The classic edition is the one that started it all.  I believe that a hackable bare-bones timer is perfect for some situations.

Features:

Reason Developed: I needed a way to economize the use of my water recirculating pump while ensuring I had hot water in the house.  I designed and built this circuit to run for 75 seconds and then wait for 450 seconds.  I wanted to be sure I could modify it in the future if the need arose.  I built this project after taking the Advanced Arduino course from TXRX Labs.  Credit for design review and constructive feedback goes to the great folks at TXRX Labs.
