John, thanks so much for this tutorial. I have picked up a few pointers needed to try this project. Your instructions are easy to follow for us neophytes. Any other neat projects will be appreciated.
Edit-please post relationship of ohms and voltage. E.g., if one used a 6 volt/50 mA transformer would one use a 280 resister (if there is such a thing)?
