HOW TO Build a Helmet Light
It’s that time of year again…time to bust out the headlight for a midweek-after-work-night ride! But, in order to have a fun and safe nighttime mountain bike adventure you need one critical piece of equipment…a bright light to adorn your helmet and illuminate the trail ahead. The only dilemma is, a good light system can run between $200-$300 bucks. I don’t know about the rest of you, but that’s a little rich for my blood. That’s why last year I decided to take the MacGyver approach and build my own Link.
Is there anything the TI’s can’t do?…it’s not one of those slow and unplayable basic games. This is a real-time 3d-raycaster based on the game by id. Also includes an on-calc mapeditor. 
I really like this idea…I hate wrapping gifts. It’s the most unoriginal part of gift-giving. Although my gifts are hardly ever spectacular, my wrapping will always outshine them. I recommend using this wrapping method for giving out crowbars at Christmas. The extra irony makes the project that much sweeter. It’s really not your problem how to open the crate once the gift has been given, so don’t let anyone sucker you into opening it for them. 
I really like Firefox, mostly because you can make your own browser with all the GreaseMonkey stuff…and now check this- The Mozilla Foundation, developer of the Firefox Web browser, plans to announce Wednesday that it has created a for-profit subsidiary to pursue wider potential for the software.
