Hello, i have seen you proyect, and i would like to know if the IC is only to make a square wave (and the negated) to control the two LM358? what level of signal is at the output of Q and /Q? could it be maded with a simple n555,R and C circuit? What will happend if i set to the LM358 a sinusoidal signal?coult it generate a SIN signal at the transformer?or does it work as a comparator and it gets 12 - 0 - 12 - 0 (Q=1, Q=0, Q=1, Q=0)? and what about to set the Sinsuidal generator after LM358 and driving the MOSFETs?The Sinusoidal must make only one Pi ,i mean PI=3'14,the half of the period, to generate a half wave each time with each LM358 Thank you Very Much. Great proyect ;)
