Hey, all! Thanks for entering the contest, but as they say: many will enter, few will win. In this case only one: James, who “Did my first backflip snowboarding off a 20 foot cliff, luckily it was all powder I landed in, because i landed pretty much on my head, and my friends had to dig me out of the three feet of powder. It was great.” Watch your email, James.

My random number generator actually put me on a non-extreme one so I rolled up and my mouse landed on this lucky guy. Thing is, he’s not responding to my emails. Consider this public warning, James! Get back to me or tomorrow I’ll have to pick another winner! I’d like this thing to be in someone’s hands by Christmas. Thanks for getting back to me, James! Congrats!

Be sure to keep an eye out for our other giveaways, there’s lots more stuff to be won this holiday season!

You like music, right? How about CDs? Do you still have CDs? Don’t have any cash this week? Did you spend a lot of money on presents for the kids already? Do you want one of these Olive No 4 Hi-Fi? Am I asking too many questions? Yes? No?

Well today we have one of the coolest prizes to come over the transom in a while. It’s the Olive No 4 Hi-Fi. How do you win? You need to convince us your current music system sucks in comments. We’ll pick the saddest of the sad sacks. Extra points if you include a link to an image of your sad, sad stereo.

Here are some specs:

–Storage capacity of up to 1,500 CDs in hi-fi digital instantly gets rid of CD clutter and ensures crystal clear sound quality

–Full-color touchscreen display makes it easy for users to find the music they want

–Multi-room music streaming and the ability to import music from a computer (wired or wireless) allow easy access to all your digital music sources in every room of your home

–Seamless integration with existing hi-fi systems and a high resolution DAC deliver the best possible hi-fi audio experience (unlike any MP3 player)

–Fine-grade aluminum and distinctive graphics provide an elegant design

Roll out the comments and we’ll pick a winner on Friday.

Did you see my review of the ContourHD 1080p? Well, go check it out so you know whether or not you can make use of this sucker. It’s basically a compact HD camcorder stripped of everything but the lens, sensor, and storage, stuck inside a tiny, semi-rugged aluminum case. It’s for sticking to your helmet or bike frame and documenting all that extreme stuff you do. And we want to give one to you.

All you’ve got to do is tell us something extreme you’ve done lately in the comments. It could be anything. TechCrunch readers, that could be flaming Mike, or being first to put an anti-iPhone comment on one of MG’s posts. CG readers, you might have soldered something lately, or talked to a girl. Personally, my most extreme event recently is very nearly slipping on some ice. That was close!

Seriously though, just put something awesome in there, be it wingsuit-diving or a sweet headshot in Modern Warfare 2. I’ll pick a winner semi-randomly (non-extreme entries will be skipped) in three days and we’ll try to get it out to you before Christmas.

Boobledee ooh ooh woo woo ha lala! We’re coming at you with a fancy Monster Miles Davis Headphone pack. The kit includes Monster Miles Davis Tribute Jazz In-Ear Headphones, three albums, and a sassy print.

Take the A train past the jump to figure out how to win.

- Monster Miles Davis Tribute Jazz In-Ear Headphones ($499.99 retail value).
-Three (3) Album CDs from the Miles Davis: The Complete Columbia Album Collection box set.
-One (1) Miles Davis branded and fully loaded USB.
-One (1) Miles Davis print from ICON Collectibles.

All you’ve got to do is comment. We’ll pick a winner on Tuesday.

Finally. We’re done. All you have to do is comment on this post and, presumably, all the other posts in this series, and then you’ll be eligible to win a SMART Board for your home, office, or school.

Sorry for making you guys jump through so many hoops but I thought this would be a good idea to make it a little harder to win a nice, classy prize like this.

Here’s some info:

Experience interactivity like never before with the SMART Board 685ix interactive whiteboard system. As the world’s first ultra-short throw interactive whiteboard system, the 685ix combines an ultra-short-throw projector with a widescreen interactive whiteboard. The 685ix offers you unparalleled image quality, a precise touch experience and a large interactive surface for teaching and learning.

The system’s ultra-short-throw projector, the UX60, virtually eliminates shadows, glare and distracting projector light. It is positioned directly above the interactive whiteboard, projecting crisp, bright images from only 12″ (30.5 cm) away. And because the 685ix’s interactive whiteboard is widescreen, it has 20% more working space than a standard board.

Good luck. I’ll pick a winner this weekend.

Sure, all the cool kids are ditching cable and satellite these days, but us normal folk still pay for our TV. If that’s you, then you need a DVR and Arris wants you to have a brand new Moxi HD DVR this holiday season. And yup, you get the new triple-tuner model that allows you to record three cable stations at once. The Moxi HD DVR doesn’t have any subscription costs, can record up to 75 hours of HD, and is packed full of features. You’ll love it, but you have to win it first.

You should know the drill by now. Leave a comment below describing your first TV and we’ll pick the winner at random on 12/18/2009. The winner must have a US shipping address. This DVR only works with cable systems so satellite subscribers and antenna users need not play. Good luck!

Of course if you don’t win, you could always swing over to Moxi.com and pick up a dual tuner model for $499 or the triple-tuner model with a Moxi Mate for $799. Just saying.
