This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Some 1.5 v LED flasher circuits are available on the internet and we like to present you four of them. The flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper uses ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...

A little modern technology can be good for old cars, but you've got to know how to integrate and use it properly. That's a lesson we learned recently when we replaced the standard-issue 1157 taillight ...

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well. Note, there is a flasher version 3 Current through component ...

They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a flashing LED was something of ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...
