    The ciruit is a high current fan controller. I'm seeking a qualified/seasoned professional to provide an in-depth review of my circuit design and layout. There is a problem with the design. The driver sometimes doesn't turn on when triggered. The circuit works as follows: A mirocontroller has a triger input Once the input goes high, the MCU outputs a PWM that is fed to a gate driver, that in turn powers the gate of a high power mosfet. This is how the fan speed is controlled. The task entails: - Evaluating the current state of the design, layout and circuit components. - Providing fresh, actionable insights to improve the overall function and efficiency of the circuit design. - Go through the circuit layout and suggest possible tweaks for enhanced performance. - E...

    Arduino control of two fans with 25Khz PWM at 12 V หมดเขตแล้ว left

    We are looking for an expert freelancer with extensive knowledge of Arduino, to create a quick prototype based on Arduino board (or similar development board, like Raspberry Pi), that will be suitablle to independently control two fans witha PWM signal with 12 V, carrier frequency 25 Khz. You will be responsible for selecting the correct arduino board, the necesseray accessories (like shields or amplifiers to reach the correct signal). This project is better specified in the attached description document, the description doc was orifinally created with labview in mind, that later proved unsuitable, but I think you will quickly get the idea. We need this project delivered in 7 dayys, that is, we need a first demo within 4 days, and remaining time for revision. Demo can be done at ...

    Solar-Powered Pulse Charger Circuit Design หมดเขตแล้ว left

    I'm on the lookout for a skilled and experienced circuit designer who can create a pulse charging circuit for a 12V or 24V battery. This circuit will need to be compatible with a 500watt, 44V, 12 A max solar panel. Ideally, you should be proficient in: - Designing circuits with a Pulse Width Modulation (PWM) generator - Building circuits that trigger a Mosfet, IGBT, BJT, or an equally efficient transistor - Engineering circuits with a charging voltage exceeding 100V - Regulating frequencies in the range of 0-10kHz. - Efficiency is crucial here. Don't want too much wasted energy in heat or heat dissipation, or waste half of the energy if it is 50% duty cycle. This is an opportunity to demonstrate your in-depth knowledge in electronics and circuit design. A robust understa...

We need to be able to communicate WHAT the CONCEPT of the site is AND GIVE THE ASSETS, and you be able to take it to the finish line from there by creating the look and feel and functionality (we have programmers that can help you with that part --- but you must be able to convey what those design elements are and produce them). We are looking for a "developer/builder," not an "assembler." We need: 1. Ability to creatively visualize data (text/numbers) 2. Creatively combine data with imagery. (While not expected to create imagery, understanding how to creatively lay out imagery with data is crucial) 3. Knowledge and ability to research current design trends and technology 4.
