During the next lab exercise on measuring DNA melting curves, you will build and debug several electronic circuits. This assignment will introduce you to the electronic components and test equipment you will use. This bootcamp requires an understanding of basic circuits. If you need to review circuit concepts, start with the Electronics Primer page. If you have a lot of experience with electronics, ask one of the instructors about doing a stimulating mini-project instead of the mini-lab assignment.

A short answer-book style writeup is required. Your writeup should include the practice problems and any bolded questions asked throughout the lab instructions. Don't forget the basics: report measurements with an appropriate number of significant figures, units, and uncertainty. Label plot axes.

Assignment Details

This assignment has three parts:

  1. Part 1: A few questions to answer before you start your lab work.;
  2. Part 2: Get in the lab and start building and measuring basic circuits;
  3. Part 3: Build an amplifier circuit that you'll use to measure the amount of fluorescence from your DNA melting samples.
