Bluetooth small motor vibrator controller using audio signal

i can give a video with the system over atmega8 micro controller and Bluetooth module , the project will run with this idea, the data of the sound come with reflect to the amplitude of the sound , higher sound more vibration, lower sound , low vibration

hi, i am an electrical engineer. i have expertise in embedded system design.i can help you with this project. i have extensive experience with Bluetooth designs. i can provide you a small and durable design for the bluetooth audio vibrator. also a good quality of battery charger will be included. The Topology of the design will be simple, The bluetooth chip will connect to the smartphone with A2DP profile and audio played on the phone will be played on the Vibrator with proper voltages. for my quoted bid i will provide: 1) schematics 2) PCB layout 3) Firmware 4) BOM and gerber files 5) one prototype system i can also help you with the manufacturing of this product. My milestone breakdown would be as follow: 1) initial upfront 40% 2) upon completion of the Prototype before shipment. 40% (shipment cost not included) 3) when you receive the prototypes and test it fully on your end. 20% Please check my profile for my previous work experiences. let me know if you are interested in the bid so we can discuss the details further. regards

Hi! My name is Keith, I am a professional mechanical engineer here in the US. I have worked with iPhone application, bluetooth, PLCs and microcontrolled devices, both in professional work and here on Freelancer for other project employers. Please see my profile for a bit of samples and don't hesitate to message me directly if you would like to ask any more questions before choosing a bidder! Thanks for considering! - Keith Becker

Hi, Is this project is still available? Am I relevant for this project? Please answer me. I can assure you good result that definitely satisfy you I understand well your description. I can design for you a system with BT signal analysis (for detection relative volume and spectrum data) and a suitable driver for a motor I have a lot of experience in designing digital boards with wireless capabilities, I will make it in 2 stages: First I will build a prototype on a bread board in order to implement the idea. After that will work I will design a PCB with all need components. I will make the SW programming my self (if need. I will try to make it simple, maybe with no programmable chip. I need to fully understand your requirements) Do you need it to play the audio as well ? Amir

Hello, I am an embedded systems designer and developer and would love to work on this project as have done several projects involving control with smart phones like Android based. I must clear that if you like to use Bluetooth for transmission medium then the circuit will become costly and it will also need a micro controller on the receiving side for pairing issues and also that the range of the device will be short and also that some smart phones like from apple will need to be jail broken to use blue tooth sound transmission. So, I have a solution for that which is not only low cost component wise and also that it will have a range of better than 50 to 100 feet. Kindly contact for further conversation and award of project. regards, Ali Khurram

The project mainly consists of : 1) Micro-controller 2) Vibrator motor 3) Bluetooth Module 4) Lithium Ion polymer battery We have previous experience in vibrator motor interfacing with the controller and mostly the vibrators are SMD and needs to be fixed in a board. We have also done interfacing with Bluetooth module through RS232/USB protocols. Please contact for the further discussion of the project.
