    Schematics Variable current 12v 60A to 0A

    Dazza, It can be done but not with good efficiency, it should be possible to charge with constant current. There will be heat losses because the voltage is sometimes twice the needed for charging a 12V battery. And it will work only as long as the voltage from the alternator is higher than a...

    Make a Microwave oven on a small-scale

    Dazza, Interesting story! Well it all makes sense to me, so it must be correct! ;D But I was wondering about the waves influence on the electrolysis in the reactor. Will just a little rubbing of the molecules improve the amount of hydrogen produced or the speed of the process or both...

    Ashweth, What do you mean suggestions, where to start or choice of material or what? Kumaran, I like the idea of using a harddrive, good bearings, good balance and easy to get. The core for the coils is a bolt, this is steel and not optimal for a magnetic core. Try to get

    Measuring voltage output of Serial/LPT port

    Hi Rhonn, The voltage put out by the ports can be viewed on an oscilloscope or measured with a multi-meter.

    voltmeter with more accuracy

    Hi Sharath, The technique you described is commonly used to measure the airflow in the intake manifold of EFI engines. For this principle to work with high precision it must have one part of the bridge in a protected and controlled environment. The sensing wire must also be placed in clean...

    Schematics Variable current 12v 60A to 0A

    Dazza, Yes, a walk through was what I meant. Sorry if I was blurry. I noticed that you are charging the 12V battery from the alternator. This alternator is at the same time used at up to 24Volts, am I on track? Q2 will not survive the current here I am afraid. :o I would be better to have a...
