Updated bid for additional windows program and usb interface... I have edited the bid by adding cost of PCB fabrication, Component purchase, import costs, assembling cost, testing cost and shipment. Please note that we use all DFN components to make the size very small. So the assembling and fabrication cost are high. ...... Hello, Thank you very much for your invitation. I am a post graduate in electronics engineering with 12+ years of experience. I am running a company based in India with small team of engineers with different stream of skillset for all latest requirements in electronics projects. We have done many similar projects for different clients in freelancer and outside. I am sending links of some of the prototype videos related to your requirements. Please watch all the videos and you can get a clear picture about our skillset. We have done Bluetooth 4.0 based projects a couple of times. We have a a basic application on iOS for communicating with the device. We can provide the Xcode source code also for that program. You can understand it when you see the videos. We cannot do anything on the iOS side except we provide a working program to communicate to the device. Any iOS expert can alter the program and customize based on your specific requirement.

Hi, Reading your project description I found it is almost matching my last two projects combined together. I am working now on a battery powered Bluetooth 4.0 sensor (CC2541 based). The project is in the final stage - the hardware is done and tested and the firmware is done as well for prototype quality. The second project was a temperature controller based on ADS1120 - 16 bit ADC, where I developed hardware and firmware as well. So gluing together these two things would create exactly your device. I have bare boards for both and can assemble a proto quite quick literally gluing them together. My problem is I don't do IOS development and have no mobile target to try. This is why I added ~$250 for an iPAD Touch 5th as a target device to deploy the app. For more information check my profile. If you consider this information valuable please get in touch. Regards, DSnejko.

Hi, Is this work is relevant to me? Please answer me, I am serious engineer with results. I can design for you a board with interface to a GSR. I have experience with digital design with communication and all peripherals, so I can choose for you the right BT chip and interface with data acquisition to the GST in order to transmit it with the BT. Regarding to the X-code and the app programing, I am no app programmer but I can demonstrate a communication with a IOS based iphone. I could also activate sub-contractor to do appropriate app for you - if this are you intentions. Please send me the type of the GSR you are going to use and I can start working immediately. I will try to make a prototype on a breadboard in order to test it first and then I will do a full layout and produce a nice PCB. Amir

Hi! I saw you invited me to bid on this project, and I appreciate that; I believe I should be able to get a galvanic skin response sensor working well, as well as designing a iOS app for response output. If you haven't seen my profile please do. I am a US professional engineer and have electronics and mechanical experience professional in the aerospace industry as well as a lot of personal and custom hobbies I have learned over the years! However this project is quite a deep involvement of electronics and for a well designed and polished iOS too, the budget you posted is small compared to what you would pay an engineer for a quality piece of work. I am willing to put all my effort into your project but you need to reconsider the budget a bit. Please message me if you would like to discuss before choosing a bidder! Thanks for considering!
