Looking for few Electrical engineers who have experience of working with AutoCAD Electrical design software. The design process is: 1. Client gives the design drafters an IO list, instrument list, BOM, load list and they will put together the initial single line drawing, drive schematics and IO schematics. 2. The Client engineers will then review the drawings at each level.

We have a unique device sensor type application. The device consists of one large capacitive sensor array similar to a large touch screen and a small control and interface board containing an ARM M3 controller and color TFT display which both controls the sensor array and displays the results. The engineer we seek must have good knowledge of capacitive sensing including projected self and mutual capacitive sensing techniques as well as C programming skills, experience with embedded design and pcb layout. The device is also battery operated and thus contains a small buck/boost regulator and 500mA charger. We need someone with experience with microcontrollers, battery operated designs, TFT displays, capacitance sensing, pcb layout and prototyping.

We are looking for an embedded C developer for 1-3 months *FULL TIME* embedded product development, to join our existing team. We need experience in STM32Cube as well as STM Standard Peripheral libraries on IAR platform. Please tell us if you have worked with this. The ideal candidate should be good at Embedded C programming and Microcontroller peripherals like BootLoader, I2C, UART, GSM, GPS, Iridium, Low Power, USB, WiFi, Accelerometer, SPI and also FreeRTOS as its RTOS. The candidate should also be a strong team player capable of working in a team and providing robust code that can integrate well with the rest of the product. Experience with STM32L4/F4 or ARM Cortex-M is necessary. The development environment is IAR IDE. Please specifically describe your experience with IAR and stm32 peripherals in your bid. Please apply only if you can spend 30-40 hours per week on this project with a start date of around a week from the time we select you. Also you must have quick response time and be ready for urgent troubleshooting whenever needed over skype. Prefer to interface with technical individuals and not companies. If you are part of a company, please provide your individual credentials and apply directly.

Looking for an engineer that can help design and source parts to build a very simple balanced to unbalanced audio converter PCB in a form factor that fits into a computer's PCI/PCI-E expansion slot. We need either someone who can perform the one time job of designing the device or someone who can design, manufacture, and assemble the device. Our MOQ expectation is fairly small (<100 pieces).

Hi all, I request your expertise for an interesting Hardware / Software project which could be scalable in a near future. I need 1 expert to set-up a prototype for internet connected speedometer and powermeter. It supposes to build necessary hardware with all relevent sensors to get all variables I am looking for: Watt, speed, distance, RPM. This device could be made of several parts, must be small enough to be fixed to crankset and handlebar. This device must communicated via Wifi to a server to aggregate data. There are several others requirement which could make this project interesting for you like mobile app dev. Hope to find an expert with whom I can discuss in details about this project Micro-controlled cycling speedometer / powermeter (IoT) 1. Functional requirement: Convert traditional indoor cycling fitness bikes into smart bikes to provide end-users with a new performance and sport experience. Vast majority of bikes used in these fitness classes are purely mechanical bikes missing embedded basic performance measurement and display.  It is expected to provide a cost-effective device easily configurable and mountable on indoor bikes which could measure speed, average speed (km/h), distance (km), rounds per minute (RPM), power and average power (watts).  It is expected to get a device which is user-dependent. o a QR code must be attributed to each bike. User must sign-in with a dedicated mobile application, where he could have registered beforehand all necessary information potentially needed for measurements (weight, height, age,…). o Following identification, bikes start transmitting parameters to server for performance measurement calculation. o Smartphone used for identification should display user’s performance information in live. o It’s not expected for the moment to work on UI.  It is expected to get 2 modes of use: individual and collective. o When collective mode activated (fitness class), all devices (bikes) should be connected under same independent session. All bikes are in the same room. o All data are transmitted to server for individual and collective performance display on the smartphone. o Ultimately, we would expect different display on the smartphone (individual) and collective via overhead projection (performance comparison between users, ranking,…)  Second step of development, once hardware and performance indicators are properly aggregated, stored and displayed, it must be considered that application should display historical data and historical comparisons between users of a same collective session. For your information, bike which should be used for the prototype would be like : http://www.nutri-cycles.com/documents/Image/seances-spinning-3.jpg Please let me know feasibility and a rough estimate. Of course, if we decide to work together we'll work on an iterative way. I am not expecting a final prototype just based on one conversation. We'll be able to set-up skype meeting and even be able to travel
