$30-250 USD

Paid on delivery
it is an electronic wireless control for running a dc motor vibrator from a portable audio signal like a smart phone. Imagine you play a music on a smart phone, through bluetooth this device is going to change that music to a vibration. The higher intensity of the music (averaging frequency) the faster the motor spin (thus higher vibration). using very easy pairing step of a Bluetooth wireless to receive the audio signal from the smart phone using Li-po battery source and last for 1 hour for 50% duty cycle rechargeable with a USB connection The design will have All component soldered in a PCB that would fit into a box with dimensions: 2" x 0.5" x 0.5"

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.
