Let’s be honest here: one of the first things we all did when we came across speech synthesizers like the Speak-n-spell was to try swear words. [Alec Smecher] has taken this to heart, building a simple buzzer mechanism driven by an ATTiny 85 that swears repeatedly when you connect it. It is a rather simple project (or, as [Alec] himself says, it is “a satisfyingly minimalist build”), but it is quite nicely done.
The 8kHz speech sample (taken from Google Translate) is stored in the code, and written out to one of the PWM outputs of the ATTiny85 from a timing loop to directly drive the small speaker. So, all that is needed is the buzzer case, a small speaker, the ATTiny85, a power source and a few bits of wire. It’s a great example of a minimalist design: the ATTiny85 can just about drive the speaker directly, and can be run directly from batteries without requiring a power controller. Sometimes it pays to keep things simple, especially when it comes to swearing.
