Electronics class Sunday 2pm: Oscillators

This Sunday, there will be an electronics class meeting from 2:00 to 4:00.

Last week we covered a lot of theroy, and in the end build a single transistor driver for a piezo buzzer. We connected these to a function generator and made some audible beeps.

This week, we will be building an oscillator so we don’t need the function generator. We will talk about capacitors along the way, and go in to detail about how a nontrivial circuit works: the astable multivibrator. This is the same circuit we used to flash two LEDs a few weeks ago, but this time we will be making it oscillate at audio frequencies.

Anyone (member or not) is welcome to attend.
