LED DC to DC boost converter from 3.7 Volt to 12 Volt using 555 Timer and Mosfet S80

Very interesting LED boost converter to drive 8 volts LED using 3.7 volt 18650 battery. The circuit is powered by 555 Timer chip to drive N-Channel Mosfet S80. The inductor value is around 220 uH - although this is not the very best of circuit but it does amplify 3.7 volt step up to 10 volts DC to DC boost converter. The setup is quite simple where the 555 timer drive the Mosfet S80 (N-Channel Mosfet)
