| 458350 | 2006-05-28 09:38:00 | Paul - Why not, I am an electronics student and I want to learn and build circuits so... :) Burnzee - That sounds very simpler than my idea, I tend to do things the hard/long way :rolleyes: Whay type of battery would you suggest? Oh and you have PM ;) |

| 458351 | 2006-05-28 10:42:00 | mayby it s the beers talking but how about something really simple....a diode (to stop it feading back to other devices and a bunch of big caps :) | tweak'e (69) | ||
| 458352 | 2006-05-28 11:01:00 | Diodes, yes, exactly what I have in mind but the big capacitors? Have not done the sums but how many would we need to run up to and exceeding seven fan motors and what value? Very little room in his computer case. Besides this has the drawback of inconsistant cooling as the capacitors start to discharge. Don't worry we will make the circuit available to everybody and it will be simple. BURNZEE |

| 458353 | 2006-05-28 11:16:00 | tweak'e - The thing I don't like about the caps is they drain off and there will need to be a lot of large ones by a guess :D, looking to power 9 fans thats the lot :), 4 in the front, 1 side, 2 rear, 1 PSU, and CPU. Maybe GFX card if not too hard ;) (that will make 10) They are LED fans, but I am doing some modding at the moment to make the LEDs run independantly of the fans (separate power source). Burnzee and I are designing a circuit as he said, and we will make it available to everyone :) |

| 458354 | 2006-05-28 11:53:00 | yeah with so many fans the case might be completely filled with caps :D the big problem with useing a battery is charging a 12v battery with a 12v supply, to properly charge a battery you need 13-14v(depending on type). i think the solar power charges can fix that. one thing to watch with your ciruit......noise. a big dose of electical noise next to a cpu etc might make thing....mmmmmm............interesting ;) please post back on how you get on. |

He he he yeah... :D Yes, looks lik we are going to get rid of the battery idea. What do you mean, noise? what will it do? Don't worry we will keep you informed :) |

| 458356 | 2006-05-28 12:05:00 | no caps no battery???? what are you going to do, run a 2nd powersupply? noise.....electical noise...EMF. for eg my battery charger screws up the radio and tv reception, that sort of noise can do cause data coruption when it strong enough and close to a cpu etc. |

| 458357 | 2006-05-28 12:11:00 | I know, I am leaving it up to Burnzee, He seems to know what he is doing :thumbs: and going by the one posted earier in the thread, that has no batterys or caps Oh I see... |

| 458358 | 2006-05-28 12:31:00 | EMF or electrical noise won't be a problem as the unit will be completely solid state, ie no relays etc . BURNZEE |
