I need developed complete electronics (populated PCB) as described here:   [obscured]  /controller/ Long term production will be required and I will need a cost per unit/ in volume of 5-10 units but production is NOT a part of this platform. Just the development which includes the design and working test unit. I'll need all paperwork associated with the design. Each time we re-designed we improved the end product substantially. That is why I am making this query. This will be our last improvement (I said that before) so it needs to be done correctly. Note: I have several versions in the worldwide market since 2008 so I know EXACTLY what my costs are. Any/all bullshit will be ignored. I wasn't born last night. Note: This is high school 101 electronics, very simple, uncomplicated. Note: I do NOT want to hear about your qualifications, your team, blah, blah, blah. Either you contact me to get to work or leave me alone! Note: If you have responded previously, you...

I need to make a prototype of an earpiece-like device that can receive transmission of soundwaves from underwater. I am thinking of using bluetooth, but I am not sure if it works underwater. I was also thinking of using radio transmission, but I would like you expertise on which option, or if there are any other options, would be best. .

Atmel IDE Design Platform ARM Cortex Processor Processor: ATSAMD20J18A This is a two part device where the devices control and communicate with each other over a bluetooth interface. Person should be familiar with: Embedded microcontroller coding, C, C++ Embedded System Development Basic Understanding of Electronics (No hardware design required.) Atmel Studio IDE Atmel ASF Controlling a Bluetooth Interface (HC-05) by a UART port with AT commands. Controlling remote devices on PCB through an I2C interface. Some capability speaking and writing English to document and comment code. Comment: Do not need HW design skills. That is nice to have but not necessary. I am an EE with a lot of design experience. PCB's have been finalized and are now in board layout, so the intention here is to get started on the code while the boards are getting laid out and fabricated. More details on the project will be given to people so a better time and cost estimate can be made. Prototype versions...

We want to build a passive radar system. To keep it short we basically want to improve on this SDR based Passive radar(  [obscured]  -sdr.com/rtl-sdr-based-passive-multistatic-radar-used-track-aircraft/). Requirements: 2)Detect at least 10 planes at the same time 3)Assign Ids to all detected plane (  [obscured]  /watch?v=LNaL58GRou4) Something like this but for the planes. 4)Track the plane selected by the operator 5)The software needs to calculate the GPS location of the plane + altitude + Speed + Distance of the plane from the camera + expected path 6)The system will need to identify the planes by make and name 7)Have a traditional radar GUI + Show the plane( that is being tracked) on Google Maps Further details will be discussed on contact.

I am looking for someone to produce code for a microcontroller which is to act as a node in a wireless mesh network. The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

I am looking fro someone to design and program an HMI for a wireless mesh network node. The node will have a 2.4" touch screen with an SPI interface. The user will be able to select either one of two fixed channels (Channel 1 and Channel 2) or a third 'Home' Channel which would be selected by the user from a list of available channels. The menu structure is envisiged to be something like as follows: Page 1: Button to Select either Channel 1, 2 or Home Channel. Page 2 (or popup): Ability to set a channel as the home channel or select a fourth channel for listening. Menu structure as: Menu Level 1 (Nine options) - Menu Level 2 (Max 50 options) - Menu Level 3 (Max 20 options) The names for each Menu level or Channel would need to be editable and updatable by a remote connection so this needs to be borne in mind when programming. The graphics do not need to be fancy and a simple, clean, user-friendly interface is preferred. The processor would need to be an Arm Corte...

Parametric analysis of Solidworks flow simulation are to be carried-out using flow simulation API, the main idea is to edit already generated codes in VB 6.0 into VB.net or C++ (prefeably C++) , a plugin in terms of fluid codes (using codes already generated in C++ for navier-stokes momentum equation) should be embedded into the solidworks flow simulation environment), the VB 6 codes are able to do the following: 1. Change different impeller types used for the study 2. vary fluid height in the mixing vessel 3. Varying impeller rotational speed 4. Vary impeller distance from the bottom of the mixing vessel The plugin codes are written in C++, and its untended to be introduced into the mixing vessel as an external fluid and different results ar intended to be generated from the simulation that would determine which impeller gives better homogeneity and at what impeller distance this should be achieved.
