seagates5 Posted September 28, 2011 Share Posted September 28, 2011 I seen the write-up to DIY repair the needles, but I was wondering is there a way to hook up the LEDs in a series so that you dont have to use a resistor? If so, how many? Quote Link to comment Share on other sites More sharing options...
cduluk Posted October 1, 2011 Share Posted October 1, 2011 calculate input voltage, divide by how many LED's yields how much voltage for each LED. Every LED required voltage is different and should be indicated on the package. Quote Link to comment Share on other sites More sharing options...
