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 […]
IC 555 Inverter Circuit
Need for small power things is always growing, mostly when no plug is in wall like in car, trailer or small house. So making our own DC to AC IC 555 Inverter Circuit is good idea and it easy to build. Also, it can give power to many home stuff like radio, DVD player, electric […]
SMPS Halogen Lamp Circuit
An SMPS halogen lamp circuit mostly needs a transformer to work and in this post we explain a new type of transformer using a switching power supply. Also, the circuit is simpler than old transformers and it can work with other bulbs too but only if they do not use RF (radio waves), furthermore, this […]
Simple ON-OFF Touch Switch Circuit with Relay
This is an easy circuit for Simple ON-OFF Touch Switch Circuit with Relay, where we touch one time and it turn ON and touch again it will turn OFF. Furthermore, this circuit is good to control light, fan or other electronic device, where there is no need of expensive or hard parts, also there is […]
