    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.

We need to develop a software solution, to offer a complete package to our customers.Software must be able to do the following:Read RFID card (from a connected rfid reader (usb or similar connection). When rfid card is read, check it against a database (preferably local mysql)Control a USB driven controller board that sends 12 volt impulses to the hardware we supplySoftware must idealy be written for windows operative systemSoftware must be able through a hardware interface to "read" when an event is happening (door open/door closed) and save thisSoftware must be able to accept manual commands, to use the USB controller board to send the 12 volt impulseDeveloper must be able to recommend hardware to use for the project. Everything needs to be scalable, to accept up to 200 "impulses" per PC, but spread over several USB controllers off course.

    Dear workerI need someone who can deliver me a frequency generator, called F14 as electronic solution.I need a electronical engineer which is able to deliver me a circuit board (Eagle format) with electronic on it. Virtual only.I have an audio synthisizer (wave generator from computer) and can create all wave signals from 100Hz to 10KHz. That is the input which drives your electronic.Your electronic receives the audio signal and interpret the wave form as binary values (250Hz = zero, 2500Hz = one). By interpreting these values as Bit, we can program your device, called F14 frequency generator.The F14 frequency generator will output a wave form signal as rectangle from 10Hz until 3Mhz with an peak to peak amplitude to 28V.The device will be driven by 5V only. DC converter is needed.The endprice for this product, case included should be below $30.- for production. Each item should cost me < $30.- for electronic and board and case. Quantity of 100. See the attachment.If you want to bid for this project, please write your microprocessor you want to use and please repeat in your words the project shortly.

    I have a program running on arduino or ebed platform with a text based interface to a PC through a serial port and terminal application on PC. Program is pretty simple with a few menu option and simple execution of code. Interface is bidirectional, user provides info, and info is provided to used by arduino. I am looking to make the interface to this program to a touch based graphical interface. I would like to have an app written for android tablet that will do very basic graphic conversion of this program. Tablet would talk to arduino through either USB port (can be bluetooth as well, but not necessary). Program consists of a few buttons: calibrate system, run system, enter height, enter weight, etc. Each button has a very simple routine that is executed (state diagram is very simple). Would like to add a nice background and company logo etc. Key to project is being able to do simple Android app with graphics that can communicate bidirectionally with arduino or mbed platform. Everything is linear and no critical timing events needed.

    We need to quickly draw a PCB within the area supplied. We are providing you with a schematic and a draft of PCB for you to draw.Interactions will be: show component placement to confirm with manufacturing, draw all electrical connections and then document with the source files all the work done including the gerbers for production.We are used to work with Altium Designer and we prefer to stay with it. If you work with other soft, you should be able to export it for us. The circuit is an arduino-compatible device but has other connectors. We are usign PCI-e but there are no high speed data lines.

    This small project requires very basic wireless control function of a small rc servo. The project requires a single button transmitter with battery power supply to communicate with a base station that controls the RC servo. Range of the transmitter will be 10M. Basically it is a repackaging of an rc car control system on a single servo. This project needs to have consideration for production. Will need a working prototype built as part of this project. Transmitter: Compact battery powered control of base station. Single button on transmitter to control servo. Button needs to be able to control the servo like a throttle. Wake up transmitter when button pushed. Sleep timer 2 min after activationWireless communications cannot interfere with 457 kHz systems. Transmitter pairing to base station needs to be simple. Transmitter may need to be replaced so simple paring in critical. 10Meter wireless range. Ideally transmitter should not require battery charging or replacement for 2 years. Base station:Toggle switch to power up base station from 12V power supply. Beeping signal to indicate system powered up. 10 sec intervalReceives signal from transmitter to control RC servo Approx 30 Degrees of position used on servo. 10 meter communication with transmitter. When communication fails system should detect loss of transmitter and power off the base station until the system power has been cycled on/off Via toggle switchServo fail close to original start positionBase station should have ability to adjust the trim on the servo. Compact size is desired, will need considerations for vibration and the elements. Ideally product would have temp rating to - 30 Degrees. Thanks
