1 day left; Todays work:

So, today i finished the flightcomputer and tested it succesfully!

LAUNCH: ~11:00 (GMT+1) on Sunday, 1 Augustus 2010,

Lets start with a picture. I like pictures.
So here i was in the train, checking both the flightcomputers, mostly the 2 GPS’es. The Falcom module kinda worked, which was great news. It found some small bugs, which is good too!

You can see i am still using some breadboards..

So then, bugs fixed, time to get serious. I got a PCB and soldered everything very neatly together as you can see >>>

So that’s the entire flightcomputer! (phone is not in picture).  But i just went out to check its workings, and the 2nd GPS (Falcom) wasnt getting a lock, which sucks.

So then i decided to run all kinds of predictions from a new launchsite. On this launchsite i can prepare indoors, and let it out at a safe time, and so we can measure all characteristics to get a good estimation right before launch. If the wind changes though, we are going to have to switch back again to the old location.
Oh yeah, in case you wondered, i bought a nice red rubber boat.

Before launch we will also be checking that there are no planes comming on our route via the tracking website http://www.flightradar24.com/ where you can see all the airplanes.

Work for tomorrow: building the externals and hooking up some of the sensors for testing!

    Hoe heb je die verwachtingen gemaakt met de hand of heb je daar een programma/website voor? Daarnaast hoe kom je aan de windsnelheden en -richtingen in de hogere luchtlagen, KNMI?

      Het KNMI is ongelofelijk onbehulpzaam geweest; elke moeite werd gespaard. Dus nee. Nee, ‘de Amerikanen’ verspreiden tabellen met GFS data, dat is data in 21 luchtlagen of 42 (HD) luchtlagen. Dan weet je precies wat er gebeurt. Als je vervolgens je liftsnelheid weet (en dat weet je) en waar hij klapt (ik schatte 32km en dat werd het ook), en je weet hoe snel hij daalt (dat weet je ook!) dan weet je precies waar hij terecht komt. Ware het niet dat hij té veel lift had, daardoor harder ging, en eerder landde; niet in Friesland maar in het ijsselmeer.
