Small Amplifier Circuit using Transistors
This is one Small Amplifier Circuit using Transistors which work like basic audio amplifier. It makes weak sound signal more strong so sound come better like in car radios. Now lets see how this circuit is build and how it work. Circuit Working: Parts List: Category Component Quantity Resistors 100k 1/4W CFR 1 1k 1/4W […]
220V SMPS Circuit using One Transistor
This article shows how to make 220V SMPS circuit using one transistor, as the circuit connects to 220V wall socket and it uses only one transistor MJE13005. Also, no need of special IC or many extra parts, instead, it uses one special diode and transformer coil. So, voltage is controlled in different way and as […]
Electronic Organ Circuit using Transistors
This post talk about how to make small and easy Electronic Organ Circuit using Transistors. First, it make sound like real organ, so sound is nice and fun, then we have used transistor and transistor help make sound and give power to speaker. Also, this circuit is small, but it plays good music and is […]
1 Watt Hi-Fi Amplifier Circuit
This is small 1 watt Hi-Fi amplifier circuit which gives 1 watt sound power, so it is good for small speaker or DIY audio project. Sound quality is clear and nice and even if power is low, but circuit still work good. Also, this type of circuit is easy to build because it uses simple […]
