12:00 AM rue_mohr: so, sand mix, what ya got?
12:05 AM zhanx: 3" bottom and top?
12:05 AM zhanx: bentonite, sand and oil
12:05 AM rue_mohr: oil based ok
12:05 AM zhanx: like you I have been looking at stuff etc, but need to just do it
12:06 AM zhanx: yea but I want to cast from 3d printed stuff (not melting unless I have to)
12:06 AM rue_mohr: yup
12:07 AM zhanx: i have an "idea" for the feet of the next elf i want to test
12:07 AM zhanx: hence the winding of the motors and size
12:07 AM rue_mohr: remember, the whole goal is to make a cavity the shape you want, how you do it doesn't matter
12:08 AM zhanx: true
12:08 AM zhanx: and from your casts,VENTS
12:08 AM rue_mohr: that fact caught me off guard
12:08 AM rue_mohr: yup, but eth sand is supposed to be porus too
12:09 AM zhanx: well a motor is a motor and can be a magnet at the same time
12:09 AM rue_mohr: it should allow gas to get into it a bit, and steam(s) to get out
12:09 AM zhanx: that did't come out right but i think you get it
12:09 AM rue_mohr: :)
12:10 AM rue_mohr: you need a proper camera and place to post proejct photos
12:10 AM zhanx: yes i do, server is almost done for that, need real internets not cell ones also
12:12 AM rue_mohr: still?
12:12 AM rue_mohr: did you apply for a job with them?
12:12 AM zhanx: still and yes i did today
12:12 AM zhanx: oh crap cube is printed with no infill, oops
12:12 AM rue_mohr: funny to have to work for soemone to get the inside info to install your internet
12:13 AM zhanx: never know i might like it
12:13 AM rue_mohr: but *&%&*^$^
12:13 AM rue_mohr: yea, atleast its that opportunity
12:13 AM rue_mohr: in 3 days you might be their top guy
12:13 AM rue_mohr: :)
12:13 AM zhanx: oh wait i did 1% infill this should be funny
12:14 AM zhanx: rue never know
12:14 AM rue_mohr: is it acceptable to take 1.5secoonds to measure a 1Hz signal?
12:14 AM zhanx: either way i am tired of contracting and dealing with payments
12:14 AM zhanx: and NO
12:14 AM rue_mohr: hmm
12:15 AM zhanx: i t w i l l measured like that
12:15 AM rue_mohr: hmm I suppose it could be longer too, if it started just after a transition
12:16 AM rue_mohr: yea, I have a feeling this low freq stuff will be patience testing
12:16 AM rue_mohr: and, is 1Hz low enough for testing servos...?
12:16 AM zhanx: took 5 kg of filament for the frame for the large scale printer
12:16 AM rue_mohr: hah
12:16 AM zhanx: double i think
12:17 AM rue_mohr: you think 2Hz is ok?
12:17 AM zhanx: wish i had the notes from elf still
12:17 AM zhanx: you helped me measure that before
12:17 AM rue_mohr: I want to know the -3db of a 5g servo :)
12:17 AM zhanx: either way new body design is started
12:18 AM rue_mohr: gueses? 3hz? 5hz?
12:18 AM zhanx: 3
12:18 AM zhanx: 2.7
12:18 AM rue_mohr: I'm a ways from finding out :(
12:19 AM zhanx: was it kat that helped me measure that?
12:19 AM zhanx: been 11 years+
12:20 AM zhanx: dumb question, if i want to add mass to the parts for machining, wax or ?
12:20 AM rue_mohr: I wonder if the esp8266 is rebooting from a divide by zero fault
12:21 AM zhanx: power issue i bet
12:21 AM rue_mohr: well it could be
12:21 AM zhanx: that was my number 1 issue with them, power hogs
12:21 AM rue_mohr: thats fancy machinging stuff I dont know
12:21 AM rue_mohr: its got a 2A 5V adapter
12:22 AM zhanx: k, i think i will do some wax dips to add mass so i can machine the sand off easier
12:23 AM rue_mohr: Duty = a*100/p; // duty
12:23 AM rue_mohr: hmmmm
12:24 AM zhanx: that guy last night i was helping
12:24 AM zhanx: pot to stepper controller
12:24 AM rue_mohr: k
12:24 AM zhanx: first time with avr
12:24 AM rue_mohr: heh
12:24 AM zhanx: 4 or 5 declares for all values
12:25 AM zhanx: in all functions
12:25 AM zhanx: didn't know any better etc
12:25 AM zhanx: but its working now for him, so good
12:25 AM rue_mohr: pot to stepper is pretty easy
12:25 AM zhanx: for us
12:25 AM rue_mohr: k
12:26 AM rue_mohr: hard first project, for sure
12:26 AM zhanx: for an artist not so much
12:26 AM zhanx: and his pot was a smart phone etc
12:26 AM zhanx: make the bird flap faster in the art scene
12:26 AM rue_mohr: I protected that division, see if it stays up now or not
12:26 AM rue_mohr: :) nice
12:27 AM zhanx: college kid, stage hand class
12:27 AM rue_mohr: nice
12:27 AM rue_mohr: so, I'm pretty sure I should add manual controls to the tea machine
12:28 AM rue_mohr: maybe an indicator led and a on/off toggle
12:28 AM rue_mohr: (button)
12:28 AM zhanx: want my label maker?
12:28 AM rue_mohr: ?
12:28 AM zhanx: to label the button
12:28 AM rue_mohr: heh
12:29 AM rue_mohr: it would be nice to be in the kitchen and not have to walk to my bedroom to start the tea
12:29 AM zhanx: this cabin has a sliding glass door, its looking like its gonna be a white board soon for me
12:29 AM rue_mohr: 1st world problems
12:30 AM zhanx: don't make me boston tea party your house
12:36 AM rue_mohr: the test is if its still on in the morning
12:36 AM rue_mohr: I have another codeproblem to solve on it
12:36 AM rue_mohr: it has a sense line thats indicates if the element is on
12:36 AM rue_mohr: BUT
12:37 AM rue_mohr: apparently, when the element is on, you get 60Hz on it...
12:37 AM rue_mohr: so I have to software-out the 60hz, meaning hell if I know when it actually turned off
12:39 AM rue_mohr: I wonder if I just reset a tracker and keep track of numbers greater than 1/60sec
12:56 AM rue_mohr: hahah I took a melitonin and I'm trying to code
12:56 AM zhanx: weighed in today
12:56 AM zhanx: 274
12:57 AM zhanx: 12.3% body fat
12:57 AM rue_mohr: what is the target number?
12:58 AM zhanx: 5-6% body fat
12:58 AM rue_mohr: oh
12:58 AM zhanx: about 260-265 due to my size
12:59 AM rue_mohr: bench press more goats?
12:59 AM rue_mohr: :)
12:59 AM zhanx: lol
12:59 AM zhanx: not steppy on laptops also
12:59 AM rue_mohr: state = digitalRead(5);
12:59 AM rue_mohr: digitalWrite(2, !state); // update element status led.
12:59 AM rue_mohr: if (state == HIGH) t = millis(); // reset on every high
12:59 AM rue_mohr:
12:59 AM rue_mohr: if (( millis() - t) > 18) { // an off is happening
12:59 AM rue_mohr: EState = 0;
12:59 AM rue_mohr: } else { // an on is happening
12:59 AM rue_mohr: EState = 1;
12:59 AM rue_mohr: }
01:00 AM rue_mohr: then I can trip on the Estate changing?
01:00 AM rue_mohr: and measure duty?
01:00 AM rue_mohr: andits just 16ms latency?
01:00 AM zhanx: why does that look wrong
01:00 AM rue_mohr: its evil
01:00 AM zhanx: oh
01:00 AM rue_mohr: I get 60hz pulses when the element is on
01:01 AM zhanx: your reading 3 states before you process them
01:01 AM rue_mohr: hmm
01:01 AM rue_mohr: I suppose the pulse is 1/120 of a second
01:01 AM rue_mohr: so I should be 8ms
01:02 AM rue_mohr: 20 seems like a safe number
01:02 AM zhanx: thats why i hate arduino code cause you never know
01:03 AM rue_mohr: I dont know there is much I could do with raw coding an esp8266
01:03 AM rue_mohr: lots of c++ libraries for the networking
01:03 AM zhanx: wrappers tho screw stuff up, but i know what you mean
01:12 AM rue_mohr: I think the divide by zero was resetting it, casue its still on
01:12 AM rue_mohr: see if my new duty code works
01:17 AM rue_mohr: aha! 16%
01:18 AM rue_mohr: 36% still a realistic number
01:18 AM rue_mohr: I guess I'll see
01:19 AM rue_mohr: mel says gnight
08:51 AM rue_mohr: Duty is: 124%
08:51 AM rue_mohr: hmm
