Automatic Dimmer Dipper Circuit for Automobiles
Automatic dimmer dipper circuit for automobiles is a simple and small device used in vehicles and it changes the headlight brightness automatically when another vehicle comes from the front. Furthermore, because too much light can make other driver blind at night and also this can make an accident. So main purpose of this circuit is […]
Bench Power Supply Circuit
To begin with, this project is for Bench Power Supply Circuit which is easy to use and works good and we can change voltage and see current. What is a Bench Power Supply: Bench power supply circuit is useful device which gives steady and control power for working in lab, workshop and testing electronics. Also, […]
High Current Adjustable LM317 Power Supply Circuit
In this post, IC LM317 is chip for controlling voltage but it give only 1.5 amp current, also we can add one more part called TIP35 transistor with LM317, in which LM317 tell it and this transistor act like a follower. Now with this transistor LM317 can handle big current up to 10 amp. Also, […]
10 Watt Amplifier Circuit using IC TDA2003
To make a cool 10-watt amplifier circuit using the IC TDA2003 is not very difficult; but in fact, this circuit is ideal for small projects for kids or beginners in electronics, moreover, it is quite simple and easy to build. Also, the TDA2004 chip is quite good and already includes many internal components for better […]
Automatic Bedroom Lamp Timer Circuit
To begin with, this Automatic Bedroom Lamp Timer Circuit turns OFF by itself and this is a very cool idea, but first we need to think about safety. Firstly, do not touch when it is plug IN as it takes big power from wall and also this circuit is not too hard. Moreover, when we […]
