Anti-Resonating-Technology.
Hello,
Idea for anti-resonating-technology, for harddisks and cooling fans possible other things. First I shall explain what I think causes resonance problems: Think of soldiers stepping on a bridge. Each time a soldier steps down, it makes a downward movement on the bridge. Each time a soldier steps up, it makes a upward movement on the bridge. In other words, anything that makes a circular movement, or even slightly circular or even just up and down, behaves like a cosinus or sinus wave. Anybody having had math on high school knows what a cosinus or sinus wave is. And the problem with waves ofcourse is... if they have the same graph... and the overlap at the peaks and the valleys they complement and increase each other. So the wave becomes the addition of the two. So this is what happens during resonance... the waves overlap perfectly... and start becoming one big wave. To prevent this requires keeping the waves out of sync... and preventing overlap. One possible simply idea to keep stuff out of sync is introduce a little spring, possibly chip controlled. The little spring uses a random number generator or so... to cause random up and down movements... to try and break the wave pattern. Hopefully all devices start "waving in random fashion" so no overlap occurs If this would work in practice I dont know... but it's worth a try ! =D Also I suspect if the waves do not counter each other perfectly in the first situation... then the waves will start to influence each other... like a dynamic algorithmm which modifies each other data... anyway... what happens is... each other's waves starts to fluactuate... walk differently... like pi slightly being modified/radians.... And sooner or later they start to overlap... it's like the waves start walking a little bit... until they perfectly overlap... from that moment they dont influence each other anymore and they stay perfectly insync... So that's why resonance becomes a problem... so keeping them out of sync is the game ! =D If random pushes up and down would keep them out of sync and counter act walking I dont know... but it's worth a computer simulation try... just a simple one Hopefully the push up and down is powerfull enough to break the sync ! So maybe if it's not powerfull enough, it might not shake them apart again would be funny if that happens if a computer simulation (not breaking apart ) Bye, Skybuck =D |

I didn't mention this in the original posting assuming people interested in
this might know it already, but I still mention it for those that don't know this yet (to lazy too modify it, it would have been possible since newsserver was down for a while at least for sending which was kinda weird, anyway): This anti-resonating-technology would not be ment to reduce sound vibrations so much... though that would be nice... But this technology would actually be ment to prevent harddisk sector damage from occuring. Apperently multiple harddisks can start to resonate together, and this could cause heads to go up and down... and cause sector damage. Perhaps this is why Windows 7 shuts down harddisks to prevent this kind of damage... it could also be just a power saving feature... None the less it's probably a nice feature in windows 7 ? unless the powering down of hd's could somehow lead to damage by itself ? Maybe bad parking of heads ? Bye, Skybuck. |

Rubber sux... it will "dry" and become "brittle". Lol... I saw such tiny rings or even tinier... brake off from my Pentium III PC which had this ****ty case... using rubber pins to hold up the motherboard... perhaps the breaking of those pins by gravity or so... cause a short circuit and blew the power supply... who knows or maybe the power supply just gave up... an old cheap china power supply not selected by me ! The pentium III 450 mhz is now powered by the Seasonic S12 600 watt power supply ! LOL =D Many power cables inside the pc on the drive bay though... that is kinda worrieing... I hope now power discharge to the case will happen So far it seems to be working fine... Good thing to go back to my DreamPC soon... at least it should have everything properly connected and not have any loose cables... it also has a decent power supply with detachable cables... can't remember the brand exactly... AZX power or something... or ACZ or something oh well... no brand label on it and it's dark again ! Lol =D Bye, Skybuck =D |

As a matter a fact I do have a bad back... because of gravity... so fixing
my DreamPC is extra painfull for me... I most be carefull... I could seriously hurt myself ! So far fortunately I take it easy... and only modest ammount of pain... very slightly... as soon as I feel any pain in my leg I stop So far that only happened once... Another good reason why not to buy too heavy PCs... for now I am ok... but I don't know about the future... my back is probably slowly healing... but if it does get worse... I will have to get tablets/laptops instead of heavy pcs Also the plastic pins were so tiny and thing... they easily wear out and brake... so rubber or plastic doesn't really matter, the effect would have been the same. And there is no reason why gravity could not brake it off... the motherboard is kinda heavy... But I will admit that there was a weird situation going on with the PC lol... There was only 1 screw holding it up... and the screw wasn't even proper... But perhaps that happened after it already blew up... I was just too lazy to attach screws properly since it already died... So perhaps that caused the plastic pins to take more of the load... It eventually broke off when I started to pull parts out to rebuild in the much better chieftec case so there ya go ! Another nice example of how strange events in life can take out plastic crap ! Bye, Skybuck. |

Also just to be clear, these were the pins on the pentium III 450 mhz
case... which is now more than 12 years old at least. In the past I had to take motherboard out/in/out/in/out/in/out/in... to try and fix sblive crackling or not working at all... (sb16 is in it now, still crackles/chipset issue ) So the plastic pins already had plenty of wear and tear... something that doesn't happen too much with metal... For me: metal all the way ! Bye, Skybuck. |

No where did I mention noise ?
So what you on about ? Randomness can be considered noise, perhaps that's what you on about ? Surely a little spring moving up and down won't create any noise... it will just offset the movement so it doesn't get synchronized, which is the whole idea ! Just like soldiers not walking in sync on purpose Bye, Skybuck. |

You would be better served going back to the 1700s. Did you just come hear to troll ? Or did I upset you because I invented something awesome just yet ? =D Bye, Skybuck :PPP =D ^ Extra long tong for you ! LOL =D |

Slightly extending your description, NOISE is an "Anti-Resonating-Technology". And contrary to your "explanation" of waveforms becoming synchronized, NOISE remains NOISE. And it gets in the way..try talking to someone else in the noisiest part of a steam plant, or ten feet away from a running jet engine; noise is soooo helpful.. |
