    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.

    I have 2 cameras recording traffic in a parking building with 2 entrances/exits - 1 camera on each entrance/exit. Both cameras are connected to a PC running Windows 7 and ispy software ( I need someone to setup the license plate plugin that is available for ispy ( and write additional software that will do the following:1. Recognize the license plates of cars entering and exiting the building2. Write a new line in an excel file for every car that enters or exits, along with its license plate number3. If license plate is not recognizable, then record the image of the license plate in a folder and reference the filename in the excel file4. Create a new tab in the excel file every day, and a new excel file every month5. Setup Ispy in such a way that it only records cars passing by and not people (motion detection detector types and trigger ranges)Remarks:* Both cameras are Foscam 9826w connected via 100mbit ethernet cables. * Lighting is fairly good. * Anyone seriously interested in undertaking the project will surely have to do some evaluation before accepting the job, so Teamviewer access is available on request. * The cameras and the PC are online 24/7 on a dedicated VDSL (50mbit d/l, 10mbit u/l)

    We are developing an audio remote control for car/boat stereos that is unique to the industry. We will share more details upon hire. What you need to know: We have learned that we need a particular Bluetooth chip that meets the requirements of range (approx. 100 feet) and battery life (ideal goal is to have disposable common battery that lasts 3+ months, rechargeable if we must). Also, this chip is unique in that it can connect to both a smartphone or directly to the stereo receiver (AVRCP mode). This is important to have both options because some consumers don"t have a smartphone and wish to link directly with the stereo. I am in need of someone to program the chip. The chip is the WT32i by Bluegiga; I have this development kit for it tasks are to program the chip so that it can link up with the stereo receivers (AVRCP mode) and control the basic audio commands of Play, Pause, Skip forward, Skip backward, Volume up, Volume down. Additionally, I would like a button that will scroll through the various Playlists, if any. This Playlist function would be used when an MP3 player such as an ipod/iphone was the source of music play (since these devices use Playlists), whether connected via smartphone or via stereo receiver. Another button would be an Activation button that would need to be held down to activate the other buttons. This prevents the buttons from being inadvertently pressed or pressed by the force against the water when the rider falls and lets go of the handle. The same tasks are required for linking up the chip with a smartphone. Preferably, it would link with the native audio player on ios, android, and windows smartphones. Alternatively, we would create a simple media player app top connect with. Also, thinking about whether it would work with apps such as Pandora (it would likely work if connected via stereo receiver, but would it work if connected via smartphone?). Finally, in both scenarios, we need a switch or combination of button pressing to determine connection route (i.e. hold down play button and skip forward button for 5 seconds to connect via stereo receiver, …and skip backward button to connect via smartphone). We have a PCB board developed, but will hold off on ordering it until the chip is programmed since we may find some things to tweak in the process. For example, I think we need to tweak it to have a switch or combination of button pressing to determine connection route (i.e. hold down play button and skip forward button for 5 seconds to connect via stereo receiver, …and skip backward button to connect via smartphone). Pardon my ignorance, but I don’t know whether this is implemented into the PCB board, the chip, or both. We also need to look at the current battery set up and see if it suits classic Bluetooth well for power consumption or if we need to switch batteries or go with rechargeable.Rechargeable might not be so bad if we must since we should implement a mini USB for updating the device anyway. You would need to program the bluetooth chip and/or PCB board to implement mini USB. THE DEADLINE IS 4/22/14. This gives us 6 days to get the PCB board ordered and delivered and 6 days to put it all together for the design show on 5/6/14. Even if our deadline cannot be met by a given referral, I am still interested in the referral. Perhaps I can make some adjustments to the schedule and still make it work. At a minimum, we could get the AVRCP mode accomplished first by and then the smartphone mode second. Thank you for taking the time to read this and possibly refer me to someone who could handle this project (or hopefully you can do it!).
