I have one and it works great! Haven't noticed any noise. Crimped on power poles on the input and soldered a barrel connector on the output. Thinking about adding an output for the USB hub next but that's a project for another day.  

Good luck and 73,

If you get one lets us know how it works for you. I will put a link on the web page as I am sure this would be of interest to even fixed station nodes for running the BBB from a single 12V supply.
