Bid circuit designcông việc

If you are not an electronic engineer or have no clue or experience about audio amplifiers, circuit design please do not message, propose or bid. I need to design an all in one pcb board. I already have to schematic and design of the single ended class a amplifier. This amplifier design is working as we speak, a prototype design has been made (please see pictures) I need someone who understands power supplies, things like CRC,CLC, and can simulate power supplies and get the best overall design. An example has been uploaded. Ill need someone to be able to perhaps do a computer simulation of the power supply to design the best fitting one (this is optional) It will have dual bridge rectifiers, choice of capacitors, for thi...

I'm looking for a freelancer who can design an analog electronic circuit for me. I need a customized design, with the circuit size to be miniature. My project requires the freelancer to have experience using advanced design technologies and processes. Someone with an impressive portfolio of related projects and an ability to create modern, efficient designs are highly desirable. Additionally, knowledge of desirable safety measures and versatility in the design process would be a plus.

I need someone who can take my microprocessor project schematic circuit (done with PowerPoint) , convert it to a proper schematic diagram, suitable for getting PC cards made, get a few PC cards made, and assemble one board for my testing (I can provide the component kit). So.... needed is someone with experience creating and wiring PC cards. There may be a few board assemblies needed if the prototype works out well. I do the software. Follow-on production (if any) is TBD.

Looking to have this board remade with all its components. It’s very simple. Thank you

The preliminar idea of the project is to buid a device based on a STM32, that controls a 4 inch LCD screen with RGB interface, with 2 to 4 serial data signals and 4 to 8 buttons. Design using easyEDA and prototypes made by jlcpcb. All this can be modified by designer advice. The work is design and test of the PCB. More details: - The work is to design PCB and schematic - The circuit has a 12V power source - The LCD is not deciced, but has to be high bright, problably RGB888, to be decided - The serial data bus is CAN - The LCD probably has a backlight power voltage of about 15v - I decided to use easyEDA because I know it, but also to be decided - I decided to use STM32 because it has support for CAN bus and RGB888, but again to be decided Regards

I am looking for an experienced electrical engineer to design a simple component for me. The design should be in the form of a circuit schematic. While I have an idea of what I am looking for, I am also open to any suggestions and observations that the engineer can provide. The component should be of simple complexity. see picture for project. I need to know exact material to use to make this work. Unit needs to be as small as possible Components need to be low cost Light needs to stay on for short time after sunlight is removed from solar panel.

Attached schematic shows one circuit of 4 identical circuits connected end on end. Not shown is a single opamp buffer with 220R resistor and 2.2uF film cap on the output. The power bus is +/- 15v with ground. There are no pots on the board; wires will be soldered into three adjacent holes for the Boost/Cut pot--same goes for all external connections. The Q, and the a and b Freq pots, with be replaced with 2 RN 55 resistors connected in series to the wiper terminal from terminals 1 and 3. Not shown are 4 - 10uF electrolytic caps on the power bus near each circuit with 2.54mm centers. All of the resistors are Vishay RN 55, except the two 5.1k at the bottom which are RN 60. The 10uF caps are small bi-polar with 2.54mm centers. The rest of the caps are film with 5.08mm center...

A) Design of high performance signed 2’s complement 4-bit adder circuit using carry Look Ahead Adders. (See and ) In carry look ahead adders, the carry propagation time is much less than RCA (ripple carry adder). Therefore, the addition process is very fast. As you get more familiar with CLA concept you will understand why we need it for faster adder hardware. Study the ripple carry adder first to appreciate the objectives. You may use transmission gates, static or dynamic CMOS design. 1) Draw a transistor level schematic of the 4-bit CLA in Electric and simulate it in LTSpice. 2) Draw stick diagrams and Euler’s paths where appropriate to design. 3) Perform the Electric Layout with IRSIM. 4) Verify your design by

Solar panel requirement. When designing the architecture of a 1 MW solar plant, you should consider the following factors: System Requirements: Before beginning the design process, you should determine the system requirements, such as the energy production requirements, the available space, and the budget. This will help you determine the appropriate number of solar panels, inverters, and other components required to meet the energy production requirements of the system. Solar Panel Selection: The solar panels should be selected based on their efficiency, durability, and compatibility with the other components of the system. Factors to consider when selecting solar panels include the panel's wattage, voltage, current, and temperature coefficient. Inverter Selection: The i...
