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
.
[Thanks pt]

If you’ve ever tried compile a linux kernel yourself you know the headache of configuring and taking care of dependencies.
KernelCheck
makes this a point and click process for debian based linux distributions such as Ubuntu. You can use it to compile and install any 2.6.* stable kernel as well as the bleeding edge. KernelCheck even offers custom compilation options such as including kernel patches or rolling in proprietary video drivers. A
tutorial (PDF)
is also provided so you can see what you’re getting yourself into.

If you don’t have a piece of hardware, a module doesn’t get loaded for it. The only reason a piece of driver code would be loaded is if it was built into the kernel, but with initramfs images barely any driver code has to be built in.> or when a particular piece of> hardware needs to work before> you can load the drivers?initramfs. The kernel also has the ability to have a ramfs built inside the kernel image, so as long as your bootloader is capable enough to load the kernel into memory there is a way to load driver code from modules. The ram fs stuff is jettisoned once the system has chroot()’ed into the real fs, so no memory is wasted on stuff you maybe don’t need.>I’ve run Linux on all sorts of>hardware and sometimes you’ll>save yourself a lot of trouble>rolling your own.I’ll have a whip ’round and get you a medal. If use NetBSD or any other kernel without(not sure if that’s still the case) runtime module loading building kernels can make sense. With most mainstream linux distros there’s no point and only results in you getting called a moron when you come into support channels to get help to with your unbootable system.",

The kernel is a lot more complicated beast than it was 3 or 4 years ago… klibc etc etc. Anyhow most distro’s use initramfs images for booting, its essential if you want to be able to boot from anything more complex than a bios partion on a harddisk, i.e. you can’t mount filesystems from a lot of RAID setups without userland tools, LVM needs userland tools really.>If you want to just use prebuilt modules and be > happy about it then go aheadThe pre-built modules will be exactly the same as any you can build. You realise you can build modules without building the whole kernel right?>do so but don’t insist you know the>only 3 reasons to roll your own kernel.No, there are only around 3 reasons for building a kernel. Unless creating pain in the arse to maintain systems is a reason.>I have had at least 3 pieces of hardware>for which I had to manualy edit the source>for and then recompile in order to get working.Modules can be built externally, you don’t need to rebuild the kernel. Building non-essential drivers, non-essential functionality (Most of the networking, disk subsystems etc can be built as modules and are built that way for the majority of distributions) into the main kernel image is moronic. Especially if you consider the fact that most BIOS/Firmware have major issues and loading big kernels into memory.>I’ve run Linux on x86, amd64,> ppc, ppc64, arm and mips platforms,Ok, let’s have it out then… x86, amd64, Sparc 32bit, Sparc 64bit, m68k, PPC (look up APUS), mips, arm,.. bunch of other shit I don’t care to remember.> and certain issues arise that> necesitate a deviation from the> norm mainstream set up.Everyone that has said that in my experience hasn’t realised that you can A: build loadable modules outside of the kernel, B: most parts of the kernel are tunable at runtime via proc and sysfs interfaces, C: anything that isn’t tunable at runtime can usually be tuned via kernel command line parameters.>is recompiling the kernel needed>for the average user on typical comodity >hardware; NO!99 out of 100 users, admins etc have no reason to compile a kernel, or for matter matter most of the binaries they are running.>but that doesn’t mean there is only>the three reasons you know about to>ever do it. if you don’tyou’re yet to give one good reason,.. having to patch drivers isn’t a reason because you can do that outside of the kernel build.

If you actually need to build a kernel you should be able to use those tools. And no, I’m not limiting the options of others, people that don’t understand stuff do silly things like build all their software and kernel according to “super fast linux howto!!!” then post stupid bug reports etc that waste developers/maintainers time. Just look at all the stupid reports on launchpad. “You must fix! I install packages off of random website!

No rescue shell for you, no ability to move the system to a different machine and boot into it.. sounds good.Oh, it boots about 2 seconds faster because it’s loading a small payload from disk, extracting it to ram and loading a few modules from there.. instead it’s loading the same code from disk into memory as part of your kernel image, oh wait, that’s practically the same thing just done painfully.>I know that kernel modules can>be compiled separately from the kernel>but you have to have the same kernel>source and the same version of gcc to>do so;This tool is for Debian + forks right.. so in Debian you have lots of lovely tools to allow you to get on with productive work,.. tools like make-kpkg, module-assistant, the build-essential meta package,kernel headers packages, kbuild packages, kernel source packages, all the versions of GCC you could need..>by not using an initrd and compiling>only the drivers I want right into the kernelSo you basically put your boot process in a wheel chair and then make it impossible to load “modules” with different parameters at runtime.. god forbid you actually maintain systems for a living.>I’m able to get faster boot times> and waste less disk space as I>don’t have drivers I don’t needYes, because saving >50MB of disk space is necessary on systems with n*100GB of disk space.>I’m not claiming to be some Linux guruYeah, I wouldn’t go doing that, you may look a bit silly.>but microsofts similar close minded>atitude about what people should doNow you really have lost the plot.

SparkFun has released a
breadboard power suppy
that can provide regulated 3.3v or 5v. Unlike the supply we saw
from adafruit industries
earlier this summer, this one is based on an
lm317
. This small device features on/off switch, voltage selection swith, and appropriately spaced pin headers to plug into both the top and bottom rails of a standard
breadboard
. Rather build it yourself? Take a look at the
schematic provided (PDF)

Some advantages:-Huge range of voltages (1.7V to +/-12V)-Huge power output (10's of amps)-Auto shutoff on short circuit – really useful, because you can put a reverse biased diode across the power lines of your breadboard, and if you connect the power backwards, it will shut off immediately.",

Western Digital recently released a
media player
that attaches to your TV and allows you to play HD media straight from an external USB drive to the television. 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.

Lightweight Webkit Based Browsers

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.

Popular Mechanics has a
detailed how-to
on diy ruggedization of common portable electronics such as laptops, cameras, and cellphones. There is
video
of a laptop surviving an eight foot fall due to the tennis balls, pipe insulation, and weather stripping they’ve added. Its not just shock resistant, they’ve used a
two-part compound
marketed for making custom molded earplugs to make the laptop water resistant.

Palm Pre GPS Tweets

[Mike] sent in this project he’s been working on. He has posted instructions on how to
get your Palm Pre to tweet its GPS coordinates
at regular intervals. It does require that you have Linux installed on your Pre, but that’s not that big of an issue as he has
a tutorial for that too
. Getting the tweet to happen involves setting up a custom PHP file that sends the tweet, then a cron job to get it to run on a schedule. He mentions this could be useful for finding a lost phone as well as keeping track of loved ones. We would like to see him add a script to do similar with a picture. Maybe take a picture and upload it every time a call is placed?

writes up
an interesting product called Wire Glue. This conductive adhesive is a paint-on alternative to soldering. At first it seems like a bizarre product but we can think of a few uses. Who hasn’t had a solder joint on a free-formed circuit break? One thing’s for sure, we’d recommend throwing a resistor into that LED circuit he’s working on.

Nokia is currently one of the leading phone providers and intends to jump higher on the scale with the
Nokia N900
powered by Maemo. But what wasn’t expected was for Nokia to step into the netbook pool. Called the
Booklet 3G
, it sports 10.1 inch high(er) resolution display with HDMI output. For connectivity you can take your pick of 3G, WiFi, and Bluetooth. All wrapped up in Windows 7 with a whopping 12 hour battery! However, the problem with all these features is the price tag might eat a hefty hole into your pocket book. That’s not going to stop us from trying to get our hands on one, of course. Anyone have any
hacks
planned yet?

Google has opened up a new
Android Developer Challenge
for submissions. About $2,000,000 in prize money is available, with $250,000 going to the best overall app. Submissions are due by August 31, leaving about a week to get apps in for judging. Time is short, but the prizes are big. Hopefully we’ll see some exciting things come from the contestants now that the community has grown since the
previous ADC
in 2008.

210 LED Lamp

Current fluorescent lamps are great for lighting large areas using very few Watts; however, LEDs are far more efficient at producing light and have less of an impact upon the environment considering there is no mercury within them. [Andrew] sent in his team’s
LED florescent bulb
. The first revision utilized 87 LEDs, but to increase output the second revision uses 210. The assembly can’t actually be placed in current fluorescent lamp ballasts and must use a 12 volt 1 amp power supply, but perhaps future versions will correct for this. Another problem is the relatively small viewing angle, and while there is a diffuser, we’re wondering if they have any other ideas to spread the light and adjust for the color temperature without reducing output? We wonder how it compares to some of the
commercially available LED florescent lamps
.

We will try to use them to improve what we wrote so far and to try to eliminate any misunderstandings.There is more than one advantage to using LEDs; so please don’t rant about one concept only. I saw that efficiency comparing post (http://bits.blogs.nytimes.com/2009/08/04/leds-as-energy-efficient-as-compact-fluorescents/?scp=1&sq=led%20vs%20floursent&st=cse). I actually agree with it, but we don’t pick LEDs just because one advantage.Besides green, LEDs are also less toxic than fluorescent(toxic stuff is trapped in plastic, not in a gas as it is in fluorescent). Second, you can run these lamps on low voltage, without the use of balast (our “system” idea was part of the project, just not on the site yet). They’re even recyclable(the only things that make an led end its life is the yellowing of the plastic around it, that can be fixed in the future). And they’re much more flexible, you can use PWM as stated and so on (One guy at the fair was even saying that we could use them for wireless information transmition like seen on here:http://www.sciencedaily.com/releases/2008/10/081006130548.htm)If you guys want references, we can get you some.

Nice work y’all.However, the above quibblers are correct– as the technology currently exists, LEDs are not nearly as efficient as fluorescent lamps, especially in the warm white range.As such, their environmental benefits are also dubious. Most electrical power comes from coal in this country, which releases mercury into the air by the ton. More power used is more mercury in the atmosphere, where it is a greater threat than the small amounts used in fluorescent lighting (which is reclaimed when properly disposed of, in any case).LEDs are also plagued by a number of technological problems such as high expense, poor color rendering, inconsistent color temperature, poor lamp life, and rapidly diminishing light output– try running that lamp you’ve made for 5000 hours and I think you’ll see what I mean.A good reference for the existing state of the technology is the DOE’s CALiPER test, which test and compare real products available on the market today.",

The plastic package remains water clear. I have looked at a selection of white LEDs from various sources and the effect of dimming with age is consistent. Better ones seem to be composed of several different color chips and no phosphor.Perhaps you could try the same experiment but interleave red, blue and green or yellow LEDs, adjusting the current in each color to give the best light. I think the spectrum will still be very uneven, as it is with fluroescent and regular white LEDs, but at least you will have some control over the color.",

Routers aren’t just for routing network traffic any more. With the help of alternative operating systems such as
DD-WRT
,
Tomato
, and
OpenWrt
, routers are now extremely customizable and can be utilized to
suit a number of needs
. The main issue with projects built around routers is the need to telnet or SSH into them to get to a console. [Sven Killig] came up with a useful solution that utilizes the USB ports available on an Asus router to
display video on a DisplayLink device
, allowing a user to sit down and use the device as though it were a physical terminal. This would be a good DIY alternative to
commercially available routers
that display network graphs, system information, incoming email, and other data.

Every electronics workbench could benefit from having a bench power supply. Converting a PC power supply works, but often, it involves splicing wires and limits the supply to only bench use, and
building one from scratch
is definitely an undertaking. To counter this, [silic0re] and his father came up with a
detachable adapter
that simply plugs into the existing connectors. The adapter provides posts for four different voltages and can be built in no time. It’s nice to see a solution that will let you use any power supply laying around without having to worry about the dangers of opening it or cutting it up.
[Thanks silic0re]

Autogiro POV Nostalgia

This bit of nostalgia really caught our attention. A german hacker or “inventor” as we were called back then, came up with this interesting concept. He would
project an image on to the moving blades of an Autogiro
, relying on the POV effect to make it appear complete. While this is not the same system of utilizing POV that we currently use, it relies on the same principles. It looks like he’s hanging the projector or “magic lantern” from below the Autogiro, using the length of the rope to hang it as a focusing system. Were this to have actually gone into production, it probably would have really freaked people out. If only he had had access to something along the lines of the
ceiling fan POV system
.
[thanks itay]
[update: Why didn’t we look around for this earlier. It was brought up in the comments, there is in fact a POV system for R/C helis.

Maple Beats Up Arduino, Takes Its Shields

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.

"content": "“Can you say “Parallax Propeller”? A mere $7.99 per chip for 8 CPU cores running in parallel at 80Mhz.”Each propeller instruction takes four clock cycles, so 80/4=20 MIPs. (PICs typically take four clock cycles per instruction too). An ATMega168 runs at 20 MHz with the vast majority of instructions taking 1 clock cycle per instruction, so you get 20 MIPs. Same as the propeller.Each propeller CPU (or cog) is very limited in cog ram and using hub ram is slow and complicated. If you do use hub ram often the complex task of managing resource locks rears its head. Then there’s the complexity of managing the cogs themselves not to mention the difficulties of communicating between the cogs. The output pins are shared between cogs, that has to be watched carefully.I’m not saying the propeller is defective in design, any multi-core processor would present these same issues. I just want to balance the original poster by reminding the potential propeller user that there are some steep hills to climb with this part.The 40-pin DIP propeller is out of stock again. As far as I know there’s no free C compiler that’s easy to use and supports double precision floating point. (At least I find Catalina difficult to use). The Imagecraft C compiler ($) only does single precision floating point. There’s no intellectual property protection and you have to use an external I2C EEPROM with the propeller.Propeller’s native SPIN interpreted language is REALLY slow. I just implemented some simple routines in propeller assembler and spin and found spin to be around 100 times slower than assembler.Each propeller cog has two powerful timer/counters so there are 2×8=16 timer/counters total. If your application needs a lot of beefy fast timer/counters, you con’t beat the propeller.",

The best thing to come out of the arduino thing is that there is lots of cheap atmega168 boards with usb out there that you can exploit with avr-gcc and avrdude. You can also find cheap Atmel STK originals and clones though.I would just go for a Seeeduino however; Their boards have spaces for correctly sized headers, have an FT232 onboard etc etc..",

When i was playing with a pov display i didnt want to invest insane time into something i knew deep down id figure out then rip back apart. The arduino and avrs are perfect for that sort of thing. Simple to use and reprogram. No pic chiptochip weirdness. Plenty of power. The arduino is the perfect speed/cost for most simple applications (far better than most pics).If you have a problem with arduinno pin spacing the solutions pretty simple. Breadboard one or etch a one sided pcb. If you want that and a bit more space get/make a sanguino.Im hopefully moving to high speed arm (if i can afford it) as i see theyve put out some HIGH speed chips finally that are ubercheap. I’ll still use my arduino and collection of random avrs for all the small stuff (meters.. lighting thingamabobs.. whatever). When i want to make a diy palmtop ill use the arm. But im not going to waste the cost of an arm chip + components on something i hate to even spend 10 bucks on.Everything has its place. Ease of use is a big factor or a lot of us would be debating the (faster) SX chips or 8051’s or whatever. Heck i have a 33mhz dallas 8051 with networking et al sitting in my commponent box right now ill probably never touch (its sampled). I dont use it because i dont have a need atm.

The Serpent Mother
is certainly an appropriate name for this 168foot long snake fire art installation filled with enough goodies to impress anyone who is into flame effects. [
The Flaming Lotus Girls
] were allocated $60,000 in May of 2006 to bring this art project to
Burning Man
. A team of nearly 100 people worked together at a furious pace to pull it off. The collaboration of skill-sets is unfathomable between the metal art, firmware, software, LEDs, and propane design. 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.

Bottled Nixie Clock

Who could not love the tender glow of a Nixie display? It isn’t a new concept for them to be used in
clocks
, and usually it’s how they are housed or encased for display that sets them apart. [crazy_phisic] did the near impossible by building
his Nixie clock
almost entirely inside of a glass bottle. The circuit boards and logic components were soldered outside, but the final combination of parts (sometimes requiring specialty homemade tools) were assembled inside. We wonder how long it took him from start to finish after learning boats in bottles can take from minutes to months. The original post is in polish, but if you want to find out more there is a
Google translation

Homebrew Wii Via The Bannerbomb Exploit

The Twilight Princess hack doesn’t work on newer versions of the Nintendo Wii, but thanks to
a new exploit
for the Wii, homebrew is still possible. Using an SD card and a few files, you can have the homebrew channel up and running in no time. The folks at Lifehacker show us
how it’s done
. It’s good to see that the Wii modding community is still in full force. Hopefully, this won’t turn into a back and forth battle between modders and Nintendo, like it has with
Sony
and
the
PSP
.

I decided it was best to wipe it clean of homebrew and update to 4.0 so that Nintendo wouldn’t void the extended warranty. I got it back with 4.0 and I had to use Bannerbomb to get homebrew back, though it worked great. Only problem is, since this is a direct attack on the system menu, it is going to be a quick fix for Nintendo. If this fails, I read about another exploit based on the Twilight Hack that uses a malformed Brawl stage to crash the Wii. Since nothing is stored on the Wii directly, it is pretty much impossible for Nintendo to patch around other than by making new Brawl discs and stopping new discs from being exploited.",

I’ve tried it on both system software version 3.2 and 4.0 and I haven’t had a single problem with it. Even better is it gives you the choice of launching the program or ignoring the exploit and letting the Wii system function normally, which means you can leave the program on the SD card at all times without ever having to remove it. This is a good step forward from having to buy a specific Wii game to exploit a saved file (which I had to do before this exploit came out, thankfully it was a decent game). A+ to the creators.",

OpenPogo, An Alternative To Pogoplug Software

Many of us heard the news of Marvell’s
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.

Passive Infrared (PIR) Sensor Tutorial
|
Phil Burgess
|
[
"Arduino Hacks"
] |
[
"infrared",
"ir",
"pir",
"sensor",
"sketch"
] |
[ladyada] has a freshly-published and amazingly thorough
tutorial on passive infrared (PIR) motion sensors
. 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.

Tunneling IP Traffic Over ICMP

We all hate it when we find an unencrypted WiFi network at our favorite coffee shop, restaurant, airport, or other venue, only to discover that there are traffic restrictions. Most limited networks allow HTTP and HTTPS traffic only, or so is the common misconception. In the majority of cases, ICMP traffic is also allowed, permitting the users to ping websites and IP addresses. You may be asking, “Ok, so why does that matter?” Well, all of your IP traffic can be piped through an ICMP tunnel, disguising all your surfing as simple ping packets. [Thomer] has a
detailed guide
on how to create and utilize such a tunnel using ICMPTX. So the next time you are at the local cafe and want to fire up VLC to watch TV shows from your home PC, give this guide a quick read.

I don’t think it effects any other “passing through” packets.Having said that, ICMP can’t properly be put through Network Address (and port) Translation because it doesn’t use port numbers, so most places will use an ICMP Proxy application on the router to keep track of all of the packet flows. (your average Linksys router has this built in) That program has to keep a state of all outgoing and incoming packets, and unlike IPtables connection tracking within the Linux kernel, I doubt it’s super efficient, so you might well find that only a few hundred packets per second could make the poor old router run out of RAM and freeze or get CPU bound and drop packets.",

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.
[thanks Eric]

(the sensor is isolated from ambient light, and then the beam of the led is narrowed down with a small tube so it enlightens only a small spot on the paper)the robot scans a 12×12-pixel image and processes it with some sharpening algorithm and then performs a very primitive ocr-algorithm on it. (comparing to reference-images)the solution is then calculated and the result is written with the attached pen.the whole thing is implemented with several threads so that the ocr can run in the background while the next image is scanned.the plotter approach has been chosen because all the other approaches were too loose.thats why i admire this guys work, since he managed to get it working with a setup which has a lot of inaccuracies.",

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!
Hack a Day has
previously covered other Waldos
, but this latest deserves style points for its lightweight simplicity.

[Patrick] has a pair of Klipsch speakers that continually needed the volume knob cleaned. After a bit of research, he found it was a common problem with the potentiometer chosen for the task. He decided to resolve the problem, not by replacing that potentiometer, but by
modifying the speakers to be passive and running them from an external amp
. While this does sound simple at first, he wanted to retain the rest of the electronics in the unit, so a bit of hacking was required. You can follow along through the whole process on his site.

[Reid] wrote in to show us how to
add a second hard drive to his Macbook Pro
. He found that he hardly ever used his DVD drive, so sacrificed it in favor of added storage. What he found was that it had a proprietary adapter that he was unable to find for sale anywhere. Making an adapter may seem like a pretty simple hack, but this could save some people considerable time. Its also worth noting that upgrading the firmware got him an 18% speed increase, so don’t ignore those updates. We don’t see too many mac hacks around here, you may recall the
mac tablet hacks
and the
logo monitor
.

Aspire One External Antenna

"wifi"
] |
External antennas on netbooks are notorious, from
EEE PCs
to the
Panasonic CF-R1
, but this is the first on an Acer Aspire One we’ve seen. [xRazorwirex] sent in his
external antenna hack
for the 802.11n capable D150, with the intention of increasing performance, but he says he can’t attest to any change. Unfortunately the lock slot had to be removed, but a small price to pay for a big increase in connectivity. The process seems simple enough, and could probably be done within a half an hour. Now that there is an external link why not build a
Cantenna
, hop in the car, and
HeatMap
the neighborhood!

I may roll back to my G card and do some performance benchmarks in Omni-Peek for the sake of information collection. I also don’t know if only upgrading one antenna makes much of a difference, as it still uses 2 (if G then 1) of the original antenna. If anyone knows more about this I am all ears. I would like to find out if maybe one antenna is dedicated to discovery or something like that and use that as my external antenna.I took it out with a D-Link ANT24-0700 which has a magnetic remote base, and driving around town I snuff out some serious packet-age running Omni-Peek and had I see far more networks than I ever did before.Maybe tonight I’ll use Ekahau and heatmap my town.. sounds fun.",

Although we’ve covered
DIY ECGs
before
, [Scott Harden] sent in his version
that gives an in-depth explanation
of what to do with the collected data. He built a basic battery-powered op-amp-based ECG for under $1. The circuit just amplifies the signal from the chest leads and feeds it into a computer via the microphone port. He then used
GoldWave
to record, filter, and save the signal. From there, he used python to analyze the heartbeat and calculate his heart rate and further manipulate the data. His
previous blog posts
go into more detail on how the python code works and why he chose software over hardware filters.

Twitter has been used for lots of experiments, both
useful
and
just for fun
. [FIRESTORM_v1] sent in his project that falls under the useful category. When he wanted a way to monitor his server’s power statistics, Twitter was a logical choice. Similar to the
Tweet-a-Watt
, he wrote a script that posts messages from APCUPSd to a Twitter account that he follows, and gets the updates on his phone. [FIRESTORM_v1]
documents
all of the scripts he used and the steps to get your server up and tweeting.

Arduino USB Host Shield

Circuits@Home
has been journaling their development of a USB
host mode
shield for Arduino, which could bring the platform a veritable explosion of mass storage, keyboard input and countless other peripheral options (and a corresponding raft of new hacks). Currently at the prototype stage, a ready-made shield and library are forthcoming, so keep checking back. Meanwhile, for embedded developers wanting to learn the ropes of USB, the
in-progress articles
will likely provide some valuable insights.

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.
Juicebox
, anyone?

Handbot, The Shelf Climbing Bot

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.

Layar
brings augmented reality to your cellphone with the release of
Layar Reality Browser 2.0
. Partnering with Layar,
Brightkite
improves the experience by accessing their content, along with Wikipedia, Twitter, and other services; then by using the camera on your cellphone, maps friends and other users data on the screen, over top of the live feed. Simply aim your camera at a bar and find that two friends are inside, and read a reminder to yourself that you didn’t like the live music. It’s interesting to see how much is already implemented, and with an additional 500 API keys released, what new things will come from Layar?

PS3 Slim Axes Linux Support

We may have all been eagerly awaiting the arrival of the PS3 slim, but don’t get too excited yet. According to an
official press release
from Sony, the PS3’s slimmer counterpart is dropping the ability to install Linux or another operating system. It’s always a shame when new products come packed with less features, but this time, it’s preventing us from doing things like
cracking SSL
using 200 of the consoles, or
running emulators
from an Ubuntu install on the console. For those of us that still plan on keeping our “old” PS3s, Yellow Dog Linux has been
released on a USB stick
and allows you to run without having to do a full installation.

That sucks.Hey at least you get a more compact design and a 40nm CBE in the cech2000/slim.The drivers and MMU filter/hypervisor all run on the 7th core and each SPE controls access to it’s local store internally. What this means is a out of bounds security model. A heap or stack overflow or any other memory corruption would have -0- effect on the native management code.It’d take something like a DMA attack to get into secure mode considering they didn’t run the h.a.l in otheros mode/lesser privladged ppc mode while in gameos mode. They do run the browser and most XMB applets in the unprivileged mode from gameos mode and they are all sig checked then decrypted when loaded.The x360 hacks are all thanks to the upper 30bit control vector vulnerability and a DMA attack. The ps3 doesn’t use a global address space and the hypervisor is just using hardware features that are in no way dictated by any code. It’ll be interesting to see what happens.",

"content": "@rude dude: Still nobody is playing those pirated games. They are getting released every day but no method of playing (except with a development kit) is known to play them.The problem with this generation of consoles is the lock-down. Xbox 360 is the worst offender as it has taken years just to be able to run unsigned code. The shader hack was good, but then that was patched shortly. The timing attack requires some more-than-average skill. There are no modchips that are worth anything yet.The PS3 has Linux support, but it is crippled. No access to the GPU for 3D? Simply ridiculous! WHO is going to make a game for PS3 Linux? It would be not worth the time or money or maintenance costs. I think that is what Sony was afraid of if they let Linux utilise all the hardware of the PS3. Games still get dumped via dd on unpatched PS3’s (nice going Sony). This was the same with PS2 for Linux. It too had limited access to the hardware and could never utilise the PS2 completely. Homebrew overcame this problem and quite quickly too.The Wii is the best in this regard, even though the latest firmware patch is ‘fixing’ the ‘homebrew problem’.I wish companies would just let us at their machines. To me it’s like not even owning it. It’s like owning a license to HARDWARE! That is how the development kits are distributed to developers. But this is consumer stuff. I really believe in the right to tinker, and apparently these companies do not. I would suggest just not supporting them at all if you can.",

Worse graphics than what? How much do you need to spend on a PC to get on par with a 360/PS3?2. Bad control? No idea what this means.

Perhaps we can also regard this as a hack challenge; get Linux running on the PS3slim.Whereas I can see Sony’s logic in discontinuing visible support for features that few customers actually use, it would be nice if they offered an “other-OS” enabled and/or an emotion-engine model. The difference initially would be only that Sony would be getting our money for the premium, vs. resellers of the classic 60GB (used) model, of which I own one. Ultimately, the premium on the fully-functional classic will rise from resellers, until PS4 is released. I wonder if they will support PS/PS2 but not PS3 on that model?Also, I play PS, PS2, and PS3 games on my PS3, and have Ubuntu Linux installed as well. Why? Why not?",

The 20th
Hacking At Random
has recently come to a finish. For the unititiated, Hacking At Random or HAR is a massive hacker festival that happens every four years in the Netherlands. Four days of technology obsessed hacking with roughly 2500 people definitely piques our interest. The event is riddled with classes and people speaking on subjects such as censorship and robotics. Quickly built networks sprawl across the entire area, with shacks set up for location of servers. We think there should be an official Hack A Day tent there next time. We mentioned HAR when we were talking about impromptu
DECT networks and DECT phone modification
. Be sure to browse through the multitudes of pictures located on the
HAR website

[Dave Vondle] from
IDEO Labs
sent in the
large LED pixel wall
he built using
BlinkM
modules, an Arduino, and Flash to control it. The overall result is a blindingly bright, large, public display for people to interact with. The best part about the project is that [Dave Vondle] documents everything; from hardware to schematics to source code. Unfortunately, he was forced to remove the wall due to construction, but since every part of the project is open source, it lends itself to be easily recreated. I’m sure we’d all like to see a wireless controller hookup to play pong on the streets of Chicago.

I am currently in the process of enhancing the MaxM port to support 16 bit hardware PWM with logarithmic power output during dimming (to give brightness output that appears linear), and hopefully I’ll be able to add some other neat tricks too that are not present in the shipped firmware, such as light script enhancements.",

A lot of others have extended it since as well. Compared to the last BlinkM firmware, the CYZ_RGB offers full 16bit PWM and a LUT for custom color calibration. It is tuned by default to be a pretty good match to the SRGB color space for most high brightness RGB LEDs, but the LUT can be adjusted . Also the BlinkM firmware has some kind of i2c bug which causes bus lockup in extremely large topologies. The bug was in the Atmel reference i2c implementation at the time; I had it too, so I am thinking this is the same bug.The thing that prevented ThingM from releasing their source code is that they proactively licensed a philips patent related to controlling RGB LEDs over i2c. The patent specifies that the i2c bus runs over “flexible” wire (like xmas lights and similar) so I can see their point. It is my understanding that the patent license prohibited the source release. In my own hardware I put many uCs on the same board and my bus ran only over PCB traces, and I drive long LED chains using high power mosfets.Whether it may have eventually found its way out or not is irrelevant, CYZ_RGB is better in nearly every respect. The only downside is that it does not offer as many preprogrammed sequences.In any case the shift-register based approaches that are de rigueur these days are considerably more cost effective than using attinys as led controllers. Though perhaps it would be fun to make a minimal port to attiny0",

"content": "Hi. I’m one of the guys who makes BlinkMs. I agree that shiftbrites are great for making large LED arrays, but what Dave is doing that IS much easier with BlinkMs is that he’s letting each individual unit do its own fading. That way, he has to send much less data to get each individual unit to fade from color to color. His hardware only has to send a color and a fade time and let the BlinkM do the hard work of interpolating between two colors and smoothly fading between them. That requires much less bandwidth and lets him address individual pixels in the array without keeping track of what’s in the rest of the array. Also, because he was buying such a large quantity, we gave him a discount, which we’ll offer to anyone else who’s buying that many. Send a note toblinkm@thingm.comif you’re interested.Also, fwiw, John’s doing great stuff with the cyz_rgb project. We will continue to ship BlinkMs with our own firmware, but if you’re comfortable with an AVR programmer and embedded systems programming, we encourage you to take a look at that project.",

Quick And Dirty Magnetic Card Reader

[nevdull] found himself in possession of a magnetic card reader. What else was he to do but show us all how to
read from it using an AVR
? He goes through the basics of how the card reader works, as well as how to detect the different card states such as entering, reading, leaving. There is source code to download to try for yourself, but unless you have the same reader, you’ll have to do some modifications. While this doesn’t get you all the way to reading the complete content off of the card, its a great start. Maybe you guys can help him finish up the last bits.

In this project,
a moon phase light is modified
to show the actual moon phase based off of your computer’s internal clock. From the factory, these moon lights are updated via an infra red remote control. 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.

The folks at Revision3 really know what gets our pulse going. In this episode, they show us how they built a
radio controlled keg
. Not only is the system built sturdy enough to cart around the keg, it is also built with the capability for the driver to control the beer flow. This isn’t too shabby for a pretty quick project, but it
still can’t compare with Bar2D2
.

Cheap SD Card Cradle

When utilizing an SD card in your projects, you would generally buy an SD card slot to wire in. Sometimes, you just don’t plan that far ahead, or maybe you just want to play with an SD a little bit to see what you think. [Kroden] shows us how to make a fairly
simple and cheap SD card dock
. The result is actually pretty impressive looking. He has simply bent some header pins and soldered them together to make a simple SD slot. It can even be adapted to a horizontal layout for more permanent use.

iFixit has done a tear down on the symbolic do-it-yourself Espresso machine,
the Starbucks Barista
. Believe it or not, there is not a single circuit board in the works. There doesn’t seem to be much to the Barista; A few switches, some solenoids, a heater, and one way spring valve among other things. The assembly of the device is very simple. 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. We have pondered the possibilities of this machine numerous times, while enjoying a cup of cappuccino. Though most conversations end at the bottom of the cup, many survive such as this
Silvia PID looped expresso machine
. The very name “
Mecha turbo crazy coffee roaster
” seems to encapsulate the effects of caffeine quite adequately.

The Starbucks Corporation has determined that some people value a Starbucks crapaccino maker more than they value two hundred and fifty pieces of green and yellow paper with pictures of dead US presidents on them, and they are happy with the number of people who see this valuation. There are probably people who would be willing to pay $500, or even $1000 for such a device; the point is, everyone’s valuations of goods and services versus their valuation of dollars is different.The relationship is a two way street. Starbucks Corp values $250 more than they value yet another machine. This disparity in how Starbucks Corp and Starbucks customers value simplistic coffee machines is the very mechanism that makes trade possible, and why free trade always increases the value held by the parties involved.A company should absolutely charge as much as “the market will bare”, because to do otherwise is inefficient. A company has a responsibilty to pay its employees and share holders, and they can only do that well when they are making a profit. Efficiency is a very hot topic in today’s political and social discourse.

Meet
the Wakeup Machine
. It is here to ensure that you are up and ready to go when the time comes. This machine will vibrate your bed, remove the sheets, make coffee, play music, even adjust the temperature in the room for optimal wake up experiences. We like the large heavy industrial look of it too, but after looking inside you’ll see it is only a prototype which could be made much smaller with its own pcb. This thing brings back fond memories of
Rube Goldberg
style alarm clocks from movies such as Pee-wee’s big adventure, Back To The Future, and even Chitty Chitty Bang Bang. You can see some videos of the device on the page as well as download complete plans in pdf format. The did forget
one feature
though.

[Tim] noticed a 2.4Ghz WiFi spectrum analyzer on thinkgeek a while ago and got curious. He knew that the spectrum analyzers with which he was familiar were giant expensive units, so he got curious what this little dongle was. It turns out, it really wasn’t much at all. Just a simple wireless receiver. He decided that rather than spending the $399 for one,
he would toss one together
using an
Xbee
. His total cost ended up at roughly $50 for basically the same unit. While he doesn’t give a schematic, you can download his source code on the site.

"content": "Well, drat. I’ve been working on the exact same project (using a TI EZ-RF kit as a spectrum analyzer) and was going to release my code and writeup in a few weeks. I’ve been beaten to the punch.Anyways, yes, the idea is you just use the native off-the-shelf kit to poll the CC2500 for the RSSI. This has been done before in the mentioned article many years back (based on AVR to drive it), and is available as a ready-made Arduino shield that is in the $60-80 range, IIRC. I ran across another recent device that was in the ~$40 range. The older Wi-Spy hardware also (still at $99 right now), surprise surprise, uses a CC2500 too….so it’s the exact same thing basically, except they use a different MCU to drive/poll it and offer an external antenna connection for better reception. The newer hardware is much more purpose-built and dual-band, so the new stuff wouldn’t compare per se.Keep in mind, the $50 TI kit gets you *two* boards and full dev tools. Or you can buy one board for $20. To me, while this has “been done before” in general, I strongly believe it hasn’t been done before at these price points. Further, this is just insanely hackable….couple the board with some batteries, some flash, and some smart firmware for efficient storage and now you can have a stand-alone logging spectrum analyzer *without the need for a PC*. That’s a very fresh angle. Need to do a wireless rollout and want to profile the noise at multiple locations around your building? Do you really want to leave $1000+ laptops with wifi cards laying around in order to log general spectrum congestion over large windows of time? How about you just leave behind a $25 gadget and not worry if it gets stolen, etc.? Lack of RTC complicates things somewhat, but the direction is there.Also, output is output…I think it’s very possible to get this hardware to spew data in a format that would be compatible with the Wi-spy software and/or the linux open source variant (especially given that this hardware is on par identical to an actual existing albeit older Wi-spy device). I poked at the idea, but by then I already had some basic software I cooked from scratched and I wanted to focus on more hardware angles.So yeah. Concept is not new, but the cost and hackability offer up new options for exploration. I don’t think it should be readily dismissed as old news.",

Have a look atthis circuitcellar project(before it expires from google cache; looks like circuitcellar pulled it), I found this halfway through the project and it ended up providing some insight into the CC2500 registers. I thought publishing an implementation on an inexpensive off-the-shelf devkit would lower the barrier to entry vs. “first spin a board, then go on digikey and…” :-) The schematics for the devkit are available from TI’s site or the included cd-rom.The other idea is that the underlying principle is very simple to adapt to other radios you might already have on a development board or Arduino shield, e.g. XBee. Of course, if you can register-bang an actual Wifi card (or let a program like NetStumbler do so), many of these cards will provide this data as well.@cail: Good point about detaching the 2nd microcontroller board from the kit and using it as a long-term unattended spectrum logger. Even without a hardware RTC, setting the msp430 down to its lowest internal oscillator speed / lowest active mode, it will draw ~2uA in a software delay loop at 32KHz. At light duty that could run for a year on the included AAA battery holder, logging data to the msp’s onboard flash for later retrieval.",

When [Jespersaur] purchased a
Luxeed LED keyboard
, he was disappointed to find that the drivers were not open source and didn’t support all the features he wanted. His solution?
Hack the drivers that come with it
, and implement his own. In his article, he gives a basic rundown of beginning reverse engineering by multiple methods and a brief introduction to
libusb
. For the Linux drivers, check out [Kurt Stephens]’s
site
, where he supplies a link to the source code, instructions on building it, and a tutorial on sending commands to the keyboard.

You can watch above as a change in the operating software is propagated across the grid. You can see the LEDs in the video going nuts, there are actually LEDs on the sides too. [Justin] described it to us as a personal fireworks show on your desk. This system is fully open with the schematics and source code available on their site.

Anyhow, this isn’t really all that hard to do if you can get your micro to do serial comms and can think up a basic protocol. Hardest bit will be writing the code to receive the new code and flash it without nuking itself. Atmel has an appnote on rewriting an avr’s flash during operation I think. Some chips have a section of flash reserved for bootloaders like this.. Google knows all.",

Condom Testing Robot

Broken condoms are a serious concern, not only for those who break them, but the companies who manufacture them. When studying the common reasons for breakage, a
coital robot
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
big picture
? The comments might want to stray towards future tech and possibilities, but we’re curious what there is out there currently and how robots are helping the industry.

[Justin Lemire-Elmore] spent one month riding his electric
bike across Canada
last summer. He made the journey from Vancouver to Halifax in 30 days using a mere $10 worth of electricity to recharge his bike. He put together a rather bizarre looking semi-recumbent bicycle to hold all of his gear. The motor controller, charge controller, battery packs, and lighting system were all his own design. He has a captivating
2 hour presentation
embedded below in which he describes all the problems he had with his equipment during the trip as well as all the great experiences the journey offered.

This clever Instructable
demonstrates how to etch beautiful aluminum control panels for electronics projects. We like how similar this process is to
DIY circuit board etching
. Both abide by the same technique and use blue transfer paper. The primary difference is in the use of muriatic acid and hydrogen peroxide for etching aluminum.

Xbox Crammed Into Inch-thick Package

Reminiscent of [
Ben Heck
]’s portable and laptop console mods, [Bandit5317] over at
Xbox-Scene
managed to fit the guts of an original Xbox into a custom-built slim case that measures just 2.5 centimeters thick. In his post, he describes some of the difficulties of cutting down a behemoth Xbox to a third of its original size, such as rewiring a custom IDE cable to avoid the extra 1/16-inch it would take to fold a standard one. 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
XBMC Media Center
and you’ve got the slimmest home theater PC on the block.

Everybody hates it when they have to rename a fileset to fit a new naming scheme. Instead of doing it the hard way and writing a one-time script to go through and rename everything, check out
Bulk Rename Utility
from [
Jim Willsher]. It provides you with a multitude of methods to take care of business and allows you do pick your favorite method, be it regular expressions, simple finding and replacing, prefix/suffix modification, or a combination of many more.
However, if the sheer amount of options available overwhelms you or if you just want an easier way to do things, check out
A.F.5
from [
Alex Fauland]. A.F.5 offers features like adding a counter to your filenames, change file attributes, and save your rename settings out to a file for repeat use.

Well, i had, and i can tell you that this is not like thoose days anymore.And if you like, you can take a look at this post (it is one of the firsts posts of hackaday):“welcome citizen engineers. hack a day (beta) is a web magazine devoted to cataloging all the best hacks, mods and diy (do it yourself) projects from around web. each day i’ll post one hack i like, seen or tried and once a week a special how-to. this is in beta, so enjoy the occasional oddity and sawdust while it gets cookin.why a site? i thought it was time to have one spot on the web with all the things you can do with ipods, digital cameras, consoles, portables, locks, macs, pcs, anything that can be modd’ed or hacked. a lot of the desire to do this is so i don’t have to hunt around as much for ideas. the goal is for anyone who–has an old pda, a tivo, an atari, an ipod, xbox, or any device just sitting around, then hits hackaday.com, bang, sees all the things folks can do with it to void the already expired warranty or get more out of it.i’ll post some resources like make, pop sci, books and other things to check out too since i get get asked about that a lot.”link:http://hackaday.com/2004/10/07/introducing-hack-a-day-beta/So yeah, i complain about this kind of post, because this is not what hackaday innitially was intended to be.i am not angry, i am sad. i (and the little bunch of people that remains here as readers, from back 2004/5) miss the old posts style, the black & white photos, and the good commenters.Ps: i do not complain about how many arduinos they use in a cat dispenser. i do not like this kind of posts, about stupid software or obviosly pay-per-post ad.they still do post really nice things, but they fill the remaining “minimun posts per day” with, sadly, crap.Back in 2004/5 they did not post very often, but the posts was very good stuff in general.ps2: sorry for my baaaad english.ps3: i know i will probably get banned from the comments (because i had before), but i really do not want too much to comment in this days..",

There are myriad file transfer services on the web.
Streamfile
tries to set itself apart by providing a unique secure service. Their file upload system is all JavaScript and doesn’t rely on Flash. It uses SSL to secure the file transport. As soon as you start uploading the file, you can hand the link off to your recipient and they can start downloading without waiting for the upload to complete. The free limit is 150MB, but their PRO service allows 2GB files.

Recently, our friends over at Adafruit released a new version of their popular
TV-B-Gone kit
. Built in cooperation with [Mitch Altman], the inventor of the TV-B-Gone, the new kit sports four high power IR LEDs, two wide beam and two narrow beam. The four LEDs give the new TV-B-Gone increased range, with a maximum distance of over 150ft. 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. The new TV-B-Gone kit is
now available in the Adafruit store
for $19.95 plus shipping.

All this does is piss off customers, make for work for the staff (I’m guessing Lady Ada never worked retail or in the restaurant business), and further perpetuate the “nerds are annoying and antisocial” stereotype.Also, why hasn’t the FCC shut down “Lady Ada”‘s illegal cellphone jammer sales? Funny how all the HAM operators seem to get why this stuff is illegal, but a bunch of special children seem to think it’s their right to fuck around with a communications medium others depend on.Then again, what do you expect from a child who was almost kicked out of MIT for planting a device in a parking garage without permission that was suspected to be a bomb.

But just because you don’t like something, doesn’t mean it shouldn’t exist. If you don’t want someone turning off your TV, put a piece of black electrical tape over the IR port (or you could desolder the IR receiver from the PCB for a more permanent solution).IR ports are just another security flaw in public devices and the reason why some people sell TVs that don’t have them. What’s the difference between using a tv-b-gone and a universal remote at a sports bar?@ladyada I love these things. I had a few hours of fun in an electronics isle at a local retail shop a while back. Just had to look out for the security cameras.

The reason it works is because it floods the room with a competing signal, no remote on those frequencies will work.To try it for yourself, take two remotes, one that will transmit as long as the button is pressed down. Now try to use another remote in the same room. If the frequencies are the same, the other remote will not work as long as the first remote is transmitting.Fun to watch people try to figure out , is it the batteries ? the remote broken ? The tv ?

The TV is regulated to make sure little kids aren’t scarred to heck when they see mass murder right after they finish watching the cartoons in the morning. So obviously that is a necessary action.The example I used was meant to show that it would be unfair to not be able to use something legal you rightfully own (i.e. your TV) when you want.Instead of the Gov, per say, how would you like your next door neighbor controlling your TV from their window?

Please do not ask me to assist you in such matters.” saying incorrect and untrue things about the project or ladyada doesn’t help an anti-tv-b-gone argument.4. the tv-b-gone kit is very popular with workshops, ham radio groups, hackerspaces, schools, events and more. if it wasn’t, there would not be demand for it – so far no individual we know has caused problems with the device. i think everyone realizes it could be used to annoy, but the same can be said about any electronics device (tvs, cell phones, etc).that said – gizmodo did a “stunt”. it was (and still is) the most popular video/page on their site. they make $$ by pageviews and at the time their authors made $$ by page views, this was not a kit maker or individual and the gawker videographer was also punished / banned from the event.5. one of the best uses i’ve seen for the tv-b-gone is turning off tvs in empty offices and stores at night. all over the world tvs are just left on with nothing on the screens, turning these off saves power. many people ask if there is a way to turn off all the lights in office buildings for the same reason. we don’t have a kit for that but we do have the tweet-a-watt that can at least monitor power and help encourage conservation.6. many tvs have a “disable remote” feature. this is something that tvs have to disable any or all remote controls. i think this will be a standard feature on all tvs eventually and perhaps this will ease the fear of folks who are worried that a public tv can be turned off by “someone”. every bar, restaurant, public space will be safe and controlled.",

In the last few days, rooting the T-Mobile G1 and myTouch 3G has become much easier. [Zinx] released FlashRec which lets you flash a new recovery image onto your Android phone. It takes advantage of Linux kernel vulnerability
CVE-2009-2692
. The app lets you backup your current image and then flashes Cyanogen’s Recovery Image 1.4. Once that’s done, you can use any custom Android build you want. Android and Me has
documented the entire process on their site
and points out the
ridiculously large number of custom ROMs
that are out there. Embedded below is a video from [unknownkwita] showing the rooting process.

Inspired by the multitudes of other automated window blind projects, [John] decided to
build his own simpler design
. Knowing his Arduino was massive overkill (yes, we hear you all cheering) he picked up a picaxe 08m starter kit. Looking at his very simple circuit, you’ll notice there are no resistors or capacitors. He designed it to take commands from his PC via IR. The final product is fairly well hidden, and should his girlfriend ever be upgraded to wife, we assume he’ll hide it better. Good job [John]. We’re no strangers to
automated blinds
, we’ve
seen them
a
few times

Surprisingly the Xbox 360 hasn’t seen a lot of homebrew action. [tmbinc] has taken it upon himself to
port the Snes9x emulator to it
. There’s no pretty GUI, and its not running on top of linux or anything. This is native, directly to the hardware emulation. He believes this is the first to do so. Unfortunately, it will not work on the most up to date Xbox 360s.

This has been a major problem on the original Xbox homebrew scene, where most scene releases were “illegal” because they contained XDK code. Most people don’t seem to believe that xbox software development can be done without Microsoft’s support, and my snes9x port (it could really be any other program as well) is basically the proof that it can be done.So the real thing here is libxenon, a free library with xbox 360 hardware support. Snes9x is just a random app which was ported to that library. I did the video because people were bitching “it will take ages until we see real homebrew”. Well, it did not.",

Which means (per this demo) his 360 probably BOOTS to the emulator and that’s all it can do. Basically, he turned his 360 to an SNES. This is less than useful for most people.The main reason we haven’t seen a lot of mods for the 360 isn’t “security” but because of it’s weird pseudo-PowerPC architecture (Xenon) that isn’t fully documented and it uses a proprietary controller interface. The PS3 also has a weird pseudo-PowerPC architecture but it IS well-documented, they provide low-level APIs, and they use standard interfaces like Bluetooth. This is why Linux on the PS3 actually works and why you see more homebrew.The original XBOX was essentially a standard Intel x86 PC with very standard interfaces. You could run Windows on it and a vast variety of Linux variants. The standard x86 architecture made is VERY easy to port AND Windows or Linux software for the original XBOX, which is why so much is available.It is very unlikely that ANY console will ever be as good for homebrew as the original XBOX was. So hang onto ’em.I also strongly recommend the PSP for this kind of work. Running old SNES games on your 360 is “eh”, but it’s a lot more compelling on a handheld like the PSP. Basically, as far as emulator boxes go, the current winner by far is the PSP and possibly the upcoming OpenPandora.",

[Dennis] points out that the iPod shuffle and the iPod remote are almost identical visually. He decided to
combine the two
so he always had his remote with him. He pulled the guts out of a remote and mounted them in a shuffle. The remote functions all of the time, while the shuffle only turns on when you insert headphones. We wonder if he accidentally does stuff on his computer while he’s changing songs.

[Harandi] wrote to us to let us know about a project he’s working on to improve our nightly rest.
This is the Happillow
. The Happillow is an alarm clock, as well as a snore relief system. We’re not sure that the snoring bothers us so much, but we’re sure our significant others appreciate that part. 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. The Happillow detects the noise and agitates you to get you to reposition yourself. We have actually seen a very similar project in the past with the
Interactive Pillow project
.

So about 252mA maximum. using 2500mah nimh batteries this practically has to work for 10 hours.But display only runs at maximum intensity under bright sun/lights. With lower ambient light it fades the intensity (completely off during the night). Now it can work for a full day and night. This can easily be tripled with putting the leds in series (easiest modification).And still there are some more room for improvement . Suggestion of having a wireless power source for charging is also considered in future work.",

Theres an interesting thread going on at
RoboterNetz.de
(
translated
) about building delta robots. For those who haven’t seen delta robots before, be sure to check the video after the break for some really impressive agility displays. 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].

To make matters worse, unlike simple X/Y machines, its strength is variable throughout its operating envelope.Accuracy for light loads (low mass) can be excellent (with the right actuators, sensors, and software).Difficult for ‘profiling’ (as in CNC path following) as the math involved to transcribe a simple XY motion to the three motor actuator is pretty complex algebra (possibly some calc)And, in the post, you don’t really mean ‘level.’In the case of the video shown, level is the vertical displacement of the effector within the operational envelope.you mean that the ‘orientation’ of the end effector always stays consistent. In fact, without some really difficult math, the ‘level’ of the end effector is never consistent… more like sine waves (it bobs high near the middle, and low near the sides of its envelope. in order to make it move a straight line, you would need to be able to calculate and output 3 dimensional sine wave profiles to motors. Tracing complex curves becomes even more difficult.pick and place works great though, since you dont care about the path, only the pickup point and the drop off point.

That is why machines with high tolerances, and high price tags prevail, that IS their advantage. We on the other hand are really very good at being inaccurate, and can adjust the trajectory of our limbs mid path at very high speed in order to achieve our goal. that is why humans are so much faster when accuracy isn’t the goal.http://www.youtube.com/watch?v=dSBe1fNfOjo",

Not optimal for cnc.MRE- Great observations, though kinematics for this were simple trig, trajectory generation (path-planning) can be standard trapezoidal method, or G-code, but JensOverby (check his youtube channel) has a dynamics based trajectory planner that is even over the head of the ABB flexpicker engineers!kgartner- uh-oh, a serious PKM guy. My friend Ilian Bonev has just finished the first textbook for these mechanisms “Fundamentals of PKM’s”. It is good brain food for us.Dan and Nuke- I’ve made @10 different versions of this mechanism for Delta Tau, they always show them at the conventions. Some slower, some faster, some bigger, but all with different controls/amps/motors.KermyNZ- Industry is researching this, but the only reason industry is looking at these for laser/waterjet/plasma is due to cost (no bearings). Honestly, anything away from fast/light/faster/lighter begins to move away from the true strengths of the mechanism.DY- exactlyIn a nutshell, 10-15g’s of acceleration is the key to these, with cost and workspace close behind. No where else will you get 160 pick and places per minute over a 1m workspace for @$15k cost. Period.Glad you all liked, this is a growing field, very cool to be involved.Jamison",

Logging Weight Changes

This is a classic example of a well done hack, simply for the sake of hacking. [Jorge] wanted to be able to chart his weight changes. 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
.

Another switch (mosfet) in parallel, is controlled by the LPC2103 and turns OFF the system just after it writes the data on SD Card (because original scale turns off before system writes data to SD Card).Please leave more questions and I can help if someone wants to build that system.Ah, and I went to market and bought the cheaper digital bathroom scale for making this projects. Looks to me that every scale are equal, they have the same number of digits and just behaves in the same way. They are probably from the same Chinese sources.",

[Jared] wanted to do something monumental to commemorate his late father. His idea was to
take this organ console and convert it to a digital beast
powered by
Hauptwerk software
. The project is slated to take 18 to 24 months to complete, at which point he’s going to donate it to his church. You can follow along as he guts it and replaces all the mechanicals with new parts to interface the computer. He also finds that he needs at least 42 individual speaker cabinets to achieve the sound he wants. This thing is massive, we would love to see it in person.

Those 32ft pipes ain’t small….. Then there’s sourcing the 1930’s parts, bakolite, leather and relays anyone?My Father also installs virtual theatre pipe organs, does a lot of work with hauptwerk, either hooked up to original consoles or midi keyboards. All of his customers are heavily ‘into’ pipe organs and making the sound proper (hence the 42 speakers as well as decent soundcards to run it all), sometimes this is the only way to ‘save’ the console for the greater good as these things get neglected due to the high running costs/time to keep them maintained.It’s the guys console and his Fathers memory, I say let him do what he likes. There’s very little actual hardware in the console itself, a few hundred relays for the keys,tab stops etc. and a electric/mechanical box which does all the signal routing and stores presets in ‘memory’, not far off what an ‘arduino’ can do, well, apart from be reliable like an arduino …..It’s a mammoth task that he’s taken on and having worked on compton and wurlizter organs myself, I’d be more than happy to gut the innards of the console at least and drag it screaming and kicking into the reliable 21st century.",

Battery life is often overlooked when building projects, especially for beginners. This tutorial takes you through the setup of
power saving modes for the Arduino
. Utilizing the watchdog and sleep functions, they put the chip into a hibernation mode between cycles. An optimum configuration could take your battery life from 4 days to about 3 years. For a lot of you, this is old news. But for the rest, this is really good stuff. You can download a sample application from the site that mimics the singing of a nightingale when the sun goes down.

"content": "The atmegaX8 series (like the atmega168) have a useful feature to get accurate periodic wake up and sleep operation.You run the AVR on internal oscillator, I choose 1 MHz and change the clock divider to 4MHz so it will operate from 1.8V to 5.5V.You connect a 32KHz watch crystal to the crystal connections of the AVR. Dont forget the load capacitors.When you turn on timer 2 in asynchronous mode, and enable to use the crystal oscillator. You can go to power-save mode where most of the controller is powered down, but the timer 2 interrupt will periodically wake the AVR up.Using the interrupt of timer 2, and the proper divisor you can wake up 1024 times per second. Useful for a small operating system scheduler.I use this setup in a small wireless sensor network I am developing. I need a quite accurate timer to have reasonably accurate synchronisation between nodes. It is not really needed but improves power efficiency.",

[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.

Go to
this site
and you’ll be greeted by a crazy looking woman wielding a giant egg and a blunt object that looks like Jupiter with mischief in her eyes. This is Tatjana van Vark. Her library of projects ranges from the mundane such as a couple of incandescent lamps, to a fully functional
Antikythera mechanism
. As you browse around at things like her
one of a kind cipher based on the enigma machine
and her
inertial navigator platform
shown above, you’ll find the quality of her work astounding. Randomly peppered haikus give us a brief glimpse into her mind as we look at, literally decades, of amazing work. We’re sure many of you are drooling at the thought of some build details, but you’ll have to work for it. Decipher the haiku on the coding machine’s page for the build details… if you can.
[thanks Verimius]

This means, it will happen in a future, where all these things have been lost, because they are not known to “common people” any more. Think of giant 100% robotic plants driven by artificial intelligence that does all the engineering as well as the construction work. Nobody takes things apart any more, because it’s easier to find out how they work by looking at their software (and because they can’t be taken apart without destroying them – we’re almost there already). This will be the time when the art of someone like Tatjana van Vark is going to inspire people, to go a different way (re-integrating knowledge and genius of the past into the then-present day and future).",

Pulsar Professional FX has a neat tip on their site for
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
.

As soon as I went past the point of “tracks between 0.1in pitch DIL pins” I started having trouble.I switched to photo-etch earlier this year (using a Mega Electronics 8-bulb double-sided exposure unit with a vacuum system built in) and I’ve gone from having a ~40% success rate on fine-pitch SMD to nearly a 100% success rate. I think it’s actually working out quicker (for me) to go from CAD to a photo-etch PCB, and it’s certainly less effort to do double-sided boards (a photographic lightbox is a BIG help here, as is a roll of B&Q foam tape to hold the transparencies in alignment).FWIW, I’m using the Jetstar acetate, a Canon iP4600 printer, Mega’s own “Microtrak” laminate (but the CIF stuff also works OK) and the Seno roll-on developer (because it’s easier than setting up the developer tank for a 30 second dunk).Put simply, it works for me…(If you’re going to do this, it’s also worth getting a step gauge and setting the exposure properly…)",

Most people would only have to buy blank PCBs and etchant (very cheap) for a simple toner setup.Each method has its strengths and weaknesses.– Toner: cheap and easy setup, low per-board cost, can be time consuming and frustrating especially on small clearances (good equipment helps a lot).– Photo-etch: better resolution without much practice, but setup cost and per-board cost are higher.– Inkjet: fastest processing time by far (hit print, bake for 5mins, etch), quite high res., per-board cost is low if you buy ink in bulk. Initial setup however can be tricky (pcb alignment, timing issues, etc.)– CNC: highest setup cost, very low per-board cost (depends how long your bits last), slow for complex/large boards, but can give you the most complete product (edges routed and holes drilled). Average resolution.(these are generalizations from my experience with a low hobby budget)",

Regular submitter [Jared Bouck] from Inventgeek.com has sent us
this cool project
. He wanted to make a fireball cannon, but didn’t want to settle for plain old fireballs.Instead of using a common propane system, he built an alcohol based one so he had a “blank slate” to start with. He then applied some copper chloride to get the desired greens and blues. With all of the fire displays we see, how come we don’t see more colored flames? Check out the overview video after the break.

Have you ever wanted to see what it’s like
inside of a PCB assembly factory
? Have you ever wondered how
digital storage oscilloscopes work
? If so, be sure to check out the
EEVblog
podcast. The Electronics Engineering video blog podcast, hosted by [Dave Jones], was created for anyone interested in learning more about electrical engineering. While some knowledge of electronics definitely helps, [Dave]’s thorough explanations and firsthand knowledge in the field of electrical engineering make the video blog easily accessible to beginners in the field. The EEVblog covers a wide range of electronics related topics, offering everything from
multimeter reviews
to
GSM mobile phone audio design advice
. In the latest episode (shown above), [Dave] discusses and demonstrates how to solve the infinite resistor problem, involving measuring the resistance at different points of an infinite grid of resistors that all have the same resistance. In addition to giving a detailed explanation, [Dave] created a 14 x 14 grid of 420 10ohm resistors to demonstrate how to solve the problem. While we’ve only mentioned a few episodes here, be sure to check out all 25 episodes of the
EEVblog
podcast and subscribe to the
RSS feed
so you’ll never miss an episode.

Robert Crumb
], the celebrated artist who created the commonly recognized
keep on truckin
,
Fritz the cat
, and
mr natural
can be seen here doing a ghetto hack. His record was warped, so he had to
melt it in the oven to flatten it out
. While [R. Crumb] may not be the epitome of celebrity and wealth, he got us wondering, what celebrities do ghetto hacks? More importantly, what ghetto hacks do you continue to do, even though you could afford to just simply replace the item? In case you missed the ghetto hacks thread,
here it is

To pull a prank on. See sense 2 and hacker (sense 5).6. vi. To interact with a computer in a playful and exploratory rather than goal-directed way. “Whatcha up to?” “Oh, just hacking.”7. n. Short for hacker.8. See nethack.9. [MIT] v. To explore the basements, roof ledges, and steam tunnels of a large, institutional building, to the dismay of Physical Plant workers and (since this is usually performed at educational institutions) the Campus Police. This activity has been found to be eerily similar to playing adventure games such as Dungeons and Dragons and Zork. See also vadding.Constructions on this term abound. They include happy hacking (a farewell), how’s hacking? (a friendly greeting among hackers) and hack, hack (a fairly content-free but friendly comment, often used as a temporary farewell). For more on this totipotent term see The Meaning of Hack. See also neat hack, real hack.Note that only one of those specifically mentions a computer.",

Jew’s Lane) known as the Jewish Quarter.HistoryThe term came into widespread use in Ghettos in occupied Europe 1939-1944 where the Jews were required to live prior to their transportation to concentration and death camps.The definition of “ghetto” still has a similar meaning, but referring to broader range of social situations, such as any poverty-stricken urban area.A ghetto is formed in three ways:* As ports of entry for racial minorities, and immigrant racial minorities.* When the majority uses compulsion (typically violence, hostility, or legal barriers) to force minorities into particular areas.* When economic conditions make it difficult for minority members to live in non-minority areas.",

I think most people here do, it just seems wrong somehow to fork up for a new one even when it’ll take an hour to fix an item that costs much less then you’d invoice your employer for an hour of your time.I think “hack” has a very zen kind of meaning that kind of spans all of the above – something clever, useful, productive (to your side) that isn’t standard. “Ghetto” has taken on it’s own meaning since WW2 and I think it’s a nice prefix for “cheap, sloppy and very functional”. Yesterday I ripped the cover off the grass exit to my sons lawnmower, flipped it over and rigged it with a clothes hanger and a piece of fishing line so that it would blow grass out (rather then jam) but not straight up at the user as he had rigged it. That’s considered “Ghetto” – using crap that’s around for free anyway to accomplish a goal when combined with some brains that otherwise would require more. “Hack” certainly has an air of this and respect it, but extends the same principle to levels that can involve more complex equipment.",

It might be a little bit of overkill, but this
etching container agitator
sure looks convenient. There’s not much to it technically, a small circuit with an ATtiny45. For those beginning with this stuff, he has written a pretty good tutorial on
working with basic microcontrollers
. If you are more interested in a tutorial on etching, we did a guide on
how to etch a single sided PCB
.

Building An Apple 1

With all the recent talk of hackintoshes going around, we thought we should post this oldie. It is a writeup on how to
build your own Apple 1 called Replica 1
. If you’ve got the $149 laying around and think you can handle the construction of a mere 88 components, you can make one yourself. Not only can you order kits or complete units, they even have a download page with applications and games. It might be fun to have one of these sitting on the desk right next to our
minimac
. If you really don’t want to buy one, but maybe want to just play a little bit, there’s always
virtual apple
.

IMO it’s like having a paint by numbers copy of the Mona Lisa instead of a high quality print.",

"content": "I’ve noticed there’s three main categories of negative comment on these types of sites.“This is old.” or “Repost.” Typically generates disdain for the person who posted the article, usually proportional to the wide-eyed enthusiasm for the project, also proportional to the age of the project. The negativity is rooted in the feeling that the person posting on a website should be at least as familiar with the culture as the readers.“This project sucks.” I’d say that, in most cases, you see this type of comment when the project actually does suck. I remember seeing a lengthy howto (not here) on a “free battery holder” which consisted of taping them together. Duct tape and cardboard is cool if it’s used creatively to solve some actual problem, or displays some skill. Projects that consist of an LED and a battery used in a non-creative way are pretty boring.“You suck.” A direct attack on the person who posted the article, sometimes not related to the project at all. A lot of spelling errors, or making some comment about the project that is either blindingly obvious, over-enthusiastic, exhibits ignorance, or tries to tie the project to something totally unrelated. Basically anything that gives the impression that the poster is “not one of us” or “is too lazy to research” or “can’t even spell correctly.”There is a lot of over-reactive negativity in comments, but a lot of it does have a valid cause. Authors can reduce it by getting more in touch with the audience and paying a little more attention to what they write. Don’t ignore what someone is saying when they are being negative…they might be right. It’s the audience telling you what they want to see, if you ignore that, they’ll just leave.",

"content": "one thing that annoys me about hackaday comments is the blatant HATRED of Arduino.From Khordas (above):“Greater internet dickwad theory: Normal person plus anonymity plus audience equals total dickwad. That and one two many arduino projects by hackers who don’t have clue #1 about what a microcontroller can do.”while i do agree with the equation (normal person + anonymity + audience = dickwad, with regard to ‘agressive’ comments) i couldn’t disagree more with the rest of the comment.READ (a few times if necessary):“The goal of the Arduino project is to make available accessible tools that are low-cost, low capital investment, flexible and easy-to-use for artists and hobbyists who might not otherwise have access to more sophisticated controllers requiring more complicated tools.”– from wikipedia, via the Arduino siteWith these goals in mind, the arduino is quite obviously a success.I fall into the artist/hobbiest crowd and the arduino has opened the door to the world of microcontrolles for me through its accessibility, abundant documentation, low cost, and great community. (does that make me a ‘fanboy’?Before reading further please note: the description above does NOT list engineers as the “target audience” for the arduino.engineers (and the like) seem to be ANGRY that Arduino provides the ‘everyman’ an open door to microcontroller technology and it pisses them off. assumedly, because before arduino they(engineers, etc.)were the only ones that could harness the power of microcontrollers through the knowledge they gained via specialized education. now anyone that wants to use microcontrollers can, and it makes them feel less special – so they lash out and make fun of the ‘lesser’ microcontroller and projects made with it.its called elitism. pure and simple.",

"content": "(posting this a second time)There is a stark difference between the comments on “hacker” sites VS other sites. This isn’t just the Greater Internet FWad Theory in action.I think part of the appeal of hacking is “secret knowledge” and/or “superior knowledge”. As a hacker, you know how systems work, or at least you think you know. That is the most valuable knowledge you have and what sets you apart from the sheep. That, plus with the necessary confidence/arrogance it takes to rip the mainboard out of something or code up your own solution to a probably-already-solved problem, times the many hours of non-social time with machines, equals brusque and rude behavior.What I find so sad about the hacker community is the attitude about knowledge is often shit. Years ago my acquaintance Ethan got busted for hacking his ISP with some old sendmail bug. Ireallywanted to be as good as him with software, and I knew that he could teach me. I asked him what I needed to know to get started w/linux (1996, btw), and his answer was “More than I’m gonna tell you.”. Classic “hacker” dickface move. RTFM, or whatever. I took to phreaking instead.That’s why the only hackers I respect are the ones who are out to share information. We all started somewhere. It’s the reason why my book scanner instructable is 79 steps long and carefully illustrated. I could have written it with a few shty, blurry webcam pictures and a couple terse sentences of arrogant text, but I want people to be scanning books right along with me. In fact, of the dozen or so people who now have built one, many had never previously touched a soldering iron. For that reason alone, the effort was worth it. Not to mention that I won a laser cutter.Not only that, it makes all the aggro comments (79 steps!! OMG!! No Page Turner!! WTF!!) look really stupid.Finally, all hacker types that I know think they can do anything (and they kind of need this to be bold and try stuff, it’s a combo vice/virtue), and I think they’re all a little bit shamed when they didn’t do it first… so they have to “know better”. Hence the aggro comments on how somebody did something wrong. Funny thing is, they did it first. Being expedient is often way smarter than being correct. The idea is not to make one perfect hack, but to get the goddamn work done and get on with your projects.Hackaday is one of the perfect platforms to change attitudes like this. Just look at all the people who have put up documentation at the request of the community. I wish I had the time to write for HackADay to help encourage this, but at the moment I’m at the late stage of a Masters’ in neuroscience, so I won’t have enough time. Good luck, gentlemen.",

While researching solid state Tesla coils
we stumbled across this old project
. As you have probably guessed from the pictures, this coil is meant to actually play music. Knowing how to add eye catching flare, the coiler uses a Plexiglas frame turned light pipe; only to be complimented by an audio amplifier complete with graphic equalizer. There is a
video of the coil in action
on YouTube. We have covered
singing tesla coils
in the past. Other twists on the classics include the
tesla coil guitar amp
and a
hand held plasm gun
.

HackTheBadge 1.0
|
Caleb Kraft
|
[
"Wearable Hacks"
] |
[
"badge",
"defcon"
] |
[Martin] tipped us off to
HackTheBadge 1.0
. Possibly more elusive than the
NinjaBadge
, HackTheBadge has a Dpad, a 3×5 LED matrix, Arduino compatable headers, and 46 GPIO channels. You can download the open source plans if you didn’t get one at Defcon. You probably didn’t, there were only 14 given out. You can also order one pre assembled. This makes us wonder, does being low in quantity qualify this as elusive?

UPDATE:
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
.

That is pretty darn cool in my opinion.Check out:http://www.obdev.at/products/vusb/projects.htmlThe hacks are “arduino based” because the Atmega chips are so cheap, powerful and plentiful, the arduino is just a PCB with easy prototyping features, power supply, RS-232, USB etc. I personally find “arduino” over-priced (I am quite poor, and a tightwad), but I like a rats nest of wires and my solderless breadboard, which I move to solder breadboard when the circuit is tested.This project doesn’t seem to use Arduino, but a neat one to check out with an Atmega chip is this two-chip and some resistors game console!http://belogic.com/uzebox/howitsmade.htm",

DOSbox On Zipit

Who out there has a Zipit? Great, now out of the five of you, who really wants to run Dos on it? Well, for the one or two of you left reading, now you can.
The directions can be found here
. [Hunter] has worked out a way to get DosBox running on his Zipit. At 315 mhz his old DOS games, like AD&D shown above, are running quite snappily. You can download everything you need to get up and running from the site. If DOS isn’t your thing, you may want to check out the
Linux how to
as well.
[thanks Harold]

They also include “unlimited texting” with the plan – but seriously, all that is is email to SMS.Zipit just gets me a touch annoyed at the fact the device requires of all things a frickin’ service plan for a kids toy.Also, on the side, the link Hack-a-day posted for Linux on Zipit is for the “series 1” Zipit. The Z2 actually runs Linux out-of-the-box. (http://www.linuxfordevices.com/c/a/news/linux-im-pad-beefs-up-invites-hacking/)Despite all that, Zipit does have one of the most thorough sites full of documentation to get Linux running on the beast –http://linux.zipitwireless.com/",

[Pocket Lucho], the builder of
mini arcade cabinets
, is back with another build. This time it’s a miniature
Neo Geo arcade machine
(
translated
). The build is very compact and neat. He attached the control panel and the PS one display using magnets to make the wiring more accessible. It has video out and second player input too. You’ll find an assembly video embedded below along with a trial run.

The Applied Sciences group in Microsoft Hardware have come up with an interesting tool. This is a
pressure sensitive keyboard
. Our minds went strait to gaming, as theirs did too apparently. They show how this could give you more control in your games based on how hard you push the button. Remember the first time you got to use an analog stick, it sure is hard to go back to a D-pad. We want to know when we’ll get to play with these
cool toys
made by Microsoft.

(I have a Saitek Eclipse II which isn’t too expensive, but you can get keyboards for like 5-10 bucks)Maybe the keys are really mushy (they don’t have that click) so they figured people wouldn’t like it for typing.

The folks at SparkFun were startled by how small USB bluetooth adapters had become so
they split one open
. They noted a few interesting design features. It has a small folded trace antenna on the board edge. The metal USB housing acts as the RF shield. The bluetooth IC is an AS3620QA. Now we wonder what those
tiny Buffalo drives
look like inside.

The latest Inventgeek project is a 12 outlet control box. They decided to demo it using a
giant bulb based VU meter
. The control box has 12 individual outlets hooked up to two layers of six solid state relays. [Jared] notes that SSRs can be very expensive, but he purchased his on eBay for ~$10 each. Wiring and installation on this project is incredibly clean and they plan on using the control box for future how-tos. The simple audio circuit used for the VU is based on the LM3915. You’ll find full plans on the site or you can watch the overview video embedded below.

The Big Picture is Boston.com’s daily news photo blog. Each day they pick a particular story and feature some of the best news photography around. Today they chose robots and have
36 photos highlighting current robot research
. This is a followup to a
similar post from March
. It’s interesting to see all the different forms and tasks robots are taking.

[Kenneth Maxon] is a wizard who only does things one way, beautifully. While out of the average hacker’s production capabilities, his
injection molding machine is amazing to behold
. The machine has all features a commercial model would. It heats and cools the mold, produces over a ton of pressure to inject plastic with, and ejects parts automatically to name a few.

I mean like split second, that’s why your injection time is so tightly controlled on the real thing. No, heating the mold with water won’t work either, although it will help but not much. I give the guy credit for the effort, but this isn’t going to go off as planned. Injection molding machines aren’t all that expensive nowadays anyways. Certainly, he could have bought a used, small, working machine from the 70’s or 80’s for somewhere near what all that aluminum and machine time alone. That time making that could have been spent making molds for the real thing.",

AVGA: The AVR Based Video Game Platform

We’ve seen our fair share of
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.

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?

It was pretty awesome to see the strands of cable slipping in and out of the creature’s solar plexus.

I would want THAT robot to be more human looking… and something like a DATA-like capability. The robots from I, Robot for example would not be good enough for me for caregiving. Nor would I want there to be any wireless connectivity.smileThe I, Robot level of human like appearance would be good enough for me for service workers and possibly hot dog cart type vending. But it’s just too cold of a style for human connection.Just like with pets given to the elderly, there are a lot of plastic ones that don’t work well, but the fur covered ones to. The tactile feel of something ‘real’ goes a long way for human connections.@therianYes, we’re not at sex toys yet, but that’s what I was saying about the purpose of the robot. Right now it seems that a lot of robot projects are really a shotgun approach. Meaning that they don’t really have a refined purpose in mind, they are just proof of concepts. Which is great I think, to further the thought process and experiment with different ideas.When one makes a robot with a specified purpose though, I would agree that nothing matters except efficiency and other technical factors for service robots (i.e. robotic welders in a factory). But if the purpose is human contact in a care giving role or something similar, then I think acceptance of the robot is more important than certain function and design issues.For human contact, it won’t matter how perfect the robot functions if nobody ‘likes’ to hang out with it.",

He looks totally artificial and moves the same way, but he is still charming, because you imediatly know “thats a robot” and not some dug-up half-decayed fella with a battery up his ass.

"content": "@8-[I can see your point there. Seeing a robot act strange can be taken in stride while seeing a human act strange is just… strange.I agree that a ‘real’ DATA isn’t reality, probably in anyone’s lifetime. And even if it was, by the time THAT tech comes around I think it would negate the NEED for such a thing as a life-like robot. If we had that massive computing power and that kind of tech, we’d certainly have replicators and the like so service personnel would probably be un-needed.We’re probably looking for a solution to a problem that doesn’t exist though. I mean, I don’t think the majority of the world would accept a robot taking care of children (although maybe we’d be ok with them taking care of the elderly). If we did get to that point though, I think it would take several generations to come to pass. It wouldn’t be as fast as my kids accepting it and so it’s OK from then on. And because the hurdle for acceptance of the idea of robots being trusted to be caregivers is so high, it probably doesn’t matter what they look like. The perfect example may come out, but we’d still be scared of it for quite a while. As we should be in my opinion.I’m completely on board with robotic vendors, maids, truck drivers, etc… robotic driving built into cars on the highway (not cities) too.The only concern with all that robotic replacement is job loss, but I have to think that we could manage that because those robots will need maintanence, oversight, and construction. So even though those jobs could be lost, new jobs would be created. Probably not an equal number, but I believe that any such conversion from man-power to robot-power can be done well if it’s handled correctly.Can we as a people be trusted to do it well? that’s a debate that isn’t worth having because history teaches us that we should not be trusted with such a thing. But we should be able to do it.sighIn any case, I can’t see us really having to figure all this out for at least a couple more generations. They already had ‘working’ robot truck drivers and that went away for a number of reasons un-related to the tech working or not. I just don’t see us as a society being ready for robots to move out of the lab any time soon. Which is a shame on some levels… and maybe a good thing on others…",

Once they’re accepted though, to go from servents to ‘free’ beings and be treated as such… we’d be on the same song, second verse.I really don’t think we’ll have to cross that bridge though.I think an honest most likely path for us at least in the next 2-5 generations would be for us to be able to produce a vendor role robot and have it in service possibly at places like toll booths or other remote type outposts as well as vendors of food and goods like airport shops/news stands and the like. I don’t see robots replacing anyone we might have a conversation with now, but those people behind counters that we ignore for the most part, those roles are prime robot fodder.And I wouldn’t really feel that bad either, because those people don’t want to be there either.I would hope that we are able to add robots in some roles without destroying our employment rates though.I can see it now though. Right now where you have a company with 10 people on staff and feel shorthanded, I could see the ‘media’ blaming robots for the ‘loss’ of 5 jobs if that same company added 5 robots where they would not have added 5 humans due to overhead costs like medical insurance and taxes.Similar to how RIAA counts a lack of growth as a ‘loss’. “we were supposed to increase our profit by 200% this year, but we only increased by 100%. Therefore piracy has stolen 100% from us!”I’m sure the politics of robot workers would get in the way of intelligent integration regardless of how much logical sense it might make.",

I had forgotten about that term, but that’s exactly what we’re talking about.The challenge becomes figuring out what roles we really think will ultimately be acceptable or not in the foreseeable future. And whether or not those roles suffer from the valley.For vendor roles, I would think that as long as it’s clean, us humans would accept any sort of robot even if it does suffer the valley. Because we’re not spending any time with it really, just paying for something and moving on. But a waiter at a restaurant though, since we have to establish some kind of repor with them and most of us generally enjoy the interaction, this role would either have to be so perfectly human as to fool us for the most part, or blatenly robot.A robotic waiter though, I think would degrade the experience of most diners.

The thought process here is whether to mimick a human’s layoutexactlyfor the purpose of us accepting it more (or some other purpose?). Would that even be needed? Or is the best aproach to go with whatever design is more technically efficient? In my opinion, I think the role of that particular robot determines the answer to that question.Another angle… does it make sense to impose our limits on a robot simply for the purpose of mimicking our layout? Ever tried to scratch the middle of your back? Possible but annoying. I don’t think it makes sense to make a robot that has that same limitation. there’s no reason to impose that limit on them when we have the choice to make sure it can reach and work on every part of itself if needed. (we’d certainly want a soldier robot to be able to remove a sticky grenade from it’s back if the case arose, right?)There are a lot of fine points to this discussion, which is what makes it so facinating, and I’m sure people all over the world in robotic labs are talking about these same things.

The range of movement more than make up for that.As far as A.I goes, I don’t think the problem is computer power. Already computers are so much faster than the human brain. The problem as I see it is that computers just don’t work like the brain does. It’s a completely different model and no matter how fast computers become, they’ll never mimic a human brain on the development path they are going down.To get a robot with a brain as good as a humans is going to require a whole new way of looking at computing. The brain is massively parallel. It’s like having millions of computers all working together, each one really quite dumb but taken as a whole, amazing things are realised. We aren’t able to create computers like this yet but were taking early baby steps with more cores.I’m a little more optimistic about human like robots appearing sooner rather than later and at costs that make mass production possible. We just need to hit that tipping point where the framework is there to build into. Right now there just seems to be a field of ideas and experiments and no real anchors to start creating a framework to realise this. Maybe the first anchored moments will happen soon, maybe in 100 years, I can’t predict that but from what I’ve seen, it seems like robotics is starting to gather some real momentum, and the commercial applications may be what are driving that so hard now.Anyway, enjoyed reading the comments here almost as much as the video :)",

In 2006, Defcon 14 premiered a unique electronic badge.
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.
UPDATED:
Forgot to mention the
Neighborcon 2 badge
based on the
GoodFET20
.

I’d also bury backdoors into the device, through any available interface (IR, LEDs, sound?), to encourage malicious (fun) hacking of other participant’s badges.Given the small number of hardware hackers and the short length of most CONs, I’d probably design a badge around an Arduino. Don’t take that to mean I’m a huge Arduino fan, but it might be an appropriate solution in this context. There’s lots of free tools and example code, and beginners just need a laptop and a USB cable to get started.For hardware, a cheap IRDA transceiver gives wireless access without regulatory issues. IRDA could be used for the interactivity and tracking suggested in previous comments. Use your unique IR identifier to register and gain entrance to parties? Leave a IR bootloader backdoor open for taking control of other people’s badges. A cheap SPI EEPROM or SRAM (or both) for logging data, perhaps spying on other people’s credentials or creating a contact list that can be read at a kiosk.

Your badge connects over bluetooth or rf and has an LED for sex/age/relationship status/etc. Friend request? it updates your social networking site of choice and adds the person standing next to you. Think he/she is hot? See if they’re single ect. Maybe not such a “hack” idea as the “next generation of social networking” but it is an idea that just will not leave my head.",

Also a points system with prizes at the end would be cool, the more you attend certain events the more points you get. and it needs a color screen. color screens are so cheep now, why not put one in a badge. i was thinking about the virus idea thinkhttp://xkcd.com/350/but with peoples badges insted of virtual boxes.",

[Alexander] sent in his entry into a “creativity contest” at his university. He and some friends put together this
dry ice cannon
. Take note of the creative mechanism they used to mix the water with the dry ice. A large amount of gas is expelled as soon as the two begin to meet. If the gas is supposed to escape through the same opening, it is difficult to get all the material through. They have added a second opening just for the exhaust during mixing. Great job guys. How about some downloadable plans.

[Shachar Geiger] sent in an interesting project that he worked on with [Tal Avivi] at the Bezalel academy in Jerusalem. They were given the task of designing a 1-person electrical urban vehicle. They took some cues from
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.

A little over a year ago [Ian Lesnet] joined our hacking team and began cranking out some of the best original how-tos Hack a Day has ever offered. You may remember our popular
web server on a business card
from last fall and we’re sure everyone is familiar with the
Bus Pirate
(yes, they’re still
on schedule
).
It’s a year later and he’s found himself with less time to contribute. [Ian] is stepping down from blogging at Hack a Day, but you’ll find him right where he started: in the comments. You can also reach him directly on
whereisian.com
. [Ian] will be continuing to develop the Bus Pirate. You’ll find the latest info on the
Bus Pirate’s Google Code page
. He’s also posted a
guide to the on-board pull-up resistors
as well as a self-test guide that uses the new v2.0 firmware to
confirm your Bus Pirate is working
.
[Ian]’s contributions will be greatly missed. We’re always excited when we add contributors of his caliber to our crew.

[Andrew Rapp] sent in this project called
Droplet
. He’s been doing work with Xbees and Arduinos together and built this little toy. He describes it as “sort of like a Chumby”. It has built in services for Twitter, Google Calendar, News, Gmail, etc. You can download the full source code and plans on his site. His next planned revisions include possibly running it from a
sheevaplu
g, making a nice case for it, and utilizing the unused pins of the arduino.

Recently, analog displays have come back in vogue. This is partially due to the common steam punk theme that is popular right now. [Cristiano] has done an analog display, but instead of brass and polished wood,
he’s gone automotive themed
(
Internet Archive Cache
) with it. He purchased a cheap tachometer from ebay. A circuit had to be designed to give the tach the signals needed for it to operate, and you can download the schematic from his site. As you can see in the video above, it works well. We think that “shift” light might get annoying pretty quickly.

I have a mixture of digital and analogue displays on my workbench to cover different needs; digital is more accurate, but analogue shows trending and signal dynamics better.USB is good. RS-232 is good. Centronics printer ports are good. MIDI is good. RS-422/GPIB is good. Using the joystick inputs is good. Using the speaker output is good. It’sallgood if it does what you need without fuss or complication. My workbench ‘puters are typically old AT’s or whatever running DOS or early ‘doze, and they are still very useful for the specific tasks I set them up for. Laugh if you like, but if I do happen to accidentally put the mains up the printer port it’s only a minor matter to chuck it and swing in another one.But sometimes I have to wonder about the application of digital smarts, and wonder how long it will be until I see acrowbarwith 32-bit micro and LCD display.There’s nothing wrong with hanging over the bleeding edge, just don’t assume that because a particular technology isn’t the current flavor of the month that it’s automatically useless. 3.5 floppies are on the way out and that creates some serious problems for me because they are variously ideal for some needs, and indeed vital to keep some music synths going.There are valve (tube) guitar amps out their still gigging strong after 40 years, yet a modern amp or mixer that uses some modern but now outdated tech (e.g. 720k 3.5’s) is reduced (very) prematurely to junk. I think SD cards are magic, but I’d think very carefully before committing to anything that depended on their long term availability.To my mind a good hack comes from keeping as many options open as possible thus multiplying the possible combinations. Do we turn our noses up at a 270 degree moving coil meter as a display? Or do we recognise that some old tech like this is hard to even equal using an LCD and 64-bits of digital crunch?",

These Autonomous Underwater Vehicles are all competing in the
12th annual AUVSI competition
. They have to complete an underwater obstacle course that involves some tight maneuvering, retrieval of a briefcase, dropping bombs, and firing torpedoes. We’ve
seen
several UAVs before, but we haven’t ever seen them weaponized and in action. Yeah, those weapons don’t look lethal, but isn’t that just a matter of ammunition?

It happened at a Marine underwater-acoustics facility, which was pretty nifty, but the real stars of the show were the bots.Cornell’s bot was an impressive beast, fit for underwater research to be certain — it was also freaking huge, in person, compared to most of the other bots. U of Maryland (iirc) had an impressive entry, and they were the last team to compete (being last year’s winners), but according to a member of the team they had a mis-detect of some variety, resulting in an incredibly off trajectory — when the bot corrected, it ran into the wall of the pool and just tried to keep pushing forward. Their mics couldn’t detect the beacon for the final goal (the “briefcase” that they had to recover), so it didn’t know how to course correct. It was sad, just watching it sit in one place.What I found the worst, though, was the “San Diego iBotics” (mostly UCSD students) team’s entry’s story — apparently they were sitting pretty, had a couple good partial test runs, and while they were tweaking settings and testing their system, they had a component failure (fancy compasses apparently !like heat, and they were running it for a long time out of water — aka, uncooled). That went belly-up, and their bot ended up going in circles. It was an impressive entry, anyway — nice carbon-fiber manta-ray design and everything. I was sad I didn’t get to see it compete.Oh well, maybe next year.",

In the last minutes of our 15 minute qualifying run our main programmer managed to diagnose and fix the bug by adding a constant offset but also accidentally commented out a line of code that got us stuck looking downward for the plank to line us up to the next goal after getting under the gate.After a 10 month design cycle from concept to reality we’re happy with how far we’ve gotten and are looking forward to next year.Just a quick shout out to Virginia Tech, you guys were awesome looking forward to seeing you next year!",

As you watch that video, you’ll probably find yourself wondering several things about the
tangible hologram project
. Why haven’t we seen these
simple hologram setups used more often
? Where did that cool air puff system come from and why haven’t we seen more on that? When will this be integrated into the latest Xbox/PS3/Wii? We don’t know the answers to those questions, but we would really love to play with this in person to see how convincing it is.

It isn’t the use of ultrasound that’s impressive here, it what they’re using if for. As far as I know, this is the first time anyone’s used ultrasound to produce artificial tactile response, much less been able to emulate specific surface properties. All the “augmented reality” systems I’ve ever seen required the use of invasive gloves with actuators in them and were extremely limited in their ability to emulate surface textures. This looks pretty impressive and seems like something they might be able to, drastically, increase the resolution of.Personally, I think this would be cool to pair with a pair of VR glasses and, either, an open space to walk around in or one of those omnidirectional treadmills. It wouldn’t be able to stop you from moving through any simulated surfaces, but it would be a large step towards recreating the premise of the Holodeck.",

[Sprite_tm] automated a portion of serial hacking by
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.

“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.
No Starch Press has provided us with
two copies to give away
. Just leave a comment including the words “I want this book.” and you’ll be entered in the random drawing. Please only use the phrase once or you’ll be disqualified. Entries will close
12PM PDT Thursday August 6, 2009
.
Congratulations to our winners [daniel n.] and [Fiach Antaw].

Yo dawg, we heard you liked accelerometers… Apparently people have been wanting this for a while. We’re not completely sure why, so we’ll wait and see what gets done with it. [Ubiq_01] has connected a WiiMote to his iPhone and is using it to control and OpenGL application. He has released a
tutorial
(which seems to be down currently) if you want to try to reproduce it yourself.

Introducing
ERP: Experimental Robotic Platform
. This is an open source, modular robotics platform that, as you can see above, didn’t fair too poorly in the Robogames 2009. [John] has been working on this platform for roughly 2 years and states that it will never be “finished”. It is a development platform, and is always changing and being updated. 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.

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.

"content": "Come on guys, don’t be haters! I was just trying to do some fun, anti-surveillance-related badge hacks.The reason Joe’s face looked normal to you on the video screen is that you’re a way more powerful face recognizer than any computer – and you don’t do it by grabbing and comparing frames. Face recognition works OK in the lab but it’s extremely sensitive to lighting variation – so much so that to use it at ATMs and so on there have been proposals for various kinds of synched strobing illuminators (like low-intensity camera flashes) – see:http://www.machinevisiononline.org/public/articles/articlesdetails.cfm?id=2180If you could synch to the camera shutter as well, you could easily defeat this by strobing yourself and blowing out the image. Some people have suggested constant IR illumination on the face to blow out camera images that are somewhat sensitive in the IR (like many digital cameras, even with IR filters – remember the see-through-clothes function on that Sony camcorder?). But you don’t have access to the surveillance camera synch, and you can’t count on the IR sensitivity of any individual camera. The demo I saw at a conference a few years ago, however, showed that by strobing at close to but not exactly the acquisition rate from multiple light sources you can throw enough noise over the image that the resulting spurious shadows, specularities etc push the recognition rates down significantly, even (and sometimes especially) when the algorithms are using multiple video frames to perform photometric optimizations.I built this at con from scavenged parts so it’s a proof of concept rather than something I’d use to go really robbing ATMs with or anything! I just wanted to make something that raised awareness of the shortcomings of some methods of passive biometric surveillance.Also Wired, bless ‘em, completely neglected to mention the other part of my submission, a fun mechatronic gizmo based on the DC16 badge that was indeed inspired partly by a scene in the movie Sneakers. But it’s also to make people think about this kind of sensing, how it might be defeated and what kinds of tools you could carry to improve the user interface of your chosen method. See this recent real-life heist where pyroelectric IR sensors were defeated with (1) polyester shield; and (2) hair spray and moving a certain way:http://www.wired.com/politics/law/magazine/17-04/ff_diamonds?currentPage=5Anyway, if you think my hacks sucked, I hope it’ll inspire you to blow everyone away with your own hack next year – we know the processor already, so get started early!",

The decision wasn’t only based on technical complexity (which Zoz’s hack didn’t have much of), but also usefulness for the hacker community and just “cool” factor. There are no rules to what portions of the badge need to be used for the hack, but obviously the more of the features I provide are used, the more heavily weighted the entry will be. I’m not going to defend our decision for every single entry (there were 23) As I say every year, if you think you have better hacks for the badge, then come to DEFCON and impress us or just modify your badge and share the results online with the rest of us. -joe",

I could build a totally awesome robot/device at home then come to defcon, break out the leads, program the badge microprocessor and hook it up to my device. That isn’t badge hacking, is it?You should require participants make use of the parts on the badge (i.e. microphone and led) as an active part of their design.

With the availability of webcams and projectors,
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.

Malicious ATM Found At Defcon 17

A fake ATM machine, set to capture ATM information
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.

The ATM was probably about 15 feet away from the security office door in the hall near the buffet. It was actually placed against a column in the middle of the hall. As a casino surveillance professional, I can tell you that the area was not well covered by cameras. In fact there is little coverage in the convention areas. I was tempted to jump up and pull the plug on a still camera that was mounted on the ceiling in a hallway. Both the power and signal cables were just sticking out.",

This
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.

I will try and get some video of it walking up soon.To answer the question in the post – there’s essentially no processing being done in the robot, just a Pololu board which takes serial data commands from the radio link and translates them into servo pulses. All the processing for walking and leg movement is done in the arduino I crammed into one of the nunchuks.This version of the robot I’ve been working on for about two years, on and off, as a fun side project to take along to gaming conventions and such to entertain people with. Building something that can put in severah hours of walking time over the course of a weekend without destroying itself is actually pretty challenging.",

[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
Homemade regenerative tube radio
.

[Jared Bouck] is on a roll this week. We just covered his
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.
