    I require a feasibility report to explore the development of a small conveyor belt system. The conveyor belt will be approx. 320mmx60mm. I wish to know my options in terms of cost - the conveyor belt, motor, electronic interface (is part of a system that will include the switching on/off of pressurised water and the on/off of pressurised air) and the most robust, yet cost-efficient way to construct the conveyor.The conveyor in mind will be constructed utilising 3 rollers. 1 roller will be positioned approx. midpoint dividing the conveyor into 2 sections, however while the 1st section of the conveyor runs horizontally, the second half drops downwards at an angle of approx. 45degrees.I also require the conveyor to be able to withstand a regular drenching of water, though the motor will be placed in airtight housing.

    Project OverviewThe Fermenter Temperature Control System is a software program designed to communicate to up to 31 off-the-shelf temperature controllers (actual controller is TBD) . The temperature controller maintains the temperature of the vessel by opening and closing cooling valves. These controllers communicate on a RS485 Modbus protocol. The control software communicates as a master on the Modbus network (via a RS485-to-USB adapter), and has the following tasks:-Transmit setpoints to each of the controllers-Display actual temperatures to the userPhase I of the project is to setup the serial modbus communications to each of the controllers, and develop a user interface to allow the end user to change the temperature setpoints and view the current temperature of each vessel. Overview (Main) ScreenThe main screen should act as an overview screen. All controllers that are actively configured should display the current temperature and setpoint. By clicking on the controller, a numeric popup screen should display allowing the user to click numbers to enter the desired temp setpoint (keyboard entry is optional for the user). There should be some alert to the user when a node that is actively being monitored has lost communication.InitializationThe user shall be able to setup the system via a .TXT or .INI file that will be read upon the start of the program. This will configure the comm ports, baud rate, etc, of the system for each of the 31 modbus controllers. If a controller is not being used, then it will be disabled in this file. There should also be a description for the vessel that will be visible from the UI.Future system expansionMany features will be added in future phases. Some of these enhancements include:-Trending of individual temperatures-Data capture of a trend to a .CSV file for import into excel-Integration of Temperature profiles that the controller will be commanded to follow-Text message alarms when the system goes beyond limits-Mobile accessibility (Ipad / Android Tablets)System Requirements-The system will run on Windows 7 professional (32 or 64 bit). -System will be programmed using the latest version of Python-MinimalModbus ( will be used for the Modbus communication protocol implementationPhase I Deliverables-A working program-Full source code with documentationExpectations of the Supplier-Provide weekly milestone updates-Prompt response to email (

It should be possible to control up to 2 stepper motors with input data entered with pushbuttons, from an incremental encoder or via the uart from a PC. A simple PC application (C#) is required to test the functionality. The stepper motors are equipped with a controller that requires a positive edge for every step and an I/O to set the turn direction. The motors are monitored with incremental encoders. The device has 3 modes which determine the form of control. Detailed specification is provided on request.Please only offer if you have experience with programming ARM Microcontrollers, task based systems, communication protocols. Basical skills in electrical engineering and motor control are beneficial. Please send links to the projects you have worked on that fit the profile.
