I have a concept for a small control board that will act purely as a communication interface; the brain must be a microcontroller and every line on the board will ultimately speak SPI. I need the complete journey covered—from schematic capture through to a working prototype—and a simple companion application that can configure, send, and read data over that SPI bus. Hardware I want you to select an appropriate MCU, lay out the PCB, generate the BOM, and produce production-ready Gerbers. The board will only need the essentials: power regulation, the MCU, an SPI header, and whatever discretes are required for reliable signalling.

I want to decide on the most appropriate semiconductor switch for a new switch-mode power supply design, with switching speed as the overriding priority. Although I initially considered a thyristor, I’m open to any device—MOSFET, IGBT, BJT or another alternative—that demonstrably outperforms the rest once the figures are on the table. Here’s what the work entails. First, analyse the SMPS topology and its expected operating conditions, then shortlist realistic candidates and justify the final choice in terms of rise/fall times, turn-on/turn-off losses, and any ancillary gate-drive or snubber requirements. Once the device is chosen, run a full simulation (LTspice, PSpice, SIMetrix, MATLAB Simulink or equivalent) that shows switching waveforms, efficiency trends over ...
I need a COMSOL Multiphysics model of a high-frequency transformer that couples the electromagnetic and thermal physics so I can focus on thermal stress impacts.

Hello, I am currently off-grid with a 8.85kw solar array and an incapacitated SolarEdge Inverter. The contractor that did the installation back in 2019, not only put in an earlier model of the inverter, but assured me that it would work with a battery back up in the event of disconnection from the grid, which it does not. I found this out when Duke Energy disconnected me after raising their rates and somehow setting me up to be in their debt rather than they in mine (I over produce a lot). This, after returning from being months away taking care of my elderly mother after an operation. I am looking to take a more do it yourself route this time, with a new inverter and battery installation (I will buy the equipment after we consult on viability, price, etc.). This, with an electrician that ...
