    Hello, I own a Panasonic digital video camera with the following features: - It can stream the video it shoots in real time through wifi; the packets are encoded as movie jpeg. - It can record the video it shoots on a SD card as h264 encoded file; it uses hardware (an onboard circuit) for the encoding. My requirement is: to have the firmware tweaked so that the video streamed by wifi is encoded as h264 instead of mjpeg, using the onboard circuit (not by adding external libraries to encode as software). If you know how to to it, I'll be waiting for your bid. ##### Deliverables: ##### The updated firmware as file which can update the current firmware.

    Sd card CID modification 6 days left

    I am looking for a freelancer to help me with my project. I want to have possibility to change CID from an SD card. The goal of the project is the application that can change the CID no of a given SD card. It can be a Linux app, windows console app or combination of hardware (build an micro that changes pcb) and software - it does not matter. The project will be closed then I will see that program changes a CID no of a card that I will send to the developer.

    ESP8266 - TFT LCD - SD CARD 6 days left

    //This is an extremely small project. PRICE OF THE PROJECT WOULD BE 15 SGD and it would be really, really awesome if you can complete within a day! If you are that good, I will consider slotting you in for my main project as this is a side one :) What you need: //Hardware: 1. You should have a 2.4 inch mcufriend tft lcd [url removed, login to view] 2. SD card (and maybe SD card shield?) 3. ESP8266-01 4. GET and POST codes for ESP8266-01 (Nah, I will send you mine! Use mine, and you can use it for future applications. I believe I have one of the shortest get and post codes around) //Software: 1. You need to have a SQL or any other working database. I will give you the columns and you can create one in anyhow and anyway you want on your side. 2. A web API, or anything which is acting as a middleman between the esp8266-01 and database. So long as the final GET request can and must output in json notation. //Okay, now we have come to the caveat. Project description: 1. Perform a GET request so that only the last row of table is extracted. (This step should be easy for you). 2. Depending on the values of the data, it has to be translated to different instructions on the tft lcd screen. (Only a small part of the screen is required :) ) 3. The instructions has to be there even after power cycle of the tft lcd, and will be dumped when a user executes the instruction by pressing on the screen. Hence, I am assuming it has to be stored somewhere.. maybe a sd card in the tft lcd? //Conclusion. That's it! If I have additional things to add, I will add in milestones for this project. I am very clear with what I need and require from you. Lastly, I hope this can be done in 1-2 days.

    I need an ultrasonic sensor with Bluetooth capabilities that can connect to an Android device. The premise is I would like a blind spot detection that alerts my phone when someone is in my blind spot. I'd prefer to use a 16mm Ultrasonic Sensor, something small that is easy to place in my car. Also if possible I'd prefer it in a custom app rather than the standard Arduino android apps. But I am open to alternative options. I'd prefer the sensors mentioned prior but if Arduino or raspberry pi is only options I am open to it. Can this work be done? How long, and cost?

    ***PROJECT SUMMARY*** I have created a detailed functional specification which I want you to help me transform into a circuit design. This is *not* a PCB layout project. This is a circuit design project. Although the circuit will likely use an ESP8266, I do not require that you have any experience with the ESP8266. Instead, I am looking for engineers who have experience with micro-controllers such as PIC, STM, AVR, FREESCALE, NXP or Zilog or similar. ***COUNTRY OF RESIDENCY*** You must currently live in: - Pakistan ***YOU CAN AVOID “SPENDING” ONE OF YOUR [url removed, login to view] BIDS *** Of course you can apply for this job the “normal way.” However, to avoid “spending” one of your [url removed, login to view] bids you can “apply passively.” I realize that [url removed, login to view] gives you a limited number of of bids every month depending on your membership.

    I need a some one to give me a solution so I can encode and decode using an MCU (Arduino or any other MCU) a FSK code a based on BELL 202 Modem standard, 1200 baud, half duplex. The solution may be a code or an hardware (frequency filters) and a code for MCU. If it is possible I prefer the solution with C code where only a pin and interrupts on that pin are used without any external hardware frequency filters. I already have an operational amplifier for convert from a low voltage to 0/1 digital. This it is the description of the code I need to decode/encode: "The time code is actually an off BELL 202 Modem standard, 1200 baud, half duplex, FSK modem signal. Half duplex means that signal is only in one direction and FSK, or frequency shift keying is the type of modulation. This standard was developed, and is suitable for transmission over normal voice grade phone lines, however if transmitting over phone lines precautions must be taken to insure the integrity and quality of the phone line. A dedicated normal voice grade line, with a backup, is recommended at minimum. Full testing of the line using verifying procedures several times is absolutely required. The time code itself consists of a distinct and unique number every 1/10 of a second. The time code is generated in a sequentially increasing manner, starting from zero to a maximum of 32,768 tenths of a second (16 to the 4th power divided by 2), in 1/10 second increments. Each time code number starts with an S followed by 6 hex characters, the first 4 of which are the time code number and the last two characters is a truncated check sum. The zero time code is thus S000000, the next is S000101, 33 tenths is S002121. A hex to decimal conversion of the first four hex numbers will give the time in base ten tenths."
