This tutorial demonstrates how to connect the Adafruit MAX31855 Thermocouple Amplifier breakout board to the Electric Imp using SPI, as well as how to set up a Xively developer account and a Twitter application. You will log and graph temperature data on Xively, and tweet it to your own Twitter account.
Have a lackluster datasheet for your sensor, but a demo app from the vendor that seems to calculate the value you need? If the app is written in .Net (Visual Basic or C#) -- and if it's Windows based, it probably is -- you might be able to decompile the app and find that magic formula you're looking for!
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! We spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between. Now this lovely black deck works like any other USB keyboard. Sure it weighs more than our Macbook, but its worth it!
