    I need an electrical engineer who uses SolidWorks or other CAD software to design the circuitry for an On/Off switch to control a small 1/4 hp 115/230v AC motor. I also need to to assist me in finding a supplier for the basic materials. If successful I would like to hire you for more easy -but plentiful projects.

    Hello, I have found a circuit board drawing online that I'd like to have made into a virtual breadboard using the software at http://www.virtualbreadboard.com, free to download. The circuit drawing I found was probably made in paint, there is no author to it, and hence no support. The original circuit was made with three levels where the designer soldered IC chips on top of each other. I don't want to do this. I just want ...

    I need a small daughterboard designed. It is very basic. PCB Size +- 3x3 to 5 x 5 cm (3x3 will be best if you can make the terminals fit. Terminals need to be1/2cm x 1/2 cm. Center of the board, a 8 pin IC socket The board redirects the following pins to (looking from the top): - Pins 8 and 4 (top) - Pins 7, 6 and 2 (left) - Pins 1 and 5 to the (bottom) and - Pins 3 to ...

    I need a device which is able to gather data from an accelerometer and a RFID reader. It should only activate when moving. If it moves, it should start transmitting a data stream, including the data from the accelerometer and the RFID reader via bluetooth to a connected bluetooth device. Thus I need the device to contain the following components: - Bluetooth Module - Accelerometer - RFID - Battery (needs charge indicator) The device should be able to read data from RFID-Sources within a ...

    Currently, I have a prototype product that runs off an Arduino Uno, which controls two solenoids and 2 Mosfets. There are 2 analog potentiometer inputs, a push button, a microswitch and an LCD display. The prototype functions flawlessly and performs exactly how I want it, however, I want to add wireless communication (BT or WiFi) with an Android Device. Then have the Android device perform the functions of the 2 Pots and the push button as well as display the ...

    My team and I are developing a brand new FPGA. We need to know what kind of circuit designs we need to implement so that we can program the device easily. Altera Quartus II seems like a great software package for this type of chip programming. There are two major methods used by Quatus to program an FPGA: JTAG programming (volatile) and Active Serial programming (non-volatile). We need to know more details about these methods. First, describe the method of ...

    Design and implement an inverter circuit in LTspice with the following specifications. Inverter which can be used in solar power. Input power = 5KW Input Voltage = 24V DC Output voltage = 120V AC (Sine wave) Output Frequency = 60Hz Any device can be used such as MOSFET or BJT but switch is not allowed. Please give appropriate reason why the specific device was chosen. Simulation in LTSpice is required(most) with proper input and output. (Please apply only if you are confident and ...
