LED Testor
OK it's Official, I have WAY too much time on my hands in the winter time.
I had taken out my old lights to inspect them, test them, and upgrade them. I also had a few stray LED's which I couldn't identify the colors. Holding a resistor while checking these things was a pain. So I made this little contraption using a 12V wall wart, some heavy gauge copper wire, a micro-LED (resistorized), and a spare 580 ohm resistor.
On the left is straight 12V to test finished lights and other 12V items (small Motors?). On the Right is a resistor with high enough value to test most Single and multiple NON-resistorized LED's without any damage. I added the small LED in the front so I would know when the contraption was live (plugged in).
For more complex LED patterns, I have some spare alligator clips (and wire) to test those arrays before they are fully completed.
I NEED to get a LIFE!
It works GREAT though, and would have helped a lot in my LED build.
