Those who know me know that I've always got some project on the go at all times. My interests are varied enough that I can jump from one to the next and not get bored. I seem to learn by doing and the best way to learn something is to start a project utilizing it.
I've also just started a blog related to photography, it will have DIY stuff as well as tips & tricks etc. http://www.jph-photography.blogspot.com
