    I would like a board with 16 inputs (or an option for 32 inputs). I would like to be able to configure the inputs to accept 1. PT100 temperature probe 2. J Type thermocouple 3. K Type thermocouple 4. Thermistor temperature probe 10k at 25C 5. 0..10v I would like a muliplexer chip so that I can then select an input for the boards output. I would like to be able to configure the voltage of the output to be 0 to 5v or 0 to 3.3v. Power supply to be 24vdc With regards to the 0 to 10v input. The source can be a frequency drive and can therefore create noise interference. Therefore would it be practical that these inputs are on a seperature board or isolated in someway so that the noise does not transfer to the board. Currently this board will be connected to an Arduino Mega. Experience from our own proto type is that communicating the output with a voltage is also susceptible to noise. Therefore would it be better to communicate using a bus method such as SPI, If your proposal can consider this then we would also require C# code to assist for integration into our proto type system. Input/Output terminal, channel select and power to be screw terminals.

    Our team needs to collect data for machine learning. We need a battery powered portable device capable of logging data from sensors to a microSD memory card, controlling two small motors, and enumerating as a USB thumb drive displaying log files when connected to PC.We need schematic design, BoM selection, board layout, and software development. The device will include gyroscope and accelerometer data, as well as audio recording. The device has two outputs, controlling low wattage (3-5W) motors. If your team can provide a complete schematic in EAGLE, we can do the board layout.A detailed statement of work (Word document) is available for interested candidates. We are looking to start immediately, but are budget-conscious (our company is un-funded, so as much as we want to pay you a lot, we can"t).

    Development/Coding of the software for a control system that uses stepper motors. Task based implementation with state machines and non-blocking tasks is required. Flowcharts, State diagrams, microcontroller pinout and codesamples are provided.Periphery:•2 Stepper motors (already with stepper controller)•2 incremental encoders•5 Indicator LEDs•2 End switches•6 push buttons•2 Mode Switches•1 Uart interface•1 Alphanumeric DisplayuC resources: UART, Capture-Compare Timer, PWM Timers, Incremental Encoder Timer, DMA and I/Os Environment: Keil uVison or IAR Workbench (preferred)Requirements:Code should run on STM32VLDISCOVERY Code should be written in C++Input and output signals need to be testedTimings needs to be verified with logic analyser or oscilloscope (Test protocol needed)Source Code provided (Keil or IAR Project)2.Description of operationThe device is intended as a control unit. 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.

    Seeking an embedded systems engineer (or small team) to create a Schematic, PCB layout, and Firmware for a Bluetooth LE enabled motor controller inside of 12 weeks.Each controller will command a stepper motor in a closed loop fashion with encoder feedback. Experience with Bluetooth LE, closed loop control systems, and good knowledge of DC power is desired. Each controller is powered by 9 - 24vdc and will need an integrated boost regulator to provide 48vdc to the stepper driver. The PCB is of a custom shape with specific limitations on component height and placement in certain areas of the board. The specific IC components of the controller have largely already been chosen. A Solidworks model of the housing and PCB shape will be provided to assist in the design.Multiple controllers will work together in small groups and will receive commands in one of two ways: 1) A smartphone/tablet maintains an active BTLE connection with multiple controllers and sends specific commands to each one.2) A single controller receives commands via a USB port and relays the commands to other controllers on the network.We are looking to hire from within California but will consider applicants from the western U.S.A. We"re sorry, but no applicants from other countries will be considered for this project.Please send resumes with references and applicable experience. We will supply full details of the product to interested applicants so you can quote accurately. Thank you.

    Hello I was reading your reviews and it seems you"re a very capable electrical engineer.I was wondering if you would be able to create a pair of rechargeable battery poweredLCD glasses that would be transparent normally but when powered completely black and unable to be seen through.The main feature I"d wish of these glasses is a few automatic timer settings. For instance one being that the glasses would be black for 2 seconds then clear for 2 seconds on a loop.Please let me know if you"d be able to work on this and what the price would most likely be.
