In this article I have explained an innovative way of driving more than a hundred white LEDs from a 6 volt battery. The circuit utilizes the IC 555 for driving a step up transformer, whose output is finally used for illuminating the LEDs. A special PWM configuration makes the circuit much power efficient. Main Stages […]

LED Chaser Circuit using IC 74LS164: LEDs illuminate in Bar Mode then Shut off together or one by one
This circuit is actually a little more advanced LED chaser scanner circuit using two 74LS164 Shift Register ICs together with one NE555 Timer, and yep the light effect looks somewhat similar to those old Knight Rider or Mustang scanner lights which move from sides toward center. The LEDs are arranged in two strips, or sometimes […]
How to Illuminate 1 Watt LEDs with Cell Phone Charger
Nowadays probably all of us have a spare cell phone charger lying idle in our cupboards or table drawers……so wouldn’t it be a great idea if we could employ it like a super bright 1 watt LED driver and illuminate our room with white cool moon light. Circuit Concept As we all know that a 1 watt […]
