CIRCUIT DIAGRAM Tune the variable resistor RV2 to cut off the charging after the desired level of voltage. For a 12V lead acid battery, charging cut off on 13.8 volts will be sufficient. TRANSIFORMER should be 14acV -15acV . and at least 5AMP BR1 (BRIDGE) Rectifier. CAPACITOR C1, C2, C3 should be 1000uF/25V or greater. RV1 … Read more
The LM317 is a voltage regulator and it has some maximum ratings. One is current, “in excess of 1.5 A” means that it can supply a bit more than 1.5 A, so a 1.5 A application would be OK.
104 CAPACITOR The 3 digit code 104 written over ceramic capacitor indicates its value. The first two digits (10) of this code are first two digits of capacitor value and third digit (4) gives the number of zeroes to be added so as to get capacitor value in picofarads which is 10,0000 pF or 0.1 … Read more

555 Timer When a 555 Timer is configured in bistable multivibrator; its output is either high or low logic signal. Here we use the simple logic that when trigger pin is grounded, output is a high logic signal and when reset pin is grounded, output is low logic signal. The circuit for a bistable multivibrator … Read more
