HI!
Your project basically consists of 3 parts:
* Zero crossover detection; ouput to
* 555 in monostable mode with variable pulse length; output to
* H-bridge powering the coil
I can design the circuit for you and send you the schematic within 12 hours of you hiring me. My bid cost includes required research, circuit design, schematic building, part selection, and Bill of Materials generation.
Needless to say, I'm an expert at this work and have earned good reviews so far.
However, before beginning the project I would require a 5 GBP milestone to be completed to make sure you are an honest employer, as you do not have any reviews yet. Sorry for this, but I have been let down in the past.
Hoping to work with you at the earliest.
Regards,
Pranav
