a Led Light assembly done inside a useless mobile charger case.
Steps-- first disassemble the charger and take out the inner circuit, use hex screw to open the chargers of samsung. nokia, lg mobiles.
Second- made 4 pairs of holes , total 8 holes for the legs of 4 Leds. put them and solder as per diagram.
Third- connect the capacitor 0.22uf/400 volt & 1 Meg Ohms Resistor in parallel, here the resistor is used as a shunt resistor to discharge the stored current from the capacitor after the AC switch off. its a safety measure to avoid high voltage shock.
Fourth- connect 1 K ohms resistor as shown in diagram.
Fifth- assemble with screwing the case.
Sixth- connect with ac source 220 volts & Voila!!!!!, there is Light !!!!!!!!!!!!
