The quick and simple portal gun hack was published a little ver a week ago and has cleared almost 1.5 million views. This is just a taste of things to come as we plunge into creating more fun original content for hackaday. If you haven’t yet, you should go subscribe to our youtube channel.
We have many more exciting projects planned for the near future. Projects involving high voltage, lasers, and thermite! We could always use more ideas though. What projects would you like to see done? Think big, we want to remind people just how awesome hacking can be!
We now have access to some high speed cameras, a wonderful and professional gentleman named [Jay] who is an astounding video editor, and quite possibly the brightest readership in the universe. Let us know your ideas for awesome projects!
Whether you’re used to dropped wifi connections, or your housemates are using up all the bandwidth for streaming, we’ve all see the spinning octet of disks that is the YouTube loading animation. [technocrat] thought it would be a great idea to actually become YouTube and set out on designing a physical manifestation of the loading animation.
[technocrat] used eight ping-pong balls as the main structure of the build. After drilling each ping-pong ball and gluing white LEDs in, the only thing left was to connect everything up to an Arduino. The code loops through each LED and provides the ‘light trail’ animation YouTube has burned into our memory.
To complete the build, [technocrat] attached his physical loading animation to a black t-shirt emblazoned with the YouTube logo to make everything more understandable. While it may not be as colorful as the beachball of death or as conceptual as the Windows ‘spinning hourglass’, we’re really liking this build. Check out the video after the break.

The Earth orbits the Sun every 365.256 days. Because this number isn’t a whole number, an extra day is tacked onto February every four years, unless the year is evenly divisible by 100, except in cases where the year is divisible by 400, or something like that. To commemorate this calendar hack, here’s some stuff that has rolled in over the last week or so.
[Brian] sent in this marble-based sequencer that sounds like someone is running MIDI into an Atari 2600. There are photoresistors in there somewhere, and it really reminds us of those thingamagoop robots.
[Mike] uses YouTube as his music library. While this is a perfectly acceptable way to listen to music, the user interface is terrible. To solve this problem, [Mike] is downloading videos from the command line, automagically converting them to MP3, and playing them over speakers. It works well with SSH, so we’ll call this a win.
Key card lock
[valenitn] just joined the MIT Media Lab, but something was terribly wrong with his keys – an ID card was required to get into the building, but a key was necessary to get into his office. He doesn’t need the key anymore, at least since he modded his office door. Check out the video.
Pop Tart Cat is everywhere
[skywodd] saw our writeup on the Maximite Basic computer and figured he could send in a project he’s been working on. He programmed his Maximite to sing the nyan cat song and then created a BASIC music player. Nice job, [skywodd].
Not sure if brilliant or insane
[Vikash] ran across a forum post where a user named [I Shooter] describes his setup to dual-boot Windows and Linux: [I Shooter] connected data cables to a pair of SATA hard drives, one loaded up with Windows, the other with Linux. The power cables are switched using relays so only one drive is powered at a time. [I Shooter] gets a ton of points for creativity, but there’s a reason this brute force hardware dual-boot setup isn’t more common. We wish there were pictures of this one.
Behold the uWave, a microwave oven that plays YouTube videos while it cooks. [Kevin] and three classmates at the University of Pennsylvania developed the project for the 2011 PennApps hackathon. It uses a tablet computer to replace the boring old spinning food display microwaves are known for. Now, an Arduino reads the cook time and sends that information to a server via its Ethernet shield. The server then searches YouTube for a video that approximately matches the cooking time, then pushed that video to the tablet to start playing. The video demonstration embedded after the break shows this, as well as the tweet that the machine sends at the beginning of the process.
It’s an interesting concept, and we think the code used to push a video to the tablet has a lot of other applications (we’re keeping this one bookmarked). On the other hand, we wonder how long it will take for public microwaves to become ad-supported? We’re thinking it’s hard for companies selling antacids, acid reflux medicine, Cup ‘o Soup, and Hot Pockets to resist this opportunity.

It seems like every hackerspace has their own means of communicating status messages to their members. The hackers at [MetaLab] in Vienna have put together a rather novel way (Google translation) of letting the world know they have completed a project. While some hackerspaces simply notify their members that they are open for business, this hack takes things a step further.
When a project is deemed complete, the camera is removed from the dock, and any number of videos can be recorded. When the camera is returned to the dock, a canned introduction video is added to the recordings, then everything is automatically uploaded to YouTube. No extra time is required, no video editing needs to be done – their work hits the Internet immediately once they have finished filming it.
It’s a great idea, and something that every hackerspace should have. It would be even better to see these things installed in public areas to allow for immediate reporting of events as they occur.
If you are so inclined, be sure to check out [MetaLab’s] YouTube channel.
[Charlie X-Ray] is having some modern fun with the phone system by pulling dialed numbers from the audio track of YouTube videos (translated). The first step was to find a video where a telephone is being dialed and the sounds of the keypresses are audible. You can’t tell those tones apart, but a computer can. That’s because each number pressed generates a combination of two out of seven closely related frequencies. [Charlie] isolated the audio using Audacity, then wrote a python script to generate a spectrogram like the one above. By matching up the two dark nodes you can establish which two frequencies were played and decode the phone number being dialed. So how does this work again… find audio of a phone being dialed, decode the number.. profit?
SecurityTube is a site which has recently caught our attention. The site has quite a variety of videos from various sources related to security and hacking. Videos range from DEFCON talks, to documentaries, step by step how tos, and even proof of concept vulnerability videos. It’s certainly a great resource for anyone looking for something a bit more involved then a plain text writeup, and offers a way for you to catch those hacker conference talks you missed. Many of the videos come with a bit of a background information as well, so it’s far more informative then your regular YouTube videos. This site is certainly going to become a very valuable resource for many people, and is certainly a great way to kill an afternoon while still learning something.
