aluminum electrode

[yellowcat]

Does anyone now how I can make a controller to turn 2 volts on and off at different intervals? I want to use an alumium electrode submeraged in a salt water solution,but I need to be able to pluse the voltage on and off ,I need to be able to adjust the amount of time that the voltage is on or off.You are supposed to be able to make a lot of gas with this,but you need to be able to control the voltage(by turning it off and on) to control the amount of gas.I want to find out how much aluminum is consumed to make the gas and see if it is worth while way to produce gas for heat.
Thanks
