Yes Sarma -- I'm sure there is some extra noise someplace due to using the switching regulator.?
On the other hand, I also gained an extra voltage display, which I love, and I got to solder a new board into the mix, which I love.
If I ever run on battery power, I will feel really smart for using a switching regulator and not a power hungry linear regulator. (actually, I may never do that, but just in case...I can say I planned ahead. Which is totally untrue, it just worked out that way.)
And as an extra bonus, nothing blew up -- which I also love.
