    newmodel [ Incomplete Report ]

    Aug 25, 2012

    Xtint Technologies (the worker) agreed/admitted that they did not complete the project-- they used 3rd party code without the employer's permission. All funds in escrow were returned to newmodel (the employer).

    xtintt's reply:

    Never obliging on use of 3rd party code.Failed to provide hardware resource to do his job.Not paid even single $1 to us..Never work under this employer "newmodel"

    I need a software developed what would allow me to control the permissions on a USB Thumb Drive. An example of what is needed is that i want to put music on thumb drive but have it read only. User is able to play songs via computer or car stereo but not able to delete or edit or overwrite. Password lock on USB...if too many attempts are made...USB will be wiped of all information.

    simulation of 8 bit microcontroller using verilog

  • $555 CAD Jan 17, 2014

    The PIC32MX150F128D communicates with a 8051 Microcontroller via UART port. This is implemented and working already. What is needed is a function that will allow PIC to write new firmware onto the 8051 using only Rx and Tx lines. Firmware will be saved on external Flash accessible through SPI.

    I need an a device which can help me switch ON/OFF my circuit by sending an sms. The purpose is to control the input and output of a PIC 12F675 IC. I need to get an application (or any other way for the same). It should be capable of switching ON the current to PIC 12F675 to activate the circuit and then with the next sms/call, should be able to stop it.(Please note that the voltage supplied to PIC12F675 will be 5V,and anything if added, as hardware should work on same voltage. Also, since the same would be present inside a shell it should have parameters close to length-44 mm, breadth-12mm and width-5mm). In case you need to better understand, the circuit should take place of an RFID remote control and receiver circuit, as we need to replace the same, with chic mobiles, which can do the job using sms technology. For further discussions, you can get in touch on skype. ID- sundeep_ballare. Cost of project should not exceed $100 and should be delivered in 3-4 days.

    i have a schematics for PIC32MX460F512L in which a camera is attached at one port and a wifi device is attached on the other port. the camera will take grey scale photos and send it to the external memory location which is also attached to a port in the schematics. after taking photos for a minute and saving them in the external memory, the microcontroller will output the data through the wifi device. i need a Proteus simulation (if PIC32 module is in Proteus) or simulation on any other software that can simulate like Proteus and a C Program code that will work on the Proteus simulation so that confirming that the code is right for the schematics and working.i need the job done in not more that 2 days.

    This project is for someone with Microchip micro controller skills. It&quot;s a redesign of something we already have but using exclusively microchip components and implementing a minimum component system.The device should use a Microchip WiFi device ( not the newly acquired roving networks component) and the Microchip TCP stack to connect to a specified router and POST data to a web server. The data is acquired via monitoring several input pins and logging their status over time. On connection to to the router the data gathered is sent via a POST command. The unit will be vehicle mounted so the device must constantly look for the router being in range whilst monitoring the inputs. On successful POST the device should sleep then and detach from the router for a pre determined time. More details will be supplied to bidders to clarify the project.

    Project Brief:Multiple-antenna techniques constitute a key technology for modern wireless communications, which trade-off superior error performance and higher data rates for increased system complexity and cost. Spatial Modulation (SM) has been recently proposed as a new modulation concept for MIMO (multiple-input, multiple-output) systems, which aims at reducing the complexity and cost of multiple-antenna schemes. The basic idea of SM is to map a block of information bit into two information carrying units; (1) S symbol that is chosen from a complex signal-constellation diagram (e.g., QPSK constellation), and (2) A unique transmit-antenna index that is chosen from the set of transmit-antenna in the antenna-array.This project will focus on building the simulation program using MATLAB to study the performance of SM under different channel fading conditions, number of transmit-antennas, and power allocation methods.Deliverables:-Programmer must be proficient in MATLAB.-Read up the Research paper – As attached “Spatial Modulation”-Programmer must deliver the following outputs:-Symbol Error Ratio: 16QAM 4 x 4 Spaital Modulation (Both Simulated and Analytical) Transmitted bits 6 bits/Hz-Symbol Error Ratio: 16QAM 4 x 3 Spaital Modulation (Both Simulated and Analytical)Transmitted bits 6 bits/Hz-Symbol Error Ratio: 32QAM 2 x 4 Spaital Modulation (Both Simulated and Analytical)Transmitted bits 6 bits/HzAll simulation must be done using MATLAB as per the research paper. For each simulation, write down the comments for each step of the simulation, to provide easy understanding.

    We need someone who can help us in web to mobile SIM communication and then mobile SIM to microcontroller communication. It should be bi-directional communication. We need to operate microcontroller from web. We need the latest technology for it. If you have any questions then ask by private messages. Thanks.

    I need a software that would decode a magetic card .wav or .bin audio files into numbers and characters and display the result in a human readable format. The required data is embeded in the audio files and need to be extracted. The files also contain lots of noise and gaps.some files maybe interrupt swipping,sw must combine data and give me real data . i know some people use some sw for clear noise and repair file before decoding witw goldwave , audacity and etc......Looking for an ALREADY WORKING software basically capable of:1) Decoding magnetic stripe binary data (5-bit, 7-bit-8bit) recorded in waveform (PCM uncompressed)2) Supporting interrupted swipe recordings, in other words, WAV recordings with gaps/silenceIf you have experience in Aiken Biphase/F2F decoding algorithms and have a working solution, sample WAV files will be provided.1) Decoding magnetic stripe binary data recorded in audio format file .2) Supporting interrupted swipe recordings, in other words, audio recordings with gaps/silenceI need a software that would decode a magetic card .wav or .bin audio files into numbers and characters and display the result in a human readable format.
