We have a sensor integration design in Eagle which was based on this reference design: https://developer.mbed.org/cookbook/Reference-Design This job is to check, validate, and help lay out the production PCB board for this project, to translate the reference design to a DVT PCB. A follow-on project would be to revise the design for integration into a full-series production board, i.e. there are further opportunities here.

My team has been working on a prototype for a device that sits on a DSLR or mirrorless camera, connects to the camera via usb and allows the user to control the camera over wifi or bluetooth. We've been using the Intel Edison. We would like to get a custom pcb designed that connects to the edison through the 70pin connector and provides the following: 1) usb 2.0 micro OTG port 2) LiPo charging circut, powered via a 2nd 5v usb micro plug 3) boost circuit to give 5v to the usb OTG port 4) on/off switch accessable from the side of the board (surface mount) 5) power led which can be disabled by a pulled high gpio pin (surface mount) 6) another led connected to a gpio pin (also surface mount) Most of what we need is already available in the following sparkfun boards: https://www.sparkfun.com/products/13045 https://www.sparkfun.com/products/13037 Both of the boards above have eagle files available as a starting point. Just to clarify a few things: 1) the board must power the edison from the battery, 2nd usb power port, and seamlessly transition between the two without loss of power to the edison or usb. 2) the board must charge the lipo battery when power is available from the 2nd usb power port. 3) the board must charge at 500mah when available from the usb connection (I understand there's some ways to request even more power from usb to make it charge even faster, we will most likely have a 1C 1000mah battery, so faster charging is a plus if possible) 3) the board must provide 5v to the OTG usb connection (otherwise some camera's won't connect) 4) the board must have a led that lights up when the power switch is enabled unless a specified gpio pin is pulled high. (So normally the light would light up, but we could disable it from the software while running if needed) The sparkfun boards should be a good starting point, they also have a template for intel edison "block" you could look at (https://www.sparkfun.com/news/1591) Though you might be better off looking at the base block as a starting point. Lastly, included as part of this project would be helping me through the process of getting the prototypes and board manfactured. For the prototype version, we expect to only need about 20to 50 of the boards. Later versions may require a larger number of boards, but helping with that can be considered part of a seperate job. One thing to keep in mind is that edison's 70pin connector is kind of a weird part and I'm not sure all manufacturing houses can handle it. One last feature, while not a requirement, would be a "nice to have" option. (So let me know if its something you can do) Some camera's can charge or be powered through the usb port. Ideally it would be nice to be able to plug the board into another usb power source (portable usb power bank for example), and charge/run the camera at the same time. Pleaes hit me up with any questions or things I need to clarify. Thanks, Ryan

Like to design control board to power a split AC unit fan with out all the crazy items that we need to adapt to use these new inverter power fans. Right now we are gutting the compressor to get control panel / inverter and do not need this once designed. Fan is 36V with 5V control signal, variable speed.... We would also like to be able to over ride the limits of the cooling from 64 to 58 degrees in these units on a seperate board, some companies have done this, but the application of how it work is very bulky and not high end clean look. So if you think you can help lets link up.

This projects involve designing a single circuit board assembly for various components. I currently use an arduino, HX711 amplfier and wifi module as 3 separate units as a prototype. The unit will accept an input signal from 4 array strain gauge assembly, exactly like a bathroom digital scale. It will use 4 purchased 3-wire strain gauge load sensors . The circuit should amplify the signal, clean and process the signal using a low-cost microprocessor (i.e. Arduino Teensy, or alternative) and then send the signal via a wifi module also incorporated onto the board . Combine these into one circuit board: - Strain gauge signal amplifier (example: HX711 Load Cell Amplifier) - Microprocessor unit (example: Arduino Teensy or low-cost alternative) - Temperature sensor - IoT low cost wifi module - Run's off battery or an AC adapter that plugs into the wall. The design does not have to use the same components I prototyped with. I am looking for a low cost mass production model that achieves the same purpose. If you have done a similar project with  lower cost components, that is desirable. Expected Deliverable: A circuit design on a single board that achieves the purpose above with a low-cost component BOM. No physical prototype is necessary.

Hello applicants, Our Product is almost complete. My engineer left due to illness toward the last leg of the project. Now I need someone that can pick up where my engineer left off. I have the gerber files and all the info that i will share with the applicant. Scope of the work: Battery Controller : New Design, Scope includes Schematics design, PCB design and Gerber package generation. DC to Ac Inverter Board : Design review and change. Package Generation. Inverter do not support grid charging and do not support Online/offline interactive functions with Grid. The output cannot be connected to the grid in any way and loads needs to be seperate wiring. It is possible to design line interactive Inverters or grid charging type. Control Unit : Schematics changes, PCB design. Programming/software development. Other boards such as Inverter, DC-DC push pull converter need signals from this board. As all control functions implemented in software for all boards are from MCU located in this board. DC-DC Push pull converter : Review of design, design changes, package generation. . AC-DC converter from Grid : New design to be made. Enough power to support charging of battery. Solar DC-DC regulator : For DC bus, 100W panel.
