If you're in an electronic time warp that's stuck in 2001 (like me) and use the free cell phone that came with your sign-on agreement, you can still use all the woodworking-related utilities that Kenneth Woodruff and Marc Spagnuolo ha

Included in the features are: a board foot calculator; decimal to fraction conversions; wood movement calculations; shellac to alcohol proportions; squareness calculations; and lots of tips and links from Marc, The Wood Whisperer.
The wood movement chart is particularly amazing. Have you been wondering just how much a riftsawn board of Albizia will move in 50% humidity at 80ยบ? Check the chart; it's there.
Kenneth and Marc plan to add more resources to The Woodshop Widget, but already it has enough useful tools to help us in our own woodshops.
