Today I built the second iteration of my timing circuit. It turns out a problem I was having with my first circuit still exists with this circuit because that has to do with a misunderstanding of how the tactile switch I'm using works. I thought the big separation between two prongs meant that the two prongs on one side were connected,  but it turns out the long way is how they were connected. Not sure if that made sense but hopefully the attached photos will help.

This first working build was made by soldering jumper wires to the switch so that I could put them where they are supposed to go. 

I also had two capacitors malfunction on me and I am not sure why, but it could be because my soldering iron gets too hot.

Now I will go and fix up my schematic for my next order and take this as a lesson to triple-check components.
