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 […]

10V to 350V Adjustable Regulator DC Power Supply
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 […]

5 volts DC Regulator Without Transformer Using MOSFET
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 […]

Dual DC power using 2 terminal transformer
There are many ways to build the dual power supply from a transformer that has one secondary coil.This good way as Figure 1 use two bridge diodes. The first section is normally working, others section (D1-D4) will work by AC signal from C1 and C2. To filter DC voltage of out others bridge diode of […]

Super Steady Zener diode circuit
This circuit is used for controls the voltage battery is steady, which the zener diode apply very low current about 1mA only, cause there is ripple voltage about 1 mV at voltage changing between 10 to 30 volts. As circuit the output is fixed to 8V. In circuit the reference voltage is connected to input […]

Constant current circuit using LED
Normally the voltage drop across LED while forward bias will be about 1.2 to 1.4 volts depend on type of LED by has the temperature coefficient is -1.5 mV per degree Celsius. Which similar to the temperature coefficient of junction. between a base and emitter of silicon transistors. From this relationship can the constant current […]

Many the 12V 1A power supplies circuits
Mr jafar need to use the 12 volts 1 amp DC Power Supplies. In my sites has many circuits related them. - Cheap and old but sure, use transistor and zener as main http://www.eleccircuit.com/simple-regulator-by-transistor-c1061/ http://www.eleccircuit.com/dc-power-supply-9-volt-using-tip31-transistor/ - Cheap and popular all times, use IC7812 http://www.eleccircuit.com/regulator-5v6v9v12v-1a-by-ic-7805780678097812/ Note: If you have a 1A normally circuit. So your 12V […]

i MADE A MISTAKE PLEASE READ 2022 and not 1022
I need the diagram of this power supply to repait my unit. This power supply is formy TX/RX radio, i need 13.8 volts 20 Amps, According advertisement i have bought a new one (Nissei PS30SWII) quite cheap 95€, but I want to get the old one repaired and to use in in my workshop.
