Welcome Back, HackaDay Links

While browsing the web for new and interesting hacks to show you guys, we run across all kinds of interesting stuff. Often, we would love to share them with you, and get your thoughts, but they just simply don’t have enough information or aren’t hacks at all. This is where HackaDay Links come in. Occasionally we’ll gather up some interesting stuff and post it all at once. These probably won’t be hacks, so if you’re not into seeing other interesting stuff, just wait for the next post.

We used to do these posts from time to time, and we’ve decided to start again. Without further adieu, here are the links:

1.Medgadget has a pretty cool crutch system which uses your upper leg for support instead of your arm. Seems like a better way of building support for digitigrade legs to us.

2.VR pods sure are looking funny now days. Seems like you could do this on your own pretty easy with some simple dome projection.

3.We were unaware of The Gadget Show, till we saw this post on DVICE. For those that don’t want to sit through it all, they do two projects. One is a wearable computer jacket with a projector built into the sleeve, the other is a set of iPod controls built into some horribly gaudy high heels. We shouldn’t judge the fashion though, they probably know fashion better than us.

4.These massive robotic arms have been all over the net for the past few weeks. The video is sort of neat, with cool cgi effects, but all he does is wave them around somewhat lethargically. We do hope to see something more soon.

5.Princess Leia, sunbathing. We had to share. Thank us later.

6.You could win [Ben Heck]’s PS3 laptop. Unfortunately you have to spend a bunch of money at the score. Just in case you’re curious, they value it at $7500

Electronic Jewelry

[Ellindsey000] posted this neat little pendant to his flickr stream. We like the way it looks, and the fact that it is a functional circuit. The schematic is even pretty neat. We would maybe wear this, as a belt buckle or something. When we looked at this though, we thought it looked really familiar. Yeah, it kind of looks like the arc reactor from Iron Man, but what we thought of was this cool looking walker. As you could probably already tell, it’s the same person. Great job again [Ellindsey000], and thanks for posting the schemtaic.

Laser Etching Fruit

Ever annoyed by those pesky stickers on your fruit? They never seem to pull off in one piece and they always leave a little glue behind. Well, the industry might be moving away from them in favor of laser etching each piece of fruit. They are using a low energy carbon dioxide laser to etch the skin. The FDA is in the final stages of approval for using this in the states. It is already in use in New Zealand. We might find this a bit weird, but we’ve seen weirder.

Automated Coffee Bean Roaster

We’ve featured several different ways to roast coffee beans over the years. This is the next logical step. [Nightlife31] shows us how to use an Arduino and a popcorn popper to create a fully automated coffee bean roaster. You’ll have to modify your popcorn machine to be controllable. This means installing your temp sensor and relays. You can see a basic schematic for that in the project page. The rest involves making a fairly simple circuit on an Arduino protoboard attachment. The end result is quite nice. We wouldn’t mind waking up to some freshly roasted coffee beans in the morning. We’ve seen these done with PID controls, and directly controlled by a computer. There’s even this one that has a much more involved build with a convection oven mounted on top instead of a popcorn popper.

Mac Mini – Getting A Little More Useful

November 4, 2009 by Jakob Griffith 25 Comments

We’re pretty sure Apple decided to implement an IR sensor in their Mac Mini line simply to mock the user. For those who are unaware, the built in sensor only works with the standard Apple Remote; unless you happen to have a programmable PDA or similar you’re SOL. An alternative solution would be to install a USB IR receiver. But then your beautiful Mac Mini is forced to sit alongside an ugly black box. Why not have the best of both worlds? [SqueeZe] wrote an (almost) entirely non invasive tutorial for placing a USB IR receiver inside his Mac Mini. Reminds us of a certain hack a while back, but the objective was to get the IR receiver outside of the unit rather than inside. Different people, different worlds.

Hack A Day; Into The Future

November 4, 2009 by Caleb Kraft 95 Comments

Through the years, our reader base has grown like we never could have imagined. We thank everyone for reading, and owe our gratitude to all who have sent in submissions. We live for them. The more high quality submissions you send in, the more we’ll post. Along with you, we’ve taken part in some really great projects and enjoyed the writing of some really great people.

Now it is time to share our plans for the future with you. We have two announcements that we would like to get your thoughts on.

#1. Content:

Hack a Day first started as an offshoot of Engadget. It was a place where we were able to look at things from a hacker perspective. Contrary to what some people believe, it wasn’t all hardcore electronic engineering. It wasn’t even all projects. We had fun, and discussed our thoughts on many things that weren’t that complicated.

As we move forward, we will be covering a wide variety of posts. From simple things, like teardowns to the amazingly complex projects that inspire us all. We intend to get you original content from the perspective of people who are not just consumers, but hackers of all different skill levels.

We are working to make it easier to browse the site, with your specific interests in mind. Our first motion was to add the “Classic Hacks” category which gathers up the more complicated projects. We’re open to other ideas of how to best categorize the content to make your experience better.

#2. Social Interaction:

Since the beginning of Hack a Day, we have been inundated with questions and requests. People are asking for help on existing projects as well as trying to break into the complexities that can lay in front of a beginner. We’ve seen unofficial Hack a Day forums come and go, but we think it is time that we did something ourselves. We’ve been working behind the scenes on a really slick system which allows people to ask questions, get answers, and even rate and give feedback.You will hopefully see this appear in a matter of weeks as we finish up the last bits.

We look forward to seeing some of you shine, sharing your knowledge with the hacker community.

25 Scariest Experiments

Warning: This video contains actual footage of a severed dog head, kept alive. Watch at your own peril.

[Annalee] over at io9.com has gathered together the 25 scariest science experiments. There are some truly frightening pieces, like the cyborg beetles which we’ve seen before, all the way to silly stuff like the guy who re grew his thumb using pig powder. Next time you’re thinking of admonishing someone for creating a flamethrower, or a super fast scooter, consider for a moment that they’re not burning peoples nasal passages to stop masturbation or creating zombie severed dog heads like the one in the video above.
