Not I. I am a paint by number when it comes to electronics. Someone else designs, provides assembly instructions of a working project, that I can follow, then I will build and hope that it works. Hope that I don't have bad solder joints, this has never happened, or put diodes in backwards, this has happened with my first HF rig kit from Heathkit. An Elmer checked my work, found the problem, corrected it and returned kit radio to me. I am an operator. I might be too old to grasp how to make the magic work. I have tried to learn for over 30 years but it doesn't stick in my brain cells. I am better at computer hardware and programming.
