IC 555 Timer books

Could anyone point me in the direction of a second hand copy of a practical circuits or practical applications or circuits book for the 555 timer IC? Being a pensioner in difficult straights, and unable to get the help I need, I would like to resort to a book of practical 555 timer projects in order to get my project out of the way. Can anyone help me out here, please? Walt.

I think you can find free good matherial (schematic drawing, hints) in the web.
Try search "555 & timer & (schematic | diagram)" on a search motor.

Rizzo is right , search the web. the 555 timer is a very commom part of many homebrew and proffesional applications.
The phrase " Application Notes" is also usefull, if you get stuck come back here , someone will help.

Heres a link to one of the best 555 timer sites ive seen. If you have a printer/copier just print the whole thing out and then read it at your leisure.

Or try this,
