Am working with strings of leds, yellow and red. useing a power supply that I built useing a 317T voltage regulator. My problem is when I turn up the voltage to light up the yellow it literally smokes the red leds. My problem is that I need to build a dual voltage power supply, and I need to know what type of mini pot (5k) (as Digi-key shows a gazillion types) to use. Thanks
