Project Description

We have developed a cheap way to interface a sensor to a phone. We want to build a prototype. This project will consist of two phases. Prototype 1 will use thru hole components and be manufactured using this process:

I have access to a laser cutter and I like to build things.

The second stage will add some functionality and redo the board for manufacturing at a board house. It will use surface mount components. No components smaller than 0603.

I need people with these talents:

Good English Communication Skills

Ability to understand instructions and perform accordingly

Analog Electronics Design (this is an analog product. NO DIGITAL)

PCB design

I'm including a schematic. It has two known issues with the circuit which heats the sensor. Read the data sheet for the sensor and the schematic. If you can tell me the problems with the heater circuit it will highly influence my decision to award the project.

If you don't have the skills required, don't bid. I will not pay anything up front. I will only pay when useable designs have been delivered. If you can't do this project, then it will be a waste of time for us both.
