    need help!

    I ain't trying to be rude, but I can't see how someone with a degree can ask such a question on where do I get started. In all seriousness, a job in your desired field of expertise is as best as any place to get started. Maybe you should try to evolve your pov so it won't seem so silly. No I...

    magnetism.

    wow, I actually never thought of that. I know I would always ground myself out when I picked up sensitive IC's, but I was never really aware that putting them down may be just as bad. Makes perfect sense though...

    220 VAC to 24 VDC

    I think you could do this easily with a voltage regulator, there are plenty of circuits, even on this website. Do a search You may also find the datasheets on the LM317 very useful.

    incomplete circuit latching?

    Well first off that picture is blurry as hell to me, so i can barely read it. but, is the switch in the diagram the switch you are talking about or an external switch? Which wire is the switch connected to? Also, that module, I would assume that is just a basic block diagram, the actually...

    mobile phones as security cameras

    I have to laugh, lol. Anyway, if it was as easy as attaching two wires and viola, security camera system, then wouldn't everyone else already thought of it? First question that always crosses my mind when I think of something "Cool". why hasn't anyone else ever thought of it? Because...

    incomplete circuit latching?

    You ask "is there more to this circuit?" It suggest that you have no idea, so how would we know? I guess maybe if you would explain the problem more in detail and why you think the circuit is incomplete. Then we might be able to help you. FYI, assumption is the mother of all **** ups, assume...

    EMV Skimmer

    The mythbusters wanted to do a show about credit cards and their security. The credit card companies had so many lawyers that it became very clear, you mess with this stuff other then to use it in the way it was meant to be used and you can find yourself on the wrong side of a court room. You...

    Trying to build a 460-480v power supply for testing

    if your asking that question I am scared for you. even at ~900mA, there is enough there to take your life three times over and high voltage will make that scenario even more likely. Be careful You have 460V service at your work? Don't you mean you need a 120/240V primary and step up to 460V...

    Transistors in logic gates. Basic question.

    I don't think so, AND gate compares two inputs, when both are the same the output is the same as the input. Turning a transistor on or off doesn't make a gate, Think it is a little more complicated then that.

    How do i make a 60sec security system timer?

    If you are willing to spend the $20 dollars and time is an issue then I would just buy a time delay relay. If you are really interested in what I am talking about, http://gurutechy.files.wordpress.com/2011/09/alarm_circuit.png the only difference would be how your trip circuit works. The...

    Computer front panel audio

    I have noticed the same thing with my mouse and audio. I have commercial gear to, so you are fighting an issue that isn't easily fixable. Or at least one that hasn't found a solution over the years in the computer industry. I always noticed it was way worse with a bigger amplified signal, so...
