What Kind Of LED Matrix Does Your Vodka Come With?

April 14, 2010 by Mike Szczys 40 Comments

Medea Vodka comes with a bottle that includes a blue scrolling LED Marquee. OK, great? It’s an interesting marketing ploy but kind of a waste don’t you think? Friends, it’s up to us to repurpose this hardware. It can’t be that difficult to hack into the programmable display and make it do your bidding. Our friend Google tells us that you can get your hands on this 750 milliliter bottle for about $40. That’s around $25 more than a passable grade of Vodka sells for, a mere pittance for the challenge of cracking open the hardware for fun and profit. Don’t forget to document your work and tip us off once you’ve accomplished something. See Medea’s programming instructional video after the break. Oh yeah, remember to hack first and drink later… cheap soldering irons get hot!

By Popular Demand: The OK Go Rube Goldberg Machine

March 20, 2010 by Mike Szczys 16 Comments

We’ve received many tips regarding the OK Go video that features a Rube Goldberg machine. If you haven’t seen it yet, check out their video after the break. This is the rare instance when a YouTube video features an audio track with the full endorsement of the artists that recorded it.

Our first thought when watching this? Who are the lucky dogs who got paid to design and build that contraption? You don’t have to scratch your head over that one, the Band has posted a four-part video series talking about the machine and documenting the design meetings and build process (those videos also after the break). The engineer artists at Syyn Labs were tapped to pull off the meticulous mayhem and we think they did a stellar job. There’s been a lot of press about the work, but our favorite was over at Wired because it details the process, not the end product.

The best part about Rube Goldberg Machines is that asking “why?” is the wrong questions. The sheer joy of the build makes taking over a house or over-complicating the fulfillment of hunger worth it.

Tax-exempt Geek Group Hit With Huge Tax Bill

March 16, 2010 by Mike Szczys 75 Comments

Non-profit hackerspace The Geek Group has been hit with a hefty tax bill despite their tax-exempt status. We featured a boom camera built by the organization back in November. It is the goal of The Geek Group to fulfill the thirst to explore and create by providing facilities, peer group, and camaraderie that make knowledge and learning not only acceptable, but desirable. In the video after the break you can hear a bit about the organization’s role in servicing donated computers and putting them out into the community, as well as its role in education through groups like the Boy Scouts of America.

This is all done without the goal for profit and accordingly they have attained 501(c)(3) status with the federal government (we’ve seen their 990 forms stating this). To the best of our knowledge this doesn’t mean that they don’t need to pay property taxes, but it does make property taxes ridiculously low (we’ve heard of one cent per acre for non-profit land holdings before). That’s why it comes as quite a surprise when the township slaps a sticker on the doors giving notice of seizure and demanding payment for $47,652.78 in back taxes or the assets will be auctioned off. The entire story, from The Geek Group’s point of view, unfolds in a video of the quarterly Board of Directors meeting from last Saturday.

We’re hoping this is just a mistake and can be remedied. That being said, it’s not easy to run this type of operation. It’s unfortunate that the Board of Directors needs to deal with a tax battle in addition to fulfilling the mission of the organization. Good luck to them in navigating the road ahead.

3D Printing On A Much Larger Scale

March 15, 2010 by Mike Szczys 44 Comments

The end goal of this giant rapid prototyping machine is to print buildings. We’re not holding our breath for a brand new Flintstones-esque abode, but their whimsical suggesting of printed buildings on the moon seems like science fiction with potential. The machine operates similar to a RepRap but instead of plastic parts, it prints stone by binding sand with epoxy. This method is not revolutionary, but hasn’t really been seen in applications larger than a square meter or so. It’s fun to see the things we dabble in heading for industrial production applications.

Google Unveils API To PowerMeter

March 4, 2010 by Mike Szczys 32 Comments

Google’s tentacles continue to wrap around every portion of our lives with the addition of an API for their PowerMeter software. The PowerMeter tool works with smart electricity meters to monitor and display power usage in the home. This will allow manufacturers (and hackers alike) to design new devices with the Google interface in mind.

We’ve got an old-fashioned power meter with a spinning dial and no blinking LED. This means we can’t monitor that blink to add our own PowerMeter interface. But if you do have an easy way to grab data from your meter you can design a home system that takes full advantage of Google’s tools.

Ok, who’s going to be the first to have their Google PowerMeter-compatible hack featured on Hackaday?

Chip And Pin Broken And Other Security Threats

February 12, 2010 by Mike Szczys 22 Comments

Another exploit has been found in the Chip and PIN system. The exploit is a man-in-the middle attack that wouldn’t take too much know-how to pull off. You can watch the BBC report on the issue or check out the paper (PDF) published by the team that found the vulnerability. A stolen card resides in a reader that connects to a dummy card via a small cable. When the dummy card is inserted into a card reader, any PIN can be used to complete the transaction. The chip on the original card gets confirmation that the sale was completed via signature and the vendor’s card reader gets confirmation that the pin was correct. The UK based Chip and PIN system seems like a great idea, but it has had its share of security loopholes. This makes us wonder how hard it is to roll out security patches to the hardware readers in the system. Obviously this needs to be patch but does it take a technician visiting each terminal to flash an upgrade?

Switching to the topic of wide-scale attacks, we caught the NPR interview with [James Lewis] on Wednesday when they discussed the growing threat of Cyberterroism. He feels an attack on the US electrical grid is currently the biggest threat and will happen in the next ten years. Obviously taking the grid down would endanger lives and bring things to a standstill; traffic lights, refrigeration, heat, etc. We’re just glad that when asked if he thinks there is already malicious code residing in the control system, he doesn’t think that’s the case.

Performance Oddities

February 7, 2010 by Mike Szczys 20 Comments

[Mario the Magician] wrote in to let us know that he makes Hackaday a priority every morning with his coffee. Well, so do we. He also included a link to his homepage when submitting this revelation. The juicy details that are as much of a fix as the caffeine in the coffee are missing from his posts. But the hacks are solid.

Magicians are hackers. If you could go out and buy the props, the concept are unlikely to impress anyone. [Mario] demonstrates his Nickel Box and a Jedi Mind Trick he built. The Nickel Box is a mechanical contraption that somehow transports a coin from one part of a cigar box to a tiny little enclosure on top of it. The Jedi Mind Trick uses a microcontroller and an old Star Wars soundtrack cassette tape box to put on a light and sound show while it recovers your chosen card from a shuffled deck. Great demonstrations, but no word on what’s going on inside.

[Mario’s] also has a collection of… performance oddities. His talking television takes an audio input and displays a 1950’s-esque oscilloscope effect on an old TV. He’s attempting to stop his heart, or burn the house down, or both with a flyback transformer lightning box. And his drawing automaton, well, you’ll just have to see it.

We believe in electrons, not magic (even though some say there are no electrons). So we want to know how those magic props are built. Like any good magician, [Mario] probably won’t reveal his secrets. If you’ve got the goods this your chance. Write a post detailing your magical prop builds and send them our way. If it’s well done we’ll feature it here on Hackaday.
