    24VAC half bridge rectified = xx DC???

    You clearly don't know the difference between full and half wave rectification (besides the very basics). Either will give you about 33VDC from 24VAC. Can you get a relay with a 24VAC coil? You might get away with a resistor or a 20V zener diode in series with the 12V relay coil, but...

    Home stereo compatible with 12v campervan?

    Yep, I sure can.

    And of course, voltage is not power. Several similar devices could consume the same amount of power but require different voltages.

    An easy mistake. I hope it all goes smoothly for you now. Are you making a modular synth?

    24VAC half bridge rectified = xx DC???

    It's not the transformer that's the problem. Google a bit for differences better full and half wave rectification. To get 10 to 14 volts you'll need (at its simplest) a filter cap and a regulator. What is the nature of your load?

    24VAC half bridge rectified = xx DC???

    You will actually get a slightly higher voltage from a half wave rectifier, but the ripple will be at the same frequency as the AC (it will be double for a bridge rectifier) and it will be capable of supplying less power.

    12V to 33V Converter

    I'm not sure what purpose that transistor serves.

    Best way to detect what power source is connected?

    It's not abusing the gate, it's abusing the signal to the gate. The gate drive signal is there to switch the MOSFET, not to power a load. However, assuming a fairly low impedance drive to the gate, it may work. Edit: "hardware back:? Possibly.

    12V to 33V Converter

    Have you looked up the datasheet for the TL594?

    I have a question about a fan I built using a dc motor.

    If you've got it running from a USB port then it is likely it takes an initial high current which turns the motor rapidly but which also triggers the polyswitch protection which then limits the current to a lower value

    Transistor pair to switch between Voltages

    Yeah, although typically you'd draw the p channel one up the other way.

    Colin, I'm giving you a week off to contemplate how to post something positive.

    Please don't tell us that you powered on a mains appliance whilst disassembled and holding a potentially live part of the circuit. Aaaaagh!

    Transistor pair to switch between Voltages

    I find that drawing in the body diode on MOSFETs helps a great deal in getting them around the right way. Then, knowing that in simple switching applications the source is connected to the same supply rail as the channel type, you'll get everything the right way around.

    What is your current level of knowledge and experience with electronics? Perhaps you can go the amateur radio route? Are the any amateur radio groups near you?
