    Basicly the project is using the rogowski coil as the current sensor to detect load current send to the energy IC ADE7753 . I prepare to use PIC18 microcontroller to drive the IC and do the calculation and calibration. The real power comsuption will be shown on LCD . What I need is the C programming to drive the ADE7753 as well as the LCD.Where I used used PICDEM2 PLUS demoboard and self connected sensing circuit which followed the ADE7753 datasheet ...

    I need an electrical engineer to help design design a circuit for a new led bike light I have developed. I will provide operational expectations an documentation of the current off the shelf parts used. The project will consist of a rechargeable Polymer Lithium Ion battery pack, charger, 12 LEDs, and a DC to DC step up from 3.7v to 12v, and a on/off switch. Deliverable would be a finalized circuit and list of components. --- Skills: design, engineering

    Hi, We are looking for someone to design a circuit to to monitor and control electrical devices (Analog and Digital) remotely using GSM modem/phone. A measurement device (CT) will give an analogue output current of 1 to 5A this signal should be converted into a digital signal and multiplied by a certain factor. The user should be able to send a query SMS and the circuit should respond with the current reading and average reading over the last hour ...

    This is the write-up I create for the project. For this part, I need the circuitry designed. If the price is right, I'll have the PCB created as well. The parts listed at the bottom of the brief are for me, not for you. But you can look at them to get an idea of how the project will look. ------------------------------------ This circuit board will be the core part of a device that will act as an audio source selector ...

    I do have one person for this position, but I would like to have multiple. If you have great skill programing microchips and developing circuits this may be the job for you. This job may not pay much, but if you complete it successfully you will have much higher paying jobs coming your way. In this job will be creating many tiny programs for a microchip. That microchip will be added to a motherboard to influence the way it works ...
