[Mazvydas] shares with us, his cheap robot hand. He was inspired by this project, where someone used an Arduino and a glove with some flex sensors to control a pre-made hand. He wanted to go a little more DIY though. He chose a picaxe microcontroller and constructed the hand himself out of twine, some plexi-glass, and some rubber hose. He does ultimately plan on adding glove control as well.
Unfortunately there’s no schematic or source code. Maybe if we ask really nicely he’ll share.
This beautiful music syncronized double helix was made by Syyn labs. Last time we saw them, they had created that amazing rube goldberg style music video for OK Go. This 100 foot long LED DNA strand took over 1000 combined man hours to build. It took 512 LEDs, 32 LED controllers, 4 Arduinos, 4 computers, over a mile of wire and a very dedicated team, which included [Eliot Phillips]. It takes input from beatmatching/VU software as well as a 32 button console or an iPad. You can catch a video of it in action after the break, and they plan on releasing a timelapse of the build in the near future.
Here’s a build log for a nice beach winch for your next trip out to go beachwinching. Beachwinching is when you use a fast winch on shore to pull you in, allowing you to wakeboard, wakeskate, or water skii without the need of waves or a boat or jet ski to pull you along. While there’s nothing amazingly groundbreaking here, we do love a nicely documented build log. We think a remote way to initialize the pull would be nice too.

[littlebird] posted a tutorial on making electronic dice. He’s using an ATmega328 for the numbers work, and a mercury switch to activate it all. A nice blue enclosure to match the blue LEDs he’s using for the number display wraps it up nicely. Of course, someone had to mention that this was an amazing amount of over kill and it could just be done with a 555 timer like they used to do “back in the day”. [littlebird] responded with another tutorial to prove that he hadn’t forgotten how to work with the basics. He goes on to point out, now that we see both in action, that he can expand his microcontroller based one quickly with a few lines of code, where every new feature added to the 555 timer version would require additional components.
You can catch videos of both after the break.
[Jason Scott], data historian extraordinaire gave this fantastic speech at Defcon 18 about the history of inter-pirate piracy. At an hour long, it is an enthralling journey through computer history, especially pertaining to piracy. Take a seat, no matter how much you know about security and piracy, you are likely to learn a few things. We find the lesser discussed issues like pirates stealing other pirates work interesting, as well as the part where pirates have to crack really boring software to have a release when there’s nothing better out there. Also worth noting, according to [Jason], the demoscene evolved from the little opening sequences from cracks. There are just too many interesting aspects to note here, even some porn related stories during the BBS days.
This is a great lesson from someone who is both knowledgeable and entertaining. [Jason] teaches this stuff without ever sounding stuffy, boring, or overly technical. Catch the video after the break.

[Greasetattoo] shares the process of building his wooden quadcopter body that won 2nd place in the Minnesota state fair. His plans were purchased as a kit back in 1999, but he never got around to actually building them. The original plans called for a foam board body, but he felt that a wooden piece of art would be much nicer. This build isn’t focusing on the electronics, they’re just a kit from Mikrokopter. Instead, it is a log of the entire process of making the beautiful wooden body. He really put some nice detail in there from the layered and nicely finished dome to the little oak sleeves for his motors. Great job [Greasetattoo].
We love games here but we don’t often get a reason to write about them. This, however, is worth mentioning. The indie hit Minecraft is eating the entire internet right now. The game itself is hit and miss amongst our staff, but this project is unanimously accepted as awesome. [Theinternetftw} has created a simulation of the ALU section of a 16bit processor. He can set it in motion and run around watching as the states change. This is part of an even bigger project to create the entire processor as shown in the book “The Elements of Computer Systems“.
For those that are wondering how long it took him to place all of those pieces, he actually imported most of it from another program. You can get more details on how they pulled this off in this forum thread. Be sure to catch the video after the break.
