Well, As stated earlier, My goal is to design board such a that any DIY PCB etcher can do.
So, I gave special preference to net classes, by making all of them to 1 mm. [thicker traces are best in Iron based toner-transfer method]
I choose DipTrace PCB tool to design the board, It's really an easy tool to work with.
Speaking of placement, I followed K.I.S.S.[Keep it Smart & Simple] rule, and tried well for it.

LM317 being widely used regulator. It's circuit is straight forward and proven. It didn't take much time to put all the pieces together. And within no time I was ready with Schema.
5mm LEDs at the output end of each LM317, to indicate the ON/working status.
