I would probably try to suspend everything inside an enclosure with rubber bands. Should be able to take quite a beating I would think.
Neat idea. I think it would be quite a feat of engineering to suspend electronics in an enclosure this way. I imagine the distance from the electronics to the enclosure walls would have to be relatively big. And the rubber bands would have to be tensioned just right and in all 3 dimensions.
fill it with floam!
At first I thought you just meant foam and made a typo. Then I looked up floam. I guess I skip too many commercials. I don't know anything about that stuff. Looks like it might be messy and get into the nooks and crannies of my circuit.
But foam (not floam) seems like a good idea.
