    hackaday.com 01 Mar '13, 9pm

    For as much as we enjoy rockets, explosives, and other dangerous things, we haven’t said a word about the works of [Richard Nakka] . He’s the original hacker rocketeer with thousands of words dedicated to the craft of making things move straight up really fast. One of his more interes...

    Take a look at the image above to see his alterations to the mainboard. The jumpers soldered to the two chips at the top are by far the trickiest part of the project. Each of the pins he soldered to needed to first be lifted from the PCB pad so that they no longer make contact with th...

    Oreo-creme hater builds Rube Goldberg CNC router to remove the Stuf

    hackaday.com 01 Mar '13, 5pm

    Look, we understand the need to find a project to occupy your time and interest. So we’re not going to ask the wrong question (why?) for this one. This guy hates the creme that connects the chocolate cookies to make an Oreo. So he built a complicated system to separate the cookies and...

    Soluble support structure can be used with any extruder-based 3D printer

    hackaday.com 01 Mar '13, 3pm

    One of the issues with extruder-based 3D printing is that it can be very difficult to print objects that have voids in them. You simply must have something to deposit the soft material on until it has a chance to harden. [Matt] found a solution which should work for any extruder-based...

    Here’s an interesting hack. It’s a small pick-up truck with a Dope Cannon attached to it . Sure, it looks more like something you’d see in Syria , but this item was actually seized in Mexico where it was being used to fire 30 pound slugs of Marijuana over the border fence with the US....

    hackaday.com 28 Feb '13, 9pm

    The business end of the bending tool is the red-hot Nichrome wire running through the aluminum channel. That channel is used to protect the MDF and act as a spacer so that the wire doesn’t touch the acrylic. On the near side the wire is anchored with a screw, but on the far end it is ...

  • Hacking a Ham Radio

    hackaday.com 28 Feb '13, 7pm

    Perhaps type acceptance would be an issue. As hams the FCC does allow us to build or modify our own devices but we aren’t allowed to market them without type acceptance. I’m thinking you would have to take a two-micro approach. One controls the transmit vfo/power while the other is th...

    Here’s a design that lets you make acrylic enclosures without using fasteners . The red outline in the diagram above is a bit hard to make out. But look closely and you’ll realize that there is very little material which has been removed to form the clip. This uses the rigidity/flexib...

  • Interpreting Brainf*#k on an AVR

    hackaday.com 27 Feb '13, 9pm

    As for why [Dan] would want an AVR to build an interpreter for a language that is nearly unreadable by humans, we honestly have no idea other than the common, ‘because it’s there’ sentiment. There are some pretty cool projects out there that use brainfuck, including this genetic algor...

    Hacking a radio controlled spy device for overly attached girlfriend.

    hackaday.com 27 Feb '13, 5pm

    I ultimately decided I would get a very fast and small radio controlled car to use as a platform, and I would use the guts of the Intruder as the spy portion. This worked very well. Then, I took a trip to one of the nicer hobby stores in town, Hobby Town . I explained my project and t...

    hackaday.com 27 Feb '13, 3pm

    Some people see 3D printers as expensive and slow devices for replicating bracelets, whistles, and Yoda heads. Until the world transitions to a plastic octopus-based economy, those of us with 3D printers will have to find something useful for these tools. Bayesian Empiritheurgy out of...

    hackaday.com 27 Feb '13, 11am

    Actually the prop arc is kind of small, so sticking random body parts in it is not what most worries me. What most worries me is that it’s a wooden propeller, which have been known to splinter, and fracture and throw a sharp stake out at high velocity. In it’s intended use on a model ...

    Taking the pain out of making custom Eagle parts

    hackaday.com 26 Feb '13, 3pm

    One thing that’s really convenient for custom Eagle parts is that most components are DIPs or some sort of leaded SMD component. [Dave]‘s script takes the dimensional data from any chip’s datasheet and creates a custom outline for each part. The inputs and outputs can also be ripped d...
