Here I am making a Ni-MH battery charger which works from AC 230v. It is a SMPS base circuit. SMPS is a better alternative for the transformer based power supply. Here I designed a simple SMPS circuit based on a single transistor. The transistor is act as the oscillator and also as the driver. This simple SMPS provide sufficient voltage for the battery charging and also there is a full charge indication LED.For the complete making process visit my Instructable,
