This is a guide to the Instructables submitted for Electronics (Physics 128) at Pomona College in Claremont, California.  Students were given very little guidance on this project besides make something that uses electronics.  These projects were built over the last three weeks of a semester-long introductory electronics course.  This experience has taught me once again that the best thing I can do as a teacher is get out of the students' way. 

This project uses an Arduino, a pair of speakers, and a laser pointer to create a laser projector able to trace out designs in a dark room. To power it, I've cannibalized a PC ATX power supply capable...
