To begin with, this Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change; also the transistor work like a door and if temperature changes it opens or closes for electric. So […]

Squelch Circuit
Squelch circuits are like the radio peace assistant!; and this small smart circuit stops radio sound when no strong signal connects. So no more hearing of bad noises but only when signal is strong one can hear good sound or video; also the best thing about squelch is its very easy and works with many […]
Touch Controlled Potentiometer Circuit
This Touch Controlled Potentiometer Circuit one just need to tap it and it will start to work; also there is no need to turn knob or move the slider it just touches the sensor and it changes the resistance or voltage. Furthermore, it uses capacitive sensing which means that when one contacts it, the body […]
Multi-Tone Electronic Siren Circuit
In this article for Multi-Tone Electronic Siren Circuit make it more fun with one siren circuit that makes many sounds. Also, this small thing work like alarm sound toy which is good as warning. But not just one boring sound it makes many loud noise one after one or same time!; and it works well […]
AC Drill Speed Controller Circuit
Now one can control its own drill; in this article for AC Drill Speed Controller Circuit is like cruise control but for drill. Furthermore, it helps one to change motor speed, so one can work better for any job, also very good when one is doing soft work like wood or metal but need careful […]
Car Antenna Amplifier Circuit
Car Antenna Amplifier Circuit is a small box that helps the car radio catch signals better; also, radio signals are sometimes very weak like a soft whisper, so the radio does not hear them clearly. Amplifier make whisper loud so radio can hear clear, it is good for places where radio station is far or […]
