how can you have fun for two hours ?
I kind of find an answer, build a electronic snare drum ! (build isn’t the word, breadboard is actually ! )
the one built is the snare from the famous TR808 (that people can give a absurd amount of money to own).
not too much complicated, the noise adder is also interesting (Q47/Q48). I triggered the sound with a push switch a cap and a diode (and also from function gen)
now, the drawback is I’ve to remove all components from the breadboard and decide if I build that stuff on a verboard. A electronic drum machine triggered by sticks is a cute idea. (not new at all but cool anyway !). I’ve to think about it …
there’s also good explanation of this particular circuit at Mr Archer :
