] | Looks like they’re at it again over at Adafruit. This time they’ve
produced a clock
that looks more like it should be attached to a munition rather than cruising bedside. But, geek-cred aside, there’s a lot to be learned from their design. Like we’ve grown to expect, they’ve put together some good documentation on their choice of components.
Start off by
taking a peek
at their 5v power regulator. There is an extra diode on the output side that prevents reverse current from the 3v backup battery. The AVR ATmega168 that controls the clock is used to detect loss of power and quickly shift to the battery backup. They’ve also used the microcontroller as a boost converter for the high voltage VFD, a nice trick
we’ve seen before
.

With a price point of about $100, it’s strange that the device hasn’t made more of a stir in the consumer electronics market. Of course, if it exists, someone will hack it, though. Clever hardware and software hackers have already managed to get an
alternative firmware
running on the device, allowing for packages like a
web server

RSS reader
,
Apple trailer viewer
, and
other linux-based packages
. It’s good to see a device with so many software mods so early into production.

"arora",

"netbook",

"webkit"
] | With
netbooks
being slim and mostly utilitarian, it seems a bit contradictory to use a standard and somewhat bulky web browser with them. After all, we’re
trimming
down
the operating system to perform faster on these little devices, so why not thin out the focal point of the netbook: the browser. Firefox, Chrome, or Safari may be well and great for a full powered desktop or laptop, so how about something a bit more trimmed? Enter the lightweight Webkit based browsers:
Arora
and
Midori
.
Arora and Midori are relative newcomers to the browser wars, but each offers a great alternative to Firefox, especially for netbooks. They’re both based on the opensource Webkit project, which is the same engine used by Chrome and Safari, so pages load quickly. Flash is supported and fully enabled in both with video playback working just as well as other browsers. The main advantage is the loading speed of the browser itself. On an ASUS Eee PC with Ubuntu, Firefox takes a few seconds to load, where Arora and Midori load in under a second.
These projects are maturing pretty quickly, and some great features come out with each version. For our money though, Arora takes the cake, and has replaced Firefox as my browser of choice for my netbook. It’s quicker, offers a somewhat similar feature to Firefox’s “awesome bar”, has a privacy mode, and is generally a little bit faster than Midori. | 12 | 12 | [

"arduino",
"arm",
"arm7",
"atmega",
"cortex",
"maple",
"stm32"
] | The Atmega168 at the heart of every Arduino is an eminently capable chip; its ilk have been seen working as a basic
web server
, playing back
digital audio
, even generating
TV signals
. But as projects continue to grow in sophistication, reality rears its ugly head: Arduino can handle any
one
of these tasks very well, but it often requires squeezing every last instruction cycle or bit of memory in the device. Even the ’368 chip and the Arduino Mega are stopgap measures. Sooner or later, you have to graduate to long trousers—move up to a more capable microcontroller platform—an uncomfortable change usually involving a hefty investment in new hardware and an intimidating learning curve. Leaf Labs’
Maple
aims to change all that…
Maple, expected to ship in October for about $40, brings together the
STM32 microcontroller
, a 32-bit 72MHz beast of a chip, with the familiar Arduino footprint and even compatible library functions. Users can jump right in, preserving their existing investment in Arduino shields and know-how, then expand their repertoire with the new capabilities afforded by this beefier processor.
But Maple is not the first. Coridium Corporation’s $30
ARMite PRO
(below) is a 60MHz ARM7 board that’s pin- and footprint-compatible with Arduino Pro. The CPU isn’t quite as powerful as the STM32, nor do they provide Arduino-compatible libraries, but it’s still a significant step up from the Atmega and is available
today.
Also worth mentioning, though it lies in an entirely different direction, is Raisonance’s
STM32 Primer
(also called the STM32 Circle), shown below. This kit is neither hardware- nor software-compatible with Arduino, and the bundled software tools are Windows-only, but it’s similarly affordable (about $40), self-contained (no external programmer), and will give you a head start with the STM32 chip
right now.
And while you can’t bring your Arduino shields to this party, the Primer brings its own fun: a color LCD, 3D accelerometer, and rechargeable battery. The original “Circle” Primer is a little tricky to track down, but a little Google searching can help here. A “Primer 2” with more features has since been released, if you don’t mind paying half again as much.
Maple is just the first of several increasingly powerful Leaf Labs projects that are planned. FPGAs and gigahertz-speed CPUs are in the pipeline. | 23 | 23 | [

Burning Man

The primary flames consist of 41 “poofers” along the spine of the serpent each one capable of delivering a 8′ tall flame. Tucked away near the tail is a egg that makes use of methanol and boric acid to create a massive green fireball. When the egg is open nobody is allowed with 150′ of the project. The brain that runs the beast is nothing more than a RS-485 network of humble ATmega8s. The microcontrollers are wired with XLR cable and chatting at a 19200 baud. Max/MSP is used on a laptop to control flame patterns. Here is a enjoyable
write-up
and
video
. We particularly enjoy the bit about the strange looks the team got when purchasing 50 stun guns. | 12 | 12 | [

SheevaPlug
plug-in PC being released alongside its consumer solution counterparts. One of the prominent products based on the SheevaPlug hardware is the
Pogoplug
. The Pogoplug is essentially a no-configuration media server that allows you to plug in a hard drive and network cable to make data readily available anywhere you have Internet access. It’s a great idea, but the underlying software is closed source, limiting the demographic of the device to consumers who are happy with an out-of-the-box solution. Enter
OpenPogo
, a solution for people who want a bit more control over their device. OpenPogo gives users more say over what their Pogoplug does; from running a
torrent client
to a
web server
to a
Ruby on Rails server
. The possibilities for the device are limitless, and OpenPogo makes turning our ideas into reality it just that much easier. | 21 | 21 | [

Most often seen in security floodlights and automatic doors, in creative hands these sensors can be put to other uses—cat flaps, camera triggers and purely artistic applications—as you’ll see in several demo projects and videos. For the curious, the tutorial provides a good amount of background theory on how PIR sensors work, along with the associated fresnel lens optics. And for those who just want to get hacking, most PIR sensors (like the one above) come in a simple-to-interface module containing all the support hardware and providing a simple digital output; the article wraps up with one such example. | 18 | 16 | [

Swedish hacker [Hans Andersson] is no stranger to puzzle-solving robots. His prior work, A Rubik’s cube-solving robot called
Tilted Twister
, made waves through the internet last year. [Hans’]
latest project
only has to work in two dimensions, but is no less clever. This new robot, built around the
LEGO Mindstorms NXT
system, “reads” a printed sudoku page, solves the puzzle, then fills out the solution right on the same page, confidently and in ink. It’s a well-rounded project that brings together an unexpected image scanner, image processing algorithms, and precise motor control, all using standard NXT elements.
The building instructions have not yet been posted, but if the video above and the directions for his prior ’bot are any indication, then we’re in for a treat; he simply has a knack for explaining things concisely and with visual clarity. The source code and the detailed PDF diagrams for Tilted Twister are as gorgeous as his new robot’s penmanship.

Robot enthusiast [Vitalijus Rodnovas] built this rig to allow a humanoid robot to mimic his own body movements in real time. [Rodonovas] refers to his man-machine interface as a “master-slave suit,” but elsewhere this is often called a
waldo
after a prescient 1942 [Robert Heinlein] novella. This
project page
is slight on details and is mostly written in his native Lithuanian, but the pictures speak volumes, and with a little help from Google Translate we can learn the essential facts: The robot itself is a commercially-available kit, the
Kondo KHR-1HV
from Japan. The custom-built harness uses a collection of surplus Soviet-era military potentiometers (acquired on eBay) to read the positions of his elbows and shoulders, then an ATmega8-based interface board translates these readings into motion commands sent to the robot’s onboard controller. Some additional notes and code can be found on the
RoboSavvy Forum
.
Does it work? Just watch. His grin as the video progresses is infectious!

In what seems like another move to blur the line between digital and print media, CBS has announced that they will be introducing something called
Video-in-Print technology
in next month’s issue of Entertainment Weekly. Video-in-Print, or ViP, technology consists of a small LCD screen and circuit board that can be inserted into print media and play video and audio content. CBS is using the ViP technology to promote their fall prime-time television lineup. Video-in-Print technology is the brainchild of
Americhip
, a company that claims to specialize in multisensory marketing. The ViP player in next month’s issue of Entertainment Weekly incorporates a 320×240 resolution TFT LCD screen and a rechargeable battery lasting 50-60 hours. The battery can be recharged via the player’s on-board mini USB port. While this isn’t the
first time
that we’ve seen a magazine do something like this, as far as we know this is the first time that anyone has put a video player into a magazine. That being said, there seems to be no indication whether or not CBS will make it easy for us to modify the ViP player’s software like Esquire did with their
e-ink display
. We’re not entirely sure what we’re going to do with the ViP player, but the fact that it has a mini USB port gives us some interesting ideas.

Handbot
is one piece of a larger project called Swarmanoid. The aim of the swarmanoid is to replicate the functions we usually desire out of a humanoid bot with a whole swarm of specialized bots. That seems like a silly goal to us, considering the only requirement for a humanoid bot is that it be shaped like a human. That aside, we like their stuff. The handbot specifically is designed to retrieve books from bookshelves. It has specialized arms for climbing and grabbing the books with a batman-esque retractable rope launcher mounted on top for added speed and strength. The gait of the handbot really reminds us of how
chameleons walk
. We’re curious if this is a coincidence or not.

He pulled the brains from the clock and replaced them with an Arduino. He then runs a program that updates the Arduino based off of the system clock. He has also added an internal clock to maintain the settings so constant updates are not required. It would have been nice to retain manual functions via the remote so you could press a button for a full moon without having to change your system time.

It is noted that in a pinch it may be torn down with a pair of pliers and washer; in place of a flat head screw driver.

was used to simulate usage. Though it isn’t much of a robot, consisting mainly of simple pneumatics, it does serve its purpose. The study was able to determine the most common cause of breakage, and hopefully this information will lead to less occurrences.
Robots do exist
in the sex industry, and not just in that speculative future sex bot sense. Why weren’t any bots of a sexual background included in the

The case is hand-crafted, (no laser cutter!) no-frills box made of painted polycarbonate, and man is it sexy. It is built off of a v1.4 motherboard running a third-party BIOS and with a 320GB laptop hard drive. Load up

One of the most impressive features of the kit is the fact that the new TV-B-Gone is universal and can now work in Europe and Asia in addition to the US. Users are able to select which region they want to use during the build process by soldering a resistor into the board at their region’s corresponding spot as seen in the picture above.

This is the Happillow

While pillows exist that are supposed to cut down on snoring, they generally have a specific shape to position your head properly, which should cut down on the snores. [Harandi] points out that this might be embarrassing to the user as it is obvious to anyone looking at the bed that they have a snore reducing pillow.

A delta robot usually has 3 arms connected to a single point at the end. This configuration allows the end point to maintain its “level” while the whole unit is moved, usually very quickly. There are a few people building them in this forum. The one pictured above is [Asurofilmchen]’s version, but you should also check out [Radbruch]’s posts of a robot made by [Jamison].

His solution wasn’t to simply buy a scale that could be hooked to the computer. Those are available and aren’t really that expensive. He could have even used pencil and paper to chart it in a few seconds. Instead,
[Jorge] started hacking
. He took apart a digital scale he already had and installed his own circuit to display weight and write the values to a CSV. The CSV resides on a removable card which can then be put in his computer to chart the data in
openoffice

[Dennis] tipped us off to his
Tome project
. It looks like two projects using very similar hardware. The first is the Tome GS; a tiny game system that looks like it could hang from a keychain. This is apparently the second revision of this system, based off of some of his comments. He’s done a pretty good job, it looks solid and functional. It even includes a zigbee wireless module for communication with others. He states that the graphics should be roughly the same as a gameboy advance. The second is the Tome MP, a portable media player roughly the same size as a first gen iPod nano. It is equipped with bluetooth, though he’ll be removing that in the next iteration in favor of a zigbee. We would really love to see more information on the design behind these projects. | 10 | 10 | [

getting a really even toner transfer
when making your own PCBs. First, the PCB is cut to size, and the paper is tacked to the board. Then, the PCB is placed paper up onto a dowel and rolled back and forth with the iron. Since the board bends slightly over the dowel the toner sticks evenly to the copper. After that, just remove the paper as usual and
etch with your preferred method

The director’s cut of the story
While coverage of the
official Defcon badge
has been pretty heavy, there was a badge that was far more exclusive and talked about way more. For the last ten years at Defcon a group of hackers known as
Ninja Networks
hosted an invitation-only party for selected attendees. For the 2009 event, [cstone] and [w0z] created an electronic badge which acted as the ticket to the party. The badge is based around an 8-bit Freescale microcontroller (MC9S08QE8) which drives 10 individual 16-segment HIOX-format LED displays.
The custom PCBs were manufactured by 4pcb, but all other assembly was done by hand with a huge team of volunteers in Boston, Los Angeles, and Las Vegas. Assembly space for this effort was provided by
Redwire
and Angel Valley Media. More than 500 badges were created. To help fund the effort, the Ninjas took on internet privacy company
XeroBank
as an event sponsor.
The assembly process is detailed in the video below which highlights a few interesting DIY techniques including using a $30 Target hotplate as a reflow oven.
[vimeo 5981950]
Once assembled, the default mode for the badge is to randomly cycle each display through a list of characters locking in each one to finally display “NINJA PARTY”, in the same manner seen in the film “WarGames”. The badge also has a “Simon” game mode, the ability to view the badge’s unique identifier and sponsor URL, and a fully functional debugger.
Using the debugger a user can reprogram the badge to display different messages, or change it’s functionality with no computer required. This is demoed in the video below.
[youtube=http://www.youtube.com/watch?v=K3TY38k0PA8]
While all the badges were distributed at Defcon 17, [cstone] has provided the
schematics and gerbers
, public domain
source code
, and the
BOM
in case you wish to create your own. We were some of the many people to help hand assemble these badges, which you can find
listed on his site
.

AVR projects
, but this one’s pretty cool.
AVGA
is a color video game development platform based on the Atmel AVR family of microcontrollers. As seen in the picture above, one of the AVRs that the project uses is the popular ATMega168. There were several technical hurdles to using the AVRs to run color video games; one of the most difficult problems was figuring out a way to display detailed graphics from AVRs limited onboard RAM. Eventually, the developers figured out a way to display detailed graphics using a TILE-based driver. The TILE driver works by dividing the screen into X and Y coordinates, dividing the graphics into tiles. Then, when a graphic is needed it’s addressed from a reference table that’s stored in the AVR’s onboard RAM, allowing the bitmap graphic to be loaded from a game’s ROM. Currently, the only games available for the platform are a Super Mario clone, a Pacman clone, and a Snake clone. While there are only a few games available, the platform definitely looks promising. If anything, this project serves as a great example for what off the shelf microcontrollers are capable of. | 16 | 16 | [

According to the video,
Ecce Robot is a new paradigm in robotics
. We don’t know if that’s true or not, but we really enjoy the drive system. They have mimicked the biological structures in humans using elastic cables and cheap drill motors as muscles. It is intriguing to watch the complexity that even a simple arm lift requires. This does show inefficient this type of set up is, but we still think it is cool. We don’t understand the desire to use cheap drill motors though. Cost aside, the control problem they mention seems like it could be resolved with a little better motor setup. Then again, we’re sure they thought of that. This seems like a perfect time to bring up a common question. Is it worth the inefficiency of trying to mimic our natural biological structures with hobby robotics pieces? What technology would have to be present to make it worth the complexity?

All it did was blink
, but it raised the bar for what was expected from a hacker conference badge. In 2007, they went from 2 LEDs to
95 in a scrolling marquee
. Along with a POV mode, the badge had two capacitive switches to let the user edit the displayed text. Defcon 16’s badge featured an
IR transmitter and receiver
for transferring files from an SD card. It worked as a TV-B-Gone and had pads to access a USB bootloader. That was the same year that The Last Hope debuted their
RFID tracking badges
.
This year the official Defcon badge
reacted to sound
, but they were no longer the only game in town. Ninja Networks brought their
10 character party badges with a built in debugger
. The Arduino compatible
HackTheBadge 1.0
also made an appearance. With these new entrants into the field, we wondered what you’d want to see in your ideal badge. What badge would you want to see at next year’s Defcon? Leave you comments below and keep in mind that it should be an idea that is easy to cheaply mass produce.

MIT’s Transology
and designed the
OmniDirectional Research Platform (ODRi)
. There’s a video of it embedded above. It can be driven using three different input styles: an accelerometer joystick, a traditional gamepad, or body mass shift. They started with an Arduino, but needed more I/O and had to switch to a Wiring board (this was before the Mega). The platform is built mostly from scrap. The accelerometers were placed in an old Microsoft Sidwinder. The standard joystick is from a Sega Mega Drive. The weight sensors are out of cheap home scales. | 11 | 11 | [

sniffing out the baud rate
using an ATtiny2313 and FT232 breakout board. The firmware assumes 8 data bits, no parity, and 1 stop bit (8N1). This is pretty much defacto among serial ports so it should work well, though some devices do use different settings. The auto detection routine can sniff rates as low as 110 baud and supports non standard rates. Released under GPLv3, the
software is also supplied in hex format
. [Sprite_tm] has provided great project in past such as
Working with VFDs
,
Controllable bristlebot
, and
AVR boost converter
. Additional information regarding serial hacking after the break.
A great deal of electronics have an Achilles’ heel, known as a serial port. These embedded ports are often used during development to debug functions, load and upgrade firmware etc. At the very least circuit traces are generally brought out for automated testing purposes. Looking up chip pin outs and tracing circuits is one small step in serial hacking. After the traces are known the voltage level is then determined(CMOS,TTL,RS232,etc). Then a few tests are run on the port. These tests generally give indications regarding the potential of the port(does it have a driver, does it have a protocol, what is the baud, etc). If information regarding the baud and other criteria can not be found in the data sheet, [Sprite_tm]’s method would certainly save a great deal of tedious time. Some controllers, like the 68HCxx may have a boot ROM which eliminates most of the guess work in setting up the serial port. We use the
Null-modem emulator
project (com0com) almost daily to help sort various serial problems. This is highly recommended, for anyone spending a considerable amount of time with serial devices. | 19 | 19 | [

"The Manga Guide to Electricity"
] | “The Manga Guide to Electricity”
, part of “The Manga Guide” series by No Starch Press, is a novel approach to the old problem of getting over the initial mental block when trying to learn electronics.
We decided to compare this book to another introductory text:
“Getting Started in Electronics” by [Forrest M. Mims]
. [Mims]’ book is a handwritten masterpiece of electronic literature. The writing style is friendly and concise, the examples are simple, and the drawings are excellent. It also makes sure to keep the learning process as application based as possible. Unlike other books, it doesn’t bog the reader down with math and theory that is only useful to advanced students. Since its original printing in 1983, [Mims]’ has become the de facto standard for beginner electronic literature.
“The Manga Guide” attempts to walk the beginner through the very basics of electronics using the interactions between [Rereko], a resident of planet Electopia; [Yonosuke], a transdimensional robot cell phone; and [Hikaru Yano Sensei], an electrical engineering researcher at a Japanese university. [Rereko] is apparently very bad at electricity, and is sent to learn the basics from Hikaru over the summer by her professor.
“The Manga Guide” is a lot of fun to read. The interactions between the characters are lighthearted, and the whole setting has a sort of quirkiness about it that makes you keep reading just for the joy of it. It covers most of the basics thoroughly and with excellent examples. The art is a very well drawn, playful style of manga.
Unfortunately, in order to keep the story going, a lot of little but important details were left out of the manga. To compensate for this, there are mini chapters of what can be politely described as some of the most dry electronics text ever written. We found ourselves skipping over this text often to get back to the manga parts of the book. Another disadvantage to this book is that it is hard to go back to previous pages in order to reference things since one subject may be spread across several pages of story. This is just an unfortunate side effect of the manga format. A book like [Mims]’ has the advantage here because the information is denser and easily indexed.
In conclusion, this book is a great addition to any library, but not to be relied on for learning. While “The Manga Guide to Electricity” introduces you to the basics very well, unless you want to suffer through the mini chapters, you will be no closer to building a circuit at the end than when you started reading. [Mims]’ book, on the other hand, leaves you with all the skills to begin experimenting with, building, and designing your own circuits. Luckily, at the price range of this book, there is really no reason not to pick it up and give it a read.

You can follow along on the project page to see the major design changes as they happen, such as the wheel suspension system cut from a single piece of plastic. All of the pieces, schematics, and software are available for download. Be sure to scroll down and see ERP’s reaction to some of crabfu’s inventions. | 12 | 12 | [

] | Following up on their post about the
new Defcon 17 badges
, Wired recently posted some of the
best badge hacks of the con
. Among the hacks featured were an LED frequency meter hack, a sound seeking dirigible powered by three badges, and a wireless geiger counter random number generator that sent random numbers back to a laptop equipped with a zigbee card. Probably one of the most impressive hacks mentioned, the hack that won the badge hacking contest, was the LED equipped baseball cap modeled above by [Joe Grand], Defcon’s defacto badge designer.
The hacked badge is connected to the cap by an ethernet cable, where the LEDs pulse on and off in order to defeat facial recognition systems. The cap’s designer told Wired that he initially designed the cap in order to sneak into [Grand]’s room to steal the über badges under his protection. Needless to say, the winner doesn’t have to worry about stealing the badges anymore as he was awarded his own über badge at the award ceremony. While we’re not completely sure who pulled off this awesome hack, we congratulate you and all of the participants of the badge hacking contest on your fantastic hacks.
Update: We’ve confirmed that the badge contest winner was in fact [Zoz Brooks], [Grand]’s co-star on the popular Discovery channel show Prototype This. From all indications, his hack seems to be legitimate and not a clever idea, however we are still looking to confirm this. Also, even though Wired’s article stated that the dirigible was sound seeking, we have confirmed that it is sound avoiding. Thank’s to everyone in the comments for pointing these things out. | 17 | 17 | [

multitouch and interactive demos
have become
increasingly popular
because they’re so easy. Students at the University of Tokyo took a new approach that
uses lasers
instead. They created
Sticky Light
, which uses mirrors, a laser, and a single photodetector. Unlike camera-tracking setups, this system requires no visual processing. The laser moves around and bumps into dark objects, sticking to them. It can follow drawings on the table or objects in space, such as shirt designs. They also created a few basic games and a demo that makes sounds based on the movement of the spots. Video of the project after the break.

was found at Defcon 17 in vegas this year
. Its design has a tinted plastic window at the top which attendees noticed had a computer in it. It was quickly removed by the police. Is this an amazing coincidence? We doubt it. Someone probably knew exactly who was going to be there and either wanted to scam some hackers or just wanted to have some fun. | 49 | 49 | [

little walking robot
caught our eye. We’ve seen tons of 4 legged bots, but the design on this probably took more effort than the electronics. The design is radially symmetrical, it can walk in any direction, turn in place, and even walk upside down. The electronics weren’t forgotten though. This little bugger manages to pull a half our of use out of each battery charging. It communicates wirelessly with a custom dual Wiimote Nunchuck setup via XBEE modules. You can find much more technical details in the captions of the pictures. We’re not positive what processing power is hidden in the bot itself, but we know there’s an Arduino in one of the nunchucks. This might be the brains of the operation leaving the hardware on the bot simply to control the servos. We really like the arc-reactor-esque power display. | 35 | 35 | [

] | [WaveRider] is using a type of
phase shift keying
called BPSK to
transmit digital sound and video
for remote telemetry. Though a higher signal to noise ratio (SNR) is generally sought after with communications, legal limitations are imposed on total radiated power. To balance the two headed beast, he opted out on frequency shift keying due to binary shift keying’s ability to work with lower SNR. This adds the difficulty of properly reconstructing the digital signal at the receiver. A PLL based carrier regeneration circuit is used to reconstruct the signal. Using the
Rabit2000 processor
as the host controller on both transmitter and receiver, 96KB/Sec serial data is obtained. On the other side of the spectrum is the

Diamond thermal paste
and now he’s got more for us. To celebrate the re design of his website, he has
released the plans for the paintball turret
. As you may recall, we
absolutely loved this design when he originally showed it to us
. Though he has had kits available for a while, he has finally put the plans up for download. You can cut your own parts and build it yourself. He mentions that version 2 is coming shortly, we wait with bated breath. | 20 | 20 | [
