors
11:44 AM rue_shop3: aka, $3
11:48 AM rue_shop3: ok, off to work
12:33 PM BitEvil is now known as speedevil
12:34 PM speedevil is now known as SpeedEvil
02:00 PM mynameis: sppedevil
02:00 PM mynameis: so basically the navspark ublox
02:00 PM mynameis: and a more expensive raech
02:00 PM mynameis: are the cheapest solution
02:00 PM mynameis: to rtk
02:01 PM mynameis: system
02:04 PM synja: rue_shop3, do you change out your old platters in HDDs?
04:58 PM Xiao is now known as SAXiao
06:15 PM synja: lol i lost a screw for one of my hands
06:15 PM synja: looks like they'll be used for jazz hands for now on
08:20 PM rue_bed: mynameis, your buying an ik package?
08:20 PM rue_bed: synja, no, I do not repair hard drives
08:20 PM rue_bed: raid and replace
08:21 PM synja: they're bad enough
08:21 PM synja: i just had one function on it i wanted
08:21 PM synja: lmao
08:21 PM synja: it was a _great_ function
08:22 PM rue_bed: better than my LinearInterpolateMultiAxis()?
08:22 PM rue_bed: er , SimotaniouslyLinearlyInterpolateMultiAxis()
08:22 PM rue_bed: I should just copy it from the source
08:23 PM synja: it's about 50 lines of heavy code
08:23 PM synja: related to learning nlp from conversations
09:20 PM rue_bed: The_Jester, hey
09:26 PM The_Jester: hey
09:26 PM The_Jester: so whats with the bondo?
09:54 PM rue_house: The_Jester_Kicke, smoothest model ever dude
09:54 PM rue_house: its on you now
09:54 PM rue_house: biab
09:55 PM The_Jester_Kicke: geez, high standards for a guy who usually doesnt put much effort into finishing details
09:58 PM The_Jester_Kicke: will try my best anyway before trying the terminator arm
09:58 PM The_Jester_Kicke: would be easier if id prinjted it at 100%
10:13 PM rue_house: me and the guy figured that would be eenough for about 200 models
10:13 PM rue_house: just dealing with yard stuff, back in a bit
10:37 PM rue_house: The_Jester_Kicke, ok, I'm back
10:40 PM rue_house: The_Jester_Kicke, so?
10:41 PM rue_house: why do I always get vistors when people are trying to talk to me on the internet?
10:51 PM rue_shop3: ugh
10:52 PM Xiao is now known as SAXiao
11:16 PM mrdata_ is now known as mrdata
11:38 PM rue_shop3: The_Jester_Kicke, well, if your still online, and I only get one more thing to say, I say this "its not too special, just use it"
11:46 PM rue_shop3: veverak,
11:46 PM rue_shop3: it looks like I'm going to write the 40 servo STM32 code
11:46 PM rue_shop3: the code I need for the mecha solinoid control is almost identicle
11:47 PM rue_shop3: I need to run 32 solinoids/ controller
11:47 PM rue_shop3: which is 8 channels on 4 expansion chips
11:47 PM rue_shop3: so, +- its the same thing
11:47 PM rue_shop3: different scale, but whatever
11:48 PM rue_shop3: this morning I worked out that I can use stupid-small transistors for the solinoids
11:48 PM rue_shop3: and I just proved out the opto isolated driver
