This page presents general information and tips for using the LM555 timer and devices with other letter prefixes. There will be minor internal circuitry differences between 555 timer IC's from the various manufacturers but they all should be useable for the circuits on this page. If you would like to use any of these ideas, take the time to do some testing before using the LM555 timer in an actual circuit. All of the solutions on this page can also be applied to the LM556 - Dual timer. Some of the circuits on this page were developed just to see if they would work and have no intended use. The menu below links to various sections of this page that relate to the items in the index.
LM555 Timer Circuits
This circuit is how [John Tsiombikas] makes his cheap 3D shutter glasses work with a Linux machine . It’s not that they were incompatible with Linux. The issue is that only certain video cards have the stereo port necessary to drive the head-mounted hardware. Shutter glasses block light from one eye at a time, so that different renderings can be shown to create the stereoscopic effect. Since stimulating the muscles in the eye doesn’t actually work , you need to find a way to drive the glasses in perfect time with the video signal. His circuit watches for the V-Sync signal, then uses it to toggle the shutter glasses.

This member of the MAKE Flickr pool added a 555 light-flashing circuit (from Charles Platt’s “The Biggest Little Chip” piece in MAKE, Volume 10) to the cover of his Maker’s Notebook.
