    4 rechargeable AA batteries to standard USB power line

    also have a couple of 115-220V AC plug to USB power adapters to spare. maybe i could rip a few components from those? honestly, i know very, very little about electricity/electronics, and i can't deny it.

    4 rechargeable AA batteries to standard USB power line

    basically, i bought this $5 worth of battery holder that is supposed to connect to USB to power some of my devices (basically, a backup source). i already have 4, 3800 mAh AA Ni-MH batteries (or so the label says), so i was like cool. but the thing is the battery holder doesn't really work. so...

    NC switch with time delay

    alright... this is what i'm trying to say... under normal conditions, the circuit is closed for the path to Va, but sometimes, (now this is the unavoidable behavior of the components), a voltage will "SPIKE" towards Vb (well that's not actually what's happening but for a simplified model, we'll...

    NC switch with time delay

    alright, would it actually help that there WON'T INITIALLY BE current or voltage difference between the source and drain, as it will be open all that time and the depletion of the gate is simply a way to keep it such open, when there would be a short period in milliseconds that the path from...

    NC switch with time delay

    uhhhh?? no workies?? wahhhh wHAAAA!!! tantantannnnNNNNNN....

    NC switch with time delay

    ok.... how about..... THIS: [take a'look at attached image!!] tada! more details: oad voltage: ~6V load current: ~500mA ... but it opens it, so i guess breakdown doesn't matter that much gate/trigger: ~6V gate/trigger: ~500mA nyah

    NC switch with time delay

    waitta... i thought, thought i did, enhancement mode mosfet are normally open and depletion mode are normally closed  ???

    NC switch with time delay

    i'm looking for a component that is normally closed, but when voltage/current is applied to the gate/trigger, it will: 1) open the load (turn it off) 2) keep it open while the current/voltage is applied to the gate at *around the same amount* of trigger current/voltage 3) keep it open for a few...

    toner transfer from Orcad PCB Design

    i'm using the pcb designer from orcad 16 suite and by the looks of it, there is no "layer by layer" printing. so can't really "turn-off" the silkscreen and extras all at once.... nope. there is the option changing the visibility option of tolerances, silkcreen, values and those thingamajigs...

    toner transfer from Orcad PCB Design

    new to de forum guys! neways, so i started teaching myself EDA and specifically designing pcbs. the software i'm using is Orcad PCB Design. so when i'm finished with a project and want to etch it, i'll be transferring it to the pcb using the toner transfer method. but i'm not really sure as to...

    lookin' 4 switch with reset

    hi y'all! new to the forum. so i'm looking for a push button that when i press it, it goes on then again goes of. but then has an extra pin that when current is applied, it turns off whatever the previous state was.
