    This project aims to control a Gyroscope, having motors in 3 axes. As the delivery of this work, I would like to obtain: - Complete technical drawing. - Arduino program, containing comments for understanding the flow. - List of recommended components, cables, boards, motors, other elements deemed necessary for future purchase. The idea is to have two Servo Motors and a DC motor. The DC motor in the center, axis C, image attached, being powered by a current that will pass through a Slip Ring Connector B. Such Slip Ring Connector turns from axis B, which represents the second servo motor, also powered by current that will pass through Slip Ring Connector A, coming from A. The DC motor will be activated as soon as the Arduino is connected to the power source. Servo motors will be driven clo...

    Hi, We need a compacthigh-quality Qi Wireless charging receiver for our project. Currently, we are using the following cheap version, but can not trust it for a long term project. We are interested to build one based on Western Chips (eg: TI, ST .....) with good documentation and test data. Your responsibilities: 1. Find the best chip for the purpose 2. Designing the boardcoil.... 3. Assist us with finding the PCB manufacturer who can provide all components and ship the final product. (We do not want a design that could NOT be manufactured) The design is very straight forward and could be based on the best practices and example circuit provided in the chip's data sheet. The only matter to note is: in our product 2x Qi receiver modules will be used. The output of these are di...

    Verilog Coding 5 日 left

    We need to program a FPGA board using verilog code with XNOR, Multiply, shiftleft and add modules that can run on the board using different switches. When we compile the code there are no errors but when we try to put the code onto the board it is showing only zeros so we think that there is something wrong with the XNOR, Mul, shiftleft or ADD modules. I will attach all codes and the manual for the project below, thanks.

    I need a circuit design. In my application, a 9v battery supplies power to an Arduino Uno. The 5v output available on the Arduino is used to power a GPS module ('GPS Module Receiver, Navigation Satellite Positioning NEO-6M' available on Amazon; image attached). The GPS module has a Pulse Per Second (PPS, one cycle per second) pin that is active only when the module has obtained a fix on a satellite set and begins tracking. Before tracking begins or when tracking fails, the PPS pin is at zero volts. When the PPS pin is active, it produces a square wave pulse train, 1 Hz, 3.3v amplitude and 100ms duration of each pulse. The supply voltage powering the GPS module is 5vDC and it is continually on, regardless of whether tracking has or has not been obtained. In other words, th...

    Please see the chat and amplifier that you quoted on. The understanding is that you complete the rask for a fixed price although you asked that a hour rate project is to be made. We both agree that when the design is done that the fee of 450 is to be paid for the task, irrespective of the time spent to complete the task. My engineer will review the schematics and consult if he sees any possible problem on the design. Then you can complete the pcb. Please take care of the component that is to ne used as not to become obsolete.
