[00:05] <natrium42> robert and james have been working on it -- it sends positions to the distributed listening system
[00:06] <natrium42> kinda like custom APRS
[00:06] <natrium42> worked great the past two launches :)
[00:06] <fergusnoble> ok, thats quite sweet
[00:06] <natrium42> yeah
[00:07] <natrium42> robert just added checksum, so we should see less buggy positions
[00:07] <fergusnoble> oh cool, has he documented the checksum format?
[00:08] <natrium42> yeah, it's on the wiki
[00:08] <natrium42> it's just xoring all bytes atm
[00:08] <natrium42> i'd go with CRC16
[00:09] <natrium42> with pure xoring, errors can cancel each other out
[00:09] <natrium42> need some bit shuffling too
[00:09] <natrium42> but it's definitely a big improvement
[00:16] <fergusnoble> cant seem to find it..
[00:16] <fergusnoble> sorry, just found it
[00:17] <natrium42> oh, alright

[00:20] <Laurenceb> hows it going?

[00:27] <Laurenceb> did they go well?

[14:03] <rjharrison_work> Fine fime
[14:03] <rjharrison_work> Been playing a bit with the distributed listener
[14:03] <fergusnoble> yeah it look good!
[14:03] <rjharrison_work> and made a mobile web page for iphone tracking
[14:03] <fergusnoble> i hear youve made a version of fldigi with it integrated?
[14:04] <fergusnoble> oh neat

[14:05] <rjharrison_work> Yep me and james have been working on it
[14:05] <rjharrison_work> It when you select the payload it auto configures fldigi to the right settings for reception
[14:05] <rjharrison_work> http://www.robertharrison.org/mobile.php
[14:05] <rjharrison_work> This is the mobie version
[14:06] <rjharrison_work> I hve just posted some data to it
[14:07] <rjharrison_work> If you click the coords it takes you to google maps or the map app if you have an I phone
[14:07] <fergusnoble> thats really nice
[14:08] <fergusnoble> natrium said you have come up with a checksum format
[14:08] <fergusnoble> ill try and implement that on badger soon
[14:12] <fergusnoble> im working on getting the landing prediction code packaged up into a neater commandline tool atm
[14:12] <fergusnoble> so it should be easier to integrate with the tracker if you wanted to
[14:13] <rjharrison_work> Cool
[14:24] <rjharrison_work> fergusnoble: The code to do it is here http://wiki.ukhas.org.uk/projects:dlistener
[14:24] <fergusnoble> ok thanks
[14:24] <rjharrison_work> I put it in the icarus s/w the other day

[21:42] <SpeedEvil> sbasuita: self-defence is legal in most any jurisdiction
[21:44] <gordonjcp> sbasuita: nope
[21:44] <gordonjcp> not if you're in international waters
[21:44] <gordonjcp> once you're properly out, you can string 'em up from the yardarm
[21:45] <gordonjcp> saves a lot of time, that
[21:45] <sbasuita> Just read the article, is all. Seems very well written.
[21:45] <DanielRichman> gordonjcp, fair enough, but the MPs expenses were 'legal'. (Not that I care about that issue, I add, just using it as an example) But the media and public are going mad about it
[21:45] <DanielRichman> Soon as it gets out that you're shooting pirates for fun
[21:45] <sbasuita> "Piracy is considered an offense of universal jurisdiction, such that any state may board and seize a ship engaged in piracy, and any state may try a pirate and impose sanctions according to that state's own law."
[21:45] <DanielRichman> You'll have hoards of christians on you for starters
[21:45] <gordonjcp> DanielRichman: meh
[21:46] <gordonjcp> DanielRichman: get them on a boat, get into international waters, and have at it
[21:46] <sbasuita> DanielRichman, this is a matter of legality not morality
[21:46] <DanielRichman> sbasuita, yes but you won't last long, will you
[21:46] <gordonjcp> DanielRichman: no sane jury would convict
[21:46] <natrium42> sbasuita, so when's launch? :)
[21:46] <DanielRichman> Think about it
[21:46] <sbasuita> natrium42, asap
[21:46] <natrium42> yay
[21:46] <DanielRichman> Obama would speak out against you
[21:46] <DanielRichman> natrium42, I'm currently in the process of fabricating our PCB
[21:46] <sbasuita> natrium42, as soon as we've sourced 1/8 inch diameter copper rod
[21:46] <natrium42> you are etching it?
[21:46] <DanielRichman> natrium42, chemical process ftw :)
[21:46] <natrium42> hehe
[21:46] <DanielRichman> bigass tracks are used to try and minimise failures
[21:47] <sbasuita> DanielRichman, 'fabricating' - you make the school sound so up-market
[21:47] <DanielRichman> sbasuita, that's the technical term
[21:47] <DanielRichman> in reality, it's dunking a piece of plastic in some pongey chemicals
[21:47] <natrium42> my etching setup --> http://natrium42.com/gallery2/v/misc/IMG_0620.JPG.html
[21:47] <DanielRichman> oh, there's the bubble machine too!
[21:48] <DanielRichman> natrium42, are you a UV or toner transfer person?
[21:48] <natrium42> tried both
[21:48] <natrium42> i use toner when traces are not too thin
[21:48] <natrium42> but dunno, lately i prefer PCBs made
[21:49] <natrium42> since it's very hard to do double layers yourself
[21:49] <DanielRichman> naturally
[21:49] <DanielRichman> THP is a bitch.
[21:49] <DanielRichman> luckily our pcb is single sided
[21:49] <DanielRichman> with no flywires! :D
[21:49] <natrium42> cool, that's always good
[21:49] <DanielRichman> took two goes manually routing to get it perfect
[21:50] <natrium42> :)
[21:50] <natrium42> manual routing is where it's at
[21:52] <sbasuita> http://pastebin.ca/1448006
[21:52] <DanielRichman> The problem is that when you do it manually you tweak the location of the components too
[21:52] <sbasuita> full of bugs but meh
[21:52] <DanielRichman> autorouter can't do that
[21:52] <DanielRichman> sbasuita, did you make this?
[21:52] <sbasuita> DanielRichman, yes
[21:52] <DanielRichman> Nice!
[21:52] <DanielRichman> sbasuita, you need to get herabot able to play MAFIA
[21:52] <DanielRichman> or I might make an AJAX version
[21:53] <sbasuita> DanielRichman, never played mafia
[21:53] <sbasuita> bugs:
[21:53] <sbasuita> 1) stay away from the corners
[21:54] <sbasuita> 2) food appears under snake, goes invisible
[21:54] <sbasuita> 3) movement happens one step after it should
[21:54] <sbasuita> but yeh i'll work on it tomorrow
[22:00] <DanielRichman> How do I speed this thing up?
[22:00] <DanielRichman> sbasuita, if I press a key the snake freeses
[22:00] <DanielRichman> ie
[22:00] <DanielRichman> a non-action key
[22:00] <DanielRichman> just stops in place
[22:00] <DanielRichman> spamming space results in free time to think ;)

[22:47] <natrium42> yeah
[22:47] <rjharrison> Thought it might be good to get a plan together on storage and backup of data
[22:47] <natrium42> sounds good
[22:48] <rjharrison> I'm hoping to archive all flight datt from now on so it can be used for subsequent processing in the future
[22:48] <rjharrison> data
[22:49] <rjharrison> As well as provide an overview of previous launches
[22:49] <Laurenceb> SpeedEvil: it ablates more... not sure how big an issue that is
[22:49] <natrium42> i'm all for it
[22:50] <SpeedEvil> Laurenceb: ablation isn't a problem is big enough to drop Oprah Winfrey down.
[22:50] <SpeedEvil> Laurenceb: If the throat is
[22:50] <SpeedEvil> If it's 5mm across - it's _much_ more of an issue
[22:51] <Laurenceb> more like 20mm
