If there's a source of fresh iron filings around, you also could make a cheap oxygen scavenger by putting some unrusted iron bits into a separate ziplock bag. Many of the oxygen-absorbing bags that you can buy are essentially the same thing. Pack the absorber bag next to the injector bags before applying the foil wrap. The majority of the leftover O2 that's slowly swimming around inside should hit an iron filing before it hits an injector interior. I'm guessing that this second step would not be worth the time to do it, but one bonus is that when you open up the bag later, you can quickly check the filings. If they've rusted even a little during storage, then maybe that extra step was a good idea after all.
The initial problem is the use of ethanol based fuels that draw in the moisture causing the corrosion. With these fuels cleaned out and the water dispersant in place, I believe it would take more moisture than what seeps through a zip-lock to warrant the other steps.
It is some good information for those that live in really humid climates or extended storage. Thanks for the information.
I found this video because I still remember the music in the credits. Does anyone know if that music is part of a complete song? Google's music search function couldn't find a match.
The military has long funded research to put cameras into mortar and artillery shells, to be used as short-flight recon drones. A couple of examples are at Georgia Tech (search for reconnaissance round gatech edu) and West Virginia (search for wvu edu smart projectile).
Unfortunately those examples are from cameras that aren't much faster than a normal video frame rate. I was hoping for something more like a million-fps bullet-time video from the viewpoint of the bullets. Given the cost of Phantom-grade cameras, however, that's probably not practical yet unless some rich person wants to fund the research. By the way, if some rich person is reading this and thinking "cool beans I should like totally fund that because science and stuff", please bring me into the project!
Still, it would be cool to see a Go-Pro launched in manner similar to mortar shells, and that project looks to be a lot more achievable. I suggest starting out with launching it on a rocket at first, to see if the images can indeed be restored in post. If you decide to get gunpowder involved, it might be a good idea to put in a lot of padding to smooth out the initial acceleration.
