I am taking an introductory course on digital electronics, and all year, we have used a breadboard and we have used a breadboard companion all year for a power supply. Now, for our final project, we are expected to have our own power supply, and I'm not sure how to go about building one. The power supply we have been using is below:

You could use the LM317, there's a calculator to help you calculate the resistor values on in the tools section of this site.
How are you going to be powering this circuit?
If you're going with mains then you'll need to use a transformer, rectifier and filter capacitor but be careful with mains voltages. You might want to use an enclosed transformer such as the type used to power halogen lighting.
How much current does your power supply need to provide?
