Depending on your application, this simple “Joule thief” circuit may do the job:

It’s self-exciting, and uses only one transistor.

My company sponsors projects centered around the vehicle diagnostic bus (OBD-2). It can be a diagnostic scan tool, a remote control that does not require modification to existing wiring, an MPG meter, or whatever else you can think of.

Cory, you omitted several important pieces of information:

- Where are you located? – What kind of work are you looking for? – What skills & abilities do you bring to the table?

Andrew, of course if there are no other options it makes sense. However, I’m sure there are other engineering opportunities in your area. I believe that it’s important to be happy at your job, after all this is where you are spending a big chunk of your waking hours. You also tend to be more…

I’m curious why Andrew continues to work for a boss he despises, on a project he does not believe in?

Once Steve finds this article, I’m guessing you’d be changing the title to “The hilarity that was my part time job”. :)

Do you plan to use a wired or wireless interface for OBD-II?

There are many different kinds of OBD interfaces, but they can be broken down into three general categories: off-the-shelf interfaces, OBD modules, and OBD ICs (chips). To choose the right OBD interface for your application, you must consider a number of factors, including:

• Cost
• *Time to…

OBD stands for “On-Board Diagnostics.” It is a computer-based system originally designed to reduce emissions by monitoring the performance of major engine components.

A basic OBD system consists of an ECU (Electronic Control Unit), which uses input from various sensors (e.g., oxygen sensors)…
