DIY Dreidel Made Out of Everyday Supplies

Easy-Spin-Top-Dreidle.jpg

Can it be Hanukkah time again already!? And here you are without your dreidel! But by now, the stores are probably picked dry of the best dreidels. What are you to do!?

Luckily, one patchwork artisan has the perfect stop-gap solution. All you need are four of those mini plastic key chain cards and a pen cap. You start by piercing the cards with the pen cap through the little holes in the corner. The cards should stay on by themselves. Spread them equally apart and you should have a balanced spinning device.

Now, what the original post doesn’t show is how to turn this spinner into a functioning dreidel. To do that, simply mark each card with one of the four Hebrew characters:  Nun, Gimel, Hei, and Shin (if you’re a little rusty on your Hebrew, check here). And now, the dreideling can commence and Hanukkah is saved! 

For those of you who need a refresher course on how to play dreidel, the simple rules can be found here. And for those of you who feel the need to turn everything into a drinking game, we’ve included some video instructions on that after the jump.

Ice Touchscreen Brings Modern Tech to Penguins, Santa (Video)

walloficedisplay-0.jpg

As the concept of physical controls become ever more dodo-ish, we see digital interfaces on just about everything. Even our solid forms of water aren’t safe.

A group of Finnish researchers who were able to build a touch screen out of a block of solid ice.

This very cool (get it?) touchscreen was assembled at the Nokia Research Center in Tampere, Finland.

The team used a set of infrared emitters and detectors to determine hand location on the wall of ice. The data was then collected and sent to a computer which projected images through the back of the semi-translucent block, creating an interactive surface.

Totems: Bottle Bike


You’d be surprised how much you can carry on a bike, and I don’t just mean the site of a huge beer belly shaking over the front wheel of a Berlin commuter bike. Some bikes are made to carry a load, whether it’s the famous Worksman of New York, or the bright-yellow machines ridden by German postal workers in Berlin (again).

But the best cargo bikes are those that have been hacked to achieve a specific load-carrying task. And that’s what you’ll see in this gallery of great cargo-bike mods.

Bottle-Carrier Bike

Photographer Alain Delorme loves crazy Chinese cyclists so much, he put together a whole project documenting the insanely overloaded cargo bikes in Shanghai. The images look to have had a certain amount of photoshopping applied, but if you have ever visited China, you’ll know that these precarious precipices are real enough.

Neato XV-11 robot vacuum gets its very own open source LIDAR hack

There’s nothing like a little bounty to light a fire under a group of open source fanatics, is there? We saw this principle applied recently when Adafruit offered up cold, hard cash for an Open Source Kinect driver, and now one enterprising reader over at robotbox.net has gone and hacked the LIDAR unit on a Neato XV-11 robot vacuum — and won $401 for the effort. What’s this mean to you? Well, the gentleman (who goes by the nom de hack Hash79) can now read data sent from the optical ranging hardware on the vacuum to a PC. There has been a pretty enthusiastic group of hackers surrounding the device for a while now and now with a little hard work (and a $399 autonomous robot vacuum) you too can have a 360 degree scanning LIDAR with one degree accuracy and a 10Hz refresh rate. Pretty sweet, right? Video after the break.

Dockstar FreeAgent hacked into inexpensive emulation masterpiece (video)

Hello, multipurpose! Seagate’s Pogoplug-based FreeAgent DockStar — at least at a glance — isn’t much good to those who aren’t buying up DockStar HDDs. But if you dig a little deeper, you’ll realize that this minuscule adapter packs a 1.2GHz Marvell processor, 128MB of RAM and 256MB of ROM. There’s also a smattering of USB ports and an Ethernet socket; add that all up, and you’ve got a hacker’s playground. One Hunter Davis decided to see just how much he could squeeze out of this here peripheral, which can be widely found for as little as $25 nowadays. Thanks to a copy of Debian Linux, a good bit of programming know-how, a DisplayLink USB-to-VGA adapter and a USB sound adapter, he was able to concoct a homegrown emulation console that could handle nearly everything he threw at it. ‘Course, you’ll have to spring for those other parts if you don’t have a house full of random doodads, but once he figures out how to install a battery and make the entire setup portable… look out! Head on past the break for an in-action video.

5 Things to Know Before Buying a Cordless Power Tool [Homemod]

There’s no better way to say “Merry Christmas, dear friend” than with a double-bevel compound miter saw or a heavy-duty 18V impact driver. But before you pick up a cordless tool for that special someone, keep these five things in mind. More »

Have a Very Slayer Christmas

It’s that time of year again! The colorful lights go up, the snow comes down, and there’s a bit of that indescribable magic in the air. Like most people, the first thing that comes to mind when I think of Christmas is, of course, Slayer. Yes, even that most evil of thrash bands can’t help but get into the season’s spirit of giving and brotherhood.

That’s why one enterprising lad has created this choreographed Christmas light extravaganza to the soundtrack of the classic holiday diddy “Raining Blood.”

This blast of yuletide fury was from 2009, and creator lacycute20 (who posted the video to his daughter’s YouTube account, so there’s lots of Justin Bieber and Ke$ha videos sharing space on the account) promises to have an all new choreography up for this year.

But for now, enjoy the Christmas wrath.

Adafruit Propeller Platform USB entices DIY electronics builders, ‘Gadget Gangsters’ at large

It’s days like today where you realize just how badly you need to scratch that DIY itch, and Adafruit‘s newest two circuit boards couldn’t be landing at a more opportune time. Both of these bad boys are classified as Gadget Gangsters, which makes ’em viable for purchase without any additional investigation. Should you choose to, however, we’ll have you know that the Propeller Platform USB is an open-source platform for building your own electronics projects with a new eight-core Parallax Propeller chip; the ProtoPlus model adds video / audio support as well as a “prototyping area.” Tutorials are available in the source links for those inexperienced with Spin, and at just $50 / $15 (respectively), we’d say they’re well worth the purchase if you’re looking to simply get your toes wet. Better known as “become hopelessly addicted to modding” ’round these parts.

Bicyclist Turns his Head Into a Battery Charger

Are you a bicycling enthusiast? Do you own a special pair of specially-designed biking gloves? Do you hold a vehement hatred towards people who drive cars to destinations two blocks away, and also towards pedestrians who dare tread upon your clearly-demarcated bike lane? Do you feel a sense of accomplishment at having biked through a cold winter night even when public transportation could have cut your travel time in half?

If you answered ‘yes’ to any of these questions, then you my friend, are a biker. And we would like to put you and your protective gear to work saving the planet.

One green-minded biker has created a way to convert all that wind passing over his helmet into electricity. This mobile skull-adorned windmills utilize propellers in order to charge embedded batteries (it takes a two-hour ride to fully-charge). The batteries can then be connected to other devices by USB.

However, this isn’t meant to be just another green gadget, but rather [sic]:

We want to use it as a medium to sensibilise the public for environmental topics and to integrate sustainability topics into the lifestye of young people by creating a positive experience.

Squirt water gun robot pesters raccoons, takes orders from Android (video)

It’s not uncommon to see Mr. Android and Sir Arduino team up in the world of homegrown robotics, but Squirt has managed to hop out of the me-too crowd with a downright charming control scheme (and even more charming looks). Put simply, this water gun robot was designed to “water plants and chase away raccoons,” but from a broader perspective, the creator was looking to demonstrate how robotics could be used in small irrigation and well systems. Better still, this is far more than just a robot that’s controlled remotely via smartphone; if you switch it into ‘guard mode,’ it’ll search and destroy — pelting anything “that moves” with a blast of water. And yeah, it can also be controlled via SMS, so even the cats can’t celebrate too quickly once the owner heads out for work. Hit the source link to find out more on how this masterpiece was constructed, or head beyond the break for a quick demo vid.
