This a project using a NE555 timer chip. This circuit above that i drew, shows an oscillator circuit which would boost the input voltage and double the input voltage.
On the left is the the circuit that i made, and it works well, but it can only handle low power loads like lights, i added a inducter which is the black thing to smooth out the noise on the output. (Inducter put between the output capacitor and the diode.
