design a serial multiplexer system that'll allow a single UART to communicate with 6 remote UART. Communication will happen in both directions. We're expecting you to select components, design the circuit assuming 5/3.5 V power-supply already present, design the pcb and write simple C based board support package. End application is NOT expected. The challenge in this project is minimizing cost.

I need a circuit design & fabrication of a prototype unit to limit and dissipate high voltage spikes on a 600 VDC, 3.5 kW power system. A small wind turbine on my farm produces up to 3.5 kW, 600 VAC,3 phase power at wild AC frequency (0 to 200 Hz?). A full bridge, 3 phase rectifier takes the wind turbine output & generates 0 to 600 VDC, single phase, single leg, at varying amps, with some noise. If the rectifier output voltage exceeds 300, 400, or 500 VDC (switch selectable), the rectifier engages a load dump heater to dissipate excess power and control maximum voltage output. The rectifier's DC output is fed to a Morningstar Tristar MPPT Charge controller (Model: TS-MPPT-60-600V-48) so as to charge a 48 VDC battery bank. This $2,000.00 Tristar is extremely sensitive...

In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf,[1][2] denoted E {mathcal {E}} or ξ {displaystyle {xi }}) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf[3] by converting other forms of energy into electrical energy.[3] Other electrical equipment also produce an emf, such as batteries, which convert chemical energy, and generators, which convert mechanical energy.[4] This energy conversion is achieved by physical forces applying physical work on electric charges. However, electromotive force itself is not a physical force,[5] and for the current ISO/IEC standards consider the term deprecated, favoring the names source voltage or sou...
