I recently bought a string of 50 individually addressable RGB LEDs from Embedded Adventures and so had to decide what to do with them. I decided it would be festive if they could reflect Twitter’s current feeling about Christmas. So I started Googling sentiment analysis and quickly discovered that Stanford University’s Natural Language Processing Group has released the source and data for their sentiment analyser. When fed a sentence it outputs one of “Very negative”, “Negative”, “Neutral”, “Positive” or “Very positive”.

TwitBeeb Photo by John Honniball TwitBeeb is a BBC B microcomputer (vintage 1981) from which you can Tweet. The Beeb itself was my main computer until 1994, I taught myself to program on it. A few years ago I pulled a rather scuffed up BBC out of a skip at Sussex University and took it home. Inside it had an add-on ROM board with several programs in ROM chips including a serial terminal emulator called Termulator.
