| Nov 25, 2011 at 8:34 | comment | added | Rory O'Hare | Oops, I forgot to mention that the solution has to be fully self-contained. No replacing batteries or charging. That's why I jumped at a piezoelectric solution, it produces it's own power. I know that with this many restrictions any solution might violate one or more of them. I'm really hoping there is a way to make the piezo idea work well because it wouldn't violate any of the restrictions (I think) and seems really elegant. Thanks for the idea though. | |
