We are looking for a partner that can help us design a GPS tracking product based on a set of requirements. The contractor will likely work with us through multiple iterations of the PCB as we optimize and test different configurations. The contractor will develop the hardware and part of the backend software required to test the device. The result should be A. a custom PCB that meets the form factor and power requirements and B. a backend that allows us to make calls to the device in order to get the location data. Requirements: External device volume of 32 x 32 x 6 mm including the antenna and battery (excluding the case). The tracking device is comprised of 3 modules integrated on the same printed circuit board: GPS module, 3G module, microcontroller & power management module. The tracking device will acquire location through the GPS/GNSS module then will send it at specific time intervals. The voltage will be supplied by a flat Li-Po battery that has safe discharge circuitry built in and will be regulated by a switching regulator according to each module needs. Connectivity is provided by an mff2 M2M sim chip.

Looking for a team to develop an app and a minimal backend for our wearable Electrocardiogram (ECG) device. It will be very similar to the Garmin connect app, except the ECG will give more detailed and real time information than a simple heart rate monitor. First project scope will be to develop an Android app for phone and tablet, plus a minimal back end, but there will be future jobs for iPhone/iPad version, and the full back end and web app. All work can be in English, but must have multi language support built in, so that I can quickly translate this app into Japanese. SDK will be provided to connect and get data from the device. Must have experience with Bluetooth low energy devices. Wireframe is attached, and function requirement is available for applicants. Applicants should have some UI and UX experience, enough to critique and discuss my designs and make necessary improvements and adjustments.

Hello, I'm looking to develop a bot that can grab hundreds of tickets for multiple events simultaneously and let me choose which tickets from the list to buy with just a single click on Ticketmaster, Livenation and potentially other sites as well. The software will need to be integrated with a 3rd party CAPTCHA bypassing services which allows me to bypass the CAPTCHAs from these websites. Here are other things the software will need to have: Grabs tickets and hold for me instantly as soon as they get dropped Scheduler: To start searching for tickets at a given time. Works on Onsale as well as Pre-Sale events Grabs only particular tickets having specified section and/or row Notify me via email/sms/sound when tickets are found Option to automatically purchase tickets as soon as they are found Multiple Proxies for different threads or another way of making sure my location can not be discovered I actually have a similar program already but it is cookie cutter. I'd be willing to provide that software for you to work with as a starting guide. This software actually has a video at https://www.youtube.com/watch?v=wkf_CX4J1eQ I would want to have a phone discussion with potential freelancers, so please provide a phone number and best times to call.

need help to implement this lab by java or c, and all information and function in the attached document. ... By your program you should solve a congruence equaĕon in order to determine structure of a P2P system based on this equaĕon. Suppose we have this equaĕon: ax=>b(mod c) Inputs: a, b, c, n n: is number of nodes in each cluster. ... (Use arbitrary IP address and just care about the syntax of IP address to be 4 bytes) Outputs: 1‐ Group‐Head Table based on following characterisĕcs. a‐ Column 1: Resource Type. (R1, R2, R3, ...) b‐ Column 2: Group‐Head ID. c‐ Column 3: Logical value of each resource type (congruent answers). d‐ Column 4: Logical Address of each group head (congruent answers). e‐ Column 5: IP address of each group‐head. f‐ Number of rows = Number of clusters. 2‐ Member Table based on following characterisĕcs: a‐ Column 1: Node ID. b‐ Column 2: Logical Address (incongruent answers). c‐ Column 3: IP address. d‐ Number of rows: Number of nodes in each cluster (Given by user). e‐ Every member of each cluster should keep this table.

I purchased a piece of software last year. It has some type of web-based security on it that gives a remote company the ability to restrict access. Even though I purchased this software for life, they have blocked access to the software and will not work with me, so I'm not able to use it now. I paid to use this software for life. I'd like to find someone who can remove the security on it which would allow me to use the software again. I'd also like to make sure they can not track when and where I use the software. I would also be interested in "tweaking" the software to make it better if you are able to successfully unlock it. Upon your proposal, I can provide you with the software. I have it in a zip file.
