1. Fire StartingThe practice of shorting out the cell phone battery to heat and melt a piece of wire MAY work if the wire is small enough and the battery in the phone had a sufficient charge and the two points on the battery were known as + and -. If the wire size is too large you’ll merely heat up the battery and kill it. I’d start with a small filament wire. Finding “wire” in a cell phone however is not the correct terminology as there are no conventional “wires” in a cell phone. You are talking about extracting a surface mount run from the circuit board. Good luck with that.4. CompassI really doubt that a speaker magnet from a cell phone speaker would have enough magnetism to magnetize a wire to move a leaf in a puddle. The magnet in a cell phone does not have enough magnetism.5. Catching Food (Process 1)Rather than relying on a flimsy circuit board tied to a stick a would just sharpen the stick.
Heh, interesting. I'm not sure how effective all of these would be, but A+ for thinking outside of the box. At the end of the day that's more valuable, anyway ;)
All comments on this blog are moderated, meaning they don't appear until approved by me. So, when your comment doesn't appear immediately, *DO NOT* throw a hissy-fit and assume I'm refusing negative comments (yes, it really happened). I approve pretty much everything that isn't obvious SPAM, negative or not, and I promise you that will include your hissy-fit comments, accusing me of a grand conspiracy to squash dissenting ideas (also really happened). The result, of course, being that you will look like a fool, and the rest of us will laugh heartily at your stupidity.
