audioguru Posted April 23, 2011 Report Share Posted April 23, 2011 I don't believe it.Two series connected LEDs in my project http://www.electronics-lab.com/projects/motor_light/002/index.html don't work anymore. They are the second-lowest ones so they have been turned on most of the time at about 25mA for nearly 6 years.I thought the LM3915 driver IC had failed but no, one LED is now open.It is an American Name-Brand LED, not a cheap one from China.Luckily I have a bag full of them.The replaced LED works perfectly.

audioguru Posted March 4, 2013 Author Report Share Posted March 4, 2013 I am trying to make your project for part of my electronic course at college and I was wondering if you have any electronic versions of the informationI designed and made only one circuit over 7 years ago. It still works fine.My computer and digital camera were brand new and I was still learning how to use them.Here is the parts layout photo with red "Xs" where each stripboard track was cut and this photo has better contrast.
