multivibrator
My first cricket circuit board arrived today and it chirps!
Astable multivibrator circuit built with discrete transistors. The circuit generates a waveform that sounds like a cricket when applied to a piezo electric buzzer. Kelly Heaton, 2018
I did make one error in my schematic, which involved the reversal of the PNP transistor (3906). Thankfully, the wiring worked perfectly when I turned the PNP in the opposite direction.
Unafraid Field Cricket, 2018. Analog electronics, watercolor, and graphite on paper. This little analog electronic cricket painting is "unafraid" because its sensor is pretty insensitive. The speaker element is a deconstructed RadioShack piezo electronic buzzer (with some blue paint to knock down the white rubber ring - see detail on right).
Astable multivibrator with big blinkers (can't touch this woman), 2018. Watercolor sketch on joined paper.
