 5 volts DC Regulator Without Transformer Using MOSFET

Wednesday, October 22nd, 2014

This is 5 volts DC Regulator power supply that without the transformer so small size, use the MOSFET is based. It is suitable the digital circuit. Caution! This circuit requires very careful to create. Because there is a high voltages many areas. The diodes D1 to D4 are used to convert AC power line to […]


 10V to 350V Adjustable Regulator DC Power Supply

Tuesday, October 21st, 2014

Here is an adjustable regulator DC power supply circuit that can be provided the output high voltage is 10V to 350V. It use the transistor is based so we use often use them. Now, a transistor can tolerate more high pressure. For example; in this circuit we will use number of BU 111 or BU […]


 Electric fish shocker circuit

Saturday, October 18th, 2014

This is the simple electric fish shocker circuit or fish stunner. It helps in catching fish easier, it use 12V battery to convert to 220V AC. We use few parts so easy and cheap. How it works This circuit convert voltage from 12V battery to AC 220 volts. Both transistors will alternately work ON and […]


 NE5532 datasheet; Dual low noise operational amplifier

Friday, October 17th, 2014

NE/SA/SE5532/5532A: Internally-compensated dual low noise operational amplifier The 5532 is a dual high-performance low noise operational amplifier. Compared to most of the standard operational amplifiers, such as the 1458, it shows better noise performance, improved output drive capability and considerably higher small-signal and power bandwidths. This makes the device especially suitable for application in high-quality […]


 5 watts Class A amplifier using NE5532 and MJ2955

Thursday, October 16th, 2014

      Here is the 5 watts really class A amplifier using NE5532 and MJ2955 as based. This is best of quality sound.       We used popularly the many type of power amplifier. For example: Class A, Class B, Class AB etc. The Class A amplifier is the best of quality sound.       But the class A to the […]
