[00:00] <Tiger^> so you're going to use 70cm band?
[00:00] <macfreak4> ya
[00:01] <macfreak4> like freespace
[00:01] <macfreak4> only with a j-pole instead of an eggbeater antena
[00:01] <macfreak4> antenna*
[00:01] <Tiger^> yeah, i'll use a j-pole too
[00:01] <macfreak4> are you using the mobile phone method?
[00:01] <macfreak4> oh
[00:01] <macfreak4> lol
[00:01] <macfreak4> typed before i read :(
[00:01] <Tiger^> and a phone as a backup
[00:02] <macfreak4> o ok
[00:02] <macfreak4> i was considering that too, but my budget is a bit tight...
[00:04] <Tiger^> yeah, this balloon business tends to get expensive ;>
[00:06] <macfreak4> ya
[00:07] <macfreak4> tho i imagine once a near spacecraft system is established, each launch only costs batteries, a balloon, and helium
[00:07] <macfreak4> + costs for damages to the near spacecraft
[00:16] <Tiger^> yeah
[00:17] <macfreak4> i dont plan on doing that tho
[00:17] <Tiger^> damage?
[00:17] <Tiger^> ;)
[00:19] <macfreak4> no
[00:19] <macfreak4> establishing a near spacecraft system
[00:20] <macfreak4> this will be my first and probably last flight
[00:20] <macfreak4> i usually dont stick to one specific area of electronics/computers
[00:20] <Tiger^> oh
[00:21] <macfreak4> wanna see a little bit of everything, before i get bored ;)
[00:21] <Tiger^> hmm, i'm thinking 'bout sending a second one up
[00:21] <Tiger^> this time with a Linux box onboard
[00:21] <macfreak4> oh
[00:22] <macfreak4> yea i feel bad about sending Win 98 up
[00:22] <macfreak4> but my hardware does not permit
[00:22] <Tiger^> hehe
[00:22] <Tiger^> after the second flight i'll probably quit
[00:22] <macfreak4> yea and its really expensive, too, even if all you're paying for is latex and gas
[00:22] <Tiger^> yeah
[00:23] <Tiger^> esp. gas is expensive
[00:23] <macfreak4> well i found a REALLY good place to get helium here
[00:23] <Tiger^> lucky you
[00:24] <macfreak4> there's a woman with a home business selling helium (in a rented tank) at $55 for 295 cubic feet tanks
[00:24] <Tiger^> nice!
[00:24] <Tiger^> really nice
[00:25] <Tiger^> i'll have to pay almost three times that
[00:25] <Tiger^> as i have to get it from a commercial supplier
[00:25] <Tiger^> that does high volume orders
[00:25] <macfreak4> oh :(
[00:25] <macfreak4> well you win some and you lose some
[00:25] <Tiger^> yeah
[00:25] <macfreak4> the other places i called didnt even know what cubic feet is
[00:26] <Tiger^> hehe
[00:26] <Tiger^> they said they don't put their feet in no cubes?
[00:26] <macfreak4> they said "our tanks fill 200 party balloons and it costs 75$ to rent plus a 100$ deposit"
[00:26] <macfreak4> lol
[00:26] <Tiger^> hehe
[00:26] <macfreak4> are you buying your balloon from ebay or kaymont?
[00:27] <Tiger^> kaymont
[00:27] <macfreak4> oh
[00:27] <macfreak4> what size?
[00:27] <Tiger^> 1500 :)
[00:27] <macfreak4> have you bought it already?
[00:27] <Tiger^> yeah
[00:27] <macfreak4> how much did it cost?
[00:27] <Tiger^> http://moo.pl/~tygrys/junk/bal/8.html
[00:27] <Tiger^> ;)
[00:28] <Tiger^> $90
[00:28] <macfreak4> oh well b/c i just bought a 1200g balloon for 65$ w/ shipping and was wondering how much more it would have cost for a larger one...
[00:28] <macfreak4> from kaymont, that is
[00:28] <macfreak4> directly
[00:28] <Tiger^> you bought it on ebay?
[00:28] <macfreak4> no
[00:28] <macfreak4> from kaymon
[00:28] <macfreak4> kaymont*
[00:28] <Tiger^> oh
[00:29] <Tiger^> apparently a 1200g is most cost effective
[00:29] <macfreak4> yea i think its most commonly used...
[00:30] <macfreak4> i was surprised when i called b/c they told me it would cost 80$ over email but on the phone they said 65$
[00:30] <macfreak4> go figure
[00:30] <macfreak4> :P
[00:30] <Tiger^> hmm
[00:30] <Tiger^> yeah, you know
[00:30] <Tiger^> the guy that did Balloon v1.0
[00:30] <Tiger^> bought a 1500g for $60
[00:31] <macfreak4> well mine's 65$ incl. shipping
[00:31] <Tiger^> they just can't decide ;)
[00:31] <macfreak4> yeah i think their prices fluctuate
[00:31] <Tiger^> yeah and you know what?
[00:31] <Tiger^> i'm thinking conspiracy ;>
[00:31] <macfreak4> and balloon v1.0 was a little while ago
[00:31] <macfreak4> a conspiracy theory!
[00:31] <Tiger^> yeah
[00:31] <macfreak4> quickly spread it over the web!
[00:31] <Tiger^> 'cause when i called the national weather service here in poland
[00:31] <macfreak4> haha
[00:31] <Tiger^> they told me they get their balloons either from kaymont or from a japanese supplier
[00:32] <macfreak4> oh
[00:32] <Tiger^> and if you look at that picture
[00:32] <Tiger^> there's "Japan" printed
[00:32] <Tiger^> on that label
[00:32] <macfreak4> oh you're right
[00:32] <Tiger^> ;)
[00:32] <macfreak4> ha!
[00:33] <Tiger^> i've read that there are really only two or three factories in the world making these balloons
[00:33] <Tiger^> one is kaymont's, the second is in the US too and the third is japanese
[00:33] <Tiger^> but if kaymont gets them from Japan... well...
[00:34] <Tiger^> *evil grin*
[00:34] <macfreak4> lol
[00:34] <macfreak4> they might share use of factories
[00:34] <Tiger^> yeah
[00:34] <Tiger^> they're conspiring!
[00:34] <Tiger^> ;>
[00:34] <Tiger^> lol
[00:34] <macfreak4> hey you like 2010 and the terminator
[00:34] <macfreak4> me too
[00:34] <macfreak4> lol
[00:34] <macfreak4> *just saw that*
[00:34] <Tiger^> hehe
[00:34] <Tiger^> yeah
[00:35] <macfreak4> the blog is a link to localhost, tho
[00:35] <macfreak4> ;)
[00:36] <Tiger^> oh, yeah, i've quit blogging years ago
[00:36] <macfreak4> waste of time?
[00:36] <Tiger^> and the site is sooo outdated
[00:36] <Tiger^> yeah :)
[00:36] <macfreak4> yea i dont like blogs either
[00:37] <macfreak4> ok i came up with a new name, since ANSWER is taken
[00:37] <macfreak4> E.N.S.U.R.E.
[00:37] <Tiger^> huh
[00:37] <macfreak4> Electronic Near Space Utility for Recovery and Experimentation
[00:38] <macfreak4> for my balloon
[00:38] <macfreak4> :D
[00:38] <Tiger^> :)
[00:38] <Tiger^> you know, you should try and use the toy cyborgizer
[00:38] <macfreak4> ?
[00:39] <Tiger^> oh, it's broken now
[00:39] <macfreak4> wut?
[00:39] <Tiger^> http://www.brunching.com/toys/toy-cyborger.html
[00:39] <Tiger^> it's a web script
[00:39] <Tiger^> that finds hi-tech acronyms
[00:39] <Tiger^> for a given name ;)
[00:40] <Tiger^> they're rather scary sounding ;)
[00:40] <macfreak4> uh what
[00:40] <macfreak4> you gave me a link to "CASH COW DOW"
[00:40] <Tiger^> hm
[00:40] <Tiger^> i told you it was broken
[00:40] <macfreak4> o now it went through
[00:41] <macfreak4> thats so weird
[00:41] <macfreak4> but it doesnt exist
[00:41] <macfreak4> yea
[00:41] <Tiger^> it's something wrong with their php scripts
[00:41] <macfreak4> yea
[00:47] <Tiger^> ok
[00:48] <Tiger^> time to sleep
[00:48] <Tiger^> bye :)

[20:59] <macfreak4> hi
[21:30] <macfreak4> well nichrome wire can definitely cut nylon rope ;)
[21:30] <Tiger^> hi guys
[21:30] <Tiger^> yeah
[21:30] <Tiger^> works nicely doesn't it
[21:30] <macfreak4> oh yeah!
[21:31] <macfreak4> i got really thin wire (.0031 inches thick) because my relays can't handle high currents
[21:31] <macfreak4> but even so this thin wire glows red hot
[21:31] <macfreak4> hehe
[21:31] <Tiger^> :)
[21:31] <Tiger^> i used mosfets
[21:31] <Tiger^> no moving parts that can freeze
[21:31] <macfreak4> the interior shouldn't get very cold
[21:32] <macfreak4> remember, its giving off 10 watts + of heat!
[21:32] <macfreak4> the laptop, that is
[21:32] <Tiger^> hm, your cutdown is inside the main payload box?
[21:32] <macfreak4> uh the relay is
[21:32] <Tiger^> ah
[21:32] <Tiger^> right
[21:32] <macfreak4> ya
[21:32] <macfreak4> no nichrome in the payload would be bad
[21:32] <macfreak4> hehe
[21:32] <Tiger^> though i've tested my styrofoam
[21:33] <Tiger^> it will melt
[21:33] <macfreak4> ya thats how i cut holes
[21:33] <macfreak4> with a crappy old soldering iron i never use
[21:33] <Tiger^> it will light, if the flame's hot enough
[21:33] <Tiger^> but it will not support combustion
[21:34] <Tiger^> so it's a non-issue at high altitude with almost no oxygen :)
[21:34] <macfreak4> oh
[21:34] <macfreak4> well ive found that the rope has to have tension in it
[21:35] <macfreak4> otherwise what is cut cools down again and it doesn't break
[21:35] <macfreak4> lol
[21:35] <macfreak4> but thats not a problem, since if the payload is still attached to the balloon it will have tension no matter what
[21:35] <Tiger^> yeah
[21:35] <Tiger^> i've looped the rope around the cutdown
[21:36] <Tiger^> so there's always tension
[21:39] <macfreak4> how thick is your wire?
[21:39] <macfreak4> b/c this stuff looks like fishing line it's soo thin
[21:41] <Tiger^> 1mm
[21:41] <Tiger^> it's at about 1.39 ohm
[21:42] <Tiger^> i could have used 0.5mm, but it's 5.50 ohm
[21:43] <Tiger^> i'm even considering 1.5mm, which is 0.75 ohm
[21:43] <Tiger^> i want to get as large a current as possible
[22:23] <macfreak4> oh lol
[22:23] <macfreak4> this is about 50 ohms per foot
[22:26] <Tiger^> hmm
[22:26] <Tiger^> so 100mA at 5V
[22:27] <macfreak4> well
[22:27] <macfreak4> if i used a foot
[22:28] <macfreak4> which i won't
[22:29] <macfreak4> probably 2 or 3 inches
[22:29] <macfreak4> so
[22:29] <macfreak4> around 10 ohms
[22:31] <Tiger^> yeah
