Hothead asks for help in naming its next game -- and we oblige!

If you see us walking around over the next few days, randomly shouting phrases like "Card Wizard" and "Spell Deck," we need you to know that we haven't completely lost our minds. We're just trying to come up with some helpful submissions for the name of Hothead's next game.

All we know about the game is that it features wizards, and also cards, as evidenced in the screenshot above. Here's a little inspirational fuel for your brain-fires -- let's see if you can top us, possibly ascending yourself to ludological superstardom in the process:
  • Card Carrying Wizard Club
  • Cardmaster's Quest: Eternal Mana War of the Deckwizards
  • Cards of Duty: Black Arts
  • Get Out of My Dreams, Get Into My Cards
  • Gin Runey
  • Go Fish (With an Enchanted Fishing Pole or Something, I Don't Know)
  • Guess Who: Portraits of Power
  • Hocus Poker
  • Middle Earth Hold 'Em
  • Protect Ya' Deck
  • Yu-Gi-Oh
Just drop your ideas in the comments of Hothead's post, and feel free to also share your cleverness with your fellow commenters below!

[Thanks Austin!]

Patti Smith Wins National Book Award [Winners]

Musician Patti Smith won the nonfiction National Book Award on Wednesday for her memoir Just Kids, while Jaimy Gordon's Lord of Misrule came out of nowhere (well, Kingston, N.Y.) to win the fiction prize. Everyone was very surprised! And drunk. More »

18' Canoe from single sheet of plywood

dug15.jpg

Check out this amazing 18' canoe made from a single sheet of plywood. Resembling a South American "pipante" dugout canoe, Finnish boat builder Hannu Vartiala designed and built his craft, "dug", in an attempt to correct balancing issues he had with a previous design. He's also put up instructions on his site so you can build your own. It sure is an impressive example of maximum use of materials with minimal effort. [via HackerNews]

How-To: Modded camera looks at Kinect infrared output

microsoftkinectIR_danreetz_2.jpg
microsoftkinectIR_danreetz_1.JPG

Scanner of books, winner of laser contests, and North Dakota maker Daniel Reetz has plans to turn his Microsoft Kinect into a scanner. His first step? Hack a Canon Powershot A540 to capture light in the infrared spectrum. Of course you can use an IR camera for lots of other fun things, but Dan's focusing on reverse-engineering the way Kinect uses a IR. The matrix of IR speckles above, captured close-up, is of particular interest.

Microsoft's new Kinect sensor is garnering a lot of attention from the hacking community, but the technical specifics of how it works still aren't clear. I am working to understand the technology at a fundamental level - my interest is in the optical side of Kinect. My ultimate goal is to make the sensor nearsighted, so that the depth resolution can be used to scan small objects. The first step in understanding a technology is to look at it -- that's why teardowns like this one at iFixit are so important.

Unfortunately for us humans the Kinect projector is infrared (or near-infrared) -- probably somewhere between 900 and 1020nm. My guess is that it's around 904nm, because it's cheap to produce those lasers, but that's just a guess; I haven't measured anything yet. That means that by design, we can't see the projection directly with our eyes. But we can see it with a camera. Almost all CMOS sensors in digital cameras ARE sensitive to infrared. In fact, they are so sensitive that there is a filter placed between the lens and the sensor to prevent IR from messing up your pictures. It's called the IR cutoff filter.

...

[The image above is] interesting in a few different ways. One can easily see that the Kinect IR speckle-field is a 3�3 matrix of random dots. One can also see that they are differentiated by intensity and have a centered registration dot. So it is not purely random speckle.

Human-powered cranes and lifting devices

tubular-crane.jpg

Gareth and I share an affection for Kris De Decker's Low-tech Magazine, which, per its masthead, "refuses to assume that every problem has a high-tech solution." Like its content, its style stands in refreshing contrast to the frenetic pace of the modern blogosphere: Low-tech updates only once or twice a month, and those updates are lengthy, well-written, well-illustrated, and carefully researched.

They just put up a great article about the machines people used to lift and move heavy loads before the advent of steam power. Arguably the pinnacle of human-powered lifting technology were Sir William Fairbairn's hand-cranked "Tubular Cranes," one of which is shown above as illustrated in Fairbairn's 1860 Useful Information for Engineers, Vol. 2:

Hence the advantage gained by the gearing will be W/P = 18 x 63.75 x 80 / 6 x 8 x 12 = 158 or taking the number of cogs in each wheel W/P = 18 x 95 x 100 / 12 x 9 x 10 = 158 and as this result is quadrupled by the fixed and moveable pulleys, the power of the men applied to the handles is multiplied 632 times by the gearing and blocks. Two men are sufficient to move round the crane with 60 tonnes suspended from the extreme point of the jib.

Check out the whole article here.

Trumer Beer Rube Goldberg machine

The Brookstone Beer Bulletin tipped us off to the fact that brewer Trumer Brauerei of Berkeley, CA, has created a fun video featuring a Rube Goldberg device made from Trumer product and paraphernalia.

The Trume Pils Rube Goldberg Machine! Inspired by the Rube-Goldberg-Machine we were able to recreate the brewing process in a new way. Just as the video focuses on fine tuning, we also take the smallest details in mind when brewing our beer! Prost.

Fun!

4 Memberships Worth the Cost

When the money gets tight and I'm trying to plug the leaks in my budget to save money where I can. This means memberships and subscriptions are the first to determine if they should stay or go.

I have had a club membership to one of the warehouse stores for the last 4 years. Every year it comes up for renewal, I decide if it is worth having for another year. Obviously that answer has been yes the last 3 years. But for some people, the extra money for a membership isn't worth it.

Warehouse Stores
Going into large box stores gives me a headache and tires my feet out at the thought. But I still go because I can buy paper products and frozen food, then not have to worry about buying them again for 6-12 months. To me, this savings is worth the membership and the savings in time. 

Consumer Report used mystery shoppers on warehouse club savings and found that they shaved 25-55% off the cost of the items. The only area they didn't save was on drinks. This is one way to save money if coupons are not used.

Gym Memberships
In my area, a membership to a 24 hour fitness center is cheaper by 15-20 dollars than the Y, and it's closer. But that may vary by regions. If working out in a pool or in a class is more supportive for staying healthy, I can see how buying a gym membership is better than any of 37 frugal approaches to fitness. I also want to make sure I get my shower done at the gym for the water and heat savings.

Pandora Music
This is one membership I don't think twice about renewing. For $3 a month I get tons of music that I LOVE, without commercials. I realize there are other free alternatives, but they come with commercials, kick off frequently and are not as mobile. I use the Pandora App as well. Overall, this keeps me sane while at work and helps me focus when home - all worth the price for me.

I would say that I listen to Pandora about 30 hours a week and I have multiple stations setup depending on my mood. This much listening puts me way over the 40hr/mo. limit for the free option. They also have cool kid's stations as well - not that I will have need for this.

Credit Unions
I paid $25 once to become a member of my local credit union. It has been well worth the money. When I bought a car and had it financed through the dealership, I later refinanced through the credit union and saved a few thousand dollars off the life of the loan and lowered my monthly payments so I could pay it off earlier.

I also have saved money with a credit union by not paying big bank fees on minimums and I know they are looking out to save me money and not make a huge profit for board members and shareholders.

What memberships do you subscribe to that are worthwhile? 
What is the cost?
What is the savings you receive?
