Thanks Fraley1701!   One thing though, this list is actually missing four videos!  I will put them at the end of this post.   They are videos about the 555 timer chip.

ShutterAce:  No that app will not replace a breadboard.  I have used it for checking the value of a resistor when I don't want to look up the color codes.   I have also used it to check pin outs and to calculate resistance when working with LED's.  

But I am going to stick to the bread board when building up circuits and trying to set timing rates.   If you check the 555 timer calculator, that circuit doesn't look like the one I am using in my videos.  I am pretty sure that it is giving the right blink rate and that it will match what I see in my circuit.  I just think it will be more satisfactory to get out a variable resistor and just dial in the blink rate I want.

Here are the missing videos:
