Are you an engineer or academic who's very familiar with EMC (electromagnetic compatibility) design and testing? Have you solved many EMC issues and come to learn the hard way about what works and what doesn't? I'm also looking for support staff who are competent electronic design engineers, skilled in researching application notes and textbooks. Support staff will help the EMC experts to gather and collate information into a concise resource. I'm recruiting a global team to help to create a course on design for EMI compliance and if you're an EMC 'expert' then I want to hear from you! Even if you haven't created any training course/seminar material before, I still want to hear from you. Creating content will involve collating and summarizing subjects from a combination of textbooks, app notes and your own experience. I've mapped out the modules and need help creating the content for each module. You'll be matched up with the modules that suit your experience the best....

We are developing a device for use in controlling functionality of pool filtrations systems through WiFi connectivity. The device will need to perform the following functions: Broadcast WiFi in order to initially configure the device. Store simple configurations based on specific user customizations (Zip Code and Pool Size) Connect to internet via WiFi to obtain data from a external database. Utilize the external data to operate the functionality of the pool pump. (control on/off timing) We currently have a fully operational unit that is built on an Arduino Yun platform. We are looking to develop a sustainable hardware unit that can be used in mass production.

I am looking for an expert engineer to help me build a prototype as follows, location doesn't matter: - Assembling a device that pumps heat through a cable and spread this heat across a large surface area (rooftop) - Control (increase/decrease) the heat as needed - Has to successfully operate from only one outlet This has the potential to be a long term project. Please send your interest along with any similar prototypes you have built before. Thanks.

The successful applicant will be responsible for a complete 'peer' design review of an existing application. This will involve the review of all components selected, how they are integrated into the design and how the interact with each other. The individual selected for this task will be proficient in the designing of E&I control circuits and be able to produce a report on the current design and any areas that may cause an issue. Experience of burner control systems would be ideal but is not essential. Applicants must speak/read/write english fluently and be able to provide examples of similar types of work completed.

You will manually input CAD data (graphics) from existing datasheets into another format. Skills: - You need good attention to detail to make sure that the data is correctly input. - Having basic familiarity with graphics would be helpful (e.g. AutoCAD), but isn't required. - Having experience in electrical design would be helpful, but isn't required. We'll provide training and instruction to help you. This job is on-going. We get requests to input the CAD data, and we have a small team who work to fulfill the requests. This is a good opportunity if you have some time every week to help fulfill the requests.

We are looking for an experienced engineer to join us on a full- or part- time basis to look after the hardware development side of our business. The initial role is to take a hardware product, for which we have designs, and organise the 3D printing of these (including getting the designs ready for that, or at least organising that part) and to make the right choices for other hardware decisions. This will include responsibility for helping to find and source the different hardware parts of our product, ideally from 'off the shelf' elements, for example tracks and an arm/hand assembly. This is for a non-AI powered robot, so in essence the shell that our software powers. We are looking for a real 'can do' attitude from someone who wants to see a product they help create get in the hands or many thousands of people.

We modified installed and commissioned a PLC Control cabinet in a system. I have a redlined drawing of this cabinet. I need a new drawing created for the revised cabinet. I do not have the original DWG drawing that was created. I have requested that from the supplier so may get it. I need an electric schematic drawing and wiring termination schedule done for the same project. I have a VISIO and PDF of the electrical and control terminations between three control cabinets, motors and field instruments. This needs to be converted into electrical schematic drawings and termination schedules. MS Visio is required to zoom into wiring connections. Not enough detail in PDF.

Circuit design and prototype of novel energy charging system for mobile devices While the last few years have brought unprecedented increases in mobile device performance, such change has also reduced real battery life. Over the past year the mobile energy crisis has spread to over a billion new smartphones. We’re a Silicon Valley startup approaching this problem with a unique and revolutionary energy harvesting solution we believe could permanently change how mobile devices are charged. What we need- Circuit design and prototype of novel energy charging system for mobile devices. This is the initial product of several (we have four filed patents). For this first product: 1) Final product definition to understand the tradeoffs of functionality, performance, development cost and time. 2) Circuit design and component definitions. 3) Breadboard, debug. 4) Circuit board, component procurement and initial operational prototype build of 5-10 units. 5) For best integration, discussions...
