Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.75,217 értékelés alapján az ügyfelek 4.82 / 5 csillagot adtak Electrical Engineers szabadúszónknak.

the jammer should be portable and small and should identify and jam coming frequencies from 0-100hz. and it should cover a long distance.
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 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)
Need help with energy calculation
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...
It is a probe card with simple components like Resistors and Caps and LDOs and some switches. There is one BGA component microcontroller and we need somebody to come onsite and help with testing/soldering rework as and when needed.
I need an electronic wristband product that can recognize the voice of the wearer and can record the speech and can send that information to a mobile app using wifi connectivity. Timeframe: 1-3 months
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?"

Circuit should be of 4inch by 3inch with memory card (memory card cannot be acessible from outside it should attached with pcb inside its case,hence we cannot remove from outside so there should not be any slot ) Feature of wifi and bluetooth. power supply 3.7v 3200mah rechargeable battery, TFT and endoscope camera. TFT comes with 54 pin details will be shared and camera comes with 4 wire selection of microcontroller should be affordable endoscope camera should be used for streaming live video. endoscope camera(camera comes with its own module ), no need to develop extra components for it . camera should be drag outside with wire away from the pcb (length of the wire will be of 8 inch). there will be on/off button ,backward and forward button, wifi button. programming required for run...
Looking for Altium PCB design professional, who can design PCB from the schematic, and prepare the BOM list for the SMPS power supply. Since it is 400V DC applications, the PCB should design suitably in professional way.
I need a code for arduino and the language is c++ for this project: Our project is an automated pillbox: It has arduino uno wifi, LCD I2C, keypad 4*4, buzzer (alarm), 2 IR sensors, 2 micro servo motors. 1- the patient will set the pillbox he will enter date/time. 2- he will choose number of medications (1 or 2). 3- he will enter the time and number of pills for each medication. 4- when it’s time to take medication 1 alarm will go on until the patient press the button on the keypad. 5- the door of medication 1 will open using micro servo motor. 6- there is IR sensor inside the compartment of medication 1 to sense the medication has moved or not. 7- the patient has to conform taking the medication if yes number of pills for medication 1 will reduce by 1 and upload to the cloud. 8- aft...
