To give you an idea, here's a picture of my desk today:
I went to school and got me BSME, and I did very well in the electrical class we had to take, For some electives I took a C++ programming course, and a mechatronics course.
Also, I was heavily involved in our robotic combat team. It was through this team that I learned a lot working with people from different disciplines. Particularly art majors and EEs.
So I graduated with more electrical knowledge than 90% of all MEs who just graduated.
I now work for CNH doing technical support work for some of our machines (planters, combines, seeding equipment), and I love it. I never know what to expect in the morning, every day brings something new. I support everything from the old 1460 combine built in 1977, to the 9120 combine built in 2010.
Keeping up with the changes in the equipment, finding out what can be retrofitted, and what can't. Work with other people in the company to develop marketing material, service training material, and parts kits books.
Right now is kind of a slow time, so I'm working on a project to allow a combine engine to be run on a dyno without all the extra combine controllers. I have to find out exactly which CAN messages are required to allow the engine to run, get my chip to connect to the CAN network and communicate correctly, and send out the correct messages at the correct time as well as read in messages and interpret them correctly.
The chip also interfaces to an LCD screen to give a readout of critical engine parameters, and it has a set of LEDs to indicate errors and warning or shutdown modes.
But normally my job requires me to have a working knowledge of how the machine is supposed to function, then use the hydraulic and electrical schematics to develop a set of tests to determine which part(s) are not functioning correctly.
Also, I have to develop testing procedures to find out if the software in the controllers on the machine possibly has a bug in it. So I also have to know how the different controllers work together and how the logic in them is supposed to work.
Also, my group helps track problems that we see, and other people see.
To get an idea of our work load, there are 6 of us in the office (plus 1 team leader) to handle all the combine questions on Red combines for all of North America. Now add to that we support all colors of CNH planting, seeding and tillage equipment, and you can see that when it's busy, it's really busy.
