1 Input – 4 Outputs Stereo Audio Splitter

1 Input – 4 Outputs Stereo Audio Splitter

This 1 Input – 4 Outputs Stereo Audio Splitter has a single input and 4 independent outputs, each amplified with an operational amplifier. Each op amp is configured as a voltage follower, to take advantage of its high input impedance and low output impedance, thus avoiding distortion in sound.

Differential Temperature Controller (PCB)

Differential Temperature Controller (PCB)

Differential Temperature Controller.

This circuit measures the temperature difference between 2 sensors and activates a relay when they are different. It is also possible to detect a temperature change, even when the two measured temperatures are normally different.
