Vendor's Description:
I bought this great Power Supply Kit by Chaney Electronics from The Electronic Goldmine.
It is rated for 0-12V. My kids managed to pull mine off the table and smashed the 500 ohm potentiometer. I wound up replacing it with a 1k ohm pot I had handy. I find I can get up to 15V from the supply with no problem for light loads.
I like re-using enclosures and parts from broken or old stuff. I used the case from an old coffee grinder that died.
I added the terminals, which I had on hand.
I also added the LED, switch and knob seen below.
I've bought some parts to add an LED bar graph to give me a rough idea of the output voltage, so I don't always need my multimeter to check it.

Panel Meters need power
I looked at includnig an LCD panel meter, but of course they all need their own power source and I didn' want to add a new regulator just to have a meter.
An analog panel meter could work, but finding one the right size, range and price proved to be a challenge.
