[09:23] <HixWork> thought they may be of interest
[09:26] <Babs> cool. will check it out. looking at the place that printed out my components before, they have now gone pure SLS
[09:26] <Babs> printing in nylon only, vs. the resin i was using from the Objet printer

[09:28] <Babs> the resin stuff was pretty brittle. i will bring some along to the conf so everyone can have fun breaking it
[09:29] <eroomde> i feel like breaking something
[09:29] <eroomde> wtf is a 'risk register'
[09:29] <eroomde> i hate management people
[09:29] <eroomde> i hate them
[09:30] <eroomde> they seem to think that giving everything titles lends their naff concepts some kind of epistemic security
[09:30] <eroomde> you just want to scream 'IT'S BULLSHIT'
[09:30] <eroomde> STOP PRETENDING THIS IS A SCIENCE
[09:30] <SpeedEvil> eroomde: break the risk register
[09:31] <SpeedEvil> having people as a principle try to think of what may go wrong and assess it before leaping in isn't bad.
[09:31] <eroomde> I do that anyway
[09:31] <SpeedEvil> you do.
[09:31] <eroomde> having to showhorn it into some 'complience matrix' where risk is afford a number between 1-5
[09:31] <eroomde> what the holy fuck
[09:32] <eroomde> then they do actual maths with those numbers
[09:32] <eroomde> seriously they need to be punched in the face
[09:32] <SpeedEvil> are the numbers meaning specified?
[09:32] <eroomde> this is so, so, so offensive
[09:32] <eroomde> specified with prose definitons
[09:32] <SpeedEvil> like 2 is a broken toe, and 5 is breaking the sun?
[09:33] <eroomde> i don't even want to go into it
[09:33] <eroomde> i'm going to program some haskell until i feel cleaner

[09:35] Action: SpeedEvil is reminded of http://m.slashdot.org/story/50386
[09:35] <HixWork> I've had a day of workshop induction at my new place. Don't eat solderpaste, Ive been informed. Also if I die, I need to fill in the accident book
[09:36] <fsphil> I've never seen solder paste that looked tasty
[09:36] <HixWork> SpeedEvil ba ha ha
[09:37] <Babs> risk register
[09:37] <Babs> its all about assessing risks in the workplace
[09:37] <HixWork> they didn't tell me about play-doh. that smell wonderful but tastes vile
[09:37] <Babs> are people drinking beer from their bosses wedding in the office, that kind of thing
[09:37] <eroomde> a sad thing a few months ago was the new landlords giving us (rocket propulsion research and testing people) a mandatory talk on fire safety
[09:38] <eroomde> we sat down in the little conference room and the triangle inevitably appeared on the ohp
[09:38] <Babs> tell me you have never squirted paraffin on a barbecue eroomde
[09:38] <eroomde> 'alright guys, to make fire you need 3 things - fuel, air, and a source of heat'
[09:38] <Babs> did he say "its not rocket science"?
[09:38] <Babs> at which point you go "no, but this is. ta daaa"
[09:39] <eroomde> well, you don't need the majority of those things for a fire on a rocket test site
[09:39] <fsphil> rocket people are godo at making fire
[09:39] <fsphil> good*
[09:39] <eroomde> you need neither air nor a source of heat
[09:39] <fsphil> it's the not making too much fire is the problem
[09:39] charolastra (~quassel@188-23-88-168.adsl.highway.telekom.at) joined #highaltitude.
[09:39] <eroomde> we explained this to him and he and we agreed that the remainder of the talk was going to be an enormous waste of our time
[09:39] <HixWork> I don't think anything will ever beat the HSE twat who told an F1 mechanic [who had recently been dragged off down the pitlane after a fuel stop error] that the scalpel blade on his workbench could seriously incapacitate him.
[09:39] <Babs> i once visited one of our businesses and got the only reportable accident that year in the business by scalding myself with a kettle
[09:39] <eroomde> where we differed was that we thought we should therefore leave
[09:39] <eroomde> and he thought he should carry on
[09:39] <Babs> they had worked really hard to get down to zero incidents,
[09:40] <Babs> and then i walked in and f-d it up.
[09:40] <Babs> it wasnt my finest hour
[09:40] <fsphil> ooch
[09:40] <fsphil> pretty much sums that up
[09:40] <eroomde> sometime we just leave something obvious out
[09:40] <eroomde> like a jerry can with the lid off
[09:40] <eroomde> to give them something to add they value onto
[09:41] <eroomde> and not go near the firing bays which they wouldn't understand anyway
[09:41] <eroomde> add their value*
[09:42] <eroomde> i'm sure they didn't have half of this shit during apollo
[09:42] <eroomde> and i refuse to give in to it
[09:43] <Babs> "jerry can"
[09:43] <Babs> it sound as if you need pc training as well

[09:45] <Babs> *eroomde would like to clarify that the picture was in Metro, came off the back of an article on some rocket thing, was of Amanda Seyfried who, at age 27, is older than him
[09:45] <HixWork> you can't beat a nice soft floury bap
[09:45] <Babs> my favourite story on H&S was at Los Alamos during the bomb stuff
[09:45] <eroomde> after an american H&S 'expert' from the site owners came over and told us we couldn't use our reed-bed filtration system (designed to clean up nasties from the firing bay gullies) because 'think of the fishies'
[09:45] <eroomde> i'm not making that up, btw
[09:46] <eroomde> verbatim
[09:46] <Babs> when Feynman walked into the warehouse, saw how closely they were storing the uranium samples, and worked out it was a few inches (US) away from going super critical
[09:46] <HixWork> eroomde I have to say I am 100% behind you, should you choose to go postal over this HSE bollocks.
[09:47] <fsphil> just do it safely
[09:47] <HixWork> Babs I assume a US inch is a lot bigger :)

[12:58] <eroomde> definitely try and nab the 817
[12:59] <astrobiologist_> I fear the 817 is out of my price range... I will see how the price develops. I had heard that 817s go for £400+, 2nd hand! And this one hasn't been used much
[13:00] <astrobiologist_> I was wondering if anybody could comment on the general good-nickness factor and longevity of these two
[13:01] <fsphil> hab tracking.. someone here selling it?
[13:02] <fsphil> my ft817 doesn't do too much hab tracking these days, the fcd++ does the bulk of the work
[13:02] <eroomde> they've not been in existence long enough to know
[13:03] <eroomde> but the yaesu ft-790, for example 9also a great tracking rig) has been around for decades
[13:03] <eroomde> ours still performs like a stunner

[13:08] <astrobiologist_> the 817 on eBay is apparently being sold by someone who bought it for HABbing but didn't use it much
[13:09] <astrobiologist_> I'd be looking for something that could be a spot of habbing but would also be very portable and useful for basic ham use. I picked mfa298's brains on this yesterday. The TH-F7E sounds like a reasonable cheaper alternative if dosh is tight

[13:22] <fsphil> the volume knob is right on the edge, and sticks out
[13:22] <gonzo__> I had a broken vfo encoder on my 857

[13:23] <fsphil> don't use bread board Leyhart
[13:23] <gonzo__> sold as being in gopof condx, but turned out it had bben dropped and the vfo was helbent and hend in with bits of twisted wire
[13:23] <fsphil> gonzo__: hope you give negative feedback
[13:23] <gonzo__> they payed for the replacement encoder

[13:24] <Leyhart> what should I use fsphil in your opinion?
[13:24] <gonzo__> later found that someone had been in to do a wide band mod. looks like they used a biece of coal in tongs as the iron
[13:24] <fsphil> Leyhart: they're unreliable on the ground sitting on a desk with nobody moving or touching it :) think what they'd be like on a swinging falling payload
[13:25] <astrobiologist_> at least the TH-F7E seller is honest about it relative scuffiness, but the photos look O.K. The 817 looks like it is in relatively good nick too. I had been thinking about habbing and (if I get my foundation license) some ham, mainly APRS
[13:25] <Leyhart> I am happy soldering, just wondered if there was a useful stripboard I would be better of using
[13:25] <fsphil> ft817 is a good match to the foundation license
[13:25] <mattbrejza> tbh the pi plate thing isnt breadboard, itll be fine
[13:25] <gonzo__> it's a good radio at any level
[13:26] <fsphil> Leyhart: yea stripboard is vastly better than breadboard
[13:26] <fsphil> ooh it's not?
[13:26] <mattbrejza> fsphil: its this http://www.farnell.com/datasheets/1651396.pdf
[13:26] <astrobiologist_> But the odd thing about APRS, which takes the fund out of it as far as I can see, is that there are iPhone apps that do APRS but do the transmitting for you, all they want is a licensed call sign!

[13:26] <mattbrejza> same for rtty though astrobiologist_
[13:26] <fsphil> hmm I'm not sure what that is
[13:27] <mfa298> doing aprs fully online does seem a bit pointless.
[13:27] <mfa298> a bit like things like echolink when it's just used like skype
[13:27] <mattbrejza> oh right
[13:27] <fsphil> to be fair doing aprs on radio is a bit silly too :)
[13:27] <astrobiologist_> That's what I thought, but there you go. You can buy a cable to do software TNC through the audio socket on your iPhone/iPad, which seems less pointless
[13:28] <gonzo__> relying on gprs/3g coverage for aprs is just daft. at least using radio it's using an AR network
[13:28] <fsphil> or get an arduino to do it

[13:28] <fsphil> you can generate the aprs audio fairly easily

[13:30] <gonzo__> the old ax25 network was great. But it was all killed off by internet/email
[13:30] <astrobiologist_> well, it looks like I can have fun with either rig I'm following, but £175 is probably outside my price range. Be interesting to see what 817s go for. I'm tempted to buy something now, strictly as a scanner, and see if I can set it up and at least listen in to APRS/hab flights etc
[13:30] <mattbrejza> yea that wont go for 175
[13:30] <mattbrejza> itll be at least 300
[13:30] <gonzo__> 817 used will be more than 175£. Unless a real dog
[13:31] <gonzo__> pos sone with a dead PA. If you only want for rxing
[13:32] <gonzo__> if you don't have any rx at the mo, then look at the RTL dongle and habamp. Cheap way to start
[13:32] <mfa298> looking through the completed listing 817-s seem to be between 380 and 420
[13:32] <eroomde> can't be witchcraft to fix a PA
[13:32] <gonzo__> anything is repairable
[13:32] <astrobiologist_> I'm interested in some budget ham. mfa298 was really helpful yesterday (thanks again). APRS is what I am most interested in long term. Outside the U.K it is a good way to track hab. Often used in the U.S particularly
[13:32] <gonzo__> most people just put in a replacement PA board
[13:33] <fsphil> aprs can be done with very cheap FM-only radios

[13:34] <mfa298> As a startup setup I'd probably go either FT817 or UV-3/5R and FCD++ (or all three if you can afford it)
[13:34] <astrobiologist_> curate's egg and all that, at least something like the F7E can receive ssb so can do some jab. mfa298 said it was comparable with the dongles

[13:36] <fsphil> well copied and pasted it
[13:36] <mfa298> just mentioning that domain is a bad word isn't it ?
[13:36] <Babs> agreed. i'm risking getting banned from the channel i know, but it was a quality photo
[13:36] <astrobiologist_> the UV-3/5R is what first got me interested in it all as a serious proposition. I kept getting adverts for those when I looked for PMRs. Rather pay £80 for something 2nd hand that can also receive ssb than £30 for "just" a UV-3/5R
[13:37] <fsphil> well the baofeng can't do SSB (yet)
[13:37] <fsphil> I bet that's coming though

[13:41] <astrobiologist_> Is baofeng a decent brand then?
[13:41] <gonzo__> those cheap raduios are all single chip solutions, and used for all their PMR radios (proper PMR, not 446meg!)
[13:42] <gonzo__> ssb in a single chip is not going to be as easy/cheap for them
[13:42] <gonzo__> baofeng are fine as FM radios
[13:43] <gonzo__> but if you want ssb radio then you are into the yaesu/icom league
[13:44] <astrobiologist_> alright... then gravitating to something like the Kenwood TH-F7E, £80ish 2nd hand, as a decent option to at least receive on sub. I'd buy an 817 if I could afford it... promise
[13:45] <astrobiologist_> ssb not sub
[13:47] <gonzo__> I expect that a F7E would sell for the same in a year or two,so would not be a bad buy
[13:48] <gonzo__> or get an rtl dongle and habamp for SSB (and FM) RX and a cheap HK hheld for FM txing
[13:49] <astrobiologist_> might be able to use a rig at work, I'm quite high up and in a lab on my own ;-)

[14:06] <mfa298> astrobiologist_: that seems to be a case of read the manual. I've seen them both ways around

[16:21] <mfa298> technically I see no reason against powering the Pi from a USB hub, it just feels wrong (Pi plugged into the Input and Output sides of the Hub)
[16:21] <craag> And have drawn 1A from the USB ports no problem.
[16:22] <SpeedEvil> mfa298: may not work on some hubs
[16:22] <Astrobiologist> For something like pocketpacket, it depends on VOX not PTT, so cable "fun" is slightly easier
[16:22] <SpeedEvil> some require vBus before they ebable outputs
[16:23] <Bo_DK_Working> mfa298: ok... dinner time here but will thinker about it
[16:23] <Bo_DK_Working> pm thoughts anyone so i dont loose them
[16:23] <craag> Yep, SpeedEvil is right, but most powoered hubs I've come across have 5V hard-wired to the outputs.

[18:37] <Astrobiologist> Mfa298, famous last words but I think the Kendro wiring is fairly crushproof. If one uses a standard 2.5mm and 3.5mm jack, the only thing I can see is that the two sleeves probably are to the same ground, which is like PTT closed on the diagram.
[18:38] <Astrobiologist> But since something like pocketpacket relies on VOX anyway, this should be O.K
[18:40] <Astrobiologist> Crashproof I mean

[21:25] <fsphil> perfect landing
[21:25] <arko> seriously
[21:26] <SpeedEvil> They're being all 'we expect the first several real-life tests of recovery to fail'.
[21:26] <Willdude123> What should I do about the BBB causing interference?
[21:26] <SpeedEvil> I do hope they nail it and put it into a perfect landing in the ocean.
[21:27] <SpeedEvil> Willdude123: First step would be to try to put it in a tin can - with small holes for the cables - and grounded.
[21:27] <SpeedEvil> with the GPS outside
[21:27] <Willdude123> Really?
[21:27] <SpeedEvil> REally
[21:27] <Willdude123> OK
[21:27] <Willdude123> It is grounded.
[21:27] <SpeedEvil> Batteries inside would be ideal
[21:27] <Willdude123> It's connected to the USB ground
[21:28] <Willdude123> HMM
[21:28] <Willdude123> Not sure that's really the most practical idea
[21:28] <SpeedEvil> Ground at 1.5GHz is a very local thing
[21:29] <SpeedEvil> Any ground connection more than a couple of centimeters away is almost irrelevant
[21:29] <fsphil> it's interfering with the gps?
[21:30] <Astrobiologist> Can I ask another audio lead connection?
[21:30] <Steve_2E0VET> when using a ublox and uno do i wire it tx->tx or tx>rx
[21:30] <Astrobiologist> Basically I want to connect a rig speaker and mic to a computer or iPad
[21:31] <Astrobiologist> I don't want to kill anything by accident
[21:31] <Astrobiologist> Would galvanic isolation help me?
[21:31] <SpeedEvil> fsphil: apparantly
[21:31] <Astrobiologist> Then there's no physical connection, but a transformer inbetween... yes?
[21:32] <K9JKM> I just use the connectors on the soundcard for audio in/out
[21:33] <Astrobiologist> I am a bit concerned about very strong signals on the rig, for instance if I use it for aprs instead
[21:33] <Astrobiologist> Or if I wire up something wrongly. Working out the pinout on some likely rigs was rather complex
[21:33] <Astrobiologist> Could get ground switched etc
[21:34] <Willdude123> SpeedEvil, What do you mean?
[21:34] <K9JKM> My rig has line in and line out levels for interfacing ... if your radio doesn't have those then it is possible to overdrive the signal
[21:34] <SpeedEvil> Willdude123: Regrettably it's too late to be explaining this - I'm going to sleep. Good luck. Can your module take an external antenna?
[21:34] <K9JKM> Switched ground, etc generally presents itself with "nothing works" scenario ... rarely blows things up
[21:34] <Willdude123> No
[21:35] <Astrobiologist> Haven't bought rig yet, ease of linking things up is a consideration K9JKM.
[21:36] <Astrobiologist> Likely a Kenwood F7E, which has speaker/mic ports, so not true line out/line in?
[21:37] <Astrobiologist> Wiring diagram shows jacks also shared with other stuff. Also shows a 10uF capacitor needed in mic line... why?
[21:38] <fsphil> in series?
[21:39] <Astrobiologist> You mean the capacitor fsphil? Yes, in series
[21:39] <fsphil> probably for blocking DC
[21:39] <K9JKM> You can acquire, build or purchase, a device to interface a radio to a computer soundcard ... google for 'soundcard interface'
[21:40] <Astrobiologist> DC=direct current fsphil? Why is this a problem in this context?
[21:40] <K9JKM> With those interface boxes you have your choice of using line-out level signals or speaker-out levels
[21:40] <Astrobiologist> I looked at some likely soundcard interfaces K9JKM, thanks. But the need for self-assembly and the rather odd combination of pins on the Kenwood put me off
[21:42] <Astrobiologist> So I wondered if galvanic isolation bought me anything as a quick fix
[21:42] <Brew> mfa298 - here's what I'm trying to do a Raspberry Pi Tracker with a PiFace attached to do some other controling
[21:42] <K9JKM> Yeah, gotta almost be an engineer
[21:42] <mfa298> Astrobiologist: looking at one of the digrams I think there's an internal pullup resitor on the mic line (so it can feed power to an electrec mic)
[21:43] <Brew> sorry here's the link https://www.dropbox.com/s/kdcr95azpple9ne/WOW%20JBR%20Raspberry%20Pi%20Schematic.graffle.pdf
[21:43] <K9JKM> I think you can buy appropriate cables that match your radio if you get a hold of the RigBlaster brand of interfaces
[21:43] <mfa298> Brew: from what you described earlier it sounds like you've got a reasonable setup
[21:43] <Astrobiologist> Yes, it's mentioned mfa298, as is the fact you can skip the capacitor if you have "DC blocking" on your mic. I must admit I don't know what that means...
[21:44] <Brew> mfa298: cool thanks I'll be back when i have my SSB radio working
[21:45] <mfa298> Brew: a couple of issues you might have is not enoguh power on the 3v3 line for gps and ntx2 (unless you've doing something different to the standard onboard regulator )
[21:45] <Willdude123> Hi
[21:45] <mfa298> if you're flying it on a balloon you'll also need to send some codes to the UBlox so it can work above 18km
[21:46] <mfa298> although as a starting point that looks like it should work
[21:47] Action: cm13g09 mutters something about deigning to respond to that list post....
[21:48] <Brew> Still standard regulator as I've a rechargeable USB power supply at the moment. What's the mod to the UBox? aim is for 30km
[21:48] Action: cm13g09 waits as it sinks in
[21:48] <mfa298> you need to send it a command to put it into flight mode
[21:49] <Astrobiologist> RigBlasters around the $120 mark K9JKM, more than the rig is going for... thanks but looking for economy protection
[21:49] <mfa298> by default it's in a different mode which won't work above 18km (but I think is more accurate)
[21:50] <Brew> is that just a simple one liner or is it a mod to the chip?
[21:50] <mfa298> it's a software command
[21:50] <Brew> ok are there any pointers to that?
[21:50] <mfa298> search the wiki for flight mode and you'll probably find some details
[21:51] <Astrobiologist> iPad with pocketpacket (or similar) can squawk out aprs on the 4 pin 3.5mm jack... if I could just be confident of connecting that sort of thing to a rig without killing anything, I'd bodge from there on...
[21:51] <Brew> I'm just back a the UKHAS wiki now
[21:52] <fsphil> http://ukhas.org.uk/guides:ublox6
[21:52] <fsphil> there's a C example there for arduino-based systems, not too difficult to adapt to other systems
[21:52] <mfa298> Astrobiologist: something that isoloates the two devices should be adequate. Audio transformer, opto isolator or DC blocking cap should do the job

[21:54] <K9JKM> Need to be a bit careful ... some optoisolators are digital '1' or '0' levels which would kill an analog audio signal

[21:58] <ibanezmatt13> Good evening :)
[21:58] <K9JKM> Audio transformers introduce inductance into an interface circuit ... so it depends on the signal rate on how badly additional inductance mangles the signal ... usually 300 or 1200 baud is tolerant but 9600 and above for baud rate gets clobbered
[21:58] <Astrobiologist> Mfa298, so I'd be on the right track with something like this then?: http://www.amazon.co.uk/gp/aw/d/B007VPS7J8/ref=aw_2nd_sims_2?pi=SL500_SS115
[21:59] <ibanezmatt13> Upu: We hot glued the antenna to the bottom of our box today. It looks terrible but I'm sure it'll be fine :) Pics coming tomorrow
[21:59] <Upu> just to 1 up you : http://i.imgur.com/9iNJHwS.jpg
[21:59] <Upu> 2 up you actually
[22:01] <ibanezmatt13> wow
[22:01] <arko> nice
[22:01] <Astrobiologist> K9JKM maybe cheap audio transformers, aka ground loop isolators, would do for me for now? 1200 baud for aprs would do for me for now

[22:02] <ibanezmatt13> ours looks like my younger brother has been let loose with a glue gun and some foam
[22:02] <mfa298> Astrobiologist: I'm not sure if those isolate all of the signal path. I've got something similar so could probably do some continutity tests
[22:02] <K9JKM> It might be worth giving it a try Astrobiologist ...

[22:03] <mfa298> 9600 baud usually needs a different output as well (which I think the F7E can do but possibly not with VOX)
[22:03] <K9JKM> I've directly connected radio to soundcard and used the PC's audio slider controls to set levels ... nothing never blew up ... radio or computer
[22:03] <K9JKM> No need to over design it
[22:03] <K9JKM> Too much signal sucks and that distortion means no decode
[22:04] <Astrobiologist> I was most worried about hurting my iPad K9JKM :-)
[22:04] <K9JKM> Not enough signal makes it look like the interface is dead
[22:04] <mfa298> I've generally done the same. With the F7E I'd possibly just add the DC blocking cap on the mic input (although I've generally worked on the principle that the sound card should have some protection on it)
