This article show how to make one LED Strobe Light Circuit which uses famous chip named IC 555. Some knobs and resistors are used to control how much light and how fast it blink. One resistor also control the power which connects to LED. This project uses one special switch and this switch can handle […]
Simple High Voltage Generator Circuit
Anyone can learn how to make a Simple High Voltage Generator Circuit and this generator makes a very high frequency power. This article tell how to build this type of circuit . These things are not easy with normal power supply. One good thing of this high frequency power is that it does not give […]
500 Watt Induction Heater Circuit
This post is about 500 Watt Induction Heater Circuit Coil makes strong magnetic field and it changes very fast. When metal connects inside a coil then the metal becomes hot. This happen because of eddy current which goes round and round inside metal. Metal also heat up little more from its own property but that […]
Stun Gun, Taser Gun Circuit
In this Stun Gun Taser Gun Circuit, Tasers which are also called as stuns give big electric shock to stop bad person. Shock is to scare and hurt but not to kill. Bad person may not be position to control his body for few seconds after shock. That time we can run away. If shock […]
Light Up Simple LED with Weak 1.5V Battery and Joule Thief Circuit
This easy LED circuit with Joule Thief can make light from weak 1.5V battery! It work with white, blue and UV LED. We just need low power battery like 1.2V. Nice thing is LED still glow even if battery is very low like 0.4V. Now we can use old battery which people throw away! WARNING: […]
220V SMPS Circuit using One Transistor
This article teaches how to make 220V SMPS Circuit using One Transistor, it connect to wall socket of 220V and only uses one transistor called MJE13005. No need for special chip or many extra parts to the control power. It uses one special diode and wire coil on transformer to control voltage in different way. […]
