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 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.

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...

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...

Looking for a freelancer/company to help us design a circuit for a physical game for kids, involving lasers, mirrors and light sensors. The game is a sort of puzzle where the player needs to make a laser beam reach a light sensor by moving small mirrors to reflect the light. It needs to be hooked to a raspberry pi or alike to control the game logic. The game size is approximatively 4m x 2.5m x 0.5m. You will help us translate our concept into a working installation, define what is possible or not, select the components and design the circuit. We will also need wiring diagrams and specific instructions to provide our local contractor. Optionally, you could also provide us with some basic code to run the circuit.
