12:15 AM day_ is now known as daey
12:58 AM rue_bed2: LeoNerd, would you like a hand
01:32 AM Emil: LeoNerd: you should report it to upstream
01:32 AM Emil: LeoNerd: because those files still do not come with the latest source
01:34 AM Emil: https://emil.fi/toolchain
02:09 AM kilobyte_ch: Anyone any idea on how to calculate the AC Voltage/Level from an incoming AC Signal? Already sampling the Signal perfectly. But now I want the actual Level from this "raw" AC signal.
02:13 AM Emil: You mean Vpp?
02:14 AM Emil: Just track Vmax and Vmin
02:21 AM kilobyte_ch: Yes, Vpp would be what I need. I'm not quite sure on how to acomplish that. Technicaly I would need to constantly take the average Vmax and average Vmin, right?
02:25 AM Casper: Vpp is voltage peak to peak
02:26 AM Casper: for 120VAC it would be about 340V
02:27 AM Casper: 120VAC * 1.4142 = 169.70Vpeak, so Vpp = 2xVpeak = ~340V
02:27 AM Casper: if you want rms, then it get more complicated :D
02:29 AM daey: 1.4142 being sqrt(2)
02:30 AM Casper: and the inverse of 0.707 :D
02:30 AM kilobyte_ch: Sure, but I'm not quite sure on how to meassure Vpeak or Vmax/min
02:31 AM kilobyte_ch: (For a signal with no fixed frequency)
02:32 AM Casper: Vpeak Vmax/min have no relation to frequency
02:32 AM Casper: find the highest and lowest value in your signal
02:33 AM Casper: Vmax = 0; Vmin = 0, for each Vsample, if Vsample > Vmax then Vmax = Vsample; if Vsample < Vmin then Vmin = Vsample;
02:34 AM Casper: let it run for atleast 1 cycle, then read the Vmin and Vmax
02:34 AM Emil: And Vrms is 0.7*Vpp
02:35 AM Casper: Vrms = Vpeak * 0.707 or Vpeak / 1.4142
02:35 AM Casper: not Vpp
02:35 AM kilobyte_ch: But I have to reset Vmax/min at some point. Otherwise I would have just the highest Peak I had some time ago on the signal. But when?
02:35 AM Emil: Casper: ah yeah
02:35 AM kilobyte_ch: Should I e.g. just smaple 100 Samples and then find the max/min and that's it?
02:35 AM Emil: ...
02:35 AM Emil: kilobyte_ch:
02:35 AM Emil: can you not read?
02:36 AM Emil: You track Vmax and Vmin
02:36 AM Emil: So yes
02:36 AM Emil: You should low pass filter it for example
02:37 AM kilobyte_ch: That's exactly the Point, I actually have a "low pass" thing with a cumulating condenser to make this "operation" in hw. But I want/need to to it in SW.
02:37 AM kilobyte_ch: But will try the approach with x samples and tracking vmax/min from that. That was the knot in my thought.. :)
02:41 AM Emil: I would track a new Vmax and Vmin after every pass at the DC point
02:41 AM Emil: And low pass filter those Vmax and Vmin
02:44 AM kilobyte_ch: hmm, I don't have a really "defined" zero crossing point (Signal has a DC offset which is not the same on every device, depends on the actual settings on the device). So this isn't that easy to track.
02:45 AM kilobyte_ch: But the actual HW which does the job has a "low pass" function through the capacitor. So I think my "averiging" does a equivalent thing, but let's see how it performs.
02:46 AM Emil: That's why you track Vpp
02:46 AM Casper: Vpp / 2
02:46 AM Emil: I didn't say zero, I said DC
02:49 AM Emil: And update the lowpassed Vmax and Vmin at DC crossing
02:52 AM kilobyte_ch: And how should I track the DC Point/"Virtual zero crossing point"?
02:52 AM kilobyte_ch: Averiging the signal or what?
02:53 AM JanC is now known as Guest1067
02:53 AM JanC_ is now known as JanC
03:00 AM Emil: You track Vmin and Vmax
03:00 AM Emil: that's how
03:00 AM Emil: You can also just low pass the whole thing
03:00 AM Emil: But it takes a while to average out
03:01 AM _ami_: Emil, did you make self powered usb devices before? i wonder how usb device would know that its connected to host (since its already powered before) and start the usb_init() and other stuffs
03:01 AM Emil: And the moar you sample the stricter your low pass has to be
03:02 AM Emil: _ami_: hm?
03:02 AM Emil: Ah
03:04 AM Emil: _ami_: the host will signal
03:04 AM Emil: _ami_: usb is host driven (with some small exceptations)
03:04 AM _ami_: Emil, but usb_init is already called up before and device is doing while (1) {}
03:04 AM _ami_: in general, the device firmware code is like below
03:04 AM Emil: _ami_: when you insert your device the usb becomes aware and sets a reset condition on the line
03:05 AM Emil: s/usb/host
03:05 AM Emil: http://www.usbmadesimple.co.uk/ums_4.htm
03:05 AM Emil: When you plug a USB device in, the host becomes aware (because of the pullup resistor on one data line), that a device has been plugged in.
03:05 AM Emil: The host now signals a USB Reset to the device, in order that it should start in a known state at the end of the reset. In this state the device responds to the default address 0. Until the device has been reset the host prevents data from being sent downstream from the port. It will only reset one device at a time, so there is no danger of two devices responding to address 0.
03:05 AM _ami_: main() { .. usb_init(); .. while (1) { usb.loop(); } }
03:06 AM Emil: _ami_: I'm sorry Dave, I'm afraid you can't do that
03:07 AM Emil: Unless you ISR reset when USB tells you there's a reset
03:07 AM _ami_: Emil, how abt connect a gpio to VUSB and then i know when usb device is physically plugged in?
03:08 AM Emil: But why would you do that
03:08 AM Emil: IIrc the usb stack can tell you if there's usb reset
03:08 AM Emil: s/stack/peripheral/
03:08 AM _ami_: hmm..
03:08 AM Emil: we are talking about 32u4?
03:08 AM Emil: Or some arm
03:09 AM _ami_: arm basically.
03:09 AM _ami_: stm32s
03:10 AM Emil: https://emil.fi/jako/kuvat/2017-07-05_10-40-09_Kvk6QoY5.png
03:10 AM Emil: https://emil.fi/jako/kuvat/2017-07-05_10-40-20_StMXiWk8.png
03:11 AM Emil: https://emil.fi/jako/kuvat/2017-07-05_10-40-31_JEduYLz5.png
03:11 AM Emil: Similar will be available on your Arm
03:13 AM Emil: https://emil.fi/jako/kuvat/2017-07-05_10-42-29_MOJJbkWG.png
03:13 AM Emil: And so on
03:38 AM abc123: Hii cananyone help me with how to program avr chip with Attiny841
03:40 AM _ami_: Emil, thanks Emil. i will check further.
03:42 AM abc123: i am using usbasp programmer , it got detected but if i program it is showing like "unable to connect STK500"
03:43 AM Emil: Check your wiring
03:44 AM abc123: checked but i got doubt bcoz i am using 10 pin connector ,but i have kept only 5 pin to program ...is that ok?
03:46 AM Emil: https://www.ve7xen.com/blog/2014/03/07/programming-the-attiny841-with-avrdude/
03:47 AM Emil: http://captainunlikely.com/blog/2014/01/03/notes-on-the-attiny-841/
03:50 AM Emil: Anyone know i the 328p has a selectable gain or ADC?
03:50 AM abc123: Emil can you send me usbasp pinout description?
03:51 AM Emil: abc123: I'm sure you can find it if you use a search engine
03:54 AM abc123: emil thank u :)
03:54 AM abc123: am using atmel studio 7 will that be compatible for attiny841??
03:55 AM Emil: probably
04:02 AM Arek is now known as Guest62931
05:47 AM abc123: Hii ....first i gave wiring between usbasp and attiny wrongly ...but now i have corrected still while programming through amel studio7 same problem continues!!
05:47 AM abc123: can anyone help me to short it out
05:49 AM Emil: Check your wiring
05:49 AM Emil: And the articles I linked above
06:00 AM abc123: Reset must be given mandatorily?? ....bcoz am not getting reset pin continuity
06:00 AM Emil: reset must always be there
06:00 AM Emil: Dug
06:00 AM Emil: duh*
06:15 AM Gerritjan: i have a question i have a 17 dof human robot but now i need a header for it but i can only find the 16 pwm channels what can i do
06:16 AM Gerritjan: 16 channel servo pwm
06:18 AM Emil: hm?
06:18 AM Emil: Buy a pwm controller?
06:18 AM Emil: or do it in software
06:18 AM Emil: or add moar avr
06:18 AM Lambda_Aurigae: one attiny per servo.
06:18 AM Lambda_Aurigae: put them all on an i2c bus
06:19 AM Emil: :D
06:19 AM Gerritjan: well the pwm controller that i can find is like 16 channels
06:19 AM Lambda_Aurigae: and one main controller for them all.
06:19 AM Emil: Gerritjan: well, then use pwm from your avr
06:19 AM Emil: for the last one
06:19 AM Gerritjan: oke thats a option but cant i stack the pwm headers?
06:20 AM Emil: hm?
06:20 AM Emil: Stack?
06:20 AM Gerritjan: yea like 2 boards
06:21 AM Emil: Depending on the interace of coures you can use multiple pwm things
06:22 AM LeoNerd: But really; AVR chips usually have a number of PWM channels in them anyway - surely you've got at least one 16bit channel spare somehow
06:22 AM LeoNerd: If it's a 328P they're on PB1 and PB2, which shouldn't clash with I²C or SPI needed to talk to the external PWM controller
06:24 AM Gerritjan: oke, im asking that because im gone add some hands with 5 servo each hand to it so i need 12 pwm more because the wrist must also be a servo
06:24 AM LeoNerd: Ah, well if you need a lot more then yes, two controllers. Hopefully they're selectable somehow - I²C address settings, or SS lines for SPI
06:25 AM Gerritjan: i hope so to, i need to sort the Amperage to :S its like 11A for 17 servo`s
06:25 AM Emil: nice
06:26 AM Gerritjan: its to high :S
06:27 AM LeoNerd: The current to drive the motors doesn't have to come from the same place as the control signal
06:27 AM Lambda_Aurigae: "too"
06:28 AM Gerritjan: i know but still 11A
06:28 AM Lambda_Aurigae: some hefty servos.
06:29 AM LeoNerd: If it's 17 + 12, that's 29 motors.. 11A between them is not *all* that much each
06:30 AM Gerritjan: no thats the 17 only
06:31 AM Lambda_Aurigae: how is this robot powered?
06:31 AM Lambda_Aurigae: and what pwm controller are you looking at using?
06:33 AM Gerritjan: well the power i dont have any clue yet and the controller is from adafruit
06:34 AM LeoNerd: Oh well if it's only 17, then I'd suggest using one or two of the 16bit PWM channels on an AVR, in addition to that 16way controller
06:34 AM LeoNerd: No need to get two external controllers just for one more channel
06:34 AM Gerritjan: i know but i want to be safe for the hands that i have enough chanels
06:37 AM Lambda_Aurigae: https://www.adafruit.com/product/815
06:37 AM Lambda_Aurigae: this one?
06:37 AM Lambda_Aurigae: it is i2c interfaced so you can put multiples on a single i2c bus with different addresses.
06:40 AM Lambda_Aurigae: interestingly, the page says nothing about how much current it can handle delivering to the motors.
06:40 AM Gerritjan: yea thats a nice 1 :D and i can add more of the interfaces
06:41 AM LeoNerd: Oh, it's a 9685. I have loads of those
06:41 AM LeoNerd: The *drive* current to the motors doesn't pass through the chip, it's just a PCB track
06:41 AM LeoNerd: So whatever that track can carry. I expect it's quite a thick track
06:42 AM Gerritjan: oke :D
06:43 AM Lambda_Aurigae: it is a thick track, yes.
06:43 AM Gerritjan: Well i have a Nucleo board STM32F446 so it can handle alot :D
06:43 AM Lambda_Aurigae: note that with hobby servos, they don't draw current constantly unless they are moving or holding position against some torque.
06:44 AM Gerritjan: oke well its the MG996R servo
06:44 AM Lambda_Aurigae: I do recommend adding the big cap to the board though if you are going to be running servos on it...they will draw a lot of impulse current which can cause the chip to glitch if your power source can't handle the heavy draw all at once.
06:46 AM Gerritjan: yea but its using with walking like 3 servo`s and the rest its holding in position
06:47 AM Lambda_Aurigae: again, how are you planning on powering it? will it be tethered to a power source or be carrying a battery?
06:47 AM Gerritjan: no battery
06:48 AM Gerritjan: because it drains to quick
06:48 AM Lambda_Aurigae: so, tethered.
06:48 AM Lambda_Aurigae: you will need something that can provide 15A at 5V.
06:48 AM Lambda_Aurigae: that's going to be a hefty power cable too.
06:49 AM Lambda_Aurigae: I suspect that you will not be drawing the full 11A hardly at all though so could likely get away with 10A at 5V but to be on the safe side 50% over.
06:50 AM Lambda_Aurigae: my standard is, figure out how much you need and multiply that by 1.5.
06:50 AM Lambda_Aurigae: so you won't be powering that with a phone charger.
06:51 AM LeoNerd: 15A at 5V is getting into "remote sense" territory
06:51 AM LeoNerd: I'd be considering having a secondary "sense" pair along with the main current carrying copper and using a remote-able power supply
06:52 AM Gerritjan: Running Current 500mA - 900mA (6V), Stall Current 2.5A(6v)
06:53 AM Lambda_Aurigae: 15A at 5V is 75watt so, you won't be using a modded atx power supply for that most likely.
06:53 AM Gerritjan: But stall Current means that alsways 2.5A on the Servo/.
06:54 AM Gerritjan: servo?*
06:54 AM LeoNerd: How about just not starting all 17 servos at the same time? ;)
06:54 AM Lambda_Aurigae: that means if you hold the servo physically and don't let it turn then try to make it run electrically it is stalled.
06:55 AM Gerritjan: so it starts with 2.5A but uses like 600mA for turning
06:56 AM Lambda_Aurigae: starts with 2.5A?
06:56 AM Lambda_Aurigae: that's the max it will draw, not the start current.
06:57 AM Gerritjan: ahh so i need like 900mA * 17 and thats max it will pull
06:57 AM Lambda_Aurigae: tell it to hold center position, put a wrench on the output shaft and try to turn it away from that center position and it will go up to 2.5A max.
06:57 AM Lambda_Aurigae: I doubt anything on that robot will force those servos to max current.
06:58 AM Lambda_Aurigae: not sure where you got 11A though...if you go 17 servos by their stall current of 2.5A you get 42.5A
06:58 AM Gerritjan: 500 ma
06:58 AM Lambda_Aurigae: 15A at the 900mA run current.
06:59 AM Lambda_Aurigae: so my guestimate of 15A was pretty close on....with that information I would even go to 20A if you plan on running all the servos constantly.
07:00 AM Gerritjan: oke thats alot
07:01 AM Lambda_Aurigae: without some more details on the bot it's hard to guestimate any kind of current draw...do the servos all need to be powered to hold or will their normal non-activated hold torque be enough?
07:06 AM Gerritjan: dont know i need to find out on my own
07:07 AM Lambda_Aurigae: get a good high end 500W atx power supply and mod it for bench supply operation...SHOULD give you enough 5V current for that.
07:07 AM Gerritjan: https://www.aliexpress.com/item/1set-17DOF-Biped-Robot-Educational-Robot-Kit-17-Degrees-Of-Freedom-Humanoid-Humanoids-Walking-feet-Servo/1531579864.html?spm=2114.search0306.4.2.e9kSod
07:07 AM Gerritjan: this iit the bot
09:07 AM rue_house: interesting, those are usually $1000
09:07 AM rue_house: maybe its cause they usually use serial servos
09:08 AM rue_house: ooooh no servos
09:08 AM rue_house: its openpino!
09:09 AM rue_house: thats a lot for just the brackets
09:09 AM rue_house: I really meant to design a 3d printable version of openpino
09:09 AM rue_house: seeing as I have the no-longer-existant design files for it (weren't available last I looked)
12:31 PM Lambda_Aurigae: rue_house, would be fun to make something like that and sell it.
02:04 PM osteri1 is now known as osteri
02:06 PM Emil: Finaaalllyy
02:06 PM Emil: I have it working
02:06 PM Emil: ESP8266 TLS
02:06 PM Emil: with acceptable cipher
02:07 PM Emil: http://randomc.net/image/Boku%20no%20Hero%20Academia/Boku%20no%20Hero%20Academia%20-%2006%20-%20Large%2009.jpg
02:07 PM Emil: How I feel right now
02:07 PM Emil: Took some fucking perseverance
02:07 PM Emil: I tell you
02:08 PM xentrac: congratulations!
02:08 PM xentrac: what were the obstacles?
02:09 PM Emil: xentrac: Mostly nginx being fucking php
02:10 PM Emil: So
02:10 PM Emil: If esp doesn't send SNI
02:10 PM Emil: Nginx just takes some cert when you get a request to a port with multiple vhosts
02:10 PM Emil: it doesn't bail
02:10 PM Emil: it doesn't tell you
02:11 PM Emil: it just takes some
02:11 PM Emil: and since I have multiple vhosts (different domains)
02:11 PM Emil: it fails
02:11 PM Emil: and of course this shit arduino lib doesn't tell you that there's cert problems
02:11 PM Emil: I also had to edit my cipher suites to include AES256-SHA
02:14 PM xentrac: does "php" here mean "shitty"?
02:28 PM Emil: xentrac: it means trying too hard not to fail
02:28 PM Emil: It means doing shit because "lol lets" instead of sticking to what the programmer says
02:29 PM xentrac: haha
02:30 PM polprog: lol, it's like the recent java discussion ,there are some applications (even in web world) where php just doesn't.
02:31 PM polprog: and the ardweeny library probably wasnt great either
02:31 PM polprog: it's for blinking a led with your phone not for making aes ncryption xD
03:26 PM julius: hi
03:27 PM julius: i got a coding question to simplify my code, in here: https://bpaste.net/show/8813d058916b on line 22 i define a function to blink a led "normal", and below that i create the same functionality just changing the speed
03:28 PM julius: what i would like to have is a function that accepts LED_1, LED_2..... and a speed
03:28 PM julius: so i dont have to rewrite the same code everytime, but i dont know how to give a function the information which LED to turn on
03:39 PM Emil: eh?
03:40 PM Emil: You dont know how to pass values?
03:40 PM Emil: or addresses?
03:40 PM julius: values i can pass
03:40 PM julius: and pointers also
03:40 PM Emil: wellthen
03:41 PM Emil: pass them?
03:41 PM julius: i coded that before but got stuck...let me retry
03:46 PM Emil: if you dont pass a one to one physical mapping then you have to if else or switch case
03:46 PM Emil: or math it
03:50 PM noHitW_work: that count isnt the speed, its how long
03:59 PM julius: its how many times the led should flash
03:59 PM julius: almost got it
04:04 PM julius: ok, im gonna sleep on the hunk of errors make presents me with :)
04:05 PM xentrac: what is the first error?
04:05 PM julius: the first tells me that im to lazy
04:05 PM julius: gonna do that tomorrow
04:45 PM mrrobot_: hi, i have to implement USB on chip ATxmega128A4U. I have never implemented USB so i seek any advice or guidance.
04:46 PM Emil: How many tears are you willing to sacrifice to the dark gods?
04:46 PM mrrobot_: ??
04:47 PM Emil: yes
04:47 PM Emil: that said, "usb made simple" should be a good start
04:49 PM mrrobot_: i dont know where to begin.
04:50 PM Emil: Try using your favourite search engine with that "usb made simple"
05:01 PM mrrobot_: thank you.
05:05 PM mrrobot_: Emil:do you know where i could find a lib or something for USB ?
05:06 PM Emil: mrrobot_: lua
05:06 PM Emil: lufa*
05:10 PM mrrobot_: u saved me :)
05:11 PM Emil: np
05:33 PM dan3wik is now known as dan2wik
06:15 PM Emil: Hot damn these v2s look nice
06:35 PM Jartza: haha
06:35 PM Jartza: I got this 28" 4k monitor
06:35 PM Jartza: and 6€ vga->hdmi converter
06:35 PM Jartza: I just had to try
06:35 PM Jartza: seems octapentaveega runs just nicely on it, lol
06:36 PM Emil: lol
06:37 PM twnqx`: i used a c64 with a full hd projector before
06:37 PM twnqx`: works.
06:37 PM Emil: What I want though is a spi controlled frame buffer with displayport output
06:38 PM Emil: And some commands like "set resolution, empty, copy, so on buffer
06:39 PM Jartza: twnqx`: yeah, I just wasn't sure how well this chinese converter understands what my octapentaveega outputs
06:40 PM Lambda_Aurigae: Jartza, I've connected mine to my projector..15foot diagonal screen.
06:40 PM Jartza: at least c64 outputs standard composite & s-video
06:40 PM enhering: please spread the word: https://www.indiegogo.com/projects/wilhelm-reich-documentary-final-post-production-film-history#/
06:40 PM Jartza: Lambda_Aurigae: nice :)
06:41 PM Lambda_Aurigae: currently it's connected to a 14 inch vga ELO touchscren with serial port touchscreen interface.
06:42 PM Lambda_Aurigae: plan is to reverse engineer the serial touch interface and make a touchscreen button controller interface.
06:42 PM Lambda_Aurigae: for KSP
06:43 PM Emil: enhering: what's that
06:43 PM Emil: Lambda_Aurigae: niiiiceee
06:45 PM Jartza: Lambda_Aurigae: whoa :)
06:45 PM enhering: A documentary on wilhelm reich
06:45 PM enhering: needs funding
06:45 PM enhering: very important.
06:47 PM Lambda_Aurigae: using a pic32 for the interface/controller system.
06:51 PM Lambda_Aurigae: so, just watched some of the HALO movies...in them one of the main characters is an AI that starts out good, but with good intentions, turns evil and tries to take over the galaxy with an attitude of, "I know what is best for you so do as I say and be good or I will destroy you."
06:51 PM Lambda_Aurigae: HALO being a creation of microsoft.
06:51 PM Lambda_Aurigae: the AI character in question is named,,, Cortana.
06:57 PM Lambda_Aurigae: Windows 10, Cortana search system...hmmmm.
07:00 PM Lambda_Aurigae: Cortana starts out as a mild mannered nice hot AI goodie goodie and ends up a royal wanna kill everybody bitch.
07:02 PM Emil: Lambda_Aurigae: ooh
07:02 PM Emil: a master collection of all cutscenes and things
07:04 PM Lambda_Aurigae: yeah.
07:04 PM Lambda_Aurigae: with gameplay mixed in to fill the gaps.
07:04 PM Emil: I have been thinking about buying a new xbox
07:05 PM Lambda_Aurigae: I have never owned one.
07:05 PM Lambda_Aurigae: won't pay for anything from microsoft myself.
07:05 PM Emil: and just mashing through the all dem campaigns
07:05 PM Emil: Dem memories
07:05 PM Emil: I still remembed vividly when we beat Halo 1
07:05 PM Lambda_Aurigae: did find some cheat codes for the PC versions of the game..
07:05 PM Emil: We started when I was 8
07:05 PM Emil: and Finished when I was like 9
07:05 PM Lambda_Aurigae: kids...
07:05 PM Lambda_Aurigae: my first video game was pong,,,when I was,,,12 or so.
07:06 PM Emil: I didn't understand enough English :D
07:06 PM Emil: But then on third or beginning of fourth I understood
07:06 PM Lambda_Aurigae: had 2 modes...one player up and down and two player across the screen.
07:06 PM Emil: and it just fucking clicked
07:07 PM Lambda_Aurigae: our controllers didn't even have buttons...just a knob.
07:07 PM Lambda_Aurigae: [:
07:07 PM Emil: The Original Xbox
07:07 PM Emil: that was one awesome thing
07:07 PM Lambda_Aurigae: something like that.
07:07 PM Vexer: The original Xbox was a fantastic device.
07:07 PM Lambda_Aurigae: might have to make a pong game with the OPV now.
07:07 PM Jartza: ooh
07:07 PM Jartza: T-40 sec
07:08 PM Lambda_Aurigae: ?
07:08 PM Jartza: spacex
07:08 PM Jartza: https://www.youtube.com/watch?v=MIHVPCj25Z0
07:08 PM Lambda_Aurigae: didn't know they were going today.
07:08 PM Jartza: it was cancelled few times
07:09 PM Lambda_Aurigae: yeah..
07:09 PM Lambda_Aurigae: thought they missed their window.
07:09 PM Emil: https://emil.fi/jako/kuvat/2017-07-06_02-38-45_wFx97LTs.png
07:09 PM Emil: These are images that will be on history books
07:10 PM Emil: Max pressure overcame
07:10 PM Emil: cool cruising from now on
07:11 PM Lambda_Aurigae: ksp has a much nicer chase camera.
07:11 PM Vexer: Pretty cool stuff going on.
07:12 PM Lambda_Aurigae: yeah.
07:13 PM Lambda_Aurigae: haven't been able to find any info though...is this a new rocket or a refurb?
07:14 PM Lambda_Aurigae: guessing new due to the cost and sensitivity of the payload.
07:14 PM Emil: Aww
07:14 PM Emil: no landing
07:14 PM Jartza: well, first stage was not recoverable :(
07:14 PM Emil: booo
07:14 PM Jartza: that's always the most intense part, following the landing
07:15 PM Lambda_Aurigae: yeah...due to the flight no recovery of first stage.
07:15 PM Lambda_Aurigae: payload too heavy and going to geosync orbit.
07:16 PM Lambda_Aurigae: they are getting some video signal degredation though.
07:16 PM Emil: Well no wonder
07:17 PM Lambda_Aurigae: or maybe just some reflectivity issues on that one camera.
07:17 PM Emil: Going against the horizon
07:17 PM Emil: There's still limits to how much power you can put and can put out
07:17 PM Emil: And tracking live video from multiple locations is expensive
07:18 PM Emil: Well
07:18 PM Emil: Good night
07:20 PM Lambda_Aurigae: spaceX needs to put up a bunch of relay sats for video relay and tracking!
07:21 PM Emil: That's one goal
07:21 PM Emil: Personal satellite constellation
07:22 PM Emil: But yeah
07:22 PM Emil: Good night
07:37 PM Jartza: whoa. speed almost at the red line
07:38 PM Jartza: hope they are not speeding
