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.

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.

The task is simple, recreate the teensy 3.1 with the same number of pins and specs, just make it as thin as possible using thinner pcb, chips on the back, etc. Bidders must provide evidence that they have experience designing and producing electrical chips. We need someone that can take this project through to a working prototype. If after thorough testing we agree that it performs to our satisfaction, we will look to produce the chips in some quantity but what you should bid for is just for building us a prototype.

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...

Our aim is to find a unique developer who possesses the skill and unique qualities to over deliver on both time schedule and estimated hours. We have continual business for the correct individual. The first project opportunity we will be testing the ability of the developer including time management and process of build. We prefer developers who have a good sound knowledge and understanding of hardware and firmware design and implementation. Job Description: Project is estimated to take ~4 weeks or less. Proposals one-liners may not be considered. Please, state your exact experience with CSR BLE.4.0. The first project is for a Ibeacon based design that we already have in place. We need to integrate one further sensor and firmware to this current design.

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.

** 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...

We are looking for an Injection Molding designer to design a case for our PCB. We have an example of what we would like the case to look like. You will need to take into consideration the smooth design and aesthetically pleasing aspects that we are looking for. However the goal is to have the design easily manufactured from an injection molding tool. So the Overall focus of the design is to reduce the amount of elements needed to create the tool that will ultimately produce plastic parts the make up the overall case. So we are only looking for experts with previous experience with prototype of injection molding
