Let's get a list going of everyone's favorite bookmarks. Could be blogs your check often, or resources you turn to when the magic smoke monster appears. I think it would be nice to not only give a URL, but a short description.
Some of mine:
http://dangerousprototypes.com/ - This site is full of yummy projects, tips, and how-to's. Very OSHW related stuff, mixed with app notes, and good tutorials.
http://tronixstuff.wordpress.com/ - tons of tutorials (46 arduino tutorial and counting) - and lost of other cool stuff
http://www.afrotechmods.com/ - I think this might just be Dave's American long lost brother. Some good, very basic videos and stuff for the noob - with a bit of attitude.
http://www.eevblog.com/ - some kiwi that has made dropping multimeters into a hobby.
(kidding - love ya dave!)
Hackaday.com - where I usually start my morning, only to shake my head at the comments.
(I'll leave out the company I work for - but I'm sure it will get mentioned)
Your turn!
