Yes I have. It works as designed.
The LED should only come on if the voltage on the base of Q1 is below appx .6 volts.
I solder mine on prefer board now have hard time trouble shooting.
Do you use breadboard? If you do then can you share link what kind and where I get it? If not then what do you ise and share where I can get that?
