Fresh hacks every day
We've all heard the countless arguments about piracy in digital media. However, it appears that 3d printing or other rapid prototyping systems are bringing legal issues to a more physical world. The story goes like this: [Thomas] bought a 3d printer. He's a big fan of warhammer figurines. He spends tons of time creating some custom warhammer figures, and uploads them to thingaverse. Games … [Read more...]
Earlier this month, [Kenneth] picked up an old dot matrix printer at the Silicon Valley Flea Market and subsequently found two cases of tractor feed printer paper. It's a marriage made in heaven for a dot matrix twitter printer. [Kenneth] used a BeagleBone - a tiny single board computer running Linux - to connect to the Internet and fetch any new tweets mentioning KWF every minute or so. The … [Read more...]
If it's true that those with the biggest toys win, a few lucky engineers over at EEW Maschinenbau in Germany just earned a gold medal; they have access to a gigantic CNC machine that is large enough to machine a house. This machine was originally built to manufacture molds for fiberglass wind turbines that are over 50 meters in length. Because building a 50-meter-long CNC machine wasn't … [Read more...]
[Emanuele] is using Google Docs to log his temperature sensor data automatically (translated). We can see a few benefits gained by using this system. One is that you don't have to visit the site of the logging hardware to harvest the data, another is that Google will automatically graph the data for you. Of course this means you need some way to connect your logger to the Internet, but we've seen … [Read more...]
[Dearmash] put together this RGB LED display using triangles for each pixel. It's an interesting deviation from the traditional grid layout. There are two video demos after the break. The first is a plasma-style pattern generated in Processing. The second is a spinning color wheel which would be perfect if synchronized with your Photoshop color spinner. So the physical build is done, and now … [Read more...]
The bicycle tail and head lights that we're accustomed to are small add-on modules. This take on the idea uses strips of LEDs to protect you from behind. They're very bright, matching the pair of LED headlights that are attache to the handlebars. Apparently [A.Davis12] had some LED strips laying around. There's not what we're used to seeing, but they have a similar footprint so you should be … [Read more...]
Some people have a real knack for sourcing parts at the dollar store. [James] is one of those people, having built this Arc Reactor replica using mostly dollar store goods. The light source is an LED disk light that was removed from its enclosure. A sink strainer, the plastic holder from a package of sewing pins, and some wire mesh go together to make the first layer of the bezel. The push-pin … [Read more...]
