On any given day at this site, one is likely to come across someone's version of the two transistor astable multivibrator Led flasher circuit. And they're all pretty much the same, because there isn't much room for variation. Yet they all seem to collect a lot of views. I don't however see anyone using the Segmented Astable Sequencing format. I twist and turn the layouts but all of my flasher circuits published here are based on this (simple but versatile) topology. Honestly I think it would be cool to see what someone else can dream up implementing this format.
In the interest of helping things along, I present these two variations that have a clear and straightforward layout, with the hope that some of you will learn how it works and design a flasher of your own. I'm not the jealous type so, go for it! I have fun designing mine and even learned a few things along the way. I hope you do too!..
