01:02 AM rue_bed: compile number.... 6?
01:05 AM rue_bed: think I know how to manage the ramdisk
01:05 AM orlock: rue
01:05 AM rue_bed: yea
01:05 AM rue_bed: I would be nice to have somting that autoconfiured akernel basedon detected hardware
01:05 AM orlock: that fucking ESP code
01:05 AM orlock: well, the code is fine
01:05 AM alic1a: orlock: What did you mean by that?
01:05 AM rue_bed: esp?
01:05 AM rue_bed: 8266?
01:05 AM orlock: alic1a: do dying bots see a fading LED at the end of the tunnel?
01:05 AM rue_bed: is it messed up?
01:05 AM alic1a: orlock: Nevermind...
01:05 AM rue_bed: orlock, 8266?
01:05 AM orlock: yeah
01:05 AM rue_bed: k
01:05 AM rue_bed: bad arduino libraries?
01:05 AM orlock: I've been doing most of my prototyping on a NodeMCU board
01:05 AM orlock: nope
01:06 AM rue_bed: k
01:06 AM rue_bed: sounds like the cheap one I got
01:06 AM orlock: and then, doing more functional testing with another board, same type of ESP chip, same arduino target
01:06 AM rue_bed: k
01:07 AM orlock: so testing on one of these https://frightanic.com/iot/comparison-of-esp8266-nodemcu-development-boards/ and more functional testing on one of these:
01:07 AM orlock: http://www.icstation.com/esp8266-serial-wifi-witty-cloud-development-board-module-mini-nodemcu-p-8154.html
01:07 AM orlock: Same arduino target, same code.
01:07 AM alic1a: orlock: I don't know what you meant by that
01:07 AM rue_bed: did ou work out the udp bug??
01:07 AM orlock: Blaming the board.
01:08 AM orlock: I can swap between the two, data i see on the first board is fine
01:08 AM tsquar3d: Hey all -- odd question here -- is such a thing as "degree of situational awareness" when it comes to robots?
01:08 AM orlock: second board sends bogus data packets.
01:08 AM alic1a: tsquar3d: Situational awareness or situation awareness (sa) is the perception of environmental elements and events with respect to time or space, the comprehension of their meaning, and the projection of their status after some variable has changed, such as time, or some other variable, such as a predetermined event
01:08 AM orlock: It's a valid UDP IP packet to the right port, but the actual data is usually 000000
01:09 AM orlock: tsquar3d: I'm hoping to make one that doesnt fall off a ledge?
01:09 AM orlock: tsquar3d: and theres self-driving cars that can avoid walls
01:09 AM orlock: rue: anyway, it was NOT a bug i was expecting to see manifest like that
01:10 AM tsquar3d: orlock: Exactly... like, is there some sort of quantitative measure or convention used to describe a machine's degree of situational awareness.
01:10 AM orlock: unsure, sounds like philosphy
01:10 AM tsquar3d: orlock: I am trying to find some papers on it... but I keep turning up mostly developmental psych papers.
01:11 AM tsquar3d: orlock: yeah -- I suppose it does.
01:13 AM tsquar3d: orlock: I found a paper that I think may work.
04:03 AM Jak_o_Shadows: most kalman filters will give you an error estimate?
04:03 AM Jak_o_Shadows: or like, to use one effectively you get taht anyway

12:16 PM SpeedEvil: teeny linear actuators
12:29 PM deshipu: SpeedEvil: yeah, if you can drive them
12:39 PM SpeedEvil: they're just two phase steppers
12:40 PM deshipu: right, so you need a driver, which will be larger than themselves
01:58 PM SpeedEvil: logic chips are plausible drivers, at that power level
02:08 PM deshipu: at what power level?
02:08 PM alic1a: deshipu: Your Power number is equally as important as your level, and it's something you'll have to keep in mind from the very beginning.
02:15 PM SpeedEvil: deshipu: it's a 3.3mm diameter stepper, I would be moderately surprised if it wanted more than 20mA

08:59 PM rue_: I have X!
08:59 PM rue_: be it a bit ... disjointed
09:00 PM Tom_itx: yay!
09:00 PM Tom_itx: perfect match
09:00 PM rue_: so, the new kernel decided that it would boot on the other video card that at the time I couldn't get working
09:00 PM rue_: which was interesting
09:01 PM Tom_itx: is ^^ this rue undecided?
09:01 PM alic1a: Tom_itx: Theyhaveto havewateran' lots of it, too, an' th' nearest of any account is th' Pecos,orsomeof them streams over in th' Panhandle.
09:01 PM Tom_itx: shop, bed, house, shop2 3 4
09:01 PM alic1a: Tom_itx: What other kinds of buildings you do not like?
09:01 PM rue_: "hexchat" did not import "xchat"s profile properly
09:02 PM rue_: I have some tuning to be done
09:02 PM Tom_itx: alic1a wtf are you talking about?
09:02 PM Tom_itx: rue is that a bot?
09:02 PM rue_: yes
09:02 PM Tom_itx: who owns it?
09:02 PM rue_: not one of mine
09:02 PM synja: she gets confused sometimes
09:02 PM Tom_itx: yours?
09:02 PM rue_: a bit on the verbose side
09:03 PM synja: she doesn't look for user names in messages
09:03 PM Tom_itx: did you check to make sure it was a she?
09:03 PM synja: she doesn't have a dongle, if that's what you mean
09:04 PM Tom_itx: so what did i say that tripped her trigger?
09:08 PM synja: you were asking a question, but it was about a user
09:08 PM synja: i'll note that
09:22 PM rue_: arg, I'm getting all the join and parts too
09:33 PM rue_: :) 6 packages from china today
09:34 PM rue_: I got the W5500 board, have to play with that
10:39 PM rue_: I'm gonna be putting my machine back to the way I like it for weeks
10:42 PM Tom_itx: maybe your likes can change along the way too
10:43 PM rue_: NO! I'M OLD AND I KNOW THE WAY I LIKE IT!!
10:43 PM rue_: :)
10:43 PM alic1a: rue_: So</a>, now I know the ethernet shield works, but the logic levels are a little 'off'.
10:43 PM Tom_itx: old... pfft
10:43 PM rue_: alic1a, who said that
10:43 PM alic1a: rue_: I can not remember who said it.
10:43 PM rue_: damnit alic1a get a brain
10:44 PM alic1a: rue_: Why do not you like neural structures. Would you say that to their face?
10:44 PM Tom_itx: wtf trips her trigger?
10:44 PM synja: lmao
10:44 PM rue_: biab, maybe,
10:44 PM synja: Tom_itx, she's always listening and responding. she only talks when she wants something
