[00:04] <craag> That's a lot of vapour coming off
[00:04] <craag> are they venting?
[00:05] <craag> hmm stopped
[00:05] <russss> seems like they're periodically venting
[00:05] <stilldavid> venting what, anyone know?
[00:05] <russss> that'll be the oxygen
[00:05] <hosler> cold cold
[00:06] <russss> the fuel is kerosene so that's less of an issue
[00:06] <craag> ok
[00:07] <stilldavid> was it you russss saying the o2 is kept cold to increase density, they can pack ~20% more per volume or someting?
[00:07] <russss> yeah
[00:08] <craag> countdown going further in the wrong direction
[00:08] <stilldavid> https://twitter.com/elonmusk/status/704092857829732353
[00:08] <stilldavid> would not want to be on the wrong end of that conversation.
[00:09] <SpeedEvil> ^Launch in 9 minutes or so
[00:09] <SpeedEvil> - they've resumed
[00:11] RocketBoy (~steverand@90.195.152.180) left irc: Quit: RocketBoy
[00:11] <russss> aspirational countdown
[00:12] <hosler> do they usually delay a lot?
[00:12] <russss> depends on what they're launching
[00:13] <russss> ISS launches have an effectively instantaneous window
[00:13] <SpeedEvil> :21 new target
[00:13] <SpeedEvil> For GEO, it doesn't matter so much
[00:14] <russss> they have a 90min window but the effective window is a bit shorter due to all this oxygen shenanigans
[00:14] <russss> it seems like :21 is the latest possible time, if they can't get the boat out of the way by then, it's a scrub
[00:15] <stilldavid> how far out are they deploying ses-9? looks like it'll match orbits with another, ses-7 at 35,000km
[00:15] <russss> yeah, geosynchronous orbit
[00:16] <hosler> so will this falcon 9 land itslef like the others?
[00:16] <SpeedEvil> on a barge
[00:16] <stilldavid> the first stage, hosler , ut it's a long shot
[00:16] <SpeedEvil> ideally
[00:16] <hosler> thats friggin sick
[00:16] <stilldavid> they're using most of the fuel to get up to a very high orbit this time.
[00:17] RocketBoy (~steverand@90.195.152.180) joined #highaltitude.
[00:19] <mattbrejza> is this a barge landing attempt?
[00:19] <stilldavid> yup!
[00:19] <russss> theoretically yes
[00:20] <stilldavid> emphasis on _attempt_ this time
[00:20] <mattbrejza> woo
[00:20] <hosler> omg so exciting
[00:20] <russss> yeah it may not have any propellant in it by the time it gets to the barge but they're giving it a go
[00:20] Hix (~hix@97e055a4.skybroadband.com) joined #highaltitude.
[00:21] <hosler> woooo
[00:21] <russss> abort
[00:21] <hosler> nooo
[00:21] <stilldavid> :(
[00:22] <hosler> do they abort a lot?
[00:22] <SpeedEvil> doesn't get any later abort than that
[00:22] <russss> hosler: yeah it happens
[00:22] <stilldavid> better safe than sorry
[00:22] <hosler> yeah
[00:22] <stilldavid> space is hard ¯\_(Ä)_/¯
[00:22] <russss> this vehicle has been cycled a few times so something may have drifted
[00:23] <hosler> do they restart the counter or do they have to inspect it all first?
[00:23] <russss> they'll want to check the data out
[00:23] <SpeedEvil> hosler: it is not going today
[00:24] <SpeedEvil> I suspect
[00:24] <hosler> dang
[00:24] <SpeedEvil> as it's burned some fuel for one
[00:24] <russss> yeah it's likely a scrub for today
[00:24] <SpeedEvil> I think it's vanishingly unlikely they'll have a designed procedure to restart the countdown
[00:25] <hosler> hah yeah
[00:25] <SpeedEvil> So it won't go today

[00:26] <hosler> dang that was my first launch to watch
[00:26] <hosler> or launch attempt i guess
[00:27] <kc2pit> Keep an eye on http://spaceflightnow.com/launch-schedule/ and you'll get plenty more chances.

[00:28] <kc2pit> When their webserver isn't broken, anyway.
[00:28] <hosler> cool
[00:28] <kc2pit> There's typically something launching somewhere every couple weeks, and a fair portion are webcast.

[09:00] <AndyEsser> Ben-AstroSoc: the Pi 3?
[09:00] <Ben-AstroSoc> yeah
[09:00] <AndyEsser> Only found out about it 10 mins ago :)
[09:01] <Ben-AstroSoc> pi hut have em in stock
[09:02] <AndyEsser> I don't have money to splurge on unncessary items like Pis :)
[09:03] <Ben-AstroSoc> me neither :^)
[09:05] <Ben-AstroSoc> 8 hours of lectures today... pls no
[09:06] RocketBoy (~steverand@90.209.204.125) joined #highaltitude.
[09:06] <Vaizki> don't worry soon you'll trade it for 12 hours of trudging work where you learn nothing new
[09:06] <Vaizki> or wait.. did I actually learn almost everything useful doing real work.. why yes :)
[09:07] LunarMobile (~androirc@176.0.62.34) joined #highaltitude.
[09:08] <AndyEsser> I learnt more in 3 years of working than I ever would've done at uni :)
[09:08] <LunarMobile> Hello
[09:11] LazyLeopard (~irc-clien@chocky.lazyleopard.org.uk) joined #highaltitude.
[09:12] <Vaizki> AndyEsser, well tbh mostly uni taught me the basics of "scientific methods" when solving problems, I think that's the most value
[09:13] <AndyEsser> Maybe
[09:13] <AndyEsser> majority of those I learnt at school
[09:13] <AndyEsser> :P
[09:13] <SpacenearUS> New vehicle on the map: 03car_chase - 12http://tracker.habhub.org/#!qm=All&q=car_chase
[09:13] <Vaizki> maybe I wasn't listening in school ;)
[09:14] <AndyEsser> but if I'd gone to uni and done Computer Science or whatever (Rather than electronic engineering) then I'd have come out knowing sod all, thinking I knew everything, and stuck on a rubbish salary :)
[09:15] <Vaizki> oh noes you would have been fully versed in how to write a compiler, how ferrite ring memory works and the O-complexity of sort algorithms!
[09:15] <Ben-AstroSoc> i spent an entire term doing O-complexity of algorithms >_>
[09:16] <AndyEsser> don't get me started on O-notation bollocks
[09:16] <Vaizki> someone needs a hug
[09:16] <AndyEsser> I had enough of a rant about that when I went down and saw ed
[09:16] <Vaizki> hehe
[09:16] <Vaizki> can you tell I did CS then...
[09:17] <AndyEsser> I actually have a rule that if in an interview they ask me to work out the O-complexity of something I'll leave
[09:17] <Ben-AstroSoc> pffft
[09:17] <Ben-AstroSoc> half the time you just count the for loops
[09:17] <AndyEsser> Ben-AstroSoc: nested or side-by-side?
[09:17] <AndyEsser> :P
[09:17] <AndyEsser> makes a difference
[09:17] <Vaizki> I prefer Andy's approach
[09:17] <AndyEsser> It's obviously very important to have an understand of what might be slower, or faster to do
[09:17] <Ben-AstroSoc> nested = increse the power, side by side = increasethe coefficient, no?
[09:18] <AndyEsser> but in the "real world" you implement something, is it fast enough, use too much memory, blah blah
[09:18] <AndyEsser> ok, not fit, lets refactor, try again, and them ove on
[09:18] <Ben-AstroSoc> ye
[09:20] <mfa298> looking back now I see uni as a this is how you learn, here are some basic building blocks and here's some cool stuff to play with. Rather than actually giving me stuff that was uesful in a job.
[09:20] <AndyEsser> ^
[09:20] <AndyEsser> Yea, I think that probably makes sense
[09:20] <AndyEsser> as long as you recognise that early on
[09:20] <mfa298> Most of what I've used in jobs I learnt at uni but in my own time rather than as part of the course.
[09:20] <AndyEsser> and not think "I've just graduated, I know everything, give me dollar dollar bills yall"
[09:20] <AndyEsser> mfa298: the learning outside is the important thing
[09:20] <AndyEsser> the number of graduates I interviewed, who's portfolios or projects were just exactly the same as the next guy
[09:21] <AndyEsser> that's not going to set you apart when I'm looking to hire
[09:21] <mfa298> AndyEsser: agreed, and I don't think I'd have played with the same things had I not been at uni. being able to pick up cheap 486s to play with networking stuff was very useful.
[09:21] <Ben-AstroSoc> i've still got another 3.5 years to go
[09:21] <AndyEsser> mfa298: for the record, I'm not anti-University (as a place to learn, grow, enquire, etc)
[09:21] <Ben-AstroSoc> getting there
[09:21] <AndyEsser> I just typically find most CS students I know, for eg, are useless :P
[09:22] <mfa298> in my first job I was told that one of the things that got me the job was that I'd played with DHCP in my spare time.
[09:22] <AndyEsser> and I feel a large part of that is the lecturers or the degrees
[09:22] <AndyEsser> you sad bastard
[09:22] Action: AndyEsser pushs the DHCP spec away from his desk
[09:22] <AndyEsser> :P
[09:24] <Ben-AstroSoc> tbf i was told when I got the RAL job they liked me for the extra project stuff i'd been doing
[09:24] <mfa298> not sure id spent huge amount of time on it, but it was one of those things that made me stand out from the crowd.
[09:24] <AndyEsser> Ben-AstroSoc: keep the going :)
[09:24] <AndyEsser> always
[09:25] <AndyEsser> that will get you so far
[09:25] <Ben-AstroSoc> will be ^^
[09:25] <AndyEsser> unless you're studying medicine, and your spare time projects involve digging up dead bodies and performing autopsies
[09:25] <AndyEsser> but in a tech sector... just never stop learning
[09:25] <AndyEsser> always be tinkering, or playing, or whatever
[09:25] <Ben-AstroSoc> HAB this year, working at RAL next year, will pick up something fnor final year at aston, and idk what i'm doing the year after tht at cranfinenld
[09:25] <Ben-AstroSoc> cranfield*
[09:25] <AndyEsser> the HAB stuff is an interesting thing to talk about in interviews for example
[09:26] <Ben-AstroSoc> yeah
[09:31] <Vaizki> I used to be one of the principal coders of a MUD (text-based multiplayer rpg for those who are too young).. always a good pickup line.. "when not studying, I'm an omnipotent wizard who controls the fate of thousands of mortals"
[09:33] <AndyEsser> Nerd ;)
[09:33] <AndyEsser> hehe sorry

[09:43] <LunarMobile> Cranfield did some Hab actually, for example on bexus
[09:44] <Ben-AstroSoc> been a while since i looked through the ukhas project page
[09:45] <Ben-AstroSoc> i wanna go there for astronautics + space eng so may well end up working on something while I'm there
[09:48] <edmoore> I helped with the rocket propulsion module at the cranfield astronaitics course
[09:48] <Ben-AstroSoc> oh?
[09:48] <edmoore> it looked like fun
[09:48] <edmoore> yes
[09:48] <edmoore> we designed a sort of lab day using one of our test engines
[09:49] <Ben-AstroSoc> sounds fun
[09:49] <edmoore> and there were a couple of other visits
[09:49] <Ben-AstroSoc> what sorta thing are your engines used for ed?
[09:49] <edmoore> one of them has gone on to do a PhD with my colleague's supervisor
[09:50] <edmoore> have you heard of the SABRE engine being developed by reaction engines in Oxford?
[09:50] <Ben-AstroSoc> yeah
[09:50] <Ben-AstroSoc> i asked the MD for an internship :')
[09:51] <edmoore> recently?
[09:51] <Ben-AstroSoc> last ~3 months
[09:51] <Ben-AstroSoc> was just before christmas
[09:52] <edmoore> so Mark then I guess
[09:52] <edmoore> rather than alan
[09:52] <edmoore> well anyway that's what I do primarily
[09:52] <Ben-AstroSoc> yeah
[09:52] <edmoore> r+d for that
[09:52] <edmoore> but also some other rockety research projects
[09:52] <Ben-AstroSoc> that's pretty cool
[09:55] <edmoore> for cranfield we had left over a little research engine used for some combustion tests for different combinations of things
[09:55] <edmoore> it's simple and works well
[09:55] <edmoore> and well instrumented
[09:58] <edmoore> this is it firing (at night) https://www.flickr.com/photos/eroomde/8371635016/in/dateposted-public/
[09:59] <AndyEsser> so pwetty
[09:59] <Ben-AstroSoc> thats pretty cool :) what do you gain from that that benefits the development of SABRE?
[10:00] <edmoore> that engine? nothing. That was a UK-gov funded thing
[10:00] <edmoore> testing combinations of propellants that could be synthesised on the surface of mars
[10:00] <edmoore> for sample return
[10:00] <Ben-AstroSoc> ah
[10:00] <Ben-AstroSoc> i wasnt aware we were funding stuff like that
[10:00] <edmoore> so, for example, that was using carbon monoxide and oxygen
[10:00] <edmoore> which obviously can be split from the CO2 atmosphere
[10:00] <Ben-AstroSoc> yeah, ISRU
[10:01] <Ben-AstroSoc> didnt know you coudk use CO as rocket fuel
[10:01] <Ben-AstroSoc> huh
[10:01] <edmoore> well it's all a fairly incestuous funding-wise, whether it's esa or uksa or some hybrid thing with matched funding from the TSB
[10:01] <edmoore> (technology strategy board)
[10:01] <edmoore> you can
[10:02] <Ben-AstroSoc> you dont tend to hear mch about what uksa get up to otuside of exomars really
[10:02] <edmoore> the performance isn't stellar
[10:02] <edmoore> you don't maybe
[10:02] <edmoore> i unfortunately am embedded in it :)
[10:02] <Ben-AstroSoc> wouldnt it burn really messily?
[10:02] <edmoore> no, it's quite smooth
[10:03] <AndyEsser> edmoore: is there room in this country for smaller research based companies to get in on the ESA/UKSA/etc funding/research?
[10:03] <Ben-AstroSoc> i guess if you get complete combustion
[10:03] <AndyEsser> or would it all have to be established companies, primarily?
[10:03] <edmoore> AndyEsser: yes of course

[10:32] <R34lB0rg> FuzzyLemon, good to hear
[10:32] <edmoore> in the past landing there caused a CAA investigation

[10:33] <edmoore> thankfully the CAA investigator called a couple of weeks later saying 'so of course you can't control where the winds take it so don't worry about that... this hobby looks brilliant! how did you get started?'
[10:33] <FuzzyLemon> the gopros ran out of battery just before it emerged from the cloud on the way down so they were happy with me keeping it all
[10:34] <Ben-AstroSoc> ohg od what did you do
[10:35] <FuzzyLemon> there was a bit of a panic initially because there happened to be an anti american protest outside the base
[10:35] <R34lB0rg> FuzzyLemon, did you give them a call / warning when you saw the balloon was going there?
[10:35] <FuzzyLemon> they thought the protesters had infiltrated the base with a UFO
[10:36] <R34lB0rg> so they were actually happy it was just a school experiment
[10:38] <FuzzyLemon> they had already found it by the time we called
[10:38] <edmoore> well glad it all went well in the end. School happy?
[10:38] <Ben-AstroSoc> Remind me not to spook the U.S. Govt

I used to get drawn into those kinds of events as well years ago but now I simply read the recap the next morning.

[12:00] <AndyEsser> I say extensinos
[12:00] <AndyEsser> AdBlock Plus and LastPass is all I need

[13:44] <mattbrejza> providing its less than 60m tall i guess lol
[13:44] <SpeedEvil> 2m balloons are as far as I could tell on a quick readthrough exempt
[13:44] <AndyEsser> mattbrejza: heh
[13:44] <AndyEsser> that'd be an impressive balloon
[13:44] <AndyEsser> SpeedEvil: is that not just the standard picoballoon stuff?
[13:44] <SpeedEvil> 'small balloons are exempt from all regulations apart from paragraphs...' - and the 'ground attached balloon' are not mentioned
[13:44] <SpeedEvil> so they are exempt
[13:45] <AndyEsser> cool
[13:45] <SpeedEvil> Do check though
[13:45] <AndyEsser> Was just thinking, for testing launching a rocket from a balloon... potentially easier from a tether for simple testing
[13:45] <AndyEsser> (obviously a rocket launch would require NOTAM anyway)
[13:45] <SpeedEvil> Not quite.
[13:46] <SpeedEvil> From my reading - a small balloon is exempt - and 'small' rockts are also exempt
[13:46] <mattbrejza> upto 160Ns is exempt iirc
[13:46] <SpeedEvil> A careful reading of the ANO seems to indicate that you can launch a small rocket from a small balloon with no issues
[13:46] <Ian_> If you have a large balloon, tethered and it escapes, then it's a bit of a problem . . . handling large balloons is a bit of a nightmare in other than dead calm conditions too

[13:47] <SpeedEvil> Balloons may ascend at - say - 5m/s.
[13:47] <AndyEsser> Ian_: was thinking some sort of 4-point tether to basically prevent it moving in any direction
[13:47] <R34lB0rg> do we know http://earthtosky.net/ ?
[13:47] <SpeedEvil> If the wind aloft is 5m/s, then you will get it going at 45 degrees ith only 5m/s wind
[13:47] <Ian_> That may be optimistic AndyEsser
[13:47] <AndyEsser> and I suspect I'll likely have some sort of safety mechanism on the balloon anyway to pop it if it escapes
[13:47] <SpeedEvil> In that case - even with a four point suspension at 45 degrees - it's going to come down due to aero forces
[13:48] <AndyEsser> boo
[13:48] <AndyEsser> silly aerodynamics and all that jazz
[13:48] <SpeedEvil> Unless it's lifting

[14:42] <fsphil> you have an ISM band up in 900mhz in the US, but it's rarely used for this
[14:43] <mfa298> there might be some license free stuff in the US around 920MHz but I'm not sure how well that would work
[14:43] <fsphil> it's so easy to get an amateur callsign though, worth doing it

[14:54] <fsphil> or be like me and not really use the callsign much at all :)
[14:55] <Ian_> It's not the callsign that is important Phil, but the bit of paper that essentially gives you a large playground to test in.

[15:51] <AndyEsser> Fits in nicely with the qunatity of trackers I'm planning on building (in case I don't recover a single one - whoops)

[15:55] <AndyEsser> edmoore: yea
[15:55] <edmoore> tho you'll doubtless want a 2nd system after a first successful flight
[15:56] <AndyEsser> Although considering making the boards 5x10 so can fit 2 on a single 10x10 PCB from dirty PCBs and then just cutting them in half
[15:56] <Ben-AstroSoc> ours is an awkward size
[15:57] <Ben-AstroSoc> 50x135, can probably knock 15 off the long edge
[15:57] <AndyEsser> I'd love to fit it all on a 5x5 but I think with the charging circuit, RTC, coin cell and SD card it might be a push
[16:00] <edmoore> pfff easy
[16:01] <AndyEsser> edmoore: will try it once I get to the PCB layout stage
[16:01] <gurlavie> which coin cell do you use ?
[16:01] <AndyEsser> most likely a CR2032
[16:01] lilafisch (~lilafisch@irc.xtort.eu) left irc: Ping timeout: 276 seconds
[16:01] <AndyEsser> CR3032*
[16:02] <AndyEsser> but I need to confirm voltages required on the RTC and GPS backup pins first
[16:02] <AndyEsser> if they need +3.3v then I might have a problem
[16:04] <mattbrejza> na just wire the cr2032 into gps backup and rtc
[16:04] <mattbrejza> although checking rather than following people off the internet is generally a good idea
[16:04] <AndyEsser> ^
[16:05] <AndyEsser> It's just one of many things on my To-Do list before I move to layout
[16:05] <mattbrejza> it would be really odd for a backup power supply to be 3.3V +-5%
[16:06] <AndyEsser> with MAX-M8 modules have Max being 3.6v and Min being -0.5v for that pin
[16:07] <gurlavie> do you really need a backup ?
[16:07] lilafisch (~lilafisch@irc.xtort.eu) joined #highaltitude.
[16:07] <mattbrejza> you dont want to be looking at abs max though
[16:08] <AndyEsser> DS3234 VBat = 2.0V to 3.8v
[16:08] <AndyEsser> so a 3v coin cell should be fine for both :)
[16:08] <mattbrejza> :)
[16:08] <AndyEsser> gurlavie: yes :)
[16:09] <mattbrejza> tbh the backup currents are so low you could just run them directly from the lipo
[16:09] <AndyEsser> Didn't want them running off the LiPo :)
[16:09] <hosler> so for a payload box, do i just grab a styrofoam cube and carve out a little hole for everything to live?
[16:10] <mattbrejza> hosler: either that or glue bits to wedge it all in
[16:10] <fsphil> that's what I've done. though getting a pre-made box is a lot handier
[16:10] Action: AndyEsser is totally not planning a ridiculously over-engineered payload box...
[16:10] <AndyEsser> :)
[16:10] <mattbrejza> oh yea i read tht as premade box
[16:11] <hosler> any ole premade one, or are there awesome certified balloon boxes somewhere?
[16:11] <AndyEsser> hosler: what country are you in?
[16:11] <hosler> USA
[16:12] <edmoore> nothing certified, but the thick formed styrofoam containers used to ship dry ice, ice cream, frozen fish etc are popular
[16:12] <AndyEsser> Go to an Arts & Crafts store or similar - they usually have polystyrene boxes/eggs/etc that can be used
[16:12] <edmoore> you can usually get them on ebay
[16:12] <hosler> cool
[16:12] <AndyEsser> or what edmoore suggested
[16:12] <hosler> cool cool cool
[16:12] <hosler> do yall test your parachutes by throwing them off buildings?
[16:13] <hosler> also do i use a detatch mechanism or just wait for balloon to pop?
[16:13] <mattbrejza> depends how much land you have to aim for
[16:13] <hosler> im like 100 miles off the coast
[16:14] <hosler> on land. not at sea
[16:14] <hosler> thats 160 km
[16:15] <edmoore> yes for testing
[16:15] <edmoore> usually let it pop
[16:15] <edmoore> you want to use the predictor really
[16:15] <edmoore> predict.habhub.com
[16:15] <edmoore> see if you flirly with sea landings if you do a typical 5m/s ascent, 5m/s descent, 30km altitude flight

[16:15] <edmoore> flirting*
[16:16] <edmoore> if so you may want to consider some kind of cutdown based on distance from launch or something more sophisticiated
[16:16] <edmoore> predict.habhub.org
[16:16] <edmoore> not .com sorry
[16:16] <hosler> what is most popular method to detatch from baloon
[16:16] <edmoore> i am in the explosives camp
[16:16] <hosler> super sharp knife on servo? lol
[16:16] <edmoore> but that's not a big camp
[16:16] <hosler> oh cool
[16:16] <edmoore> some people try and melt through a nylone wire
[16:17] <edmoore> by passing a current through some nichrome wire which heats up to a nice dull glow
[16:17] <edmoore> wrapped around the nylon string
[16:17] <edmoore> i like pyrotechics though as they're highly reliable
[16:18] <hosler> i was thinking small electromagnet controlled by microcontroller
[16:18] <hosler> i dunno how much power that uses though
[16:19] <edmoore> my first thought
[16:24] <AndyEsser> intresting... I'd have thought pyro's were the most popular, edmoore
[16:25] <edmoore> oh
[16:25] <edmoore> regardless, they're not
[16:25] <edmoore> people seem a bit skittish about making them
[16:26] <AndyEsser> it's not something I've thought about for my first few balloons - but definitely want to try a cutdown at some point
[16:26] <AndyEsser> will investigate the possible options at that point
[16:26] <edmoore> and i have seen people who should know a lot better use pyrotechnics in a very poor way on hab activities
[16:26] <edmoore> so i'm not overflowing with encouragement
[16:26] <edmoore> there probably exists as pyrotechnic, completely safe solution
[16:27] <edmoore> i might make it and sell it
[16:27] <hosler> do it
[16:27] <AndyEsser> my initial thought would be pytotechnic bolt, connecting to eyelets
[16:27] <AndyEsser> and then tie balloon to one end, and parachute/payload to the other end
[16:27] <AndyEsser> two*
[16:27] <edmoore> that's the sort of principle you want
[16:28] <edmoore> the reality is that B&Q tend to not sell pyrotechnic bolds
[16:28] <edmoore> which really do explode
[16:28] <hosler> how about blow dart pointed at balloon
[16:29] <AndyEsser> hosler: doesn't seem particularly reliable
[16:29] <edmoore> what happens after the dart pops the balloon
[16:29] <edmoore> to the dart
[16:29] <hosler> oh good point
[16:29] <AndyEsser> hehe... good point
[16:29] <AndyEsser> :P
[16:29] <hosler> dart on a string then
[16:29] <AndyEsser> sorry, need more coffee - in a funny mood
[16:29] <edmoore> aslways assume your thing will land in someone's back garden with kids playing
[16:29] <edmoore> and that it won't have worked at altitude but instead just come down in a back garden
[16:29] <edmoore> does you firmware will have it armed?
[16:30] <edmoore> does it have loose pieces that fly off if something explodes?
[16:30] <hosler> yeah about that. do yall write a note beore sending it up just to explain wtf it is
[16:30] <hosler> and attach it
[16:30] <edmoore> should you land armed rocket motors in someone's back garden accidently?
[16:30] <edmoore> as a hypotehtical
[16:30] <edmoore> if these questions are not at the top of your list then don't go near pyros
[16:31] <edmoore> you might enjoy my talk on testing parachutes from the 2011 conference
[16:31] <edmoore> i talk about some of the pyrotechnic-but-safe things we used to actuate various this at precise times
[16:31] <edmoore> various things*

[16:33] <edmoore> yes
[16:33] <edmoore> thought with a MOQ that will upset you
[16:33] <edmoore> though*
[16:33] <AndyEsser> MOQ?
[16:34] <AndyEsser> minimum order quantity?
[16:34] <edmoore> and you need some fairly good engineering/machined stuff to turn that protractor into a device that reliable separates something
[16:34] <edmoore> yes
[16:34] <edmoore> turning a pushing pin into an opening-clamp or whatever reliable and accurately needs some fairly careful design
[16:34] <edmoore> and careful machining
[16:34] <edmoore> so stuff doesn't bind up
[16:35] <LunarMobile> We tried a servo based "lock" this time, it seems to have opened but it needed some complex accessories behind it, I.e. heating the servo
