So /g/, I've been thinking of creating my own satellite
I'd do a test run with like a weather balloon but if I could do it it'd be grand.
>use raspberry pi connected to cameras, altimeter, thermometer
>record data and video of launch
>send it into orbit then which now costs about 8k
This is a great idea /g/
what are you going to do about radiation flipping the bits in your sat, What are you going to do about temperature controls. What are you going to do about communication.... Who do you think you are going to fly with?
so much this. I was helping to build a computer to send into the upper atmosphere, it was a nightmare. The first computer was put in a vacuum chamber to test it, it got over 60 degrees Celsius. The second got down to 30 degrees, and the third got to a 25, which was the one we sent up. It worked pretty good, though managing heat sinks and weight is killer.
I don't recall having to deal with this, but I probably did.
this was no issue for us, we'd be getting our hdd and backup drive back. But we put in an antenna and software defined radio and sent bits back and forth, this was mostly just for reading temps and shit, not all the data it was supposed to gather.
All in all, I wouldn't recommend anyone that isn't a team of physicists and computer scientists or someone with a lot of money to blow to do this, there is more testing and problems than you'd think...
for OP's purposes, you'd be right. For a research team, you might want the extra power for cameras and all the sensors with any calculations you might do. Also, a full pc like this would have usability or resale value after you're done with it.
If I were smart, I'd probably learn how to launch satellites. Just so I could launch them at other satellites.
Is it a crime to crash into other people's satellites? What's the jurisdiction on that?
I worked for the software on these OP.
They're basically still in the "toy technology" stage.
IIRC it's around 50k for a launch (commercial, might be less for student/private).
You'll need a really powerful groundstation to be able to do anything remotely useful, and even then the company I worked for was barely able to get more than 25-50 KB/day of data, if they could even contact it at all.
