[13:58] <edmoore> hi jcoxon
[13:58] <jcoxon> hey edmoore
[13:59] <jcoxon> was thinking about your altoids payload
[13:59] <jcoxon> you could make the gm862 python monitor sms
[13:59] <edmoore> uhuh?
[13:59] <jcoxon> if you send it a text it'll interpret it
[13:59] <edmoore> that's very much the plan already
[13:59] <jcoxon> oh right
[13:59] <edmoore> for example I want to be able to activate one of thos rape alarms the rocketry chaps use
[13:59] <edmoore> by sms
[14:00] <edmoore> so when we're hunting around in a field full of whatever and we know we're close but can't see it yet....
[14:00] <edmoore> or maybe a smoke bomb :)
[14:00] <edmoore> I'm quite excited about the abilities of these modules
[14:01] <edmoore> and I like your idea of the gps going direct to the telit module aswell
[14:03] <jcoxon> yeah
[14:03] <jcoxon> lots of potential
[14:03] <jcoxon> especially once coupled with another processor
[14:05] <edmoore> if BGA wasn't as issue i'd be mighty tempted by those pro ones
[14:06] <jcoxon> yeah
[14:08] <jcoxon> does superglue melt rubber?
[14:08] <edmoore> btw it's now called High Altitoid
[14:08] <edmoore> some does
[14:08] <edmoore> I'm not sure which glue melts which rubbers, though
[14:09] <neontube> do u want it t melt it?
[14:09] <jcoxon> no
[14:09] <jcoxon> i'm splicing coax
[14:09] <edmoore> Epoxy might be better
[14:09] <jcoxon> and i put some heatshrink to shield the center line
[14:09] <neontube> with superglue :s ?
[14:10] <jcoxon> it doesn't
[14:10] <jcoxon> melt it that is
[14:11] <jcoxon> High Altitoid
[14:11] <jcoxon> very good edmoore
[14:11] <edmoore> :p
[14:11] <jcoxon> been writing some code for firefly
[14:12] <jcoxon> gone back to basics - nice and simple
[14:12] Action: jcoxon just watched Thunderbirds on itv2
[14:12] <jcoxon> how i used to love that show
[14:15] <edmoore> i stil do!
[14:16] <jcoxon> which thunderbird?
[14:16] <edmoore> 2 was the one i always emulated in my lego models
[14:16] <jcoxon> i think everyone loves 2
[14:16] <edmoore> ha, my online tv times thing is amusing
[14:17] <edmoore> on more 4 currently there's location, location, location
[14:17] <edmoore> except it's a quadruple bill
[14:17] <edmoore> so it says location, location, location, location, location, location, location, location, location, location, location, location,
[14:17] <jcoxon> hehe
[14:24] <edmoore> the last bit of the yule log is finally gone
[14:24] <edmoore> twelfth night. that was good timing!
[14:24] <jcoxon> not bad timing
[14:27] <jcoxon> :-) got a gps lock indoors
[14:27] Action: jcoxon remembers the days of hanging out windows to get a lock
[14:31] <jcoxon> that actually took up half my development time

[14:48] <edmoore> tho I couldn't tell you right now where it is....
[14:48] <jcoxon> :-)
[14:48] <jcoxon> just seeing if i need to order a new one
[14:48] <edmoore> it's in one of my boxes that i brought home but haven't touched all holiday

[15:38] <jcoxon> HEY neontube
[15:39] <jcoxon> oops capitals

[15:40] <jcoxon> canada water so south london
[15:40] <jcoxon> should be able to
[15:40] <neontube> i'm down at a show for work
[15:41] <jcoxon> cool
[15:41] <jcoxon> well yes, i can make it
[15:41] <neontube> i'll bring one down with me then
[15:41] <jcoxon> cool
[15:42] <jcoxon> would you like a donation for it?
[15:42] <neontube> W.H.Y.
[15:43] <neontube> i don't want cash for it, just fixing it at the mo (monitor speaker has come unglued from the top of the case)
[15:44] <jcoxon> okay
[15:46] <jcoxon> well now to look into an antenna solution
[15:46] <neontube> i found a design for a home made one yesterday
[15:47] <jcoxon> oh cool
[15:47] <jcoxon> do you have a link?
[15:48] <neontube> gimmy a min, got hot glue gun all over the place

[15:57] <jcoxon> neontube, that looks suprisingly simple
[15:57] <neontube> indeed
[15:58] <jcoxon> have you managed to download any pictures yet?
[16:01] <neontube> nar, i recon the sound card on the laptop is sh*t
[16:02] <neontube> found a button about half way through a capture yesterday called 'mic boost'
[16:02] <neontube> and that was making loads of noise with it on
[16:02] <neontube> might hook up a pc later and use a line in insted
[16:03] <jcoxon> basically its about getting the noise down as much as possible?
[16:03] <neontube> think so
[16:03] <neontube> short leads
[16:03] <neontube> all unneeded electrical gear thats in the house / flat turned off etc
[16:03] <neontube> the guy on that link did a capture witha cheap hand held scanner
[16:04] <jcoxon> not bad to tell you the truth
[16:10] <jcoxon> i can't believe i'm struggling with a 555 timer circuit
[16:11] <neontube> oh dear
[16:12] <neontube> lol i got anoyed at one a year or 2 ago, gave up and used an 8pin pic and set the timming i wanted in software
[16:12] <jcoxon> haha
[16:13] <neontube> back in a bit
[16:13] <neontube> going to check on dinner
[16:17] <mc-> jcoxon, what you trying to do with the 555?
[16:21] <jcoxon> oh just make a 1hz pulse
[16:22] <jcoxon> basically it'll be attached to my morse transmitter
[16:22] <jcoxon> the gm862 will pull it to ground to transmit
[16:22] <jcoxon> but otherwise it'll do a 1hz pulse
[16:22] <jcoxon> actually the gm862 will put the reset line high
[16:22] <jcoxon> no low
[16:22] <jcoxon> yeah its low
[16:28] <mc-> I think you need a pullup on the 555 output line

[18:26] <jcoxon> hey neontube
[18:33] <neontube> what u up to
[18:37] <neontube> grrrr why do they put torx screws in products!
[18:38] <neontube> i've got a sky remote thats being a bit rubbish, u have to press the rubber keys fairly hard, all it needs is a clean and its good as new... but they have put realy small torx screws in it and i've not got one that will fit
[18:39] <jcoxon> sky remotes are really rubbish
[18:39] <jcoxon> sure its not hte batteries?
[18:39] <neontube> they are new
[18:40] <jcoxon> then its a matter of opening it up
[18:40] <neontube> its only the bottom few keys
[18:40] <neontube> yup
[18:41] <neontube> like the 0 key, which is anoying when the dumb 'watershed' pin code request comes up for films... and lets face it, 0000 is the only pin i won't forget !
[18:41] <jcoxon> haha
[18:41] <jcoxon> on sky its usually the last 4 digits of your sky card
[18:41] <neontube> yer i changed it
[18:41] <jcoxon> well ours is
[18:41] <jcoxon> :-p
[18:41] <neontube> i've got 2 boxes
[18:42] <neontube> so changed them to the same
[18:42] <jcoxon> right
[18:42] <neontube> 2 sky plus boxes now :D
[18:42] <jcoxon> record 4 tv shows then
[18:42] <neontube> so no argument over what i can record
[18:42] <neontube> plus the 90cm dish and motor
[18:43] <neontube> and the reciver thats connected to
[18:43] <neontube> its got 5000 channel memory, and it filled it on the first few satelites it found
[18:44] <edmoore> you'd do well to get some torx no 6 and 5 inserts
[18:44] <edmoore> nokia phones use them aswell
[18:44] <neontube> yer i did have one, but it got rounded off realy easily
[18:44] <neontube> after the 6th time i ground the tip down it was bin fodder
[18:46] <neontube> will have to pick up some new ones next week if i can sneek off from this work thing for an hour or so
[18:49] <neontube> anyway

[21:24] <Professor> that's what I meant
[21:24] <Professor> I'm building a 23cm band microwave power amp
[21:25] <Professor> 200-300 watt class
[21:25] <Professor> that's the resonant cavity for the output stage
[21:25] <neontube> sweet
[21:25] <neontube> i've half built one made of mdf thats good for cutting pcbs and stuff likte that
[21:26] <Professor> ah, I woudln't ever do this with pcb's
[21:26] <neontube> but can't cut alloy like that
[21:26] <Professor> it's so hard on the machine, takes way longer than just etching, and costs more than sending out
[21:27] <neontube> i havn't done any high frequency work in ages
[21:27] <Professor> this is new to me
[21:27] <neontube> i used to work for agilent technologies (used to be part of HP)
[21:28] <neontube> they make all the test and measurement gear
[21:28] <Professor> right on, I have a sweet agilent 8712ES network analyzer
[21:28] <Professor> hehe
[21:28] <Professor> (and a ton of other shit)
[21:28] <neontube> i used to work for the phase noise expert
[21:28] <neontube> now that is wierd s**t
[21:29] <neontube> how old is that analyzer ?
[21:29] <neontube> (i've lost track with the model numbers over the years since i left there)
[21:32] <Professor> eh, I dunno, several years
[21:32] <Professor> I bought it used
[21:32] <Professor> I can still get about $14k for it
[21:32] <neontube> not the windows based one then ?
[21:32] <Professor> I have a much older one that does DC - 30MHz
[21:32] <Professor> no, not windows based
[21:33] <Professor> well, 5Hz to 30MHz or so
[21:33] <Professor> with the s-param test set
[21:33] <neontube> cool
[21:33] <Professor> it has its uses. my main one has been on loan to the local lab
[21:33] <Professor> guess they don't have funding for their own shit, heh
[21:33] <neontube> i was a technical logistics monkey when i worked for them on a year out from uni
[21:33] <Professor> cool
[21:34] <neontube> used to have to set up demo equipment and have it shipped to the customers site for sales demo or training needs anywhere on the plannet
[21:34] <neontube> the phase noise stuff used to fill a large transit van when it was in its packing cases
[21:34] <Professor> nice
[21:35] <neontube> lol no, heavy and anoying ! not nice
[21:35] <neontube> but i did get to meet a load of cool customers
[21:35] <neontube> i went to one for a few days when we sold them a fairly basic spec anlyzer
[21:35] <neontube> but they worked above the pro drive rally company
[21:36] <neontube> and they made te gps tracking boxes used on the rally cars for all of the world rally champ cars

[21:37] <Professor> nice
[21:37] <Professor> pretty cool stuff
[21:37] <neontube> yup yup
[21:38] <neontube> i would of loved to go back and work for them
[21:38] <neontube> but as with alot of companys they hit hard in 2001 and lost abot 1/3rd of there work forse
[21:39] <neontube> anyway
[21:39] <neontube> i'm going offline now
[21:39] <neontube> 2 weeks off, back to work tommorow :-(
[21:39] <neontube> got to load all the tools back in the car
[21:39] <neontube> night all

[22:29] <jcoxon> evening all
[22:32] edmoore (n=edmoore@88.212.167.121) joined #highaltitude.
[22:32] <jcoxon> just watched the film sunshine, it was nearly an amazing scifi film till the twist

[22:41] <edmoore> lo all
[22:41] <edmoore> ooooh rain man
[22:41] <edmoore> jcoxon: what is sunshine aboot?
[22:44] <jcoxon> about these space mission to 'restart' the sun
[22:44] <jcoxon> its actually suprisingly good
[22:44] <jcoxon> perhaps not that scientificly accurate
[22:45] <edmoore> :)
[22:45] <edmoore> have you ever seen 'the core'?
[22:45] <jcoxon> but it explores the crews relationships
[22:45] <jcoxon> oh its better then the core
[22:45] <edmoore> the core had me crying
[22:46] <jcoxon> nah sunshine is good, it looks incredible
[22:46] <jcoxon> just it scews it up at the end
[22:46] <jcoxon> but i'll let you watch it :-)
[22:47] <edmoore> :)
[22:47] <edmoore> I've never seen rain man before, but I'm delighted to see that it's on
[22:48] <jcoxon> is it on now?
[22:49] <edmoore> nope, in a bit
[22:49] <edmoore> as soon as gladiator finishes on 4
[22:49] <edmoore> until then, family guy
[22:50] <jcoxon> even better
[22:51] <edmoore> awesome evening in :)
[23:07] <edmoore> jcoxon: do the telit modules get a network lock pretty quickly?
[23:08] <edmoore> i'm wondering whether or not to turn it off between sms's to save power
[23:11] <jcoxon> ummm they should do
[23:11] <jcoxon> i've never pushed it to tell you the truth
[23:11] <jcoxon> within 5 seconds
[23:11] <jcoxon> they have a powersave mode i think
[23:11] <jcoxon> give me one sec
[23:12] <edmoore> oh yes, 3ma
[23:12] <edmoore> may aswell leave it on standby for the most part
[23:12] <jcoxon> ther eis a whole section in the software manual
[23:15] <jcoxon> hahahaha
[23:15] <jcoxon> redneck topgun
[23:16] <edmoore> love it :)
[23:17] <edmoore> random starwars reference
[23:23] <edmoore> do you need any of the suprious serial port pins like flow controls?
[23:24] <jcoxon> nah
[23:24] <jcoxon> but
[23:24] <jcoxon> the DTR line is used to distinguish if you want AT commands or python script thingy
[23:25] <edmoore> what's the seperate python debug port for then?
[23:26] <jcoxon> oh thats where print strings get sent
[23:26] <edmoore> ok
[23:27] <edmoore> i'll wire it in
[23:28] <jcoxon> :-)
[23:28] <edmoore> data carrier detect - is that when there's network coverage? If you want me to check manual instead just say, but you're a bit quicker :)
[23:28] <jcoxon> yeah make it accessible, debuging blind is hard
[23:28] <jcoxon> edmoore, best check the manual
[23:28] <jcoxon> all i do is check it
[23:28] <edmoore> i will do
[23:28] <edmoore> i think I'll connect the lot
[23:28] <edmoore> may aswell
[23:30] <jcoxon> probably best
[23:32] <edmoore> two pints live!
[23:32] <jcoxon> i know, i'm very excited
[23:32] <edmoore> £5 says it won't be on the air any longer by the end of the year
[23:33] <jcoxon> right, made my 555 based pulse thingy circuit
[23:36] <edmoore> coolio
[23:45] <jcoxon> sadly going to miss rain man
[23:45] <jcoxon> have to get up at a reasonable hour tomorrow
[23:45] <edmoore> :(
[23:46] <jcoxon> have a crazy week of finishing a project and exams on friday
[23:46] <edmoore> such is life
[23:46] <jcoxon> today was my calm before the storm
[23:46] <jcoxon> i have one question
[23:46] <edmoore> shoot]
[23:46] <jcoxon> diodes
[23:47] <edmoore> good question
[23:47] <jcoxon> i need some as i'm going to have two routes going into the radio
[23:47] <jcoxon> one from the gm862 and the other the 555 thingy
[23:47] <edmoore> uhuh
[23:48] <jcoxon> (the gm862 will hold the 555 in reset when it transmits
[23:48] <jcoxon> )
[23:48] <jcoxon> so i guess i need diodes to stop the 555 sent power into the gm862
[23:48] <jcoxon> and vice versa
[23:48] <edmoore> it might be ok if it's just gpio
[23:48] <edmoore> well, ignore that actually
[23:48] <edmoore> load of rubbish
[23:48] <edmoore> no, infact not rubbish
[23:49] <jcoxon> its probably fine
[23:49] <jcoxon> but
[23:49] <edmoore> just a couple or biggish resistors on the outputs of each would be fine
[23:49] <jcoxon> not diodes?
[23:49] <edmoore> and you probably don't want the 0.7V drop into the vco of the radio... unless you do want that drop
[23:49] <edmoore> well i assume the output of a 555 is low when reset
[23:49] <jcoxon> yup
[23:50] <edmoore> which means it's connected to ground. that would short the gm862 output pin when it was high
[23:50] <edmoore> but if you have, say, a 10k resistor on the pin, it'd be fine
[23:50] <edmoore> diods would be fine too if the voltage drop isn't a problem
[23:51] <jcoxon> the manual says that the radio module expects vcc for high
[23:51] <edmoore> ok, well both would be fine then I spose
[23:52] <jcoxon> really
[23:52] <jcoxon> vcc is 3.8v
[23:52] <edmoore> 3.1V *should* be high enough
[23:52] <jcoxon> but actually the module drops it to 2.2v
[23:52] <edmoore> but hey, go with resistors and then it'll be fine
[23:52] RocketBoy (n=grunge@217.47.75.27) left irc: "Leaving"
[23:53] <jcoxon> okay so 10k resistor between each line into the data line of the radio should be okay
[23:53] <edmoore> yep
[23:53] <jcoxon> cool
[23:57] <jcoxon> night
