About Steam Engine

In , I got into rebuilding. I was searched for an online coil wrapping calculator, but all I could find was spreadsheets and Ohm's law calculators. So I created this site.

The tool was initially called vape calc due to a lack of imagination. Within the first month, the name was changed to Steam Engine.

Author of bugs and glitches

The Steam Engine is built and stoked by a Norwegian vaping code monkey.

Thanks to Ben Davis for designing the logo.

Safety – please vape responsibly

There are some dangers to Litihum ion batteries. The same goes for nicotine. Please inform yourself on battery safety and nicotine safety before you dive into rebuilding and DIY.

After you have made a coil, always measure the resistance before you use it. Also be conscious about the limitations of your batteries. Double check your calculations using different tools.

Concentrated nicotine can be lethal. Take the necessary precautions, and again, double check your calculations using other tools.
