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 […]
Light Up LED with Weak 1.5V Battery using Joule Thief Circuit
This easy LED circuit with Joule Thief can make light from a weak 1.5V battery, also it works with white, blue and UV LEDs. Further, we only need a low power battery like 1.2V, even better the LED still glows even if the battery is very low like 0.4V. So now we can use old […]
220V SMPS Circuit using One Transistor
To begin with, 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, it does not need a special IC or many extra parts, instead, it uses a special diode and a transformer coil, so it controls […]
5 Watt LED Driver Circuit (SMPS)
This 5 Watt LED Driver Circuit (SMPS) shows how to make power supply using wall plug to turn ON bright LEDs. Also, it supports white LEDs but it works with blue, green, red, yellow and even UV light What is a 5 Watt LED Driver Circuit: A 5 Watt LED Driver Circuit powers a 5-watt […]
