i need a a complete HW/SW solution to make a wifi microcontroller board that transmits/receives digital signals and connected to a camera. the signal should be received at our server with a web page controlling the board and the camera

I want an intro on electrical physics

I plan to use a TPS54283PWPR from Texas Instruments in a project I am working on. I need an experienced engineer to help design my schematic and to ensure I have not made any silly mistakes (before I commit to the PCB) - alternatively, if this proves to be the incorrect part I will need help to identify alternative. All I need is a reliable DC DC converter with 24vDC input and output 1 = 5v at about 2 amps and output 2 at 3.8v at about 1.5 amps (I'm struggling with the maths in the datasheet)

Design/build from ground up 6,000s.f. church. Need MEP engineering.

I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for re...

I would need Simple circuit design that does the following 2 tasks for a 5V arduino pro mini 1. Power the Arduino (5V) from a car Battery (12-16V) including protection circuit. The Arduino should keep Power for about 5 seconds after the Battery power is switched off 2. Take a 12-16 V square wave and reduce it to a 5V Square wave via a opto coupler so it can be used with a digital input I don't need a PCB Layout

I aim to enhance my research paper by incorporating renewable energy sources, specifically solar and wind, as well as an energy storage device, such as a BESS. I plan to use Grey Wolf Optimization as a technique for optimizing the variability and uncertainty of these sources. If a different controller can produce better results, I am open to considering it, but I do not wish to use neural network or fuzzy logic controllers. Additionally, I may include filters in my analysis. My ultimate goal is to improve upon the work outlined in my research paper by integrating renewable energy sources. Can you explain to me how the GWO code and simulation work?"
