I need to use an existing certain chip to build a small device (roughly the size of 1x2x0.5 inch). The company who builds this new chip also provides an eval PCB, fully working and doing mostly what I need to do, however the PCB is too big and has some things on it that I don't need. Some knowledge of IEEE802.15.4-2011 UWB compliant, wireless transciever based techniques is a plus (the chip already does this, but the rest of the board needs to interface with the chip). I need someone to help me understand how I can condense their eval kit in to as small as possible and remove some of the components to help in this. I also need help in integrating a battery and MAYBE bluetooth (may not be necessary as it already has USB). I need the new version of this PCB designed in a way that I can just take a CAD file to a PCB printing company have have this manufactured in quantities of 100s or maybe even 1000s. I need someone who will work under a strict NDA, non-compete agreement and someon...

I am a practicing dentist and am attempting to improve on my LED lighted loupes which I use daily. I currently have some renderings, a designed circuit board, CAD drawings and circuit diagrams. Unfortunately the engineer who I had been working with has had some health problems and is unable to continue. He provided me digital files of all work performed thus far. I have a number of solid work files that I do not have the ability to view. At this time I need someone who can review the above items and see where I am in my project and whether or not they are viable. If they are viable, I would like an opinion as to the next step and possible manufacturing/production of said project. I am also interested in some patent protection of the prototype.

I'm in the early stages of developing a kind of pedometer, but for aerobics (like, calculating number of jumping jacks and other yoga exercises). This is a straightforward design, so ideally if you have already designed a bluetooth 4.0 circuit you could modify it to meet these requirements: 1. NRF51822 2. Accelerometer (MPU6050, etc.) 3. Button cell battery holder 4. All components in line (Acc <-> NRF <-> Button Cell) because it will be a wristband. The less width the better 5. Antenna components can be cheap as long as it can communicate with a nearby phone after exercising I plan on having this made on a flex PCB to bend with the wristband shape.

Hi there, I'm the cofounder of a start up called Enki Stove, we design and manufacture new technology biomass burners. Our systems works with low voltage used mainly to run a fan. Our last product called EnKi StoveŽ Wild comes in a kit: - Stove\burner (with built in fan and step up circuit DC to DC 5v to 12v) - Power Bank 5v 5000 mA - connection cable (usb 2.0 cable extension male to female) - and bag Well, here is the necessity to have that fan dimmable, that allow us to control the flame intensity. The idea is to integrate in the cable a dimmer from 0 to 12v Hope you can help me. for more information visit enkistove.com Thanks Davide

I am looking for someone to make a very simple analog sensor wireless with a tiny, rechargeable digital i/o board. Able to communicate in real time with an arduino to output time stamped data. I also would like a simple graphical output (can be built in Processing or Python or whatever you wish). This should be a simple job for someone familiar with arduino and embedded systems. If this works out, there are other assignments which could be forthcoming.

I would like to produce a book that reads stories out loud, similar to children's books that have farm animal sounds, but with sleeker/thinner electronics. The final product will read out around 2 hours of pre-recorded audio, have headphones, a way of detecting where in the text the reader is, and long battery life. I am looking for an electronics designer who can design the thinnest, most elegant solution and coordinate the Chinese/other manufacturers to deliver the design.

This project is specifically for the optimization of a Serit SP2636 Tuner using the ST Chip sets STV6110A and STV0903. We have the circuits working but do not perform as good as another similar system that we built. The Serit SP2636 is equivalent to the Sharp F7HZ0169 tuner can. The will require an advanced knowledge of DVBS2 circuit design including external hardware and the ability to optimize the software until the performance of this Tuner PCB matches our previous design. Experience in this area is a must.

We are looking for a talented FPGA programmer to help us implement a low noise (<10nV/(rootHz)) lock-in amplifier for heterodyne detection of sideband signals. Carrier frequencies range from 0.3 to 1.5MHz. The lock-in amplifier must have the ability to generate signals at specified frequencies and demodulate signals at the sum or difference of two frequencies (FM/heterodyne detection). Your job will be to develop a working prototype that does the following: 1) Takes in signals via a high speed, 16bit ADC 2) Generates a sine wave with programmable amplitude (ranging from 0 to 5V) and frequency, f2 = (1 to 1000Hz) 3) Demodulates the signals at two frequencies f1+f2, f1+2f2. f1 is determined from the ADC input. f2 is the frequency generated in step #2. 4) Outputs the RMS amplitude of the two demodulated signals via a low noise, 16bit DAC. We have an ADC and FPGA eval board already chosen, part #'s AD9268 and HSC-ADC-EVALCZ from Analog. You will need to help us choose the DAC and fi...

We need a working prototype of an kitchen appliance. Professional candidate will start with a document describing how the appliance works and design a circuit, prepare a PCB layout and built the prototype. This prototype involves a infrared sensor, thermostat, fan and a hotplate. This product requires two inputs temperature in Fahrenheit or Celsius and distance in inches or millimeters. Based on input values of temperature and distance, output is varied. Output controls the speed of a fan and resistance to the hotplate. More details about the project are available after signing a confidentiality and non-compete agreement.

I will be in need of someone to help me with a project tomorrow. One of the members in my group had something come up and the remainder of the team members and I have our hands full. We will need someone to help with a shallow foundation design so that we can present Friday. We are all getting together tomorrow at 9:30am eastern and would love to chat over Skype to get some guidance as to what formulas to use and how to go about approaching the problem. We are not asking for the work to be done for us, rather, just some help on how to get it set up so that we can plug and chug from there. We all have our hands full and could really use help for our design project.

** NOTE: WE WILL REQUIRE A NDA TO BE EXECUTED BEFORE JOB SPECIFIC ARE RELEASED ** Looking for an expert in programming hardware components. Ideally, you will integrate and program the following: Arduino (if you recommend something else, I will entertain idea) with the following components: - Bluetooth - Accelerometer - motion sensor - proximity sensor - magnetic switch - temperature sensor Once put together, this system will execute actions based on specific input from one or more sensors. Example, when accelerometer indicates specific motion, do this, or activate another sensor. Ideally, once a developer is chosen, I will provide list of component types that would be needed. The chosen developer will have the experience to find and select the most appropriate component from any of the dozens of online resources and recommend. I will then purchase and mail them to you, or will reimburse them to you. The final goal is for you to design, build, program a complete product based on my...
