How to Build a Two LED Temperature Indicator Circuit
This article shows how to build a Two LED Temperature Indicator Circuit, as it is easy and cool project and we can use this circuit for many things, like checking water shower when it is not too hot, so no damage can happen. Furthermore, also be sure computer parts, amplifier, heater and even car water […]
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 […]
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 […]
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 […]
