Hi, I just thought I provide a backup mirror of this nifty tool.
The original source of this tool has been gone for several month now, and there seems to be no other mirror. Luckily I still had a copy on my hard drive.
It's comes in handy when you want to calculate a specific resistor value which you don't have in your inventory.

Anyway here is the download link:'

All credit for this tool go to the original author.
Cheers,
