The Tzatziffy has a build-in 3W audio amplifier that can be connected to some small speakers and sometimes its handy to control those speaker not via software, but via hardware. The Tzatziffy has a external control port for this purpose and I’ll show you here how to use it.
The first step is easy, I’ve removed some insulation and tinned the wires a little bit.
The default configuration on the Tzatziffy is to bridge the external potentiometer connections, so my second step was to cut these two brides. They are highlighted in the silkscreen with a little dash as shown on my blade and a little below.
My last step was to connect those wires to the potentiometer. I’ve combined both right pins of the potentiometer and connected them to the pin with the label “G”. The center tabs of the potentiometer to “Li”/”Ri” and the left pins to “Lo”/”Ro”. I’ve connected the left to the upper deck and right lower but that doesn’t matter at all.
Here is a small clip in action
PS don’t forget to unmute the speaker first
