We’ve had a lot of requests in the comments for more Arduino centered posts so we were happy when [Njay] told us about
his EDuino board
. This is a minimal Arduino clone that has a crystal and its capacitors, a pull-up resistor and button on the reset pin, and a detachable serial programming connection. He also has a breadboard-friendly version seen above with all the interface pins on one side of the board. This is certainly a useful project and we’re glad to see the board files available for download. This does get us thinking… is this an Arduino, or is it an
AVR ATmega168 breakoutboard
that happens to use the Arduino boot loader and programming language?

I had to blink my first LED just like everyone else. But at least I was doing it with Industry standard tools and languages that would serve me long-term. Long-term, being adept with Arduino sketches is probably not going to serve you as well as using professional tool-chains and being adept in assembler and the likes of native C/C++.Using the ATMega168/328 with the free AVR-Studio/WinAVR IDE is just as easy (if not easier) than dealing with the likes of the Arduino “IDE”.

We received quite a bit of tips, after posting about the
150$ high altitude balloon project
, from communities and teams who had done similar tasks. There is more to these projects than simply filling a balloon and attaching a camera, so in order to allow everyone their 7 seconds of well deserved fame, we’ve compiled a quick list of similar high altitude balloons. Catch it after the break.
Do note, these are in no order or rank.
RPI Electronics club, sent in their
Imaging Balloon of Science
. Supposedly built in under 30 hours and runs Linux.
Bang Goes the Theory had their own
Space By Balloon
program after being inspired by
Joe Kittinger
.
Brushing up on my Spanish,
Meteotek08
is a dual high altitude balloon that reached a height of 30,000 meters.
Ensure II
is a very impressive setup that actually recorded its flight with video cameras (video above).
NSTAR, or
Nebraska Stratospheric Amateur Radio
, have sent up several high altitude balloons within the past couple of months.
Last, but certainly not least is the
Amateur Radio High Altitude Ballooning
group who have been sending up balloons since 2001!
Thanks to everyone who commented and sent in a tip!

[Chris] liked
Cartesian RepRap
idea so much that he decided to design
his master’s diploma project
around it. Though it uses most of the same parts as
the RepRap
(
even the PCBs
), [Chris] has adapted it
so it does milling
rather
than 3D printing
. Most of the parts (such as the stepper motors)
were harvested from old
inkjet printers and typewriters. The thee-axis CNC machine can already etch and
carve styrofoam at an impressively high resolution
. To deal with all of the debris that comes with milling, a vacuum attachment (shown attached) was created. [Chris] is considering adapting it so it can work with wood and aluminum as well. Best of all, it uses
standard G-code files
, just like the RepRap. A publication by [Chris] on the project is also
available through his website
. No plans to release a kit have been announced yet, but we’ll wait and see. If any commenter knows of an open source CNC milling machine available as a kit, feel free to post a link to it below.

[Andrew Curtis] does fantastic timelapse photography. He found that he wanted to be able to move the camera while taking the shots to give motion to the final product. While this isn’t exactly a new idea, not too many people mess with it. The dolly to do it with can be quite expensive as it has to support the camera and move it in an automated and controlled fashion. [Andrew] has been working on building his own dolly and has
documented the process
.

We thought [Kristofer’s] Tech Tip about
using figlet with scripts
was kind of fun. It’s a throwback to the days of logging onto a BBS and being greeted by a vertically scrolling ASCII art image that had been meticulously hand crafted (although a lot of the
coolest stuff was actually ANSI art
). No hand crafting here, just feed (or
pipe
) your text to figlet and it outputs the message in ASCII style letters.
When we went to try install this in Ubuntu, the toilet package was suggested. This one’s worth checking out too. It works in much the same way as figlet but uses extended characters and has a lot more color and font settings:
Give these packages a try and make character art cool again!

[Dennis] has created a well-documented and very beautiful clock in his
latest project
. This clock stands out from the
other clock projects
we have covered with its unique display. The seven segment LED displays mounted on a sled that moves them back and forth behind an array of fiber optic lenses, effectively taking the display out of focus at certain points. Currently, a
Dorkboard
controls the sled, moving it at random intervals. The case is machined and polished aluminium, the top buttons are ball bearings.

Try using an extra pin to flash an LED at the start of your loop() function. Measure the frequency of that LED and then you’ll know how short of a time period you would have to tap a button for the avr to miss it!Also I was suggesting using the built-in pull-up feature of avr’s I/O pins so that you can just connect the momentary button from the avr to ground. This internally sets a resistor to pull the pin “up” to a high state when the button is not being pressed. If you do it this way, a logical “0” will indicate “button is pressed” and a logical “1” will indicate “button is not pressed”. The benefit is that you only need a SPST momentary button, and no additional components.Hope that’s helpful. Your stuff looks great.…and ditto on inspiring me to finish up that CNC machine…",

Even so, there was a tremendous amount of learning required, from machining processes to learning the CNC side of things (it was a rude awakening when I learned that the computer does very little in generating tool paths – you really need to feed it almost every last detail).",

As cigar aficionados will tell you, cigars should be stored in climate controlled humidors to keep them in best condition for smoking. Most of the time a humidor is just a simple air-tight box with a hygrometer attached, which measures the relative humidity inside the box. Feeling as though he needed more control over the environment he kept his cigars in,
[Justin] created the Tweetidor
, a humidor that
tweets its current temperature and humidity
. Yes, you guessed it; the project is built around an Arduino. It’s a simple, useful project that is well documented and would be fun to recreate if you’re into cigars (and not tired of Twitter or Arduinos yet.) Combine this with the
laser lighter
and you’ve got a pretty nice setup.

Clocks made
from
blinking LEDs
always make for fun projects. [Earthshine] built a
clock that displays time abstractly
using an 8×8 RGB LED matrix. The video embedded after the break illustrates how to read the time but here’s the gist of it: One LED is illuminated in the outside box of LEDs and moved in a clockwise motion to approximate seconds. Inside of this, there are four quadrants; upper left indicates hour-tens digit, upper right hour-ones, lower left minute-tens, and lower right minute-ones. This certainly makes for an interesting conversation piece!
There is no schematic and no code available but it’s really the concept that we’re interested in. If you must know, [Earthshine] bases this build around an Arduino. A DS1307
real time clock
keeps the time, while four 74HC595 shift registers are utilized to control the three LED colors and the multiplexing.

One man’s useless machine is another man’s treasure… or something. [Matt] shared a link to his MP3 gr3nade in the comments of our
useless machines
post. The project took a decomissioned
hand grenade and shoehorned an MP3 player
into it. His decision to locate the headphone jack where the safety pin goes is a nice touch.
This reminds us of the boss from a previous job who had a chrome plated hand grenade on his desk. Now that was a useless object (and a useless boss). This project actually does something, but are you really going to ride around on the subway rockin’ out to
the Bee Gees
while holding a hand grenade?

Hack a Day reader [The_Glu] shared with us a project of his. He used an
Eee PC 701
he had lying around with a broken LCD, along with three 1TB SATA drives to create a custom
NAS
server for his house. The server features a number of other interesting components, including
USB2SATA
converters to connect the hard drives, as well as a
2 line LCD
to display RAID information and server status. The entire project is wrapped up in a custom made Plexiglas enclosure with case fans to keep the whole thing cool. While this may not be the first
Eee PC NAS
, or
the fastest
, this is a wonderful way to repurpose a broken netbook. We also love the idea of netbooks being used more and more in projects like these as the first generation reaches its end of usefulness age. More pictures after the break.
Thanks [

Unless you mean the power went out and you didn’t have battery backup on the controller, or a couple disks failed and you didn’t have enough parity left to recover the array.. that’s not really the controllers fault. Cheap controllers are essentially normal SATA controllers with a extension rom to manage the array setup,.. everything else is done by drivers in software.As long as those bridges don’t corrupt the data (parity covers your arse there too though) and the driver for the bridges can restart them if they hit an error condition he shouldn’t have much of a problem.

Consider that a standard Seagate drive with 5 year warranty is designed with at least one start/stop cycle per day in mind, and laptop drives far more so.The reality is, motor technology has got so good these days that it really isn’t a big issue, unless you keep all your data on just one drive in which case you are doing it wrong anyway.Running the drive 24/7 probably increases the likelihood of failure far more. Heat is the biggest factor in drive lifespan. Google have masses of stats on this. The drive is coolest when it and it’s neighbours are powered down.The power savings are not huge, to be fair. I calculated that a single HDD requires around 50-70p of electricity to run for one solid month, depending on how efficient it is and how much you pay per kwh. That works out at around £8/year/drive.",

[Paul] wrote in to show us this little project he did for his kids. His children love playing with their toy cars. In an effort to give them even more fun while playing, [Paul]
built a stop light
for them. He’s using an ATtiny13 to run them and has the source code available on his site. Not only did the kids get a new toy, he got an excuse to go build something in his workshop.

Nintendo DS Mini USB Plug

Noting that so many of his electronics are using the mini USB plug for charging,
[Xavier] decided to modify his Nintendo DS
to charge via the same adapter. It looks like the existing adapter is basically a proprietary mini USB plug, so replacing it was actually almost a perfectly clean swap job. He has nice pictures of the process and some helpful tips as well. If you’re thinking of consolidating your charging devices, this looks like a step in the right direction.

"content": "I actually bought a third-party charger that had a USB cable and a little “puck” that had a mini-b female jack, and a male jack of the GBASP/DSPhat variety (what I needed), plus a jack of the DSLite variety. It also came with a car adapter for USB. It was all cheap plastic, though, and the puck literally split in two as I pulled the anti-theft packaging open (ugh, hate that plastic). Despite the fact that I was still in the Best Buy parking lot, I was in a bit of a hurry so I went on my way, planning to make a return later. I didn’t, though — when I got home, I took a look at it and saw that the plastic shell that formed the “puck” was completely empty (what I had expected, really) save for the connectors. I took the two I needed (female USB, male DSPhat), soldered on /much/ shorter wires (probably about 1/2″), lined them up and “potted” the whole thing with hot glue. It came out (after a little shaping of the dried glue) as a small adapter of the perfect shape and size for my needs… I paid a little more than I maybe should have for the parts, sure, but a nice little hack. Considering it’s encased in solid hot glue, I don’t suspect it’ll ever break (like the original product did), and I’ve been using it for a solid two years now, I’d say.As for this project, it’s a great little implementation that I could definitely see doing myself — eliminates another adapter, which is always nice.",

Couple problems, though — some devices use more than 500mA to charge on their 5V adapters… more importantly, though — the peripheral makers would complain, and Nintendo wouldn’t be able to charge $waytoomuch for their own adapter. I do think that those companies who /do/ choose to utilize 5V USB for their charging, and other such standardized plugs, should definitely be applauded for their decisions, though, and I personally use this as a deciding factor when comparing two otherwise similar products.",

I had a dead mouse that I saved for parts. Cut the USB cable off and wired the cables accordingly. The DS charges just fine at 5v 500mAh, since the power brick does 5.2v at 450mAh. The general rule is within 5% (and some cases, within 10%) voltage (over/under) if it’s not matched, unless the electronics are especially sensitive… and to provide more amperage than it draws. 5v is 96% of 5.2v. USB wall warts automatically push out 500mAh, I have two that will provide up to 1.2A right out of the socket. More than safe enough.Put me in the group where Mini or Micro USB should be on EVERY electronics device. Tired of proprietary plugs and wall warts. I wish I had the unit or even took pictures, but I did a similar hack to a portable CD player after the circular jack broke. This was back in 2000ish and it was a good enough model of portable CD player that it was worth saving. (80 hour battery life on 2 AA’s with an external battery pack plug on top of that. It ran for forever on a single pair.)",

cool little email notification device he made
. Using a paper model of Wall-E, he added some servos and connected it to his computer using a PIC. Mail-E has independent arm rotation and head rotation. He admits that the PIC processor is major overkill and plans some upgrades such as making it wireless and using a little better suited chip to control it. Not bad for a proof of concept.

Pulse Width Modulation is a topic that tends to give a lot of beginners trouble. [Daqq],
whose nixie plasma ball we covered
a few days ago, has a simple but effective PWM project that you should take a look at. The circuit used 9 LEDs clustered together into 3 sets of RGB modules and connected them to an AVR ATtiny2313 through some current limiting resistors. Most of the time the PWM function of the AVR’s timers would be used to generate the signal but this application calls for 9 signals which is more than can be produced by this chip. The workaround is to generate the signals using software PWM.
Make sure you
read up on PWM
. Once you’ve got a good idea of what you’re trying to do, check out the code that [Daqq] included with his
YALBlinkie project
. When studying main.c from the project package, notice that a timer is running that periodically adjusts the duty cycle of each signal. Meanwhile the infinite loop within main constantly scans the output pins with the duty cycle values the timer is setting. This results in the amount of time the LEDs are illuminated being slowly changed, making them fade in and out.
Because ATtiny2313’s are very inexpensive, this is a great way to jump into using the AVR line of microprocessors. You will need a programmer but there are ways of
using an Arduino to program these chips
. To learn more about timer interrupts and how these chips work, check out the
tutorial section over at AVR freaks
. Also take a look at the avr-libc documentation for an explanation of how to
fix the deprecated sbi and cbi commands
in [Daqq’s] code.

A lot of people like
fancy GUIs
and
nice graphics
, but some of us just feel more at home in a command prompt. [nevdull] is one of those people. Instead of just using the Arduino dev tools that are available for download, he wanted the ability to shell into his Arduino, so
he created AVR Shell
. AVR Shell is a UNIX-like shell that allows you to “log in” to your Arduino/AVR and see what’s really going on; letting you read registers, scale the CPU speed, create/edit/delete variables, and even set up timers. The shell is even user-customizable! Those of you interested in Arduino shells might also
check out bitlash
, another open source CLI. Someone ought to hook this up to the
Internet enabled Furby
and get
Flite
compiled on there, letting us shell into a Furby from miles away to make it talk.

What can you build with a ballpoint pen and some extra parts? [gzip] found himself with a bonus box of right angle switches and other miscellaneous parts and set out to
build a joystick
. Simple
arcade joysticks use switches
that are actuated by the movement of the stick and this design embraces the concept. The four tactile switches are mounted on protoboard facing each other with part of a ballpoint pen in the middle. When the pen is moved it presses against one or more switches to close, completing a circuit. For good measure he even incorporated a fire button into the top of the “stick”. Now we just need someone to make this work with a
tiny Ms. Pac-Man
emulator.

[Tim] wanted to make some recordings of himself driving similar to those made by the dashboard cameras on police cars. In a simple two step hack (1. Measure, 2. Drill), he
altered his iPhone windshield mount so that it didn’t block the lens of the camera
. We will admit (sheepishly) that at first glance we thought this might be connected to the outside of the windshield but it’s not. Take a look at his drive to work after the break.

The guys over at
Xmarks
are working hard to bring their bookmark synchronization service to all browsers and platforms. They’ve recently begun a closed alpha test for their Google
Chrome
/
Chromium
extension. We got an invite and decided to give it a test run. Since
extensions
aren’t yet fully supported, and still a bit buggy you’ll need to use the latest build in the dev channel of Chrome, which means at least version 3.0.196.0 or newer. We tested it on version 4.0.207.0 for Ubuntu with great success. The extension is still pretty basic since it’s still at an alpha stage, but works very well with synchronizing bookmarks across different platforms and browsers. Some of the things left out from the Firefox version are profiles, smarter search, site info and suggested tags. For an alpha release, it’s very well done and functions great, and we’re certainly looking forward to this extension as it develops further.

Are You Human? Then Type Out This Book

Google has acquired reCAPTCHA
and plans to use the system for digitizing books. Wait… what?
CAPTCHA
is the method of requiring a user to type in a visually obscured word to prove they are human. How can this digitize books? The answer is a bit obscure and takes some time to discover, but you’ll have fun along the way.
The Google blog links to a Google TechTalk video on Human Computation as an example of how they plan to use their new acquisition. It’s embedded below but at 51 minutes we figure most won’t watch it all so we did it for you. This fascinating discussion looks at how people are already being tricked into solving CAPTCHA challenges, and shows several tested implementations of getting people to input cognitive data computers cannot, under the guise of playing games.
Spammers have to beat the CAPTCHA system in order to get large numbers of free email accounts. There have been examples of software overcoming this test such as the
greasemonkey script that beat MegaUpload’s security
, or
Time Magazine’s poll being hacked
. But, for the most part, only humans can pass the test. People seeking to bypass millions of CAPTCHA challenges either pay for sweatshop laborers to solve them or, more creatively, they get you to solve them when cruising for porn. This is the proof of concept; we
can
use people to interpret words computers cannot if we use the right carrot.
Talked about in the video,
the ESP game
was written in order to correctly tag photographs. Players are shown pictures and asked to type what they see. The round keeps going until the two have typed the same word. With a lot of players, and proper safeguards, these tags are incredibly accurate. Furthermore, the game has been very popular and has the potential to accomplish herculean feats in short amounts of time (namely, tag every image in Google’s image search in just a few months).
It seems that Google plans to use these methods to digitize books that are otherwise very difficult to scan with
Optical Character Recognition
. According to the video, 9 billion human hours were spent playing solitaire in 2003. What if a small portion of this time could be diverted over to playing games that added to the digitized knowledge cache? If the right type of verification game can be developed it will allow Google to tap society as their typing minions. It’s an interesting proposition and frankly we hope to see it happen.

True captchas should base their decision on things that only humans understand. KittenAuth is on the right track, but still asks to determine which is a kitten…the possibility is that image recognition will eventually be able to identify kittens. So we have to take it into the human-only domain. Show pictures and ask “Which animal is cutest?” “Which animal is scariest?” “Which face appears untrustworthy?”. Maybe show short passages of text and ask “Does this make you feel happy, sad, scared” etc. You would need a large pool of sample material that may eventually be manually identified, but there is no shortage of new images. I think we have a ways to go before computers understand emotions, and by that time they may refuse to spam us :)",

It is an issue my family and I struggle with. Despite all of the safe guards on our data and the numerous copies, I would say the oldest digital file we have is from the late ’90s.I am 33 and I have 33 year old pictures, ~23 year old CDSs and 31 year old drawings. I have been using a computer for 25 years, but I think my oldest file is from 1997. Will I have 23 year old CDs? Digital Photos? I am not sure.It may make an interesting post to see the best way to preserve data and also to find the oldest files that people have that is still readable (I dont think a 12 inch floppy counts).

And YES, THERE IS A MUCH GREATER VALUE FOR EVERYONE! Whether or not you want to read a Markist publication or you want to read something from the Wall Street Journal 45 years ago. This is still a boon for the human race as a whole. And someday, and I hope it is not soon, your eyes may need help in reading something. And I know, and I hope it happens very soon, a computer will either be able to magnify or even read the text that you wish to read to you. Think about the long run when you anti this or anti that before you say die capitialist pig die.On the technical aspect of this, you must tip your hat to Google for thinking about this. Google had to take some of their evil capitlisticly gained money and buy a helpless small business (capitalistic company) and when they could have used it for simple passphrases, they decided to translate old texts much cheaper and probably much more accurately than any team of humans on the same book would require and probably do wrong, without having to worry about interpretation.As far as Capitalist Pig Company Google is concerned, I could think of much worse things than this they could be doing and are not. And while I am not exactly a fan of Capitalist Pig Microsoft either, I can tell you that computers have done a lot more to enrich our lives than they have done to harm us. One being this forum, which I hate going political on, it is a site for innovation, not for political discussion.The known word and unknown word is slick. Yes someone is going to go “flag” on the word “marine”, but you are not going to get fifty different IP address polls to agree to that, even if you spoof. It won’t be two or three people agreeing, it will be thousand, or greater. Even with spoofing it is not worth the effort to do. And if there is a fifty/fifty concensus poll on a word, then you can send in a few humans to look at the word without Captcha.

[Costis] managed to dump a copy of the boot ROM for the
Nintendo Super Game Boy
. This small piece of code (256 bytes) writes a graphic to the display at boot time as it loads the ROM on the game cartridge. He was able to dump the code by finding the exact point at which the device locks down the boot ROM. Just as that point approached he overclocked the device causing it operate so fast it couldn’t write the lockout bits into the register. Once past that single point of security, he executes a code that writes the boot rom out to a different address that he is able to read from. He’s got a
copy of the dump along with the explanation
up for your enjoyment.
[Thanks Anthony]

Since the adoption of Kernel 2.6, Linux has used the
udev system
to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded. The operating system we used for this exercise is Ubuntu 9.04 Jaunty Jackalope.
Background Investigation
Before writing rules, we have to gather all the information needed to identify our device. We found the
block device node
that the drive was assigned to by plugging it in and checking
/var/log/messages
. We then pass that location (/dev/sdd1) to two commands that we run at the same time. Some distributions use the “udevinfo” command but with Ubuntu 9.04 the command has changed to “udevadm info”:
udevadm info -a -p $(udevadm info -q path -n /dev/sdd1)
The output of this is pretty meaty. We need to find the top of the chain that provides the block node which is used for mounting removable storage (in our case, /dev/sdd1). Using this KERNEL as identification will ensure that our symlink points to a mountable block device and not some part of the USB controller. We are also looking for device specific identifiers that differentiate this particular thumbdrive from all others:
looking at device '/devices/pci0000:00/0000:00:02.1/usb1/1-2/1-2:1.0/host29/target29:0:0/29:0:0:0/block/sdd/sdd1':
KERNEL=="sdd1"
SUBSYSTEM=="block"
DRIVER==""
ATTR{partition}=="1"
ATTR{start}=="63"
ATTR{size}=="31310622"
ATTR{stat}==" 208 15448 16282 776 2 0 2 12 0 508 788"
looking at parent device '/devices/pci0000:00/0000:00:02.1/usb1/1-2':
KERNELS=="1-2"
SUBSYSTEMS=="usb"
DRIVERS=="usb"
ATTRS{configuration}==""
ATTRS{bNumInterfaces}==" 1"
ATTRS{bConfigurationValue}=="1"
ATTRS{bmAttributes}=="80"
ATTRS{bMaxPower}=="200mA"
ATTRS{urbnum}=="1858"
ATTRS{idVendor}=="13fe"
ATTRS{idProduct}=="1f00"
ATTRS{bcdDevice}=="0110"
ATTRS{bDeviceClass}=="00"
ATTRS{bDeviceSubClass}=="00"
ATTRS{bDeviceProtocol}=="00"
ATTRS{bNumConfigurations}=="1"
ATTRS{bMaxPacketSize0}=="64"
ATTRS{speed}=="480"
ATTRS{busnum}=="1"
ATTRS{devnum}=="69"
ATTRS{version}==" 2.00"
ATTRS{maxchild}=="0"
ATTRS{quirks}=="0x0"
ATTRS{authorized}=="1"
ATTRS{manufacturer}=="OCZ"
ATTRS{product}=="DIESEL"
ATTRS{serial}=="50E6920B000AE8"
In writing a udev rule, any of these characteristics can be used as conditions for the rule’s execution. That being said, only properties from
one
parent of the device and from the device itself can be match. Trying to match values from more than one parent in the chain will be invalid and will not work.
The Rule
Rule files are stored in the
/etc/udev/rules.d/
directory. We got some advice from the README in that directory on how to name rule files:
Files should be named xx-descriptive-name.rules, the xx should be
chosen first according to the following sequence points:
< 60 most user rules; if you want to prevent an assignment being
overriden by default rules, use the := operator.
these cannot access persistent information such as that from
vol_id
< 70 rules that run helpers such as vol_id to populate the udev db
< 90 rules that run other programs (often using information in the
udev db)
>=90 rules that should run last
We plan to run a script with this rule so we gave it a name that started with a higher number than our other rules but lower than 90. We used the filename:
81-thumbdrive.rules
The first part of a udev rule is the matching keys. We will use the KERNEL entry from the very top of the chain as well as the idVendor, idProduct, and serial attributes from the device specific information. This will positively identify this particular thumb drive and ignore all others. The kernel argument uses a question mark as a wild card so that if our drive were mounted on a different node (ie: sda1, sdb1, sdc1, etc.) it could still be identified.
KERNEL=="sd?1", ATTRS{idVendor}=="13fe", ATTRS{idProduct}=="1f00", ATTRS{serial}=="50E6920B000AE8"
Now that we have the keys necessary to identify the particular hardware we’re looking for we can add assignment arguments. In our case we added two. The first creates a symlink to this device inside of the /dev/ directory. The second executes a script in our home directory:
SYMLINK+="hackaday", RUN+="/home/mike/notify-plugin.sh 'HackaDay Thumbdrive:' 'Connected as: $KERNEL'"
Here is the final rule assembled into one line:
KERNEL=="sd?1", ATTRS{idVendor}=="13fe", ATTRS{idProduct}=="1f00", ATTRS{serial}=="50E6920B000AE8", SYMLINK+="hackaday", RUN+="/home/mike/notify-plugin.sh 'HackaDay Thumbdrive:' 'Connected as: $KERNEL'"
We added this as the only line in our rule file and then restarted udev using these commands:
sudo nano /etc/udev/rules.d/81-thumbdrive.rules
sudo /etc/init.d/udev restart
The Script (and the bug workaround)
We wanted to use the
pop-up notification we covered a while back
but couldn’t get it to work. After a bit of frustration we found out that
the notify-send package has trouble
putting notifications on a user’s screen when called from a script run by root. There is a
workaround for this bug
. We altered the script just a bit for our purposes and pasted it to a new file named: /usr/local/bin/alt-notify-send
#!/bin/sh
user=`whoami`
pids=`pgrep -u $user gnome-panel`
title=$1
text=$2
timeout=$3
icon=$4
if [ -z "$title" ]; then
echo You need to give me a title >&2
exit 1
fi
if [ -z "$text" ]; then
text=$title
fi
if [ -z "$timeout" ]; then
timeout=60000
fi
for pid in $pids; do
# find DBUS session bus for this session
DBUS_SESSION_BUS_ADDRESS=`grep -z DBUS_SESSION_BUS_ADDRESS \
/proc/$pid/environ | sed -e 's/DBUS_SESSION_BUS_ADDRESS=//'`
# use it
#icon hack:
if [ -z $icon ]; then
DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS \
notify-send -u low -t $timeout "$title" "$text"
else
DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS \
notify-send -u low -t $timeout -i "$icon" "$title" "$text"
fi
done
We then created the script that the udev rule calls. This is placed in our home directory at /home/mike/notify-plugin.sh
#!/bin/bash
su mike alt-notify-send "$1" "$2" 6000 "/home/mike/hackaday_icon.png"
The script can do just about anything we want it to. In this case it calls the notification workaround script passing two strings from the udev rule, a delay time, and an icon to display with the pop-up.
Order of events:
Now that everything’s in place, let’s take a look at what happens when our drive is plugged in.
-USB drive is plugged into the computer
-Udev checks the /etc/udev/rules.d/ directory and starts using the rule files in order
-Udev gets to our file: 81-thumbdrive.rules and matches the “sd?1” kernel, idVendor, idProduct, and serial number of the thumbdrive.
-If udev confirms a match on our four conditions, a symlink is created at /dev/hackaday and the /home/mike/notify-plugin.sh script is executed, passing it a message that includes the kernel information.
-Our script executes creating a pop-up notification using the alt-notify-send workaround.
-HAL takes over, automatically mounting our drive (this is part of Ubuntu’s removable storage handling and unrelated to our udev rule).
Here we see the symlink pointing to our block device and the pop-up notification:
Other uses:
Udev rules give you control over the hardware attached to your machine. If you are working on a USB connected project, these rules will allow you to set permissions for access, execute scripts when added or removed, and provide a persistent symlink for accessing this hardware without relying on the same node name each time the device is connected. We use a udev rule to allow
avrdude
to access our
AVR Dragon
programmer without root permission. In this case our rule sets read/write permissions for owner and group, then assigns the device to the “plugdev” group. As long as the user trying to run avrdude is a member of the plugdev group the program will be able to access the dragon. Here’s the rule:
SUBSYSTEM=="usb", ATTR{idVendor}=="03eb", ATTR{idProduct}=="2107", MODE="0660", GROUP="plugdev"
We hope this helps clarify how the udev system works. Give it a try with your next project.

Touch Sensitive Keypad

[Viacheslav] built a
keypad that uses human capacitance
to detect key presses. Unlike normal keys which close a physical connection, his project detects touch through the PCB substrate. He uses the analog comparator of an AVR ATmega8 to detect the moment of
zero crossing
and then measures the time it takes to discharge in order to detect key presses.
I use analog comparator to detect the moment of zero crossing and the charge is evaluated by measuring time. Builtin AVR ADC probably wouldn’t be very useful here because the charge that can be built up is very small.
Update:
[Viacheslav] left a comment to let us know we had it wrong. Instead of using the ADC, the analog comparitor is used. This change has been made above.

Tech Leaders Enlisted To Help The Newspaper Industry

"social network"

It is pretty obvious to everyone that the newspaper industry is in a tiny bit of trouble. They have thus far failed to reach the rapidly changing landscape of news, online news at that. They must do something to keep our interests up, or end up flailing on the ground. Microsoft and Google among others have recently entered the picture with solutions to the problem and some fresh eyes from a digital perspective.
Leading edge tech companies enterend the picture with a plea from the
Newspaper Association of America
on how they can monetize content online through transactions or enhanced ad targeting. Microsoft submitted a news river system that resembles TweetDeck and Sobees. Google is looking at developing an extension of Google Checkout that would help newspapers charge for content through a micropayment system. IBM as well as Oracle have submitted proposals that look at the use of content management systems.
So far the only shining example of the possibilities newspapers have to push things forward is Microsoft’s Next Generation Newspaper that pulls in all sorts of data such as RSS feeds, photos, videos, updates and news from across multiple news as well as social networks, into an information hub. So what does all of this mean for you? Newspapers might not be dead, they are in the hot seat and looking at the best of the best to help them out of the jam with intuitive solutions that meet today’s news viewing needs.
What would you like to see newspapers do to engage you as an online news viewer?

"content": "What the newspaper companies need to do is this;Make E-paper tablets, setup some sort of update point in local newsagents, then sell these E-paper tablets at cost (keep it under £10 if possible). Then when anyone wants a newspaper, they just goto the local paper shop, supermarket etc and update the E-paper with the new issue for a small fee.Maybe even make the E-paper micro sd card run? Then they just have to keep a small keychain attachment for storing their micro sd card, that way they can also save copies of old papers on their pc/laptop etc and plug the sd card into the E-paper tablet to re-read anytime they want.The newspaper comapnies will save millions since they no longer have to print all the papers, no longer have to distribute them nor collect the un-sold ones and recycle them.All that will be necessary is a reliable distribution server, connecting all these stores to anyone’s E-paper to update to the new newpaper!Once all the newspaper companies come onboard, the running costs will be substancially lower since they all contribute towards the running of the main distribution server, but customers have an option of which paper to buy at the store.",

Paper is just another means of getting news in your face, just like the e-tablets are. Breaking news and multi media along with outstanding journalism will save this industry.Though revenue from print advertising is still tremendously larger then that from web advertising. We all know that charging for content will lead to loss of visitors, thus less value for advertising. So I predict that will never happen. What I see happening is more intrusive ads based on behavioral targeted advertising with free access to content.Classifieds are another story though. With craigslist taking over it is going to be harder and harder to sell classified ads. Though with increased inovations of displaying classifieds this could change.All in all this industry is evolving rapidly and is an awesome thing to be a part of.",

As a fellow countryman I witnessed his “race for the bottom” (no page 3 pun intended) in Australia long before he went forth to take over the world.His newspaper group contains the very worst of the sensationalist bottom feeders. His tabloid in my city is the Herald-Sun aka “The Hun” for its shock-jock luna-Right (and anti-Interweb) editoral policies and columnists. For example, while the smoke was still clearing from our bushfire disaster that killed 200 people last summer one Hun columnist seriously called for the public lynching of “Greenies”.A few papers here tried an on-line “first item for free, then you have to register (for free)” model and readers stayed away in droves – they wouldn’t even log in, much less pay. Lasted less than a year.I still buy a physical newspaper most days because I find on-line content lacking in depth (and I can’t read it in bed).The recording industry is flogging a dead business model and now Murdoch has joined them. Hell will freeze over before Murdoch gets one microcent out of me towards his next billion.@JoelSimilarly the so-called “music” industry has in reality been selling plastic media and is clueless now the music has decoupled from plastic.Newspapers do not exist to bring readers the news.

Make the esheet reusable/chargeable and it’d get quick adoption due to its novelty gadget value. Tie it to a subscription fee of 50p/50c, and boom, they’ve got thousands more regular customers than they’ve ever had, and once you’ve got them reading and liking the news, they’re not going to stop just to save a few pennies… Plenty of revenue, and people don’t mind paying because it comes in a physical form.Add in some smart software to make the paper more relevant to the consumer (RSS reader style), and all of a sudden you’ve got a cheap to make-and-sell product which draws in more than enough income to cover the journalism costs, and the print/distribution costs are next-to-zero (obviously not really, but much, much cheaper than current paper-printing and shipping). It’s just a game of waiting for the tech to become cheap enough, and then a competition for who can make the best soft-interface (and the best content, it ought to go without saying…).",

[Oleg] over at Circuits@Home has made a
USB isolator
for his hacking needs. This isolator separates the signal, ground, and power lines of a USB host device, such as a PC, from a USB device like a USB oscilloscope or
logic analyzer
. This might be useful for
Keyboard sniffing
,
ECG
,
EEG
or diagnosing the control system on the positive ground of your autonomous
Ford 8N
. What other applications can you come up with for this tool?

in 1983, [Steve Roberts] packed up a Tandy 100 laptop and a 5-watt solar panel, fleeing suburbia on his
recumbent
bicycle
on what would become a 17,000 mile journey that forever cemented his place in the geek pantheon…not just as a technology hacker, but as one of the preeminent “life hackers,” pursuing his own dreams on his own terms and inspiring others to do the same.
In this 1989 video, recently unearthed by Hack a Day, [Roberts] reflects on the first 16,000 miles of his voyage, detailing some of the technology that went into his then-current ride, the
Winnebiko II.
[youtube=http://www.youtube.com/watch?v=tDaz8vaKzdQ&color1=0xb1b1b1&color2=0xcfcfcf&hl=en&feature=player_embedded&fs=1]
Next time you’re comfortably working from the local park with your laptop tethered to a 3G connection, raise your latte in toast to [Roberts], who was
pioneering the “mobile professional lifestyle”
more than
two decades ago.
There was no Google Maps, no mainstream consumer internet, no 3G wireless. It was all packet radio and acoustic couplers on pay phones. Where he casually speaks of “living in the computer networks,” he’s referring to CompuServe, GEnie and UUCPNET. And next time you’re trapped at a green light while the driver ahead of you is distracted by text messaging, you can
curse
thank [Steve] for that, too…with his handgrip-integrated keyboard, he may well have invented texting while driving.
[youtube=http://www.youtube.com/watch?v=us19S7cNAVU&color1=0xb1b1b1&color2=0xcfcfcf&hl=en&feature=player_embedded&fs=1]
[Roberts] is still blazing trails…tinkering, writing, and living the “technomad” lifestyle, now by sea instead of land. You can follow along with his adventures on two web sites:
microship.com
is now primarily a retrospective of the past quarter century…the
Winnebiko/BEHEMOTH
bike projects and subsequent
Microship
trimaran, along with archives of his writings.
nomadness.com
looks ahead to “open-ended global voyaging” on his new vessel, the
Nomadness.
The site contains articles and reviews, photos, and his
blog
with current status updates. There’s also the Nomadic Research Labs
Store
, where you’ll find [Roberts’] own books, project surplus, and boating and electronic parts.

[Jair2k4] learned the hard way not to lend out your expensive GPS to untrustworthy people. His
Garmin 200
was returned with a broken USB port and unable to charge. Luckily, all it took was some inventive thinking and he had it repaired in no time. By breaking open a Nokia cellphone car charger, he had a source of 5 volts. After that, it was only a matter of soldering the connections. However, not content with the design he pulled out a Dremel and mounted it in his 1991 Suzuki Sidekick. Quick, dirty, and actually working afterwords, just the way we like it.

How To Replace A Netgear Router Antenna

a.ntivir.us wanted to use a
different antenna for their Netgear mbr624gu WiFi router
. Unfortunately, this model comes with an antenna that is not removable. As with
other antenna retrofits
, this involves no soldering. But because there is already a mounting area for an antenna, no case altering is needed either. After opening the router with a Torx driver it was discovered that the non-removable antenna was connected to the board with a
mini rf connector (U.FL)
. The antenna and its mounting bracket were removed and a U.FL to RP-SMA adapter was put in its place using a washer to secure it to the rear plate of the router. Now
any external antenna
can be used and the router still looks brand new.

The majority of us doing the complaining have been doing all of the ‘real work’ as you put it since before most of you were around to read this site, as pitiful as it has become. some of those people are responsible for the hacks and tweaks that made all of the crap you carry in your pocket today possible, and we’re a little pissed that instead of advancing technology, we’re feeding the drooling masses stashes of retardcandy.Those of us who have been here since the beginning can see how fast it’s turning to shit. There’s no real hacking going on here anymore, only regurgitated horseshit that serves no useful purpose.You sit there and talk a storm of shit about us when you obviously have no clue why this site was created or what it’s supposed to be about. the fact that it’s turning sour is really saddening to some of us.I mean replacing an antenna with one that screws loose from the connector… wow groundshattering. And when you talk about the Matchbox nonsense, let’s not forget the multiple waste of space posts regarding Lego ‘hacks’.Building shit with Legos is not a hack, it’s something children have been doing since the inception of Legos. Unless you build me a hybrid car or something out of Legos, then I’m ready to read. The damn Legos in the post probably cost more than an actual stand so what’s the point? Exactly… there isn’t one, except to bloat up the posts.But hey, glad the retardcandy is working for the rest of you, at least if you’re busy reading and posting here, you can’t be out causing real trouble in the world.",

Sure, in times of draught the hacks were a bit less technically impressive, but on average there was a good quality of hacks posted on the site every day. Nowadays, I get the impression that at HAD-HQ the general idea is that if something is found that looks like a hack, they’ll post it. I personally wouldn’t mind the bar being a bit higher, with perhaps one-hack-a-day-periods if there isn’t that much interesting in the tip line rather than filler posts about legos or matchbox-cars.On the other hand: usually the technical level of a hack is immediately visible.

Don’t feel like shelling out $5 for a fancy factory made calculator that won’t even do binary math? [Jeff] decided to prove his mastery of gates and his disdain for base 10 by building a
binary calculator using XOR, AND, and OR chips
. Calculations can be input in two ways: through digital logic headers or by three banks of DIP switches used to enter the operator and the two operands. Although limited to addition and subtraction, this is a great way to make sure you really understand digital logic. Take a look at the rough design schematics in
his album
. The design is modular so if you have one of each gate and a few LEDs sitting around you can give this a whirl.

For a divider you’re stuck with an even bigger chunk of gates.My project last semester was a 32-bit 2’s complement kogge-stone [4×4]*[4×4] matrix multiplier. A single multiply unit (IIRC) took somewhere in the neighborhood of 15k gates.If circuits such as these intrigue you, Atanua (http://sol.gfxile.net/atanua/index.html)is a much simpler way to test things out without the rat’s nest of a proto board or the pain and agony of wire wrapping.

The Blind Juggler

[vimeo = http://vimeo.com/1621390]
The
Blind Juggler is a robot that juggles
or bounces balls in a controlled manner without any sensory input. It is basically just a linear actuator with a paddle on the end to smack the ball back into the air as it returns to the ground. The crazy thing is, it is doing this based purely on pre programmed math. There are no sensors telling it to make any adjustments. While we could envision this functioning, we would never have expected it to be as stable as it is. You can see in the video above that they can actually move the entire robot around while maintaining the bounce. Also check out the pendulum version, instead of just actuating vertically, it is mounted as a pendulum allowing the ball to travel back and forth in an arc.

"content": "Aha, so it accomplishes this seemingly impossible task by using a concave paddle that forces the ball to remain centered, and plain old physics calculations to ensure that (ideally) the paddle is decelerating when it hits the ball. A ball that bounced too low last time will hit the paddle when it is still moving faster. A ball that bounced too high last time will hit the paddle when it is moving slower.Very clever indeed. It needs an Arduino, though.",

[Kyle] decided to build
the above LED clock
for his church. Though it may look impressive enough, it is also
hiding loads of features
. [Kyle] wanted to make the clock as easy to control as possible, so rather than use buttons or dials to control what is being displayed, he used Twitter. The clock is connected to the internet through a
Linksys WRT54GL
. The router
was hacked so
not only does it supply the connection to Twitter, it also parses all of the replies
the clock’s feed
gets. The clock responds to commands to turn it on or off, run a countdown before service, display the number of viewers on the church’s live stream, and display a sequence of numbers. The time never needs to be set, as it is
synched from the internet
. The
circuit for actually driving the display
is based off a PIC, but it was changed to run off an Arduino.

See this page for more details:http://en.wikipedia.org/wiki/Anthropic_principle“Then, magically, a planet was formed at the perfect distance from the correct-sized and aged sun, surrounded by a moon that was just right to stabilize the spin of that planet and induce tides.”Not magically, but scientifically. There are clearly defined laws and guidelines which define how and when planets can form. Also, as far as the earth, moon, and sun being correctly positions, please refer to the page on the anthropic principle.“Then, molecules randomly assembled themselves to form living structures that scientists, after a 100 years of study, still cannot reproduce.”This is absurd. What molecules can’t scientists reproduce? Name one.“Lets not forget that these primitive structures then developed, on the basis of natural selection and mutation, into beings capable of pondering god and their own creation (a talent, by the way, that has no “evolutionary” benefit, and should not have developed via “evolution.””Not everything has to have an “evolutionary” benefit. Evolved traits only come into play in a critical way when they they determine the lifespan/number of offspring or the creature in question. Maybe the ability to ponder “god” is actually an evolutionary DETRIMENT, since when too many humans ponder “god” differently they end up mass-murdering each other over conflicting beliefs.“The *data* shows evidence of refined design.”Prove it.“You are correct that there are *large* numbers of otherwise rational people who are buying into utter bullshit, but it’s not the people you think.”Die in a fire.“As an engineer, I can recognize the difference between random events and design.”If, as an engineer, you believe in “intelligent design” (creationism), that’s your decision.

[Fritz] built this
600 joule
capacitive discharge spot welder in a case scavenged from a Lincoln plasma cutter. All of the circuitry was designed by [Fritz] and the schematics are available
on his website
. He has a few other welding related project also documented on his site that are worth checking out. While this isn’t the first
homemade spot welder
we have seen, it is definitely the first one with a case mod. If you are not up to the challenge of building one quite as complex as [Fritz]’s example, a
microwave can be used
as the donor appliance in simpler designs.

Zune HD Teardown

Our friends over at ifixit are at it again, how they get these devices so early before release and make a complete teardown in time still amazes us. Today they bring us the latest Microsoft media device, the
Zune HD
. Some features worth mentioning: The astoundingly thin, 1mm we’re talking, OLED screen. The Nvidia Tegra 2600 processor,
hinting at 3D game capability
. And finally who could forget the 660 mAh battery. But isn’t that 129 mAh less than the
iPod touch
? Microsoft’s reply, supposedly the Zune HD is using many more low power hardware solutions in this device. Either way, the competition is on, who will be the victor?

SecurityTube – A YouTube For Hacks

[

"hacking",
"securitytube",

"youtube"
] |
SecurityTube
is a site which has recently caught our attention. The site has quite a variety of videos from various sources related to security and hacking. Videos range from
DEFCON
talks, to documentaries, step by step how tos, and even proof of concept vulnerability videos. It’s certainly a great resource for anyone looking for something a bit more involved then a plain text writeup, and offers a way for you to catch those hacker conference talks you missed. Many of the videos come with a bit of a background information as well, so it’s far more informative then your regular YouTube videos. This site is certainly going to become a very valuable resource for many people, and is certainly a great way to kill an afternoon while still learning something.

PhoneTag Helps You Read Your Voicemail
|
Chris Gilmer
|
[
"Cellphone Hacks"
] |
[
"phone",
"speech to text",
"voicemail"
] |
Have you ever been too busy to check in with your voicemail service?
PhoneTag
might have the solution for you.
Some of us might have done it before, let voicemails pile up if we know nothing urgent or important is coming down the pipes. Wouldn’t it be much simpler and more convenient if those voicemails played by our rules? PhoneTag is a speech to text service that converts a voicemail into text and sends it via email or SMS which you can read through and reference at will. The accuracy on this type of service is usually pretty good, but some translation is required as spoken words can sometimes be misinterpreted depending on the clarity of the call. On the security side of things, we tend to be a little hesitant of personal and business voicemails running through an extra service. PhoneTag does state that they use some kind of “special algorithm” that will guarantee voicemails are secure and private.
While there is a free trial period, this service is going to cost you. You can sign up for anything from a per message price of $.35 to an unlimited plan of $29.95/month. You are going to have to do your own calculations here to see if this is the best way to go, but this will save you from using your monthly minutes for checking the voicemails in your mailbox. As alternatives,
Google Voice
offers the same service for free and
SpinVox
charges a fee per use.

I get a lot of compliments on that alone.I’m waiting on my Google Voice invite, but I don’t know if I like the idea of changing my phone number. It’s printed in a lot of places and I’m not sure how a forward would work out with cell provider charges.I think I actually like the idea of some kind of hybrid of Google Voice for handling live calls, but still sending voicemail to YouMail… unless Google can add the custom greetings. Then maybe it would be a total solution.I won’t know until I have an invite though… anyone have one they’d care to give me? Or is it all still in-house handled by Google?",

Nixie Plasma Ball

This one came out over a year ago and we missed it. [Daqq] has
made a plasma ball out of a nixie tube
. All that was required was the transformer from a cold cathode meant for computers and a nixie tube. He did have to do a tiny bit of modification to the power supply, which you can see on the project page. This isn’t the most useful project, since you can’t really see much of the plasma, but it is really cool nonetheless. We think this would make a really neat button. You can see a video of it in action after the break.

In storage they seem to have almost infinite life with tubes manufactured several decades ago still working perfectly when applied.Since standard light globes are filled with low pressure argon these might also be worth giving a go if you want a more bluish discharge.@googfanGo for it!",

We’ve
covered
sequencers
before
, but reader [Johan] sent in his latest project that is much more minimalistic approach. Dubbed
the BBox
, he based his drum generator on an Arduino and an LCD display. Rather than synthesizing sound, the Arduino just outputs MIDI which is then interpreted by his Roland Juno-D. In building the device he used a
favorite trick of ours
to keep the interface clean. He then found an awesome banana box to use as a case. Although, the project may not be as functional as some of the others out there, it certainly has flair. Video of it in action after the break.

[Melanie] had some time this weekend so
she whipped up a dual voltage power supply
from parts on hand. This design plugs right into a breadboard and, unlike
the last breadboard power supply we saw
, provides two voltages at one time. 5v is delivered to one power bus while 3.3v goes to the other. Her design uses two linear low voltage drop regulators from the
LF00 family
(PDF datasheet) to accomplish this. Nice work!

You are using a prototyping board, which (likely as not) will be handled, jostled, plugged to, unplugged to, and generally roughed up. Pad-per-hole board is not your friend in terms of holding the pads to the board under heat.@Nay-sayersThis is a modification of a breadboard. It has the added bonus that it is both reversible and generally useful, qualities that not every entry on this site can claim. It has decent documentation and referencing, and some thought in implementation; again not something every entry here can boast. Lambasting this because it is simple is quite short-sighted: simplicity is a laudable goal. Too, make suggestions as to improvements and additions instead of whining that it is too simple or easy.@not_starmanUsing a divider would be unwise unless you have specific and/or very low current requirements. Changing the load across the (lower) divider resistor would change your voltage. Simply put, if you attach a load to the divider point, it is the same thing as placing an impedance in parallel with the lower resistor. Two regulators from the same source will maintain their voltages despite loading (within specification). Also, the divider would always draw power, which would decrease efficiency of the circuit.A suggestion for an addition to this circuit would be some current limiting. As this is a prototype, risk is high that a short could occur. A simple implementation can be found here:http://www.radio-electronics.com/info/circuits/diode_current_limiter/power_supply_current_limiter.phpthe design limits current by sensing the voltage drop across the resistor and using that to turn off the transistor. The sense resistor could either be fixed (for general safety) or adjustable depending on circuit needs.",

An
Android App for “testing”
the Windows
SMB2 vulnerability we covered last week
has been released. For testing? Yeah right! The availability of this kind of software makes it ridiculously easy for anybody to go out and cause some havoc. Go right now and double check that your machines that run Windows Vista or Windows Server 2008
are protected
(see the “workarounds” section.)

Head Bangers Beware: Motion Sensing Headphones

"ipod",

"tiltphone"
] |
The iPhone doesn’t have the market cornered on the use of accelerometers.
The tiltphone project
incorporates a three axis accelerometer into a set of headphones transforming them into a remote control for an iPod. A PIC16F690 reads in data from the analog sensor, translates specific movements into commands, and like the
Arduino iPod Remote
from last week, relays them to an iPod via the Apple Accessory Protocol. A quick nod left or right skips tracks, holding a sideways nod controls the volume, and setting the headphones down pauses.
This project is a bit older but we’re glad [anon] tipped us off as we hadn’t seen it before. There doesn’t seem to be any code or schematics available but because
the Apple Accessory Protocol is known
, it’s only a matter of working out how to interpret the sensor data. There is video after the break and if you pull off this hack yourself be sure to send in details for a followup.

Rotating Lego Dock Take Two

Last week we saw a
rotating iPhone dock built from Lego
. This week we’re happy to put up
another example of a dock made of these popular building blocks
. Thank goodness this one takes into account all of the sudden jolts that our desk is prone to by incorporating shock absorbing springs. The design is very sleek with a jazzy red scheme and a less-is-more attitude. We are a bit concerned about our expensive hand held falling out but then again that’s what the springs are for. Who can be the first to put together a step-by-step guide for building this one?

I have to second the content degrading thought.Personally though, lower case forcing, black and white pictures, and one hack a day, are un-needed. Black and white pictures have a certain artistic value, but the site isn’t impacted one way or the other over it. Lower case comments is just a gimmic.Limited hacks per day though, that could be a good idea. I’m too much of an information junkie to want only one tidbit each day. That’s honestly why I didn’t visit the site much before RSS. With only one post per day, I could catch up on months of the site updates in 30 min and I wouldn’t need to come back for months again. Of course the occasional hack would catch my interest and provide another 30 min of reading, but for the most part the site didn’t have much content so I forgot about it.Maybe just a limit of how many posts per day… or at certain times. Like 2 updates a day, midnight and noon. That will help store up content for more days and allow editors to filter some things out… like Lego devices that don’t even DO anything except sit there.To ME, the definition of Hack-a-day is a site that shows people taking existing things and making them do things they were not designed to do. A brand new project with an Arduino controlling it can be cool, but it’s certainly not a ‘hack’. The Arduino was designed precisely to do such things. It is not outside of design specs to make a machine like that.Now, if you yank your neighbor’s car engine and mount it outside your house as a generator to power your computer… maybe we’d all like to laugh at that. At least it’s really in the ballpark of ‘hack’.Slow your roll, take a deep breath, and make your goal to capture at least some of what we all love about hack-a-day. Fewer, high-quality updates will keep us around for a long time. Publishing 100 updates a week full of junk like this one will destroy your base, and even the fluff that like this kind of thing will fade away when you start posting “Two lego bricks connected at an angle to form a stand for your pen!” Detailed write-up: Brick one snapped into brick two and Viola!

The Cheap Vegetable Gardner wanted more automation than their previous
PS2 controller based grow system
. This time they set out to design
a full featured, compact grow controller
that can measure temperature and humidity as well as control a heat lamp, fan, and water pump. An Arduino provides USB connectivity and interfaces the solid state relays and sensors. The assembled project all fits in a box but we are left wondering how much heat the four SSRs generate and will it be a problem?

[atduskgreg]
posted this interesting setup to flickr
. He’s using two toy cars as a switch. He has wired into their metal undercarriages so when they collide, the circuit closes. We’ve
seen some
pretty nifty
home made interface items, but usually they are posted with a clear purpose or a project. This one is a little puzzling. Does he intend to keep using the cars or was he just fooling around? Is he working on a toy that does something when they crash? Was he merely bored and wanted to see what he could attach to his Arduino. We may never know.

1:35,200 Scale Train Is World’s Smallest

This train layout is so small it nearly defies photography as much as it defies expectations. Built by model railroad enthusiast [David Smith], this is a model of a model: an N scale (1:160) layout inside a Z scale (1:220) world! For size reference, the entire layout is shown under a ballpoint pen tip in the photo above. And it
actually runs!
Of course with this being Hack a Day you know there’s going to be some shenanigans involved. Pause
the hi-def YouTube video
at the 0:50 mark and see if you can puzzle it out first. The remainder of the video and [David’s]
project page
reveal how this all works, and it’s no less amazing even with the trick exposed. Check out his other
ludicrously small mechanical wonders
as well!

Color Changing Paint Display

We’ve seen
several
creative
projects
from [Sprite_tm] and this one sets a new bar. He got his hands on some paint that changes color with temperature. By covering a circuit board with the paint then heating the circuits he’s created
a heat actuated 7-segment display
(his post is
in Dutch
). Three seconds at about 1 amp is enough to turn the black paint white. When the segment has been disconnected for about one minute the paint fades back to black. Now that we’ve seen his concept, leave a comment and tell us how you’d use it.

Could paint “WARNING HOT!” underneath the colour changing paint (because they seem to go from black to clear).BTW Alsa also produce colour changing paint that cycles through 8 colours…http://alsacorp.com/products/xposurepaint/xposurepaint_prodinfo.htmYou could conceivably create a ‘full colour’ photographic display by carefully regulating the temperature on a surface painted with this. Perhaps via a scanning infrared laser or a visible laser shining on the rear side. Or a heat lamp shining through a stencil printed onto an OHP transparency for a simpler setup.I also found one of their YouTube videos where they’ve painted a sink which makes sense to me, a bathtub would be good too.Also found this:http://www.paintwithpearl.com/colorchangestore.htmThey sell the powder for US$45 which you mix with a quart (about a litre) of transparent base or other paint which is not too expensive.Great YouTube video!Could paint a light shade with it. When the light is on it warms up the shade and makes it reflective white (or silver), when off it reverts to stylish black.Ooh, ooh I’ve just had an idea! Paint black to clear colour changing paint onto glass or perspex to make a cheap window whose visibility can be controlled electronically. Need a way of heating it such as having two panes of glass with an air gap through which you can circulate hot air from a hairdrier or similar to make it clear. Like those ultra expensive LCD windows. Someone should try that, it would make a cool Instructable.Or how about interfacing it with optical sensors like a basic LDR with this painted on to make a temperature sensor. Hmm. Are there any applications where both temperature and light need to be sensed at the same time and it could be incorporated into the same sensor? In this case the resistance would be high anytime it is cold and/or dark and low when it is both light and warm. A solar hot water controller? A solar oven? Ultra simple glasshouse ventilation controller – painted LDR in series with ventilation fan and power supply?Lots of potential.

The friendly robotic bartender
we’ve covered
a
couple of times
before hit the airwaves last week. [Jamie], the inventor of Bar2d2 sent in a link to
video of the barkeeper in action
. The story runs from 0:30-4:40 and covers a bit about the build, the conversion to automatic drink mixing, and plenty of happy liquor-guzzling party goers.
We get a good look at the
drink ordering interface called Lazy Drinker
. It runs on a laptop and communicates wirelessly with Bar2d2. Looks like you can get your hands on the software for free but the hardware, either in kit form or assembled, is going to cost you. Want to see how the dispenser kits are put together? Don’t miss the
illustrated assembly instructions

We were a little surprised when we learned the
Mazda RX7’s
high beams were controlled by ECU, compared to typical cars using just a toggle switch.
Ubermodder
[Trent Bruce] realized how much of a pain in the rear end this can be if the ECU ever burns out, meaning no brights. By using a D-Flip Flop setup in a toggle configuration, he is able to
control his once lost high beams
. He also points out that if you plan to do any other electronic modifications to the RX7, you should be sure to pay attention to the unusual ground switching and the other crazy wiring under the hood.

[Niclas] sent us his
home made tube amplifier
. For the case he used a computer power supply unit, took out the guts and replaced them with the amplifier board. He based this build off of
an existing design
but took a more minimalist approach. The wooden face plate has an on/off switch, an audio jack, and volume control. Apparently, the tubes are floating loose inside of the case. We’d recommend a more secure mounting method for these delicate parts.

[Kevin] sent in his almost finished
open source dot matrix clock
. Sporting a hefty 40 x 16 display powered by a PIC 18F he has complete pixel by pixel control of the graphics. Combined with with a triple buffer he is at least able to output 15fps, with planned 30fps. While this has great potential for a clock, what about going further? Twitter updates, chat messages, weather updates, the current
airspeed velocity of an unladen swallow
; it will be tough to beat
the competition
without some more features. Either way, its an awesome project and we can’t wait to see it completed.

"content": "I am working on the software for my own LED matrix clock right now. 64×16 LEDs, 100Hz display scan rate, approximate parts cost £20-£25.I have no idea why this guy’s system is so expensive.Before starting I looked around and you can get 64×16 LED matrix boards on eBay for about £25, with a controller chip built in and SPI interface. I decided to make my own because I wanted some experience of handling the relatively high current (~1.5A max) and display refresh. I was only planning to do one 16×16 matrix but decided to do another three and make a clock with radio time setting (DCF77 receiver module harvested from a dead alarm clock).I looked in to going to LED-driver-shift-register route like Kevin did, but aside from the driver ICs being expensive it’s a fairly standard and uninteresting solution. Instead, I decided to use LM317 voltage regulators.I have one LM317 for each row of LEDs. They are set up to provide 3.2V, which matches the forward voltage of the LEDs so no resistors are required to limit current. Actually, it’s a bit higher because the display is multiplexed so I need to supply a bit of extra current, but is still low enough not to burn the LEDs out.The big advantage of using LM317s instead of transistors is that they provide the same fixed voltage (and thus the same current) no matter how many LEDs are lit. With transistors you have have to be careful to make sure the current is constant or the brightness varies with the number of LEDs per row that are on.For the columns I use ULN2803 Darlington drivers and ordinary 74LS595 shift registers. These are both really, really cheap compared to the kind of high current shift registers Kevin uses.My clock will be open source, I just need to make a web page for it. I hope it will help others learn about power control with microcontrollers (I use an AVR), as that is why I started it. Rather than just use an off-the-shelf single chip solution like Kevin did, I wanted to actually get down to the nitty-gritty of how the system works.If there is interested I might even get some PCBs made (and the designs will be open source too). The main problem I have is finding a suitable enclosure, because I have no real skill in making them. One idea I had was to use something like those wood-fronted clocks you can get, where the LEDs are behind a very thin wooden front panel and shine through it. A simple plastic box with wood veneer would probably do.",

Mine just uses MOSFETs on a demultiplexer connected to the 5V supply to turn on rows. You say that your end effect is that it puts out the same fixed voltage no matter what. Being a voltage controlled device (rather than current controlled like a bipolar transistor), the ideal MOSFET does the exact same thing which makes me wonder what the point of all those regulators is.I have been working on this project for 4 years with the current iteration 2+ years. I don’t believe off the shelf is a good description of this project whatsoever. The only part that could even be classified as off the shelf for this purpose is probably the LED sink drivers.

"content": "@Kevin: $71 for the PCB!? Have you tried SeeedStudio?Also, it might be worth trying to split your board into separate driver and display sections. The driver part is probably quite small, and then you can just use really cheap protoboard for the display part and a few wires.As for the voltage regs, they normally use two resistors to generate a stable voltage. The adj. pin is also connected to a transistor (BC337) which when turned on shorts it to ground. When shorted, the output voltage is only 1.35V which is not enough to turn the LEDs on.MOSFETs are certainly usable, but they have some disadvantages. As you discovered the BSS138 is not ideal for your project. It would be better to use a P channel FET and source current with it. Also, you have to be careful with board design and selection of the MOSFET because you can encounter problems like slow on/off times due to capacitance in the FET and the PCB traces. They also produce more heat and use more current than LM317s.As you have apparently discovered, most MOSFETs are far from the ideal mathematical model.Is the slow switching speed why you are limited to 15fps? Or is it the slow speed of the PIC? Even at 30fps you will get significant flicker. 50fps is about the minimum I’d say, so around 1ms per row for a 16 row display. I have tested up to about 300Hz on mine and could probably go further, but I use 100Hz to allow the AVR to sleep and do other stuff.The HT1632 seems like the best “does everything” IC available at the moment. I’m surprised you have been working on it for 4 years though. Don’t take this the wrong way, but it took me about a week to come up with the design and two weeks to solder everything up, testing along the way and writing the test AVR code and doing it all in my spare time. What made your design take so long? It seems fairly similar to the many other LED matrix display designs out there, so I can’t see why it would take so long to do, unless I’m missing something. In fact, it looks pretty much the reference designs in LED driver data sheets.I’m interested to see what sort of case you come up with. My idea was similar to your mock-up, but I’d probably make it out of one but of solid wood rather than panels if possible (I just prefer that, obviously it would cost a lot more). I have no skill when it comes to that sort of thing unfortunately. I may end up getting some pre-cut panels and just gluing them together.",

I couldn’t fit it otherwise.@mojo: I used Olimex and the boards would have been about $15 cheaper if I hadn’t forgotten to run a few scripts on the boards before sending them in :P.Literally the day after I ordered the boards I realized P-channel mosfets would have been better. If I end up redoing the display after this point I will definitely change to P-channel mosfets.The main reason for my design taking so long was my lack of complete understanding about this sort of stuff until about the last year or so. Until recently I have had no formal education about MOSFETs and such. Another reason was time actually spent working on the project. If I were to have worked on this continuously I could have probably had it completely finished in under 9 months (PCB ordering and all). I had several projects that have gone on during this one along with school taking more time than I originally expected. The PCB’s probably took the most time seeing as I had to learn how to route things properly (I had always just used the autorouter up until then). As for reference designs, I never bothered to find any except for one project that used an ATTiny to drive a 5×7 matrix. If it looks like the references in datasheets that is probably mostly coincidence.The speed is limited by the slowness of the PIC. If I were to re-do the board I would go with an AVR since it has a much faster top speed.I used to have the board split into two sections, but then I discovered surface mount soldering wasn’t too bad and so I put it all on one panel.",

It makes sense because it’s tricky for the designer to produce the exact Gerber output files required, but relatively easy for the PCB manufacturer since they have everything set up and know how it should all work. SeeedStudio also don’t place any major limits on the PCBs, like having to use certain drill sizes etc.I couldn’t have got the Retro Adapter project to where it is without them.Anyway, it’s cool that you are taking the time to learn. To be honest I studied electronics at college but never really got it. After finishing university I became interested in it again and somehow it all just fell in to place.I have to say, you picked a tricky project to learn on, and using a PIC probably didn’t help much. They are not a nice architecture, and as you have discovered at 4 clock cycles per instruction they are pretty slow too.The AVR is so fast I can do things like greyscales on it, which I am experimenting with. Anti-aliased fonts on an LED matrix.I am still deciding what to do with my clock. I will release all the schematics and code under the GPL. I’m not sure if I will do a PCB because it would make more sense to re-design using an LED matrix controller IC. On the other hand, that would be a less interesting design and less fun to build.

It’s the sort of thing you do once, then realise it’s a giant pain the arse and stick to the sensible options :)One advantage my display has over Sure Electronics’ one is that I can do per-pixel brightness. Thanks to having a very high refresh rate, I have tested 4 levels and I think it could go to 16, not that there would be much point in that.Another thing I find interesting is the possibility of non-multiplexed displays. You find them on some trains and buses. Multiplexing them, even at 100Hz, would result in the display tearing as the vehicle moves past stationary passengers. My guess is that they are either not multiplexed at all, or scanned at a very high refresh rate, or maybe with multiple multiplex sub-displays (say every 8 rows multiplexed).Oh, and I am looking for a white LED matrix.

[GuySoft] sent in this project. He doesn’t normally mess with electronics, but decided to give it a try. He chose a fairly complicated project to be his first, but seems extremely comfortable with it. This project was to
control his R/C car with a pic16f84
. That chip was chosen simply because it was the only one available at local stores. Though we’ve seen much more complicated projects in the past, he does a great job of showing exactly what has been done. He shares his thoughts and source code with us as well. He has express a little frustration about the closed source compiler he was using, so if anyone has any suggestions for him, he would probably appreciate it. The funny part is that he mentions that people would just tell him to “get an AVR”. We think the readers here will probably be happy with how he pulled it off.

Dropping that inline with the C code could be one solution (although, busy loops are certainly not very elegant).When I plan on needing some rough ms delays, I tend to set up a timer interrupt to occur once every ms, and increment a counter variable (or a couple if I’m on an 8-bit system — I never tend to have anything on long enough to overflow 32-bits).",

Don’t ask why, I just don’t want to mess with it.AVRs are probably expected to replace PICs in the future, still, in some projects PICs seem to be a better choice than AVRs. Correct me if I’m wrong, but due to their internal difference you can build a 50 MHz frequency counter using a PIC and no external prescaler (http://www.sprut.de/electronic/pic/projekte/frequenz/freq.htmand a ton of other projects like that one) but apparently you can’t do the same with an AVR. Please don’t make a flame war out of this post, I’m genuinely interested in knowing if this can or cannot be done with AVRs, and why.",

You can in circuit debug your code on most modern PIC’s and that’s a really useful feature. Programming speed is also very high, comparable to a bootloader. (on the 16-bit PIC’s there is in fact a programming executive installed, with which you get about 12kB/s programming speed)And if you need a cheaper programmer there are of course many different parallel/serial port programmers on the net.I personally hate the 10F, 12F and 16F series because of their instruction set, the fact that many of them have a banked SFR map and they have just one indirect addressing register is really limiting the power of these MCU’s when it comes to more complex applications. (and there is no reasonable free C-compiler available for them)I mainly use the dsPIC33F series from microchip because they have a lot of power (40MIPS, DMA, DSP) for less than $10!For simpler applications i recommend the 18F series because microchip offers a free C-compiler.As for the compiler I just use the microchip C-compilers which are free for academic use and generally produce very optimized code. (the C-compilers for the 16-bit PIC’s are derived from gcc; although full optimatisation is only available in PRO-version, but for most applications the limited optimatisation (-O1) is sufficient and when I need more optimized code I just write it in assembler..)I think the biggest problem of PIC’s is that microchip only supports Windows.

Yes, you read that correctly: electronic mail
carried by birds
. [Ferdinand] tipped us off to this story, which involves combining new and old methods in transferring data.
The Unlimited Group
, a firm in a remote section of South Africa, transfers loads of encrypted documents to a second office 50 miles away. A pricey broadband connection would take between 6 hours and two days to transfer a standard load (4GB) of data between these locations. On the other hand, Winston (seen above) can complete
an equivalent flight
within 45 minutes.
A memory card
is strapped to his leg, and using his wit and instinct, Winston finds his way home. For those without their calculators on hand, Winston’s bandwidth is between 7x and 63x faster than what they had before. If his flash card were to be upgraded to 16GB, that would be an instant fourfold increase on top of current gains. As [Mark] pointed out
on the Daily Mail website
, homing pigeons still need to be taken back to their departure point.
This solution still has its advantages over a courier: they are lower in cost, they work over longer hours, and have potentially faster delivery speeds. Multiple pigeons can be transported back at once, and released with data as needed.

CableCard Card Tuners On The Way

We were momentarily excited when we heard that
CableCARD compatible tuners will be available for purchase by the end of the year
. A card like this would allow you to hook up your digital cable to your computer and record programs natively. This has been possible for a long time with analog cable and
PVR software such as MythTV
. Up to this point, recording digital cable has required a
dedicated cable box and workarounds
to allow the computer to change channels.
Wait a minute though, the announcement was made by Microsoft? Indeed. Microsoft has been making a big push into the home theater PC market with
Media Center
. Redmond’s PVR offering is also limited to recording analog television;opening up digital would expand the marketplace for them. But here’s where it gets hairy: if you read the
Microsoft announcement
, TV shows flagged as CF (copy freely) are the only ones that can be recorded.
So, if we have this right: you shell out money for a new tuner then you pay more for the rental of the CableCARD. Both of these expenditures are on top of a digital cable subscription. And yet you can only record shows marked with a “Copy Freely” flag. Who makes the decision on which shows we can pay to record?

In the past those DRMd files would only play on the recording PC or an extender like the Xbox 360. No transcoding, no portability.3) Even outside of the CabelCard environmnet, media center has had HD digital recording back to XP days with ATSC over the air tuners. With Win 7 (and with the OEM only Vista TV Pack), you can actually record the handful of clear QAM digital channels that aren’t encrypted by the cable systems (mostly local networks).IMO, this original post needs a lot of edits, because the facts are pretty misunderstood as is.",

This means Tivo Series 3, ATI DigitalCableTuners, some set top boxes, and the occasional TV. The card is just a decoder, it contains no RF circuitry.

(But this doesn’t stop people from trying and then bringing it in for service when their computer doesn’t boot anymore)",

Centon’s website made a mention of linux drivers for one of their tuners (4 tuner model??). The other option is a costly buy of the HD-PVR to record from component video or even the HD-PVR + HDfury to record from hdmi. It’s sad that DRM like restrictions is hurting legitimate customers and making mythtv installation more expensive to reach comparable levels of tuner functionality.",

[Andrius] just sent in his robot
Rubik’s cube solver
. It isn’t as fast as the
solver we saw last year
but it also doesn’t require as many parts either. This project utilizes two claws, each actuated by just two servo motors. The thinking is done by a PC which calculates the necessary moves to solve the cube. Each instruction is then passed via USB to the AVR ATmega16 microcontroller that is responsible for the servo operation.
Right now it looks like the colors for each starting face have to be entered manually before a solution is calculated. We think [Andrius] is probably planning to upgrade this with the next generation of his software as he already has a webcam setup for this type of analysis.

Linux (via ILoader) Out For Nano 2G

[
Linux4Nano
] over at the [
Gna! repositories
] have just finalized a breakthrough for their
bootloader
project. Because the iPod Nano 2G has a
hardware encryption chip
, it could previously not be flashed with a custom
firmware
. By digging around in
some assembly code
(and working their magic) the team was able to
get Linux onto the 2G, develop drivers for its peripherals (screen, clickwheel and serial interface are a few), and
put all of that code into a package convenient to install by the end user. If you’ve ever considered
installing uClinux
(the ported distro) on your Nano, the [Linux4Nano] team have
made the iLoader
an easy place to start.
Update:
Closer inspection yields that the iLoader is not yet able to load uClinux onto a 2G because it has not been ported. However, it can reload it with other custom firmware which is still a solid breakthrough.

Classy Hard Drive Speaker Set

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front.
The project
is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is
an iPod dock
!

Disabling Your Cell Phone’s Mic For Security

[Dan] set up this
simple cell phone hack to disable his microphone
when he’s not using his cell phone. He had
read that the government can listen to you
using your cell phone, even when it is off. This concerned him enough to hack into his phone. He removed the expansion port and wired the microphone to a magnetic reed switch. A strong magnet located in the screen side of his flip phone opens the circuit when he closes the phone. He notes that you could always just pop the battery out of your phone, but then you are left completely disconnected. This mod allows you to still receive phone calls.

"content": "Anybody with the knowhow can hack into a computer these days can hack a cell phone because it typically has a computer operating system installed and regardless of the operating system the processes for hacking it are pretty much the same. (you can even install Android, one of the most popular cell phone operating systems, on your laptop as an operating system if you desire to do so, do a search for Android X86 to confirm) This means anybody who has enough desire can hack into your cell phone or other devices and listen in on your conversations as well as use the background noise to better determine where you are, this has been going on long before there was paranoia over the possibility.Having said that, not all people who desire privacy are conspiracy theorists or paranoid. In fact, most who are concerned about that subject simply want to keep personal things personal and private conversations with friends and loved ones private. I mean, if somebody you know trusts you with something they want to talk to only you about, you would not want others overhearing it and then passing that information on to others. If you know that everything you say will be heard by people you do not know you will be more likely to keep what you want to let out with somebody you can confide in to yourself and bottle it up inside which will lead to worse psychological issues later.There is also a more obvious aspect of this: if there are cameras and listening devices everywhere then nothing you say or do remains between you and people you trust. If there are cameras and microphones in every room you eventually find yourself being more careful of what you say and changing your actions to not look out of the ordinary. This is why putting a camera at the front of a store or building and making it as obvious as possible is a good deterrent to shop lifting and violence, if people know that their every action is being recorded you do not have to do much to control them because they will force themselves to not act out of the ordinary.That being said, if you have devices that are constantly watching and listening throughout your home and everybody is carrying something that is recording themselves and everybody around them, there is no such thing as privacy anymore. This means that you will never feel that you can have a space to be yourself for even a moment and this can be psychologically damaging, especially to those who do not fit in with the majority to begin with. Of course eventually those who do not fit in will adapt and change themselves to fit in, but invention and new ideas tend to come from those who do not think or act like the rest of us so our growth as a culture will be stunted.BEFORE YOU RESPOND:Notice that I had not mentioned the governments, businesses, agendas or 1984. The focus of this post is to explain why having cameras and listening devices recording you is not a good thing. Feel free to offer up any counterpoints but let’s leave the insults by people who do not even research news articles out of it.",

The “data center” room in San Francisco is real. Wiretapping innocents is matter of fact for the NSA, CIA, FBI, and DHS- and they will get away with it until people start doing something about it.The only difference between people calling this man crazy and the man who hacked this brilliant simple hack are AWARENESS and CONCERN. You don’t have to think you’re being targeted to care about this issue. It’s basic self defense.You don’t buy life insurance if you weren’t concerned something could happen to you, do you? You recognize the possibilities of bad things. This man shows his preventive measure with a hack.So what are you going to do? Sit there and not care?

Blue Light Special: Earn $10 By Installing Spyware

Ars technica
is reporting on the ruling from the FTC about the software shenanigans of
Kmart and Sears
. The marketing geniuses behind the parent company of Sears and Kmart decided they needed more information about the users of their website.
Their solution
? Offering $10 to users who install their custom software which phones home with data on just about everything they do on their computer. Not content with just browsing habits of webites, the software apparently recorded everything the user did online, including
secure sessions
. Under the
settlement
(PDF) with the FTC, Sears says they will stop collecting data and promises to destroy any and all information they’ve collected so far. Selling what websites you’ve been to, how much money you have, which prescriptions you take and what products you’re interested in for the low low price of $10 seems like a bargain.

Laser Spiro Made From Junk

"green",
"laser",
"spiro"
] |
Sometimes we need someone like [FireMyLaser] to show us that you really don’t need things like custom PCB’s, expensive tools, or laser cutters to pull of a hack. His
laser spiro subsists mostly of toothpicks, hotglue, and determination.
It is a two motor spiro with a base motor and a motor mounted in a spinning cage. The cage gets power through brushes much like
other projects we’ve covered
. See a video of it in action after the break.

Pictures From Space For $150

Ever wanted to be able to launch a balloon into space, track its location via GPS, take some photographs of the curvature of the earth, and recover the balloon, all for the low low cost of $150? [Oliver Yeh] sent in his teams project,
Icarus
, which does just that. The group of MIT students found that they could use a weather balloon filled with helium to reach heights of around 20 miles above the earth; their particular balloon achieved 93,000 feet (17.5 miles). Then, utilizing only off the shelf components with no soldering, conjured up a GPS tracker using a Motorola i290 Prepaid Cellphone. They then used a Canon A470 loaded with the
chdk open source firmware
to take pictures. After seeing
the results
of their launch, the team hopes that this could rejuvenate interests in science and the arts.

Steady fermentation temperatures, usually at about 65 degrees Fahrenheit, are an important part of brewing beer. Because of this, the wort (unfermented beer) is often temperature controlled during fermentation. [android] needed a
temperature controller for fermenting beer
in a chest freezer. Much like the
energy efficient fridge hack
from last month, the chest freezer is switched on and off to achieve the desired temperature. Instead of buying a controller, [android] built around
an existing design
. His project uses a
solid state relay
to switch an outlet on and off.
The temperature is controlled by a home thermostat. He removed the thermistor from the unit and extended it with 24 gauge wire so that it can go inside of the chest freezer. Utilizing a junction box, the freezer is plugged into one switched outlet and controlled by the thermostat via the relay. The other outlet is unswitched and provides DC power for the relay using a wall wort transformer. Although this thermostat cannot be set cold enough for lagering, it is
perfect for keeping kegs
at the
correct beer serving temperatures
when not being used for fermentation.

"content": "Humm, there’s all kinds of things that will get in the way of this working. Off the shelf, the freezer probably has a timer to control the defrosting cycle. So cutting the power would essentially stop the timer making it hard to guarantee the freezer will go into a cooling cycle when ever powered up. Also, many (if not all) off the shelf house thermostats will include a back off timer so as not to cause undue stress on the cooling system. I think the average temperature will be obtainable. But I think the actual temperature will very depending on the randomness of some of these (now unwanted) features.Did anyone look deeply into the thread and see if these issues were considered?",

Then the stick the brew off to the side for the next week or two before you bottle/rerack.Even lagers are pretty simple as a standard fridge is able to get it to the correct temperature, or if you live in a cooler climate, just keep it in a 4 seasons room or attached garage that gets enough heat to stay above freezing.

How To Build A Life-sized Electronic Game

We’re very impressed with [Steve’s]
Electronic Snowball Fight game
. It consists of two life-sized players standing opposite of each other. Each can throw a snowball or duck, the object is to hit the other person and not get hit yourself. He’s utilized a lot of good building techniques that could be easily adapted to other types of game play.
For the outlines of the players, [Steve] took pictures of himself standing, ducking, and in a throwing motion. Each picture was used to generate an outline which was then stenciled onto some
Masonite
. He then drilled holes along the outline and pushed christmas lights into them.
One string is used for each circuit.
A solid state relay board was built to take care of switching the strings of lights on and off. [Steve] housed this in a weather-proof utilities box and used extension chords to facilitate connecting the lights. The
SSR
is connected to the controller using CAT5 Ethernet cable. The controller is an Arduino in conjunction with a 595 port expander board to provide enough input/output pins for the game.
Two delightfully creative parts of this project are the buttons and the scoreboard. The buttons are made to match the scale of the game. [Steve] picked up four used push-style lights, patched into their momentary push switches, and added LEDS for feedback. For the scoreboard he used reflective tape and LEDs with a foam bezel to create 7-segment displays.
Well planned, well executed, and an all-around great build! Don’t miss [Steve’s] step-by-step explanation video which we’ve embedded below.

The
HAL two-leg exoskeleton is now available
for rent in Tokyo for $2300 per month. We saw the HAL in
our power suit roundup
from last year. There is footage of this lower-extremity suit demonstrated by three people. The video is a bit creepy because the they are apparently just out for a stroll in the city.
We really do want to see this succeed. Every time another advancement in exoskeletons comes around we glimpse the future of mobility and freedom for victims of paralysis. The machine is controlled via an interface that picks up electrical impulses on the surface of the skin. The built in battery provides power for up to five hours of operation before recharging is necessary.
[Thanks David]

There was another exoskeleton leg set that might have been on here a while back that the operator sat on a banana looking seat between the legs, you would need something like that to help people walk again. This might be usable for people who have suffered something like a stroke that affects the operability of the joints, where they can still bear weight, but their joints are essentially locking to support their weight.",

We’ve seen some impressive mods for the popular video game Rock Band, from
new cymbals
to an
air powered kick pedal
, but we cant say we’ve seen someone go as far as the folks over at EDrums. They start off making their own
mesh heads
, a
junction box
to connect everything, and then a
base
to hold it all together. It is definitely some dedication and hard work for a setup that will only be used in the living room in front of the T.V. Check out some more video of it in action, and a comparison to the original Rock Band drum set, after the break.

As an old rock muso I think there is a very real chance that some introduced to drumming like this will continue on to become real drummers; certainly more so than the similar guitar-based games. Nice build, very good writeup.His detail on cheap and durable drum pad construction alone makes this an interesting article; certainly a cut above the more typical practice pad circle of thick ply with tractor innertube glued to the face and maybe a piezo glued to the back.But as a tech, what is this *fetish* here with micro-controllers?There are two sensible ways you can go; follow the many builds that use piezo triggers into individual damped oscillatory circuits (e.g. Practical Electronics UK a few years back); or use a micro-controller to spit out MIDI codes so you can voice *anything* on a given pad. Each method has strengths and weaknesses depending on where you go next (e.g. performance or recording).While I have a state logic (non-PIC) circuit sketched out for a pedal clavier-to-MIDI sender I know there is a PIC-based solution on the net that would be better, *but* I can’t see the point of doing damped resonators in *code*.A particular problem with amplitude granularity arises with a signal that must decay away such as a splash cymbal – as you get to the tail of the decay the steps in amplitude become apparent and are annoyingly unnatural. Been there.Analogue resonators for each channel are about as complex/simple as a fuzzbox build so its a good “third project”; they all differ depending on what drum or trap they are imitating (and present a rich field for modding and tweeking); offer the opportunity to learn a lot in a small project (resonance, noise, bandpass and envelope shaping); allow direct control of resonator characteristics to get just the sound you want; and don’t require a third-order post filter to block the sampling frequency.By the time you add the required pre and post processor analogue conditioning it will make the direct approach look simple.Then, if you really must add code, what also makes sense is using a micro-controller to trigger these analogue voicing circuits to get a very flexable drum generator/beat box, bit like a player piano. Likewise a MIDI to analogue resonator interface.With an analogue solution *touch sensitivity* which is required for expressiveness, is easy but a serious complexity with a coded solution.",

It started with a simple need: keep tabs on
SparkFun Electronics
’ in-house
kegerator
so the beer won’t run out at inopportune times. But of course SparkFun and “simple need” make strange bedfellows…throw
beer
in the mix, and you know this can’t end well. The result, as you might imagine, reads like a who’s-who of electronics hackery buzzwords.
Arduino
? Check.
Custom PCB
? Check.
Web interface
? Check.
Twitter feed
? Check.
They’ve assembled a
nice build tutorial on how this all went together
, including code, example circuits, an explanation of some of the sensors used, and links to other tutorials for such things as Twittering and persistent storage in EEPROM using Arduino. Not to mention the eye candy: a custom Arduino shield (solder mask and all), custom acrylic tap handle, custom SparkFun pint glasses. They never do anything halfway, do they?

[bugloaf] tipped us off about this flower power hack. University of Washington researchers, [
Babak
], [
Brian
], and [Carlton] have
developed
very low power circuits to run directly off of trees. This builds upon the
work
of MIT researchers and
Voltree Power
. A voltage of up to around 200mV is generated between an electrode in a tree and an electrode in the ground. Identical metals can be used as electrodes as the process is not like that of a
lemon
or potato battery. The significant development here is the use of a boost converter and exceptionally low power circuits. What kind of applications can you come up with for this source of power? Maybe you could try to combine this power with the power from
donuts
and
hair
.

I recently did an experiment where I was trying to measure the electrical resistance of soil between two identical aluminum posts pounded into the ground about a meter apart. My efforts were frustrated because I was measuring very different resistances depending on which way I hooked up the ohmmeter. When I switched over to measuring voltage, I discovered why: there was about 0.15 volts of potential appearing across the rods. I figure some kind of differential galvanic effect was taking place. Even though the metal was the same, the soil (electrolytes?) were different in the two spots. Might the tree and soil simply be corroding the two nails at different rates, thus acting like a battery?",

There’s only been two real techniques (without requiring some complicated outside energy source, such as flicking a switch and using the inductive boost to start a step-up converter) i’ve seen that can boost voltages below .7v (usual limit with silicon devices)–use old germanium transistors (NTC or whatever that company was called sells ’em) or use ALD’s special zero-voltage gate threshold MOSFETS (real cool stuff, btw)",

I would guess that it is just a concentration gradient that they are capitalizing on.In terms of the power electronics… 0.2V coming out in the micro watt scale is not a lot of power and really difficult to work with. I have yet to find any commercially available power converter solution that can boot strap from that level. It is only recently that that amount of power would even be considered to be useful.We are continuing to develop a power converter that can boot strap from 0.3v and a little lower to a usable voltage. At these tiny voltages, you are close to the threshold tolerances of many of our components, its not easy.",

Low-cost ARM7 Prototyping

Do you find that the capabilities of your current microcontrollers are holding you back when you
try to take over the world
? Moving up to
ARM7 architecture
will put your projects in the same arena with the iPod and the Nintendo DS.
The
BlueBoard-lpc214x is a prototyping board
with a lot to offer. It incorporates two RS232 connections, USB, VGA, SD card slot, piezo buzzer, JTAG, audio out, PS2 keyboard connector, and a 2-line character LCD. The processor is an NXP Semiconductor LPC2148 with 512KB of programming space and 32+8KB of ram. The board also includes a 256KB i2c eeprom. This is a lot of prototyping power, but the
low purchase price
knocks our socks off: $40.90! Sadly, shipping would cost us another $20.43 but that’s still a lot of functionality for around $60.
Sample code and schematic are
available for download
. All of the pins for the microcontroller have jumpers and there are rows for pin headers around the processors if you want to patch in your own hardware. We’ve seen other
ARM boards that make use of pre-existing shields
. We would love to see someone remove the processor and implement Arduino-like shields for different processors outside of the LPC214x series. Promo video after the break.

We found
The Old Robots Website
this morning and ended up spending way too much time there. It’s a display of mainly consumer robots, though there are some custom jobs tossed in there too. Ranging from silly to awesome and everywhere in between, we found tons of great information. By strange coincidence, we saw
Arok
in a
documentary about eclectic homes
last night. Arok’s creator explained that not only is he an amazingly versatile robot, Arok is also going to be the medium for communication after his creators death. That makes him even creepier.

Everyone’s favorite open source game console,
the Uzebox
(also cloned as
the Fuzebox
), just got a new feature hacked into it –
a video player
. At reduced quality (8-bit color), the Uzebox was able to play ‘The Matrix’ off an SD card @ 30fps plus the audio @15kHz. That’s a pretty impressive feat when one considers it is running on
4096 bytes of RAM
. The video file had to first be converted into a series of pictures through a Photoshop macro in order to be playable. A Uzebox can be built with little more than a few resistors in addition to an
overclocked
ATmega644P
, and
AD725
(which has been skirted
in certain incarnations
).

S.P.A.R.K. Beginer Robotics Resources

We love to see educational resources appear. iRobot has put together
Starter Programs for Advancement of Robotics Knowledge or S.P.A.R.K
to serve as not only education, but amusement with the purpose of getting people interested in robotics. With sections divided into different grade levels, it is obvious that this is mainly meant for school aged kids. There are some games as well to keep them amused when they need a break. We looked around a little bit and it seems that they are still fleshing it out. We hope to see some structured content specifically created for education of youngsters. Right now it is mainly links to other resources.

Cain And Abel: Windows Password Recovery Utility

As far as password recovery utilities go,
Cain & Abel
is by far one of the best out there. It’s designed to run on Microsoft Windows 2000/XP/Vista but has methods to recover passwords for other systems. It is able to find passwords in the local cache, decode scrambled passwords, find wireless network keys or use brute-force and dictionary attacks. For recovering passwords on other systems Cain & Abel has the ability to sniff the local network for passwords transmitted via HTTP/HTTPS, POP3, IMAP, SMTP and much more. We think it is quite possibly one of the best utilities to have as a system administrator, and definitely a must have for your toolbox.

40 Years Of NERF

In 1968 a guy by the name of [Rey Guyer] came up with an idea for a game
. It involved foam balls as game pieces. After failing to sell the game to Milton Bradley, he approached Parker Brothers. They bought his idea but ended up tossing the game itself and just marketing the foam ball. Named after the padding used on rollbars in offroad vehicles, Nerf balls were an instant success, 40 years ago, in 1969. Many of us have fond memories of Nerf, even before everything they produced was a weapon. That’s not to say we don’t appreciate the Nerf weapons. We certainly have seen some hackers do
some fun
stuff
with them

In-depth MAME Cocktail Cabinet Build

Recently, a friend of ours got married who is a Ms. Pac-Man fanatic. His best man set out to fulfill the groom’s dream of owning a Ms. Pac-Man
cocktail cabinet
. The problem is that the unit he was after was selling for $2500. It’s great to buy the real thing (and with guest contributions he did,) but if it’s not available consider building your own.
[Alex] has put together a comprehensive
guide for building a MAME cocktail cabinet
. Unlike the
mini-cabinet we saw last week
, this is intended to be used sitting down and features controls on more than one side. His guide details the use of an original arcade CRT or an LCD flat panel, high-end controls via an
I-Pac 4 controller
, and a PC running
MAME
and
MaLa
software for Windows. The result is a professional looking build with controls on three sides of the table.

How To Download Books From Google

If you want books, but don’t want to pay for them, there is a better way than walking into your local book store and pocketing them. Try grabbing them online, from Google!
Everyone must be aware of the
Google Books Library project
by now. If you’re not, it’s basically a way for Google to ensure all of the world’s book content is accessible and searchable. Through the Book Project, Google works with libraries to scan and archive their older and out of print materials. Up until recently, viewers of books in the Google Library Project web space were limited to viewing books within the browser. Not any more.
Google Book Downloader
is a utility that rips books from Google and saves them as PDFs so you can view them with any device or desktop that can view this file format. Using Microsoft’s .NET framework, the Google Book Downloader application allows users to enter a book’s ISBN number or Google link to pull up the desired book and begin a download, fishing off with exporting the file to a PDF.
Full setup instructions and download are available on Codeplex
.

But I guess you don’t read much do you? (game reviews or walkthroughs doesn’t count)IMHO Google books works very well as it is. It is very lightweight and doesn’t require third party plugins (like most of Google services).“So this guy wrote a program to automate a process. If they change their method, the guy will just update the program or find someone else who knows how to do it.”If they start using some proprietary browser plugin to obfuscate the code then, TBH, I don’t really believe a guy who writes code in .NET has the skills and ability to interpret the plugin’s code.– And that is why I’m pissed off! I don’t want more fscking plugins!",

Though not much info is readly available about it on the web, [
Joe Carruth
] is trying to build publicity (and venture capital) for his home-built solar electric generator. At its essence, it is a
Stirling dish system
with an adjustable composite mirror surface. This means that instead of having to rotate the entire contraption in order to follow the Sun, [Joe] only has to make the mirror segments pivot. A
Stirling steam engine
at the tip converts the energy into the movement used to generate electricity.
Solar power plants (or ‘farms’)
that are emerging are beginning to consider the advantages of using more efficient Stirling dishes rather than less efficient
solar panels
. If anyone has an idea as to how [Joe] can automate
sun tracking
for the mirrors, please post it in the comments. A couple more videos on the topic (in general) are available below:

I think the easiest thing would be a set of 4 sensors that sets up a light gradient that could then be used for tracking and provide a measure of when there is enough light to power the system. The absolute cheapest way to control things might be some op-amps, but I would be concerned about the effect of temperature on the whole thing. A micro controller would probably be better, but I think that will increase teh cost of the whole thing.My other thought was, as long as the geometry of the system is fixed, then you could have a camera or cameras that track the sun and based on the fixed position of the Stirling engine relative to each mirror, updated the array. It is scalable to a lesser degree so long as the algorithm can handle an array of variable dimensions and there is address space for each new mirror.All this assumes that the differences in the angle needed for optimal power differs enough between mirrors to warrant individual mirror tracking. Maybe segments of mirrors could be grouped together. This may not result in max power, but the difference might be small enough that it is not a big deal. Still, if individual mirror tracking can be done economically, why not give it a try?",

"content": "Back when I was in high school (yeah…20 years ago!), my friend and I build a solar tracker for a science fair project. It was dead simple: two photocells, two op-amps (741 comparators, if I recall), and a handful of resisters. The photcells were placed behind small black tubes in order to provide a rudimentary aiming system; when the sun shone straight down the tubes (one cell was on each side of the dish), and the current was the same on each side, the servo held still. If one sensor showed brighter, it turned the dish until they were even again. We used limiter switches to stop the rotation at the ‘morning’ and ‘night’ locations, and when the ambient light fell to a low enough level, we sent the dish back to the start point until the sun came up again.Problems with this hack mainly came from overcast skies causing the CDS cells to not read anything, resulting in the dish sitting still all day; also, a long period of overcast followed by sunshine would make the dish stop following the sun, as it wouldn’t catch up again. Those problems could be fixed by using microprocessors such as an Aurduino. In this system, consisting of many smaller segments needing control, I would link them together in a parabola, and then shift them all at once.",

It’s probably also a lot easier to get a lot of small mirrors than it is to make an effective single dish.The boiler is quite chunky, having it mounted at the center of a dish could block a lot of light. That said though, he does have it set in the middle of the array anyway. Why not just adjust the angle of the mirrors and have the boiler more easily accessible on the ground? He’s using it as a parabolic when he doesn’t need to. Especially if he’s manually adjusting all the mirrors anyway.Also as Climatebabes points out, it’s a full-loss steam engine not a Sterling.And he says it’s hooked up to a 12Kw generator, not that it’s actually producing 12Kw.",

"content": "Start with the mirrors focused from the ‘boresight’ (perpendicular to the mirror array) to the target–so that if the Sun were on the boresight, each mirror would illuminate the boiler.Now, if you rotate every mirror by the same amount (eg. 23 degrees left, 5 degrees up) then every mirror will focus the same direction (46 degrees left, 10 degrees up) onto the target.So all you need is some linkage or other mechanism to rotate all mirrors by the same amount. This can be done with axles, gears, and chains. Only two motors are required.(And the mechanical adjustment that allows you to adjust the mirrors for boresight pointing, which you only have to do once. A pivot and two adjustment bolts will suffice.)Note that I have only verified that this works in one dimension, but my guess is that it works in two.Power output is proportional to the cosine of the distance from the boresight, so you do lose efficiency, but you gain in not having big moving structures. If you lose 20% efficiency, but can build 50% more for the same money, you win.For more efficiency, dish the mirror segments. This can be done simply by the stress technique (make them out of thin glass supported around the edge and pulled back in the middle). Precision is not required.The control system is simple: just move the ganged mirrors simultaneously left, right, up, down according to where the hot spot falls on the target. If you totally lose pointing, you can hunt for it with larger movements.Control it all with an arduino, just so that people on this site will complain.",

If you align a trough on the east-west, and make the length of the trough long relative to the distance between the trough and the focal line, most of the light will land on the focus throught most of the day. Then you only need to adjust one axis. Make the trough out of long parallel slats and adjust the focus as the sun’s path shifts north-south through the year. These would be small adjustments that could be made infrequently, so you could do it manually on a small scale.Alternatively, align the trough north-south. In this case, it might be best to use a plane layout instead of an approximate parabola. This arrangement would have to track the sun more extensively, but it would still only be one-axis. You would, of course, gather more light per unit area when the sun is near the horizon, at the expense of additional complexity over an east-west arrangement.Remember, of course, that black tubes make very good solar boilers, and are safer at high pressure.",

As the boiler seems to output steam via a flexible hose it shouldn’t present any great engineering challenges.I’d be interested to see how much water this uses in the course of a day, and whether the boiler could be replaced by a commercial Stirling.

I’d connect up to the individual mirrors with ~1/4″ round stock and some universal joints from a cheap Harbor Freight socket set. Seeing as this is a prototype I’d just epoxy them together. You might be able to use a braided line or cable, like the Dremel-tool cables, which would simplify things a bit.The mirrors would be aimed with simple cams that rub up against a bolt set into the frame.For now I’d cut them out of hardwood and run a strip of brass or something along the edge. Adjusting the bolts and adjusting the timing on the cams should allow me to adjust the position fairly accurately.To account for seasonal adjustment I think I’d use a set of motors and screws attached directly to the frame.The whole thing would be driven by a microcontroller.This way you’d minimize the expensive parts, the motors. You’d only need one motor per row, one motor per column, say four motors for seasonal adjustment. Stepper motors are cheap and would work well enough, though servos with gear reduction would probable be better. Weatherproofing it would be kind of a pain in the ass, but it should be manageable. If you’re in a wet climate then grease the hell out of everything, dry climate then dry-lube the hell out of it.Someone mentioned that it’s important to be able to invert the mirrors to help keep them clean. I think you’d be able to use the seasonal-adjustment motors to flip the whole mirror-frame over. Maybe not all the way, but it should be good enough to get the surface of the mirrors out of the rain, etc…",

"content": "I think someone already said it- the advantage of a system where the mirrors remain stationary rather than a single large mirror is the spaces you can put such a contraption. One could place many small mirrors on a roof – one could not place one very large parabolic mirror on a roof.The cost of having each mirror being controlled by its own system increases cost, but it also adds a great feature of expandability. If you designed the mirror layout around a center point and only had to set up each mirror with dip switches as to it’s location in reference to the center point then as one wanted more kW potential then you just buy a few more mirrors to add to your system place them and set them up with it’s location. Almost a plug and play system.Doing so would mean you would have to have solar positioning ability and time ability in each mirror but maybe the center point of the grid could house a box that would provide that via lan interface to each mirror set up via a small wireless network system. Or you could just address each mirror and run it from a single remote computer with a small program that would take into account each mirror location from the center reference point and focal distance.Individually controlled mirrors would make this the most versital sytem.",

IIRC, the folks as american science surplus (who had a large lens in their catalog) said that on a sunny day they could melt pennies with it. Maybe the fresnel doesn’t transmit as much light as what is reflected from a mirror?

Drilling precise grids without a
CNC machine
can be tough to pull off. [Ookseer] has come up with a nifty method for
dilling aligned holes with a drill press
. He uses a right-angle jig on a Dremel drill press with stacks of business cards as spacers. The same number of cards is added between the substrate and the jig to space each new hole evenly. This method comes in handy when drilling grids in an enclosure for speakers, temperature sensors, or for an aesthetically pleasing design.

So much for the X direction, for the Y you would have to move the fence in 1/10 inch increments. But most boards are laid out w/the IC aligned from left to right (you know what I mean). So it should be easy to drill multiple rows of 1/10 inch holes using this technique before moving the fence.",

Last week we showed you the ingenious
hard drive enclosure made from a broken Game Boy
. We caught up with [_n3o_], the person responsible for this mod, and he was nice enough to share some pictures of the inside of the project. Let’s get down to business and take a look.
[_n3o_] opened this project back up and took these pictures by popular request. Here’s the overview of the guts. You can see the 2.5″ drive on the right. The circuit board on the top is the SATA to USB converter. The two gray cables are to relocate the LED and USB ports. He did mention that before taking these pictures he swapped the 80GB drive out for a 20GB one in order to use it for another project.
Here we see the inside of the rear half of the Game Boy. The board all the way to the right is the original headphone connector from the Game Boy. At the top the volume control dial can be seen hot-glued in place.
Here is a closeup of the original headphone connector and volume dial of the Game Boy. The dial has been cut in half and glued in place. Both were left in the hand-held for a realistic look.
This is a closeup of the SATA to USB adapter that [_n3o_] salvaged from a generic 2.5″ external USB hard drive enclosure. A second USB socket was connected to the board using some ribbon cable in order to locate the USB connector in the same place the
Game Link Cable
is normally found. The LED was removed from the circuit board and relocated to the front of the case using the gray cable on the right.
Here is the front case of the Game Boy. Cardboard is used to keep the control buttons in place. The electrical tape to the left covers the back of the screen. You will remember from our original post that [_n3o_] simulated an image on the screen by removing the reflective backing from the LCD screen and put a paper printout in its place. The LED from the hard drive enclosure is located in the battery indicator window of the gaming unit. The gray cable seen here connects that indicator to the circuit board in the back half of the unit.
Voilà, the finished product. A peek inside makes this project even more delightful. Thanks for sharing those extra pictures with us [_n3o_]!

And I say drive(s) because you could probably fit a small RAID array into one of those suckers – the ones I’ve cracked open have been mostly empty space.Ohhh…ok, so put in a hard drive connected to an arduino or pogoplug or hacked iPod. Connect the record player’s audio output to the audio input of whatever device. Set it to automatically start recording when it detects sound and stop after x seconds of silence. Add a switch that will disengage the motor and allow the record platter to be used as a giant clickwheel to navigate through your music collection. Add a screen in there somewhere (possibly a TV out?)Ok, now someone build it.",

Arduino Crib Rocker

Anyone with children will understand the value of this project immediately. This is an
Arduino controlled sound activated crib rocker
. [Lars] built a custom suspension system for his baby’s crib which allows a servo, mounted to the floor to rock it gently back and forth. Ok, maybe it’s a vigorous rocking, but that’s what some kids want. At least he’s safe and
moderately immobile
. He had to make a custom amplifier circuit to get his microphone working with the Arduino. It seems to all work perfectly now, triggering to begin rocking when it detects the baby’s cries. This should buy them a few extra minutes of sleep until the baby is truly hungry or annoyed. You can see a video of it in action and download the Arduino code on the project page.

When we first posted [Matthias_H]’s
USB reader for SNES game carts
, it was met with enthusiasm. The snega2usb allows you to play SNES and Sega games on your pc right off the cartridge. The latest revision is even more amazing than the first. [Matthias] has added the ability to read
Sega Genesis/Mega Drive
cartridges as well as the ability to save games directly to the cartridge. The board has also been updated from the rats nest it used to be to a smart looking dual sided PCB. So far [Matthias] hasn’t had any trouble reading cartridges, even ones with the
SuperFX
chips. [Matthias] also
launched a site for the project
where the lastest information on its development can be found. [Matthias] is getting close to a production version which will feature better firmware, console quality connectors and a shiny case.

Otherwise, see below.@chris: it appears you are easily saddened :-) There will of course be a public release of the source code, once it is polished to a point where I could give away the source without losing face. Until then, allow me to sell a bunch of units so I can at least get rid of my debts. The wiring is more or less trivial. Take a datasheet of your favorite USB microcontroller, marry it to your favorite SNES/SEGA cartridge pinout document, and you’re done.@Mr. Sandman: Is this a part of some Things Mr. Sandman Wouldn’t Consider Buying Blog, or am I missing your point?",

(although the site at least now does say ‘well below $100’).Someone who has a console and some games in a box is not the target customer really. Someone who has nothing and wants to get started playing older games for nostalgia is not the target customer.For someone who had a console(s) and the console(s) have long since died yet they have 100 cartridges that they can’t play unless they re-purchse a console (good luck on what condition you can find one in) may find this very useful. Being able to play the box full of games they used to enjoy without the chance of buying a brick console on ebay or buying one that works but will die soon anyway seems to be a valid goal to me.I realize we’re talking to the DIY crowd here, and some people just don’t want to actually pay someone for their work no matter what though. I don’t think the whole community is that way, but as one poster said it, even if the parts cost $100 he’d rather buy them for himself and put it together instead of giving money to another person.I guess I can see some kind of logic there with re-using parts, but not after you look at the device (which is NOT a bunch of resistors that could be re-purposed). And c’mon, we blow $100 on tons of stuff as electronic geeks. You really can’t stomach the idea of one of our own getting a little monetary prop for some hard work that provides real benefit to people?You turn a hard drive into a clock, cool. But nobody was lacking a clock before. Still, I’d bet a few people might be willing to buy one versus make one. Like if I had all those spare parts sitting around then I’d make one, but I don’t, so I’d have to destroy a hard drive to make one and buy all the components at full retail in low quantities. I’d buy some of these projects completed in a heartbeat if they were available and I’d be happy that I was supporting a hardware hacker’s next project.I get the idea of being cheap, but you won’t even *consider* the idea of supporting another human being that is contributing to society? Really? *sigh*",

Which, in the video, lead to the problem that a couple of special characters from the cartridge ended up in the filename. When I “renamed” the file in order to make it readable, only its FAT16 entry was changed but it still referred to the same ROM data.From the snega2usb’s point of view, at no time there is more than 1 byte from the ROM/SROM being stored in its memory, so IN PRINCIPLE it is possible to randomly access the cart data. In practice, any SCSI read access always gets an entire sector of 512bytes. Also, most emulators do load the entire ROM file before executing it. This is to avoid read/write delays during execution, and reading the whole thing is the only way to check the contents against the checksum. So, by the time you start playing your game, it will no longer be read from the cartridge but entirely from your computer’s memory. If you WANT your emulator to crash upon cartridge removal, just like the real console, I can have the snega2usb deploy a special hotkey which tells it to ;-)",

We’ve seen
Z80 processor based computers
before but they usually use a printed circuit board to easily and reliably connect all the components. [Marton] sent us
his Z80 based computer
from a while back that is built entirely on prototyping board. He made his own video board that utilizes a TV as the monitor and his own mainboard incorporating a keyboard controller. The system runs at 4 MHz, has 32k of ram, and runs [Marton’s] own system software which he has posted. Its quite impressive and we love the protoboard porn with thousands of grey wires running everywhere.
[Marton] used
the resources on
[Hans Summers’] site
for his project. Make sure to check it out if you’re interested in a broader
background concerning DIY Zilog Z80 computers

We spotted this video of a
delta robot
today that seems to be powered by an Arduino. We were wondering when we would see this, happen. The source code is available on the project page. We really like the mouse control, its just fun to watch. You may recall that we recently covered some
slightly more complex delta robots
.

We’ve brought you
an HDD clock in the past
, but [mb1988] tried to bring
his project
to another level by fully documenting it (in Polish). Inspired by
[dzgdzzh]’s version
of the same invention, [mb1988] decided to reverse engineer it (as well as make a few changes) and base it on
the powerful ATmega128
. Since this clock, along with most HDD clocks, can only display solid lines of radii, it cannot be used to display text. However, color schemes and animations can be toggled using a remote control. The housing itself is also pretty impressive. The back part of the enclosure was molded
out of Rayobond
, while the front was simply the original HDD case but spray-painted black and etched with some original artwork. The source code, schematics, and PCB layouts are freely available to download on the project’s thread, but you will have to
login to the forum
to access them.

C64 Emulator For IPhone Approved — Minus BASIC

After a lengthy process that had previously met with rejection,
Manomio’s Commodore 64 emulator for the iPhone and iPod touch
has finally been accepted by Apple. This marks the first time a multi-purpose emulation title has been approved by the App Store. The $4.99 C64 app comes bundled with five fully-licensed classic games, and additional titles can be purchased and downloaded directly within the application.
App Store policies prohibit software that could run downloadable code, which barred most emulation attempts in the past. A couple of Sega titles worked around this by nature of being single-purpose emulators. The condition by which the C64 title was finally approved was the removal of the BASIC programming language (though ironically it’s still shown in screen shots, even on the App Store). Since only sanctioned programs can be installed and run from within the application, no user-alterable code is present.
The C64 emulator is neat enough in itself, but the really encouraging news here is that a precedent has been set; the business model may open the floodgates for developers to bring more classic gaming titles to the iPhone platform. So download that SDK and get hacking!

Update: The iPhone Blog
has a simple work-around
for accessing BASIC!
Update 2:
App pulled, no surprise. If you jumped on the opportunity while it was available, [George’s] comment might be of interest.

Remove the following lines:initialStatethe line that comes after itThose lines are not needed as they are more like a memory dump of the current game state. They will eventually produce a faster load time.Start C64 and voila your game should show up there.It looks like Apple has gotten wind of the BASIC hack and removed it from the store. Pity.

Reader [unangst] pointed out to us an article in the
U.K.’s Daily Mail
, where a teenager from Nepal had managed to create a 9v, 18W solar panel using human hair rather than the usual
semiconductors
(usually
crystalline-silicon
). The complex silicon in solar panels are what keep the prices out of reach of developing nations, and while there are
a number
of
new technologies
that are
helping bring down the cost
, [Karki] managed to make his solar panel for only £23 (roughly $38). He also claims that when mass produced the price could drop substantially down to under $10 a panel, which would shatter
the $1/watt sweet spot
.
The
melanin
in hair acts as an organic-semiconductor, and while the hair does not have the longevity that silicon panels have (months rather than years), these panels can be made cheaply and serviced with little to no complex knowledge. Using melanin as an organic semiconductor seems to be a newer idea, because information seems hard to come by, but we managed to find a research paper from 2007 that explored the energy absorption attributes of melanin, as well as some good background info for the science types.
Research Paper
(Warning: PDF)
So, Hack a Day readers, which one of you is going to make your home-brew solar panels first? Let us know when you do.
Thanks [unangst].

[Ryan] posted a writeup on
developing extensions for Google Chrome
. The extension system utilizes HTML with a JavaScript API which is still
sparsely documented
. After taking us through his twitter bar extension project, he concludes that the Chrome extensions are not nearly as versatile as
what we’re used to seeing with Firefox
. That being said, this is a move in the right direction for the young browser.

Monome Mainstream: Performance On Letterman

The monome was spotted being used in a
performance by Imogen Heap on Late Night with David Letterman
. Imogen uses the
monome 256 model
connected to a laptop sitting on the piano. In her performance she uses a combination of live samples and pre-recorded loops proving how great this product is in the hands of an accomplished artist.
Although not identified by name (or function), Letterman does notice the monome at the end of the performance. To see this kind of exposure for an innovative open source product is wonderful. Check out the Letterman clip as well as a monome bonus after the break.
[youtube=http://www.youtube.com/watch?v=54X7t8bDq_4]
[vimeo=http://vimeo.com/6255134]
This bonus video features a monome that sequences not just audio clips, but video as well. This way you can get a live video perfomance at the same time. [
Eliot
] ran across it a couple of weeks ago and mentioned that it reminds him of the
Amateur – Lasse Gjertsen
video. We agree and think that the monome is perfect for making this kind of product.

[Jared] sent us a feature he posted involving
time-lapse photography and an LED
. Using a custom built aparatus an LED is moved on two axis’ during a long exposure of around thirty seconds. The frame is wood and PVC with two gearhead motors powered by AA batteries to provide the locomotion. The LED is powered by a 3v button cell and automatically transitions through different colors.

Digital Camera LCD Replacement

Turning on your camera to this kind of black blotch will ruin your day. Cracked LCD screens have got to be the biggest digital camera killer out there. Although you can still take pictures with it, a non-functioning screen makes it difficult if not impossible to change settings and take decent photos.
[myles_h] has document the process of
replacing a broken screen in his digital camera
. As professional repair usually costs more than a brand new camera you’ll want to do this yourself. New screens can be purchased online, but we’ve also considered buying the same model of camera from ebay (screen intact but broken in a different way). This model, a
Sony Cybershot DSC-W50
, has fairly easy access to the LCD and its connection to the logic board. Before buying parts, you may want to
investigate how much disassembly your camera will require
.

This video of
littledog doing some terrain navigaion excersizes
is just hilarious. We really don’t have any technological updates since
last time we mentioned him
, but you should watch the video anyway. [Evan] at botjunkie pointed out how tired littledog must be to absolutely collapse at the end of each run. We started out thinking that his comment was humorous, but the bot is obviously going into a tidy configuration for carrying. As we watched, we saw that [Evan] seemed very correct. Littlebot completely collapses at the end of each run, toward the end of the video, it doesn’t even bother to fold up nicely, sprawling out in a very lifelike pose of utter exhaustion. We don’t know if this is intentional, but we think it should be.

[David] had an Arduino in search of a project. He decided to make an
Arduino powered iPod remote control
using an ipod connector breakout board and a 3.3v to 5v level converter (both from SparkFun). The circuit was built on a mini breadboard, controlled by an
Arduino Mini
, and housed in an Altoids tin. To talk to the iPod the
Apple Accessory Protocol
is used. With driving in mind [David] connected a
Staples Easy Button
as the play/pause button. This is a good example of how to interface Arduino with iPod. Using
his example code
we’d like to see more people working on homemade iPod accessories.

Apple Gives C64 Emulator The Boot

After making it to the top 20 in most regions, Apple has removed the
c64 emulator for the iPhone
from the App Store. Apparently the thorough app review process didn’t discover that the BASIC system had not been removed from the app, but was instead merely hidden.
Another revision of the emulator has been submitted for review but how long will that take? What is the review process for if they’re not looking deep enough to find specific functions they don’t want an app to have? Approving apps and pulling them a few days later is
another Hot Coffee waiting to happen
.

My theory: Apple is reaping the benefits of a software monopoly on their own hardware for now, but they are aware that this is not a sustainable situation. Sooner or later there’s going to be a competing device with really good support of Flash or something like it, allowing people to write and share apps without any manufacturer’s say-so, and Apple will have to follow suit.",

Hot on the heels of the
aluminum dock
and the
Lego camera mount
, [Steve] sent in his
iPhone/iPod Touch dock made out of Lego bricks
. It’s very stylish with a black and grey theme but we think the function makes this DIY spectacular. In the design [Steve] has included the ability to rotate the cradle so that the iPhone can be presented either vertically or horizontally. A step-by-step guide is not yet available but resourceful Lego lovers should be able to
build this using his flickr set

Trim The Fat From Gmail

Google’s Gmail is a highly viable option for email. With numerous features and options like widgets, a task list, labels, and chat, Gmail has a slight tendency to get overwhelming and might force us to loose focus on what it is really all about: email.
What can make Gmail better? For starters, how about no ads; they are cluttering and distracting. What about getting rid of the widgets and unnecessary features like labels and chat that we think are supposed to make us more productive but really only make us lose our focus to send, read and reply to email? Nobody knows Zen better than [Leo] at Zen Habits. We weren’t surprised that he and his friends (with Firefox and Greasemonkey) have found a way to
trim all the unnecessary elements from Gmail
and make it into an email powerhouse that focuses on a basic productive email client. The minimalist inbox for Gmail consists of Greasemonkey scripts for:
Removing gadgets
Hiding labels, chat and footer
Removing ads
Removing stars
Getting rid of the Gmail logo and searchbar
Removing menu navigation bar
Cleaning up and removing unnecessary buttons
To get started focusing on email, and only email, head on over to ZenHabits for a list of associated scripts and what exactly they can do to help you on your road to
the minimalist Gmail

Create A Temporary Phone Number With Inumbr

Maybe you don’t want that one person that has barged into your life to know your private phone number? Could be a salesperson or a co-worker who you aren’t that impressed with, but have to get in contact with. Check out
inumbr
.
inumbr
is a free online service that gives US users the ability to set up a unique phone number, have it forwarded to any number within the US and then have it set to expire without a trace when finished with it. The unique inumbr’s are never reused, and can be extended if longer terms are required. Users choose from a list of 22 area codes from major US cities like Chicago, Los Angeles and New York, select an expiry date and set a number that it should be forwarded to. When the term is up, the number is expired from the system, and never used again for any other user. If you wish to use the number at a later date, you can log into the inumbr system and reactivate it.
As we are becoming more and more mobile and security conscious, the desire for these types of services grows. A phone number can now be given out at will, with security and privacy remaining intact.
Google Voice
is a major player in this arena. A somewhat similar service, they allow for a unique number with voice mail to forward to other numbers at will, creating a masked or unidentified private number that can be used to give out to 3rd parties. inumbr makes this process simpler with the ability to cut off and reactivate numbers as desired.

We have a paid product called “numbr.com” and we don’t spend a dime advertising our services yet we get plenty of leads in our inbox due to inumbr popularity. I think its a fine business decision to continue to keep inumbr free while generating revenue from a paid product.For the skeptics, I don’t mind charging them if that would help them think its any better product.Feel free to contact me at [info] at [numbr] [dot] [com] if you have any question.I sincerely appreciate a post on HackADay about us.",

Life Size Animatronic Wolf Tail

We’re not 100% sure the usefulness of this hack, but it is extremely interesting regardless and will probably make a lot of
furries
happy.
WolfTronix
presents their method for creating a realistic
animatronic wolf tail
. It uses an Atmel MCU controlling two servos alongside a mess of
Klixx toys
and paper clips to produce a nice wag motion.
The guide
is extremely detailed and looks to be fun, so long as you don’t mind the monotonous task of shaving off potentially hundreds of ‘nubs’ as they call them. Either way, you’ll definitely have the best (and only…) tail on the block.
Thanks [J. Peterson]

The parts cost you all of fifteen bucks and (without any specialised tools) a few hours of your time.Instructable forthcoming.In response to muscle wire comments: That material works on the premise of heating metal through conductance, so unless you plan to keep your butt plugged in to a power socket, prepare to be disappointed with the extremely short battery life. If using a sensible structure, it doesn’t matter how close or far away from the ‘tail’ the servo is located, so you can really do anything you like to try and dampen the sound it’s gearset makes.",

Windows 7 And Vista Crash Via SMB Exploit

[Laurent Gaffié] has discovered an
exploit that affects Windows Vista, Windows 7
, and possibly Windows Server 2008 (unconfirmed). This method attacks via the NEGOTIATE PROTOCOL REQUEST which is the first SMB query sent. The vulnerability is present only on Windows versions that include
Server Message Block 2.0
and have the protocol enabled. A successful attack requires no local access to the machine and results in a
Blue Screen of Death
.
[Laurent] has a proof of concept available with his writeup in the form of a python script (please,
white hat
use only). There is no patch for this vulnerability but disabling the SMB protocol will protect your system until one is available.
Update:
According to the
Microsoft advisory
this vulnerability could lead to code execution, making it a bit worse than we thought. On the bright side, they claim that the final version of Windows 7 is not open to this attack, only Windows Vista and Windows Server 2008.

I am on an Eee that is a couple years old, running 9.04. It is stable enough for what I do with it (take notes) but it isn’t great. It works beautifully on my older Dell Latitude though.It is ready for a lot of people on the desktop, but you need to do your research before posing it as the answer to life, the universe, and everything. It will get there, but it is going to take some time.[/offtopic]I agree with full disclosure. I honestly don’t see how anyone can sympathize with such an excruciatingly slow-to-react company.",

Hand Of Man Mechanical Claw

[Christian Ristow], a former Muppet creator, has created a much larger puppet that has caught the attention of
Popular Mechanics
. His
Hand of Man
is a 27 foot long remote control mechanical claw. Powered by a 90 hp diesel engine, the
hydraulic system
can be controlled by a glove worn by the operator. This started as a demonstration for a robotics fair, but has recently made appearances at
Burning Man
,
Maker Faire
, and had the Grand Champions seat of Popular Mechanic’s Backyard Geniuses Award. While not as practical as
some
robotic human
augmentations, it can crush a car. [Christian] is even allowing anyone who is interested at these events to pick things up and crush them at their own whim.
Various promo videos after the jump.

You are the people I built this for.To those of you who don’t get it, or can’t fathom why anyone would build something like this, which is quite obviously intended for entertainment, I don’t quite know what to say other than that you should probably get out more.And to you, Drone, I can say the following: I know a bit about mechanical and control systems engineering, certainly more than most folks who never studied it. And I am willing to actually DO quite a lot with what little I do know. Believe me, I would LOVE to put proportional controls and feedback on this thing, but do you have any idea how expensive that is? I received a generous grant from Burning Man to build the HAND, but in the end it only covered about half of the expense. As a result of this labor of love, I am now more in debt than I have ever been in my life. If one were to very optimistically estimate the cost of converting ONE hydraulic circuit to proportional, with the valve, driver card, and feedback system, at $750, then the HAND, with 10 circuits, would cost $7500. Try living as a broke artist for 20 years and see how feasible that is.It’s apparently easy to criticize. Maybe a bit harder to think first.Once again, thanks very much to all of you who give positive feedback. Your comments, and the smiles on the faces of the people who actually operate the HAND, make it worth it.",

Aluminum IPhone Dock

Last week we mentioned an article to
cover up
that ugly iPod dock; [Jozerworx] did one better by creating his own
iPhone dock
entirely. He had access to a machine shop where he combined some spare aluminum with an existing iPhone connection cable, but mentions the dock could probably be created with basic hand tools and a power drill. The design is quite minimalist and we would go as far as to say it has that
shiny-and-made-by-apple-so-I-have-to-buy-one
look. Alternatively, frosted acrylic with some leds would probably look pretty cool too, maybe it would blink whenever there is activity. What kind of dock would you hack?

September 5th marks the fifth anniversary of Hack a Day. We hope you’ve had as much fun hacking, reading, and sending us stories as we’ve had sharing them with everyone.
Whether you
destroyed your hard drives
or
built your own web server
we tried to keep things interesting over the past year. It was easy at times because of
cool parking meter hacks
, great advances in the world of
hackintosh
, and
steam powered pleasure devices
. But we couldn’t have done any of it without you. So
keep reading
, don’t forget to
send us your hacks
, and we’ll serve up the latest and juciest as we find it. We thought about putting up a list of the best hacks we’ve covered over the last five years. We’d rather hear what you think, so please leave a comment to let us know what your favorites have been.

Firefox CSS Hack: Change Navigation Icons
|
Mike Szczys
|
[
"firefox hacks"
] |
[
"classic.jar",
"css",
"firefox",
"home",
"icon"
] |
Why settle for the standard home icon on your browser? If your home button brings you to
hackaday.com
, why not make the icon reflect that destination? This hack is quick and simple. We’ll take you through it using Firefox 3 and the default theme with standard sized icons.
We start by using our favorite
graphics program to make an icon
that is 24×24 pixels, and then saved is as a PNG file without compression.
To use the new image as a home icon, we edited a
Cascading Style Sheet
which is stored in the file
classic.jar
. On Ubuntu 9.04, this was found in
/usr/lib/firefox-3.0.13/chrome/
but
the file will be located elsewhere
on other operating systems. We made a backup of
classic.jar
and then unzipped the contents (
JARs
are basically the same as zip files).
In the unzipped archive, we navigated to the folder
/skin/classic/browser/
and opened
browser.css
using a text editor. This is where the magic happens and although we only changed the home button icon, there’s a lot more possibilities you should look into. We changed the
#home-button
entry so that the image URL pointed to our new file using the file:/// format. Here’s what ours looked like after the change:
#home-button {
list-style-image: url("file:///path_to_our_icon/hackaday-icon.png");
}
We saved this file, then zipped up the file structure back into a file called
classic.jar
and copied it to the same location we originally found it. A quick restart of Firefox showed the new icon. Let us know your other Firefox tweaks in the comments!
Update:
[Colby] pointed out that this type of CSS change should be made in the “userChrome.css” file. He’s right and here’s how:
Find your user profile directory
and go to the “chrome” sub-directory inside of it. Create the file “userChrome.css”; there may already be an example file that you can just rename. The important bit of this CSS file is the namespace line that tells Firefox how to use it. Here is what ours looks like:
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */
#home-button {
list-style-image: url("file:///path_to_our_icon/hackaday-icon.png") !important;
}
In order to get Firefox to listen to our new icon we had to had the “!important” keyword. Now just restart firefox and bask in the glory of your new home icon.

Open Source Digital Camera
|
Mike Szczys

[
"digital cameras hacks"
] |
[
"camera",
"frankencamera",
"open source",
"SLR",
"stanford"
] |
Those brainy folks over at Stanford are
working on an open source digital camera
. This is an effort to advance what they call “computational photography”. Basically they’re looking to combine some of the functionality of
Photoshop
or
Gimp
right into the camera. One example they discuss is utilizing an algorithm to even out the light levels from one side of the picture to the other. Another trick they’ve already accomplished in the lab is increasing the resolution of full motion video. They take a full resolution photo once every few frames and use the computing power of the camera to incorporate that information into the low-res frames around it.
We like the idea of being able to get at the firmware that runs on our digital cameras. Going with open source would certainly provide that access, but cost will be an issue. The Stanford team hopes to produce a model of what they now call Frankencamera that sells for “less than $1000”.

[Tixlegeek] used a Motorola 68HC705J1 development board to remotely
control his home
through his cellphone. The video above, as well as [Tixlegeek]’s website, is in French, though the video has been captioned. The development board (called the
ERMES125
) is controlled by a PIC externally. It has an array of LEDs, and apperantly a few high voltage relays. The PIC is connected to a laptop through a serial interface. The laptop is running a small web server, which uses
CGI
to control the PIC from a webpage. This system allows [Tixlegeek] to log onto the webpage from his web enabled phone, click a few buttons, and have appliances turn on or off through relays controlled by
the PIC
(via serial signals from the laptop).
