here i attached the diagram i have build.
what i'm sure are.
Occilator works OK
Mosfets are OK ( i Have tested each one seperately ) but only one of them which drived by NPN transistor gets hot in a short time ( 1-2 minutes then after burns ) both are fully turns on and off.
i've got to mention a thing is that as for testing i have connected 2 leds
and lit them like a flipflop i have observed that the one fed via NPN transistor lights brighter then fed by PNP transistor. assuming PNP transistor causing more voltage drop then NPN ones.
Since Mosfet drived by PNP transistor works grate i just think ( it might be wrong ) may be i should put grater resistor to the gate of the mosfet which
fed via NPN transistor ( Burning one ). i'm not sure that this will be the solution. i'll give it a try. or i should use another occilator
any suggestion please
thanh you.
