Short post, covering a few topics...
Let's see... Am going to list a couple of more projects that I'm working on...
1. Speakjet based text-to-speech reader. I'm using a Etherten Arduino board, primarily because it has a micro-SD slot, which will go into the Speakjet via the matching dictionary chip. The idea being to be able to download text files from, for example, Project Gutenburg, and have the board read them aloud. Obviously, this isn't going to be as good as a properly produced audio book, or even the best quality text-to-speech programs, but it's an easy enough project...
2. Electronic binoculars. Or rather, monocular. Okay, I'm a Star Wars freak - I'm building my own astromech, after all. But these aren't that difficult to do, really... Will start off with a 3 axis accelerometer, outputting to a video overlay processor, on top of a camera signal. Can then add magnetometer, gps, etc., info. The hard parts will be range finding, autofocus... and making my own zoom lens.
3. Have ordered legs and feet for my droid! Now just waiting...
