12:00 AM AltJesteR: want a 12v trucker fan for anything, I thought it was 110 when i saved it from the dump
12:03 AM rue_house: but, different, exciting, hexapod...
12:03 AM AltJesteR: can i fuck it?
12:03 AM rue_house: hmm
12:03 AM rue_house: we just need to lower our morals and its all good
12:03 AM rue_house: I'm sure with a silicone extruder on a 3d printer your set
12:03 AM rue_house: or go kinkey and use chocolate
12:03 AM AltJesteR: ouch
12:03 AM AltJesteR: im not putting my Benis anye=where near that thing
12:03 AM AltJesteR: almost time for more black
12:03 AM rue_house: how many times do I have to wash me hands before they feel clean?
12:03 AM rue_house: AltJesteR, bad topic switch dude
12:03 AM AltJesteR: try brake kleen
12:03 AM ace4016: douse them in gasoline, then wash them rue
12:03 AM rue_house: and, if I was a robot would I feel any cleaner?
12:03 AM AltJesteR: thing:573050
12:03 AM rue_house: ace4016, bah, if I use either I can just flash it off right?
12:03 AM AltJesteR: if you were a robot you would feel...err rust i amagine
12:03 AM ace4016: hehe
12:04 AM rue_house: hmm
12:04 AM AltJesteR: thing:573050 - next
12:04 AM AltJesteR: must make note, if it x or y that slips
12:04 AM * AltJesteR ponders
12:05 AM rue_house: oh, pondering, I didn't do pondering today
12:08 AM AltJesteR: ponder this, while im at work either this print will go really good or really bad
12:10 AM AltJesteR: bye Annie
12:14 AM AltJesteR: goodnight rue: Im off to my oph
12:14 AM rue_house: good luck with theprint!
12:15 AM AltJesteR is now known as The_jester_Atwor
12:15 AM The_jester_Atwor: fingers crosses its no a flaky driver or something stupid
12:20 AM rue_house: Jak_o_Shadows, had a good one, the driver failed, reverse only
12:30 AM rue_house: The_jester_Atwor, damn, you keep suggesting things for ebay to nag me about
12:31 AM rue_house: its found all the apple case emblams in the world and wants to know if I'd like to buy any of them
12:41 AM rue_house: I sleep now
12:42 AM rue_house: I'm going to have a long day tommroow trying to help somone with a technical thing that has no technical knowhow at all, and keep falling in it
12:42 AM rue_house: always makes for a long day
12:42 AM rue_house: I should prolly simplify the whole thing
12:42 AM rue_house: how many years should I go between upgrades to my computer?
12:43 AM rue_house: one more, your not spending now
12:44 AM rue_house: I think lieing in my bed keeps me awake
01:34 AM Luminax-Work is now known as LuminaxWk
06:12 AM veverak: so, there is li-po chargin circuit with solar panels
06:12 AM veverak: I will use multiple cells of LiPo battery
06:13 AM veverak: it seems like simple circuit, that will switch the charger between each cell, based on which has lowest voltage
06:13 AM veverak: could do the trick
09:20 AM rue_house: like to see how they did the switching
09:21 AM rue_house: Jak_o_Shadows, you get any of that?
09:22 AM veverak: rue_house: nobody did yet, I am thinking of it
09:22 AM rue_house: ah
09:23 AM rue_house: then I suggest boosting it to the array voltage and taking taps off the booster to each cell such that the cells are the total voltage across the booster
09:35 AM rue_house: ooo never thought ofpushing two sources in at once either
09:37 AM rue_house: I wonder what the typical feedbak gain is on a hobby servo
09:38 AM rue_house: I suppose...
09:38 AM rue_house: if you have a max duration of 2.5ms, and a max interval of 20ms
09:39 AM rue_house: or for that matter 2ms and 20ms it would be 10
09:39 AM veverak: rue_house: I was thinking of arduino controlling which cell is charged and switching it
09:39 AM veverak: also reporting the voltage levels on i2c or something
09:40 AM veverak: could be simple enough and I've got voltage monitor
09:40 AM rue_house: yes, unless you have a number of relays the switching can be trickey because of the polarities
09:40 AM rue_house: I have one that works like that for a 6 cell pack,
09:40 AM rue_house: uses 5 relays
09:40 AM veverak: I was thinking of two to three cell pack
09:41 AM veverak: with three relays, (I want option to not to charge anything)
09:41 AM rue_house: my robots a 6S6P :P
09:43 AM veverak: :))
09:43 AM * veverak likes small things
09:43 AM veverak: want to use 2S/3S battery pack in my boat
09:43 AM synja: hey, if anyone wants some code, just ask alicia
09:43 AM veverak: with solar panels to charge it, could be cool
09:43 AM synja: like, alic1a get code to shutdown in linux
09:43 AM alic1a: synja: sudo /sbin/shutdown -h now
09:44 AM synja: alic1a, thank you
09:44 AM alic1a: synja: Rly? . Do Not mention it.
09:45 AM rue_house: alic1a get state machines for sentient AI
09:45 AM synja: she wont respond to anything anyone but me says, but for code
09:45 AM rue_house: alic1a get code for state machines for sentient AI
09:46 AM synja: i doubt that will return anything
09:46 AM rue_house: if it does, were set
09:46 AM synja: ha
09:46 AM synja: nope
09:46 AM rue_house: otherwise she's not bootstrappable yet
09:46 AM synja: guess not
09:46 AM synja: alic1a, get code to reservoir sampling in lisp
09:47 AM synja: let's see
09:47 AM alic1a: synja: (defun pick2 (sequence n &aux (len (length sequence))) (labels ((pick2 (indices elements n) (if (zerop n) ; if no more elements are needed, elements ; then return elements. (let ((i (random len))) ; Otherwise, pick an index i. ;; If it's been used before, (if (member i indices) ;; then continue on with the same indices,
09:47 AM synja: w00t
09:47 AM synja: gotta be a little specific ;)
09:48 AM rue_house: alic1a, get code for NLP in C
09:48 AM synja: don't laugh when she returns an entire library in this room
09:48 AM synja: ;)
09:48 AM rue_house: this isn't playing out for me
09:48 AM rue_house: I want it as a state machine
09:48 AM synja: here
09:49 AM rue_house: a lut based, self modifying one
09:49 AM rue_house: alic1a, get lut based state machine in C
09:49 AM synja: alic1a, get code for named entity recognition in c
09:49 AM synja: this might work
09:49 AM synja: better results in python, i bet
09:51 AM synja: alic1a, get code for named entity recognition in python
09:51 AM alic1a: synja: >>> from nltk import ne_chunk, pos_tag, word_tokenize>>> from nltk.tree import Tree>>> >>> def get_continuous_chunks(text):... chunked = ne_chunk(pos_tag(word_tokenize(text)))... prev = None... continuous_chunk = []... current_chunk = []... for i in chunked:... if type(i) == Tree:... current_chunk.append(\
09:51 AM synja: ha rue_house
09:52 AM rue_house: hmm
09:52 AM rue_house: time to go to work, bye!
10:31 AM veverak: maybe someone here can give me a hint
10:31 AM veverak: https://cdn-learn.adafruit.com/assets/assets/000/031/354/original/adafruit_products_schem.png?1458433763
10:32 AM veverak: adafruit has interesting circuit to start the "programming mode" of esp
10:32 AM veverak: drawn right of the ESP
10:32 AM veverak: GPIO0/RESET have both PULLUPS
10:33 AM veverak: and RTS and DTR are connected to CP2104 uart BRIDGE
10:33 AM veverak: I am not sure I understand what does that circuit do
10:34 AM veverak: in theory, if one of RTS or DTR would be set to HIGH, it should powerup those PNP transistors should get current from from REST/GPIO0 into ... itself and interlock itself ?
10:35 AM veverak: it seems to me, like only way the current can flow than is either to RTS or DTR pin
02:58 PM Snert__ is now known as Snert
07:22 PM rue_house: veverak, it looks like their pulling either reset of gpi10 to the -10V of the rs232
07:25 PM rue_house: ooooh its not a real rs232 port
07:26 PM rue_house: so just to gound then
07:26 PM rue_house: but one has to be low
07:26 PM veverak: yeah
07:26 PM veverak: so one high, one low, does not matter which one
07:26 PM veverak: or both low ?
07:26 PM veverak: nah, I am confused with it
07:27 PM rue_house: two different situations
07:27 PM rue_house: only one can go low at a time
07:27 PM veverak: hmm
07:27 PM rue_house: dtr low and rts high makes gpio0 low
07:28 PM rue_house: rts low and dtr high maesk reset low
07:28 PM veverak: interesting
07:30 PM rue_house: aha
07:30 PM rue_house: whats that ID pin on the usb?
07:31 PM rue_house: is that for master/slave select?
07:31 PM rue_house: mm I need to make a circuit board
07:32 PM rue_house: anniepoo_, what makes work work
07:32 PM rue_house: I'v been thining about this
07:32 PM rue_house: cause somethign dosn't add up
07:51 PM Tom_L: well my remap code works
07:52 PM rue_house: doesit remap a human brain?
07:52 PM rue_house: I need a defreag
07:53 PM rue_house: degrag
07:53 PM rue_house: defrag
07:53 PM rue_house: yea that
08:00 PM rue_house: "your IN your web browser dude!" .. taps on the screen... "let me out..."
09:07 PM anniepoo_: my work's play
10:09 PM rue_house: heh
10:10 PM rue_house: AHA!
10:10 PM rue_house: AHAHAHAHAHA HAH!
10:11 PM rue_house: ok
10:11 PM rue_house: okok
10:11 PM rue_house: ok
10:11 PM rue_house: the LM431 CAN be used as a relaxation osc!
10:11 PM rue_house: THAT MEANS that pwm circuit I have can operate at 5V
10:12 PM rue_house: did you see the circuit?
10:12 PM rue_house: did ya?
10:12 PM rue_house: is anyone awake!?
10:12 PM rue_house: Did I forget that I'm alone on this rock?
10:12 PM rue_house: with just my imaginary friends...
10:13 PM rue_house: do it!
10:13 PM rue_house: yea, yes to it, do it now
10:14 PM rue_house: this means that the 3 transistor pwm circuit can be made of the parts of any old power supply
10:14 PM rue_house: but dude, the Tl494?
10:14 PM rue_house: no, shutup, sssh
10:14 PM rue_house: ok
10:46 PM Tom_L: rue_house, you are not alone
10:47 PM Tom_L: we are just watching you thru your glass box
10:48 PM Tom_L: rue_house, how well do you know python?
10:49 PM rue_shop3: the TL431 relaxation osc sucks compared to the pn2222 one
10:49 PM rue_shop3: I know enough python to be dangerous
10:49 PM rue_shop3: but I'm a monkey coder, all I need to know is the syntax
10:50 PM rue_shop3: no packages from china today, how much does that suck!?
10:51 PM orlock: Tom_L: i use it a bit
11:01 PM Tom_L: i'm not used to the oops style. i didn't grow up on oops
11:01 PM Tom_L: and i don't know how to find out what objects are available naturally
11:02 PM Tom_L: not sure it's a curve i want to go around
11:04 PM Tom_L: so changing 5 to 5.0 changes it from int to float?
11:10 PM rue_shop3: well, I think everything is a string till its used
11:11 PM rue_shop3: you trying to make a binary packet?
11:11 PM rue_shop3: knowing how to talk python is different from knowing how it works
11:11 PM Tom_L: not trying to do anything but get a small handle on the language
11:11 PM rue_shop3: its auto-type conversion to the yingyang
11:11 PM Tom_L: like c?
11:11 PM rue_shop3: no
11:12 PM rue_shop3: think of it as whatever you use it as
11:12 PM Tom_L: that's dangerous
11:12 PM rue_shop3: automatically dealt with as you use it
11:12 PM rue_shop3: yea
11:18 PM Tom_L: are there compatibility issues between versions?
11:25 PM Tom_L: rue_shop3, have you ever tried the windows version?
11:59 PM rue_mohr: 3 is totally different
