An Example Junior Lab Talk. Chuck Rogers. Introduction : Say who you are Project Overview : What you wanted to do Circuit Description : Show the circuit and tell us what it does Circuit Performance : Tell us what worked and what didn’t Summary of major results Conclusions.
You want to describe what attracted you to the project, the circuitry that you tried to build, whether it worked or not, and any other noteworthy or interesting things that you discovered.
You have 10 min., say 8 min. to talk and 2 min. for questions. It flies by. You should expect that 1min. per slide is needed. You should practice your talk. Keep it inside the time limit. Toss material if necessary. Practice the talk again.
This talk has more text than is typical. Your’s should have more pictures and data. Here’s an example of a project overview:
“H&H suggested that the ‘Bad Idea’ circuits at the end of the chapters had some pretty funny examples. We decided to make one to see why it didn’t work (it looked OK to us) and to see if it was actually funny.”
Here’s a ‘Bad Idea’ circuit from the op-amp chapter. It
claims to be an ac-coupled, non-inverting amp.
Looks good to us!
Gain = 1 + R1/R2
It’s good to include some circuit theory and take the time to explain how you think the circuit should work. Use a couple of slides if needed.
REMEMBER: PRACTICE THE TALK AND FIND A WAY TO FIT IT INTO 10 MIN, ASSUMING A FEW QUESTIONS. Have fun!
