A/D Envelope – Thomas Henry design layout by Eddy Bergman

This neat design works with a NE555 as well as with a 7555 IC – tested by me.

Waaaay to big but I had to learn a lot at this point – and still do. None the less it works 😀

How to make it better? Maybe add a looping stage with another opamp? Maybe an inverter circuit?
