Raspberry Pi - 90,000 above the Earth

Very cool post.

Given the RPi sensitivity to light, I was curious if it would work at that latitude given the increase in radiation levels.

If you are concerned about lightning, wrap the inside or outside with aluminum foil or copper screen so you make your own faraday cage.

This is so cool. Excellent work to all of you. I hope the other 6 go well for you.

Nice work.

There is some interest here, and I know someone who has some Raspberry Pi's that he might be able to donate for the cause.

Your sensor may require to be calibrated aginst the barometric pressure.

You could apply the correction afterwards on the raw data, but you need to know the pressure before takeoff.

Can you supply a few more details such as the Battery sizes, the run time you got, so that others have a starting point.

How did you know where to look for the recovered payload, and how did the box fair.?

Personally I'd be adding a few more ties or velcro restraints including the usb and ribbon cables.

You're also keen using a breadboard under such rugged conditions.

I imagine you'd need the Pi to supply heat to any housing that covered the lens, since at that altitude it is very cold outside, and the housing could condensate/freeze over.

Outstanding!

Congratulations to you and your team.

perhaps, you could enclose the cameras and place a tube coaling around the apertures to protect them and limit optical distortion.
