LED Chaser Circuits: 10 LED Running Light Designs Discussed
In this article I have compiled 10 interesting yet simple LED chaser circuits, which not only create beautiful running light effect but are also easy to build. These primarily incorporate LEDs as well as mains operated bulbs through triacs. The proposed circuit is transformerless and is thus a lot compact and light weight. Which LED […]
Bicycle LED Light Circuit Using a Single 1.5V Cell
The proposed bike flasher flashes two white LEDs from a single 1.5V cell by using a solitary general purpose transistor, and does not need core for the involved transformer, the main core being the Air itself. Using Joule Thief Concept Every Joule Thief circuit uses ferrite rod or toroid core and its turns are wounded […]
