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.Zaměstnat Electrical Engineers
We are an intelligent control company looking to implement our technology on an electric bike battery charger. We require someone who can design the charger, test it on batteries, and provide us with data. See the attached document for a general idea of what we're trying to do.
This project requires knowledge in power relay physics and arc suppression (TVS) techniques. We need a circuit to wrap around a latching power relay to minimize internal relay arcing during operation (make/break) for extended operational life. There are many conceptual ways of doing this such as snubber and varistor approaches, but we need specifics on products to use that are available today and their configuration. The relay in question is rated for 250V, 120A but we are operating in a 120VAC nominal environment with at most 60A full load. Datasheet of the relay can be provided. Expected life of the application/proposed solution is ~20 years with up to 10,000 operations over the life of the product.
I want you to build a Datalogger Hub based on an RTU, with sensor data reading (temperature, humidity, solar radiation, etc) via RS485, up to 5 direct sensors, or up to 32 sensors connected by a splitter. The Hub would need to be able to receive data via LoraWAN. All data would be sent via 4G/3G/2G to a server. The Hub would have to be based on low energy consumption technology, have a battery with autonomy for at least 1 month without using a solar panel. It would also have a built-in GPS locator. More information will be given later Data logger that uses the MODBUS-RTU RS485 protocol to communicate with sensors. This hub can be connected to a maximum of 32 RS-485 sensors and must be capable of collecting various sensor data simultaneously. The data logger features a built-in GPS posit...
Details would be share in chat.
The project consists of programming for two pcbs, developing an IPAD APP (Xcode programming) and programming a NEXTION screen (NX4827P043-011C) in the NEXTION editor software. More details will be given to the selected one. It is necessary to code in XCODE for the ipad app, the source code will be integrated into our main app.

This project will be to design test tools called breakout boxes in AutoCAD Electrical. The breakout boxes will consist of a metal box with two harnesses and D38999 connectors, and banana jacks and plugs for each signal on the connector. There are 16 unique breakout boxes to be designed, all similar in design but just varying connector type / signal count / box size. Deliverables will be pdf drawings and CAD files for the designs. I am not ready to move forward with this project as I am still working with the client to finalize details and requirements, so this post is to receive quotes and establish contacts for when I am ready to move forward.
Here I found a global planner code with A* algorithm from PythonAPI in official Carla, but there is no PythonAPI in coursera Carla simulator. I would like to implement this to coursera Carla simulator and make it work. This project need you to be familiar with carla and python.
Hi, I want a complete electrical design for my house. The design I want will be in a detail way with complete load sheet and BOM. I want an electrical engineer having experience in design field.
I wanna control 4 (12v) dc motors with the help of an arduino ad joystich in such away so that when we forward the joystich the 2 forward motors became active and as much we tilt our joytick toward right . the voltage in right motor fade down and our project car could move towards right same wjth the left one. And when we move our joystick backward our 2 back motors became active and same concept here also of right and left .
Hello! I need your help in our research. It will be very useful if you answer a few questions in Google Form . Thank you for your attention and time! with best regards, Aleksandra Yurina master student of Perm State University, Perm, Russia
We are looking for someone who can do the mechanical and/or hardware designing for our in ear wearable device. We can further discuss more on details if one is interested.
How comfortable are you in building exercise equipment? Also before proceeding we would need you to sign an NDA before we can release any files to you to review. We are looking to build a machine that encompasses several different exercises without the subject moving and without compromising safety of the exercises. These would be placed in medical facilities. Also would you be willing to jump on Zoom or some conference call to go over any specifics after legalities are dealt with? Thanks. CEO/Founder--Stephen Davis
