We began talkin about a UMSF balloon - and who know what might happen if enough people think about something hard enough, thoroughly enough and long enough. How's about this as a starting point. http://vpizza.org/~jmeehan/balloon/ with http://www.chem.hawaii.edu/uham/part101.html as an important regulatory start point (I'm going to look up the UK regs for this as well) http://www.srcf.ucam.org/~cuspaceflight/nova1launch.html is also very impressive - all done in the UK This http://www.makezine.com/blog/archive/2007/...video_podc.html is particularly impressive - I like the multiple-cameras slant. Anyway - thought I'd get a thread going - this is an idea I like too much to let it gather dust in a corner - the one thing that I think would be nice to achieve is self-portraiture of some sort - think Beagle 2's WAM etc....perhaps in a corner of the FOV of one of/the imaging system. What sort of limit's should we set ourselves? 1kg 10x10x20cm? (sort of 2U Cubesat-on-a-diet budget) Doug |

Monitoring various sensors sounds exactly like a mission for a Basic Stamp or similar...light, affordable and programmable. I wouldn't rule it out of the equation even for a first test.

Well... considering the fact that Voyagers 1 and 2 were originally to be Mariners (though I have no idea if they would have been Mariners 11 and 12 or not), we *almost* got a second successful pair-launch out of the program! -the other Doug Well, really we did. The mission was approved and in many official documents was referred to as Mariner Jupiter-Saturn. It simply underwent a name change. -------------------- |

Someone suggested donating a Treo. There might be some Palm software that could run the exposures for the camera system or store information from a weather station. Would require a serial connection, IIRC.

Re Treo's and other potential offerings. They are great end user devices but trust me on this cos I do this for a living - you will encounter pain beyond belief if you try to develop any network oriented software worth attempting on any hand held platform that isn't based on Windows Mobile. I am a major, major fan of free (as in beer and as in speech) software and open source \ collaborative \ what not software but when it comes to hand held systems the only open platform worth working on today is Microsoft's. It seems mad to say it but their development environment is the most open and developer friendly system that you will find today. I know I can develop a GPS aware application (using either a built in GPS or one connected via Serial\IR\Bluetooth) that periodically (every 15-30 seconds) posts updated position data via a GPRS\UMTS\EVDO data connection, or via SMS, to a remote server of some sort using totally freely available tools for development and testing (via emulators for the platform and for the GPS). I've tried to do the same with Palm, Symbian (Nokia) and Linux (Motorola) and have been cut off at the knees every time.
Just my 2c. |

It is sad because I refuse to use a Windows Mobile device, to the point that I am still nursing my 4 year old Sony NX80v.

It is a Windows based Treo. Sorry I didn't make that clear. http://www.palm.com/us/products/smartphones/treo700w/ FWIW I used it for two or three months but hated some of its features and went with a Blackberry instead. I can probably sell it for $200-$250 on eBay, but I'm still willing to donate it if it will work. I'll even include the 2G SD card. -------------------- If Occam had heard my theory, things would be very different now.

Will it work in the UK do you think? Quad/Tri band is the requirement I think. I can buy a pay-as-you-go sim card over here and drop it in.

Got my three very very cheap cameras and the polystyrene enclosures ( perhaps a bit big - but even if I chop a chunk out of them and glue it back up it'll be a better job than a DIY effort ). Bloody postal strikes mean lots of other cool bits won't be arriving for a while.

Well - my idea of a front-door peep hole lens to get fish-eye for the GMC isn't going to work. On both the old catcam, and the new 3 MP cameras - they're FOV is too large to crop into the round FOV from the lens. So it's a WAM technique that'll have to work.
The normal cameras come apart fairly easily and I was able to hard-solder them to a housing and run them off 2 C cells instead of the two AA's that fit internally. I was also able to strip the flash and it's capacitor off the circuitboard with no ill effect - and I've been able to remove and re-attache the ribbon that drives the LCD with no problems as well. The shutter is actually on a tiny PCB of its own and that will be fine in terms of wiring something up. The trigger circuit that I thought would do the trick may not be up to it - it actually takes a 12v supply which seems excessive. Current plan for imaging.

. . . but when it comes to hand held systems the only open platform worth working on today is Microsoft's. Grin. I'm glad we built something you liked. I'm in MS Research now, but ten years ago I was on the original Windows CE team, from which Windows Mobile is descended, and I have the "Ship-It" award to prove it. If it would help, I could donate some MS software towards this effort. Or do you already have everything you need? --Greg |

I have nothing to offer this project except encouragement!
I must admit I lurk in this thread in to bask in the glow of the great DIY spirit. Oh, and for the occasional inside peeks at UMSF's "secret shedquarters" and Gizmo. -------------------- Lyford Rome

These crap 3 megapixel cameras will happily record a 15 fps 320 x 240 movie for 2 hrs none stop (just tried it - <200 meg video - 2 hrs 2 mins long). No sound...but I'm tempted to go with two cameras for photos, and one with a WAM for video. It works great.
