04:35 AM Tom_L: .
05:47 AM rue_mohr: .
06:18 AM Tom_L: .
10:05 AM aandrew: interesting strain gauge
02:19 PM rue_mohr: the article came up on hackaday a while ago
03:13 PM rue_mohr: 3720 steadily growing
04:34 PM Tom_L: closer to that autograph
04:34 PM rue_mohr: :]
04:39 PM polprog: sup rue_mohr
04:40 PM rue_mohr: your alive!
04:40 PM rue_mohr: I had all sorts of cool things to tell ya
04:40 PM polprog: i am!
04:40 PM rue_mohr: not sure what they were anymore
04:41 PM polprog: haha
04:41 PM rue_mohr: but it was cool
04:41 PM polprog: its ok
04:42 PM polprog: Rue you didnt see my 3d print raspi project
04:42 PM rue_mohr: ?
04:42 PM rue_mohr: did you post it on twitter?
04:42 PM polprog: https://tacobelllabs.net/@gorplop/109501775887836574
04:43 PM polprog: i forgot to post it to twitter
04:43 PM polprog: maybe I should
04:43 PM polprog: The crossposter service broke
04:43 PM rue_mohr: oh mastadon, it wont render for my browser
04:43 PM rue_mohr: like, it locks me out cause of my browser
04:43 PM polprog: ah shit
04:43 PM rue_mohr: can you try a link to the image direct?
04:44 PM polprog: https://tacobelllabs.net/system/media_attachments/files/109/501/770/633/970/636/original/8f732698e47fd3e8.jpg

04:44 PM rue_mohr: oh yea
04:44 PM rue_mohr: ok, you did give an earlier progress shot
04:44 PM rue_mohr: what is the keyboard from?
04:45 PM rue_mohr: oh its... hmmm
04:47 PM polprog: its a generic chinese mechanical
04:47 PM polprog: $15 or so
04:48 PM rue_mohr: oooo
04:49 PM rue_mohr: thats about $100 cheaper than the ones I could find
04:51 PM polprog: its quite nice for the price
04:51 PM polprog: it has the clicky noisy cherry MX switches but i cant complain for $15
04:54 PM polprog: https://polprog.net/rozne1/ircjunk/various/obj/raspi_kb_leggy.FCStd
04:54 PM polprog: this was just a test but i should have used openSCAD
04:54 PM polprog: that way id just send you the script and tell ya to measure your keyboard's height
04:55 PM polprog: or depth
05:45 PM polprog: nighters
08:42 PM Tom_L: rue_mohr,
08:43 PM Tom_L: who's gonna pull santa's sleigh with no reindeer???
09:01 PM rue_mohr: :/
09:01 PM rue_mohr: I'm not sure how to fix that thing
09:01 PM rue_mohr: I THINK casting aluminum around the tube and element might help
09:01 PM rue_mohr: that or it'll wreck the whole thing?
09:01 PM rue_mohr: :S
09:08 PM Tom_L: how's that trigger mold holding up?
09:11 PM rue_mohr: better than I thought
09:11 PM rue_mohr: I'v eaten out like 3 ladels
09:11 PM rue_mohr: but they have a longer exposure time
09:11 PM rue_mohr: apparently the aluminum alloys eat steel
09:59 PM Tom_L: are they getting pitted?
09:59 PM rue_mohr: nope
10:00 PM Tom_L: nice
10:00 PM rue_mohr: they have a nice coating of FeO3 on them
10:00 PM Tom_L: iirc i sent 2 sets.. one not so good
10:00 PM rue_mohr: I used them both last time, the latter works better
10:00 PM Tom_L: the funnel was different iirc
10:00 PM rue_mohr: having the sprue right on the big end makes it hard to remove
10:01 PM Tom_L: yeah i remember that now
10:04 PM rue_mohr: I wonder if I got a few too many driections going at once
10:05 PM rue_mohr: the scanner needs me to set up a new 24V power suppply
10:05 PM rue_mohr: I need to figure out templates for the schematics database
10:05 PM rue_mohr: I think I'll do it in javascript
10:06 PM rue_mohr: I need motor drivers to make servos
10:09 PM Tom_L: no more directions than usual
10:10 PM rue_mohr: the menu for motor drivers is diverse
10:10 PM rue_mohr: single or dial rail supply
10:11 PM rue_mohr: pwm/dir , FW/REV, or just pwm inputs
10:11 PM Tom_L: fwd/rev with pwm
10:11 PM rue_mohr: pwm/dir
10:11 PM Tom_L: the first one
10:11 PM Tom_L: yes
10:11 PM Tom_L: more control i think
10:12 PM rue_mohr: but you had that one that just switches it between forwards and reverse
10:12 PM rue_mohr: and , with the right inductance on the motor, that works
10:12 PM Tom_L: yeah it did ok
10:12 PM Tom_L: 50 50
10:12 PM Tom_L: pwm
10:12 PM rue_mohr: due to the inductance on the motor, the current wont have time to rise
10:13 PM rue_mohr: then comes the feedback from the motor
10:13 PM rue_mohr: analog pot or encoder
10:14 PM rue_mohr: which is really two worlds, absolute positioning and relative positioning
10:14 PM Tom_L: inductance
10:14 PM rue_mohr: should I try to dodge the weather and cast a block around the injection molder?
10:15 PM Tom_L: no clue
10:15 PM rue_mohr: its hard to know if its going to rain, and the casting sand was giving me grief
10:15 PM rue_mohr: I wasn't even awake long enough today to get much of the daylight
10:16 PM rue_mohr: I suppose this is why I did get the big flood lights
10:16 PM Tom_L: you gonna find work soon?
10:16 PM rue_mohr: I'm ok for a bit
10:16 PM Tom_L: not saving for a house
10:16 PM rue_mohr: the one organization says the buracracy is processing their position request
10:17 PM rue_mohr: after 15 years of saving, not having near enough money to even start a house means I'm not falling behind that quick
10:17 PM rue_mohr: I cant get the money I'll need via manual labor
11:19 PM rue_mohr: motor drivers
11:19 PM rue_mohr: there is another one
11:19 PM rue_mohr: synchronized pwm
