Some of you may have noticed that I've been collecting links to worthy "How to" and DIY resources over there on the sidebar. Well I just found one that warrants a post!
http://www.instructables.com/ lets folks post step by step instructions complete with photos of how to do any number of things. It seems to be mostly building stuff, but I did see a how to make pesto page.
Interestingly enough, I found instructions on how to make a
marshmellow gun. My father-in-law is an expert crafter of these. Notice in all the photos the use of proper eye protection!
When you feel yourself craving more power you might want to step it up to this
potato cannon.
There is a pretty good variety of content. Lots of bicycle mods, and low budget photography tips like how to make a light box.
