this detailed article
(mirrored
here
and
here
) which describes how to build a GPS and GLONASS (the Russian version of GPS) receiver. The resulting device is gigantic compared to one of those
tiny
bluetooth USB GPS units, but the ability to build one’s own receiver is one of those post-apocalyptic skills I sure would like to have. The creator of the article [Matjaz Vidmar] aka [S53MV] also has pages on
Packet-Radio
(PKT) transceiver improvements (
PKT
gets my vote for the best post-apocalyptic technology, and the only believable technology featured in the Transformers movie), and a more sophisticated homemade
frequency counter
than the one featured
earlier
this summer.
In 2005 we featured a
from-scratch GPS receiver
as well, thought the project site seems to be down. If your GPS unit just needs a better antenna, check out [Will]’s
how-to from last year
.

this
modded Rancillo Silvia. [Tim] replaced the internal brain with a PIC controller, added a NES control pad for input, a VFD display and a custom laser cut acrylic top. He used the PIC to provide PID control and PWM heater control with the usual solid state relays. I was leaning towards using a PIC for PID control myself, but then I scored my Giotto. (The heat exchanger and larger boiler makes it a bit of a moot point, but I’m still tempted to add PID boiler controls.)

The mechanism is constructed from PC board. A motor fitted with a ball chain drive gear pulls the chain in either direction. When the end of travel is reached, a micro-switch is triggered by the stand off that’s actuated by the chain. The motor is driven by a pair of relays that latch to form a simple direction control. When power is triggered on or off, the motor starts moving until the stop is triggered.

I think it’s an absolutely excellent piece of work. He’s offered to post more technical details if we have enough interest – It’s got my vote.
The video (after the break) starts off a bit dry, but trust me – it’s worth checking out. The monitor sports a TI MCU, bluetooth chipset, flash socket, multiple signal amps and onboard audio amplification. The PocketPC is showing the real time data stream being delivered via bluetooth.

"Misc Hacks"
] | [
"ascender",
"atlas",
"military",
"rope"
] | This last weekend we got a chance to check out
ATLAS Devices
‘ latest version of their powered rope ascender. You probably saw their
first generation device
in the news earlier in the year. It was originally built for a design competition, but they’re now on generation 3. The earliest version used a capstan style winder, but newer versions have a far more simple/elegant design. The original had a ton of thrust and needle bearings that were hard to keep in adjustment. The new design is lighter, less abrasive to the rope, and easier to use.
Rigging the device is fairly straight forward; you could probably figure it out without any instruction. We attached a standard climbing harness to the device for our ascent. An additional rappelling rope was used as a backup.
It’s a simple device to use. You just flip the large toggle switch to “on”, pull the small trigger and off you go. The original unit moved at 10ft/s, but it was almost too jarring. The newer unit has a much higher load capacity. To descend you squeeze the large metal brake release handle. This causes you to drop fairly slowly since the electric brake is still engaged. The solution is to turn off the machine and regulate the descent with the handbrake.
Right now they’re in the middle of doing a short production run that will be evaluated by the military. In service, a squad would have one person climb the obstacle. The next person would use the ascender and then just keep the ascender at the top to pull up the rest of the troops… I’m guessing they won’t be using it to peep second story windows like us (no, not really). While the method of rope engagement is pretty much finalized, the team is constantly trying to improve the motor and battery efficiency.
We’d like to thank Nate Ball and the rest of the ATLAS Devices team. Your next chance to see the ascender in person will be
Wired’s NextFest
Sept. 13-16th in LA.

ebay auction
that topped out at 99,999,999.99 last time I checked, he ended up trading his first phone for a Nissan 350z and a few more iPhones.
He documented his process, step by step – if you’ve got the skills, you can probably do it yourself. The soldering work is damn fine work – probably the hardest thing there is. The write up is a little hard to follow, so plan on taking some time to comprehend everything. (Blogging software isn’t the best way to organize how-tos, trust me on this.) My hats off to [George], he did some great work. – So, why didn’t I want to post it? All this work yielded one thing: carrier choice for the iPhone.

USRP
.
GNU radio
is a software defined radio project, which given some effort you should be able to both receive and transmit in any RF band. You could use it to broadcast digital television, track radio tags, or even mess with garage door openers. For their initial investigation they used a Nokia 3310 in trace mode to dump the initial frames. Using a box with at least 27 FPGA’s they plan on constructing a 6+ terabyte rainbow table (it’ll take a couple months). Once complete, any GSM conversation can be cracked in less than 5 minutes using a single FPGA. The Hackers Choice has more info on the
USRP based GSM analyzer
and
what they did to crack A5

"cons",
"Peripherals Hacks"
] | [
"keyboard",
"mouse",
"wireless"
] | Luis Miras presented “Other Wireless: New ways of being Pwned”. Instead of common con topics like Bluetooth or WiFi, this dealt with the cheap radios used in wireless keyboards, mice, and things like the wireless remote pictured above. These RX/TX pairs are found in 27MHz, 900MHz, and 2.4GHz versions. The devices all use the same main components: a microcontroller, an EEPROM for storing the serial number, and the transmitter. The dongle is nearly the same only with a receiver.
Luis began reversing a Kensington Wireless Presenter by first visiting the FCC website. All radio devices have to be evaluated by them. Just type in the FCC number on the bottom of the device and in some cases you might even get a full schematic. He could then grab datasheets for the radios. By adding your own microcontroller you can send arbitrary key presses to the dongle or you could tap the RX side and easily create a sniffer. To reverse the protocol though you’ll need an
oscilloscope
or even better a
logic analyzer
.
He demoed a replay attack: sending the page up command repeatedly. Unfortunately the hacked wireless presenter doesn’t have a full keycode space so you can’t send it arbitrary keystrokes. Luis still needs to break the wireless keyboard encryption scheme in order to create a useful key sniffer though. | 8 | 8 | [

"cons",
"Misc Hacks"
] | [] | Billy Hoffman and Bryan Sullivan from
SPI Dynamics
gave one of the more entertaining talks today. The title is an allusion to peoples willingness to apply new technology before they fully understand it. Instead of laughing at silly web 2.0 developers they decided to build their own AJAXified website by consulting the resources that any programmer would: AJAX books, blogs, and forums. What they ended up with was hackervactations.com… a security hole riddled gem built on good intentions.
For their presentation they demonstrated how easily you could hammer on the site using something like
Firebug
. Any piece of code on the client side can’t be trusted. You can throw in a break point anywhere and manipulate any variable. So if something like the ticket price is stored locally, you can modify it before it gets debited. We learned long ago not to do this in HTML forms, but it’s the same problem all over again disguised by new technology.
Another common practice is dumping all of the functions into one common.js file. Find something like an admin function and you can call that from anywhere. You could also create a race condition. Say one function adds an item and updates the cart total; the other debits your account and ships the order. If you call the two functions with a slight offset you could interleave their actions: add an item to your cart, debit the 0 total from your account, update it with actual total, and ship the item.
Their last example involved trusting the client to do final data formatting. Using two GET requests they were able to dump the entire database. In a JSON object they could add as many SQL queries as they want without having to worry about matching the number of arguments like you would in standard injection.
There were a couple final thoughts: These problems stem from putting too much trust in the client. That doesn’t bode well for offline technologies like
Google Gears
where everything has to be on the client or
Silverlight
which makes it difficult to know whether your code is going to the client or the server. Lastly, if you’re worried about premature AJAX-ulation, abstinence may be the best solution. | 5 | 5 | [

Blackhat
and
Defcon
this year with his talk on “No-Tech Hacking”. It’s a fun talk that boils down to this: loads of information can be gathered using low tech methods. A small digital (or film) camera is ideal for shoulder surfing, identifying weaknesses, and assessing strengths.
The talk is pretty amusing – the commentary on the example shots is priceless. The concept has gone over so well at the cons that [J0hnny] has contributed a chapter to a book on risk management. You can grab a sample chapter
here
. It looks like he’ll be running his talk at 8pm on Friday at Defcon. From the sample chapter, I’d say that the book should be pretty good. It looks like a good introduction to social engineering and using your wits to defeat obstacles (like corporate security). | 9 | 9 | [

"Misc Hacks"
] | [] | [Visceroid] could only find overclocking resources online for TI calcs. He spent some time under the hood of his casio fx-9750G plus and sent in a write-up for us. I gave it a quick edit, but here it goes:
I opened up the calculator, which reveals the board with the processor on it,
with the RAM, ROM, CPU and a few other surface mounts visible.
The graphics are underneath and the buttons are also underneath on an underlying board.
The main batteries, backup battery and serial port are connected on the underlying board, and I also have access to them.
The board with the CPU is in the upper half, allowing the lower half of the underlying board to be revealed. The CPU is a blob of epoxy, and the RAM is a product of BSI. Don’t know what the ROM is yet.
There is a small surface mount crystal beside the CPU, 3 pins, with a resistor in parallel to the outer two pins. It’s just a small rectangular prism thing. The center is ground, and the outer two are the crystal. I unsoldered the crystal and used some thin flexable wires to extend it. The original crystal is reasonably hard to unsolder, but it’s worth it.
I made a hole in the side of the battery compartment, just above the backup battery.
The perfect place to put
hack
switches. I found a DPDT switch (actually has 4 poles though, but only need 2. Might use one of the other ones as an overclock indicator later) and soldered the wires from the CPU to the middle so you can toggle between the two crystals.
I connected the original crystal to one side of the switch, and a new 8MHz crystal on the other two. I insulated the bigger crystal to stop it from shorting. The bigger crystal is one of those plain big 2 lead crystals used in many microcontroller projects. I guess a resonator would also be acceptable too.
So basically, it’s a DPDT switch which toggles between the original crystal and the new faster crystal, located somewhere useful. It’s a good idea to have it switchable, because it means EVERYTHING is faster, so you’ll need to switch back to normal for serial communication.
I don’t think shielding is neccessary for the long wires. Some work is needed though to get everything fitting nicely. I am still having a bit of trouble that it is very tight fitting. one edge doesn’t close quite as much as it’s supposed to. But at least it works.
Some words of advice:
BACKUP YOUR DATA
and also make sure there’s no power on board just in case.
2 times as fast
4.3 MHz to 8 MHz
probally uses more battery power though
you might get away with going higher, although I don’t recommend it. It’s probally going to make the CPU quite hot or just simply damage it. Maybe you could put a heatsink on it. The epoxy blob also means it’d be quite hard to sink the heat.
sorry if it’s a bit too descriptive!
In the future, I hope to do a ROM
hack
and allowing me to select between the original ROM and my own custom system in an EEPROM. That will come much later though. It is really hard to find this sort of information on the internet! | 13 | 13 | [

"cons",
"Misc Hacks"
] | [] | [Zac Franken] gave a good talk on authentication systems. (Card readers, biometric systems, etc). After a good introduction to various access control systems, he demoed an excellent exploit tool. Rather than focus on the access mechanism, he exploited the lack of reader installation security. Most card readers are secured by a plastic cover and a pair of screws. Inside, the reader wires are vulnerable. [Zac] put together the equivalent of a keyboard sniffer for the reader wiring. With this little device in place, he was able to collect access codes and use them to exploit the reader authentication system.
The operation goes like this: Install the sniffer. Let it collect some codes. On return, [Zac] is able to use his own card to become a pseudo authenticated card owner, restrict and allow access to other cards. That’s it. No sneaking up behind people to read their cards, just a few minutes with a screwdriver.
He’s not releasing the design, simply because measures to prevent this type of intercept/control mechanism would be extremely costly. | 34 | 34 | [

fled after being outed

Defcon has a long running tradition of playing”spot the fed”, where attendees out people they think are federal agents. The feds play along and it’s all good fun. This was entirely different though: the game “spot the undercover reporter” was announced and she fled immediately, only to be filmed “

They found that it was a bit easier to just blow it out the old fashioned way. | 6 | 6 | [

This
roaster was built by [farmroast]. It’s a highly modified of version of the roaster that
I’ve been using
for the last year or so. A convection oven up top provides the primary heat source, while the beans are spun around in the roast chamber below. A pair of thermocouples let you know what’s going on inside the chamber. When the roast is done, pop the top, dump the beans into the drawer, and a fan mounted below cools them to room temperature in about a minute. It was put up for a home roaster building contest – You might be interested in the
other entries
.
I hope the coffee wars at defcon are this interesting.

"Xbox Hacks"

Hackers on the XBH forums managed to change DVD key and Game Region Code in the Xbox 360 ‘Key Vault’ (that stores on flashchip: console certificate(s), per-box private keys, DVD key, however NOT any code-related encryption keys).
However you should know the ‘Key Vault’ is encrypted with the per-xbox360 ‘CPU key’, so that means this
hack
is only possible on Hypervisor exploitable Xbox360s (kernel 4532 and 4548) for now. You will of course also have to read/flash the Xbox360 flashchip (by desoldering it and read/flash it with programmer or for example use the versatile Infectus dev chip)
You can read up on some more details
here
or get a login and check out the
actual forum thread
. The end result: play EU games on your US 360. (It doesn’t sound like the DVD movie region has been successfully changed, but modded DVD players are easy to make.) | 7 | 7 | [

The grind itself isn’t too critical, but brewing time can vary with the roast and grind of the bean. Personally, I’ve found that decent brew temperature is the real key to a good press. [Fingers] machine provides a way to do everything consistently, but the custom aluminum brew chamber might be effecting the brew temperature.

– and I agree. It’s an open gaming platform built around a PSP LCD. It’s got all the basics, and it’s expandable. They’d like to put together an order for a run of boards, so let em know if you want one. If you’re lazy, here’s the specs:
MX21 ARM9 266MHz processor with 64MB SDRAM and 16 MB of FLASH
TFT LCD from the
PSP
(our thanks to Nathan at Sparkfun for helping us out with that)
stereo audio CODEC
stereo speakers
headphone jack
microphone
couple of joysticks
loads of buttons
battery pack
SD/MMC slot
expandable (can add
GPS
,
bluetooth
, accelerometers and gyros, etc…)
Most of the hardware is pretty decent, but the battery pack could use some help. Maybe a good surplus li-ion cell phone battery.

It’s a nice simple, solid design – and you’ve gotta love the thumb screws. (I’m not sure how a more efficient PWM regulated power source would affect the audio output)

It combines six video channels and uses acoustic frequencies and tiny but simple looking transducers to vibrate the crystal that channels a laser to generate the hologram.

There is a solderless way to
hack
an aux input for the Sounddock.
(1)Go to Wal-mart (or elsewhere) and buy the Griffin Dock Adapter for iPod Shuffle (~$20) and a Belkin Speaker and Headphone splitter (~$4). (The Belkin splitter is needed in order to fit properly over the Shuffle plug on the device, but other cables/adapters might work.)
(2)Remove the existing adapter plate and replace it with the Dock adapter.
(3) Set the switch to speaker. (Very Important!) (4)Plug in one end of the Belkin adapter and you are ready to go! Any input signal automatically activates the Sounddock. Now you have a fully functional female and male stereo headphone input for your Sounddock.
–>Total cost ~$25 and no soldering required. | 11 | 11 | [

, from an O’Reilly book, it’s older but the results are just stunning. The iPod dock has been done countless times, but the really interesting part is the custom dash molding technique. The cradle was mocked up with clay on the original piece, then a silicon mold was cast from the mock up. After that, the entire piece was re-created inside the mold. After some dremel work and a bit of sanding, it came out beautifully. It looks like a great way to make custom LCD/GPS dash inserts.

[tylin] sent in this “DIY SCUBA” youtube video. These guys used a home shop air compressor with a particle filter so they could “SCUBA dive”. This kid is lucky he didn’t die.
I guarantee there were impurities in the compressed air. A major concern here is carbon monoxide, among others. That filter they used is designed to reduce particles, not scrub out CO, CO2, etc. Hemoglobin loves CO even more than dear old O2, so he could have asphixiated or suffered from convulsions despite having an air supply.
He’s lucky he didn’t blow his lungs out. The second he took a remotely full breath off that hose, he started to float up. If he happened to hold his breath it would have ruptured his lungs and caused all sorts of nasty problems.
He wasn’t wearing a weight belt – furthering the risk of floating up when he took a breath. (in my experience about 90% of people are positively buoyant)
4)Nobody was in the water watching his back. If he’d suffered any complications, no-one was there to make sure he didn’t drown. (Think convulsions, black out, etc)
Sorry for the rant – but this is just effing stupid. Don’t try this crap, ever. I’m an advanced open water diver
myself
– get training and real equipment.
Update: The video was removed after reading my response to it. I went ahead and puled the youtube link since it’s useless. | 61 | 50 | [

nice little single AA battery micro-controller power hack. He’s using the uc to generate a PWM signal for a simple voltage step up circuit – the catch is that the controller has to start working before it can generate the signal. He came up with a nice little solution to this caveat – a push button start that gets things rolling once the coil charges up.
