| 342041 | 2005-04-07 05:32:00 | I'm making an organic mouse. There are only a few problems so far: it screamed when I soldered the tail to the connector, the tail's a bit short, and it craps everywhere. But the EM radiation is virtually nil. |

| 342042 | 2005-04-07 05:36:00 | the tail's a bit shortYou could hang it buy the tail for a week to strech it out to the required length, add weights as needed. | Rob99 (151) | ||
| 342043 | 2005-04-07 11:44:00 | hehe...love flushing out the ACT voters :) Tony, Are you suggesting that I am not being serious by questioning if my childs health could be effected by having her hand for periods on top of an infra red generator? I thought that was a concern of reasonable parenting... can you quantify 1% of sweet fa at all ? good to have the figures... agree with the OOS and obesity comment... :thumbs: Pete |

| 342044 | 2005-04-07 12:33:00 | In a work environment, no advantages. For gaming, the opti is better. I certainly find them an advantage when working with graphics. IIRC, can't the RF from cordelss rodents disrupt laptop touch screens, pads or something? Anyway, I'd imagine you'd come to more harm going out on a cloudy winters day without your sombrero on hmmm... put a sombrero on the rat and call it Speedy :D |

I truly believe that today's children are in danger of turning into nervous adults who are frightened of everything because of the current national obsession with wrapping them in cotton wool and trying to avoid every possible risk, however tiny. Life is full of risk, and the skill is learning how to recognise and deal with it, not just trying to avoid it all costs. |

| 342047 | 2005-04-08 00:01:00 | Pete: Do you have electric lights? Standard incandescents emit less than 10% of the power as visible light . Most of the rest is IR . If you have halogen lamps, they emit quite a lot of UV as well . (Though those built with dichroic reflectors let half of the IR out the back, and the ones with a clear faceplate absorb some of the UV) . A traditional mouse has IR LEDs, which are housed in the opto-interrupters used to track the ball movement . None of that IR escapes . (They have had trouble with the IR in bright sunlight stopping them working by overloading the sensors) . An "optical" mouse doesn't use IR . You can see a red light from it . That's at about 600-700 nm (nanometres: 1 nm = 10 Angstrom) . IR is at about 900-1000 nm . You can't see that . |

Thanks for the mouse LED info I didn't know that . . . Pete |
