In 2007 I moved my blog from my own bespoke CMS into Drupal. Back then, Drupal 6 was the state of the art and so that's what I used.
Drupal 7 came out just under two years ago, but for many and varied reasons there was a significant lag before contributed modules were updated to work with the newer Drupal core. I happily kept working mainly with Drupal 6 until I got a job developing new sites using Drupal 7 at the start of this year.
I was reminded the other day that if you want to do planetary astrophotography, hacking up a webcam is a cheap and easy way to computerise image capture. Better still, software exists to process videof rames into a single higher quality still image.
A spot of researching which webcams are best suited for this found a page explaining how to hack a Logictech Webcam Pro 9000. Better still, my corner discount computer parts shop actually still stocks these for all of $35 a piece.
