Build Your Own GPS And GLONASS Receiver
fabienneserriere
[ "gps hacks", "Misc Hacks", "Wireless Hacks" ]
[ "analog", "glonass", "gps", "HamRadio", "packetradio", "pkt", "radio", "receiver" ]
[superlopez] sent in 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 . permalink

Last night I rebuilt my ECM Giotto with a new boiler. I’ve seen PID controlled machines before, but today I stumbled across 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.) permalink

Remote Control Your Blinds

[ "blind controller", "BlindController", "x10" ]
I was dredging my brain for interesting topics to cover and this vertical blind hack popped into my head. The page isn’t the prettiest, but it’s the hack that counts. 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. permalink

[Nick] caught [Alex]s GPS enabled AVR , so he sent in his project using the same Telit GM862 module. Rather than depend on an external AVR, he wanted to use the on-board python interpreter. Apparently, documentation is a bit sparse, so he put together a good write-up on developing python for the device. Since the GPS unit takes up the com port previously used for debugging info, he added a hardware python debugging board to speed development. permalink

ATLAS Powered Rope Ascender Gen 3

[ "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. permalink

I wasn’t going to post this – it’s a freakin phone after all. But I’ve gotten quite a few tips on it, and I’d like them to end. [George] made a concerted effort to hack the iPhone – and it paid off. After his crazy 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. permalink

[ "Cellphone Hacks" ]

Steve Schear and David Hulton gave a presentation on A5 cracking. A5 is the encryption employed on GSM cellphone networks between the handset and the tower (nowhere else in the network). To sniff the GSM band, they use the GNU radio 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 . permalink

It’s well worth your time and will give you an idea of the broad slice of info that’s covered at the convention. That picture is him repruhzenting for Hack-A-Day in Fast Company magazine. Update: I’m finally getting caught up on my RSS feeds; check out Richard Bejtlich’s equally good summary of Black Hat: part 1 and part 2 . permalink

I’m pretty happy with our skybox event. [Eliot] and I’ve both got a good pile of stickers to give away, so ask us if you want ’em. It was great turn out for all the shirts we gave out. Thanks to [Eliot]s g-string water bottle, we raised $263 for the EFF. [Eliot]’s heading to CCC later, so hit him up for stickers while he’s across the pond.

I got quite a few emails about this, but didn’t have a chance to check it out until now. It seems that the feds have been raiding various mod shops and individuals who’ve been doing mods for others. I’m a fan of open, moddable and repairable hardware, so this is sad news to me. There’s a first hand account from one of the raided individuals along with a decent commentary on the issue sent in by [xantium]. This might sound a bit strange, but take the time to let your congress critter know what you think about this issue. Don’t expect them to understand the technical background, but letting them know that you’re unhappy with the execution of the DMCA and that labeling legitimate uses for mod-chip technology as illegal is the equivalent to outlawing home car repair might make a difference.

I made it over to pre-registration earlier and scored my badge. It’s a pretty interesting piece of work by [kingpin]. It’s got 95 SMD leds forming a matrix display. The top and bottom icons on the badge are touch sensitive buttons. It’s got selectable modes, programmable text scrolling, a pre-set POV mode and adjustable scrolling speed. Update : I started digging through the CD they’re handing out at registration and found the schematics, BOM, layout, everything. I’ll have it posted as soon as it finishes uploading over my evdo connection. The board has provisions for wireless, 3 axis accelerometer, serial interface and it’s using a Freescale QF16 processor. (I tried looking up the chip number earlier, but utterly failed) Update 2 : I’m putting interesting defcon files up here . All the badge info I have is online. I noticed a confidentiality notice on one of the files, I’m assuming that it’s ok to distribute since they’re distributing this freely on the conference CD. If I hear otherwise, I’ll have to pull it. permalink

Black Hat 2007 Other Wireless

[ "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.

Black Hat 2007 Premature AJAX-ulation
Eliot
[ "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.

[ J0hnny ]’s at 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).

How To Overclock A Casio Fx-9750G Plus
Will O'Brien
[ "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!

Just stoking up a bit for Defcon 15 later this week. [Eliot] and I’ll both be there. My personal coffee stash is down to a single selection of Ethiopian Yirg, so I probably won’t enter the coffee wars . (But I might stop by and add some Hack-A-Day swag to the pot for the winner.) The final speaker schedule looks really good. It’ll be difficult to decide which talks to visit. The DefconBots event should be interesting. I’m hoping to see some original hardware creations. Looks like wireless cracking is still one of the most popular topics. Hack-A-Day friend [Aaron] of Midnight Research will be presenting the latest on wicrawl . Oh, and just prior to Defcon, the Pwnie Awards will take place at Black Hat . See you in Vegas!

Defcon 15: Exploiting Authentication Systems
Will O'Brien
[ "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.

[King Tuna]’s Hacking EVDO was a popular talk. Things are really just starting on this front. Now that some of the newer cards have unlocked firmware (probably thanks to the need for sofware update EVDO revisions), It’s now possible to edit the firmware. With the door open, people can start mucking around with ESN’s and we’ll probably see some ESN duplication exploits soon.

I’m guessing this was pretty widely reported, but an NBC undercover reporter fled after being outed in the opening session. NBC Dateline associate producer Michelle Madigan refused press credentials on four separate occasions, choosing instead to pose as a normal attendee in order to covertly film other attendees. 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 “ To catch a predator ” style.

They managed a 45 second run at one point, and used a simple electric blower to evacuate the beer from the cooling line. They found that it was a bit easier to just blow it out the old fashioned way.

Mecha Turbo Crazy Coffee Roaster
Will O'Brien
[ "Misc Hacks" ]
[]
I’m a wee bit of a coffee geek . 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. permalink

[XanTium] sent this in a few days ago, but I thought you guys would dig it. Here are the details straight from his email: 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.)

[Christoph] sent in [fingers] rather interesting coffee hacking project . (Use the fish to translate it to English .) Using various scrounged parts, he’s constructed his own automated french press brewer. A good french press is a bit of an art, so I can understand the desire to automate one. 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. permalink

This little how-to was sent in by [Ed]. The sound dock posts get quite a few hits, so I figured I’d share. 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.

[B-Rock] sent along a little iphone sim testing performed by our buds over at tuaw. If you’re trying to develop web content for the latest in geek swag, you might dig firebug for the iphone.

Maybe you didn’t have a crazy physics teacher, or missed [Mr. Wizard], so you might not have seen the hot dog cooking by electrocution. There is one new idea this time – stick some LEDs in your victim . Thanks[ Matthew] If that’s not geeky enough for you, check out this simple ibook server mod sent in by [Jonas]. permalink

Make Custom Dash Mods (ipod Dock)

[Daniel ] sent in this one , 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. permalink

Remember reactable ? (Or the iphone interface) As I recall, there were some comments noting build difficulties. [Gil]let me know about a nice how-to on building your own multitouch display. It’s not a reactable, but it’ll probably easier to re-create on your own. It looks like it was probably written by the tinkerit guy(s). permalink

Vacuum Bike Pump

[drcrash] sent in this thorough how-to on converting a cheap bike pump to pull a vacuum. Apparently it’s just the thing for small vacuum bagging projects. I’m thinking that this could be combined with a low rpm motor and a pivot. Just picture an old steam locomotive wheel drive, and you should get my idea. (A windshield wiper motor would probably be perfect.) permalink

DIY SCUBA: Death On A Stick

Sorry guys, I’ve got to comment on this one. [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.

[sprite_tm] sent in this 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. Thanks for the tips guys, keep em comin. permalink

Despite digital mixing, some guys just love their old turntables. TerminatorX has one concept: allow users to scratch music like it’s on vinyl. Some guys hate using their mouse for it, so they’ve been connecting mice to their turntables. Some use belt drives, other use optical sensors up top. Thanks to [Dylan] for the tip. permalink
