Need someone with Eagle PCB skills. PCB board already exist, but need documentation support

I have several PCB's that need coordination of assembly through a board house in China. The person I select needs to have experience finding lower lead time parts and designing new parts with lower lead times. I am needing to find a consultant that can help coordinate all the files to the 'board house's' liking and either identify alternative parts or redesign several parts to get my lead time to less than 90 days. Main tasks will be coordination and project management. I wouldn't say speaking Chinese is a 100% requirement but could come in handy. I would like the Freelancer to be able to finish the first project by Monday January 23rd at 12:00 pm CST

I need someone to create a design of a pcb that generates pulses that turn on and off a magnetron for my project. basically you have to use a voltage controlled oscillator which controls a vacuum valve and modulates the high voltage frequency of the must be controlled by a pic.

The aim of this project is to design a power supply that can generate 0-10V and source a current of 6A, has a small size and has a low number of components. The input of this supply would be derived from a 12V source. The control of the Power Supply is open for discussion. It can be based purely on software (digital communication between this PCB and the control PCB) or voltage-dependent feedback (ADC/OpAmp based on this PCB, with the control signal generated on the control PCB). The input 12V is biased at -40kV, and therefore this PCB will be floating at a potential of –40kV. Any mode of communication that is not affected by the fact that this PCB would be floating at –40kV can be implemented. Ple...

The work consist in modifying an existing 3D model of a small enclosure (110x50mm) for electronics PCB. The enclosure is made of two parts: the base part and the caps that clips onto the base part. The electronics is located inside the enclosure. The 3D model was initially designed with Catia and later imported to AutoDesk Inventor for further modifications. Before starting the project, it will be decided if the existing 3D model have to be modified or if it is needed to do reverse design of the existing 3D model before modifications. The model and documentation of the modification will be provided later after discussion. Thank you

We want to place a project which requires a final product. This is not one man's job. A team or a group of people can do this task. The project is to design an IO (Input and output ) module. Modbus TCP/IP protocol will be implemented. The device will run Modbus protocol and the user can read an input through Modbus. same way output will be available on hardware and the user can set output value using Modbus. the module will have 16 Input/output points and the user can select which port will be input and which port will be output by using jumper settings on PCB. More detail is in the attached document.

I need some help with CCtalk and to create an interface for a coinchanger. This is a project that is very close to what I want to do: It does not have to be arduino. ESP32 is an aternative. PIC another. I have some Arduino skills and are able to create the setup in Sweden. Some of the development will be thru TeamViewer. You need to have a CCtalk host to be able to verify your work. I will copy your work and apply it to a Comestero coinchanger. The task is to have 4 buttons. * 10 SEK * 20 SEK * 50 SEK * 100 SEK (option is 5 buttons and 200 SEK) When a button is pressed the coin value is sent to the Comestero coinchanger and 20SEK = 2 tokens from the coinchanger. The buttons will then be replaced
