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.Conforme as 80189, avaliações, os clientes avaliam nossos Electrical Engineers 4.82 de 5 estrelas.
Creation of a small PCB for charging and powering a single USB A port. What I would like to have designed for me is a PCB that enables charging of a 3.7v battery through USB C, and outputs power to something that can be soldered to a USB A IO. The USB A output will only be supplied power when a button is pressed, and power will stop being supplied after 5 minutes. The PCB will need to include battery protection, and deep discharge protection. In short, this PCB will be connected onto an already existing PCB, that should only receive power for 10 mins after the button is pressed.
We need an electronic circuit that can convert AC signal into a train of pulses of 250 V (offload). The output voltage should not be less than 200 V while on-load (short circuit) condition. the shape and duty cycle of pulses is shown in figure attached.
You must have the experience, knowledge and capacity to design and develop a multichannel Functional Electrical Stimulation hardware and multichannel EMG sensing circuit. You will also have to integrate diverse sensors and design communication protocols. You must have proven experience on working with AI on the edge.
I have a concept drawing done in revit 2018.2 model for 4 storey building. I am trying to get pricing for Electrical and HVAC in order to get an idea for financing purposes. Unfortunately the subcontractors do not entertain quoting the project without a full set of engineering drawings. Given the fact that it is only a concept model (which will most definitely change when architects and engineer get involved), I cannot spend too much. Please specify number and type of drawings.
Can you make pi loop bldc motor control application with ch32v307 risc-v microcontroller hall sensor six step algorithm? If you do, please make sure it is simple and with explanations. motor=24v-3a-2 pole driver=ir2110 hall sensor input=pull up
If you have a workshop and want to check the quality of the work and the goods used and if they comply with the standards and there is no cheating and give you ideas and guidance for the project I can travel and supervise the project and implement the work well from one week to the end of the project ….

I need to detect the number of rotations of a spinning magnet. I have measured the magnetic field strength oscillating around += 0.9 Gauss (see attachment). Most hall effect sensors with built in amplifiers and comparators don't have operating points in this range so I need to design one using an analog output hall effect sensor and op amp. However, I'm open to other design suggestions. Requirements: - Digital output indicating a rotation of the magnet - Low power (~50 uA @ 3.3v) - Minimal part count - Low cost part selection - SPICE simulation or some kind of verification of design Example design: Analog hall sensor (e.g. DRV5053) -> Amplifier -> Comparator with hysteresis (e.g. TLV320x) -> Digital output
Need to use multi-objective metaheuristic optimization and BF power flow. The radial distribution network needs to consider the uncertain power output of the DG. I need high level experts on this topic. Please don't disturb me if you are not familiar this topic. Thank you.
Hello there, I need your assistance in performing the load calculations and load distribution for a small task.
TI IWR6843AOP uses out of box demo that sends the radar data via serial. We need to change that to CAN FD.
It has a lot of rust damage in the battery area, will need replacing. Shouldnt be any other issues but a “tune up” of sorts is probably necessary.
We are a startup US company selling a custom product with an electric motor. We created an add-on device that receives CEC info from a TV and controls the motor with RF signals. We have all designs and firmware for our RF device completed, prototyped, and tested. The only part of the design we do not have yet is a 3D print file for the outer plastic housing. We are looking for an electronics manufacturer to produce our RF device for us. Small batches at first, but hopefully larger amounts as we increase sales of our product.
I want a matlab code that takes an input as either zero or one and encrypt it and decrypt it using hash message authentication code
I'm looking for some car canbus expert to find out a way to get wheel rotation from canbus OBD standard in order to work on all cars Or find out specific canbus frames for multiple cars I'm trying to get wheel rotation or ABS pulses from canbus If you don't understand the project or you don't know if you can make or not don't bid on the project
Need to vary current of a dc source from 10 amps to 70 amps in steps of 1amps. Design and development required for the same. Voltage is 220v dc constant
We’re assembling a multidisciplinary product development team to develop a new Robotic Cooker. We anticipate that this project will need the following areas of technical expertise: Mechanical engineering, electrical engineering, and industrial design. Musts: • Fluent in English • Work around EST time zones • Experience with motors (servos, DC, etc.) and encoders for robotic arms • Experience with Shafts and Bearings You are invited to apply as a member of this team. As such, you only need to possess some of the above skills, as there will be multiple specialized team members. Thank you!
I require someone to utilize the coolprop C++ Compiler and developed a pressure enthalpy chart for NH3. We need the C++ runtime to run a PC, which will communicate via Ethernet/IP (Fieldbus) to a PLC which it will read 4x Float tags required for the chart Plot.
1. Convert the system data to per unit on a 100MVA base. Use the generator 1 voltage as the voltage base. Present your results in a table. 2. Construct a Ybus matrix for the system.. 3. Enter the system data into Powerworld or MATLAB. Set your slack bus as Bus 1, and set the angle to be -30 degrees. 4. Solve the power flow problem, and compare your results to the table given below. Treat this as your base case system. Display the same data fields for all subsequence power flow results. 5. Compare the Ybus matrix from Powerworld with the one you calculated above. 6. Lower Pgen2 to 0.7 pu. Try lowering it to 0.5 per unit. What do you think would happen if th generator was taken off line. Comment on your results especially the voltage magnitudes and the total losses. 7. Explain what would be ...
I am going to reconstruct one paper of environment pollution forecasting using ANFIS. When you are only expert, please let me know. Thanks.
Need to code in C++ for Circuit in Electronics.
I need CC2530 firmware can work with ZHA installed on Homeassistant. I have CC2530 Z-stack firmware but I have some problems. I can't connect the device to ZHA. My firmwre works well with my custom coordinator. I can provide my firmware.
I need an RF amplifier. The modulated signal has a fundamental between 0.1 and 23MHz, and the carrier wave is 3.1MHz. Input signal is 500mVpp, and output must be 50Vpp. The load is 300 ohm. The power supply is 18 V VDC Heat must be managed with a small heat sink and no fan.
