Headphone Amplifier with IR Communication

This low cost project can be used to reproduce an audio from TV without creating any disturbance from other people.

Clap-Sensitive Relay with ON/OFF Feature

Clapping of hands is the main idea on how this circuit was built with the acknowledgement of a relay to cause the circuit to function with ON/OFF feature.

Thermostat Heating System

The purpose of the creation of this circuit is to provide a control over a central heating plan or a heating system by maintaining the indoor temperature at constant value regardless of the temperature change from the outside.

Touch Controlled Capacitive Sensor Circuit

The circuit was specially designed for shop windows animation as it makes use of a capacitive sensor that is triggered by touch control system.

Digital Selector with 8 Sources

The objective of the circuit is to develop an electronic selector coming from 8 sources with an up-down motion in series.

Window Switch Sensor Based on Temperature

The circuit has been designed to produce a window switch with the use of a thermistor for the main purpose of sensing temperatures.
