Ergonomic Vertical Mouse
|
Eliot

[
"Peripherals Hacks"
] |
[] |
I love waking up and finding a great project from a reader like this
ergonomic mouse
(
cache
). As you can see from the picture, the centerpiece is the massive scroll wheel made from a VCR head. He credits
jpaturzo for the idea
. The inertia of the wheel gives a lot better sense of how fast you are progressing through a document than methods like auto-scroll. The mouse is assumed to be more ergonomic because it keeps the bones in your forearm in line. The hand rest on the mouse is formed from
Shapelock
.

(but I suppose most of the cuts I got from handleing VCR heads didnt hurt, but my hands sure did look narly when they would get dirt in those cuts!) but I suppose its not nearly as sharp and cut inducing as a lot of the other parts on that mouse!whats so ergonomic about something that is going to cut you.but it looks way cool, if you like that future made of junk look if only it was a little dirtier, definitely a candidate for the post apocalyptic world of road warrior!",

Major movements are accomplished with movement of the wrist and maybe arm, but the fine positional detail is accomplished using your fingers with your wrist planted in the table.Now try the same thing but instead rest the side of your palm on the top of your mouse. Notice you loose that find control because now you can’t use your fingers for small movements. You now have to use your shoulder and elbow to control even the fine movements of your mouse as even your wrist has little control.",

They also moved a lot further before making contact. In short, higher finger strain and no tactile feedback.jpaturzo – Once again, seriously, thank you for the inspiration on this project.",

Thermaltake Mini Fridge
|
Eliot
|
[
"home entertainment hacks"
] |
[] |
[Jared Bouck] has posted the latest project at Inventgeek:
Thermaltake minifridge
. Jared isn’t a big fan of the cost/reliability trade-off that comes with most overclocking projects so he decided to take on an entirely different cooling project. He found this Thermaltake case that resembled a refrigerator and took it the rest of the way. The cooling components came out of two 65W peltier camping coolers. After gutting the case, he mounted the power supply so that the intake and exhaust are external to the case. The peltier coolers were wired directly to the PS and the entire case was lined with foam. The last step was to add plexiglass ramps for the cans.

Fan Controller
|
Eliot
|
[
"computer hacks"
] |
[] |
Unhappy with commercial fan controllers Jos van Eijndhoven decided to
build his own
. The circuit supports three LM60 temperature sensors with pots to adjust the turn on temp. A PIC 16F676 microcontroller reads the temps and controls three groups of fans. A potentiometer is also supplied to control the minimum fan speed. To prevent oscillation the fan speed is reduced slowly in response to temperature drop.

In summer, an actual AC unit has to be used instead.With this, I could use a relay on it to turn on the AC when needed,or the fans for intake to the room and output based on a variety of factors. For example, if the room is too warm and outside is cool, pump warm air out. If the room is warm, the outside is below freezing, pump the warm air into the rest of the house or the garage to make use of that heat. If its too warm outside to cool the room, kick on the AC unit.

PI control changes the output depending on the error and the integral of the error. This has stability problems also, but will always reach the target. PID control has a derivative component, so the output changes relative to the rate of change of input (thus if you’re approaching the target temperature quickly, this will slow you down). It’s a lot more complex than that (google Control Theory, Root Locus, s-plane). Putting digital PID control would be easy though, now you’re using a micro controller already.(just an idea :)",

Barcode Scanner Based Line Follower
|
Eliot

[
"Robots Hacks"
] |
[] |
Brody thought it was high time we featured another robot project and directed us to his site:
bfrdesign.com
. For his
line follower bot
he used an old barcode scanner he found cheap at a junk shop. The scanner has a 2088 pixel ccd linear image sensor. Several red LEDs are used to illuminate the image and the data is fed to an ATmega8. The wheels are then driven using two Sanwa servos modified for continuous rotation. He’s got a couple other projects on the site and I’m sure we’ll see more in the future.

Touch Probe For 3D Scanning
|
Eliot
|
[
"cnc hacks",
"Misc Hacks"
] |
[] |
Graham calls this
touch probe
his first useful milling project. He had already built the CNC mill and once he built this probe on the mill he essentially had a 3D scanner. The central hub is supported by three shafts spaced evenly around its axis. These shafts each rest on a pair of ball bearings to make a complete circuit. If the probe bumps into anything, one of the shafts will lift, breaking the circuit.
TurboCNC
has a built in routine for scanning with a touch probe. The program generates a point file which Graham pulled into
Rhino
for modeling. His example application was cloning a model airplane prop that had gone out of production. The TurboCNC routine isn’t very quick since the probe always returns to the same height so he’s coding a faster algorithm. This type of touch based scanning was also employed in agiecco’s
LEGO 3D scanner
.

Phase Change Cooling System
|
Eliot
|
[
"computer hacks"
] |
[] |
Chris Morrell has an impressive write up on all the ins and outs of
building a phase change cooling system
. Vapor refrigeration moves heat from one area to another by changing the phase of the working fluid. Chris used propane as the working fluid in his system. He’s got instructions covering all of the work involved from brazing the copper tubes, to building and lapping the evaporator blocks, to the final tuning. With no load it’s can hit -45DegC.
This story reminded me to check back on
extremecorvette’s cascading cooler
from last fall. He started receiving parts last month for a brand new design. I can’t wait to see how that turns out.

I’m not usually eye-to-eye with Greenpeace, but here’s a bit more:[hackaday does not trust me with blockquote, bold or italics]Hydrocarbons are flammable. However, their flammability can be easily mitigated through adequate safety measures in production and product design. The content of propane or butane in a domestic ‘Greenfreeze’ refrigerator equals roughly the content of two cigarette lighters. The risk of explosion is minimal: it takes between 17 g/cubic meter and 39 g/cubic meter to create an explosive mixture. Therefore, if the refrigerant were to leak outside the refrigerator, an explosion would be nearly impossible.[/hackaday does not trust me with blockquote, bold or italics]While many parts of the world either were grandfathered in to being able to make freon, or are using more efficient hydrocarbon refrigerants, there’s been a heaping helping of FUD (http://en.wikipedia.org/wiki/FUD) here in the USA against it for some reason.",

$20 Fisheye Digital Camera
|
Eliot

[
"digital cameras hacks"
] |
[] |
I know the camera pictured looks kind of wonky, “They just glued a peephole to a digicam, right?” The
fisheye camera guide from Aggregate.org
goes much further than that. They’ve tried out the $4 peephole lens on almost every camera in the office and have built dedicated ones using $15 pen cameras. I don’t plan on building one of these, but I did find their guide for removing “dark noise” from images really interesting. Sensor noise can be fairly consistent from shot to shot. So with some smart subtraction of a black frame from an image you can remove noise without blurring the image. They have information on masking and projection conversion as well.

I use one on my a510 that I got off ebay (along with the adapter tube so my camera can accept 52mm threaded lenses) and it works great for full-frame.

Xbox 360 Water Cooling Tutorial
|
Eliot
|
[
"Xbox Hacks"
] |
[] |
One of the most amazing things about the Xbox 360 isn’t the graphics or the high price; it’s how much heat the thing puts out. Hot air pours out of the machine and I’ve often considered turning mine into and Easy-Bake convection oven. People have been modifying the boxes since their initial release and xboxexpert, on
xbox-scene
, decided to put together a guide to help out anyone seeking to
watercool their Xbox 360
. From the text it sounds like he didn’t even play the thing once he got it from the store, the first thing he did was pull it apart. His setup uses Coolance GPU water blocks and a Thermaltake cooling system powered from the DVD drive 12V line.

I have an Elite now, but as soon as it’s out of warranty I’m going to water cool it, cause there’s no sense in the inadequate cooling it has to begin with. I’ve watercooled 2 of my 3 pc’s, and would watercool the 360 right now if it didn’t void my warranty. And seriously unless the 360 is going to stay put, then leave it as stock cooling. IMO if you’re moving your 360 around all the time, then your just asking for problems, even with stock cooling. I clean out my pc’s about every 6 mo’s, and they don’t get anywhere near the runtime that my 360 gets, and they’re absolutly caked with dust before I clean them. any heatsink should be cleaned frequently, and if it’s external, you can just use some compressed air, and never open the dang thing again.",

Canon 300D Mod For Astrophotography And IR Imaging

"digital cameras hacks"
] |
[] |
[Jan-Erik Skata] recently had to
perform surgery on his Canon 300D
since the secondary mirror would not raise up (and if manually locked wouldn’t autofocus). His repair guide is good; you may remember his
focus screen replacement
. The thing I found really interesting was the site he referenced for his disassembly:
Gary Honis’s Canon Digital Rebel (300D) Modification
. Gary removes the IR cut glass from inside the camera and replaces it with a piece of clear glass. He then shows how to setup color correction and confirm that autofocus is still working correctly. He’s even got a mockup for
how to add peltier cooling to the CMOS chip
.

I had to buy a main base plate assy. for $30 but it was still a cheaper alternative. Anyway, thanks. You might want to mention how to get out those two hidden screws that you must access from the rear of the camera by removing that black spacer by the memory card slot. I did some head-scratching on that part. Take care. Thanks again. Let’s keep our money out of greedy manufacturers hands!",

PIC Programmer Built From Broken Monitor
|
Eliot

[
"Misc Hacks"
] |
[] |
Khoa wanted to give a friend a
microcontroller programmer
(
cache
), but didn’t want to spend the money. He found almost every part he needed inside of a broken monitor he had in the closet. The only parts he had to provide were the perf board and the serial port. Even the socket was in the monitor. It was too wide, but he just cut out the center spar and made the socket narrower.

Even a beginner repair-person could do that with ease in a matter of minutes...To follow your analogy, it's like taking the tire off a junker to make a swing. the car is already \"dead\", and the changes being made to it could be easily reversed.In regards to the landfill bit, do you have any suggestions on how a monitor wouldn't end up there? Even if it were repaired and put to good use, it will eventually become irreparably damaged and get tossed. I think this simple reuse of materials is really our best option. Sure this project only used a small fraction of the monitor, but I hardly think khoa is done with it yet!This is a nice hack, khoa, and is exactly what hack-a-day is all about: turning \"worthless\" things into objects of (geeky) art and utility.",

If he had, say, made a radio out of it or something that used more than the most miniscule of parts. If he continues gutting it for parts, okay. But, i was referring to that, in my own experiences trying to replair monitors (not that I’ve had much success, but still), it’s usually a single large part that dies, such as the flyback transformer, not the resistors, transistors, etc., but once your remove 15 random transistors, it makes it much harder to repair, esp. without a full schematic.Anyway, i’m 100% for the “make a pic programmer” part, just somewhat opposed to “tear apart a much larger thing to get $15 worth of random parts” aspect.The mention of this ‘hack’ being below expected quality was that it could be boiled down to “tear apart major electronic item to make $15 minor electronic item (using $10 of extra parts!)”, which, while generally applicable to computers, monitors, vcrs, etc, etc, is only a ‘hack’ because someone took an axe to a monitor. He just referenced a already available schematic, after all.Avoiding landfills is a difficult subject. I myself have a shelf of 6 or so old (not dead though, so I can’t make pic programmers yet!) monitors that I’m not sure what to do with. I guess I could make a cool LED-flasher.

They show up as a JDM programmer.http://www.ic-prog.com/http://www.qsl.net/dl4yhf/winpicpr.htmlAs for the broken monitor comments, jason, you’re right, it was a useless OLDDDDD monitor, images were faded and burned onto the screen. it was broken to the point that repairing it is not feasible because it was junk that my friend took from a computer salvage business (we attempted to repair it a while back for just a text display, couldn’t, so it ended up in my closet incase i needed it in the future). i’ve fixed plenty of motherboards and monitors from bad components before and i didn’t think the effort of fixing this one was worth the time and money. i’m planning on using a lot more of the components in the monitor’s circuit board later on as well, plenty of nice parts, like flyback transformers, tons of diodes and transistors and useful pots. by the time i’m done scouring it for parts, there will be only the crt and pc board left.I know, some of you may not really consider this a “hack,” thats cool too, just thought you guys would like to know that your scrap parts are still useful for practical purposes.

12″ RC Ornithopter

There was a little interest in Graham’s
3D scanning probe
, but this is what he is normally using his tiny CNC machine for: manufacturing components for a
tiny RC ornithopter
. The scale of this thing is amazing. From the tiny gear train to the 0.5mm carbon spars the frame is constructed from. The rudder control only weighs one gram and the entire device comes in at 17 grams.

MF2006: Monome

The people from the
Monome
project are out in full force at the Faire. They’ve got five of the 8×8 pads hooked up for people to play with. The first two pictured above actually work together as a 16 step loop system. There’s also one hooked up as a mixer and another as a drum machine. The fifth one is showing pixelated video from an iSight. The box is really well built. The $500 price point has shocked a lot of people, but it’s really unavoidable since they’re only doing a 200 device run. Something I hadn’t realized before is that the buttons are unique to the device, not off the shelf parts. The button is really a rubber cap that sits over the LED and has a conductive ring at the base. I hope they post a schematic for their 8×8 matrix controller so that anyone could build one. Here are a few more pictures:

Repeat settings, etc can be controlled in software. As a bonus, it also has 3 outputs (Scroll lock, key lock and num lock). As for the leds, 35 line output led drivers can be had for around US$2.80 each. One of these with line scanning can easily drive an 8×8 matrix (in fact one can drive up to a 16×16 matrix).

Iridium Flare Tracker
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Iridium is a constellation of 66 communication satellites. Each one features 3 large polished antennas. The reflection of sunlight off of these panels causes brilliant flashes of light. Since the satellite’s orbit is known the time and location of these flares can be calculated ahead of time.
C.L.I.V.E.
is a project designed for Burning Man to assist in observing these flares. It has a DPSS laser mounted to a turntable that automatically points at the location of the next flare. A large clock counts down the time till the event. Everything is controlled by an
Xport 2.0
FPGA development board for the Game Boy Advance. All power is provided by a solar array and wind turbines.

"Portable Audio Hacks"

I was stumbling through
HeadWize
‘s project archive the other day when I came across Steve Connor’s
Poor Man’s Surround Headphones
. He used a pair of Sony MDR-CD60 for the base and added three pairs of ear buds. One pair is used for the front channel and two for the rears. The rears have their own amp with the bass turned up to increase the separation. He used a Sound Blaster Live! card for the source. If you are interested in amplifiers and other sound projects, you should definitely have a look at
HeadWize

DD-WRT Running On WRT54G Version 5
|
Eliot
|
[
"Wireless Hacks"
] |
[] |
With version 5 of the WRT54G, Linksys decided to dump Linux and start using VxWorks. This made buying a WRT a gamble if you wanted one with Linux. DD-WRT recently released a
micro version that supports version 5
. You’ll need a
JTAG cable
to install it since very little is known about VxWorks bootloader. Even with this new firmware it’s hard to ignore that the router is underpowered and you’d be better off with something else.

A build without such things could be even smaller. There is no reason the V5 couldn’t run Linux and have the 2/8 configuration. DD-WRT proved this.My guess is that it isn’t about preventing hacks, or even the cost of chips, but maintaining the Linux branch for the routers. The official firmware was always behind (i.e. security patches not applied) main tree releases and that paying VxWorks to maintain the OS is probably cheaper than doing it in house.

CarPC Shutdown Controller
|
Eliot

[
"Transportation Hacks"

[] |
I’m sure most people that have built a CarPC are already familiar with
shutdown controllers
, but I think this hack is pretty clever. Computers don’t like being turned off suddenly so you need to figure out how to power down the PC safely. This circuit has a serial connector and appears to XP as a generic UPS. When the ignition is turned off it breaks the 5V line to COM pin 8. XP responds by hibernating. Once the computer shuts down the relay for the power inverter opens. When the ignition is switched on the inverter powers up and the computer turns on.

DC-DC is more expensive, you need the DC-DC converter itself, and you must build a computer with a relatively low power consumption. But, you’ll end up with a cleaner power supply (not that it matters to the carpc itself IMO as long as you are within tolerances). You also have more options as far as startup and shutdown controllers go.If you use a power inverter, you can use a standard PSU. This method does not cost as much, but it has a few drawbacks. It will most likely put feedback into the power system which you will hear in your audio. It is also not very efficient – you are going from AC-DC (car alternator to rectifier) back to AC (inverter) and then the PSU goes to DC. But, if you have an older computer that is power hungry – it can be a good compromise. — Why use an older computer? You really don’t need much computer power to run most functions.If I had the money to do it – I would be using the opus DC-DC PSU as mentioned in #13",

Boot Camp… I Give Up
|
Eliot

[
"Uncategorized"
] |
[] |
UPDATE:
I’ve solved my issues click the “
Continue reading
” link.
I’m sure you saw the news of Apple releasing the Windows bootloader
Boot Camp
yesterday. My current desktop machine is a Core Duo Mac mini so I figured I’d give it a shot (so I could run four
folding
threads, naturally). I downloaded the Boot Camp package and upgraded the mini’s firmware. The first thing the Boot Camp install assistant does is burn a driver disc for use after the XP install is complete. Once this is done it shrinks the HFS+ partition and creates an empty partition for Windows. It then asks you to insert the XP install disk (must have SP2). The Windows install proceeded normally and Windows booted. This is where my trouble began: the drivers didn’t apply cleanly. I could have retried but for one serious problem. To get the initial boot device selection screen to appear you have to hold down the “alt” key while the machine is starting. The only USB keyboard I have is a Gyration wireless one. The boot menu only showed up at best 1 in 10 attempts. Apple does provide software to choose which OS you want to boot by default, but since the Windows drivers didn’t install there was no guarantee I could flip the switch back to OS X once I was in XP. I decided the flaky “alt” key detection was probably my wireless keyboard not being fully initialized, so I made a late night run to the Megalomart to buy the cheapest wired USB keyboard they had. I plugged it in and tried to bring up the boot menu; it didn’t work a single time. So, my experiment is over for now since I don’t want to get trapped in XP. Hopefully they fix this public beta so that is has an actual boot menu, with a countdown, like
every other bootloader
. UNEASYsilence has a
video
of how this install should go.
UPDATE:
I found an Apple keyboard and now the “alt” key works every time. So with the confidence that I could always bring up the boot menu and return from XP, I proceeded with the XP boot. This time the drivers installed without a hitch. That includes the “startup disk” control panel. It wasn’t installed before which is why I needed reliable “alt” access to the boot menu. I doubt many people will find themselves in my situation, but having an Apple keyboard on hand is a good idea.
Now that I’ve got Windows going, anybody have a killer app for what XP can do on Apple hardware that OS X can’t (besides run Windows applications)? Here’s a few that I can think of: Update the firmware of a Windows format iPod (I kept it Windows format so I could read it on any computer), run native Folding@Home cores (no cores for Intel Macs yet only PPC on top of Rosetta), Bluetooth A2DP (OS X doesn’t support stereo Bluetooth headphones). Yes, I posted this from Windows.

It just goes to show, no matter how smart you are, not reading instructions can still look like a whiny noob :)",

There’s also, of course, no right button or, as far as I can tell, a way to easily simulate one (thought there was a usability option in windows for this, though.) there’s also an odd issue with the sound where audio outputs from speakers, audio-out, and the optical all at once and all the time, so no headphones overriding built-in speakers yet. Also, the touchpad seems a bit flaky and jittery, even with enhanced precission on.In the end, though, I can run all my games perfectly and can run Adobe CS2 apps at full speed, no slugging it out with Rosetta until CS3 hits (Rosetta is great and all, but for big apps it shows painfully.)

Mini-SD And RS-232 Board For Zipit Wireless Messenger

Eliot

[
"Wireless Hacks"

[] |
Tom Walsh has been hard at work building an
add on board for the Zipit Wireless Messenger
“IM Device for Teens”. The board adds a mini-SD card slot, RS-232 (using a mini-USB connector) and a power supply for an EL backlight. I’m impressed that he got everything to fit inside of the case, very slick. A year ago we covered
putting Linux on these devices
. Have any of you readers picked up one and what fun tricks can it do? I looked around and they still cost over $90. I should probably just resurrect my Zaurus and be happy

At the time I purchased mine, I believe most on ebay were running in the 80-90 dollar range, but as mentioned in other comments, the prices have fallen far far below that of late.Regarding the use of the zipit as a device monitor, Ken McGuire (along with zipitpet, the man behind much of the initial work hacking the device and writing of drivers), has been using a zipit for several months now as a weather station. IIRC, It records data from a device over rs232 and pushes the info via wifi to a server.Somewhat related (and quite interesting), this pagehttp://va3uxb.dynip.com/is being served off of a zipit with minihttpd. All in all, The zipit is fantastic as a tiny wireless ssh client and wifi auditing tool.For those who still wish to use IM, any irc client you can compile should work. With the help of naim’s author Dan Reed, I hacked naim into running nicely on the zipits screen. See the yahoo group for src and patches.At the moment, the zipit can be modified to have extra storage as mentioned, play audio both streaming and from storage, use irc/aim/etc clients, has ssh, wavemon, madplay, etc. The wireless chipset is amazingly strong for such a tiny device and the battery lasts a good 4-6 hours with continuous use. Recent developments include running nanoX, backlit screens, etc.Any interested parties should check out the following resources:-The Zipit devel group is an absolute must (covers hardware/software modifications both existing and ongoing. has photos, schematics, programs, sources, also has the OpenZipit distro for the zipit platform premade for anyone wishing to reflash the device):groups.yahoo.com/group/zipitwireless-The Elinux Zipit wiki (information repository and howtos for hardware/software modification, cross compiling, etc):http://www.elinux.org/wiki/ZipIt-Programs and linkshttp://www.santoni.ca/albert/zipit.html-NanoX compiled and patched for zipit: newstar.rinet.ru/~goga/zipit/nano-X/-hardware.slashdot.org/comments.pl?sid=156110&cid=13087583By all means, drop me an email atsteve@fugitivethought.comif you would like more information or assistance.",

[Ryan Walker] had recently constructed a 16 R/C servo controller board and needed a
platform to test it with
. He wired 6 cheap TS-53 servos from Tower Hobbies to the bottom of an empty box. He’s got push buttons on the top for direction control. It uses a PIC18F452 for processing and the board was routed on an LPKF circuit board mill. There are videos on his site, but try using these cached links first:

It also drills the holes with changeable drill bits. There are contour router bits to cut the perimeter of the board from the copper sheet. It is a slick setup but the copper is prone to corrosion and looks terrible once there are finger prints on it. This could be solved with a protective spray of some sort, but it is generally used more in a prototyping environment than long term use.",

Ugh, I didn’t expect this “sonic nuisance” meme to last past yesterday, but here we are with a different project from [jay]. ThinkGeek sells a device called the
Mind Molester
that emits a chirp every three minutes making it hard to find but frequent enough to drive you insane. Jay figures ThinkGeek’s markup was somewhere around 1250% and
decided to build his own
. The device uses a Picaxe microcontroller and emits four different sounds a random intervals.

It works because the output is attached to the negative lead of the buzzer and will be high for five minutes. Then it goes low and sinks the current for 150ms.With a speaker:http://img154.imageshack.us/img154/382/speaker4ld.gifThe chip on the right outputs a 3KHz square wave whenever the reset pin is high. When the reset is low, there is no output. You have to invert the output of the timer on the left, because it is not possible to have a duty cycle of less than 50% (meaning the low period is longer than the high) because that would require r1 to be negative.Of course, at such low frequencies, the timing is not very reliable.

Sonic Grenade

imakeprojects.com
started recently with the promise of delivering one project every two weeks. Yesterday was their second release:
sonic grenades
! They picked up a couple 110dB personal alarms at the Dollar Store and modified them. Now instead of going off immediately, there is a 5 second “fuse” indicated by a flashing LED; giving you plenty of time to lob it into your roommates space. After a minute of being active, the grenade will start chirping every 10 seconds until you replace the pin which should help you find it. There’s a video demo at the bottom of the page.

"content": "Pretty sweet. And the pic code looks easy enough to modify without knowing how to code it. Not only is it useful for this grenade, the code provides a way to create a cricket. (A cricket is basicly the last bit of the code that it chirps fast with a delay inbetween. Limit the volume a bit and change it from a 100 msecond chirp to maybe a 75 ms and the 10000ms delay to about a minute. Then turn it on and place it in someones room. It drives people crazy because it chirps and then stops, so it doesnt chirp long enough to track it right away. Hell, its a pic, so you could change the code to create one that changes the delay according to a light sensor or another input, or random number generating to pic a delay, making it near impossible to find) For example:http://home.wanadoo.nl/m.m.avos/c_cricket.htmAlso, you can add more then one in a grenade to make it annoying. My addition to the project would be adding another pierzo speaker and include a small increasing chirp (And increasing led) for the timer instead, much like what digital cameras use for a timer (Think 1 chirp/flash, 3 second delay, 2 chirps flash, 2 second deley, 3 chrip flash, trigger main alarm)",

Hack A Day Goes Autonomous

] |
After
declaring our independence
last fall, complete site autonomy seemed like the next logical step. Using some clever coding we have developed a system that will let Hack a Day run without any intervention. The first layer in this system is topic selection. All
tip line
submissions are sent through a series of filters. These look for keywords like “firmware”, “POV”, “microcontroller”, “video”, “linux”, “WRT”, “GPS”, “PCB”, “TLA”. Each submission is given a l33tness ranking based on these words and the best tip is immediately thrown away. The second highest link is then passed through our advanced anti-duping engine that confirms the link hasn’t been posted in the last week. The post text is generated using
Markov chains
in what top scientists suspect is a miracle. The story is then automatically cut and pasted into Digg without credit. To foster discussion the reader comments are automatically seeded with “first post” and “this is not a hack” on every post. This system is implemented using a large quantity of duct tape (code and literal) on our brand new Linksys WRT54G beowulf cluster. We hope this system serves you well. We’ve been working on an “auto-hacking robot” to generate how-tos as well, but on its test run it instinctively disassembled itself.

Reversing Extension Tube For Macro Photography
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Reversing the lens orientation is common practice in macro photography. To get even more magnification you can increase the distance between the film and lens by using an extension tube or bellows. [Kevin] built this
variable length extension tube
by modifying a bunch of cheap used filters. When I say “modify” I mean he “broke the glass out with a hammer”. The base of the extension tube is a body cap that has had the center removed. Glued on top of body cap is a filter ring with the male threads pointing forward to act as the reverse lens mount. You can add any number of additional rings to change the length. It’s very important to be thorough when cleaning your filter rings otherwise you might damage your camera internals.

[Laurens Tromp] stumbled upon this
LED lamp
project while looking for a datasheet. The lamp has two heads with 252 LEDs each. The individual heads have equal number of red, blue, green, yellow and white LEDs. At the base of the lamp is a touch pad that has a virtual slider for each individual color’s intensity. The heads can be controlled separately or together. The lamp can also be operated over ethernet since its controller is a RabbitCore RCM2200.
The only answer I can’t seem to find in the extensive documentation is
how much this milled aluminum monstrosity weighs:
110 pounds

If you didn’t catch NOVA’s coverage of the DARPA Grand Challenge on Tuesday, titled
The Great Robot Race
, it is now available online in chapter form
on the official site
. Autoblog has an
excellent synopsis
. If you want all of the video in one piece, you can
find it on Mininova
. I’m sure the episode will be replaying on PBS throughout the week.

That’s why I put the word “cheated” in quotes.But the point of this competition was to make a vehicle that could follow roads and go around obsticles. CMU’s vehicles had to do much less work to figure the route since they added thousands of waypoints. This was demonstrated when their laser unit got stuck turned to the side and the vehicle still finished the race. They had so many waypoints they didn’t need to do any scanning of the road to see where to drive. That wasn’t the point of this competition.And no, I don’t think the military would use satellite images to “determine better routes round a coordinate set” unless that was the only way this could be done. Stanley demonstrated that this wasn’t necessary. Ideally you want to be able to just give it a set of directions from a map and let it go.I also get really tired of people who say things like “you assume that they cheated maybe you should take on this task,” and other forms of the standard “if you can’t do better then shut up.” There is nothing in the electronics on these vehicles that I couldn’t have designed, but I’ll admit that my software programming skills probably aren’t up to the task. But just because I couldn’t do what they did doesn’t mean I don’t have the right to to criticize what they did.Now, since most of this sounds rather negative, I would like to say that this race was a great accomplishment by everyone who was involved, and all the entries were quite impressive. The military, and anyone else interested in autonomous driving, will learn a great amount of valuable knowledge about what to do and what not do do when designing systems of this type, which was the ulitmate goal of this exercise.

I’m glad stanley won, it approached the problem in the spirit of the competition.Yeah, the adding in of tons of waypoints was cheating in my opinion (not by the rules, just by the spirit of the competition). It probably took 60 man-hours to create all of those additional waypoints. It would take a human less than 5-hours to remote control it around the course.What’s the point of autonomy if in practice it takes a ton more effort to do anything?This is why I think the military preoccupation with autonomous robots is retarded. Sure, it saves lives to have robots do things. Why not make them remote control? still saves lives, and gives all of the good gamers of the world decent jobs.Yes, this would introduce strategies such as jamming the control signals, in which case autonomy might be necessary, however most of the time you could probably use remote control.@13 – this is why cmu cheated – their robot doesn’t really solve a problem. It would be easier just to remote control it, instead of devoting 60 hours of work creating waypoints.",

Considering the way the system works, these “thousands of waypoints” were not used to steer the vehicle, just to give it an idea of where to go.

Camera Adapter For Detecting Melanoma
|
Eliot

[
"digital cameras hacks"
] |
[] |
[MM] has built a simple
lighting adapter for analyzing skin lesions
. Different layers of the skin absorb different parts of the light spectrum. By shining those particular wave lengths on the skin you can get an image of the lesion in various layers. This camera adapter is designed for a Nikon Coolpix E3100 digital camera. The ring of LEDs contains blue, green, red, and IR. White is included as well for taking normal pictures. A polarized filter is used to cut down on light reflections from the skin surface. The device does have some calibration issues since it was soldered by hand, but the preliminary results look very promising.

"content": "Briefly,Biophotonics is the study of living things with light. The idea is to image the object without killing it (X-rays etc.) and without the instrument costing a fortune (NMR).Biooptics is the subfield which employs visible to near infrared light. This is because of the so-called “biological window” at these wavelengths. Visible light doesn’t hurt you, so your body doesn’t waste resources in blocking it as with ultra-violet etc. It is also easier to generate and work with.Have said that, the different structures and materials absorb/scatter light differently. This project deals only with the absorbtion aspect (he gives examples near the top regarding the chosen LED wavelengths). By using different wavelengths he is able to choose specific types of structures. You may find Alfano’s paper “Deep subsurface imaging in tissues using spectral and polarization filtering” useful (it is freely available on Optics Express).For those of you considering such a project I’d suggest three things:(a) consider using one of those little laser keychains. You can then use off-normal illumination to remove specular reflection at the skin surface(b) consider wetting the tissue and placing a sheet of plexiglass (or the equivalent) over the tissue, this will provide a better interface than the skin/air(c) consider making the final polarizer turnable. You can then take the CO and CR polarized images and generate the POL (co-cr/co+cr) image. This will tell you about the scattering within the tissue. Absorbtion information is nice, but you need scattering to get detailed results.For more info:Search for “Steven Jacques” he is very well known within the field and has a number of good papers. Alfano is on the other coast doing work with CCNY. Finally a shameless plug for my own paper in polarization imaging:“Expression of target optical properties in subsurface polarization-gated imaging” athttp://www.opticsexpress.org/abstract.cfm?id=84159",

"content": "There are a lot of projects going on to attempt to advance the medical field using optics. With current non-optic tests for malignant tumors, it can take 15 minutes for the doctors to decide if they should remove more skin (cut a little, test, cut a little, test). Imagine how much faster this whole process would go if you just turned on your cancer detecting headlamp. Another project under way is in trying to detect blood-sugar levels for diabetics. It would be some development indeed if diabetics didn’t have to draw blood to test this.On a side note… is #3 trying to say that lasers can cause skin cancer? Either that or he is talking about shining bright light on a tumor caused by light. The LEDs used are not in the UV spectrum so it doesn’t really matter either way.#4 it’s simpler than you’re probably making it out to be. How do you detect blue? Shine blue light on something. Detecting cancer is simply a matter of shining “cancer colored light” so to speak. That’s basically all that’s going on here, not to say this is a simple task by any means.",

[Chris Rybitski] didn’t really have any money to spend when the headunit in his car died. He did have a broken JVC CD player from a friend and
decided to convert that
into something hideous he could use in the car. The amplifier portion still worked, but the CD section didn’t. Unplugging the CD board kept the amp from functioning, so he cut off the bulky motors instead. The internal power for the player was already 12V so he powered it directly from the car. He added an old CDROM drive, made a wired remote for the controls and stuffed everything in an old Mac case. Once completed, he set it under the rear glass for everyone to admire.

(and I wouldnt run more than a hundred watts or so through it w/o pulling another thicker wire). For the people saying that they are getting peaks of up to 50v, I disagree, youre having problems. If you do have voltages that high, fix your regulator before you fry everything in your car.Anyway… Nice to see, Thought about doin something like this w/ an old dvd player years ago (before they were so common in cars)… sadly a CD player will run you about 30 bucks these days used.",

A few notes: they drop about .7 volts each (varies), so with two always working, your 12 to 14 volts DC going in comes out at about 10.6 to 12.6 volts DC (which is perfect for the amp). This would be true (and properly polarized!) no matter if it were DC or AC. Also, in the link I gave you, the arrows are confusing. They represent ELECTRON flow. dont look at them. Instead, look at the symbol for the diode. Its an triangle with a bar on it. Positive voltage goes in the direction the triangle points. when Positive voltage attempts to go backwards (reversing the leads), it hits the bar and is blocked.Great hack by the way. Too bad you cant play “oregon Trail” on it though ;)",

Go half way down to the part that says “Full wave Rectifier circuit (bridge design). Forget about the arrows on the drawing.Look at the Supply on the left (circle with a wave in it). Normally this is AC, but ASSUME that it is the car’s power supply (DC). Now, the first drawing with arrows on it shows what happens when the battery has the positive lead going into the top of the bridge. Notice the positive voltage goes through the diode on the right and comes out at the Positive pin of the bridge. The Black diodes are the active ones in this case (allowing voltage to pass), and the gray are inactive (blocking voltage from passing through).The Next drawing shows what happens when the battery has the positive on the bottom. Notice that the positive voltage would go up from the bottom through the right diode and end up at the same place.Positve will ALWAYS come out the right side of the bridge, and negative on the left, no matter which direction the battery is attached to the top and bottom.If that doesn’t clear it up for everyone, I give up ;)(I DO admit perhaps my first couple posts on the subject might not have been all that clear.)",

An alternator and regulator do not regulate voltage in the same way as normal integrated circuit regulators, such as the 7805 in this project. The way an alternator works is that the regulator changes the current through the field coils to change the amount of magnetism produced by those coils such that the armature generates the necessary voltage no matter what the engine speed or electrical load is. In an ideal world that is.But what actually happens is that those field coils have a lot of inductance. Inductance resists changes in current flow. Therefore you can’t change the field current instantly when a big load, such as the battery, is disconnected. There is a fraction of a second where even after the regulator has tried to reduce the current flow to the field coils the actual current doesn’t drop much. Durning this period you have way more field current than you need, so the voltage generated by the alternator shoots way up from where it is supposed to be.",

Maybe 50V is a bit high, but if the designer of your stereo had any clue what he was doing, it is designed to take voltage spikes into the 40 some volt range.And like I said twice before, it’s not just a faulty regulator that causes spikes. Spikes can come from disconecting the battery while the engine is running, charging the battery, jumpstarting the car or jumpstarting someone elses car, loose battery cables, loose ground straps, and a few other things I’m probably forgetting.",

Real commercial car stereos are designed to take voltage spikes in the 40 volt range.Your hacked up system isn’t designed to do that, but sometimes you might get away with it for a long time. Protection circuits aren’t needed until something goes wrong.So don’t be surprised if it quits working someday after you jumpstart someone’s car or a battery cable comes loose.But don’t worry about it either. This is a system you hacked together out of free parts. It’s OK if it isn’t designed perfectly. :) And even if it does break, you learned something in the process, and you’ll have an excuse to do it over again and fix the things you’ve learned how to do better the second time around.",

Computer Controlled Multiple Light Dimmer

[SeBsZ] built this
16 dimmable lights controller
based on his friend
Christian N?g’s
PC_DIMMER
project. The PC_DIMMER project supports up to 128 individual lamps with 255 steps each. The controller boards feature an Atmel ATTiny2313 microcontroller that controls 8 lamps. Sebsz built two boards for his project and has status indicators mounted on the side of the box. Everything is driven by Christian’s free software through a serial connection. SeBsZ warns that this is a 230V@50Hz design and you will need to modify it if you intend to use it in the US.

Firstly, the steps in some of the dimmers are few and far between, meaning a smooth fade turns into a mess. Also, the protocol doesent like handling data at very high speeds, with most software (i have found) there is no easy way to produce a “chase effect” and the minumum timing is something like 5 seconds between “cues”. I did use IBM’s “Homedirector” software to configure a simple chase but it would cause the machine running it to hang frequently. Lastly, most dimmer modules are not grounded and are rated for a max of 300 watts. (not very much) All in all, this looks like a promising project. While i went the route of #4, I may have to look into this project around X-mas Time. Or if anyone has links to open source X-10 software, i’d be willing to have a look.",

Fine, if you find something on ebay, go ahead and buy it, that isn’t the point of it. You are talking about a 69 dollar 4-channel dimmer? I don’t even want to know how much a 16-channel dimmer would cost.Secondly, all you people talking about X10 here, this isn’t about switching a light in my bedroom on or off, this is about creating huge lightshows that are in REAL TIME. X10 is extremely slow, and sometimes the signals aren’t even received and you have to resend them. This controller is instantaneous, you send a signal and immediately the controller will react and fade beautifully or will do anything you ask it to do.I am sad to hear that a lot of you think about this project in this way. If you think X10 is 10X better, yes maybe in your case when all you want to do is control your living room lights and you don’t want cables running to every light. This is different, and a lot of you didn’t get the point.#11 pretorious, no. You can change the transformer which will then give you 5V to run the boards on, which is fine. However, the controller uses something called zero-crossing to detect when to fire the optocouplers. In the USA, it is 60hz, in Europe – 50hz. It might work, but you definitely need to get a different firmware made for 50hz. You could ask Christian and he might be able to do it for you. Just go on the forum and ask your question in English, he will answer.SeBsZ-",

Email On The Cisco 7960

"Misc Hacks"

The Cisco Unified IP Phone 7960G is becoming fairly common in corporate environments. The phone has a built in XML browser for navigating menus. [Nick] decided to hack together a PHP application that will
let the phone display email messages in a POP3 account
. In its current form it works with most text-only messages, but limited filtering means it could fail on some.

How To Reverse Time

[
"Cellphone Hacks"

[] |
[moddy] sent in a couple of his projects that would probably be entertaining on a Sunday afternoon. The first one is how
to reverse the rotation of a battery powered travel clock
. It’s just a simple modification of the plate the coil is wrapped around. The second is adding
9V battery terminals to a cell phone
. Neither project is practical, but they’re still fun.

I didn’t manage to make the clock go backwards and anyway I don’t think it would have had sufficient torque.

$100 Hot Water Bottle Pendulum Rebreather
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Humans exhale a lot of oxygen along with their waste carbon dioxide. Instead of throwing out this oxygen, a rebreather uses a scrubber to remove the CO2 and replace it with pure oxygen from a bottle. Tom Rose built this
rebreather for $100
. When you exhale air passes through the scrubbing material and is stored in hot water bottle counterlung until you inhale. The system is only 15 pounds; a great savings compared to most dive equipment. You are definitely putting your life in your own hands so this should not be used without plenty of “couch-diving” tests. Tom has a ton of other
diving related projects
on his site.

They need to understand the dangers of scuba diving and why oxygen can be toxic.Diving is great fun. It is a good sport for geeks. There is the technical aspect of all the gear. And there is a great opportunity for discovery as you never know what you will find.",

All it takes is enough R&D and above water testing to be reliable. And at the very least have an alarm system, with another backup alarm system, to alert the diver to improper conditions so he can immediately surface. After all this system wasnt intended for deep submergence anyway.And even the author is making a heads up display to keep him updated to variables while hes under. or did you even read that far?one of the thing that makes this risky is that people may try to assemble a device with just whats in his description. in case you didnt notice he has left out and kept secret some important details to make this thing functional. that coupled with some scare propaganda to keep people from trying and figuring out the full plan because he knows that if people know his full design they could then go on to improve upon it faster and better than he ever could.*although to his credit im sure hes also got peoples safety in mind too*i agree that safety is important, but dont forget the fact that you could test indefinitely on dry land where the proper lifegiving air is only a masks pull away. for that matter, who says this would only be for aquatic use? firemen could shed many pounds of breathing equipment and be more effective in saving lives, in that last big coal mine accident, the rescue workers were afraid to go deep enough into the tunnel to rescue all those oxygen deprived workers due to the unsafe air. if they had these they could have promptly pushed ahead and no doubt saved some, most, or maybe even all of them. also possible emergency aircraft water-crash devices. you couldnt hang a shitload of scuba rigs around the aircraft but you could certainly outfit it with these compact lightweight lifesavers.thats not even going into the enormous military applications. the seals and sf use a heavy large cumbersome device called a draeger.if they had a 10 to 15 pound rebreathing rig then they could carry alot more other gear, not to mention the fact that it could be extremely covert. possibly concealable under a suit, or carried on an operators body along with his other regular dry-land assault gear. yes the possibilities for this tech are very awe inspiring indeed. one could escape from any persuers just by finding the nearest body of water. a real life aquaman.even though foreign intelligence services and our own uber-top secret weapons grade research facilities are no doubt all over this and haveprobably even perfected it by now, their *hacks*, although years and years ahead of us mere mortals in conventionally funded r&d labs,are and will remain highly classified. so, the first private individual or firm who perfects and patents this lightweight rebreather could potentially become *billionaires*.",

Hazardous waste sites, underground utility work, and confined space entry programs are other applications. These applications often require an second breathing option (typically an escape bottle) and a rebreather makes a good option. And yes, as pointed out by someone else, oxygen concentrations are safe within only a fairly narrow range of 19.5 to 23.5% of the air. Concentrations higher and lower than that range can cause dizziness, unconciousness, and toxicity. However, there is no reason to believe that a rebreather can’t be fitted with a regulator.I don’t for a second believe that nonsense about the FBI tracking you if you have a rebreather – lack of bubbles or not, it is pretty easy to be undetected when diving underwater. If that is the cleverest idea the FBI has come up with to “protect” us, we are in for big trouble. Given that the article you cited is 4 years old, I would say it is more a result of the hysteria following 9/11, than any really sound plan for tracking suspicious activities.",

Your brain adjusts your breathing rate so that you breathe more deeply and more often. Now, say you’re wearing a rebreather that’s not so hot at C02 scrubbing. If you breathe in high concentrations of CO2, your lungs can’t get rid of what’s in your body as efficiently(decreased diffusion gradient). Therefore you start to accumulate CO2 in your body. [C02 gets converted to HCO3- in your body by pulling an OH- molecule off of water and leaving the H+ ]. This lowers the pH of your blood. Acidic blood is very very bad, ESPECIALLY if you can’t blow off the CO2, as in a rebreather situation. Nasty cycle. Nasty death.",

"content": "David, Your comments on how such a system could be made “safer” are correct, but I think you misunderstand a few things:First, the warnings, They are given because rebreathers can *actually, really truly* be extremly dangerous, not because of some goverment conspiricy. Some of the best divers in the world have died while using (professionally designed, NOT HOMEMADE) rebreathers that were functioning correctly, don’t think that something that you cobble together in your privately funded garage will be anywhere near the safety of a commercial system. Divester usually caries stories about fatalities. Hence the warnings: You don’t want to be the next one, please don’t play with rebreathers. Also, assuming that your college Bio and Chem classes will let you figure out all the kinks in the system would be a big mistakeNext, the uses: In addition the the problem of hauling a bottle of pure oxygen (#19 beat me to it), most rebreathers require constant attention, even when you are consuming o2 slowly (at rest), if you are subject to physical exertion, so much the worse. This is why you don’t see them replacing SCBA units in mine rescues, or handed out to folks on the street. Also, for your mass casualty uses (mine accidents, airplane accidents over water, etc.), what is usually needed is a large volume of air or pure o2, which a rebreather cannot supply.Lastly, the essence: What the author wanted to show is that one of the most expensive systems in diving is based on a very simple system, *which still works.* Those who are intimately familiar with these things can often make them from materials that would suprise the average consumer.General thoughts:As to the FBI tracking you, there are only two reasons to use a rebreather.1) to stay down for a *really* long time, and2) to travel underwater undetected over any distance (few bubbles).If the goverment is a little woried about the second, at least they are being proactive about it. Sort of like seeing a person with guest visa looking for a multi-engine jet aircraft rating, you know?And last of all, your quote: “Geez, Im glad the creative minds that pioneered the innovations that have changed our lives over the centuries werent as much of a pussy as you guys.”I might suggest that you look up the creative mind who first managed to produce fluorine gas in any substantial concentration (currently dead due to outdated lab techniques). He might enjoy some company, but no wimps, please . . .For the rest of us, I think the setiment is that we’ll use a professional system, whenever possible.",

UV Box For PCB Exposure
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Hack-A-Day reader [Mindaugasu] built this
box for exposing copper boards to ultraviolet light
before etching them. It has two banks of four 20W UV lamps. The box is lined with reflective foil. The banks can be controlled separately and the exposure time is set by an Atmel AT90. You can change the time using button panel and LCD. He’s got some example boards in his
ARM development
section.

Commercial-grade TIG Welder
|
Eliot
|
[
"Misc Hacks"
] |
[] |
I use the qualifier “commercial-grade” here because this
TIG welder project
goes far beyond our
junkyard TIG welder
. The welder has a 180 amp capacity and has most (if not all) of the features of a modern welder. Instead of using a microprocessor, Dave Barrett decided to use discrete TTL and CMOS logic. That decision should make the design a lot easier to troubleshoot. Schematics and board layouts are on his site.
[UPDATE: I forgot to thank demmion for the tip]

This story as appeared many different places [via
Music thing
], but I wanted to make sure you guys didn’t miss out on the fun.
sCrAmBlEd? HaCkZ!
by
Sven K? is an amazing piece of video remixing software. It’s built using C++, Python and PureData. It takes music videos, chops them up by beats and indexes the samples by sound signature in a database. You then beatbox into a microphone to describe the music you want to hear. The software builds the music you want out of the sample database. Sven has put together an excellent video that describes the program and has example performances. It’s a must watch. Get it either
directly from his site
or
watch it on YouTube
.

Laser Listening Device
|
Eliot
|
[
"Laser Hacks",
"Misc Hacks"
] |
[] |
Laser based listening devices work by bouncing the beam off of a window. Sounds in the room cause minute vibrations in the window. These vibrations modulate the laser beam. The laser beam is then converted back into sound at the receiver. Hack-A-Day reader [Aaron v] decided to
build one of these devices
. It worked, but needs some improvement. He followed plans found
here
(
Coral CDN cache
). I’ve also got a local copy of the
receiver schematic
since there doesn’t seem to be too many of these projects with decent hosting. Williamson Labs has a
good discussion
of the problems these systems can run into and more advanced setups like interferometry.

Shacktopus, The Next Step In Technomadics
|
Eliot

[
"Wireless Hacks"

[] |
Steve Roberts has been doing technomadics since 1983. You’ll probably remember him from his 580-pound
BEHEMOTH
bicycle which he was checking his email on in 1991 over satellite.
Shacktopus
is his latest project. His previous vehicles all had heavily integrated systems, but because of that you couldn’t just grab the communication system and run. Shacktopus is an easy to pack communications platform that contains multiple RF and sensing technology into one device. HF, VHF, UHF, Bluetooth, WiFi, cellular communication are all there plus GPS and environmental sensors. Here’s a
block diagram of the device
. Now, no matter what vehicle you choose to head off into the wild with you’ll be able to communicate with the rest of the world using one device.

[Nate True] states several times that there isn’t any good use for this project, but his
wireless motion sensor
is still fun. The transmitter features a passive infrared motion sensor. It sends the output over the 433MHz band to the receiver module. The receiver has a small piezo that plays sounds based on the PIR’s output. His project is featured

Cody’s Robot Optical Motion Sensor
|
Eliot
|
[
"Robots Hacks"
] |
[] |
[Mac Cody] has continued working on his
original optical mouse hack
. In the time since we first posted the story, he has repackaged the mouse’s sensor so that
it can be used with any robotic platform
. He built a custom board for the sensor and modified a lens package so that the sensor plane doesn’t have to be in contact with the ground. His work is based on a NASA paper
Insect-inspired Optical-Flow Navigation Sensors
. Mac’s sensor seems to be progressing nicely towards his goal of dead reckoning navigation, but he thinks it could do better if the LED illumination was more focused.

For faster robots, this sensor limit will indeed be a problem. The 12 ips specification of the ADNS-2610 is based on a 1:1 lens magnification ratio. As shown in the NASA paper, when the sensor’s focus is set on a surface in motion that is father away, then the resultant ips rate will increase. A future version of CROMS-1 could have a more flexible focus to cover a wider range of distances, allowing for a correspondingly higher ips rate.",

A complete discourse on the design of the PIC interface is nice, if you have to interface to a PS/2 mouse. I like my solution better though: small in size, direct access to the sensor and all of its features, lower power requirements, and (as you mentioned) physical separation of the sensor from the moving surface.",

Xbox 360 Firmware Hack
|
Eliot
|
[
"Xbox Hacks"
] |
[] |
It looks like backup copies of games can now be
booted on the Xbox 360
.
Maxconsole has the video
. This hack is similar to the
final firmware hack of the original Xbox
. The response to the challenge code is written directly in the firmware. So instead of checking the disc, the firmware responds to the challenge directly. Here are the
technical details
. This hack doesn’t allow you to run unsigned code or ignore region codes. All it lets you do is play direct one-to-one copies of game discs.

Network Attached MP3 Streamer

[
"Misc Hacks"

[] |
MP3elf
is a network attached MP3 player. It can stream MP3s from your hard drive or connect to internet radio stations. The design is BSD licenced so you can download all of the plans and build it yourself if you want. They’ve got kits available as well. The server portion is written in Java so it should run on your operating system of choice.

Run RS485 on 2 pair for control and run left and right audio on the other two pairs. The common mode rejection should take care of the crosstalk.",

Macro Photography With A Disposable Camera
|
Eliot
|
[
"Misc Hacks"
] |
[] |
[Greg Lipscomb] from DIY Live gave us the heads up on his latest project:
Macro photography with a disposable camera
. While playing around with the Kodak Max outdoor camera he discovered that the lens was behaving similar to a jewellers loupe that he had. He figured that it could probably take macro shots with some tweaking. He disassembled the camera and then drilled a larger aperture since F11 would have been too small. Then he attached the assembly to the lens from his Canon 10D and fired away. He’s got example pictures on his site; they’re pretty good for something held together by scotch tape.

1-Wire Wireless Router
|
Eliot
|
[
"Wireless Hacks"
] |
[] |
1-Wire
is a low speed communications bus.
OWFS
is the 1-wire filesystem for Linux.
Combine the two with a WRT54G
and you’ve got a cheap wired/wireless network enabled data collection platform. 1-Wire devices are really low cost, only need one wire plus ground, are bus powered, and can even be wired in a branching pattern instead of a normal straight run. OWFS lets you check the status of the devices like they were parts of your filesystem (it’s built on
FUSE
). So, you can do really easy data collection just by writing some file management scripts.

With this hack, I suspect you could use the iButton as a security mechanism.For example, you could mount an iButton reader on top of your WRT54G, then keep an iButton on your keychain with an keyfile of some sort. With some scripting, you could make the WRT54G only allow internet access when the iButton was in the reader, giving you simple physical security to prevent unauthorized use of your network.Or, set up a network of 1-wire devices like switches and iButton readers at your doors and make an internet-enabled alarm system.",

Irongeek’s Wall Of Social Science Majors

Eliot

[
"downloads hacks"
] |
[] |
If you’ve ever read a story about Defcon, the lede probably had something to do with The Wall of Sheep, the giant pojection of every plaintext username and password crossing the network. You may have even seen one of your favorite sites fall victim to it. One of my favorite people, Irongeek, decided to
whip up a little PHP script
so that anybody could set up their own Wall of Sheep style system. The backend is powered by the near-magical
Ettercap
and the script just parses the output into an easy to read format. I think this would be a great warning sign to place on your hotspot’s splash page.

Few things could be improved though,like chaing the shame.php bit in the redirect to..would stop the reload screwing up if the file isn’t named shame.phpAnd to start ettercap, add the linesif($_GET[‘etter’]==”on”){system(“ettercap -Tq -d -m /var/ettertest.txt”);}and access the script with shame.php?etter=on, which would mean you’d not have to manualy start ettercap. Maybe something that checks if ettercap is running, if not it runs the code would be a better way of doing it.. (Check shell_exec(“ps -a”); for ettercap or something..)Irongeek’s site is great, it’s one of the few sites with decent video tutorials, that dont’ start with someone typing in a text editor, which looks.. not the best..

This is coming in a day later than usual; I got my new dual-core Mac mini on Monday and built a new iTunes Library on my NFS server. I then crashed it twice which turned into literal
fsck
ing nightmare. So I finally got it back up last night and started listening to my backlog of podcasts (which has grown enormously now that I can subscribe to them so easily). Highlights from the shows after the jump.
A big
Thank you
to everyone who has stopped by
my Facebook profile
to wish me a Happy Birthday today. I’m 25, my NFS server is running rock-solid, so is my new mini, and I got an official job offer in the mail, so today has been treating me really well.
Happy birthday
to my twin sister Adele, even though the international date line means I already missed it.
Security Now! 29 Ethernet Insecurity
52:14 covers how ARP works and why it is so insecure. This is something that everyone should know, but it may be easier to understand if you read Steve Gibson’s
accompanying article
. He mentions in the podcast an old story about a security researcher’s comments that a lot of hotels still use hubs instead of switches; I found the
story
on Schneier. I think
Irongeek’s article
was my first introduction to the subject of ARP spoofing.
BellCoreRadio 24
45:35 Not much here, but the running joke is pretty funny:
Phoneswarm
posts an interesting payphone number each week. Last week’s was 310-394-9052, a payphone on the Santa Monica pier that just happens to be
visible on this webcam
. The first time PonyBoy got someone on the phone it was a group of
geocachers
that needed their photo take by the cam.
PaulDotCom Security Weekly 17
59:56 My favorite quote: “… to show the guys how they can use CORE IMPACT to test an IDS” “Aww, sweet!” They mention the “
startkeylogger
” IRC DOS attack. They’ve got a
post rounding up security podcasts
as well.
CyberSpeak Mar 4
51:46 This week they talk to Dave Merkel from MANDIANT about their
First Response
tool that is currently a free download.
Live Ammo Digital Forensics and Hacking Investigations, Part 4
36:15 More hardware/software tools and ARP.
Blue Box #18
35:57 Covering SPIT, SPam over Internet Telephony.
TWAT 74 BitViper WRT Hacking
36:39 I listened to all of the podcasts that came from TWAT radio this week, but this was by far my favorite. If you’ve got a Linksys WRT54G and don’t know where to start, BitViper and PowerStick do a kick ass job covering all of the ins and outs of the device and the multiple firmwares available. Even if you are well informed about the WRT, you will probably enjoy their personal story about doing a long run with multiple WRTs and some clever hardware hacking: start at 27:00. Great job guys!
In the Trenches
1:00:48 I think the idea of the test crashing during an
MCSE
exam is hilarious. They’ve also got a funny story about using a $600 Cisco router in the home. It ended up giving them 8Mbps instead of the regular 2Mbps from the Linksys WRT.
If you are interested in Weblogs, Inc. or just where this company came from you should check out the
interview with my boss
… or at least follow the link to see whose t-shirt he’s wearing.
…and if you’re following Catty Girls Discuss you’d hear
Brigitte’s plans to buy an inflatable boat

Qtopia On The GP2X
|
Eliot
|
[
"handhelds hacks"
] |
[] |
Trolltech’s Qtopia is the application platform/user interface of choice of Linux handheld device manufacturers. It doesn’t matter if it’s a phone, PDA, or single application device. Hacker NK has successfully
ported the GUI to the GP2X
. With
USB host mode
,he’s been able to surf the web with Opera while using a full keyboard, mouse and WiFi adapter. The Sharp Zaurus PDA uses Qtopia with an ARM processor too and users have reported success pulling applications from the Zaurus software repository and running them on the GP2X. Here are some photos of the action
one
and
two
.
UPDATE:
Commenters say that the GP2X forums have a Windows trojan. I think you’ll be fine if turn off Java.

Pentium M Overclocking
|
Eliot
|
[
"computer hacks"
] |
[] |
Laptops based on the Intel 915 chipset have a 533MHz front side bus and ship with a matching Sonoma processor. Dothan laptops only have a 400MHz FSB. If you pull the BSEL[0] pin on a 400MHz FSB Dothan CPU to low you can trick the 915 into thinking it has a 533MHz FSB CPU. This will gain you 33% more processor speed. Almost every other pin on the CPU is a ground so you just insert a U-shaped piece of wire into the processor socket to connect the two pins. If the system becomes unstable you may have to bump up the processor voltage (which involves another piece of wire). In the article, Dan Zhang is able to
take a 1.8GHz Pentium M to 2.4GHz
. It’s a pretty simple mod, but you have to go out of your way to do it since Sonoma laptops never shipped with a 400MHz FSB CPU.

Canon PIXMA CD Printing
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Canon’s first consumer printer capable of printing directly on CDs was released in 2003. Unfortunately for anyone in the US, this feature wasn’t included. Canon just put a plate over the CD tray slot.
A community has sprung up
to assist people in activating this feature. You need to remove the cover first. Then you can install the CD tray which you either purchased or constructed following their plans. The final step is to set a registry key so that the CD printing menu appears.

Disposable Camera Flash Slave
|
Eliot
|
[
"digital cameras hacks"
] |
[] |
[Greg Lipscomb] was working on this
disposable camera based slave flash
when he stumbled into his
macro photography project
. Slave flashes are used as fill lighting and can be triggered by several different methods. Greg’s project uses a photocell and a microcontroller for trigger and timing. It also makes sure the flash stays charged. He concedes that this design is a bit complicated, but he went with it because he didn’t have any
silicon controlled rectifiers
available. The microcontroller would be too slow, but his Canon 10D uses a pre-flash before the actual photo, so the slave has a built in delay from that first flash.

There are much easier ways of doing things, but nothing gives you the control that a microcontroller gives. That was the purpose of this project. It was a learning experience with microcontrollers.

XP Booting On Intel Macs – Game Over

The
WinXPonMac
contest has officially announced “narf2006” and “blanka” as the winners. The solution should be released soon. With this new development the only reason not to run XP on a Mac is that XP sucks… which is a pretty good reason.

"content": "Wow Steve some people just don’t get it do they? Using a mac has nothing to do with being a “fanboy”. I bought my ibook about 8 months ago and it was the first mac computer I ever owned. I didn’t buy it because I worship apple, I happened to like how it looked and I was interested in trying an alternative operating system that wasn’t Linux. I happen to enjoy using my ibook because I work in the IT dept of a company all day fixing windows computers and don’t want to come home and fix another one.In the 8 months I’ve owned the ibook I think it has crashed only twice and I’ve only had to fix it otherwise about once or twice and that’s only because I’m a bit of a power user. If I had been using a windows laptop I would have already reinstalled the OS at least once due to spyware. One of the biggest reasons to use a mac is that there is absolutely no spyware (that I’m aware of anyhow). Also I tend to find that apple programs are usually much more polished than windows apps.It’s really just a matter of personal preference not “uniqueness and style”. I happen to like the way it looks but I didn’t buy it to be unique. And by the way there is an extensive software library available for Mac OS if you hadn’t checked lately.Your comments make you sound more like a Windows/PC fanboy than anything.",

Windows Has it’s strengths as does linux as does mac os. Calling one better is childish. You would be surprised about the amount of software available for all 3 platforms. Drivers are always going to be a problem no matter which platform you use. Windows does have more drivers, however this increases the likelihood of conflicts and instability. Linux has tons of drivers however most are open source and range from great to highly unstable. The OSX has more drivers than one may imagine and there is work on porting many linux drivers to the Darwin Kernel.As for the cost yes macs are more expensive, apple makes it’s money by selling hardware the prices will go down as a function of there market share. Some people believe the cost is worth the ability to legally run the mac os.Windows computers can range from beautiful to a rats nest of wires in a cardboard box. The nicer cases usually cost more.As more and more of the population become more dependent on computers and further integrate them into there lives. There will be more of a call for stylish computers that look good in your house.If you like windows use it.If you like linux us it.If you like mac us it.At least try all the platforms before you call one a piece of crap, and keep in mind that there is a portion of the population that is going to disagree with you.They are not wrong, neither are you. Telling them that they are stupid for using their platform will just make them hate you and your platform and make them less willing to try something perhaps better.",

I think its good alternatives exist, because thats what makes things to evolve.People often say that Windows is a n00b OS, and that Linux is for uber leet, well …1st of all, it all depends on what you want to do with it. There are experts users on both (and other) OSes. I bet a Script Kiddie has Linux installed just because it is cool and has no idea of how to properly work with it. Also, I know allot of people that have a very good understanding of IT and use Windows XP.There are different levels of users for any given OS, and most of the Windows XP trash talkers *are not* the Windows experts.I do not wish to start a war, cause I’m already sick of those.

More market share = more reason to target, and more people with the expertise and resolve to do the targeting.

"content": "Funny, how come everytime windows on macs is mentioned it startout to be a really big discussion.First of all as a proof of concept i think it is great that somebody is trying to get windows work on a intel based mac! I have and probably we all have seen it the other way around (OSX on a pc).I myself wouldn’t install windows on my mac as it has no extra value for me, i am a graphical designer and in the world of graphics most companies work on mac.I do fell in love with mac the very first time i ever touched one, just because it is stable and easy to use.Second, if i have to be really honest about why i think apple is better, then i have several reasons. One is there warranty policy its so much better as any pc’s i came across. I had a broken mac G5 (which was clearly a monday morning monster), after several repairs apple provided me with a new machine and upgraded it for me with a faster processor. (okay its in the price of a mac i guess, but still..) I also think that memory management is much better on a mac, one of the reasons why a 1.8Ghz mac can easily outrun a 2.x Ghz pc (we all seen the tests)I also had linux machine, this was great for a while untill OSX came out, i quickly build a OSX server, why? just because i was more “at home” with its interface then with Linux, so this was purely a thing of taste.The only thing i have a windows machine for is bookkeeping since i have my own company and i couldn’t find a bookkeeping programm that fitted my needs, i run a while on iProfit but that was in the early stages and had some major bugs in it (i guess they solved it by now)So in short i have all 3 platforms but i’ll stick to my trusty mac just because i love the simplicity of its OS, i didn’t buy it for design although it looks great on my desk, i didn’t buy it to show off. I bought it because it is my tool and a tool that i always can count on.",

Super Soda!
has been posting a lot of projects, but this is one of my favorites. We covered
otherpower’s wind turbine
a while ago, but
Damon Vander Lind’s turbine
features hand-laid fiberglass blades. The core of each blade is hot wire cut out of pink foam by following a wooden airfoil pattern. The fiberglass is laid all at once with five layers at the base and two at the tip. Each layer is slightly offset to handle torque. The entire assembly is mounted to a permanent magnet generator contained inside an alternator case.

I’m sure many of you remember me recruiting a new writer to work with me on how-tos for Engadget.
Will O’Brien
was one of the many who answered the call and has been cranking out quality projects. Today’s is
modifying a standard R/C transmitter for use as a computer joystick
. This “trainer” can be used with flight simulation software so you can practice flying without risking your plane. This is the first step in a future project.
Check out Will’s previous posts:

VW CD Audio Interface Adatpter

[
"Portable Audio Hacks"

[] |
I had been meaning to post K9spud’s
VWCDPIC audio interface adapter
ever since our first
auxiliary input
hack… and today I finally remembered to. It really is one of the best out there. Normally the the Volkswagen OEM head unit has the CD changer channels muted unless you’ve got a factory changer. The VWCDPIC interfaces with the already present CD changer plug and fools the head unit to connect any audio device you want. It also provides remote control of your audio device using the head units buttons. It’s very clever and can work with any audio device.

Snake robots
are already freaking creepy; so who had bright idea to make sea serpents?! You can find a few details on the
ACM-R5 at TechEBlog
. It can swim 30 minutes on a charge. So, the impending revolution will either be short lived or our destruction will be incredibly swift.

[Refik Hadzialic] has updated is site with a how-to that could be rolled into many different projects. Using a receiver and transmitter pair from Laipac he demonstrates how to
communicate wirelessly between two microcontrollers
. The pair costs about $12 and operates at 315MHz. He’s got a chunk of commented code in the article to give you an idea of how it works.

. Since it is slot based you can just etch contact pads onto a circuit board and plug it in. The hard drive inside uses standard connectors, but this adapter will keep you from opening the case, voiding your warranty. It will also be much quicker to use daily. You can use
Xplorer360
to get full read/write access to the drive. They’re selling the adapter in kit form for $17 and assembled for $20, but the high res pics show how easy this is if you just want to build it yourself.

Controlling A Cheap Color LCD
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Spark Fun Electronics has made a name for themselves recently by selling interesting parts like this
$20 color LCD
. Hack-A-Day reader [Refik Hadzialic] decided to buy one and
see how easy it was to use
. It is a 128×128 display and should be a clone of the one you would fine in a Nokia 6100. He wired it up to an ATMega32L-PI8 microcontroller. He grabbed source code from a couple different places and eventually got something to work. In the end, the actual control commands seem pretty simple. Refik has been posting a lot of quick projects and info on his site,
e-dsp
. Have a look.

LEGO Announces NXT Beta Testers… Officially
|
Eliot
|
[
"Uncategorized"
] |
[] |
Yesterday LEGO announced that they had
picked their 100 beta testers
. They represent a broad cross section of blah, blah, blah. I’m not sure if I should be annoyed that I didn’t get picked or feel sorry for our buddy Jason Striegel who seems to be the
only person that was officially denied
. Oh well, time to go spend this extra $150 on Mega Bloks.

Exhaust Flame Throwers
|
Eliot
|
[
"Transportation Hacks"
] |
[] |
Here’s a hack that’s been around since the very start of the hot rod movement. Car
exhaust flame throwers
work by interrupting the spark to the engine. This dumps raw fuel into the exhaust system. The fuel is ignited by a coil and spark plug placed right before the exhaust tip. Doing this will shorten the life of your engine (and pedestrians). The raw fuel strips the oil off the cylinder walls and contaminates the oil causing more wear and tear. Also, this mod can’t be used on a fuel injected car. It would foul the O2 sensors and catalytic converter. Never the less, our fascination with electricity will live on.

If you wire a secondary ignition coil into your car somewhere (preferebly close to the tailpipe, I’ll explain why in a bit) and wire one terminal on that to the battery. Wire the other terminal to a switch, and wire the switch to a ground somewhere on your car (slip the wire under a bolt that touches the chassis, or something metal would usually work.) What this will do is produce a spark every time you throw the switch on, then off again. It works this way due to the nature of the coil. The spark comes out of the HV (High-Voltage) output on the coil, and arcs to the ground on the car (i.e., almost any metal on the car, tailpipe, chassis, engine, ya know). The coil ought to be close to the spark-plug because pulses of HV electricity don’t travel as far as 12 volt battery-style stuff. Any more questions, just post.",

If you wanted to interrupt the engine spark its easy with an MSD AL6, or AL6-2 select a low value for the 2step rev limit hit the rev limit swtic and rev the engine and it will randomly drop the spark from 1 cyl. The same cyl will never be dropped twice in row to prevent the washing of oil from the cyl walls. “raw unburnt fuel” (Sounds scary dont it?) is in you engine for 2 out of the 4 cycles anyway…Oh and to the guy who put a switch to the ignition coil and the battery, and rigged another switch to cut all the spark plugs.

Just drive the Coils with a 555, hell even a heavy duty relay setup to act as a buzz coil. If you want it alittle bit more complex use a MCU to monitor the transmission tach and time the fuel pump to pulse just befor the exhaust cycle release, ensureing little to no fuel is pulled by backpressure.

Replacing Motherboard Chips

While most users aren’t going to attempt to replace a single failed chip on a motherboard, [joeboy] felt that it’s definitely something the Hack-A-Day audience would try.
Project Oxcart
details the process he and his coworkers went through to replace the Firewire chip in a laptop. It had failed during a power surge and Dell wanted $1100 for a replacement motherboard. They opted to buy the $5 chip from Digikey and install it. The write up details the many steps involved in the replacement of the chip, which took the entire day.

We had 4 100+ pin ICs (not to mention the 100 or so other smds) and being n00bs, we messed up from time to time. We also found that with patience, coordination and timing, you could use desoldering braid to get these guys off. But you have to be carefull if you want to salvage the chip, if you yank off the braid, it will bend the hell out of those pins. Just clean up the pins and mount sites with a fine tip on your iron and you should be OK.Also, I would be concerned about using the pick and especially the toothbrush for causing ESD damage to the other chips connected to those traces.",

When the box showed up at home, I could hear that the heatsink had broken free (I had used nylon screws, yeah I know, save it) and was loose inside the case.When the heatsink had broken free, it slammed into the nearest ramsink (on the video card) ripping the chip free from the board, and pulling up/out some pads/traces with it.To make a long story a little shorter: after 4 hours using: a microscope, a very steady hand, and a superfine soldering iron tip, I was able to resolder the chip back in place (using the pads that had not been ripped off) and soldering to what was left to the traces where a pad had been ripped off the board.To this day, the board still works fine.The memory doesn’t overclock like it used to, but hey….Oh and a side note, you wont be able to do this to modern video cards as they use BGA style ram.Well if it did rip clean off you might be able to reflow it back on with a hotplate and hotair tool.",

Fedex Kinko’s Smart Cards Hacked
|

[
"Uncategorized"

Researchers at
Secure Science Corporation
have managed to
break the ExpressPay system
used at FedEx Kinko’s stores which is provided by enTrac. The cards are write protected using a 3 byte security code. You can sniff this data using a logic analyzer and then use the code to write any data you want to the card since it is unencrypted. The security code is the same across all cards. FedEx Kinko’s stated that the article is inaccurate, so Lance James and Strom Carlson made a
video of themselves doing the hack in the store
: They put $1.00 on a card at the kiosk and then use it to log into a computer and show the balance of $1.00. They logout and use a separate laptop and card reader/writer to change the balance to $50.00 and modify the serial number. Next they use the card to log back into a computer and show the balance of $50.00. They let one minute pass so that $0.20 is charge to the card. Finally they logout and use the self-service kiosk to print out a receipt showing their balance of $49.80 with the fake serial number. At this point the attacker can take the card to the service counter and ask for the balance in cash.

[fix: I had originally stated they bought a new card at the kiosk]

"content": "Hey all,I’m a Fedex Kinkos employee but think that this is a great hack as it was bound to happen! Anyway, here are some things they didn’t mention, that i know about the cards from working there.There are three card types… Purple, Blue and Green (Green is the Skeleton key.. read on).* Purple cards have a stored value. Money can be added at the kiosk or at the counter, and can also be refunded at the counter, but you have to fill out your name, phone number and sign for it.* Blue cards are called convenience cards. They can be preauthorized at the counter to make either 10 or 25 copies, so that the person can just make a few copies and pay after, instead of getting a card. They expire after 24 hours.* Finally is the mega card, the green card. Green cards are for EMPLOYEES ONLY. They can be activated for 24 hours using any employee’s name. Once activated they can be used to make unlimited free copies or minutes on the computers, and are so that we can do copy jobs in the express area without having to pay. The green card can also be made into a config card which lets you mess around with the server settings on the card readers.If someone could someone change the type, they could have access to all of these functions. Good luck and hopefully corporate will fix this soon!",

Use a microcontroller of your choice, or laptop serial port to record the communications between card and Kinkos reader; emulating what a logic analyzer does (and later downloading to a computer, if you chose the microcontroller path). locating the three reference data bytes is trivial.2.) Use a microcontroller of choice (as i’ll be doing this weekend) or PC’s parallel port to brute force thru the security codes 2^24 possibilities – attempting 3 at a time, reset power, reset/memread command, then repeat until found. Expect it to take the better part of 24hrs, your mileage will vary.

However, their drivers may be crippleware, and then you’ll have to reinstall with generic PC/SC drivers. Try looking at its datasheet if they give one, and poking around its drivers with a tool called Dependency Walker. it’ll be a DLL in the system32 folder. Google the exported function names, and see if you find another SC driver with a similar naming scheme..**Also for those buying the ACR30 .. you’ll have a hard time programming for it if u don’t buy the 99$ SDK kit. Without either the ACR30.h header file, or information of the SCardControl() command to select the card type, it wont be able to read memory cards (like Kinko’s) without first changing this option. I’ll try reverse eng it later this week .. but if someone successfully has, or has ACR30.h/ACR38.h .. feel free to email it to arserbin3 at yahoo dot fr ^^ (fr not com)",

However in my experiance management never enforced this policy except at one store, and even in that case the customer can make up completely false information as we don’t check their actual ID.Quick question, why does this seem so much of a longer process than it looks in the video? do logic analyzers connect to the stores card readers or to your own? and what is #48’s method? does anyone have his page saved, the page is now gone…",

IR Audio Bridge

Eliot

[
"home entertainment hacks"

[] |
Reader [
Chris Rybitski
] had a pair of RCA IR headphones laying around from the Radiohut. He’d never really used them and decided they would be much better suited as a
wireless audio bridge
between his computer and stereo. Since it was going to be a permanent installation his first task was to find a wall wart to power the receiving end. He then reboxed the receiver in an old laptop battery case with the IR LEDs from each ear and an output jack for his stereo. Not to complex, but I’m sure the system works a lot better now that it is in a fixed position instead of strapped to someone’s head.

Hack Media: Security Podcasts

"Uncategorized"

Here are some security podcasts from the last week. Feel free to suggest additional ones. There is never a shortage of podcasts on the internet, about the internet.
Security Catalyst 19 The Secrets of Risk Management (With Ron Woerner)
25:33 SC was suggested last week by sometimes co-host [
matt yoder
]. It’s a nice interview with Woerner about his experience implementing a risk management program at a large company. I was happy to hear about several upcoming security conventions in Omaha (i.e. ones I don’t have to fly to). Michael Santarcangelo does a great job hosting too.
Security Now! #28 Listener Feedback Q&A #4
40:24 [sentinel] corrected me last week; the ARP spoofing show is next week. This episode does maintain some interest because it is structured by listener questions. Leo mentions that he might make his OPML file public since he tracks about 50 sites. I was thinking about doing this. I’ve currently got about 160 sites in
Bloglines
(I trim the fat from time to time). It’s certainly no comparison to the 500+ monster that the Engadget writers maintain.
PaulDotCom Security Weekly – Episode 16
51:18 was suggested by co-host [Larry Pesce]. This is a pretty fun group podcast. They mentioned a favorite quote by Geer at ShmooCon, “We need security because at any moment the bad guys are only 150ms away; just ping China”. They also pointed out that there is a
GPL version of the Spinning Cube of Potential Doom
.
CyberSpeak Feb 25
72:08 Lots of interesting stuff coming from the feds. It starts with Mike Younger discussing some of the problems in validating email since Outlook and Lotus Notes both let you edit messages you’ve already received and ones you’ve already sent. They point out a nice
deny hosts script to prevent brute force dictionary attacks
. Check the entry’s comments for other solutions. They also mentioned that you should check for firmware updates for your firewire write-blocking devices if you want to read the HPA of a drive. The LiveAmmo podcast from last week specifically stated that you should avoid USB and Firewire write-block devices because they might not be able to access HPA.
LiveAmmo: Digital Forensics and Hacking Investigations, Part 3
46:12 is not nearly as dry as it was the previous weeks. It covers the data collection process and what sort of slip-ups might happen. They suggest reading NIST Special Publication 800-61:
Computer Security Incident Handling Guide
.
SploitCast #007
44:01 As promised last week, this is an interview with Lance James. This is my favorite podcast of the bunch this week. Lance covers many of the techniques that phishers are using. They’ve been going so far as do distributed hosting of their phishing websites on 0wned computers. Lance also talks about the server-side tools he has been developing to fight malware. The burden is being placed on the server since you can’t expect the users to keep themselves safe.
Blue Box #17
41:00 Another week, another excellent VoIP security podcast.
I promised my friends Cara and Brigitte that I would promote their podcast “
Catty Girls Discuss
” hosted by the local paper. I hadn’t heard it at that point, but the title kinda gives it away. Here are the highlights from the first show: 10:00 they realize they’ve run out of topics, 15:00 they realize they’ve run out of topics, 20:00 they realize they’ve run out of topics. No, it’s not really that bad and can be pretty funny. Direct links to episode
one

Tick Destroying Rover

[William] from
GoRobotics.net
sent along this tip about a tick destroying rover built by students at VMI. The truck uses inductive sensors to follow a wire laid around the perimeter of the lawn. By releasing CO2 along this strip of grass they can attract ticks into the area (animals expel CO2). The ticks collected are treated with Permethrin. Since the application is targeted, it is far safer and cheaper than spraying the entire lawn. The students also suggest that repeating the run over the course of three months would break the tick’s life cycle, making the area tick free for several years. Here’s
Wolfgang’s write-up

one
and
two

Risto K?’s
PC to R/C interface
let’s you connect to your Futaba radio transmitter. You can use this device to do direct control of your R/C project: prewritten trajectories, user called macros, or direct PC joystick control. He’s built two versions. The original one used multiple D-latches. The second version was an attempt to reduce the number of components. It uses interrupts in the microcontroller software instead of the latches. This would normally cause a lot of jitter, but Risto implemented the interrupts in assembly. The controller can handle up to 16 channels. The LCD displays the last pulse-width and channel.

If you want it to go full left you send a 1ms pulse, and if you want it to go all of the way right you send a 2ms pulse; to make it center you send a 1.5ms pulse. So if you wanted to use a gyroscopic mouse you would need to write code that takes the signal from a mouse and converts it to the pulses for a servo (not an easy task)If you just want to use a joystick you best bet would be to get a cheap set of transmitter and receiver from your hobby store (should cost like $30), and take the circuit board from the remote and attach the joystick’s variable resistors where the remotes were.",

In that case, using pulses to control servos, they can only go to the extremes of left and right, and center, or can these pulses be used for incremental movement for precision servo control for a tracking base?Thanks again, if I find out better how this can be done, if it can be done, without a PC in between, I will go off to study this stuff in depth until I make it work.

FON Arrival

Eliot

[
"Uncategorized"

[] |
Just a quick note: I received my
FON router
today. It’s a brand new Linksys WRT54GL with DD-WRT installed. With shipping it only cost $33. If you want a WRT that is guaranteed to run Linux, this price can’t be beat (if you’re in the first 3000).
P.S. I also received a
big order
from Jameco. Their “100 asst. sockets” doesn’t seem to have a single straight pin in it.

I did this within the 1st 5 mins to be able to get the registration page on any website i access in browser. this was the tricky part as the fon router needs access to the net to register the FON router ( and then allow access to any fonite afterwords).now when I have a friend comme round, he sees the fon wifi signal, connects to it (there is no encryption/passwd) he opens up a browser and sees the fon login page (login created on the fon website).it all works the way it should, but I put the fon router in a DMZ so as to seperate my networks from each other. I am working on securing the whole thing.I hope all this helps.good luck=)",

Rundfunker – WiFi, MP3 Streaming Radio
|
Eliot
|
[
"Portable Audio Hacks"
] |
[] |
I think the first time I saw the “
Rundfunker
” I had ignored it because I though it was a commercial product. In reality, it’s a scratch built WiFi streaming radio that has the finish quality of a commercial product. The radio connects to your wireless network and scans for available MP3s. You can select the MP3s using the front mounted rotary encoder and LCD. The main board is a VIA EPIA MS10000E LVDS. It was chosen because most of the features are pin headers instead of ports. It’s also passively cooled and boots a custom Knoppix build from the compact flash. The controls are connected using an ATMega 168. The software is written in Java and features a web interface and remote control identical to the front panel. There’s a great write-up about the project on
mini-itx.com
, full source on the
project wiki
, and extensive
photo gallery
.

"content": "having done a lot of research into mini-itx systems, let me tell you some of the costs. mind you, this information is off of the top of my head, so don’t expect too much accuracy or good grammar.———————————————–motherboard: size, size, size! the standard is mini-itx, IIRC is a 7 inches x 7 inches. Most mini-itx systems come with processor connected to the motherboard already, however some of the upper end models ($200+) will have a socket. In reality, if you are considering an ITX solution, you are looking for size and power efficency, so I would not waste my money on trying to cool a high end processor.via ITX motherboards have a processor range from around 800mhz to around 1.2Ghz. They come with lots of features packed into them.another solution for small boards is ebay. Search for “SBC” or “Single Board Computers”. These were industrial boards, and can have a variety of specs. I have seen some custom boards be 3×5 inches or smaller. You will either catch a deal and get one of these for cheap, or end up paying $175-$300.SBC’s come with varying feature sets and processing speeds. Keep searching ebay and you will eventually find one.a third option would be to search ebay for “thin clients”. these machines used to be nodes on a corperate network. They often have small motherboards (although slightly larger than itx). The main thing about these machines is the price: One can get a thin client that has a 400mhz or 600mhz processor for $10-$30 on ebay. where they gain in price, they lose some in functionality. most thin clients have crappy expansion capability. If you go this route, expect to utilize USB devices.———————————————–power supply: My ITX motherboard is running off of a 90w PSU. it’s only power consuming device is a 200gb hard drive. You don’t need or want much power for your small form factor machine.You have two routes, a standard power supply or a DC-DC power supply. if searching for a standard power supply, try to get your hands on one that was made for an itx or 1u/2u (server rack) system. these are often smaller (in wattage and in dimensions). some hackers remove the metal casing from their psu’s to conserve some space. you can find these power supplies from $25 and up.if space is really a premium, you have to go with a dc-dc converter (like in the article). these will plug into the power socket on the motherboard, and attach the motherboard to an external dc power supply. I’ve seen these as cheap as $40 for the dc-dc converter, however, one will still have to purchase/find-in-their-closet a external DC psu.if you go with the thin client route, they often have proprietary power supplies that come with the machine.———————————————–storage: you can go massive or solid state. decide what you need and either get a large hard drive, a laptop hard drive (and adaptor to go from 44 pin to 40 pin ide) or a compact flash to ide adaptor.keep an eye on the specs of your machine. some small form factor boards that have an ide connector might use a 44 pin ide cable. with one of these, you could attach a thin laptop hard drive with no adaptor.on some thin clients, they have a “DOC”, which is also known as a disk on chip. it’s a 30-90mb module on the motherboard that you can boot to. one could roll their own linux distro in there and have some fun.———————————————–case fab: what are you going to case it in? aftermarket solutions cost $100+. a creative hacker could get their hands on some plastics (lexan, uhmw-pe, etc) or some cheap metal to make their setup. prices will vary depending on your thickness. if you are determined, you can do your case fabrication with your dremel (you have a dremel, right?)lcds: lcd’s cost anywhere from $10-$80, and come with varying features. on their own, you can wire them to a serial or parallel connection. you can also wire them to a microcontroller. Features you need to note before buying a lcd are: its rows, columns, if it has a backlight, what chip is used to control it. the most common chip is the hitachi 44780. there is a load of software and tutorials out there on how to use it.controls:knobs (potentiometeres), switches, buttons, one can get them from all over the internet for cheap. again, you can attach them to a microcontroller easily.microcontrollers: take your pick, most can be sampled for free from the producer (especially PIC microcontrollers). Either build a programmer for $6 in components, or buy a cheap programmer for $10-$15.———————————————–feel free to keep the conversation going with questions.",

Palm Zire 71 Resurrection
|
Eliot
|
[
"handhelds hacks"
] |
[] |
Reader [steve diraddo]’s Zire 71 had given up the ghost long ago, but with a strong desire to annoy his friend,
he decided to resurrect it
. Unfortunately, like most things that rise from the earth to feast on the brains of the living, Steve’s Zire has limited capacities. When he had originally disassembled the device it was because the camera had stopped functioning, it couldn’t sync, and failed to charge. If he was going to do anything with the device, he would need to get it charging again. The dock connector no longer worked, so he grabbed the pinout for the internal connector from
pinouts.ru
. By following the traces, he was able to solder a USB cable directly to the board and start the device charging. There are also narrow USB data lines on the board, but Stave didn’t trust his hands to solder them. Programs can still be loaded via IrDA or the SD card. Plugging the screen back in and loading up
NoviiRemote
he had an ugly, but still very functional toy-to-annoy.
On a related note, [Radu Privantu] sent along his write up:
How to use a Pocket PC with a broken screen
. Even though it doesn’t have a screen you could still use it as a thin client for streaming music, as a skype phone, a WiFi camera, or a dedicated development platform.

Underwater CVS Camcorder
|
Eliot

[
"Portable Video Hacks"
] |
[] |
[Everett] got such a great response to yesterday’s nightvision hack he decided to write up this
underwater CVS mod
. The outside is a
Pelican #1010
case. The camera fits almost perfectly inside. A small foam shim is used to position the camera lens between the two thick plastic ridges. Everett relocated the power button to the front of the camera and placed a guard around the shutter button on the back. The shutter is now wired to a reed switch at the back of the case. To start the camera recording he’s attached a magnet to a spring on the outside of the case that you slide over the reed switch to trigger it. If you missed it yesterday, he added an
example shot from the nightvision cam
. It isn’t swimming season so the only underwater pics he has are from the bathtub, which he luckily hasn’t posted. If you want to start hacking on a CVS cam, [
morcheeba
] warns that they still haven’t completely broken firmware 3.62 and above.
Here is the FAQ

Extra time, money and effort going into some ridiculous disposeable camera armor that obscures the camera’s view. Look at the thing. It has a plastic ridge right over the lens.

Digitally Reading Analog Gauges
|
Eliot
|
[
"Misc Hacks"
] |
[] |
While working on his masters degree in controls and robotics, Hack-A-Day reader [Kenn Sebesta] developed a cheap method for
digitally reading analog gauges
. This method was necessitated by needing to take over 3000 measurements using a dial indicator during his thesis work. The system is implemented in Matlab and uses a webcam to take a picture of the gauge. Once picture is taken it goes through several steps: First, it is reduced to a single color. Then, edge extraction is used to find the lines. Next, the lines are thickened. Finally, the Hough transform is applied to find the longest line: the needle. All that is left to do is measure the arc back to the zero point and match it to your scale. Using this method Kenn’s laptop can take 4 measurements per second.

I didn’t incorporate it out of sheer laziness on my part. The hough transformation is exactly one line in matlab. What you propose is much more complicated, believe it or not.What’s surprising about computer vision is that it’s incredibly hard for the computer to do what we do so naturallly.

Hack-A-Day Extra
|
Eliot

[
"Uncategorized"
] |
[] |
The
tip line
has been pretty dry lately. Not really a lack submissions, just a lot stuff I can’t use because it has been covered everywhere else, like the
multi-touch display
. I’m not going to dedicate an entire day to something that’s already been on Engadget, Make, or Slashdot because you guys would be seriously pissed off. Reader tips drive this site and I would like to thank everyone that sends them in. You’re the reason this site stays fresh and original.
The
Team Hack-A-Day
folding team is looking for ways to boost production (being #47 is pretty good though). If you don’t know what the team is about, [Billy the Impaler] has a Valentine for you:
The New & Improved Illustrated Folding@home Guide
.
The #hackaday channel is still alive and well on EFnet. More links after the break.
I hired
Will O’Brien
to write Engadget how-tos with
Dave Zatz
and me. His first one was this week:
How-to:Scale video for better HDTV viewing
.
I’m sure I’m not the only dork here waiting for the
Penny-Arcade
CCG to be released. The website for Sabertooth games promises to send you a
free Soul Calibur III and Street Fighter demo deck
if you send them an email. It’s to promote their Universal Fighting System, so all of the cards should work together. You could kick Gabe’s ass using Talim; It would break his heart.
[nbalmer]’s
Paris Hilton Operation boardgame
shocks the player. I’d like to see a guide for scratch-building Operation style games.
[henning]
blew up a RAZR
.
[Philip Mullis] help set up a
wireless link in a really RF unfriendly environment
. Nice use of old satellite dishes.
How-to convert S-Video to composite
[TGOS]
Did you catch the update to the
proximity card spoofer
post? Jonathan Westhues’s work was
mentioned on CNN
.
[Niacin] now has
video out working on his MSN TV cluster
.
[Paul]’s
Zero Footprint PC
or what to do when your laptop screen breaks.
[redwolf]
fixes the power port on his laptop
.
Russia accused Britain of planting a “spy rock” in a Moscow park. [Sean Hillmeyer] decided that the US can’t be left behind in this rock based arms race and
built his own
.
[Nick]’s
Network based IR remote control
[ex-parrot]’s
PIC implementation of Donkey Racer
[Matt]’s
light-up vintage telephone ringer
[StephenC_IRL]’s
PhonEY bluetooth decoy phone
Thanks again to everyone who sends in
tips
.
UPDATE:
Crap, I forgot to include [squidjam]’s experience using
Desitin
as thermal compound (I didn’t know what it was either):
I recently used
Desitin
as a substitute to thermal compound in an “el cheapo” generic aircooling system (mega or omega) when the wax that came with it failed to work.
I used a dremel (with the soft polishing and shine tip) to remove all of it from both the heatspreader and the p4 3.06 Ghz. then i applied a generous ammount (no more than 1 mm thick spreaded over the processor) and installed it all.
It worked, the darn thing didn’t go further down from 69 degrees celsius and it went down to a maximum of 52 when doing heavy work.
It works because thermal compound (the white one) is made with zinc oxide

Hardware Keylogger
|
Eliot

[
"Peripherals Hacks"
] |
[] |
Keelog.com has a really concise description of
how to build a PS/2 based keylogger
. The main components are an AT89C2051 microcontroller and a 24C512 serial EEPROM. Once it is plugged in, the device begins recording all of the codes generated by the keyboard. The data can then be dumped using their keygrab software.

Because they are I2C devices, up to *EIGHT* can be connected using the same two data lines. Each eeprom needs to have a unique id, which is set by connecting each of A0, A1 and A2 on the eeprom to either it’s ground or Vcc pin (the Keelog logger has them floating, which is probably a bad idea.) Then the microcontroller can select which chip to use by sending the corresponding ID.Both of these require the microcontroller code to be altered, good thing they supplied source code :)",

RC Car Telemetry
|
Eliot
|
[
"Transportation Hacks"
] |
[] |
Meghan Desai and Yiling Li built this
radio controlled car telemetry system
for their “Designing with microcontrollers” class. They had looked at several other RC projects and decided it would save a lot of trouble if they didn’t attempt to work with the car’s on-board microcontroller. They built separate boards to house the four IR sensing pairs, temperature sensors, accelerometer, and an Atmel Mega32. All of the collected data is transmitted at 433MHz. On the receiving end is another Mega32 that processes the data and formats it for display on a TV. They’ve done an excellent job documenting their project.
If you have to do a design project this semester, we’d love to see it. Just get some free hosting from
Blogger
and post your project. I’m using Blogger as an example since they don’t crash and burn when we link to them.

Willy Volk interviewed Lloyd Godson for
Divester’s latest podcast
. Lloyd is building a self-sustaining underwater habitat: the
BioSUB
. It will hold at least 15 square meters of engineered wheat to convert CO2 to oxygen. He also plans on testing Alon Bodner’s
Like-A-Fish
tankless SCUBA technology. The system works by lowering the pressure of the seawater to extract the oxygen. The BioSUB project is sponsered by the Australian Geographic Society and Lloyd plans on launching this August.
A quick note: if you caught my friend’s dance/electronica radio show last week, it’s on again tonight 7-9PM CST.

RepRap: The Replicating Rapid Prototyper
|
Eliot
|
[
"Misc Hacks"
] |
[] |
The
RepRap
project hopes to build a universal constructor; a machine that can replicate itself and make a number of useful products. The machine is open source and uses fused deposition modeling (FDM) to layer melted material into parts. One of the key technologies in self-replication is the ability to lay conductive circuit paths. The RepRap machine is able to lay down conductive material and an insulator. For a conductor they are using Wood’s metal, a fusible alloy that has a melting point of 158degF. To demonstrate this conductor laying ability they built the FDM head pictured in a commercial FDM machine. The project makes some reasonable compromises; it doesn’t attempt to make common items like brass bushings, microcontrollers, stepper motors, self-tapping screws, and power supplies.

UX50 Long-life Battery
|
Eliot

[
"Tablet Hacks"
] |
[] |
The Sony PEG-UX50 was an impressive package when it was released in 2003. It had a 480×320 screen, keyboard, convertible screen, built-in camera, WiFi and Bluetooth. As with most portable devices, the short time the battery stayed charged left much to be desired. Sony sold an EB40 battery pack that piggy-backed the device, but reader [JAmerican] wanted to extend its charge even further. It took a little dancing around with the charging circuit, but he was eventually able to combine 4 batteries to
construct a 3880mAh battery
that keeps the UX50 running, even after 9 hours of use. Here’s a site with a decent
photo gallery of the UX50
(at the bottom).

Proximity Card Spoofer: Proxmarkii
|
Eliot
|
[
"Misc Hacks"
] |
[] |
I had seen the link for Jonathan Westhues’s original proximity card spoofer floating around recently and decided to check out the site to see if anything had changed since we
originally covered the story
. Well, he’s got a
brand new version
. This one has far more features than the original, mostly because of the extra processing power provided by an Atmel AT91. The new spoofer can handle multiple modulation schemes; which means it is capable of copying almost any 125kHz or 13.56GHz ID-only card. Although it can’t clone cryptographic cards, it does have a full feature set for communicating with them. By connecting the USB port to a computer you can see an “oscilloscope view” of the signal from the card to assist in writing demodulation code. If you are serious about doing RFID research this hardware is a must-have. You could buy a standard reader, but that would tell you nothing about the protocol. This is definitely a clever tool and certainly impressive for something smaller than a business card.
UPDATE:
Jonathan Westhue’s work was mentioned in a CNN story Feb 14th.
You can watch the video here

MSN TV Linux Cluster
|
Eliot
|
[
"Uncategorized"
] |
[] |
I just saw this
MSN TV Linux Cluster
over on
Engadget
. The boxes have a 733mhz Celeron, 128MB RAM, 2 x USB, Ethernet, and a 64MB CF card for storage. That’s twice the RAM of an Xbox and with a node cost of $0.99 it makes a much more sensible and compact cluster. The only limit right now seems to be a 64MB capacity cap for the CF card.
You do need to build a level shifting serial cable to talk to it though. Microsoft included serial pins on the board, which is convenient. I think that a TTL to RS-232 level shifting box is becoming the second most useful device behind the
bench power supply
. You need to do serial level shifting whether you are talking to an
NSLU
,
iPod
,
GP2X
, or
WRT54G
. You might as well
make the thing USB
while you are at it. So, who wants to do the how-to?

Primary design criteria were ease of use and low cost. The original device retailed for $350 at a time when inexpensive home computers were $1000.Because the device was a dedicated web browser appliance, the cost of licensing an operating system could be avoided. The box featured such cutting-edge technology as a 64-bit RISC CPU chip, and a smart-card reader, neither of which ever caught on in the US. The web browser was compatible with both Netscape Navigator and Microsoft Internet Explorer and the box featured 2 MB of RAM, as much as many PCs. At a time when 28.8 kbps modems were common, the WebTV had a 33.6 kbps modem, and used a caching firewall for acceleration – something that most dialup ISPs didn’t offer, even as an extra-cost option, for years later. As a thin client, there was no need for a hard drive, but by putting the browser in non-volatile memory, upgrades could be downloaded from a WebTV server.”That is pretty neat. I remember when upgrades came out. Like for example, when they added cut, copy, and paste functionality- holy crap! That was the most amazing thing I ever seen :pWhat is also interesting it how much the sysreqs went up when they put WinCE on there :x",

GP2X USB Host Mode
|
Eliot
|
[
"handhelds hacks"
] |
[] |
Amongst PDAs, cellphones, portable game consoles, and digital audio players USB host mode isn’t that common. The lack of host mode is why you can’t plug your iPod into your PSP. The iPod camera connector is a partial work-around for this problem. The Linux based GP2X gets more interesting with this new development. Using the
GP2X’s USB host
requires building a special cable for its expansion port. The port features JTAG, serial, audio, and video pins as well. USB host mode opens the doors for any number of USB peripherals to be used with the GP2X: larger storage from a hard drive/iPod, full sized keyboard for use with a command line, WiFi provided by USB adapter. There is the potential to do anything that you could do with a standard PC. If I had known this I would have bought a GP2X without a second thought… so, after two thoughts I bought one and it showed up last Friday evening. I’ll let you know how it works out.

Flat Response Microphone And Amplifier
|
Eliot
|
[
"home entertainment hacks"
] |
[] |
Pete (AC7ZL) wrote in to tell us about his latest project: building a
flat response microphone and channel amplifier
. You may remember his previous project: building a
crystal radio from modern junk
. Sounds are “colored” by their surroundings; things like furniture, wall coverings, drapes and building materials all affect the way something sounds. To measure the effect that a space has on sound you need a microphone with a flat frequency response. The core element of Pete’s mic is a modified Panasonic WM61A condenser capsule. He rewired it so that it had a broader dynamic range and could handle a higher SPL at the cost of reduced gain. To boost the signal to a usable level he built a preamp with three stages of amplification. He’s got schematics and a more detailed description on the site.

"content": "A few thoughts:a) Guys- Lighten up…this isn’t rocket science…it’s simply a project for somebody interested in acoustics who cannot justify the expense of “pro” gear.b) Panasonic published a data sheet for the capsule which includes a very flat response plot from the low 20’s to over 20khz. If you choose not to believe the published specs, well, ok. What can I say? Now, it’s entirely true that the response could be altered by the capsules (mis)application, but a fair bit of attention went into addressing that. The data sheet is here:http://www.hpfriedrichs.com/downloads-projects/wm60a.pdfc) Somebody used the phrase “pristine” with regard to the tl084 capabilities or lack thereof. Input bias current, input offset current, input offset voltage, open loop gain, gain bandwidth product, slew rate, settling time, CMR, PSR, output impedance, et al, are among the parameters used to characterize an op amp. Note that “pristine” is an audiophile word, not an engineering term. I chose the ‘084 because it performs reasonably well, and is both cheap and ubiquitous. But if you don’t like the TL084, pick a different op amp! That’s the nice thing about homebrew gear. It’s what you decide to make it. :)d) Someone drew my attention to a minor error in the amp schematic. This has been corrected and uploaded to my site.PeteAC7ZL",

Geodesic Dome Shelter From Cardboard
|
Eliot
|
[
"Misc Hacks"
] |
[] |
Here are some really thorough
instructions for building geodesic domes
. This particular set of plans was developed by some Burning Man attendees who wanted a comfortable structure that would stand up to the elements. The dome is made of 30 triangles cut from double layered cardboard, 5 wood triangles with vents, 5 wooden doorway triangles, and 5 cardboard doors. The majority of the triangles are bolted together to form pentagons that are then bolted to each other. With all of the triangles painted and seams sealed with duct tape the structure is water proof. All of the dimensions and assembly instructions are provided to create a dome 12’7″ in diameter and 6’3″ in the center.
[thanks l0cke]

Power Glove Mouse
|
Eliot
|
[
"Peripherals Hacks"
] |
[] |
Feeling a bit nostalgic, Hack-A-Day reader Brandon has been
hacking on a Nintendo Power Glove
. The original Power Glove was sold by Mattel as a unique controller for the NES. It used ultrasonic sensors to determine orientation and could detect four different positions per finger. The finger’s resistance varies depending on how much it is bent, so Brandon used an LM339 comparator to determine the mouse clicks. For the actual mouse interface he used the guts of a Gyration mouse. He’s got a video of the beast in action plus links to an
original Power Glove ad
.

CVS Nightvision Camcorder
|
Eliot
|
[
"Portable Video Hacks"
] |
[] |
Our loyal reader [Everett] has hacked up a CVS single-use camcorder to
use as a nightvision scope
. This is his second prototype. The first one only had 4 cruddy IR LEDs from Radiohut and a front mounted battery pack. For the second one, he separated the batteries from the camera. He removed the IR filter from the CCD and added 8 higher quality IR LEDs. On the backside of the camera is the eyepiece from a Handycam. It keeps the the LCD screen from leaking light and has a lense to help the eye to focus on the screen. The LCD is to bright to use without adding a dimmer pot. The camera is mounted to a headlamp rig with the batteries on the backside of the head. It may not have the best image quality, but at $35 you can’t go wrong when it comes to nightvision fun.

I can build anything out of steel and fiber glass. Then Id give it a camo paint job. Just to make it look cool. Creating custom parts isent hard if you have the materials and the tools. Not to mention the know how to do such a task. And a tip for getting a great looking paint job, Take the parts to a professional shop. They have the expertise and the skill to paint the pieces beautifuly. You may spend a bit of cash. But then again, if its to have a reputation as a modder and a hacker, isent it worth it.",

DVD Thermometer

[
"Misc Hacks"

[] |
Reader [alberto ricci bitti]’s
DVD thermometer
is a temperature sensing infrared remote that controls a DVD showing the temperature. Since the box doesn’t get any feedback from the DVD player, it stops and starts the disc to make sure it is at a known state. The brain of the device is a Motorola MC68HC908QT4, an 8-pin microcontroller. Communication with the Maxim DS1621 temperature sensor I2C bus is done in software. Even if you don’t want to build a gaudy thermometer the article features a lot of interesting information. It covers reverse engineering the remote, emulating an I2C bus, and creating a programmable pulse generator instead of bitbanging.

Hack Media: Security Podcasts

[
"Uncategorized"

Do you want to listen to four and a half hours of security podcasts? Well, you don’t have to because I did. Here are the highlights from podcasts released this last week:
Security Now! #27 How Local Area Networks Work, Part 1
37:09 If you don’t know the difference between DHCP and static IP, then this is the podcast for you! Next week promises to be a little more interesting when they get into the problems with ARP.
CyberSpeak Feb 18
76:36 has some pretty good news coverage, but the real highlight is the interview with Bruce Potter from
The Shmoo Group
that starts after 20:00. If you don’t know about the group and the work they’ve done, this is a good intro.
LiveAmmo: Digital Forensics and Hacking Investigations, Part 2
46:54 Woof. If you are persuing digital forensics as a career then this would be a great start. Otherwise, avoid, unless you want to know what particular subsection of a law you are violating.
SploitCast #006
36:26 probably has the best atmosphere of these podcasts (and it’s the shortest). The team covers the recent news of a
phishing site using a valid SSL cert
. You could probably wait till next week when they talk to
Lance James
to get all of the details. I will say that the Web 2.0 discussion is about as inane as arguing which year the millennium starts. They do earn some extra points since my mom doesn’t read
Schneier
.
Blue Box #16
69:00 is all about VoIP and naturally the best produced. I don’t follow VoIP very closely, so the news roundup for the first 20 minutes was really interesting. If you aren’t doing enterprise VoIP then this podcast isn’t for you.
Each of these had some high points (even LiveAmmo). They could all do better if they were shorter. I would say that CyberSpeak was my favorite this week, but I don’t want to encourage another 76 minute podcast. What podcasts do you recommend?

Low-cost Sensing And Communication With An LED
|
Eliot
|
[
"Misc Hacks"
] |
[] |
LEDs are extremely common in electronic devices. They are used as light emitters, but can also be used as light detectors since they are photodiodes. By quickly switching between light emitting and detecting, you can use the LEDs to determine the ambient lighting and even do bidirectional communication. MERL has a good paper covering the basics of
how this system works
and how they used it as a “last-centimeter” communication device. The system can be implemented using one LED, a resistor, and two I/O pins. So, it could be used cheaply in almost any device. The microprocessor quickly switches the LED between emitting light, detecting light (LED acts as a charging capacitor), and measuring the discharge rate of the LED to determine light level. Jeff Han has a neat
video demo
of how this system can be used as a proximity sensor.
UPDATE:
[hawkeyeaz1] pointed to a blog covering
one person’s investigations into LED sensors
.

The Multi touch display works by frustrated total internal reflection, but requires a camera on the back. Why not use LEDs on the edge (like the MT-FTIR suggests –http://mrl.nyu.edu/%7Ejhan/ftirsense/index.html) but a mirror on two edges so the sensors can sense when something touches the screen (causing a dark spot where the light is reflected down, not back at the LED)….

I guess it would be a cool way to replace your pressure sensative tracking surface on your mouse, or it could make a neat tablet, but from a cost standpoint it just plain isn’t economical to mass-produce. Sure, it’s cheaper then BUILDING your own pressure sensative tablet, but it isn’t cheaper then BUYING one. And is this even all that accurate? Sure, it has loads of pressure layers to be abused, but you would need alot of little LED’s arranged in a dense manner just to get what you want, and even then, you have a bright red (or whatever color you choose) light.I guess if you manipulated it in such a way that you could use this to add real hand gestures to your computer it would be cool and cost effective since there is no real product out on the market for that, but in comparason to all of the current interface devices it isn’t all that great.Don’t get me wrong, it’s cool, it’s neat, and if i had the time i sure a hell would do it myself, but it isn’t practical, atleast for the time bieng.",

It responded to hand gestures on or near the glass that allowed you to move, rotate, and zoom the map. considering I didn’t see anything in the apparatus outside of the Projector and the LED arrays (both plugged into a PC) I wouldn’t be surprised if the LEDs were being used in a similar fashion to collect the hand gestures.",

Hacking The Commodore 64 DTV Version 2
|
Eliot
|
[
"home entertainment hacks"
] |
[] |
The original C64 DTV was a joystick containing 30 games sold in 2004. It attracted hackers because it could be modified into a fully functioning console. The latest version of the chip is being sold
inside a Radio Shack Hummer game
. This version fixes bugs in the original and adds several features to improve memory access and CPU speed. Before you get started there are several modifications that need to be done to improve the video and audio quality of the system. Once these mods are complete you can start playing with the machine just like an original C64. Oh, the Hummer game will look a lot better too.

Vik Olliver gave a presentation on the
RepRap
project to the
AuckLUG
last week. You can
download it from the Internet Archive
in Ogg Theora format (which will keep us from trashing AuckLUG’s archive). If you’re interested in this project, you should be reading the
RepRap blog
, which is getting updated daily.

So, time will tell if they can make the machine a reality.Another thing is, the demonstration in the end is totally useless and stupid. The guy made the whole talk and demonstrates how to melt ABS plastic with a heated filament. This is totally ridiculous. Its like a scientist giving a very overly ambitious talk on how to cure cancer and finally “demonstrating” how he uses a needle on a patient.My opinion for now is, they are just a bunch of random people with a random idea, and no real designs/plans.May be i should start giving out talks on how I will concieve a time machine.

"content": "Hi,Just found the site, and thought I’d clear up some of the confusion. First off, we’re about 5 months away from producing any kind of recognisable artifact. The prototype circuitry used to drive the demo was knocked up in a hurry for LCA2006 in January, and the team has been developing a more modular system that enables multiple devices to be driven off a single USB or serial port. It’s a handy system in its own right.The demonstration at the end was totally ad hoc and unplanned. I’d only finished building the new extruder the previous day. The palstic melted was CAPA 6800 or Polymorph, not ABS. There was not enough filiament to demonstrate how well defined the starting and stoping of the flow is – an important aspect for acturate deposition. The consistency of flow was demonstrated quite nicely though.A full, fabricated 3D axis for plastic deposition now exists, and currently sits motionless in my workshop while I finish a few more stepper driver boards. The full plans and CAD files – ready to load into an FDM machine – are on the reprap.org website.There are 5 main variants under construction for a range of purposes, from the simple 3D axis I’m working on to a sophisticated 6D Stewart platform. The designs are being done in a modular manner, and the best aspects of all machines will be combined for the 1.0 release. Stay tuned!Vik :v)",

Ball And Plate Doohickey

"Misc Hacks"

So, if you were wondering what [Kenn Sebesta] was working on that needed
yesterday’s hack
,
this is it
. The plate can maintain the cue ball in its current position or make it travel an arbitrary path like a circle or figure-eight. It can also avoid obstacles placed on the plate. Kenn has documented his project thoroughly and covers many of the problems he faced along the way, like
how to find the ball in the webcam image
. Like most quality thesis projects, it’s constructed out of LEGO.
UPDATE:
Now with video

Now, I can more or less throw the ball on the table and it’ll catch it. Even better, I can stabilize one pool ball, careem another pool ball into it– knocking off the first– and the computer will simply stabilize the second ball!",

AccelR8, A Homemade G-meter

[
"Transportation Hacks"
] |
[] |
Jesper has created an
automotive performance meter
using a handful of ICs. The key chip is the ADXL202 from Analog Devices. It measures acceleration while the AVR 8515 keeps track of time and does all of the calculations. All you need to do is enter the weight of the vehicle and the meter will calculate your 0-60 mph time, 60-0 braking distance, and maximum horsepower. There is a complete schematic on Jesper’s site, but the code still needs to have a few bugs worked out. This project is essentially a reproduction of the first generation
G-TECH/Pro meter
(bunnie has a
picture of the original board
). The new generation G-TECH meters are fun to play with and do interesting things like determining the engine RPM by measuring the noise in the electrical system.

3D Board Modeling With Eagle And POVRay
|
Eliot

[
"Misc Hacks"
] |
[] |
Sometimes the two-dimensional layout of a circuit board doesn’t tell the whole story so Matthias Wei?r created
Eagle3D
. Once the board is laid out in
EAGLE
you export it using the Eagle3D tool. The tool has predefined parts that it then uses to render the board in 3D using
POV-Ray
, a free ray-tracing program. There are a lot of parts included already, but you can define more using POV-Ray’s Scene Description Language. Using POV-Ray you can also make 3D movies your board

Air Cooled Mouse Pad
|
Eliot

[
"Peripherals Hacks"

[] |
Jared and Dan from Inventgeek have just posted their latest how-to:
The air cooled mouse pad
. They know that there are air cooled mice that you can buy, but why should you have to use an inferior mouse for gaming just for one feature? They decided instead to convert an Antec laptop cooler into the ultimate gaming mouse pad; One that keeps your hand cool and lets you use whatever mouse you prefer.

"Mac Hacks"

Hack-A-Day reader [Lee Olivares]
stuffed a Macintosh Plus full of new hardware
without butchering the case. From the original test fit he could see that the Mac Mini’s DVD slot lined up well with the original floppy slot, so it just needed to be widened a little bit for clearance. The monitor is black and white, but a separate VGA port has been split off for an external monitor. The original motherboard was cut down so that the original power switch and ports could be used. Any new ports were hidden behind the battery cover.

FON Or How To Get A Cheap Linksys WRT54G
|
Eliot
|
[
"Uncategorized"
] |
[] |
FON
hit the news recently because it acquired some
venture capital from Google and Skype
. Its goal is to create a global network of access points run by home users. The users can either offer access for free or resell their bandwidth. The actual FON software is based on
DD-WRT
, a Linux based firmware for the Linksys WRT54G wireless router and others. DD-WRT features a captive portal, QoS, and many additional features. FON is selling 3,000 routers with their software pre-installed for 25USD/EUR plus shipping. This is a great way to pick up a WRT without paying Linksys’s
Linux penalty
and it comes with a great firmware already installed. Oh, unless you have broadband from a friendly company like
Speakeasy
, becoming a fonero is probably a violation of your “terms of service”.

"content": "The link isn’t dead, and isn’t a joke.As of v5, the wrt54g hardware has changed so that existing linux firmware (dd-wrt, openwrt, etc.) won’t work. To help “support” the linux folks that still want to use the old platform, there is now a wrt54gl (L for Linux) that will probably be harder to find and more expensive.Not only is it more expensive, but don’t expect the same rebate offers as the wrt54g..Cisco/Linksys should be given some credit for supporting the Linux community in this way. I can understand their motivation to lower hardware costs on such a popular product (they ARE a business..) However, I hope it that they use linux in the future and aren’t running to proprietary OSes to avoid having to deal with the hacker community.",

I might even set that one up just for the fon service if I feel like it.",

"content": "ive been working with some friends to create somthing like a internal network with wifi that connect to each other across the state. We felt we were tired of the cost of the internet and started on own internal version.Some have their own web servers and share with many people and some have database servers dns servers and so on. And the nice point to it all if your within range of our netowrk you can connect for free none of us charge or use any type of advertising. What we would like to see is a setup that connects wifi from state to state so everyone can have free wifi type internet and try to get away from this governed type of crap.What would be nice is to setup a website to get as many people interested in this as we could. I have several gigs of space on several servers. And would be more then glad to give someone space to create a site or what ever they need.Instead of the internet we could have like internet3 where we control it and we have say so of whats on our systems and can give all this away for free. So everyone could enjoy.",
