Wow. How far until the satellite is finished?


Satellite is mainly completed except for the High Gain Antenna. See details here:

Sure!

Doesnt look great for the team

"It’s now T plus 100 hours, and we still have not heard a blip from our test balloon since launch on Friday. Joshua estimates that the battery of the recovery system can last about 5 days (120 hours), making it pretty unlikely that we are going to hear anything at all from it at this point. "


I seem to remember Prometheus losing their one too! I think someone found it and rang them, so good luck guys!

Hey James
That's an interesting chip!

Monroe


Sorry didn't see comment earlier. I'm part of the Broadcom team working on the BRCM2727 - it's a pretty amazing chip! Camera ISP (up to 8MP), HD (720p) record/playback, OpenGL and OpenVG acceleration, audio. All at a very low power consumption (I think 720p encode is < 500mA). Designed for mobile phones and the like, but I reckon there are so many products you could make with these sorts of chips that we shall start to see some quite innovative stuff coming out once people realise what is possible.

Given the media interest in rocket flights, you could afford to have 10 boards, each with an HD record capability, spread around the craft, each board needing the 2727, camera and SD card plus battery. Each board would be < $50!! You could easily switch recording from stills (8MP) to video and back, so video, then hi-res, then video etc. Sound recording etc. You could probably even interface it such that the SD card also logged flight information (plug in GPS to it etc). Each board would be smaller than a matchbox.....

Loads of possibilities!

Hi all,
We have scheduled a new stratospheric balloon flight in order to repeat the test for the recovery system WBRS.
It will be in december 19, 2009 in Zaragoza (Spain). See the progress at:
http://www.wikisat.org/?page_id=9
This time, Payload will be a Lunar Rover prototype from GLXP Team FREDNET.

My best,
Joshua

We lost the WikiSat Balloon Recovery System in the Launch #1 but this time we try to attempt a second chance with a validated code of the WBRS written by Anders Feders. I validated the program and it works very well in my car so I hope it will work in the balloon as well.

This time we take pictures. This is what the WBRS is watching now:

Well,
A bit late but we want to inform you that we succeed to launch and recovery the third high altitude balloon in collaboration with DAEDALUS group from Spain.

http://wiki.teamfrednet.org/index.php/B ... aunch_.233

We tested the satellite that was only 14 grams and other componets that we will use in the Wiki-Luncher.

Also you can see a WikiSat report here:

I'm excited! So far I'm putting my money in your direction... I don't really know for sure... But good luck!

Hey guys!
Finally we have the version 3 of the WikiSat, a femto-satellite less than 20 grams:

Finally we have tested our launching ramp for the WikiLauncher in near space and we recovered!

Joshua,

What is the purpose of the launcher? Is this for ejecting a small satellite in orbit to meet the N-Prize requirements for a mass of 9.99 to 19.99 grams?

By the way, do you have another link for the video from the third high altitude balloon in collaboration with DAEDALUS? The link in your earlier post seems to require being a member of FredNet. Wasn't that the mission where you used two balloons, and recovered the payload with one of the balloons still inflated? That was amazing.

Dave
