R Russlk New Member Feb 22, 2004 #22 The power in the 100 ohm resistor is about 800 mW, so yes use a 1 watt resistor. Also increase the 10K to 1 megohm for better efficiency.

duffy Well-Known Member Feb 1, 2009 #25 What the - ? Russlk, are you trying to drive the coil through the transistor's base???
jpanhalt Well-Known Member Most Helpful Member Feb 1, 2009 #26 This thread is almost 5 years old. I doubt Russlk is still trying to solve that problem. But then again, maybe he is persistent. John

M mujeeburrehman New Member Feb 1, 2009 #27 you can place a traic at primary of transformer and a pic should control this traic trhough opto isolator MOC3021. pic should control phase angle according to battery condition and current at output. but i have no code of pic . thanks mujeeb
