The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

LED flasher circuit 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 ...

This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, ...

Of course, [Eric Wasatonic] didn’t come up with this idea (he links to this Simple LED Flasher Circuit page in the description of the video) but [Eric] shows us the process he took discovering ...

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.

Installing the LED Turn Signals To make it easier, place the clear lens over the front of the circuit board first before you insert the Phillips head screw to reinstall the turn signal, because it ...

If there is an incandescent bulb somewhere in the circuit that you are trying to flash, a standard flasher unit may work on rare occasions. The fix for this problem is installing a "no load" LED ...

Do you flick on your turn signal and hear one — or even both of your blinkers — tick faster than usual? This isn't some new gimmick with your car. It indicates that there's an electrical issue ...

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well. Current through component and voltages on nodes can be ...

In Figure 1, National Semiconductor's LM3710, a supervisory circuit, is configured to reduce the power consumption of a traditional LED indicator by 99%.
