Hi,
We want to make a simple device. It's a sensor connected to a 555 timer acting as a VCO. There is also a simple NPN transistor which is sometimes turned on. The whole device is operated using usb power from a cell phone and the audio input/output of the cellphone. The audio turns the NPN transistor on. The audio records the output of the 555 timer.
We also need a board designed.
It should take less than a week to complete the project. We will discuss it in more detail if you have a nice bid.

Hello sir.
I have master degree in electronic, and this is pretty basic project.
I can fully finish you'r project for several hours.
I offer you cheap and reliable design, and i guarantee you for quality of design.
Also i will fully support you to the end of project.
Feel free to contact me.
Bye
This project shouldn't even take a week. I have all the parts laying around, I can put it breadboard and give you a video showing it working and then proceed to a PCB layout using eagle. It's sad how many engineering graduates these days might suffer with such a project!
It's pretty good project i am also looking for this kind of project. I have very strong grip on power electronics device. i can do that. For further satisfaction check my profile.
