I am designing some electronics prototypes.
I have some basic schematics but need help to correct or redesign them prior testing.
Experience with PWM mosfet push-pull power supply transformer and piezo transducer is a plus.
Contractor may need to find appropriate parts sources (Mouser or Farnell, web search).
The work will be iterative and made of small updates (30 min to hours chunk)
Are you interested ?
