[00:09] <Laurenceb_> ok so I crunched the numbers on UBSEDS-13 envelope
[00:09] <Laurenceb_> 8.5 years float time using hydrogen
[00:11] <Laurenceb_> easy to set a world record with that

[00:32] <richardeoin> nice Laurenceb_
[00:32] <richardeoin> what do you think the limiting factor is?
[00:32] <adamgreig> my 0.5mm pitch BGA worked first time \o/

[00:33] <richardeoin> adamgreig are you routing it or soldering it?
[00:34] <adamgreig> soldered
[00:34] <adamgreig> https://twitter.com/adamgreig/status/690983932343492608
[00:34] <richardeoin> cool

[00:35] <Laurenceb_> richardeoin: def UV damage
[00:35] <Laurenceb_> thats probably going to kill it in < 3 years
[00:35] <Laurenceb_> also weather at 10.1km, probably only a few months on average
[00:36] <Laurenceb_> but if you used the full width (1.8m) it should fly a few km higher
[00:36] <Laurenceb_> adamgreig: nice
[00:37] <adamgreig> also it seems dirtypcbs expand your mask to accommodate their shitty registration
[00:37] <adamgreig> which is a pain when you want mask between fine pitch pins
[00:38] <adamgreig> might try shrinking my mask beforehand next time
[00:38] <Laurenceb_> I also designed a rocket tracker http://imgur.com/a/Uuomc :P
[00:38] <adamgreig> lol
[00:38] <adamgreig> it's a bit blurry
[00:38] <adamgreig> what do you get?
[00:38] <Laurenceb_> yeah I've only ever done small 0.8mm BGAs, but I've run into issues with solder wicking due to mask
[00:39] <adamgreig> amazingly i did get good mask on the bga bit
[00:39] <adamgreig> https://twitter.com/adamgreig/status/691019064374902785
[00:39] <Laurenceb_> its a CW 868mhz tx with a GMR sensor to turn it on and a flashing led
[00:39] <adamgreig> nice
[00:39] <adamgreig> the LED is for your crazy optical tracking scheme?
[00:39] <Laurenceb_> that pcb isnt too bad quality
[00:39] <Laurenceb_> no optical tracking would have to be passive
[00:39] <adamgreig> indeed - but look at this one https://twitter.com/adamgreig/status/691018909206630401
[00:40] <adamgreig> same order
[00:40] <Laurenceb_> but I've kind of given up on that - itd only work for ~25min at twilight
[00:40] <Miek> psh, mask is overrated http://imgur.com/a/POlwA :p
[00:41] <richardeoin> Laurenceb_: yep, definitely need to go a bit higher
[00:41] <richardeoin> bit more pre-stretch will help too
[00:41] <Laurenceb_> Leo worked out a solution to UV damage
[00:41] <adamgreig> mask has its advantages Miek :p
[00:42] <richardeoin> had a qualatex at 8.6km, stretched it a bit more and got 10km

[00:43] <Miek> richardeoin: BAL-NRF02D3
[00:44] <Laurenceb_> those big vias are a bit close O_o
[00:44] <adamgreig> richardeoin: you don't solder the exposed pad on the se880?
[00:44] <adamgreig> weird footprint with those pads on the corners
[00:44] <Laurenceb_> although with plated through hole you dont actually need any copper on the top or bottom layers

[00:46] <Laurenceb_> ah
[00:46] <richardeoin> kida got squeezed in at the end
[00:47] <adamgreig> wish silabs would do some one-piece baluns
[00:47] <richardeoin> adamgreig: there's no exposed pad of the se880
[00:47] <adamgreig> oh
[00:47] <adamgreig> why do you have a big ground pour with vias under it?
[00:47] <Laurenceb_> adamgreig: ST do a few one-piece ones for various stuff
[00:47] <adamgreig> just shielding?
[00:47] <Laurenceb_> but not silabs :-/
[00:47] <adamgreig> maybe i should try the st spirit thing
[00:47] <adamgreig> what was the radio module>?
[00:47] <Laurenceb_> we use it at work
[00:47] <richardeoin> adamgreig: it suggests it in the user manual iirc
[00:47] <Laurenceb_> the st spirit
[00:47] <adamgreig> is it good? is it small :P
[00:48] <adamgreig> i can look these things up myself..
[00:48] <adamgreig> but i am interested in your opinion
[00:48] <Laurenceb_> dunno how good, way better than bluetooth
[00:48] <Laurenceb_> but we aren't exactly running balloons
[00:48] <adamgreig> SPIRIT1?
[00:48] <adamgreig> qfn20 is a good start
[00:48] <Laurenceb_> on paper it might work for balloon comms with a custom board or one of the eval kits on the ground
[00:49] <Laurenceb_> - the module on the ground
[00:49] <Laurenceb_> we use the modules at work as it simplifies CE
[00:49] <adamgreig> it can do 2-FSK at 1kbps
[00:49] <adamgreig> suggests it might be workable
[00:49] <adamgreig> well. wonder what deviation is
[00:50] <Laurenceb_> http://www.st.com/web/en/catalog/tools/PF258319
[00:50] <adamgreig> 'module'?

[00:51] <Laurenceb_> http://www.mouser.com/pdfdocs/DM00133214.PDF
[00:51] <Laurenceb_> ^thats the module, the other thing could run as a ground station if you wanted uplink... maybe
[00:51] <adamgreig> hmm
[00:51] <adamgreig> module has an stm32l1 inside, that's nice
[00:51] <Laurenceb_> very speculative, I havent tried anything similar in the lab
[00:52] <Laurenceb_> there is an eval board that the PF258319 thing can plug into somewhere
[00:52] <Laurenceb_> with the right firmware so its plug and play - too easy :D
[00:53] <adamgreig> 400Hz minimum deviation
[00:53] <adamgreig> for 2fsk
[00:53] <adamgreig> would be fine for even classic hab
[00:54] <adamgreig> any thoughts on how it compares to the si4460 sort of thing?
[00:55] <Laurenceb_> best poss link budget is slightly worse
[00:55] <Laurenceb_> if you want 2 way link that is
[00:56] <adamgreig> even more matching components than the si chip
[00:58] <Laurenceb_> also the silabs modem is more configurable
[00:58] <Laurenceb_> so once you spend ages working through the undocumented stuff AFC will run well
[00:58] <adamgreig> lol
[00:59] <Laurenceb_> SPIRIT1 "just works", but you dont have the flexibility to push it to the limit
[01:00] <Laurenceb_> but then again on the other hand, I solved the problems and code is on my github
[01:02] <Laurenceb_> I think a lot of it will come down to how the SPIRIT1 modem handles interference at altitude if you are trying to do an uplink
[01:03] <Laurenceb_> and I have no data on that

[10:23] <fsphil> yes, robin hood, that famous welshman
[10:24] <criticalmass> What do I need to do to register as an actual tracker? I doubt with the equipment I have I'll be able to get anything yet, but I'd like to give it a go.
[10:24] <criticalmass> "hand over all your money, see boyo"
[10:24] <fsphil> just run dl-fldigi, fill in a callsign (can be anything) and the coordinates
[10:25] <fsphil> assuming you decode something it should then get submitted to the map
[10:25] <criticalmass> Oh OK. I don't need to register a call sign with habhub.org or out?
[10:25] <fsphil> nah. you only need that for the payloads themselves

[10:32] <AndyEsser> think I'll have some croissants for breakfast
[10:32] <gonzo_nb> the smell of burned toast and the scraping of it, reminds me of childhood
[10:33] <gonzo_nb> the smoke alarm was always used as the dinner bell when I used to share a house. it told you that the steak was done
[10:33] <AndyEsser> ewww
[10:33] <AndyEsser> steak should never set a fire alarm off
[10:33] <AndyEsser> Tells you steak is too well done
[10:34] <gonzo_nb> dealind with 4 kids (I include the step father in ythat count) dogs, cats, coal fires. My mother was pretty rushed in the mornings. So burnt toast was common for breakfast
[10:35] <gonzo_nb> eeeee, we 'ad it tough, tha' knows.
[10:35] <AndyEsser> Back when I were a lad, we'd be lucky to even get bread, let alone toast!

[12:29] <fsphil> this is where I went wrong with all my launches. no hot food/drinks at the launch site
[12:29] <AndyEsser> I had a nice long chat with my brother last night about my first launch - he was asking loads of questions
[12:29] <AndyEsser> we're going to get the MD to come along with the company drone and follow it up for a bit and try to get some awesome photos
[12:30] <Vaizki> interest is good

[12:31] <AndyEsser> already told him that
[12:32] <fsphil> or if something isn't working quite right
[12:32] <eroomde> i think most of us have a war story from when we didn't want to launch but the tv crew was coming so we had to anyway
[12:32] <eroomde> and it ends up in the sea, the end
[12:32] <fsphil> I had to cancel a launch at a ham event because of bad code
[12:32] <AndyEsser> TBH - since my first launch won't have camera or anything, I'm not too concerned if I don't recover it
[12:32] <AndyEsser> but it would b enice
[12:32] <AndyEsser> be nice*
[12:32] <gonzo_> I had to wait for bad wx to launch. As my notam stopped me launching in what was normal direction winds
[12:33] <gonzo_> had to wait for a weather friont to come through
[12:33] <AndyEsser> My main concern is trying to make it feel exciting for any of the kids that'll be along
[12:33] <gonzo_> a foil pico is a cheap woy to test your tracker
[12:34] <fsphil> let them launch a little red balloon, to check wind direction
[12:34] <gonzo_> and a pico, you can let the kids do the release
[12:34] <AndyEsser> gonzo_: yea - toyed with the idea of just doing a pico to test the hardware
[12:34] <AndyEsser> fsphil: that's a good idea actually :)
[12:35] <gonzo_> what about the other 98??
[12:35] <AndyEsser> 98?
[12:35] <gonzo_> red balloons
[12:35] <AndyEsser> ah
[12:35] <AndyEsser> sorry... didn't get that
[12:35] <AndyEsser> my bad
[12:35] <gonzo_> sorry
[12:35] <gonzo_> nope, I'm worse
[12:35] <fsphil> lol
[12:36] <fsphil> for a moment there thought AndyEsser had 99 kids coming to the launch
[12:36] <AndyEsser> fsphil: that's what I thought he meant
[12:36] <AndyEsser> then I Was really panicking!
[12:36] <gonzo_> now that is one for the list!
[12:37] <fsphil> someone, can't remember who sadly, talked about when they let go of the HAB one of the kids there started crying
[12:37] <gonzo_> at one I went to in .de, it seemed like there were 99kids. Well, students.
[12:38] <AndyEsser> fsphil: aww
[12:38] <fsphil> they wanted to keep the giant balloon :)

[13:17] <criticalmass> :-)
[13:17] <eroomde> anyway, so back in the day this was how we did it
[13:18] <eroomde> you'd just email the list with the rtty settings
[13:18] <eroomde> we'd set up fldigi (before dl-fldigi) appropriately like you just did, and then there was a python script which would look at the text log fldigi could save, and find good telemetry strings, and upload them to spacenear.us
[13:18] <eroomde> fldigi is nice because it automotates all of that now
[13:19] <eroomde> it gets the settings from the payload doc and automatically sets up fldigi's modem to the right thing and automatically uploads good strings
[13:19] <criticalmass> Like I said before, this is all very much outside of my comfort zone. I'm a complete noob so thank you for your help.

[13:20] <criticalmass> So I'll add 'setting up a payload doc' to my list of things to learn :-)

[13:35] <criticalmass> So I'm tuned into a couple of WEB SDRs that Mike gave be earlier - 434.3 USB. Do you think I'm likely yo pick up CRAAG's payload st some point?
[13:36] <Geoff-G8DHE> Good chance
[13:36] <eroomde> if they're within a couple of hundred km of the the predicted flight path, i'd have thought there'd be a good chance
[13:36] <AndyEsser> The Farnham one should pick it up pretty quickly when it finally launches
[13:36] <Geoff-G8DHE> especially SUSW
[13:36] <MatB> Hmm. Now I've turned the house upside down looking for my audio lead I find my new laptop has one unmarked audio jack, which I imagine is for headphones...?
[13:36] <redmi> Hello to everybody, someone uses the habduino with the APRS module? I understand that APRS reports the position (144 MHz) in a different way then the RTTY UKHAS protocol (434 MHz)
[13:36] <Geoff-G8DHE> SUWS rather
[13:37] <criticalmass> Excellent. The dogs will have to wait for their walk 😃
[13:38] <AndyEsser> "Damnit dogs, you have to wait, can't you see I'm trying to science!"
[13:38] <criticalmass> hahahahahaha
[13:38] <criticalmass> "I'm trying to science"
[13:38] <criticalmass> I actually snorted.
[13:38] <AndyEsser> science is a perfectly acceptable verb
[13:38] <AndyEsser> I science, You science, He/She/It sciences... etc
[13:38] <criticalmass> Indeed
[13:38] <AndyEsser> :)
[13:38] <redmi> I have been digging the web to know exactly how it is sent the information from the habduino in APRS but I can't find it

[13:39] <criticalmass> I'll stop there
[13:39] <fsphil> redmi: aprs is quite a bit different from rtty
[13:40] <criticalmass> MatB: It's either going to be a line out/headphones or a mic in.
[13:41] <criticalmass> Or the hole you use to fill up the screenwash
[13:41] <redmi> fsphil: I see. The dl-fldigi can decode APRS?
[13:41] <fsphil> it can't
[13:42] <fsphil> there is software that can, but none are very friendly
[13:42] <redmi> Ok. I have heard something about TNC, which I suppose that decodes via hardware the APRS position.
[13:43] <daveake> You can use a PC with s/w decoder

[13:45] <redmi> daveake: thank you for the hint. Do you know if there is a way in which aprs-fi can be linked to spacenear.us?
[13:45] <daveake> There is
[13:45] <criticalmass> There are certainly some third party sound card drivers that have that functionality
[13:45] <daveake> Though most people just use the aprs.fi map, I think
[13:45] <Oddstr13> isn't aprs nfm modulated 1200 baud 2fsk or some such?
[13:45] <fsphil> AFSK
[13:46] <fsphil> two tones, modulated with NFM
[13:46] <mfa298> redmi: in case you're not aware, aprs requires you to have an amateur radio license for the commin frequencies, the 434MHz rtty we use is license free in parts of the world (Mainly Europe)
[13:47] <Oddstr13> hm... wonder if a generic sound modem would sufice
[13:47] <redmi> mfa298: one person in the team has the license :), but I'm trying to understand everything
[13:47] <fsphil> yeah lots of people use the output of the radio into sound cards
[13:48] <fsphil> the two tones are only 1200hz and 2200hz, well within the bandwidth of a sound card
[13:48] <redmi> because he suggests to move from UKHAS protocol to APRS since there are lots of aprs users in Spain

[13:49] <mfa298> redmi: both have advantages, if you can it might be worth running rtty and aprs
[13:50] <daveake> this ^
[13:52] <redmi> mfa298: aprs modules works on 300 mW which is 30 times stronger than UKHAS protocol. Isn't this the main factor? Apart from the fact that there are much more aprs users than people capable of listen SSB, at least in Spain.
[13:52] <Geoff-G8DHE> Oh Craag4 flyoing ?
[13:52] <fsphil> FM modulation is not as efficient as SSB that the ukhas system uses
[13:52] <Geoff-G8DHE> perhaps not

[13:53] <Geoff-G8DHE> I know im tracking but it suddenly went up to 310m!
[13:54] <mfa298> redmi: power alone doesn't make much difference, the license free 10mW has managed 800km, on aprs you're also competing with ground stations that could be running 5-50W (and some more)
[13:54] <mfa298> and what fsphil said
[13:54] <criticalmass> So on the Hab Tracker map, does the green line to a mast mean that tracker is currently tracking it?
[13:54] <eroomde> yes
[13:54] <criticalmass> More stupid questions to follow...
[13:54] <eroomde> but i suspect they have the location of the mast a bit wrong
[13:54] <Geoff-G8DHE> It means it has seen the laste telemetry burst yes
[13:55] <criticalmass> Cool
[13:55] <redmi> fsphil: can you explain a little this? In case that I can convince my mate. Also, it seems that if I go with the SSB I will be the only listening.
[13:55] <criticalmass> What about a red line?
[13:55] <eroomde> i don't see any red lines
[13:55] <mfa298> the real benefit that APRS brings is an existing listener network, the UKHAS rtty usually brings a quieter band, more frequent updates and the possibility for things like ssdv
[13:55] <Geoff-G8DHE> That is movment, currently where it was last tested in Southampton to wales!
[13:55] <criticalmass> Not now, but there was earlier.
[13:55] <G8FJG> track line
[13:55] <criticalmass> Ah, I see
[13:56] <criticalmass> That's why then.
[13:56] <eroomde> redmi: if you do AFSK, the energy required, per bit, for a given bit-error rate, is much higher than with FSK in ssb.

[13:57] <redmi> erromde: but anyways with aprs you only transmit each few minutes (I think 2 min) compared with SSB
[13:57] Hix (~hix@97e0a009.skybroadband.com) joined #highaltitude.
[13:58] <eroomde> yes that too
[13:58] <eroomde> there are lots of reasons
[13:58] <eroomde> but the main reason we went with fsk for our 10mW uk allowance is
[13:58] <craag> yo
[13:58] <craag> balloon filled
[13:58] <Geoff-G8DHE> also if you need to direction find the payload on landing much easier with RTTY than APRS
[13:58] <mfa298> with ssb you could transmit every few minutes if you wanted to, but ssb lets you send telemetry all the time, APRS doesn't (grumpy people get upset when you send data too often on aprs)
[13:58] <craag> armpits soaked
[13:59] <eroomde> 1) we don't need linear power amps (for PSK) which is less efficient for the amplification stage
[13:59] <eroomde> 2) FSK is better than anything else when you are power constrained but not bandwidth constrained
[13:59] <chris_99> cool craag, going to launch soon?
[14:00] <redmi> I really prefer UKHAS protocol since it is very well documented and I'm newby to radio stuff, but the main con is that we don't have any listeners as you have in UK
[14:01] <eroomde> yeah
[14:01] <eroomde> we probably would have gone with aprs 10 years ago if it was available to us
[14:01] <eroomde> but it wasn't, so we had to invent our own thing
[14:01] <eroomde> and i think the community is all the better for it
[14:01] <AndyEsser> and FSK is just so easy to implement
[14:02] <redmi> yes, I see that the community UKHAS is awesome and the aprs community is much more scattered
[14:02] <eroomde> AndyEsser: PSK would be as easy with the right radio
[14:02] <eroomde> we just happened to have ntx2s
[14:02] <AndyEsser> ah fair enough
[14:03] <eroomde> PSK31, a plausible mode habs could have used, just has a single carrier whose phase you flip 180 degrees every bit change
[14:03] <eroomde> and you decode it (bpsk) as a described in my gps talk
[14:03] <eroomde> with the costas loop
[14:03] <AndyEsser> that GPS stuff was really awesome
[14:04] <criticalmass> When buying an ntx2, do people normally specify a frequency or just opt for a random one?

[14:18] <Oddstr13> hehe
[14:18] <mfa298> I think a fair number of people have tracked using the web sdrs, just use the sdr location in dlfldigi rather than your own or the map gets confusing (suws websdr has coords to use on the page I think)
[14:19] <dbrooke> PE2BZ: there are normally only some sensors at 433.92 but this signal seems probably strong enough to wipe out my HAB tracking

[15:26] <chris_99> just to clarify, with GQRX, am i right in thinking you'd see just a straight line on the waterfall, and using USB, make sure the grey chunk of 4kHz, covers that line?
[15:27] <Oddstr13> zooming in a bit should give you a line looking more or less like this; https://dl.dropboxusercontent.com/u/4306267/ShareX/2016/01/2016-01-24_16-26-41.png

[15:32] <AndyEsser> FFT resolution is already at 524288
[15:32] <Geoff-G8DHE> your offset isn't helping either you should see the baseline noise
[15:32] <AndyEsser> Geoff-G8DHE: Yea, that's gone again - was just trying to declutter when I thought I might have it
[15:32] <mfa298> AndyEsser: what antenna are you using on it ?
[15:33] <AndyEsser> the standard one that comes with the RTL-SDR - so it's a bit shite
[15:33] <Oddstr13> a bit? xD
[15:33] <Geoff-G8DHE> and its burst anyway

[17:35] <criticalmass> SDR Sharp is doing my head in. On start, the spectrum analyser seems to be doing its job ok but the moment I move the frequency range either way or zoom at all, it just drops down to almost nothing and stays there, even when there's a strong signal in the waterfall.

[17:42] <Lunar_Lander> how comes max alt is just 10 km?

[17:57] <criticalmass> Yep, so use the range slider to reduce lower part of the spectrum. Understood. It just so happens that I left them in different positions for the screenshots. And the filter. But the moment I drag the spectrum left or right or touch the zoom slider, I lose all movement on the spectrum analyser and it just drops off. Only way I can get it back again is to
[17:57] <criticalmass> shut it down and run again.

[19:02] <eroomde> at one end you have nixie tubes for your power meter, but apparently that's boring and overdone (aswell as just silly)
[19:02] <eroomde> so how refreshing, then to have a power meter that *merely* has an entire web server
[19:08] <mfa298> criticalmass: might be as cheap to invest in reasonable coax, something like RG213
[19:08] <criticalmass> Yeah, I don't think I want to go down the long USB cable route tbh.
[19:10] <mfa298> if the sdr your using can provide bais-t power you can also power an lna at the antenna end that way.
[19:17] <criticalmass> Hmm, I doubt it does. It's just the cheap one from RTL-SDR.com
[19:19] <eroomde> it's not a problem - you can stick one in-line after the rtl-sdr connector
[19:20] <mfa298> with a well placed antenna and decent coax you may not need an LNA anyway
[19:20] <eroomde> quite so
[19:21] <eroomde> best have a stab without and solve it if it looks like it might be a problem
[19:21] <eroomde> and easy enough mod once you've done the legwork of getting an antenna up
[19:23] <mfa298> the modified rtlsdr sold on rtlsdr.com suggests you can enable bias-t with a bit of solder.

[20:14] <criticalmass> On the tracker, when a chase car goes green. does that mean the payload has been retrieved?
[20:14] <richardeoin> doubt it
[20:14] <richardeoin> the colours are just random I think
[20:15] <criticalmass> The balloon track has gone green now too.
[20:15] <richardeoin> and are set when you re-load the tracker
[20:15] <criticalmass> Sorry, not the icon itself, the track.
[20:15] <criticalmass> Ok, so the track is a random colour too?
[20:16] <mfa298> I think the path colours just match the balloon/car, and will change as you reload
[20:16] <mfa298> car's don't normally show the path they've taken unless you click the path button

[21:39] <fsphil> that moment happens suprisingly often
[21:40] <Laurenceb_> black magic probe?
[21:40] <Laurenceb_> I can never make that thing behave
[21:40] <Laurenceb_> yet st-link "just works"
[21:41] <adamgreig> huh, what are you doing with it?
[21:41] <adamgreig> like, how is it misbehaving?
[21:41] <adamgreig> mine always "just works" much much easier than st-link
[21:41] <Laurenceb_> the gdb server.. probably pebcac
[21:41] <Laurenceb_> tbh I've never used it in anger
[21:42] <Miek> adamgreig: it looks different :)
[21:42] <Laurenceb_> I see you have a 'MYS' F1, we had issues with ESD protection on that at work
[21:42] <adamgreig> oh yea?
[21:42] <Laurenceb_> it looks like they changed the fab process
[21:43] <adamgreig> what does MYS refer to? the '2' is the silicon revision aiui
[21:43] <Laurenceb_> MYS is the country, presumably the fab
[21:43] <adamgreig> mm
[21:43] <Laurenceb_> we had a board design that injected a few mA for a few ms
[21:44] <Laurenceb_> no issues on many hundreds of board, then we get a reel of the MYS F103 and every board dies within a month
[21:44] <Laurenceb_> same with other reels
[21:44] <Laurenceb_> that was expensive to fix :-/
[21:45] <adamgreig> jeez
[21:45] <adamgreig> weird
[21:45] <adamgreig> upsetting
[21:45] <Laurenceb_> had to do a recall - the ESD diodes got fried and there was a constant ~10µA current into GPIO pins

[21:48] <Laurenceb_> I'm not sure if the sensitivity to ESD type events is much changed - ~2mA for ~10mS is not that similar to an ESD
[21:48] <adamgreig> yea was gonna say. but it was enough to fry the ESD diodes huh
[21:48] <adamgreig> what voltage was the 2mA injection? surprised enough to cause the ESD diodes to conduct even
[21:48] <Laurenceb_> about Vcc + 0.8v
[21:49] <Laurenceb_> 4.1v or something
[21:49] <Laurenceb_> on a non 5v pin
[21:49] <adamgreig> ah ok
[21:49] <adamgreig> probably I will not have that issue :P
[21:49] <Laurenceb_> it was a vreg misbehaving on power on
[21:49] <adamgreig> really i want to try and spin a black magic probe that works with an F0 doing crystal-less USB
[21:49] <Laurenceb_> yeah
[21:50] <adamgreig> then I don't need the 22R, the 1k5 pullup, the 8MHz xtal or its caps
[21:50] <adamgreig> and can use a cheaper stm32 to boot
[21:50] <adamgreig> which would be nicer all around really
[21:50] <Laurenceb_> build it into the USB connector :D

[21:56] <adamgreig> I probably would if I really knew what they did :P
[21:57] <richardeoin> and wanted the adjustable regulator and such
[21:57] <adamgreig> one kinda goes red if there's a problem and one flashes when it's doing activity and one is for the serial port?
[21:57] <adamgreig> yea - so I had all these ideas of things that would be nice, adjustable regulator, isolation, level conversion, etc
[21:57] <adamgreig> but then it just never got made
[21:57] <richardeoin> there's one that flashes for every page written
[21:58] <adamgreig> this was simple enough to just throw the pcb together with another order
[21:58] <Laurenceb_> yeah thats the one issue I have with st-link, I've run into ground loop issues on several occasions
[21:58] <adamgreig> and does everything 90% of people who want to borrow mine need

[21:58] <Laurenceb_> even fried a board and myself on one occasion
[21:58] <adamgreig> jeez
[21:58] <adamgreig> I discovered that the new desks in the new dyson centre have a) USB power sockets built into the power sockets
[21:58] <adamgreig> b) they're isolated, ground isn't tied anywhere
[21:58] <Laurenceb_> workshop with some sort of weird main issues
[21:58] <adamgreig> c) 100V AC between their USB GND and earth
[21:58] <Laurenceb_> *mains
[21:59] <adamgreig> d) the desks are all metal-rimmed and all the metal is earthed
[21:59] <Laurenceb_> eeek
[21:59] <adamgreig> high impedance so it's just like a gentle tingling in your heart when you touch the usb shield while also resting on the bench
[21:59] <adamgreig> :P
[21:59] <Laurenceb_> there is a dyson center at Cambridge?
[21:59] <adamgreig> you'd think if you sell mains sockets that have builtin USB PSUs you'd ground the earth

[22:04] <adamgreig> huh
[22:04] <adamgreig> what did you do with it?
[22:04] <Laurenceb_> used it for random pneumatics and pipe parts :P
[22:05] <Laurenceb_> guess I have no appreciation of "art"

[22:10] <adamgreig> which slot?
[22:10] <adamgreig> the two on the right hand side were in the datasheet for the serial connector
[22:10] <adamgreig> but it turned up and doesn't have anything that goes into the slot
[22:10] <adamgreig> so ?_?

[22:19] <criticalmass> Does anyone use a service like irccloud?
[22:20] <criticalmass> I've found it very useful, but not sure if I can justify the £35 a year pricetag.
[22:21] <adamgreig> irccloud's very nice
[22:21] <adamgreig> i run my own server and run an irc client on that the whole time, which my phone can connect to, so same sort of deal
[22:21] <adamgreig> a lot more expensive than £35 a year
[22:21] <adamgreig> (but i get a lot of other things out of it of course)
[22:22] <mattbrejza> what was the problem?
[22:23] <adamgreig> think I just didn't program the bootloader+main firmware to the right memory first time
[22:23] <adamgreig> think i might have just not programmed the bootloader at all :P

[23:42] <fsphil> any longer an exposure and it would've been all blurry
[23:42] <Geoff-G8DHE-Lap> Also think the scope needs abit of collimating on ine
[23:42] <Lunar_LanderA> my prof told me a story
[23:43] <Lunar_LanderA> in 1986 he was on camping holiday in france and he met a british man who liked astronomy and they talked about that
[23:43] <fsphil> I've never got a good picture of another galaxy so far
[23:43] <Lunar_LanderA> and then the man's wife came with a baby girl and he said "that's my daughter Halley"
[23:43] <Geoff-G8DHE-Lap> Hoping to get M101 at some point!
[23:43] <MikeUoN> awww ll :)
[23:43] <fsphil> oooh yes, that would be good
[23:44] <Lunar_LanderA> :)

[23:44] Darkside (~darkside@compsci.adl/officialscapegoat/Darkside) joined #highaltitude.
[23:44] <MikeUoN> Unfortunately Uni Campus isn't the darkest place to take pictures :-(
[23:44] <fsphil> M31 is just too big
[23:44] <fsphil> I've never got anything more than a fuzzy blob
[23:45] <Geoff-G8DHE-Lap> All those so far are from backgarden in Worthing but seeing as my Son got me the scope I've warned him he is going to have to drive me out to a some local spots in th edark!
[23:45] <fsphil> does your scope track the stars?
[23:46] <MikeUoN> Have you seen the 1.5 billion pixel image of m31
[23:46] <Geoff-G8DHE-Lap> yes added a motor first thign!
[23:46] <fsphil> hah, excellent
[23:46] <MikeUoN> nice
[23:46] <fsphil> the orion nebula looks nice even through the eyepiece
[23:47] <Geoff-G8DHE-Lap> Yes it does, I need to learn to navigate to the HorseHead as well another target on my lsit!

[23:49] <Laurenceb_> moar crackpottery
[23:50] <MikeUoN> Whats your favourite deep sky object?
[23:52] <Geoff-G8DHE-Lap> http://www.g8dhe.net/pictures%5C2016%5C01%5C20160124/dsc_7144.jpg
[23:52] <fsphil> that's a heck of a setup
[23:52] <Geoff-G8DHE-Lap> quick image of the scope in the living room
[23:53] <Geoff-G8DHE-Lap> not really a Jessop special!
[23:53] <fsphil> orion neb def. my fav. it was the first thing I saw through a scope
[23:53] <MikeUoN> nice
[23:53] <Geoff-G8DHE-Lap> Horsehead and M101 for me at present
[23:53] <MikeUoN> I like Eagle
[23:54] <fsphil> jupiter is another fav
[23:54] <fsphil> not really deep sky
[23:54] <Geoff-G8DHE-Lap> yes will have to get up early one morning and perhaps do a Pano of them all.
[23:55] <fsphil> mars has never looked more than a featureless disc to me
[23:56] <Geoff-G8DHE-Lap> Not really had a chance took at the planets much yet, jupiter and 3 moons first night and that's it!
[23:56] <MikeUoN> It always amazes me how detailed the drawings on 'canals' on Mars were from the 19th century
[23:57] <fsphil> I've never seen the great red spot
[23:57] <MikeUoN> :O
[23:57] <fsphil> seen the cloud bands it should be in, but it always seems to be on the night side
[23:59] <fsphil> just bad timing
[23:59] <Geoff-G8DHE-Lap> and its getting a lot smaller than in the past!
[23:59] <MikeUoN> Oh yeah, that's quite interesting
[23:59] <fsphil> yeah seen some of the before/after pics. it's shrinking fast
