Do anyone want to try make its own small radio station?, then this post can help, this post show how to build a easy and FM Transmitter Circuit (100 meters range) which works between 87.5 to 108 MHz on FM radio. Transmitter uses simple circuit with special transistor and antenna to send our signal, but […]
LED Strobe Light Circuit
This article show how to make one LED Strobe Light Circuit which uses famous chip named IC 555. Users use knobs and resistors to control light intensity and blink rate, while one resistor also controls the power connected to the LED. Also, this project uses a special, high-power switch, if possible, use this same type of […]
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, and this article tell us how to build this type of circuit, as these things are not easy with normal power supply. One good thing of this high frequency power is that it does […]
500 Watt Induction Heater Circuit
This post is about 500 Watt Induction Heater Circuit, coil in this circuit makes strong magnetic field and it changes very fast. When metal connects inside a coil then the metal becomes hot and this happen because of eddy current which goes round and round inside metal, metal also heat up little more from its […]
Stun Gun, Taser Gun Circuit
In this Stun Gun, Taser Gun Circuit, people use Tasers (or stuns) to deliver a powerful shock that stops an assailant. Here, the shock is to scare and hurt but not to kill. Bad person may not be in position to control his body for few seconds after shock and at that time we can […]
