    Driving the vibe

    Thank you (*steve*) ! I couldn't understand most of what you wrote, but it gives me a place to start studying. I don't know if it will change anything, or make things easier, but a few things came to mind. The LED display is much less important. It would tend to distract if relied upon too much...

    Driving the vibe

    Can somebody help me with a project? For hearing impairment: I need to change a "beep" into a "vibration", and a analog meter needle into a rapidly flashing LED. This would allow my wife to enjoy the hobby of metal detecting, despite her hearing loss. I know very little about electronics, so...

    current limiting diode

    Please dont laugh too much, the following is a note I sent off regarding a cld (diode) I attempted to use...I need help. In pipe fitting, almost everything is in line and parallel connections rarely effect the function of the main. I think this is where I am missing it. My beloved current...

    CLD's

    Thank you again Resqueline. I'm dying here. I've been trying to absorb as much knowledge as possible to utilize the solutions and suggestions on this and other forums. My brain is fried. Will you please help me with which FET I need for anything around 4 to 6mA using a 30 vdc supply? How to wire...

    on line components

    Can anyone recommend an on line source for electronic components that doest have large minimum order requirements, and ships next day or kinda fast? I don't want to buy 500 resistors when all I need is a few. Thank you, plumber

    CLD's

    It seems descriptions vary on components enough to cause worry when ordering on line, then I walk into a radio shack, and get really confused. I need to properly describe and order a "Current limiting Diode" that will keep mA's around 6 mA. On a 30 volt dc power supply. And yes it is just a wall...

    manual current control

    linear? I cant find enough stuff on linear pots to grasp the difference. Is it simply the slide type? And why would I need a linear pot as opposed to a non - linear pot? I'm just trying to learn. Thanks, plumber

    manual current control

    voltage drop Thank you very much!!! I had to do a lot of reading and web surfing to realize your reply was awesome and to the point. I even dabbled with some long forgotten algebra. But I think I got a handle on it. Sooo, as far as voltage drop...do those resistance values indicate the lowest...

    manual current control

    Is there a novel/simple way to manually adjust amperage without affecting voltage? At this point, I am trying to determine an effect, with out selling the farm or frying my fragile plumber brain. I really don't want to buy a regulated, variable power supply for my simple experiment. Building my...
