Jeez! I love you guys! How could we survive without a forum like this? I will make the mods and look up that current device. Simple is already better. I do have some other resistors to try. Maybe that's why the light wasn't as bright as it could be. BTW: is there any reason why the resistor calc shows the current limiting resistor on the negative side of the LED? Does it make any difference which side it's on in a series circuit?

Grabski's schematic is 17 years old. Perhaps an newer design needs to be offered, and I think Gunner has done that.
