Macro-Lens Hardware Mod
Here's an interesting hardware mod: When Colin Devroe's digital camera broke, he had the foresight to keep it around for a while to see if could somehow be put to good use. Eventually it was; he dismantled it and created a macro lense for his iPhone that works surprisingly well. More after the break.
To construct the makeshift lens attachment, he took some double-sided tape and wrapped it around the lens, and then fastened it on to the iPhone with a paperclip. The results were impressive, especially for something like this. Click on the thumbs below to see his Flickr gallery.
