From PIC Atmel328P battery powered with a maximum capacity of 4.5V and a minimum of 3.5V I have to operate a 12VDC valve. I have to charge a 4700uF electrolytic capacitor and then operate the valve with relays. At the moment I made a charge pump but it is very slow, it takes 2 minutes to bring the voltage to 12 volts from 3.5 volts. Anyone have a more efficient solution?

To open the treasury, the user must enter a serial binary password of 6 bits. Each bit is entered with a manual pulse at the input CLOCK. If the entered password is correct, the output LOCK is logic 1 and the treasury is open (you may use a green light to indicate the action). The treasury will remain open if the value at input DATA is still 1, but if the user enters a 0 at input DATA, then the tr...
