Hack a Day
Here’s another hack that we would definitely discourage you from trying at home, 244 9 volt batteries wired in series. There’s really not much more to it than that, but [jersagfast] takes this setup through its paces arcing through air first, a LED light second, and then a CD. The air arc is probably the [...]

We think you’ll turn a few heads in Central Park if you’re driving a water melon around when everyone else is piloting sailboats. This watermelon is both sea worthy and radio controlled thanks to the work which [Starting Electronics] put into it. We used this image because it shows you what’s inside of the hull, [...]

You can have a lot of fun tinkering with the Raspberry Pi. But in addition to the low-cost hobby potential it is actually a great choice for serious data harvesting. This air quality monitor is a great example of that. The standalone package can be taped, screwed, bolted, or bungeed at the target location with [...]

He’s just pointing in this image, but this Air Harp can be played using many fingers as once. It’s a demonstration which [Adam Somers] threw together in one weekend when working with the Leap Motion developer board. We first heard about this slick piece of hardware back in May and from the looks of it this [...]

This quick and easy evaporative cooler might be just the thing the next time the air conditioning goes on the fritz. [Stephen] saw an eBay listing for a personal air conditioner that used a moist sponge and fan to send some cool relief your way. But he wanted to run his own test to see [...]

If you’re flying through the air in a non-powered vehicle your rate of descent is something that you want to keep any eye one. With that in mind, [Adrian] decided to design his own Variometer (translated) what will have a place in the cockpit next to the other instrumentation. It emits a pitch whose frequency is dictated [...]

In an effort to ease the process of soldering Ball Grid Array (BGA) chips at home [Roger] rigged up a hands-free solution for his hot air equipment. The main component in the build is an Aoyue hot air rework station that he already had in his workshop. He wanted an adjustable mount that would hold [...]

We’ve seen air fresheners used for many hacks here at hackaday. This one is a bit different as it uses the PIR sensor assembly to turn on LEDs in sequence, rather than reversing a motor. Generally, the motor would be reversed by the fact that this assembly is reversing the voltage on a motor (see [...]

[Kevin] wanted to check out the air patterns present when his 3D printer is in action. This is useful research; slight differences in temperature can affect the quality of his prints. Instead of something like a thermometer, [Kevin] decided to use Schlieren photography to visualize the air around his 3D printer. If you’ve ever seen very [...]

[Matt] emailed in to show us how he has improved his bubble display since the last time we saw it. If you recall from last time, he was having issues with the air pressure dropping when multiple bubbles were released, resulting in smaller bubbles. This time around, he has added an aesthetically pleasing air reservoir [...]

Being an air traffic controller is a very cool career path – you get to see planes flying around on computer screens and orchestrate their flight paths like a modern-day magician. [Balint] sent in a DIY aviation mapper so anyone can see the flight paths of all the planes in the air, with the added bonus [...]

The pressurized air from a standard air compressor is fine for most uses. But some applications like plasma cutting call for low-humidity air and the hardware available to facilitate this can cost a bundle. [Roland] and his cohorts at TX/RX Labs (a Houston, Texas Hackerspace) just built this air drying system. It works using a desiccant; [...]

Flashing LEDs for a persistence of vision display are on bicycle wheels, alarm clocks, and even light painting sticks to draw images in the air. What if you wanted to plot an image in the air (translation) with a single LED? That’s what [acorv] did after taking a cue from a polar plotter. Like the polar plotter and [...]

It’s really amazing what you can find at military surplus shops. [David] just built a radiation detector out of a DT-590A scintillation probe originally made to test if Air Force bases were contaminated with Plutonium. Who says nothing good came out of massive nuclear arsenals? DT-590A / PDR-56 Gamma ray probes were made obsolete by the US Air [...]

[Allan] needed a small vacuum chamber to get all the air out of clear casting resin. Degassing is a simple step in casting that improves the finished product immensely. The problem, though, is building a vacuum chamber. [Allan]‘s chamber seems easy enough to build, and pulls enough air out to get to 0.1 atmospheres. After [...]

You may have seen an air powered engine at some point, but most are made out of some sort of metal. This engine, however, is made entirely out of wood (and fasteners). One might wonder how a design like this was conceived, but this may be explained by [Woodgears.ca's] tagline: “An engineer’s approach to woodworking.” [...]

Who needs a tactile interface when you can wave your hands in the air to make music? Air String makes that possible and surprisingly it does so without the use of a Kinect sensor. In the image above, you can see that two green marker caps are used as plectra to draw music out of [...]

Check out this setup that [Ruenahcmohr] is using in his air muscle experiments. The orange mesh contains an air bladder that is connected to a hose on the right side. The bladder can be filled, or emptied with two solenoid valves not seen here (but you can get a good look in the video after [...]

A year ago [Lochie] bought an Airwick automatic air freshener, and while he thought it was a cool gadget, the freshening spray and the novelty ran out in short order.

For anyone that works in a large office building, odds are you know the pains of dealing with a poorly regulated HVAC system.

The Air Kraken is a bicycle for demon spawn. Well, that’s what it reminds us of anyway.

The over-grown tricycle built for two is more than [...]

Although this isn’t the first pneumatic air cannon to be featured on HAD, this “paintball shotgun” is certainly one of the coolest. While most air cannons have little practical use besides looking awesome and being cool to play with, this cannon, according to it’s maker, has actually been used successfully in actual paintball competition. The [...]

[Jeremy] wrote in to show off his latest creation. he has built a two barrel pneumatic air cannon.

[Ben Krasnow] is working on a force-feedback joystick. It centers around the concept of an air muscle which transfers pressure into linear motion.

Keeping live plants in an aquarium happy can be quite a chore. One of the frequent rituals is adding fertilizer, which is called dosing.

Did you know that a standard camera flash is much too slow to capture high quality images of bullets? A relatively long flash duration results in blurred images of the bullet.

Wirevolution
Well, the Apple iPad is out. Time will tell whether its success will equal that of the iPhone, the Apple TV or the MacBook Air. I’m confident it will do better than the Newton. The announcement contained a few interesting points, the most significant of which is that it uses a new Apple proprietary processor, the A4. Some reviewers have described the iPad as very fast, and with good battery life; these are indications that the processor is power efficient. Because of its software similarities to the iPhone, the architecture is probably ARM-based, with special P.A. Semi sauce for power and speed. On the other hand, it could be a spin of the PWRficient CPU, which is PowerPC based. In that light, it is interesting to review Apple’s reasons for abandoning the Power PC in 2005. Maybe Apple’s massive increase in sales volume since then has made Intel’s economies of scale less overwhelming?
The price is right, as is an option to go without a 3G radio. The weight is double that of a Kindle, and half that of a MacBook Air.
I am disappointed that there is no user-pointing camera, because as I mentioned earlier, I think that videophone will be a major use for this class of device.
Update 3 February 2010: Linley Gwenapp wrote up some speculations in his newsletter.

remote-exploit & backtrack
J ai fouillé un peu partout pour un bon tuto sur kismet mais ceux que je trouve on l'air de dater un peu
j' ai essayé de les appliquer( à defaut de les comprendre) mais le resultat que j' affiche est totalement différent de ce qu'on trouve dans les Thread , du fait je plane un peu et je n' en tire rien de concluant.
est ce que la version de kismet inclue dans BT4 est si differente de celles qui sont expliquées sur ce forum ?
