    So you've outgrown the Arduino? What do you want to do that you can't do with the arduino?

    Electric throttle

    What's the worst possible thing that could happen if the throttle misbehaved? What's the upside of making this change?

    Hall sensor

    Well, find compare the graphed output voltage at 30 deg too the temperature you expect to operate it at and see if it varies by more than 10%

    New diy'er

    When you say transmitter, you probably mean transistor. An fqa36p15 is a p channel MOSFET. They might see you back $5 plus freight. However there may be more than this that is faulty, and that assumes you're current that this one is faulty. It's possible, but not very likely that you'll find...

    Identify SMD inductor help

    The height is from the board to the top of what remains. The main part of the body seems circular, so estimate the diameter. Those should be close enough. If you can read the part number of U948. That's the part which looks like the switching mosfet (or maybe the controller). It could be...

    Identify SMD inductor help

    Ok... Well although the image is a bit unfocused, the winding appear thick, so if go for 10μH. Try to find parts of a similar size and see how 10μH would be marked (100?). A party of the same inductance in the same size package will likely be rated for a similar current. What is the size (h...

    Identify SMD inductor help

    There seem to be some parts of the broken package laying about. See of you can find the parts from the top so we can figure what was printed on it.

    3.3v circuit from a LiPo cel

    Why not pick a microcontroller which operates up to 5V or so? A diode is not a great option because at low currents the forward voltage drops.

    Biosense multipolar catheters

    I would expect this information is available from the manufacturer.

    Help with Amica WiFi board circuit

    Note the pin numbers. I suggest that when I Google that part number I'll find its a dual mosfet in an 8 pin package. Edit: yup. Just Google it.

    Technostar microwave problems

    Microwave ovens have interlocks to prevent RF being generated when the door is open. There should be at least two interlocks so that if one fails you're still safe. In at least one case, one of these interlocks removed power, the other placed a short across... Something. Is it possible you...

    Pioneer SA-505 clicking

    The previous advice was to manually operate the relay and see what happens. The relay is almost certainly part of a protection circuit. It is either failing to actuate because the circuit detects a fault, or because the protection circuit is faulty. In the latter case, actuating the relay...

    Help with a SMPS please

    Periodic clicking sounds from a switchmode power supply is never a good sign. I suspect that something is shorted, and a prime suspect is the output rectifiers.
