Found: Artifacts From The Future

July 29, 2008 by 11 Comments


MetaFilter is reporting that Wired magazine (available on paper) has killed one of our favorite features. Found: Artifacts From the Future was a back page that asked artists and designers to create possible future products. While the magazine generally had a positive view, even in its sloppy use of infoporn, Found always seemed to have a comforting cynicism. Products appeared helpful on the surface, but still exhibited modern pitfalls: Even if you took the big leap to get a Bluetooth implant, it still required a two year contract. The Responsibeer could tell exactly how drunk you were, but did nothing to prevent localized debauchery. A Smart Windshield provided info on unsafe drivers… while obscuring your view.

The short of it is: Found was our kind of futurism. It was excited about new technology while emphasizing all the frustrations we currently have trying to get consumer products to do what we want. It’s sad to see something that got people thinking beyond the now go away. MeFi has conveniently assembled links to all the online Found features.

Solder Paste Fridge

July 28, 2008 by 4 Comments


MightyOhm’s laboratories have recently decided to start tackling more surface mount work. As part of this upgrade to SMD hot air reflow stations, they’re handling a lot of solder paste. Solder paste is happy at less than 50degF and above freezing, and [Jeff] didn’t want to chance that lead infiltrating his Manwich, so he built this solder paste fridge. The main unit is a standard 12V peltier based travel cooler. He attached a surplus PID controller with a K-type thermocouple to maintain the temperature while preventing the cooler from being always on. The only adjustment he really had to make was adding a bleed resistor to force the MOSFET to turn off. You can find more pictures of his project on Flickr.

RC Duck Decoys

July 28, 2008 by 6 Comments

Here’s something for those of you who always wanted your projects to attract more shotgun blasts. [courtney] built two RC duck decoys. The decoys were only $10 to begin with and the RC submarines were an additional $20 at RadioShack. The construction is fairly clever, using a heat gun to conform the duck body to the submarine. We think the most surprising bit is that this has been done many times over: RC duck with rocket launcher, RC duck cam, and someone is producing commercial ones. Whatever you end up putting in your remotely operated duck, we’ll be sure to include it in our next movie plot threat entry.

Synchronizing Fireflies NG

July 28, 2008 by 9 Comments


[Alex] from Tinkerlog has revisited an old project with Synchronizing Fireflies NG. Fascinated by how fireflies blink at same rate and synchronize with each other, he built a digital version. Each board has an RGB LED and a phototransistor or photoresistor. A ping-pong ball is used as a diffuser. The blink rate is controlled by an ATtiny13v. The board power can be daisy chained, but each firefly mote operates independently of the others. The microcontroller has a fixed flash rate and monitors for other flashes. It attempts to sync by flashing earlier. The color of the LED expresses how satisfied the firefly is with its current sync. You can see a video of eight fireflies attempting to self organize embedded below.

HOPE 2008: YouTomb, A Free Culture Hack

July 25, 2008 by 9 Comments


YouTomb is a research project designed by the MIT Free Culture group to track video take downs on YouTube. To succeed, the team needed to track every single video on YouTube… which is close to impossible. Instead, they built several “explorer” scripts to track what videos were interesting. One explorer tracks all of YouTube’s lists: recommended, featured, most active, and more. Another explorer picks up every video submitted to YouTube, and a third crawls Technorati.

The explorers just find the videos; a separate group of scanner scripts checks the current status of videos. It checks both the new videos and ones that have been killed to see if they return. YouTomb archives every video it finds. They display the thumbnail of the video under fair use, but they’re still determining whether they can display each video in full.

Drill Powered Mini Bike

July 24, 2008 by 25 Comments


DPX Systems seems to deal exclusively in devices powered by handheld drills. In addition to the mini bike in the video above, they’ve made systems for wheelchairs, toolboxes, and hoists. The device costs $630, but we know most of you just need prompting that something is possible to be well on your way to building your own version. We’re still more fond of weed whacker machines.

DNS Cache Poisoning Webcast

July 24, 2008 by 4 Comments


UPDATE: Full audio of the webcast is now available

Today Black Hat held a preview webcast with [Dan Kaminsky] about the massive DNS bug he discovered. On July 8th, multiple vendors announced a patch for an undisclosed DNS vulnerability. [Dan Kaminisky] did not release the details of the vulnerability at that time, but encouraged security researchers to not release their work, if they did happen to discover the bug. On the 21st, the full description of the vulnerability was leaked.

In today’s webcast, [Dan] covered how he felt about the handling of the vulnerability and answered a few questions about it. He started out by talking about how he stumbled across the bug; he was working on how to make content distribution faster by using DNS to find the server closest to the client. The new attack works because DNS servers not using port randomization make it easy for the attacker to forge a response. You can read the specifics of the attack here.
