DIY Friday: Charge Your iPhone With AAs or Solar Power

Limor Fried’s MintyBoost project is a great example of DIY and commercial tech working together. Take an Altoids tin, a couple of AA batteries, and some very smart hackery, and you’ve got a lightweight USB charger that you can use to charge/run your handheld iWhatever, or almost any other phone, camera, or small device that can take a charge off USB power. About a month ago, she released this video outlining the Apple hackery needed to make this work.

Clive Thompson profiled Fried and her company Adafruit Industries as part of a 2008 feature in Wired on “open source hardware.” The idea is that hackers like Fried can use what they find out about consumer devices to make and sell their own products, but also to produce DIY kits and share information with others who then build their own projects.

As a case study in the value of sharing this information, consider Rob Scott. Before he took his son on a week-long bike trip this summer, he used Fried’s schematic to hack together what turns out to be a really striking-looking solar charger for his son’s iPod.

It’s always nice to see what the maker community is doing to accessorize their retail gadgets; the results aren’t always super-polished, but they generally solve real problems in important use cases that don’t get addressed by manufacturers, either because they’re too unusual or they can’t be easily solved by more plugs, more peripherals, more complex devices that cost a lot of money. And in turn, we all find out a little bit more about how these magical devices get put together and how they work.

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.
