[16:48] <SpacenearUS> New position from 03KF7RCV-11 after 033 days silence - 12http://tracker.habhub.org/#!qm=All&q=KF7RCV-11
[16:51] <Laurenceb_> yeah but in a simple case of fuel exhaustion the engine would have shut down
[16:52] <SpeedEvil> It could have been attempting to minimise impact velocity
[16:52] Action: SpeedEvil tries to find
[16:53] <lz1dev> Laurenceb_: depends on the trust
[16:54] <SpeedEvil> Laurenceb_: you mean the partial video that does not show the landing?
[16:54] <Laurenceb_> yeah I wondering if it went into some sort of failsafe mode where it throttles to minimum and tried to steer away from the barge
[16:54] <Laurenceb_> yeah
[16:54] <SpeedEvil> ah
[16:54] <SpeedEvil> Or it was saving fuel and going to ignite all nine engines to minimise gravity losses
[16:54] <Laurenceb_> I read that they tried igniting three engines for landing
[16:55] <Laurenceb_> surely they must have planned to shut down two at some point
[16:55] <SpeedEvil> I think that's a misreading
[16:55] <Laurenceb_> ah
[16:55] <SpeedEvil> the boostback burn would normally use three
[16:55] <Laurenceb_> maybe there are details hiding in the FAA documentation
[16:55] <SpeedEvil> using three for the entry burn is not very surprising
[16:55] <Laurenceb_> I remember reading that the grid fins direct it slightly off target
[16:56] <SpeedEvil> In principle, you could gain a little heading up to max q
[16:56] <SpeedEvil> A lot of this is leaks from possibly very earlier days
[16:56] <Laurenceb_> so if the engine fails to ignite for the landing burn it causes less damage

[16:56] <SpeedEvil> It can actually manage to land on an outside engine if I've done the maths right
[16:57] <SpeedEvil> But it's unlikely to have the code for that
[16:57] <SpeedEvil> (assuming everything else goes a bit righter)
[16:57] <Laurenceb_> for the return to landing site its supposed to crash on the beach if engine ignition fails
[16:57] <Laurenceb_> as that puts it further away from important facilities and people
[16:58] <Laurenceb_> at Vandenburg they planned to have it crash in a nature reserve
[16:58] <Laurenceb_> that didnt go down well
[17:01] <R34lB0rg> that was the reason KSC was built where it stands today

[19:35] <garymortimer> Sunday night is always best shared with 0x6C9CCC
[19:35] <fsphil> that works out to 434.449
[19:36] <garymortimer> Thanks very much, without making my head hurt how did you get to that.....
[19:36] <fsphil> I recently read the datasheet so had it in my notes
[19:36] <fsphil> 434250000 / (32000000 / (2 ^ 19)) = 0x6C9000
[19:37] <fsphil> the 32mhz is the clock on the rfm module
[19:38] <fsphil> 2 ^ 19 is the divider, which annoyingly gives a 61.03515625 rather than a nice integer

[19:48] <Lunar_Lander> microwaves are interesting
[19:48] <fsphil> indeed
[19:48] <Lunar_Lander> you can interact with electron spins
[19:48] <Lunar_Lander> :)
[19:49] <SpeedEvil> And heat bacon
[19:50] <Lunar_Lander> yea :)
[19:50] <fsphil> heats our food, gives us internet. what more could you want
[19:50] <SpeedEvil> I haven't seen any consumer gear out - but NXP is pushing transistors for microwaves now.
[19:50] <Lunar_Lander> yeah

[22:53] <fsphil> hiya DL7AD. why no colour? :)
[23:03] <DL7AD> fsphil: i encode the image into JPEG while im sampling the image.
[23:03] <DL7AD> because i dont have enough memory to store a raw image into the memory
[23:03] <DL7AD> i can do this for QVGA
[23:04] <DL7AD> but the JPEG-encoding is too slow to archieve color-VGA
[23:04] <DL7AD> so i left the color components
[23:05] <DL7AD> fsphil: i still use the OV9655
[23:05] <DL7AD> i did not manage to implement the OV2640 yet
[23:05] <DL7AD> fsphil: but unfortunately SSDV doesnt allow 1 component encoding
[23:06] <Lunar_Lander> you now got picture transmission?
[23:06] <DL7AD> Lunar_Lander: yes already for some time
[23:06] <Lunar_Lander> nice :)
[23:07] <fsphil> you can skip colour and just output a 0 DC and no AC coefficients for the colour channels
[23:07] <fsphil> you'll probably have to tweak your jpeg encoder
[23:08] <fsphil> or try and optimise the encoder. colour is important :)

[23:11] <DL7AD> fsphil: i am already using a microcontroller algorithm
[23:11] <DL7AD> fsphil: do you have a better algorithm?
[23:11] <DL7AD> im currently using JPEG ant
[23:12] <Laurenceb_> http://amazingdiyprojects.com/pdf/edf_microafterburner.pdf
[23:12] <Laurenceb_> this would be good for a hot air ballute test vehicle
[23:13] <SpeedEvil> Oh - neat
[23:13] <SpeedEvil> I'd wondered about that but never really thought on it.
[23:13] <SpeedEvil> Clearly it'll be shit compared to proper jets, but...
[23:13] <fsphil> you can probably save cpu time by going straight to ssdv
[23:13] <DL7AD> fsphil.... hum?
[23:14] <fsphil> ssdv will partially decode jpeg and reencode it
[23:14] <DL7AD> but i get a raw image from the SSDV
[23:14] <DL7AD> ehm camera
[23:14] <DL7AD> how?
[23:14] <DL7AD> raw => huffman encoded => decode huffman and JPEG encode => sddv
[23:15] <fsphil> raw > dct > quantise > huffman > ssdv :)
[23:16] <DL7AD> fsphil: thats exactly what im doing.
[23:16] <SpeedEvil> Laurenceb_: Is that a ... paper afterburner tube?
[23:16] <fsphil> all you need from the encoder is the DCT really
[23:16] <Laurenceb_> yes lul
[23:17] <SpeedEvil> 10% extra thrust
[23:17] <Laurenceb_> I guess its protected by a layer of cold air
[23:17] <SpeedEvil> yeah - I suspect it's mostly interesting from a cool pictures POV, rather than massive thrust
[23:18] <SpeedEvil> Or you could just alter the design a bit.
[23:18] <DL7AD> fsphil: i dont get it. i get a raw image. the raw (RBG656) image is too large.
[23:18] <SpeedEvil> Make the input a flap valve, and you've got a pulsejet.
[23:19] <Laurenceb_> I was only interested in a hot air ballute thingy
[23:20] <DL7AD> fsphil: just encoding it to YCbCr is still to large to put it into the memory
[23:20] <Laurenceb_> as it requires a powerful hot air blower that can generate a few hundred Pa
[23:21] <SpeedEvil> pulsejets are actually used as foggers by some
[23:21] <SpeedEvil> Or at least were

[23:30] <fsphil> DL7AD: ideally you do the DCT on 16 lines of RAW data, the resulting coefficients get quantised and packed directly into ssdv packets

[23:31] <fsphil> that's part of the packing stage
[23:33] <DL7AD> fsphil: really? so i dont have to encode into JPEG actually?

[23:40] <fsphil> the green stood out to my eye, the reds only appeared a few times and very faint
[23:40] <fsphil> the camera caught them well though
[23:42] <fsphil> these fuzzy patches kept appearing and disappearing overhead, http://i.imgur.com/ZaNoVY1.jpg
[23:43] <fsphil> they would sometimes just jump, as if something kicked them

[23:44] <gonzo_> excellent pics
[23:44] <fsphil> yeah, and my poor focus
[23:45] <DL7AD> fsphil: so i just do converting RGB into YCbCr, subsample it and send the YCbCr values to SSDV encoding..... right?
[23:45] <fsphil> nope, you'll have to do the DCT too
[23:46] <fsphil> ssdv doesn't have that bit yet
[23:46] <DL7AD> yeah sure
[23:46] <fsphil> the encoder will need a bit of work, the part that reads the jpeg will have to be removed
[23:46] <DL7AD> how does the libary know i feed it with huffman-unencoded data?
[23:46] <fsphil> see above, it doesn't :)
[23:47] <fsphil> it'll need some work
[23:48] <fsphil> the ssdv encoder currently expects jpeg data, but it can be re-written to accept the dct coefficients directly
[23:49] <DL7AD> okay. so i cant do it this way atm?
[23:49] <fsphil> no
[23:49] <DL7AD> :/
[23:50] <fsphil> I think it would be a simpler process than the current encoder, which is a bit mind twisty as it's both decoding and encoding at the same time
[23:51] <DL7AD> yeah just the ssdv functionality is not yet available ;)
