Filed under: misc hacks, dailyThis nifty thermostat is actually built from just a few off the shelf components. A Dallas DS1820 1-wire temperature sensor provides and an Olimax ATMega development board. If you're not so handy with the soldering side, you can pull this one off. The device can be programmed by the button cluster and will even output status via the serial port.Read | ... this | Linki... Hackaday.com Tuesday, July 08, 2008 Filed under: news
Do you have a burning desire to fight grizzly bears? If you do, We can't guarantee that the first bear you face will win, but we really can't imagine another outcome unless you use [Troy Hurtubise]'s Mk IV suit, which is currently up for auction. We have discussed the suit before along with several other high-tech power suits, but this is the only one with bear-resistance in mind. The suit features several safety features, including layers of chainmail and titanium.The suit was also featured in the film "Project Grizzly." [Hurtubise] is hoping to sell the suit for $40,000 or more to offset his personal costs, and judging by the current price, he may well make it. [via Engadget]Read |&n... this | Linki...

Hackaday.com Tuesday, July 08, 2008 Nokia Haptikos patent application reveals its technology Filed under: newsWe've been waiting for more information on the Nokia Haptikos, the haptic feedback touchscreen announced last October and largely forgotten until now. We knew that it would be a device that could raise sections of its touchscreen to simulate the feel of buttons or keys, we just weren't sure how Nokia would pull that off. Now we have a better idea, as Nokia's recent patent filing for the Haptikos gives away some juicy details.The secret behind the device's feedback is a "plurality of closely spaced voltage controllable protuberances," or in other words, several small fluid filled compartments just under the screen's surface. Under them are several piezoelectric members that can be controlled independently; when they extend upward, they apply pressure to the fluid compartments, raising the surface of the screen in that area. Nokia has yet to work out all the kinks, but you can see the parts that do work by downloading the Haptikos patent application (PDF file).

While we figure that out, you can do the next best thing: render small planets using Photoshop or GIMP with a few other graphics apps and this guide to making small planets like the one pictured above.The first step is in the photography itself. You'll want an equirectangular panoramic image that includes more natural terrain like grass or dirt than man made terrain like streets or sidewalks, as this is easier to work with. Take approximately six photos from a tripod-mounted camera, turning the camera about 30 degrees after each photo. This should give you a full 360 degree panoramic landscape stitched from the individual photos. Next you'll want to do the actual stitching: this can be done very carefully in Photoshop, but a light imaging app called PTGui makes the job go much more quickly. Resize the image so that Hackaday.com Tuesday, July 08, 2008 Lively, Google's stab at Second Life Filed under: newsGoogle has just released their own avatar based social arena a la Second Life, which is called Lively. It will require a client download and install like the popular MUD, but after that it can be accessed via IE and Firefox. Lively allows user to create their own online spaces that can include natural or human-built settings and customize their avatars (which are relatively cartoonish in comparison to SL avatars). Google's engineering manager for Lively [Niniane Wang] explains that they wanted to create a more socially rich environment than was possible with emotes and other chatroom features. Lively's core functions are not particularly novel, but it does innovate with various web integration features. Videos and images from the internet are viewable from within Lively, and users can embed their own personal Lively areas into their blogs or websites (hello VRML). Lively is not nearly as expansive as Second Life yet, with no form of currency included and only stock ite Hackaday.com Tuesday, July 08, 2008 Major DNS issue causes multivendor patch day Filed under: newsEarlier this year, our friend [Dan Kaminsky] discovered a major DNS issue that could allow hackers to compromise name servers and clients easily. The vulnerability involves cache poisoning, and [Kaminsky] plans to publish the full details of the vulnerability on August 6th. However, he has already begun his work to control it, alerting major authorities early on of the vulnerability. As a result, engineers from many major technology vendors quickly began working on coordinated patches for DNS servers. The patches were all released today; vendors and a CERT advisory urge organizations to apply them today, before the vulnerability becomes common knowledge. More details on the DNS issue can be found in the executive overview (PDF file). [Rich Mogull] interviewed [Dan] for the Network Security Podcast. It doesn't detail the attack but points out that services that use port randomization like OpenDNS are unaffected and that Bind8 is being deprecated.UPDATE: Here's the audio Hackaday.com Tuesday, July 08, 2008 Pedal powered Panzer tank built for crashing parties Filed under: misc hacksA group from Philadelphia PA calling themselves Team pzkpfw decided to recreate a Panzerkampfwagen III, but not entirely according to the original specs. Instead of treads and an engine, they used a system of pedals, gears and chains powered by up to six riders. The team of roughly nine men spent eleven days welding beams and plates, drilling and shaping sprockets, and painting the tank a fearsome pink camouflage. They were planning on crashing the 2nd annual Kensington Kinetic Sculpture Derby with it, which they crashed last year in a pirate ship, but they ended up being too tired from their tooling around to actually do it. There's always next year. Get a look at their promotional video after the break, or if you'll be in the Philly area soon, "visit the tank on Frankford Ave, just north of Norris St in Philadelphia."Read&nb... this | Linki... Hackaday.com Tuesday, July 08, 2008 Aurora open source hardware mixer Filed under: misc hacksWe've seen some fairly impressive mixer projects this year, and the Aurora mixer is no exception. It is a dual channel USB-powered mixer with two linear faders, one crossfader, eight backlit buttons and 24 potentiometers, all built around a PIC 18LF4525 microcontroller. That's all pretty typical for a mixer, but this one is very visually attractive, featuring a clean and stylish form factor and controllable lighting both under the board and in the LEDs backlighting the buttons and knobs.Whether you want to buy one now or build one yourself, the Aurora team has made both possible. You can contact them for pricing if you are ready to buy. If you prefer to build, this is an open source project with full assembly instructions, schematics, drivers, patches and all other source code and information you should need available here. See more photos of the Aurora mixer here, or see it in action after the break. Read |&... this |&nb Hackaday.com Tuesday, July 08, 2008
