12:17 AM katsmeow: Mountaineering in dream= <jmp> Mountain in dream
12:17 AM katsmeow: Mountain in dream= Mountains can often symbolize challenges or obstacles in your life. There are several things to consider about mountains in a dream. How high or large is your mountain? Where are you physically located in regards to the mountain itself? Are you at the base looking up, or are you on the summit looking down? All of these questions may give you a perspective on the nature of
12:17 AM katsmeow: an obstacle you are currently confronted with in your waking life. It is also important to consider the way in which confronting the mountain makes you feel. Another factor to think about is the geographical location of the mountain. Is the mountain where you would expect it to be? Or is it perhaps rising from a swamp, a cloud, or someplace in a house?
12:17 AM katsmeow: Mountain in dream= All of these things can be important. If you feel that the mountain is a negative obstacle in your life, try to imagine what the dream landscape would be like if the mountain were smaller, or all together removed.

12:22 AM katsmeow: you asked
12:22 AM katsmeow: sorry
12:22 AM rue_: http://ruemohr.org/~ircjunk/images/p1100614.jpg
12:22 AM katsmeow: 105,221 lines is a ton of data snippits
12:22 AM rue_: I'll prolly need a cap around the comparitor to limit the switching freq eh?
12:23 AM katsmeow: i am unfamiliar with that stepper
12:23 AM rue_: 5 wire, current driven
12:24 AM katsmeow: uhhhhhhhhhhhh
12:24 AM katsmeow: what are those tristate buffers that pull 1.5amps on the enale pins?
12:24 AM katsmeow: enable
12:25 AM rue_: no open collector drivers
12:25 AM rue_: with flyback diodes
12:25 AM rue_: MP4301 ask tigger :)
12:26 AM katsmeow: your comparators will toggle at almost the same time, you have given them identical signals
12:26 AM katsmeow: she doesn;t know
12:27 AM rue_: only one is supposed to be on at a time
12:27 AM katsmeow: it's not in my db either
12:27 AM rue_: whaaaa
12:27 AM rue_: you got some fancy stuff
12:27 AM rue_: thats just a simple driver array
12:28 AM katsmeow: why ot use a 7474 then, it's guaranteed to not have Q and not-Q on at same time, unless you force it
12:28 AM rue_: its going into a microcontroller, ther 7406 might not even be there in the end
12:29 AM rue_: its that placeholder gate in the diagram
12:29 AM * katsmeow stops looking then
12:29 AM katsmeow: i remember you were asking me about a circuit once that you had already changed
12:29 AM rue_: the concern is about the comparitors current control
12:29 AM rue_: I kinda blitz when I'm finding a design
12:30 AM rue_: close to parallel as I can
12:30 AM katsmeow: ok, current goes up, positive rising edge toggles the 7474 (negative will toggle a 4013)
12:30 AM rue_: oh
12:30 AM rue_: oh I see
12:30 AM katsmeow: if you put one comparator on the .33 ohm, you can adjust the current toggle threshold
12:30 AM rue_: yea, ok
12:31 AM rue_: but then Iwas gonna put a cap around the comparitor to hold it reset for ... a time
12:31 AM rue_: its a lm339, so, good fast comparitor
12:31 AM katsmeow: to reset? putting dc on a coil ?
12:32 AM rue_: 'reset' -> keep the comparitor off
12:32 AM rue_: /|/|/|
12:32 AM rue_: prolly
12:32 AM katsmeow: but then the lines won;t get toggled, and current will sktrocket on the one energised coil
12:32 AM rue_: /|_/|_/|
12:33 AM rue_: it should keep the current limited tho
12:33 AM katsmeow: skyrocket
12:33 AM rue_: I got the comparitor polarity backwards?
12:33 AM rue_: the 4301 is an inverting driver
12:33 AM katsmeow: we must not be talking about the same thing
12:34 AM katsmeow: it's after midnite anyhow, my brains are off, and i ate a sleepy pill an hr.5 agho
12:34 AM rue_: so, the 7406 lets go of the signal, 1k pulls it up, the driver turns on, the coil current starts rising
12:35 AM rue_: the current trips the comparitor, driving the control line low, turning off the coil, and its current starts to fall
12:35 AM rue_: the filter bleeds off, the comparitor clicks back in, turns the coil in for another cycle
12:35 AM katsmeow: so it isn;t 2phase?
12:36 AM rue_: no, 4 phase
12:36 AM katsmeow: and you are driving only one coil?
12:36 AM rue_: but you should only be driving 2/4 coils at once
12:36 AM katsmeow: so that is 1/2 of the total schematic?
12:36 AM rue_: 2 is better, its the same pattern as the 2 phase, but you use the other coil instead of reversing the polarity
12:36 AM rue_: yes
12:37 AM rue_: ... I coulda mentioned that earilier?
12:37 AM rue_: other 2 coils are identical circuit
12:37 AM * katsmeow rolls her eyes
12:38 AM rue_: lm339 has 4 comparitors, the 4301 is a 4 channel driver
12:38 AM rue_: but the 4 outputs are split into 2 emitter circuits for doing exactly this
12:39 AM * katsmeow would have done it differently
12:39 AM rue_: pls tell (ok, 7474...)
12:42 AM katsmeow: no, for 4phase, a 74164 and a couple gates to me the DESIRED 4 phase pattern, feed the 4 phases to a 4066 (etc) to gate them on/off, put the one comparator on the current sense R, to set current, feed that to a 74221 you can adjust with a pot to set your off-time, the 221 triggers the 74164 again
12:43 AM katsmeow: maybe you can yse a 555 instead of the 221/223/123, but i would stay with the ttl logic
12:44 AM katsmeow: 74121= [!what][!electronics][!integrated circuit] Monostable Multivibrator
12:44 AM katsmeow: 74122= [!what][!electronics][!integrated circuit] Retriggerable Monostable Multivibrator with Clear
12:44 AM katsmeow: 74123= [!what][!electronics][!integrated circuit] Dual Retriggerable Monostable Multivibrator with Clear
12:44 AM rue_: your using a 1/4 johnston sequence then?
12:44 AM rue_: how about the NE558, a quad timer
12:45 AM katsmeow: o, just saying with the 164, you can generate one on per phase, 2 on per, or every other one on
12:45 AM katsmeow: 558 won;t synch on perfectly timed 4 phases
12:46 AM rue_: k
12:47 AM rue_: :) I overpaid my last telephone bill by 3.14 to make sure they were carrying credit forward properly
12:47 AM rue_: yup
12:48 AM katsmeow: you xan make 0000 > 1000 > 1100 > 0110 > 0011 > 1001 > etc
12:48 AM katsmeow: or
12:48 AM katsmeow: 0000 > 1000 > 0100 > 0010 > 0001 > 1000 > etc
12:48 AM katsmeow: or
12:49 AM rue_: did I tell you my idea of using 8x8 led arrays as OTP ROM arrays for an FSM?
12:49 AM katsmeow: 0000 > 1000 > 0100 > 1010 > 0101 > etc
12:49 AM katsmeow: eyeas
12:49 AM rue_: katsmeow, I'd have thought it was more complex, but I see how that 164 circuit can do all that, huh, cool
12:49 AM rue_: I need to make a led array 'burner'
12:50 AM rue_: not sure of what kinda pulse to burn off the bond wire and leave the internal traces in tact
12:50 AM katsmeow: i dunno, brain is almost all off atm, a probl;em with biology
12:51 AM rue_: yes, I need to got o bed
12:51 AM rue_: goto(bed)
12:51 AM rue_: 20 GOTO BED
12:52 AM katsmeow: you can preload a sheft register, or give it the right input on the serial pin,, the preloading is easiest by far
12:53 AM * katsmeow waves gnites
12:53 AM rue_: a 75151(?) can be used as a data selector to fedd th next bit
12:53 AM katsmeow: ok
12:54 AM rue_: And that wraps up another programming day here at #garfield, see us in 8 hours when rue says "Anyone seen my tea mug?"
12:55 AM rue_: till then, farewell and goodnight.

11:54 AM ffurrywol is now known as furrywolf
08:16 PM rue_shop3: my indian head came out really horrid in non-monospace font
08:17 PM Tom_L: is that wtf you were up to?
08:17 PM Tom_L: i thought you went bonkers and started spamming like the rest
08:19 PM rue_shop3: monospace font
08:19 PM rue_shop3: its the old test pattern
08:20 PM rue_shop3: hah, I flicked a mosquito and its legs stayed behind!
08:20 PM rue_shop3: haha
08:21 PM Tom_L: have to belly land now
08:29 PM Tom_L: ok so is there a mode switch to silence a user unless they're registered instead of not letting them join?
08:30 PM Tom_L: because i think that's what the other channel is doing and the bot is able to join there with no problems
08:30 PM Tom_L: ^^ rue_shop3's homework
08:30 PM furrywolf: /mode +q $~a
08:31 PM Tom_L: you sure?
08:31 PM furrywolf: yes
08:31 PM Tom_L: what's the $~a do?
08:31 PM furrywolf: some magic in the freenode ircd that quiets unidentified nicks. :)
08:32 PM Tom_L: are you registered?
08:36 PM Tom_L: hmm i guess that would work
08:36 PM Tom_L: https://gist.github.com/jjasghar/257263196a8219490252
08:36 PM Tom_L: handy bit of info there
08:43 PM rue_shop3: drat, cant open github links
08:44 PM rue_shop3: her
08:44 PM rue_shop3: e
08:44 PM rue_shop3: what is it?
08:44 PM Tom_L: open it
08:44 PM Tom_L: i'm gonna change the +r
08:44 PM Tom_L: and see if it works
08:44 PM rue_shop3: I'd have to switch computers
08:44 PM Tom_L: ok
08:45 PM Tom_L: but i'll add a message link in the topic
08:45 PM Tom_L: http://git.io/zrffqw
08:45 PM rue_shop3: cant open any git links on this computer
08:45 PM Tom_L: so switch to another pc
08:46 PM rue_shop3: I'm doing stuff
08:46 PM Tom_L: you need some tea anyway
08:46 PM Tom_L: do it@
08:46 PM Tom_L: !
08:46 PM rue_shop3: later
08:46 PM Tom_L: later will be too late
08:51 PM Tom_L: ok let's try that a while
08:52 PM Tom_L: the bot is able to join that way
09:15 PM Tom_L: i changed #avr too
09:30 PM Tom_L: must be busy building an index
10:54 PM katsmeow: https://www.wired.com/story/google-location-tracking-turn-off/
10:58 PM Tom_L: well it finally caught up with itself i think
11:01 PM zhanx: yep
11:01 PM zhanx: its why i am working on this home assistant without google
11:01 PM katsmeow: please post detailedplans of how anyone can make their phone turn on their house lites
11:02 PM zhanx: which control would you like to use? i am using esp8266's (wemdos d1 minis)
11:02 PM katsmeow: i have no clue
11:02 PM zhanx: google up sonoff
11:03 PM zhanx: they are cheap 10a rated controllers that can be flashed to use them without the cloud
11:05 PM katsmeow: i have relays
11:05 PM zhanx: for the home control software, i am using Home-assistant.io
11:05 PM zhanx: it is open source
11:06 PM zhanx: for me the key is wireless relays
11:06 PM zhanx: but you can run wires if have gpio out for the computer it runs on
11:07 PM katsmeow: permantly installed devices can have cat5 run to them when they are installed, the rest can be wireless
11:07 PM katsmeow: cat5 can be used generically, to carry power and 4 channels of serial data
11:26 PM * katsmeow debates going afk to be productive
11:27 PM rue_shop4: hi kat
11:28 PM katsmeow: hi rue
11:28 PM rue_shop4: katsmeow, so, the 4301 driver chip, it sucks, too much
11:28 PM rue_shop4: 1.5V drop
11:29 PM rue_shop4: with *any* load it gets really hot
11:29 PM katsmeow: i dunno that chip, but the, i dunno many bad ships
11:30 PM rue_shop4: and todays magic value is 650 ohms
11:30 PM katsmeow: why not use a good lil to220 mosfet 386 to drive it?
11:30 PM rue_shop4: hmm
11:30 PM rue_shop4: irfz44
11:30 PM rue_shop4: yes
11:31 PM katsmeow: ok, and LM386 drive it
11:31 PM katsmeow: or the IRF49..... something Pchannel that's almost as good
11:31 PM rue_shop4: I have a 2N7000 & 2n2222 circuit that drives a fet clean up to 1Mhz
11:32 PM rue_shop4: (my freq gen cant go past 1Mhz)
11:32 PM rue_shop4: wtf do I use for "650 ohms"
11:32 PM rue_shop4: 580... 820
11:33 PM katsmeow: ok
11:33 PM katsmeow: i dunno it's purpose
11:34 PM katsmeow: IRF4905
11:35 PM katsmeow is now known as katsmeow-afk
11:36 PM rue_shop4: heh, I used a pot to trim a circuit
11:37 PM rue_shop4: now I need the static value, but I changed the cap instead and it tuned up to 300R
11:37 PM rue_shop4: 330R
11:37 PM rue_shop4: which works fine
11:37 PM rue_shop4: but there are no.... 720 is a standard?
11:37 PM rue_shop4: there are no 6xx standard values...
11:38 PM rue_shop4: ok I have a circuit that works nice
11:38 PM rue_shop4: few more parts...
