01:47 AM drekipus: damn fellas
01:50 AM drekipus: who was the one that used python twisted for his processing of tcp data?
01:50 AM rue_shop3: dont remember what I used what for
01:55 AM Jak_o_Shadows: I said I had once. But I lost that code
01:55 AM Jak_o_Shadows: Lately i've just used threads.
01:55 AM Jak_o_Shadows: Mostly in the motto of getting the most recent data asap
05:10 AM pokmo: anyone know of any magnetometer that has a 'wake on motion' equivalent?
05:10 AM pokmo: it seems only accelerometers can wake on motion
05:25 AM Jak_o_Shadows: You want this for poewr conservation reasons?
05:35 AM pokmo: Jak_o_Shadows, yeah
05:36 AM Jak_o_Shadows: Is it like, possible, in a physics sense?
05:36 AM pokmo: just want it and the MCU to wake up when it moves
05:36 AM Jak_o_Shadows: Like an acceleromoter has a MEMS, and that may give you a nice wake up signal
05:36 AM pokmo: wake on magnetic field changes?
05:36 AM Jak_o_Shadows: the magnetic field may change even when your object doesn't move?
05:37 AM pokmo: sure. that's fine with me
05:38 AM pokmo: but, am i right that accelerometers wake on motion because of the physical impact?
05:38 AM pokmo: the physical impact causes the MEMS to deform
05:39 AM pokmo: but by the same logic, could a change in the magnetic field somehow wake up a magnetometer then?
06:00 AM polprog: if it's a hall effect magnetometer then you would need to use some tiny microcontroller which reads the readings and sends a signal if it's digital or a simple analog comparator with hysteresis that sends the wake signal
06:06 AM pokmo: polprog, but the current draw when it's in 'measurement mode' isn't low
06:07 AM pokmo: for instance, the HMC5883 is 100uA https://cdn-shop.adafruit.com/datasheets/HMC5883L_3-Axis_Digital_Compass_IC.pdf
09:20 AM xxoxx: hi
09:20 AM xxoxx: c3po is gay
12:10 PM deshipu: didn't know robots had sexual preferences
12:10 PM deshipu: what about the k2so?
12:19 PM xxoxx: r2d2 has lisp
12:28 PM rue_house: I'v not heard of gay, is it like C?
12:31 PM xxoxx: means happy
01:07 PM Tom_L: rue_house
01:20 PM rue_house: yes?
01:22 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/mushroom.jpg
01:22 PM Tom_L: ever see one of those?
01:22 PM rue_house: no
01:22 PM Tom_L: me either until this year
01:22 PM polprog: nice mushroom
01:22 PM polprog: i found some this year too. chanterelles mainly
01:23 PM Tom_L: dunno what it is
01:23 PM Tom_L: do you?
01:23 PM polprog: no idea
01:23 PM polprog: none of those i know
01:25 PM rue_house: Tom_L,
01:26 PM rue_house: http://ruemohr.org/~ircjunk/images/mushroom.jpg
01:26 PM rue_house: ever seen one of those?
01:26 PM Tom_L: not around here
01:27 PM rue_house: me either till this year
01:27 PM Tom_L: the white one in the back yes
01:27 PM Tom_L: typically in nature, if it's pretty, it's deadly
01:28 PM rue_house: those were growing at the hospital
01:28 PM Tom_L: good place for them if you decide to eat one
01:28 PM rue_house: infront of the mental health tho, about 150' from addictions
01:28 PM Tom_L: how fitting :)
01:29 PM weyland|yutani: Tom_L, maybe they grow only near dead people?
01:29 PM Tom_L: i don't eat them unless they come on a pizza
01:35 PM Tom_L: https://en.wikipedia.org/wiki/List_of_deadly_fungus_species#/media/File:Amanita_muscaria_3_vliegenzwammen_op_rij.jpg
01:35 PM Tom_L: https://en.wikipedia.org/wiki/List_of_deadly_fungus_species
01:35 PM SpeedEvil: Tom_L: missing brewers yeast.
01:37 PM Tom_L: http://mushroomobserver.org/image/show_image/770153?obs=285823&q=80ZT
01:37 PM Tom_L: can't tell if that's the one i have or not
01:37 PM weyland|yutani: https://www.youtube.com/watch?v=uloBD9xxwZ0
01:37 PM rue_house: M is for mushroom
04:53 PM rue_shop3: ok, I have a working esp8266
05:35 PM drekipus: who was the one who had the time slicing TCP here with python twisted?
09:45 PM drekipus: GUYS I WANT TO REEEEEE
09:45 PM drekipus: why don't we have a channel bot in here?
10:02 PM Jak_o_Shadows: Bought the IRLZ44N's. Did the calcs and the 640N's wren't gonna work. Shame, cause it's one more thing that might not arrive before christmas
10:30 PM rue_shop3: drekipus, do you know when?
10:30 PM rue_shop3: Jak_o_Shadows, 640 is a horrid fet
10:31 PM Jak_o_Shadows: I have noticed :P
10:51 PM drekipus: oh maybe it was Jak_o_Shadows. but lost his code
