I need an electrical engineer to help me design a small ultrabright LED prototype product for my clothing line. I have 3D renders completed and a basic idea of what I want in the electrical platform. Although, I do need the entire interior electrical platform built for this product. I am hoping to get the prototype built and a small product run completed at least 12 working units. This is a pretty simple design and functionality. I am also looking to have this completed in the $1000-$2000 range. I look forward to hearing back from you all.

Background: I hired a freelancer to develop a simple wind turbine design that was completed in MatLab and to also develop a technical report and a PowerPoint presentation explaining his design. He completed the design, the technical report and the PowerPoint presentation, but the quality of his report and presentation were not up to my standards and did not fully explain how he designed the wind turbine. Scope of Work: I need someone to analyze and understand the design, the technical report and the PowerPoint and extensively modify the report and PowerPoint by mostly elaborating on every step taken during the design phase and how the results of the design came about. The design is basic and I can provide all proper documentation if needed. Requirements: Freelancer must be very fluent in English, capable of writing excellent technical reports, capable of analyzing and explaining designs, could complete the job in two weeks, good communicator that provides updates once every two days ...

We are developing a new kind of "Walking Desk", faster, more effective and more simple for the user. For this, we are using an arduino card and a touch screen, the SPARK CORE and the adafruit HX8357, specifically. We need someone that can manage with all our specifications of this new prototype. We need someone with both programming and creative skills. The idea is to have a code to control a treadmill with the basic functions, start, stop, +speed, -speed and some other specifications. All this, controlled by the user through out the touch screen interface. The interface is also an important thing while working in a product that is going to be used by people. It has to be creative and attractive to human eyes. Is an interesting project and there are possibilities for you to continue working with us. So if you want to know more about this, send your resumes!! We will have a quick answer for you Is important to now something about the SPARK CORE !

It is a multi-functional battery charging controller. I'm using MSP430F2274. You'll use Code Composer Studio. Perhaps you may use Grace or any other io configuration tool or libraries. You'll develop a program running on the MSP430F2274 with the feature as : 1) 3.5 digit LCD and 8 LED control with 5 74HC595 serial shift registers. 2) ADC control to read voltage and current of the charge/discharge. 3) On/off control of charger, load switch, etc. 4) Timing control using timers. Perhaps you'll control an RTC device. 5) Uart communication channel to receive command and to transmit the status value with regular interval.

I am looking for someone that is knowledgeable about the USB and Ethernet Phy so that they can help develop a product. Ideal microcontroller would be the Atmel AT32UC3C series. I suspect it should be capable of doing the job. I will work with you to do the schematic and board layout from my side. I will need you to write the code to program the AT32UC3C and send to me so I can program on my side using the Atmel Studio. Essentially the unit is to pass data between the two interfaces without data loss. Meeting an Ethernet speed of >10Mbps is strongly required. Only those that know what they are doing should apply. I am very knowledgeable in this area. I just do not have the software experience to make this part happen.

We just bought an old house. There is a dated fireplace in the living room. Now we are thinking whether we cant remove the wall and fireplace entirely. The wall is 8 feet tall and 11 feet long. The house is in Corona, CA. If you are local and can stop by to take a peek, would be great. Otherwise we also can use dimensions and pictures to discuss online. Thanks!

Hello, I need a working concept of a "pressure plate" type of object that wirelessly tells a computer whether there is something on top of it or not. I need info on how much this would cost to produce, I need the cost per unit to be as cheap as possible while still functioning. I will later need software that sends the information (whether there is something on top of the plate or not) to another application. Under an inch in height is high priority.

I have created a prototype of a web-connected bulb using a Raspberry Pi micro-controller which connects to WiFi, a PowerSSR Tail that is controlled by the GPIO of the Raspberry Pi (  [obscured]  /pages/powerssrtail.aspx), and a standard light fixture. I would now like to move my design forward, in order to produce several dozen units. I would like to miniaturize my design into a compact and easily-produceable design. I do not know exactly what shape the design should take, so I am open to suggestions, whether it be soldered components or a complete PCB. The design will need to split mains power from a standard plug into three 'paths': one to the micro-controller at the appropriate rate, one to the SSR without any rating-change, and one to a powered speaker, again at the appropriate level. I will need help selecting and sourcing components as well. Inquire for more information!
