here. A certain frequency pulses are generated with the 555 timer IC by using 1K, 10K and 560pF capacitor. The pin 6 and 2 of the IC is connected with each other makes the IC self trigger continuously and providing pulses at the output pin 3. A BD139 transistor is connected at the output of the IC, when each pulse is received the transistor become switch ON and save some energy in the 100uH inductor and when the transistor is switched OFF the saved energy of the inductor is fed to the 1uF capacitor through 1N5819 diode. Make sure to make all the component values same as written in the diagram, using a slightly different value can decrease the performance of the circuit.
