    • Standard components - All components used are available online or at your local electronics store.  
    • No SMD components used - Only through hole components used, making soldering and replacement hassle free.  
    •  Cost effective - This amplifier can be made in a fraction of cost compared to similar amplifiers available in market. 

    Brief Description of Circuit

     Mains Power is applied via 0 - 15 volts transformer, it is rectified via D1,D2,D3,D4 Diodes and given to U1 voltage regulator.

    The output voltage of U1 is set between 15.5 volts to 16.5 volts via RV1. 

    12 volts Battery is charged by this constant voltage variable current through D5 and R4. 

    when the Battery Voltage reaches 15volts, zener D6 turns on transistor Q1, cutting off U1 and stopping charging current.    


    The LED's are Controlled by LDR, in light LDRs have low resistance so Q3 will not turn on.

     in Darkness LDRs have high resistance so Q3 will turn on the LED lights. 

    Always keep the LDR in the Shadow of LED's. LDR sensitivity towards light / Darkness can be adjusted via RV2.
