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, dark room timer, memo-reminder or other similar ...

This simple LED driver circuit allows us to drive up to seven LEDs by using ... The LED driver uses a CMOS 555 timer since it operated with low voltages and can work for about 190 hours when using a ...

This voltage-booster circuit for driving one or more white ... where K is a constant that depends on the particular type of 555 timer used. The LED's peak current is roughly equal to the maximum ...

[FightCube] wrote in recommending a very helpful piece of circuit simulation software for those of you still constructing entries for the 555 design contest. LTSpiceIV, available from Linear ...

Frank’s LED dimming circuit is based on a 555 Timer chip. The fixture is only pulsed long enough with the 12 volts to establish the desired brightness level. This method overrides the “avalanche” ...

So he set out to replicate this hack with that most cherished of ICs, the 555 timer. In the video after the break, he demonstrates his “old-school” LED candle for anyone who thinks the only ...

The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters. However, another very popular IC, the LM386 audio amplifier ...
