    L7805CV 5V Voltage Regulator to IP camera over POE

    You said that it worked fine when using the 10ft cable. You also said that the LED indicators on the camera seem to be indicating OK. I think this leaves miss-wired data lines or possibly a discontinuity in a crimp. Do you have a CAT5 tester? I'm not talking about an expensive model that sends...

    For what value of L, will this circuit resonate at 332kHz?

    I still don't see the point of this. If the original (switched bandpass) circuit still exists what's the point? :confused: You don't reinvent it. Just fix the damn thing! Chris

    analoge to PWM with a fixed 10 MHZ frequency

    I'm getting slower by the day and I confess that I didn't get this initially. Yes she is! ;) Chris

    It's 6 in the drop down list under "Tools". Chris

    Circuit for converting ammeter to voltmeter.

    That's my point. Multipliers can't be used with the movement shunted. Since the shunt is internal you'll probably damage the movement when trying to remove it. Chris

    Magnet coil help (turns, gauge, for coilgun)

    Dash meters are expanded scale but not known for lab accuracy I'll check mine when I start my truck tomorrow. Chris

    Circuit for converting ammeter to voltmeter.

    Analog voltmeters usually employ a 50uA meter movement with series multipliers. You're 2A meter is not suitable for use with multipliers. A center 0 ammeter is nice to have. I wouldn't screw it up if I were you. Chris

    Magnet coil help (turns, gauge, for coilgun)

    Have you ever watched your car's voltmeter when you crank the engine? Chris

    analoge to PWM with a fixed 10 MHZ frequency

    Well, I like hot blonds but what does this mean? Chris

    Battery powered wireless microphone

    I really wasn't sure what an 18V lithium would charge up to. I assumed it was > 18V. That said CC's safety solution is cheap insurance. Chris

    Help with reading schematic

    Has anyone taken note that this thread has no continuity? It's all over the map!! :eek: Chris

    Magnet coil help (turns, gauge, for coilgun)

    As per the charts @ http://www.cirris.com/testing/resistance/wire.html 14AWG copper wire is 0.002525 Ohms per foot. Do the math. 3 Ohms doesn't compute. Chris

    Magnet coil help (turns, gauge, for coilgun)

    That equates to a mere 13A load. Chris Edit: I missed that you said you have 100 turns. What gage wire is this?!! Chris

    For what value of L, will this circuit resonate at 332kHz?

    Duke, I think you were correct the first time. Redesigning his filter makes little sense. Chris

    diode for collapsing magnetic field

    This is getting more perplexing by the minute. Usually over heating a diode will short the junction. In your circuit a shorted diode (#13) should only cause one of your LEDs to indicate when it shouldn't. Since manual still works I guess it's possible that a resistive junction may have been...

    L7805CV 5V Voltage Regulator to IP camera over POE

    Agreed but did you read all of what I said and asked? Part of my replies are in quote boxes embedded within your quotes. It questions the data lines. Chris

    analoge to PWM with a fixed 10 MHZ frequency

    Ha, you read my mind. Chris

    L7805CV 5V Voltage Regulator to IP camera over POE

    Unless it's loaded the measurement will be meaningless as it pertains to voltage drop. Chris

    Battery powered wireless microphone

    If 18V is the absolute max limit for this device you may want to consider running it off a 14.4V battery. If you use an 18V model you will probably exceed 18V when fully charged. Chris
