While it certainly isn't a crime to send a private message, it is most certainly not my preferred method of providing assistance here.Hi, i think i've committed no crime sending this mail(prvt) to u.
I have a project i got from an old text bk and i feel that i shd try it(called "hypnotic sound generator").ie to replace LM 3909 with 555timer.But the problem is the pinouts.
Kindly i would request if u would send me u'r email so that i can send the pinouts 4 u for easier reply.I didn't want to post in the forums coz it has been asked many times ,i being one of them.My email is
(omitted to protect MIRINGU's privacy)
Thanks n have nice time
Communicating via PM completely excludes anyone else from benefitting from the exchange, effectively defeating the purpose of the Board.
PM exchanges also eliminate the possibility that you may benefit from other informed responses.
I don't give out my E-mail address, because I would be inundated with requests. I simply cannot let that happen.
As far as your circuit is concerned, the LM3909 is very different from the various versions of 555 timers. It can operate normally on voltages far below the requirements of a 555.
If you wish to replicate the function of an LM3909, here is a page that describes how to build one out of discrete components:

If you are insistent on using a 555 timer, you will need to use a completely different circuit.
Post your circuit so that we can see what you are attempting to do.
