If you are into building your own gadgets and fool around with technology and have not been in San Mateo last weekend, you missed out on the Maker Faire by MAKE magazine.
Good thing Engadget was there and has published coverage part 1 and coverage part 2 of the event.
More photos of the DIY fair are on Flickr. Back when I was in my teens I tried to build electronic gadgets myself. I just was not really good at it. Now I prefer to buy or have companies send me their products for review.
