Working on PCB component placement. This will take some time. As I also work full time, this work is mainly done in my free time at the weekend. Please be patient. Thanks.

Corrected final schematic with new symbol for C1 and drains of MOSFETS connected to the correct place.

A screenshot of the PCB outline with construction lines to ease component placing.

I am no longer doing any work on this as I am afraid of infringing copyright and intellectual property laws. If requested, I will destroy any schematics that I have produced so far (which have been produced purely for personal research/study purposes). Sorry if I have inconvenienced anyone or caused any disappointment.
