Elektrisk ingeniørvitenskap 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.

    ARM coding 6 dager left
    VERIFISERT

    Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

    I need a literature review on (Measurements of polymer permeability using NMR). So basically we need to understand the diffusion of polymer nanocompisites using NMR. In this case I have fumed silica and I incorporated it in HDPE (high density poly ethylene) and made a nanocomposite and now I need NMR to get permeability and diffusion characteristics.

    1. "idle" state: It is the state when the machine is doing nothing and is idle. In "idle" state, if power button is "on" then the state transition takes place from state "idle" to state "a" and the output is low. If power button is "off ", then the state remains in "idle". 2. "a" state: In state "a", if fill_water is 1(that is if the water gets filled) then the state moves to state "b" otherwise it remains in state "a". 3. "b" state: It is the wash state of the machine. In "b" state, if add_det = 1(that is if the detergent is added) then the state moves to state "c" otherwise remain at state "b". 4. "c" state: It is the rinse state...

    E Bike Rotor Coil Generator 6 dager left
    VERIFISERT

    I have a mechanism that can manufacture the rotors for the generator . I need the coils and the capacitor designed so the rotors rotate and collect the dc power renerated by the coils in multi capacitors . Then through the switch design this is released into the batteries as a charge . As one capicitor is discoraging another is charging . As there will be multi coils there must be multi capacitors to keep this process rotating . And it must be design for safety as there will be a lot of power being renerated and stored for release . This must be able to charge a 48v or 52v battery ok . Can you design if not i will put this back here to get others to design . But either way you must work with them to design capacitors and system to have the battery switch also switch output of capacitors in...

    I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...

    We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

    This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
