QUOTE(skywardsword @ Nov 29 2012, 12:08 PM) Hey C-Fu and other electronic gurus, No,the watt is the power rating of the resistor.its the amount Of power the resistor can take.exceeding the power rating will cause the resistor to blow. 3 watt is a lot I thinkI have some question. For resistor with rating 100ohm 3 watt.(same thing for 330ohm 1watt.) What does the 1 watt mean? The resistor it self draws 1 watt? If connected to a 12V sla battery. How many V drop does it cause? Thanks so much, Skyward |

QUOTE(skywardsword @ Nov 29 2012, 07:59 PM) the sealed lead acid is for cree xpe leds Haha,I'm still planing on a 2A USB hub driven by 9v adapter..parts are shipping in with the Pi..why use schottky diode? Try using a 7805 voltage regulator,5vI have some other problem powering the pi directly via usb hub. So I have a dell x50v, dc adapter rated for 5.4v. zero load it measures 5.6v. So I tried to put a shoctty diode to hopefully give a forward voltage of 5.3v. However, it does not seems to work with my usb hub. I soldered in series to the usb hub input. Across the diode, indeed the voltage measured 5.3v, but if I include the usb hub into the measurement it shoots up to 5.5v... I wonder if the polyfuse on the usb hub got blown... since I measured the usb ports voltage and they come up to 100mv+/-  /newbie - I just blown my first diode. spectacular poofff |

QUOTE(skywardsword @ Nov 29 2012, 08:59 PM) 7805 need more then 6 dcV to provide stable 5Vdc 2amp, or so I was told and read. Use LDO voltage regulator then,their range of input voltage are more flexible,even below 5v can drive itIn your case if you have a 9v adapter, down converting it using the 7805 should be ok. |

QUOTE(skywardsword @ Nov 29 2012, 10:33 PM) Hmm, can you suggest a specific part from my.element14.com so I can place the order without making mistake.(I accidentally bought smd, and also some huge resistors...) After sorting out,I think u can try this,Thanks  http://my.element14.com/micrel-semiconduct...d-5v/dp/1556712 Output current 1.25A Minimum input voltage 4.3v Max input voltage 26v But it cost 8 bucks |

QUOTE(linkinstreet @ Nov 30 2012, 07:18 AM) So now since we can't purchase from element14, do we need to purchase directly from reseller? Can't find it listed in Thundermatch's website even tho they are listed by element14 U can still purchase from element14,just click "buniness" instead of "personal",it will direct u to element14 order page like old times |

LoL!one month my pi oxidize into powder lo -.- haiz...searched thru the forum all sell so expensive,even the cheapest can buy another new pi |
