Электротехника Jobs

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.

    Arduino code 6 дней(-я) left
    ПОДТВЕРЖДЕН

    Write 4 wheel differential drive control code for a robot having 4 motors using BTS9760 motor drivers and My1016z3 motors. The robot will be controlled using flysky remote transmitter and arduino will have its reciver. The code should be based on kinematics and equation of motion. The required maximum speed is 70rpm and motors have a rated speed of 300 rpm.

    Build a EMG sensor to measure left and right fingers movements. 6 дней(-я) left
    ПОДТВЕРЖДЕН

    I want to build a system that can measure the movements of fingers based on the EMG signals. Ideally the system should be able to diffrentiate between the fingers and can records movements of multiple fingers simultaneously. If that is not possible than it should be atleast record the signal so that we can do analysis on that afterwards. The price can be negotiable but there will be milestone for every steps that we will discussed later. If you have read the description till here type SIGNALS before bidding.

    Thermal management project 6 дней(-я) left

    Simple thermal project. Two disks one made of copper it is water cooled and on top of that same diameter molybdenum disk is place. The molybdenum disk is exposed to high temperature plasma. The top surface of the molybdenum should be reading 950C and the bottom surface of the molybdenum is cooled by the copper disk. The copper is water cooled where the inlet temperature is 22C and outlet temperature is 25C. We need to simulate the thickness of molybdenum required to maintain the top surface temperature of 950C and also profile the variation of temperature center to edge of the molybdenum disk (top surface)

    Piezoelectric Simulation 6 дней(-я) left

    There is a schematic diagram of a performed experiment with PZT-5H discs arrangement with all the setup and equipment. In the experiment was performed in a busy road where only 2 wheeler vehicles were allowed to pass with a particular speed and time range and all the factors were recorded by respected sensors. We have all the data. Need a simulation based on the experiment performed on these points in mind. 1. All the parameters are needed, 2. If performed in ansys will prefer if the work is done in 'piezo and mems' extension for voltage parameter if possible. 3. Will prefer to the simulation to be as close to experiment as possible. I am open to new ideas or discussion of simulation if needed. Even further discussion if needed can be done.

    We have recently had a PCB designed to operate with BQ34Z100PW-G1 for gauge and BQ24170RGYR as our battery charging circuit controller. The circuit does not seem to be functioning with the code we currently have. We have tried a couple different solutions but realize we are in need of someone who is familiar with both parts, hardware and software designs. We can provide the circuit and all of the specific information needed to view where we are with the design. We would be able to share the current code we have for the devices, as well as we have the ability to help with debugging and trouble-shooting the physical circuit if needed.

Larger capacity cells will be investigated and used as they come available. They are housed in a nylon case and are wired in series having a centre connection for charging, there is no protection circuits in the batteries. They plug into our drones and controllers and will be plugged into the charger as required. The chargers are to accept either two or six battery packs and are to work with any number plugged in. We expect to be able to plug in up to six 2S battery packs which could be all at different charge levels and each will be balanced and fully charged on completion. An led showing fully charged will light on each pack when this is accomplished When ...
