The Body of a Tank, the Brain of an Android [Android]

We've come across plenty of robots that were controlled by phones before, but usually those phones were being controlled by human hands. Some California hackers, however, are building bots that put Android to work for their robo-brainpower.

Their first creation, the TruckBot, uses a HTC G1 as a brain and has a chassis that they made for $30 in parts. It's not too advanced yet—it can use the phone's compass to head in a particular direction—but they're working on incorporating the bot more fully with the phone and the Android software. Some ideas they're kicking around that wouldn't be possible with a dinky Arduino brain: face and voice recognition and location awareness.

If you're interested in putting together a Cellbot of your own—can you even conceive of a cooler dock for your Android phone?—the team's development blog has some more information. The possibilities here are manifold; mad scientists, feel free to share your Android-bot schemes in the comments. [Wired]

Diffus pollution dress is turned on by CO2, prefers a clean environment
We've seen LED-laced dresses before -- though sometimes we'd rather we hadn't -- but this one here is almost refined enough for us to consider wearing. Stitched together using conductive embroidery, hundreds of LEDs are connected to a CO2 detector and react to its input with anything from a slow pulsating glow to a blinking signal of doom. No mention of Morse code messages, unfortunately, but this is run by an Arduino chip -- which means programming malleability (read: near-limitless possibilities) should be built in. Just know that when you see the next Bond girl communicating with Daniel Craig via her haute tech outfit, we had the idea first. A closeup of the dress and processor awaits after the break.

Puck makes any surface interactive, probably even Surface (video)
Ask any home audio enthusiast and they'll tell you: there's nothing quite like precisely adjusting settings via an giant knob. However, they can't all be huge or our living rooms would be covered by the things. Enter the Puck: a wireless RFID reader that also contains an accelerometer, controlled by an Arduino Mini and created by Eric Gradman along with Tyler and Brent Bushnell. RFIDs mounted to walls or other surfaces tell the PUCK what function to to control, and then the accelerometer serves to increase or decrease the value as it's turned, truly turning it into a virtual knob. If you're done snickering, there's a video after the break showing one Puck controlling three separate light colors individually, perfect for dialing in the perfect mood or concert lighting -- if only it could dial down the amplitude of dude's fauxhawk.

Pong Prom: When a Man and a Woman Play Body Pong in the Dark [Art]

The only thing geekier than slow dancing at arms length apart is Pong Prom. Covert Athletics' hoodies are embedded with arduino controlled LEDs that display a game of pong. The controller? Your dance partner's swaying hips, monitored by accelerometer.

It is safe to assume that as the speed of the game goes up, you're required to switch your listening from rock ballad to punk. [Like it Cool]

‘Princess and the Pea’ Alarm Clock Makes It Impossible to Stay in Bed [Alarm Clock]

This homemade "Princess and the Pea" alarm clock is hooked up to a compressor that will literally toss you out of bed if you hit the snooze button. Not exactly subtle, but it sure is effective. [ProjectPage via Make]

I’m Building This DIY Batsignal and Then Taking You Jokers Down [DIY]

I was never sure if Batgirl had a Batsignal, but it doesn't really matter. I'm gonna build my own using Arduino, some LEDs, and these instructions anyway. And then I'll track down a slinky costume and take down some troublemakers.

You can find all the details for Batsignal projector (including stencil patterns) at Thingiverse. Fun part is that you can even switch out the stencils just in case you decide that you want a different superhero identity. Spacegirl-signal, anyone? [Thingiverse via Make]

DIY Laptop Etch-A-Sketch is Almost Worth Destroying a Hard Drive [DIY]

I think my hard drive flinched in fear when I pulled up these instructions for turning a laptop into an Etch-A-Sketch. How could it not when the project is a freakin' awesome Arduino-powered Hack-A-Sketch that you actually shake to erase.

The shake-to-erase action works because of a hidden mercury switch which detects movement and you don't really need to worry about the hard drive since this project kinda destroys your screen. [Project Lab via Make]

Hands-On Gifts for Hackers, Makers and the DIY Obsessed [Gift Guide]

Hi there, I'm Phil. I live in an electronics factory, and regularly need to pluck microcontrollers out of my feet when walking around barefoot. I thought I could bring some of that joy to you in a gift guide.

It's going to be a little different than just the usual crap you can buy—it's a guide that can start you on an amazing journey of building electronics, learning new skills. If you're really motivated, you just might invent something new.

Let's get started! The question I get asked the most is "where to start"—lots of people see all the DIY projects here on Gizmodo and just don't know where to begin. I've put together some favorite tools, resources and beginner electronics kits that will get you going and give you something fun to show your friends. You don't need to buy many things either, since many of the kits and gadgets are "open source"—you can buy the parts, etch a circuit board, "breadboard" it or in some cases just build parts of them with what you may have at home by cannibalizing a junk drawer of fail-gadgets.

BTW, if you hate the gallery format as much as the Grinch hated Christmas, click here.

The Tools

Starting out on your electronics adventure? Want to wield the mighty soldering iron? Tired of saying "I'd totally get into electronics if I only knew what tools to get..."? Working with substandard equipment is a terrible way to learn electronics: A lot of frustration with too little success. The right tool set will keep you progressing without the stressing. This toolbox contains carefully selected hand tools that will last you for many many years. Keep in mind that you don't need to buy this tool pack—just look it over (itemized on the product page). Consider it a list of good things to have to get started. You may even have some of these tool collecting dust in the garage already! $100 [Ladyada's Electronics Toolkit]

Make & Build Stuff

Now that you've got the tools, what's next? Microcontrollers! These are basically cheap, tiny computers that you can run simple programs on, control motors and make stuff happen based on sensor data.

For the longest time BASIC Stamp/PIC was the dominant chip that hobbyists used, and still to this day PICs are very popular. However, over the last few years an open-source project from Italy called "Arduino"—named after the Italian king Arduino of Ivrea, who ruled from 1002 to 1015, of course!—it has captured the hearts and minds of many beginners. No one knows why it's so popular (over 100k units!) but I'd say it's because the software to program them runs on Mac, PC and Linux, there's a huge community of artists who make amazing things and share them, and it's pretty inexpensive. And since it's 100% open source, you can make your own versions, improve on them and sell them if you wanted to.

What do the following projects all have in common? Google Street View on a hacked stationary bike, electronic wallpaper, secret-knock door opener, Ghostbusters proton packs, Barbots, skateboard etch-a-sketch and a Twitter toilet that tweets your poo... They're all made with Arduino!

Make & Build Stuff

You don't need to buy an Arduino, you can "make" one using a breadboard and a lot of parts—but let's say you want to dive in and pick up an Arduino with enough projects to teach you how things work, and help you explore microcontroller basics. Covers LEDs, transistors, motors, integrated circuits, pushbuttons, variable resistors, photo resistors, temperature sensors & relays. I suggest the Arduino ARDX experimentation pack for $85. If that breaks the bank, choose from less expensive packs: a $65 starter pack, a $50 budget pack or just a straight-up $30 Arduino.

If you can scrounge up the parts on your own you can always download and print up the free booklet which includes all the lessons. If you're the book-learnin' type, there's a great little one called Getting Started With Arduino, $13, written by Massimo Banzi, co-founder of the Arduino Project.

Make & Build Stuff

The Arduino is great and there are a lot of "shields" to expand its functionality (music, GPS, internet), but what if you want to get your hands dirty and make something more complicated? Here are three of my favorite beginner electronics kits to get you started—as always, they are open source so you could make these on your own too.

The first lets you juice up all the gadgets—MP3 player, camera, cell phone, etc.—that you plug into a USB port to charge. The Minty Boost is small and simple but very powerful. If you have a new or old phone that always runs down, make one of these to get a lot of extra talk time. Be sure to check the project page for the latest compatibility notes for many devices. $20 [Minty Boost kit]

Make & Build Stuff

Relive the fun of CES 2008 everyday with TV-B-Gone. People are still polarized about the whole CES thing. Everyone was complaining that CES sucked because it was just about "giant TVs" and when someone turned them off for a few seconds the intarwebs world freaked out. I don't have any opinion on it, other than that CES should be more exciting than a TV-turn-off freak out. That said, the TV-B-Gone is a wonderful device to learn the ins-and-outs of IR signaling, and it's fun to turn off TVs in store windows that are closed at night to save power. (That's what I like to do.) The new Universal TV-B-Gone kit is an ultra-high-power version of the TV-B-Gone (assembled), able to reach 150 feet and can be used anywhere in the world. Plus, you make it yourself. $20 [TV-B-Gone (kit or assembled)]

Make & Build Stuff

Spell words in the air with your bicycle wheels using SpokePOV, an easy-to-make electronic kit toy. The project includes a free schematic design and open software for uploading and editing stored bitmap images. Perfect for those late-night Critical Mass rides or your Burning Man transport. $100 for triple; $38 for one [SpokePOV]

Hackable Electronics and 3D Printing

Next up, I put together some of my favorite "gadgets" that aren't necessarily kits but are hackable. Many companies are inviting their customers to hack and mod their devices, the folks are the pioneers!

The Chumby does so many things it's hard to actually tell someone what it is. I usually say it's an internet alarm clock that runs widgets. Most people seem to get that, or they'll get curious enough to check out the site. The latest version, the cool retro-looking Chumby One is out. The product is open source, so you can hack it, mod it, get the source and schematics and best of all make widgets for it. (Chumby trivia: The engineer behind it, Bunnie Huang, is one of the best engineers in the world. If you're old school, you'll remember him as the first person to hack the original Xbox, and as author of Hacking the Xbox: An Introduction to Reverse Engineering.) $99 [Chumby; Review]

Hackable Electronics and 3D Printing

Bug is the Lego of computers. Make a GPS camera MP3 player? You can! It's a modular, open-source system for building whatever comes to mind, by plugging little modules into each other till you get the desired functionality. If you want to program them, you need to know Java, but there are also a lot of apps you can just download. BUGbase core $450; assorted modules from $70; monster kit $750 [Bug Labs]

Hackable Electronics and 3D Printing

MakerBot is a new entry in the world of 3D printing. Based on the open-source RepRap project, Brooklyn-based MakerBot is becoming the default install for any self-respecting hacker space. (Well, that and a laser cutter.) The MakerBot can print 3D objects you make or download—Thingiverse is a great source. The coolest thing I've seen lately is a print out of Thom Yorke's head. $700 [MakerBot]

My Fantasy Gadget

The Giz gang asked me to name a "dream gadget," and of course for me it's something that makes things: A "pick-and-place" machine, namely the MDC 7722fv from Japan. You could use it to make iPhones in your living room if you really wanted to. I have one now, so at least for me, the fantasy has became a reality. I'm currently making accelerometers and Drawdios (musical pencils) but next year expect to see an open-source watch and who knows? Maybe you'll see me selling cloned iPhones on Canal Street in NYC, next to the counterfeit DVD and purse dudes. Over $30,000 [MDC; US distributor]

Got questions or comments? Post 'em up below. I'll try to answer all of them that I can!

Phil Torrone is the senior editor at MAKE magazine and creative director for Adafruit Industries, an open source hardware manufacturer in NYC. In the interest of disclosure, please note that many of the products you see above are sold though Adafruit and Make, but it just so happens, the source for the best info is also the source for many of the goods.

All Giz Wants is our annual round-up of favorite gift ideas, including amazing attainable objects and a few far-out fantasies. We'll be popping guides catered to different interests several times per day for the next week, so keep checking back.

Take a Virtual Tour Through Google Street View On a Stationary Bike [DIY]

Using a Vuzix headset, a laptop, Arduino and a bike sensor, Aki Mimoto was able to rig up his wife's stationary bike to transport himself through a virtual Google Street View environment.

Of course, that means you wouldn't have to sit staring at a wall or a TV while exercising—you could virtually travel down roads anywhere in the world. Unfortunately, the design needs some tinkering to be really usable—but it's a fantastic concept that's really worth pursuing. If there was a commercial product that got this right, I would probably be all over it. Hit the following link to learn how to do something like this at home. [Bako via Make]
