There's already some similar boards on Aliexpress that do this. I didn't look for an adjustable version, but the ones that only output 3.3/5 cost less than $1 shipped.

Thanks I will,  Check out my Prototype 3.  It has more bells and whistles.  This version is a simple non Micro controller version. Right now the cost of components is less than $4 in low quantity.
