Hello I have need for a timer that would be used to turn a 12 v. beeper device on for one second or less and then off for 10- 30 seconds and then back to beeper , looked at a bunch of 555 IC circuits and hate to spend a day experimenting to get the right combo. , as an old HAM , I used to love the challenge , even looked at using a timed relay , most of the 555 circuits are 50/50 and that won't do , any ideas would be appreciated .
