What to consider when beginning a custom electronic design project.

Designing a new electronic system there are always important factors to consider.  Outlining the ins and outs of the project functions from day one will allow for a clear path to development.

First things first what will the ultimate goal of the end product functionality be?  A general overview and a detailed project scope would be outlined.  This would summarize the 360 degree view of the project and what the final electronics will be required to aid in accomplishing.  It is a big picture process to determine what the expectations for the functions of the system are. 

For example you are designing a humidity minder that will monitor the interior humidity level for a various range of household and industrial uses.  To prepare a general overview it would be important to consider:

    • The ranges of humidity and what output displays would identify?
    • The type of buttons or controls needed?
    • What would the screen or visual aspects entail?
    • Power source?

The detailed scope would dig deeper into the electronics.  Every design project will have different criteria.  Some may rely on the expertise of the engineer developing the schematic of the electronics to suggest educated solutions for the best flow.  Others may have a very specific specification sheet covering each detail and the engineering team will work within those confines to make a system that meets the challenge. 

    • Inputs/Outputs – USB?
    • User Interface?
    • Power?
    • Physical Constraints?
    • Budget?

It is important that the custom electronic design process exhaust as many questions, challenges, and scenarios at the onset of the project.  While this can seem like an obstacle at first it is important to remember that this will limit the time and help to stay within the budget by being prepared.
