    pc reset/led/hd cables..

    http://www.ebay.com.au/itm/PC-Computer-Case-Power-Switch-Cable-Connector-LED-/251004314767?pt=AU_Components&hash=item3a7105e48f i just want a few "1" pin only connectors (+) (-) or 2 pins (reset), those the type i mean and i'm not sure what you call them to go find them... thanks, ideally the...

    pc reset/led/hd cables..

    I'm looking for a place that sells just the little black (jumper size) connectors for motherboards, so i can run a cable from the LED power out or for that matter anything (with header pins) .. but can i find these? no .. is there a proper name for them? I have a relay with 5 header pins, so...

    More efficient SMPS IC?

    um, ok lol.. thanks for that but. let's presume 0.7v voltage drop per diode, what if, 180 diodes in series (or however many more it would take) to get the voltage low enough to around 3 - 5c for an IC chip to operate, the IC then is able to power up, to start switching, the 240v gets turned to...

    More efficient SMPS IC?

    for a long time I wondered how my PSU switches from 240vac down to Xvolts. So being ignorant as i can be, I just assumed, if you want 12vdc, there was some kind of IC that would deliver voltage only when the AC voltage (at50/60hz) between 1vac and 12vac meaning you only draw current for a...

    Basic theory of DC > DC (Boost)

    I bought a couple of 5 pins step up, and i don't need with the circuit, easy enough i just can't get my head around it. I can understand how step down works, eg, take 15volts, oscillate at a high frequency and reduce the voltage coming out and smooth it through a cap.... but going up? All...

    Relay "Ratings"

    Thanks :) (19 more seconds to wait before i can say thanks) ..... twiddles thumbs, looks out the window, it's dark um. time up yet? pfffft... Cheers :D

    Relay "Ratings"

    ahhh now i'm with it, i forgot about the arc/air gap/voltage ration... I was just assuming heat killed it, but of course so will the higher voltage.... so, let's say we controlled 20,000volts with a relay that only handles 120vac, i'm right in the fact the heat wont kill it or fuse, because the...

    Relay "Ratings"

    Never really fully understood this... a relay with specs of "7 amps @ 240volts" or... "120vac @ 12amps" be 1amp at 120volts (120 watts) or 240volts at 0.5amps (120 watts) that's the max the relay will allow, but higher the voltage the less current and less heat?... eg, imagine boiling a...

    LLPS

    Has yet to be invented? or has it.. what would it take to hook up 3 sensors of some kind that is able through the use of the other 2 sensors triangulate your position in a room?... has it been done? i was thinking 3 ultrasonic pules with a delay between each one measuring your distance or...

    Just worked out how to rid cancer forever...

    Very simple, downside is, if you have cancer, sorry, it's too late for our generation... our not yet born children yes they'll be safe if this idea / thought of mine takes on, i hope it does and as long as some credits me with this "idea" then i'd be happy, i have no other interest except to be...

    New TV Quiz Show...

    Basically if you've seen the show mythbusters and how do they do it.... Real Science ... eg, This is jimmy and i'm 43 years old, Does the Light in the fridge go out when you shut the door? i really want to know... is there anyway i can find out? thank you the [insert]||name of this new"...

    Do I need a step down adapter?

    I suggest you eat pizza less and when you do buy it from a professional :P - but seriously i'm too scared to go near mains voltages with a resistor lol

    Lightning Detector.

    The time is too short for the arduino and not 555?

    Lightning Detector.

    I came across this Circuit... I don't really understand the role of the 555, the 555 is set to monostable/1 shot, when current is inducted to the 4ft long copper wire, the voltage/current goes through this circuit, but why would you use the 555 trigger pin for a single pulse? why not...

    switch for my room

    Hmmm is there a reason for using the parrarel port rather than usb?

    Ice Age Internet Proof...

    If you re read my posts i was merely trying to understand it better or more to the point try to visualize what was going on... it was not until i came across the mathimatical equation to measure the speed of electrons and it was very slow so someone mentioned marbles as an example and i have to...

    Ice Age Internet Proof...

    I've looked at the data, you have not... you don't factor into solar spots, absorption rate of the seas, i've looked not at just the past 10 years but the past 100, i've seen patterns which should take 30 years but only happen in 10.. We should be heading into an ice age as of now, but because...

    Ice Age Internet Proof...

    Who's predicting an ice age?... That's happening for a fact... the sun has it's own cycle as well which happens every 400 years.. this is not about predicting anything at all... this is about giving internet to people who don't have internet after any large natural disaster, tsunami, ice age...
