The goals of ECE 112, Introduction to Electrical and Computer Engineering are: (1) to introduce basic concepts in Electrical and Computer Engineering in a integrated manner, (2) to motivate basic concepts in the context of a simple student constructed robot, and (3) to illustrate a logical way of thinking about problems and their solutions.
The mailgroup is how I communicate with you outside the classroom. It can also be used as an interactive forum where you discuss homework problems and solutions. Such usage is encouraged. You are welcome to discuss homework solutions or approaches to solving a problem.
Students who register early for ECE112 during the fall term are automatically given ENGR computing accounts and are added to the class mail list. You will receive a notification from the list manager when you are added to the list.
The name of the class list for ECE112 is: class-ece112@engr.orst.edu This name is case sensitive.
Lab Kit Costs (2004 prices)
Robot kit : $60 ($20 cheaper than last year)
Tool Kit: : $15 ($5 more than last year)
The Robot kit is the only mandatory purchase if you are proficient with soldering and have your own tools. We will be selling the required tools and robot kits during the first lab session during the week of Janurary 4th. It is very important that you bring $60 or $75 dollars cash or a personal check with you to the first lab session. Only cash or personal check will be accecpted. No exceptions.
If you have the proper tools to build the kits, you do not need to buy tools. Here are the tools you will need:
Tools needed
* Flat Head Screw Driver
* Philips Head Screwdriver
* Wire Strippers
* Side (diagonal) Cutters
* Needle Nose Pliers
* Solder Wick ( we supply the solder)
* Digital Multimeter (DMM)
* Safety Goggles
Soldering irons are supplied in the lab. We will be using industrial quality irons to make learning to solder as easy as possible.
If you have never soldered, don't worry. We will teach you. If you once knew but have forgotten how to, you may want to review a soldering tutorial we have: soldering tutorial. This is not a soldering class, but it is a fundamental EE skill that everybody should be proficient with. Besides, its farily easy to learn.
If you have all the tools and also a soldering iron, you are free to work on the robot kit at your residence.
All lab sections meet in DH302.
Lab Conduct
No food or drink is allowed in the lab. No horseplay is allowed. Take care of the lab equipment. We can have a
fun time if we act like mature adults.
If your grade does not show up by Saturday morning of week "n + 1", notify your TA immediately. If you don't get satisfaction from your TA within a couple of days, let me know.
If you have a missing grade but neglect to tell anybody about it for more than 1 week after it should have been posted, it will be too late. In other words, you have one week to complain about a missing grade. After that, its too late.
If you don't pick up your homework in lab, it will be held there for 1 week and then discarded.
Across the top of each page put:
Lab Section # Homework # Name last 5 of student ID
I strongly encourage you to work all of the problems till you understand them. Just watching me do them on the blackboard will not be enough.
The exam questions will be taken from the problem sets with minor changes. The exams are constructed such that if you understand all the lecture material, and can do all the homework without help, you will do well.
Homework solutions will be made available on a timely basis (as I can get them done) so you can check your homework procedures and answers.
