Hello all, I am looking for some help, over the last few months i have been working on a very modern and innovative pair of wireless earphones, like nothing else on the market today. They are tiny, but pack a massive punch when it comes to paying music and has a tonne of other functionality. The project is very exciting and we will be looking to lunch the product on kickstarters to raise some extra finance and awareness when the product is ready. At the moment we have a single non working prototype. What we are looking for is someone to completely design the electronics inside of these earphones. They need to be tiny so knowledge of small electronics is going to be vital. The pair of earphones are going to unitise bluetooth 4.0 and have adtx music quality. In terms of the power and processor thats open to you, i need to make these earphones as small as possible. Please let me know if you are interested and post a quote for the hourly rate and also the total value you would expect to...

I am looking for someone who is familiar with mircochip to design a circuit which can make use of a Barcode reader on USB port and read any data which is canned. I will need firmware and schematic for the same. I will pay only once i test the complete system In next part, I will also like webcam integration on same board with another USB port. But that will be separate project,

After a first contractor was incompetently slow and then sadly suffered a stroke literally days before it was hoped this project would finally be functional (he is still out indefinitely with a substantial sum of my money that may be forever gone now), and after a second contractor has now totally flopped with some more of my money while delivering nothing useful in time for an annual trade show (now over), I am now in a position where the patent protection period is half over for this system with nothing to show for it yet and essentially back to square one for finding a suitable contractor(s) to help. Time is now of the essence and becoming more critical with each passing day. This is a golf-related project that the industry needs very badly at this point in order to prevent the clubfitting trade from continuing its horrible and embarrassing performance record and reputation. Some knowledge of and/or interest in golf and the game's future might be a plus, but is not required and m...

We are looking to transmit signal from external machine such as xbox, dvd player, apple tv to our television without the use of wires. This is not a request for a HDMI dongle like chromecast. We would mainly be interested in just the development of the prototype we we can then mass produce overseas. We have included an attachment detailing our goal.

I need a low cost battery powered system to log the item/trash level in a bin and send the data back to a SQL server using GSM/GPRS module and REST API interface possible. Data is sent every 2-4 hours between 7am-9pm. I will provide server and web service. I only need the hardware and hardware code design. This instrument should be robust and easy to interface. The components for the hardware will be : a) Arduino / compatible microcontroller + pcb (extra low power and idle-able and power saving mode, onboard reprogrammable) b) Battery (last as long as possible, with minimum 3 months) c) Ultrasonic sensor or compatible sensor to detect the level. (outdoor usable & will be built inside a case & low power consumption & sense the distance between 10cm - 100cm preferably) d) GSM/GPRS module with embedded antenna for wireless data communication. (low power consumption, power saving mode, low data use, good signal coverage inside a IP67 casing) e) IP67 casing/housing. (optional) (...

We are a company that installs wifi networks for large buildings. We have a circumstance in a large building where we have an extremely high 2.4GHz interference. We are looking for someone who can help identify the sources of interference and possible solutions to attenuate the interference such as shielding. We have a Wi-Spy 2.4/5GHz Spectrum Analyzer and have taken recordings at different parts of the building specifically next to floors and rooms that contain large motors for water pumps and elevators. We are looking for someone with experience in identifying sources of interference. Please let me know if this is something you can help with. We need to begin working on this project immediately and would like to set up a meeting to discuss next steps. Please include hourly rate in your bids. Also include schedule of availability. Thank you and looking forward for you bids.
