    Hi!
    I have to build some circuit using operational amplifiers. Any suggestion? I found on web few projects, like Cell phone detector, water level controller etc. but I's not interesting for me :) It may consist of microcontrollers too. Thanks in advance.

    Well there's the rub. What sort of thing WOULD interest you? There's no limit to the projects out there. The key is finding something that inspires you. Radio? Solar power? Magnets? Computer logic? Robotics and sensing?

    You could build low power transistor amplifier.

    @wayneh,
    It shouldn't be so sophisticated, like robotics :) Circuit must contain at least one opamp and it should't be so complicated.

    That's fine - complex systems like a robot are built up from smaller components. You might have an op-amp that helps sense a robot's surroundings, for instance. Maybe a thermometer or thermostat. Line-following robots are pretty darn simple.

    I'm not advocating for any particular project, just that you should think about what general area might interest you and then folks here might have some thoughts.

    Transmission of music using IR or white LED.

    I would like to build current source. Can you suggest me some good implementation?
