Uh, well you have an idea what it feels like anyway. 
Nick, do you want to tak about this circuit or are you just fulfilling a mission to post it? It graphically potrays the concept at an acceptable level but it needs some help with the text and values shown. Iāll just leave it at that unless people want to talk more.
Yeah Nickā¦ What the heck are you doing?
JK 
Feel free to talk away as much as youād like.
I donāt intend to play with household AC anytime soon, but extra information never hurts.
AFAIK, the values there can be explained as follows:
.1A fuse because .1A * 14 = 1.4A DC output, which should be both safe and sufficient for most electronics needs.
14:1 ratio because it outputs high enough voltage to allow for the 7805ās dropout.
10uF and .1uF cap because those are the generic bulk filter and
And, I call it ābouncingā because thatās what the graph of the absolute value of a sin wave looks like.
Iām guessing that the transformer wonāt actually output the ideal 7.9VAC, but Iām not familiar with the efficiencies of transformers, so I donāt know how much that should be derated.
Howās that sound?
Hmm, I typed up sort of an analysis and info on how you go about designing a linear power supply like this but I am not sure if it is right to post it here in this thread. If you want to start a power supply thread somewhere with your diagram Iāll post the chunk of text I wrote for it.
