5 Easy 1 Watt LED Driver Circuits
In this post I have explained about a few easy to build, compact 1 watt LED bulb circuits. The first circuit is SMPS based, the second design uses a capacitive power supply, while the remaining concepts show how to used a DC source to illuminate a 1 watt LED. Warning: Many of the circuits I […]
How to Make a Simple 12 Volt LED Lantern Circuit
In this post I have explained how to build a simple 12V LED lantern circuit which may be used at night while travelling and outings such as in picnics, trekking, or camping etc. Introduction So far we have discussed white LEDs comprehensively through many of my earlier articles and have learned how efficient these lights […]
How to Make Any Light a Strobe Light Using Just Two Transistors
If you feel strobe lights very interesting but are disappointed by the fact that these wonderful light effects can be produced only through complex xenon tube then probably you are quite mistaken. It is very much possible to make any light a strobe light if you are equipped with a proper driving circuit capable of […]
3 Glittering LED Christmas Tree Light Circuits Explored
In this post we present 3 circuit ideas for creating beautiful Christmas tree light decorations. The first idea explains a transistorized flashing blinking LED string light which can be mounted on a Christmas tree. The second circuit diagram describes an LED light effect generator which can be also installed over a real Christmas tree for […]
