Benedini Mixer

Electronics

I have just purchased a Benedini TBS Mini sound unit which I intend to use in one of my Stuart tanks, this sound unit when in 'Autostart' mode only has one input from the receiver to determine the engine speed/sound, my tank is using two speed controllers and I need to mix the two channels together so that the sound unit always receives the largest signal (hence the higher speed/louder sound) in both forward and reverse directions from either channel.

I have since foundout that the TBS Mini can do this itself, a programming cable is needed and the software. Or ask for it to be setup how you want when you order it.

Components - PIC 12F683

0.1uF Capacitor

8 pin DIL socket
small piece of veroboard

3 servo extension leads

DIL header strip (6 pins)

This is a very simple design and easy to make on a small piece of stripboard using only 6 strips and requires only 3 strips cut, shown by red crosses. Diagram viewed from component side e.g. above PIC
