‘Secret Knock’ Door Lock defends home from rhythmically-impaired perps (video)

The Arduino board has been the engine of many wild and wacky projects over the years, from bakery tweeting to various musical instruments. For its next trick, our man Steve Hoefer has taken his microcontroller and, along with a piezoelectric speaker, a gear reduction motor, and some PVC pipe, programmed it to listen for a preset sequence of knocks — a secret knock, if you will — and unlock the deadbolt upon hearing the right combination. Although this might not be the security system you want to put in place for your home, this definitely looks like a fun weekend project. Check out the read link for instructions and schematics, but not before you see the video of the thing in action. It’s after the break.

Laziness on the move: robot plays Rock Band on the iPhone


Why confine your nerdy sloth to your living room, where large robots mime fake guitar and serve you sloppy mixed drinks? Take that zest for the sedentary life with you on the road by having one of your robot ninjas steal this iPhone Rock Band robot from its ingenious creator, Joe Bowers. The Arduino-based device uses ambient light sensors to detect the falling notes and then taps out the music with some conductive foam attached to some squeaky fake fingers. Joe did a fairly detailed write-up, and even uploaded his code, so there’s presumably nothing stopping you from actually doing something with your life and building one of these with all that free time you’ve saved up by hacking your way through all the console-based guitar games. Video is after the break.

Football Hero mod takes Arduino to the Kasabian-approved big leagues (video)

Some folks say less is more, but we’ll bet they never saw Guitar Hero being played by kicking footballs against a giant wall. This epic undertaking will give your plastic axe a major inadequacy complex with its huge wall-mounted piezo vibration sensors and absurdly large fretboard projection. An Arduino acts as the conduit between the contact sensors and a PC running the freeware Frets on Fire. The outcome from such a relatively simple setup is pretty astounding, and you can check it out in the videos past the break, including some behind the scenes footage.

Homemade GPS puzzle box puts a modern spin on treasure hunts

We’ll readily admit that most Arduino mods tend to be exercises in creativity (and eccentricity) with little real world utility, which is why this one piqued our interest. A wedding present conceived of and built by Mikal Hart, the box you see above is set to only open in one particular geographic location, and the puzzle of it is to find out where that might be. You’re allowed 50 attempts at opening the box by hitting the button next to the LCD screen, which in turn gives you a distance from, but not direction to, your destination. What tickles us about this idea, aside from its ingenuity, is the potential to use it without the helpful hints in securing your own valuables. Check out the read link for a full shopping list of ingredients and the amusing reaction to the quirky gift.

Robotic ‘mood tail’ is everything you hope it to be, and more


Why hang on to your emotions when you can wag them proudly with a robotic mood tail? Sure, you may never have asked that question yourself, but intrepid DIYer Wei-Chieh Tseng seemingly has, and he’s done something about it. Apparently, the tail makes use of the ever dependable Arduino and an RFID reader to detect different emotion cards that set off varying degrees of tail-wagging, or you can simply control the tail yourself using a Wii nunchuck — because, why not? Did we mention there’s a video? Check it out after the break.

ProtoDojo turns NES controller into flash drive with Konami-level security

The humble NES controller has certainly provided plenty of inspiration for mods over the years, and even a little dreaming, but it doesn’t look like the well is showing any signs of drying up just yet. The latest to take a crack at the iconic gadget is one man shop ProtoDojo, which did what many others have done and turned the controller into a flash drive, but went the extra step of adding an ingenious security measure to ensure that only true NES veterans are able to mount the drive. We won’t spell it out here, but let’s just say this drive stands a better chance at Contra than most — all possible thanks to the magic of Arduino, as you might have guessed. Head on past the break for a complete overview on video.

Adafruit’s DIY ‘less lethal’ weapon looks cool, doesn’t really work

As you’re no doubt well aware, the government is always looking for new ways to make dissidents feel uncomfortable. In this space alone we’ve seen devices meant to cook folks with microwaves, zap ’em with electricity, and make ’em nauseous using light. Taking inspiration from the last one, the open source pranksters at Adafruit Industries have built a contraption of their own called the Bedazzler. It’s powered by an Arduino and, unlike the original, Adafruit’s version doesn’t seem to work for the purpose incapacitating no-goodniks — but that’s probably a good thing. For some background on this extremely less than lethal device, peep the the video after the break. And then hit the read link to build one yourself.

N900 hacked to replace the innards of a Speak & Spell, can never bring back your childhood

Nokia has been handing out the N900 for selective “artsy” uses lately through its “Push” program, and the folks at Tinker it now! sure seem to have put their model to good use. They’ve paired the device with all matter of nostalgia, including a Rolodex, FM radio and a 3D Viewmaster. Our favorite by far, however, is the Speak & Spell hack, which puts the gargantuan Speak & Spell keyboard to good use in penning text messages for the N900 — which displays them in the classic font and even articulates your words with a speech synthesis engine. It’s all a testament to the flexibility of Linux, hacker ingenuity and of course liberal application of Arduino, but it’s also a little advertorial-ey, so you might want to leave your gag reflex at home for this one.

TRKBRD surface touchpad puts your weekend DIY project to shame, probably

It may not seem like much from this video, but Malmö University graduate student Rob Nero has assembled himself a surface-based touchpad using all Arduino products and “simple Algebra.” Dubbed TRKBRD, the device uses hyper-fast flashing LEDs and IR sensors to calculate the XY coordinates of the shadow, and subsequently the finger itself. We haven’t seen it hooked up to a computer just yet, but we hope there’s more to come. Videos of the successful trial run and some preliminary testing and wiring after the break.

Arduino binary clock doesn’t care to be useful, just wants to be admired

If there’s one thing we love about DIY projects, it’s the feeling that the outcome is more than the mere sum of its parts. This here binary clock is a prime example, being composed of scrap plastic, some dirt-cheap parts and a homemade Arduino board. And yet, after a few licks of polish and the inevitable LEDs, it looks like a true monument to geekdom, which is only amplified by the fact you can’t even use the thing without being familiar with binary code. But then again, if utility was a standard by which we judged homebrewed projects, we’d have a lot less to talk about.
