a log to keep track of my analog-synth experiments, that i’m doing outside of any class (but combining the things i learn in class).
two transistor metronome:
originally found in forrest mims circuit scrapbook.
all pin outs are how they would be when you face the component. you can also place an led to show the signal directly between pin 3 of the pnp and the speaker.
fried transistors in the process:
soldering attempts:
happy with my soldering:
note to self: always have a diode to prevent audio-signal cross contamination.
made a filter with an op-amp, for ss_experiments_week-4-&-5.
luke dubois suggested that i buy pcb-mountable potentiometers, and power the whole thing with a different jack.
