[00:00] <macfreak4> Westminster is the name of my school
[00:00] <jcoxon> ooo cool
[00:00] Action: jcoxon knows another ANSWER balloon project
[00:00] <jcoxon> :(
[00:00] <macfreak4> WHAT
[00:00] <macfreak4> I searched google for one!
[00:00] <jcoxon> http://www.freewebs.com/answer1/index.htm
[00:00] <macfreak4> do you have a link?
[00:00] <jcoxon> its uk based
[00:00] <jcoxon> it'll be fine
[00:01] <macfreak4> but it takes away from the uniqueness
[00:02] <macfreak4> now i'm upset
[00:02] <macfreak4> >:o
[00:03] <macfreak4> damn it
[00:04] <jcoxon> :( sorry
[00:04] <macfreak4> not your fault
[00:04] <macfreak4> its just that the name worked so well
[00:06] <jcoxon> i'm sure you'll think of something else
[00:07] <jcoxon> right i'm sorry macfreak4 but i'm going to have to go to bed
[00:07] <jcoxon> if i think of a good name i'll email you tomorrow
[00:07] <jcoxon> night

[00:24] <macfreak4> hi
[00:25] <defy> hey
[00:25] <macfreak4> my name doesnt work :(
[00:26] <macfreak4> someone else got it first
[00:26] <defy> doh
[00:26] <defy> for the same type of project?
[00:26] <macfreak4> yeah
[00:26] <macfreak4> looks like he/she/they just started
[00:26] <defy> damn, what are the chances, lol
[00:26] <macfreak4> I KNOW!!!
[00:26] <macfreak4> ugh
[00:26] <macfreak4> so mad
[00:26] <macfreak4> lol
[00:26] <macfreak4> http://www.freewebs.com/answer1/index.htm
[00:27] <defy> interesting
[00:28] <macfreak4> yea
[00:44] <macfreak4> g2g
[00:44] <macfreak4> dinner
[00:59] <defy> :)
[01:11] <macfreak4> back
[01:48] <macfreak4> yay
[01:48] <macfreak4> the beeper circuit is built
[01:48] <macfreak4> now time to test...
[01:58] <defy> cool
[02:11] <macfreak4> ugh
[02:11] <macfreak4> something was wrong with that schematic.
[02:12] <macfreak4> now i'm having to try another
[02:34] <macfreak4> hehehe
[02:34] <macfreak4> it lives!
[02:44] <macfreak4> d'oh!
[02:44] <macfreak4> fried it
[02:44] <macfreak4> :(
[02:49] <macfreak4> it worked, but then i thought
[02:49] <macfreak4> "hmm, what if i tried a bigger speaker?"
[02:49] <macfreak4> and the bigger speaker worked for a couple seconds, but then pulled too much current and fried it
[02:54] <defy> doh
[02:54] <defy> that sucks, easy to make again?
[03:06] <macfreak4> yeah
[03:06] <macfreak4> luckily i built it on a solderless breadboard
[03:06] <macfreak4> which means i don't have to do any soldering
[03:06] <macfreak4> and the 556 integrated circuit, which is what i fried, is less than 2 bucks at RadioShack
[03:06] <macfreak4> so not too big a loss
[03:06] <macfreak4> ;)
[03:27] <defy> sweet
[03:30] <macfreak4> wow
[03:30] <macfreak4> i just organized 500 resistors
[03:31] <macfreak4> in 45 mins
[03:31] <macfreak4> heh
[04:35] <macfreak4> well night

[19:45] <Tiger^> hi, jcoxon
[19:48] <jcoxon> hey Tiger^
[19:51] <Tiger^> my balloon has arrived today
[19:52] <Tiger^> and apparently nobody tested the package for illegal drugs, with a needle ;)
[19:52] <Tiger^> so it's in one piece
[19:52] <jcoxon> haha
[19:52] <jcoxon> where did you order it from?
[19:52] <Tiger^> Kaymont
[19:52] <jcoxon> oh right
[19:53] <jcoxon> they never respond to my emails :(
[19:53] <Tiger^> yeah you know
[19:53] <Tiger^> it takes a bit of expertise ;P
[19:53] <jcoxon> hehe
[19:53] <Tiger^> i had to remind them a couple of times
[19:54] <Tiger^> to process my order
[19:54] <Tiger^> and finally
[19:54] <Tiger^> they shipped it to the billing address
[19:54] <Tiger^> not to the shipping address
[19:55] <Tiger^> though i made it ultra damn clear which was which
[19:56] <jcoxon> i've still got 3 balloons in my draw
[19:56] <Tiger^> great
[19:56] <jcoxon> my lithiums arrived today :-D
[19:57] <Tiger^> :)
[19:58] <Tiger^> and both my GPSes should arrive tomorrow
[19:58] <Tiger^> a Garmin GPS-35 for the payload
[19:58] <Tiger^> and a bluetooth gps for ground tracking
[20:01] <jcoxon> cool
[20:01] <jcoxon> so nearly ready!
[20:01] <jcoxon> will be back in a sec

[20:12] <Tiger^> hmm, not nearly :(
[20:13] <jcoxon> ?
[20:13] <Tiger^> the pcb house is lagging behind
[20:13] <jcoxon> oh
[20:14] <jcoxon> i've just got my case to get and permission
[20:14] <jcoxon> oh and helium
[20:18] <jcoxon> when are you planning to launch?
[20:18] <jcoxon> (i've got a terrible memory)
[20:18] <Tiger^> may 30th
[20:18] <Tiger^> so i've got little more than two weeks
[20:19] <Tiger^> it's not as bad with the permission as i thought it'd be
[20:20] <Tiger^> but it's bad
[20:20] <jcoxon> oh dear
[20:20] <jcoxon> it'll all be fine
[20:20] <jcoxon> permission here is quite easy - just takes 28 days
[20:20] <jcoxon> though they do warn you
[20:20] <Tiger^> yeah, and theoretically here you can get one overnight
[20:21] <Tiger^> but try to talk to polish authorities... ;>
[20:21] <jcoxon> hehe
[20:21] <jcoxon> don't plan to yet
[20:22] <jcoxon> though will one day launch a balloon to you
[20:22] Action: jcoxon has been thinking big
[20:22] <Tiger^> wow
[20:22] <Tiger^> you mean a steerable balloon?
[20:22] <jcoxon> well :-D
[20:22] <jcoxon> would be interesting
[20:22] <Tiger^> yeah :)
[20:22] <jcoxon> depends exactly how the stratosphere effects a balloon for long duration
[20:23] <jcoxon> it might not require that must energy to move it
[20:23] <jcoxon> solar panels
[20:23] <jcoxon> must -> much
[20:23] <Tiger^> hmm, the national weather service here launches long duration flights sometimes
[20:24] <Tiger^> they use zero pressure balloons or something like that
[20:24] <jcoxon> i'll be launching long duration zero pressure this summer in africa
[20:24] <Tiger^> gosh, you're really thinking big
[20:24] <Tiger^> ;)
[20:25] <jcoxon> oh i'm working with CNES
[20:25] <jcoxon> i'm jsut helping out
[20:25] <jcoxon> but for the rest of the summer i'll be in cambridge working on a long duration high altitude platform
[20:26] <Tiger^> nice
[20:26] <jcoxon> but if we can make it stay in one place whats to stop us making it move
[20:26] <Tiger^> right
[20:27] <Tiger^> most important problems should be power and propulsion
[20:27] <jcoxon> maintain altitude is the really issue
[20:27] <jcoxon> and communication
[20:27] <Tiger^> well maintaing altitude shouldn't be so hard with a zero pressure balloon?
[20:28] <Tiger^> and comm... yeah it's going to be a problem with UK law
[20:28] <jcoxon> oh it won't be zero pressure
[20:28] <jcoxon> hehe i'm doing two things this summer
[20:28] <jcoxon> 2 weeks in africa with zero pressure
[20:28] <jcoxon> and then 8 weeks in cambridge working on the high altitude platform
[20:29] <Tiger^> ah
[20:29] <Tiger^> so what about comm?
[20:29] <Tiger^> iridum phones, maybe?
[20:29] <jcoxon> radio modems
[20:29] <jcoxon> i've found some OEM 20mile ones
[20:30] <jcoxon> but will have to experiment
[20:30] <Tiger^> are you allowed to send them up?
[20:30] <jcoxon> think so
[20:30] <Tiger^> hmm
[20:30] <Tiger^> weird
[20:30] <jcoxon> will definitly consult the relavent laws
[20:30] <Tiger^> yeah
[20:30] Action: jcoxon has to pass his exams first :-D
[20:30] <Tiger^> but it's really weird
[20:30] <Tiger^> you can send a radio modem
[20:31] <Tiger^> but you can't send a radio + a modem
[20:31] <jcoxon> different freq
[20:31] <jcoxon> and the Ham laws are archaic
[20:31] <Tiger^> oh, that restrictions only apply to ham bands?
[20:32] <jcoxon> oh yes
[20:32] <jcoxon> well
[20:32] <jcoxon> no
[20:32] <jcoxon> CB as well
[20:32] <jcoxon> most freqs actually
[20:32] <jcoxon> but i think radio modems are allowed
[20:32] <jcoxon> on particular freqs
[20:34] <Tiger^> great
