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. […]

This 5 Watt LED Driver Circuit (SMPS) tell how to make power supply using wall plug to turn ON bright LEDs. It is made for white LEDs but also can work with blue, green, red, yellow, even UV light. What is a 5 Watt LED Driver Circuit: A 5 watt LED light is powered by […]
IC 555 Inverter Circuit
Need for some small power thing which always grow and mostly when no plug is in wall like in car, trailer or small house. Making our own DC to AC IC 555 Inverter Circuit is good idea. It can give power to many home stuff like radio, DVD player, electric shave machine and others. Circuit […]
SMPS Halogen Lamp Circuit
SMPS Halogen Lamp Circuit mostly need transformer for working. This post talk about new type transformer using switching power supply. It is more simple than older transformers and can work with other bulbs too if they do no use radio wave RF. This new design also save energy. What is a SMPS Halogen Lamp Circuit: […]
