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.
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
Oh, for crying out loud! While we were all giddy reporting on yesterday’s wonderfully done head-mounted computer, [Andrew Lim] of recombu.com comes along and essentially does the same thing with an HTC Magic handset and three dollars worth of Harbor Freight crap. Linux kernel, WiFi, accelerometer, the whole nine yards. Consider our collective ass handed to us.
Funny thing is, either of these could be considered The Consummate Hack. One flaunting the creator’s know-how with its custom-designed parts and delicate engineering, the other exhibiting a more punk flair with random scraps and off-the-shelf technology achieving much the same effect — a solution so obvious we were blind to it. Whatever your outlook, this is a great day to be a hacker!
[GuySoft] sent in this project. He doesn’t normally mess with electronics, but decided to give it a try. He chose a fairly complicated project to be his first, but seems extremely comfortable with it. This project was to control his R/C car with a pic16f84. That chip was chosen simply because it was the only one available at local stores. Though we’ve seen much more complicated projects in the past, he does a great job of showing exactly what has been done. He shares his thoughts and source code with us as well. He has express a little frustration about the closed source compiler he was using, so if anyone has any suggestions for him, he would probably appreciate it. The funny part is that he mentions that people would just tell him to “get an AVR”. We think the readers here will probably be happy with how he pulled it off.
Facebook’s internal valuation was revealed this week thanks to shoddy PDF redaction. Court documents from a settlement between Facebook and ConnectU showed that Facebook values itself at $3.7 billion, much less than the $15 billion that was speculated during the Microsoft investment. The AP uncovered this by cutting and pasting from the redacted court document. It’s the same thing we showed in our PDF redaction screencast last summer… and it will never cease to be funny.
We’re happy to present this guest post from History Hacker’s [Bre Pettis]. Today [Bre] catches up with the Blinkenlights team, who turn entire buildings into displays. Their current project is Stereoscope which goes live in Toronto, Canada today.
Earlier this week, I posted about the beginnings of the blinkenlights project. It started in 2001 in Berlin, but now Seven years later, in May 2008, blinkenlights is back. The City of Toronto asked the blinkenlights team if they would be interested in joining another Nuit Blanche (as they did in Paris in 2002). Short on time and with a lot of ambition, they decided to redesign and push the envelope on the project to make it wireless for The Toronto City Hall since there would be 960 windows split up in two towers. In the above photo, you can see Stereoscope in all its glory. Read the rest of this entry »
[funnypolynomial] saw this Pong clock years ago and had been planning on building his own version. With a move looming he decided it was finally time to finish up his Pong clock since completed projects take far less room than incomplete ones. The core of the system is a ThinkPad. He separated the hinge and bolted the keyboard to the back of the screen. The display ribbon was long enough, but he had to extend the wires for the backlight. The power button was also extended and the battery removed. The software is a Windows screen saver that uses the two mouse buttons for navigation similar to how you set a two button watch. Every minute the the left player misses the ball and the right player’s score increases. You can see a video of the clock below. In the past, he also turned a digital multimeter into a clock.

Various cybernetic limb and organ replacements were recently featured in IEEE’s flash demo called The Bionic Body Shop, but we were most interested by the bionic eye and the cochlear implant (we already discussed the featured powered exoskeleton). These are notable for the fact that they are not merely high-tech prosthetic replacements strapped to or worn on the body, but implants that are housed within the body and work with flesh-and-blood sense organs on a much closer level than any preceding technology.
Normally, this wouldn’t quite make my radar, but [sprite_tm] built it, and it’s funny as hell. He created a Terror Level indicator for… his toilet. Rather than create an exotic smell detector, he simply uses a photo diode to measure the amount of time that the light has been on in the ol’ water closet. As time progresses, so does the Terror Level indicator. To make an audible indicator, he used the PWM generator in the ATTiny231to create a sort of ping sound when the level escalates. (I can definitely think of someone I need one of these things for.)
[fbz] wanted to make sure that everyone knows that RFID Guardian has released the latest version of their design. I had a hard time finding a good shot of the hardware, so I went with the Nokia phone control application. There’s a short explanation of the project here. I’d point at the use examples on the site, but it seems that their MYSQL server is running out of memory. After seeing this talk at shmoocon last year, and a bit more reinforcement at defcon, there are definitely some good uses for the guardian. (Once you get past the slow start, Major’s intro is funny as hell. – jump past the first 8 minutes or you’ll be bored.)
Hack-A-Day reader [al cohen] was pretty perturbed by Staple’s Easy Button campaign since nothing in business is easy. So he decided to modify their cute button (PDF). He replaced the guts with a cheap recording circuit from RadioShack. He also added a 1/8 inch jack so you can record directly from the computer. The new button doesn’t need a separate mic either; you can record by speaking into the speaker. As a final touch Al ground off the easy, polished it and made the button evil. You can watch a video of the button declaring his distaste for Spam. You might have seen Jeff Caylor’s previous abuses of the Easy Button on Make. My roommate thought it would be funny if someone wired it to generate the “shift+delete” key sequence.
