I recently had the chance to visit Belgrade and take part in the Hackaday | Belgrade conference. Whenever I travel, I like to make some extra field trips to explore the area. This Serbian trip included a tour of electronics manufacturing, some excellent museums, and a startup that is weaving FPGAs into servers and PCIe cards.
There’s some debate on which program gets the infamous title of “First Computer Virus”. There were a few for MS-DOS machines in the 80s and even one that spread through ARPANET in the 70s. Even John von Neumann theorized that programs might one day self-replicate. To compile all of these early examples of malware, and possibly settle this question once and for all, [Mikko Hypponen] has started collecting many of the early malware programs into a Museum of Malware.
While unlucky (or careless) users today are confronted with entire hard drive encryption viruses (or worse), a lot of the early viruses were relatively harmless. Examples include Brain which spread via floppy disk, the experimental ARPANET virus, or Elk Cloner which, despite many geniuses falsely claiming that Apples are immune to viruses, infected Mac computers of the 80s. [Mikko] has collected many more from this era that can be downloaded or demonstrated in a browser.
Retrocomputing is an active community, with users keeping gear of this era up and running despite it being 30+ years old. This software, while malicious at the time, is a great look into what the personal computing world was like in its infancy. And don’t forget, if you have a beige computer from a bygone era, you can always load up our Retro Page.
Thanks to [chad] for the tip!
Here’s a tale that warms our hearts. [Gord] is helping out the local living-history museum by rehabbing a historic woodworking tool that they want to add to their live demo woodshop. It’s a hundred-year-old manual drill press that has seen a ton of use.
There are three things that [Gord] has going for him. First off, the Champion Blower and Forge Co. built them to last. Second, he’s not really working on a deadline; the museum doesn’t need it back until May. And third, [Gord] has the tools he needs to do this right.
After cleaning and blasting [Gord] gets down to the really interesting repairs. First off, it wouldn’t be a drill press if someone hadn’t tried to drill through the table at some point. TIG welding filled it up and some milling brought it back. This same method was used again to make a beautiful custom replacement ACME rod. Throwing in a custom bushing replacement, turned wooden handle, and a several other fabricated parts, and [Gord] had the press working again. Check out the mechanism in the video below that shows the crank action turns the bit and a cam advances it through the work piece.
Here’s another example of how today’s rapid-prototyping technologies are allowing Artists and Craftsmen to create interactive works of art rapidly and easily. [Kati Hyypa] and [Niklas Roy] teamed up to transform a classic painting in to an interactive exhibit. It’s a painting of Adam, Eve and the apple with a joystick attached. Spectators can control the destiny of the apple with the joystick and thus explore the painting.
The “Forbidden Fruit Machine” is based on a painting called “The Fall of Man” created by [Cornelis Cornelisz van Haarlem] in 1592. The painting depicts Eve and Adam in the Garden of Eden, being tempted by the serpent to eat the forbidden fruit. A public domain, high-resolution scan of the painting is available for download from the Rijksmuseum Amsterdam. Starting with that, the arms were edited out, and replaced with articulated versions (mounted on acrylic) driven by servos. The apple was mounted on a X-Y gantry driven by two stepper motors. These are driven by a motor shield, which is controlled by an Arduino Uno. The Uno also controls a Music Maker shield to play the various audio tracks and sound effects. Finally, an additional Arduino Pro-Mini is used to control the LED lighting effects via a Darlington driver and also connect to the end stops for the X-Y gantry. The joystick is connected to the analog ports of the Uno.
The LED’s give clues on where to move the apple using the joystick, and pressing the red button plays an appropriate audio or sound effect. For example, pressing the button over the cat at Eve and Adam’s feet elicits a heart-breaking meow, while letting Eve eat the apple results in an even more dramatic effect including a thunder storm.
The machine is open source with code posted on Github and 3d files on Youmagine. Watch a video after the break. The artist’s names may be familiar to some some readers – that’s because both have had their earlier work featured on our blog, for example this awesome ball sucking machine and another one too.
Somehow, and don’t ask us how, the venue we chose for the Hackaday Prize party was perfect for Hackaday-related shenanigans. There was a Hackerspace right around the corner, a computer history museum in a warehouse nearby, and an amazing video game archive barely 100 meters away from our venue.
The VideoGamingArchive is an amazing collection of video games from the era where video games came in boxes with real manuals, and you needed to be sure you bought the game compatible with your system. Inside, one wall is dedicated to the old cardboard computer boxes, indexed partly by system and partly by how cool they look, while the other wall was dedicated to games from the previous five generations of consoles.
[Nils] was kind enough to give me a tour. You can check that video out below, with some more pics below that. If you’re wondering, yes, that is a sealed copy of Chrono Trigger, and no, I have no idea what it’s worth.
Wander through a well-funded museum these days and you’re likely to find interactive exhibits scattered around, such as this sleek 50″ projection-based multitouch table. The company responsible for this beauty, Ideum, has discontinued the MT-50 model in favor of an LCD version, and has released the plans for the old model as part of the Open Exhibits initiative. This is a good thing for… well, everyone!
The frame consists of aluminum struts that crisscross through an all-steel body, which sits on casters for mobility. The computer specs seem comparable to a modern gaming rig, and rely on IEEE1394 inputs for the cameras. The costs start to pile up with the multiple row of high-intensity infrared LED strips, which can run $200 per roll. The glass is a custom made, 10mm thick sheet with projection film on one side and is micro-etched to reduce reflections and increase the viewing angle to nearly 180 degrees. The projector is an InFocus IN-1503, which has an impressively short projection throw ratio, and a final resolution of 1280×720.
The estimated price tag mentioned in the comments is pretty steep: $12k-16k. Let us know with your own comment what alternative parts might cut the cost, and watch the video overview of the table below, plus a video demonstration of its durability. For another DIY museum build, check out Bill Porter’s “Reaction Time Challenge.”
We’re not sure where [Bill Porter] finds all of his free time, but we’re glad he’s put it to such good use by building an exhibit piece for the local science museum: Reaction Time Challenge. It’s likely that we were all inspired to love science as kids in a museum like this, and [Bill’s] contribution is already fascinating its young audience. The challenge lets two participants test how fast they can smack a big red button after a randomly-generated countdown. The time taken for the players to react is translated into the RGB LED strips, measuring how fast they managed to hit the button.
Builds like this one need to clearly communicate how they should be used; you don’t want confused children bamming around on your cabinet. First, [Bill] guts the dim LEDs inside the big plastic buttons and replaces them with some brighter ones. To keep the connections clean, he takes the cannibalized ends of an Ethernet cable and hooks the speaker and buttons to an Ethernet jack. The jack sits snugly in a project box where it connects to an Arduino. Two RGB LED strips run from the opposite end of the box, daisy-chaining from the bottom of the cabinet to the top, then back down again. See it all come together in the video after the break.
[Bill’s] museum must be pretty lucky; he resurrected the “Freeze Frame” exhibit for them just over a year ago and has done a bunch of other projects for them over the years.
