Hey that sounds great! I've also just circuit bent a buzz, but even though its such a simple circuit I couldnt get anything like what youve got out of it
But its only my 2nd ever bend so hey.
All I managed to do is get a pitch control by swapping the resistor for a variable. May have another play with it later.
Im building buzz into my vtech laptop thing as an added extra feature
Plus- How dissapointed was I to find that the '3 buttons' buzz sports on his chest acually just press the same button on the circuit board, LOL!
