The post narrates how a single chip MAX641 can be used for making an efficient 3V to 5V boost converter circuit for charging 5V battery from a 3V source for illuminating power LEDs from a 3V source. A quick glance at the electronic market lets us to see that practically everything in electronics are accessible […]
LED Projects
LED Amplifier Circuit
The light emission of an LED is usually fairly small. In case a lot more brightness is needed, the following LED amplifier circuit might help. The LED to be amplified’ is actually substituted by an LED in an opto-coupler that clicks a lamp (for instance, a signal lamp) attached to the mains supply. Once the […]
Simplest Strobe Light Circuit
A very simple strobe light circuit can be built using a single transistor and a high bright white LED, in conjunction with a flickering LED. As may be seen in the diagram, a simple single transistor driver is used for illuminating the strobe LED lamp, which is controlled by a self oscillating flickering LED connected […]
Car Chasing LED Arrow Turn Signal Indicator Circuit
A very simple yet interesting Chasing LED arrow car tun signal indicator circuit is discussed in this article. The circuit uses just a single 10 stage Johnson’s decade counter IC 4017 and an UJT for executing a very interesting two pattern LED light chasing on the connected LEDs, which produce an impression of creating an […]
Simple High Power LED Flashlight Circuit
Making a high power LED flashlight circuit is simple. All you need is to gather the components and follow instruction to build the system. This article has explained in detail [along with diagrams] the procedure to make a LED Flashlight: Recommended Components 24 Super-bright LEDs 3 batteries [AA] Resistor to manage current flow Procedure of […]
Simple 1 Watt LED Driver Circuit
Here is an illustration of this efficiently operating a Simple 1 Watt LED Driver Circuit from a 12 volt battery power implementing a buck converter. The LED may perhaps plainly be tied to a series resistor to achieve the expected current, but then the efficiency could well be barely 25% because the resistor could possibly […]
