Here's a weather instrument - the Dodecahedral Barometer - that can actually determine how tall you are by reading the barometric pressure between your head and your feet. Mark Thoren notes that his gadget was inspired by the release of some new electronic products. The first is a Serta model 270 barometric pressure sensor that recently came on the market. The sensor is inexpensive and accurate to the point of being suitable for weather stations. The other items that make this gadget possible are some new HP displays that make the gadget's readings visually appealing.
