    I would like to design a rotary spindle that can take loads up to 50kg, mounted on bearings and rotate them in a composites oven. Think BBQ bbq rotisserie. It needs to be able to have variable speed from approx 10rpm to 60rpm. It would have a simple LCD with menu to start stop pause, change direction and set RPM. It will use GT2 closed loop belt and 3d printed gears on the driven and driven gears. I am seeking someone to recommend the control board, motors, motor controllers, lcd and complete the software. Arduino with steppers motor and external stepper motor controller comes to mind, but am open to suggestions.

    Needed: We're looking for someone to join our small team who is proficient in coding in Python, MicroPython, C++ or a similar micro-controller language in order to integrate an ESP32 or similar board with other hardware. Our need is to enable communication between commercial off-the-shelf hardware, firmware and software and then use Blynk, or a similar platform, to develop the machine-human interface. This is a drone (UAV, unmanned aerial vehicle) related project so a good familiarity with basic mechanics and dynamics is necessary. ArduPilot familiarity would also be advantageous, but not necessary. Multiple environmental and situational sensors will need to be integrated, so logical programming will need to be written to include these sensors and flight actuators (servo or stepp...

When we use Raspberry Pi board alone to connect all the Sensors ● We are connecting ADS1115 ADC Converter, LCD Display(I2C) and Gyroscope parallelly on the i2c Communication pins present on the raspberry pi board, Since LCD Display works on Lower Level Voltages so we have to convert that ...

    We have a small Arduino sketch which reads the ADC on 4 pins and outputs the data to the serial port. We are using Arduino Core for STM32 but the analogRead function of Arduino is very slow. We need the ADC to run much faster and we've seen it's possible to implement this using DMA or other options. For an experienced programmer should be a quick and easy task.

I have timeseries data comming from 3d accelerometer and this data is tagged with timestamp and GPS tag. However some time GPS information is erronious due to environmental reasons i.e. going into tunnel or alot of buildings nearby and so on. Thus, I need help with implementing Kalman FIlter which can accurately estimate the missing GPS information. I can share the raw data directly via email. Technical Details of project: 1) Input to the kalman filter : X, Y & Z accelerations, Time stamp, vehicle speed (sometime missing), GPS information of the travel route. 2) Output of kalman filter: Corrected GPS position of missing GPS tags 3) Added Requirements: 3a) Should introduce parallel compu...

    I've (mostly) designed and (mostly) built a data acquisition system for a small race car that I own and race. The system records wheel position, tire temperatures, and lap times via various sensors and transmits them via an nrfl2401 module to my laptop. I can monitor all of the data via a generic user interface that I've found on the internet. I've built all of the hardware and it works satisfactorily, and all of the Arduino microcontroller software works satisfactorily up to the point I try and transmit it to my laptop. I need an engineer to review my code and make it work. In addition, I'd like to customize the GUI that I've found to my specific purpose. I'd like to have an engineer do this as it's way over my amateur head.
