You will be given a piece of schematics which you should analyse and give the details explanation of how it works to me. Very good or excellent knowledge of following fields is mandatory(since schematics include those): 1. NUMBER ONE: fluent english 2. Transformers (common terminal on primary side transformers, protection on primary side, filtering on secondary side, driving transformers with short pulses with big time pauses between) 3. Op-amps (used to adjust voltage and provide sufficient amount of current) 4. MOSFETs (driving them with microcontroller, understanding turn on and turn off times & how to reduce them, reducing ringing on gate, ) 5. Darlington pairs (using to limit current/voltage) 6. Microcontrollers (GPIO specs & capabilities, especially output) 7. PCB layout In brackets there is just short overview, more then that is needed. The project will be done in few steps: 1. I pick freelancer and send the schematics. You have some time to analysis. 2. We have our first call/chat. I have some time for analysis. You have some time for PCB layout tips. 3. We have our second call/chat. 4. You help me pick given electronic components. This explanation will be given to me in form of call/chat. We would have two calls/chats. At first call/chat you give explanation, I ask some questions. Then I got some time for analysis, afterwards we have another call/chat where I ask more questions and where you give me layout tips and recommendations(no need for you to do the actual PCB design). I am located in time zone GTM +1. I think this is maximal 2hours of call/chat and wish to have this done in one day.
