When you want to experience build Step up voltage DC to DC converter. I thinks this circuit basically the base certainly. By use 74C14 integrated digital number circuits are pillar equipment. In the principle at the beginning can modify 1.5V DC electricity pressures have to 6V DC. With the techinque LC booster up voltage. For other detail , see in the circuit and original website http://www.rowan.sensation.net.au/electronics/stepup.html better sir.
