    Help me build a voltage monitor

    Hi, I need help. I have no idea how to build this one. I need a circuit that can read a voltage drop of 9V or below and flip on a relay, than turn the relay off when it reaches 24V to 30V. The voltage input source is 24V which could be reduced if necessary. Any help is appreciated. Thanks ROB

    How do I convert a square wave to a sine?

    I have 24VAC(input) being stepped up to 115VAC(Output). My oscillating circuit output a square wave before going to the stepup transformer. I trying to solve this problem be converting the square wave to sine before being stepped. By-the-way, the amperage is some where near 80AMPS. Can anyone...

    Pulser Circuit needed

    pulser I like to start by saying that "I'm a AMATURE". Now that's out the way. I need some help. I have effectively designed a water fuel cell the splits water into Hydrogen and Oxygen. The design works just great, but I need to send a pulse to the electrobes so that I can tune the device and...
