This college paper (lab report) is in french for now (April 7th 2012), I’ll translate it as soon as I find some time.
It’s pretty much detailed, 11 pages talking about monostable and astable modes, with schematics, and ways to tweak the duty cycle. (making an astable with 50% duty cycle), reducing and eliminating the recovery time in monostable mode, etc…
