We like to build a prototype product using fiber optics and by utilizing its highly sensitive micro bend multimode fiber optic sensor for simultaneous measurement of Breathing rate and Heart rate. It will be based on the technology developed by some of industry's current products. We have some published journals and utility patents information. And the we already had the design concept approved by several fiber optic expert. The right candidate need to review our design concept first,and working with us starting from scratch.The Target is to provide us a functional prototype(once the design complete we will have our in house technician build the prototype). The Key skills we looking for are: 1.Fiber optic expert:able to help has find right Fiber optic cable and associate fiber optic components. 2.Material engineer knowledge. 3.PCB design:PCB Design/Develop will be involved in this project. Firmware skills will be a plus. Labview experience will be a plus Wireless Design experience ...

We have two components that need to be connected together with proper power and programming interfaces. The PCB needs to be no larger than 2in x 2in. Ideally we would like to have a PCB antenna (2.4Ghz ZigBee), but will settle for a chip antenna if it means space savings. The RFID antenna will need to be PCB. There also needs to be a connection for an RGB LED. ZigBee System-on-Chip: Atmel ATmega256RFR2 RFID: STMicroelectronics ST95HF Battery: two 1.5v AA alkaline LED: Generic RGB LED

Design and build a hub that will receive data from various z-wave sensors (motion, door contact, temperature, humidity, etc.) and then send that data to our web based database via wifi. The hub will need to have an ac power source, receiver of z-wave, and wifi connection to a home network. The hub will have to have an easy method to pair z-wave sensors...and add the sensors to database. The hub will need to have an easy method to connect to wifi network- WPS or similar. The Hub production cost can not exceed 35$- so pay attention to wifi chip be used. The bid must include design, building 3 prototypes, shipping these to USA, and all firmware. Working prototypes must be completed within 14 days of project start date. Data transfer- The Api we provide will be POST method. The data will be pass in JSON format like following keywords { sensormacaddress: Datatype String, sensortype: Datatype String, batterylevel: Datatype Integer, sensorevent: Datatype Integer, year: Datatype ...

Hello I am in need of someone to create all the files needed for me to produce a simple ion meter (mv meter, potentiometer) Here is an example.   [obscured]  /proddetail.asp?parent=12&prod=377&seq=3&TotRec=9   [obscured]  -china.com/enproductsview/604.html We need to make a much simpler cheaper version. We have made a much more complicated 6 channel ion meter in the past. So to that end, I have all the design files, we actually have 2 different models, so the basically all the details are worked out, all the components, values and schematics and so on. What I want to successful elancer to do, is use the data on the files for the multi-channel projects we have already done. Use the knowledge to re-create the drawings, gerbers BOM etc, so I can have a simple ion meter made. The ion meter needs to work exactly as we have made in the past in terms of the components and schematics layout, i.e we have worked out how to make the mV meter. It works by measuring ...

i want to build a VCSEL driver that can drive the VCSEL at 120 Mbps at a low power consumption of 3 mW, this VCSEL should send the data accross skin and i want to see the transmitted data on the receiver from the other side of the skin. the space between the transmitter and receiver should not be more than 3 mm, and the skin should be in contact with the VCSEL. i want this system to be build on PCBs and i need it to be ready in 25 days if possible.

This project is to develop a sensor network system. The network will consist of many identical but configurable sensors wired together in a daisy-chain. The sensor PCB is already designed but needs to be debugged. Therefore most of the work will be in writing and debugging the firmware. Each sensor module will have a button for configuring the function of the sensor. For example one sensor might be configured to trigger an alarm when a switch closes. There will be approximately 17 commands related to sensor configuration and control. We are not using a standard network protocol. Firmware must be in C for an 8 pin PIC PIC12F1822-I/P-ND. The sensor network cable will have a total length of up to 500 ft so the firmware must consider noise immunity. Confidential details will be provided to qualified applicants after which you can fine-tune your bid.

This is going to sound weird. I want someone to take the pcb board of the Razer Blackwidow chroma keyboard, and possibly engineer it to fit in the casing/housing of the blackwidow tournament edition keyboard. why am i doing this you ask? because the regular keyboard is huge and a waste of space and i would like my keyboard tournament edition keys to light up with the chroma functions. not sure if anyone can do this. if you google the pictures of these two keyboards, you will know what i mean. basicly, your going to work with 2 existing functioning keyboards, and its kind of like a transplant with some surgery to remove unwanted parts.

Design and prototype a simple optocoupler PCB that features two board to board connectors and a MIDI connector. It functions in two ways. It either receives the digital output of a microcontroller (Tx) through one of the board to board connectors and sends the data through an optocoupler (maybe 6N137) to the MIDI connector, or it receives MIDI data and sends it through the optocoupler to the other board to board connector. The board gets powered through one of the pins of either board to board connector. Which way it functions is selected by a slide switch. Straight forward and simple job.

I am interested in designing, developing and manufacturing a RECEIPT size ONLY document scanner proto-type using off-the-shelf electrical and electronics components. Here is a brief functionality description: Upon sensing the paper in the feeder auto start the scan and store the file on SD card in JPG format. There is NO USB port required for file transfer. Only 2 ports required are: for charging the internal battery and the SD card slot. I am developing this proto-type for a project which will require 100 scanners. Upon project success many more scanners will be required. I need quotes for the design, development and delivery (California, USA) for 100 such scanners. If possible, do give quotes for 2-3 variations of the components / functionality. Contact me for any additional considerations needed for making scanner more efficient or cost lesser. Budget in the job description is indicative. The details specs are below. Paper sensor: mechanical or optical Auto launch / scan star...
