Physics 331 - Electronics Lab
Final Projects - Spring 2022
Due: Tuesday, May 17

Your final lab of the semester is to build a circuit of your own design. You could build a more complicated circuit related to things we have tried in class, or you might choose to build something that you would be interested in, that might be useful or fun to you. You will research a design, build a prototype on a breadboard, and then a final circuit soldered permanently. You will do an oral presentation to the class on your circuit; you should consider including some background or history, if relevant. You should also simulate the circuit (or appropriate parts of it) in circuit simulation software.

Please note that it is a frequent occurrence that a student gets their circuit to work (perhaps on the prototype, but not soldered, or perhaps it works one moment and not the next). At the moment your circuit works, if I am not present, you will want to document that with something like video so that you can prove to me it worked in case it does not work later.

** Deciding on a circuit:  I will not approve something completely trivial; I expect it to be somewhat involved with numerous components - it must have a minimum of 20 electrical/circuit connections.  You may make your own design, but more likely you will find a design that exists. Be sure to search the Web and the books I supply. Some good websites for circuits:

I also have six Radio Shack "Engineer's Mini-Notebooks", and two "Evil Genius" books that might be good references.
