Desain Sirkuit Jobs

I would like to hire a freelancer to design a cooling system that dissipates heat from rechargeable batteries. MOFs, a metal foam material that absorbs water, wrap around lithium-ion batteries for electric vehicles. As the battery heats up, the water in the MOFs evaporates, taking the heat away and dissipating heat. The whole process is simulated by simulation software, and drawing a conclusion. Heat dissipation under different discharge power (3c and 5c) needs to be simulated. The Freelancer will be responsible for designing and implementing this system, using the evaporation principle to dissipate heat from the rechargeable battery. The Freelancer should have experience in designing cooling systems, and should be experienced with utilizing the evaporation principle. The relevant papers a...

It should be portable (running on battery) and should have an auto-cut option once the temperature reaches desired value a small motor for stirring the water. None of the mechanical components fall under this scope. Just need off-shelf components to design a circuit.

I am looking for a custom battery charger that is specifically designed for Lithium-Ion batteries. Additionally, no AC adapter is required and the charger won’t require a universal voltage input. The charger will be used to charge scooty and e-rickshaw batteries. I need someone who can design an effective, reliable and safe product which can serve our needs in the long run. For more details i am sharing my all charger requirement list, if you cna complete any of them then contact us.

I have a board working on 5v, I am looking for someone professional to add a DC to DC 5v to 12v step up converter for one unit only on this board. I need to be able to disable and enable this converter by using a sort of a jumper/switch. The kicad, BOM, CPL, and gerber files are ready. I am expecting the freelancer to edit his modifications into these files and make them in the correct format for JLCPCB order.

Buen dia German te escribe Alejandro Herrrera tengo 2 proyectos el primero consta de realizar la ingenieria inversa y/o actualizacion de componentes para simplificarla o crear una copia. el segundo es el diseño de una tarjeta pcb, me gustaria realizar 1 videollamada para platicar y ver la forma en que podriamos trabajar.

I want to create mobile charger on which we can set charging configurations

Hello, My task is about to design charging and discharging circuit for an fuel cell voltages. I.e., 5 charging stages with 1 discharging circuit varies with higher voltages 240V to 480V. I already designed the circuit but I need to make some changes. So I need help in that.

Want to design a circuit diagram for a controller with functions like inbuilt voltage regulator, temperature control, tens, pemf, photon lights etc

We are looking for a skilled freelancer to design a simple Bluetooth circuit that can be integrated into a quite small device. The circuit should be small and low power, and should be able to communicate with a smartphone or other Bluetooth-enabled device. The circuit should be designed to meet the following requirements: • Bluetooth 5.0 or higher • Low power consumption • Compact size • Ability to communicate with a smartphone or other Bluetooth-enabled device. The freelancer should have experience in Bluetooth circuit design and be able to provide schematics, PCB layouts, and any necessary firmware for the circuit. The circuit will be integrated into a smaller device, so the freelancer should also be able to provide guidance on how to incorporate the circuit into...

Redesign Eagle PCB 4 layers. The total components are less 70 parts. The Library is in exist. We did add 2-3 new components.

Design an induction heater driver circuit (including schematic) powered directly from 230VAC (without needing a separate DC power supply), which can drive high frequency AC (>10 MHz) through a ~12 mH work coil to heat its core as quickly as possible (red hot in <5 seconds at max power). * Max power shall be limited to 3kW, to limit the current at power source to 15Amps. * Inductance of the work coil will remain constant during operation. * Circuit shall only include ordinary components available OTS (i.e. no specialized/custom components). * Circuit shall be able to operate continuously for at least 600 seconds at max power. It's OK if the components need ordinary active cooling. i.e. Should not require specialized cooling like liquid nitrogen. * Bonus feature would be if the c...

Create schematics and PCB layout based on the existing project design. The PCB should be designed in a way that it is easy to assemble and manufacture. Pick an appropriate microcontroller based on the requirements of the project. The microcontroller should have enough processing power and memory to handle all the required tasks. Consider factors such as cost, availability, and ease of programming when selecting a microcontroller. Add a gyroscope to the design. The gyroscope should be selected based on the required range, sensitivity, and accuracy. It should be compatible with the selected microcontroller and should be able to communicate data to it. Consider adding an accelerometer to the design, if required. The accelerometer should be selected based on the required range, sensitivity, an...

However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routing of electric...
