T-Mobile SDA Unlocking, Overclocking And Skype
Eliot
[ "Cellphone Hacks" ]
[]
[Ken Keiter] has written up a guide to unlocking your T-Mobile SDA, overclocking it, and then adding Skype for use over WiFi. The unlock procedure is pretty simple and only needs some free software. The overclocking is just as simple. The OMAP processor needs to be overclocked to 240MHz otherwise Skype will have a lot of lag. The Skype install is straightforward except for one hitch: the phone doesn’t have a touch screen so you can’t click Sign-In. You can get around this using a piece of software called Pocket Controller which lets you click the button with your mouse. After that you can set Skype to auto sign-in so you’ll never need to use the mouse again. Ken’s final tip is how to change the T-Zones button so that it launches Skype. permalink

Optically Isolated Parallel Port I2C Adapter

I2C is a simple communications bus similar to 1-wire, which we’ve talked about earlier . [hnch] has built a really simple I2C parallel port interface . It’s optically isolated so you don’t have to worry about a mistake frying your computer. I2C modules already come with the Linux kernel. It will even treat temperature sensors you attach exactly like the ones you have on your motherboard so you can monitor them using ordinary software like gkrellm. There are lots of other devices that use I2C as well. [hnch] has a nerdity gallery and will gladly write up any other project you’d like information on. permalink

Master modder ZapWizard has completed work on version 3 of his home built powder coating gun . Powder coat is applied using air pressure to blow negatively charged thermoplastic particles onto a grounded metal surface. The metal part is then baked to make a hard finish. ZapWizard’s gun uses an air pistol with regulator at the bottom operating at 15 PSI. The powder is held in an acrylic kitchen canister with a reinforced seal. The final element is an ionizer element placed in front of the discharge nozzle. Version 2 had a trigger operated switch for the ionizer, but that was replaced with just a simple toggle. permalink

I’m amazed at how many people are willing to chop up their brand new toys. Take [edahc]’s brand new MacBook Pro. He decided to mount a Sony Puppy FIU-600 fingerprint scanner in the case. The device is powered directly from the DC board. I think the MacBook Pro may actually lend itself more to these types of modifications than most laptops because of the large flat metal surfaces on the case. More so than say your standard lumpy plastic Dell. permalink

Eddie has an interesting writeup about his experience playing around with echo location . He uses a cheap computer speaker and microphone for all of the measurements. The program he wrote generates a sweeping chirp from 5-20kHz in the space of 4.5 milliseconds. Eddie knows what a perfect echo would look like so he can compare the measured values to the theoretical to determine the distance. For his final test he moved the box while it took 150 measurements. This data generated a parabola showing where the object was in the room. Have a look at his site for more details and his code if you are interested. permalink

Using Radiosondes As Cheap GPS Trackers
Eliot
[ "gps hacks" ]
[]
A Radiosonde is an inexpensive sensor package that’s intended to be used with a weather balloon for atmospheric measurements. The device transmits data in the 403 MHz band after being launched and they usually aren’t recovered after use. You can pick them up for very little money on eBay so [Nick] thought they might work well as a low cost GPS tracker . Unfortunately the Radiosonde doesn’t transmit standard NMEA GPS data, but GPS doppler measurements. It’s hard to determine what those are actually useful for. Nick did find one other paper documenting an unsuccessful attempt which he has posted to his site. So now Nick is looking for some help either making the data more useful or coming up with a functional device that’s just as inexpensive. Anyone got any leads? permalink

Fun FON Hacking
Eliot
[ "Wireless Hacks" ]
[]
With FON now selling their “social routers” for $5 a piece it seems like a good time to mention Hack-A-Day reader [Steve Anderson]’s previous FON hacking experience. By purchasing one of FON’s subsidized routers you agree to participate in their network for at least one year. Steve had a look at the patched OpenWRT firmware FON uses and found the heartbeat system they use to monitor compliance. He then swapped out the firmware and spoofed the heartbeat with a cron job. This hack is an ethical trade off: remove FON’s firmware and violate their terms of service or keep FON’s firmware which probably violates your ISP’s TOS. In related WRT54G news: you can now flash Linux onto v5 and v6 routers without hardware modification. So if you’re at all worried, just buy one for the regular price off the shelf.

It isn’t your standard line follower, but if you draw a path using two strips of tape the Roomba will gladly stay inside. Here’s a CoralCDN link to the video . permalink

[xander] sent in links to two machines designed to solve padlocks automatically. The first one just modified an old robot project since it already had the necessary stepper motor. The second one was built from scratch and includes a solenoid to test the lock. Both systems are just brute forcing the combination, but they do use some shortcuts. Even though locks have 60 numbers there is less than 20 actual divisions. Also, multiple final numbers can be tested without putting in the first two. With these two shortcuts there are approx. 400 passes. These machines can solve a lock in about 30 minutes. Of course we’ve shown before that any human can solve one in about 10 minutes . permalink

How-to Build Your Own CNC Mill

[ "cnc hacks", "Misc Hacks" ]

Yes folks it’s true: You can build a computer controlled 3-axis circuit board mill from cutting boards, a pile of printer parts and a Dremel. My coworker [Will] has posted the third and final installment of his CNC machine build on Engadget. This project was launched when Will stumbled across plans for an incredibly elegant and cheap ($22~$30) 3-axis stepper motor controller that originally appeared in Nuts&Volts in 1994. It uses a discontinued UCN5804B chip, but he lists a source for them. Building the controller and scavenging stepper motors from old dot-matrix printers is covered in part 1 . For the body of the machine Will chopped up a couple cheap 1/2″ thick cutting boards from Sam’s Club. The polyethlene probably isn’t as good as say Delrin but it wins out for availability. Steel rod from the hardware store is used for the linear slides. Part 2 covers the constructions of the first axis (the table) which rides on inch long nuts on threaded rod. Part 3 covers assembling the final two axes in the head and installing the Dremel’s flex head. Amazingly he nearly got the entire thing built in the span of two evenings.

Want your home automation system to know the exact position of your garage door not just whether it is open or closed? Then the ultimate garage door monitor is for you. There has got to be at least one person that needs that, right? Well for the rest of you it is a handy guide for how-to implement analog sensors (like this potentiometer) into your home automation by way of an analog to digital converter.

Safe Autodialer

Two clever students at MIT have built this impressive brute force safe cracker . Their target: a document safe with a S&G 8400 lock. The 8400 is a group 1 manipulation proof lock. Group 1 locks will resist manipulation by an expert for at least 20 hours. These guys used a stepper motor to move the dial and built a custom controller for it. The dial has butterfly knob in the center which must be rotated before and after each combination. That job is handled by a hobby servo. The torque required to open the safe is higher than the stepper motor, so when the optical encoder detects that the motor has stalled you know you’ve found the combination.

IR Triggered Projection Clock

Inspired by raphnet’s projection clock , imakeprojects decided to build their own version . The clock only turns on when a source of IR light is pointed directly at it (i.e. television remote). This would be good for a room that you would normally like as dark as possible, like a home theater. The clock uses a 38kHz IR detector to trigger a Luxeon LED. You need to rotate the polarizing filter on the clock so that an inverse image will show up on the wall. imakeprojects was able to get a clear image without a lens while projecting up to 6 feet.

Alpha Radiation Visualizer

[ "digital cameras hacks" ]
[]
[Jared Bouck] certainly has a unique project on his hands this time. He started out wanting to build a somewhat complex system for visualizing Cherenkov radiation . With a little investigation he found some new ideas and decided to build a really compact apparatus . Cherenkov radiation is seen as a blue flash when a particle passes through a medium at a speed greater than the speed of light in the medium. Jared used a webcam CCD as the medium and a small piece of radioactive americium sourced from a smoke detector. The camera housing is sealed from any light leaks and is shielded to block EMI. Watching the camera output you can see flashes of white and blue streaks.  It’s a neat home built demo and I bet it could be used as a random number generator as well. In the real world, scientists use Cherenkov radiation detection to determine fission reaction intensity, measure radioactivity in spent fuel rods, and detect the origin of cosmic rays. Similar techniques are used in neutrino detectors like the massive IceCube project. permalink

[ Igor Carron ] pointed out that Derrick Parkhurst and his colleagues at Iowa State have been hard at work improving their lightweight eye tracker that we covered in January . The new version uses digital cameras instead of analog ones. This time they’ve included step by step build instructions instead of just a PDF describing the device. Most of the build involves removing the CCD from a couple cheap webcams and then building an extension back to the board. All of this work is part of the Human and Computer Vision Laboratory’s open-source openEyes project.

Every couple months I get a tip about how to get unlimited calling for minimal money.

First you need a cellphone plan that has free inbound/outbound calling to your home number. You use a home number from a VOIP provider that lets you forward inbound calls to your cellphone.

Minty Boost, AA Based USB Charger

[ "Misc Hacks" ]
[]
Limor a.k.a. Ladyada has been a long standing staple in the Hack-A-Day community and we were more than happy to hear about her latest project. The Minty Boost is an improvement on the idea of building a battery powered USB charger. Most designs (including ours) use a 7805 linear regulator with a 9V battery. Even in the best case the regulator is only about 60% efficient which means you’re losing at least 1/3 of the power to heat. Limor’s design is a much more efficient boost converter design and uses far more common (and rechargeable) AA batteries. She’s got a thorough write up on how to build the converter in an Altoids gum tin. The end result is 82% efficient and can effectively double the play time of a video iPod. The guide doesn’t end there. Limor actually wrote this as a demonstration on what goes into a making a kittable project. She covers the entire process from component selection, to mass PCB production, to what her final cost break down is. The guide is full of pictures thanks to some good planning as well. Of course the most interesting thing we learned from the guide is this: despite using the tins all the time, Limor finds the taste of Altoids gum disgusting. [The guide is on her site, but we’re linking to the version on Instructables since we’ve managed to DDOS her site in the past… by announcing that her site was back online .] permalink

Once the cable is complete you can use it get a serial console, add GPS or dump debug info along with many other possibilities. A remote emulator program is provided. permalink

Computer Remote Using Xbox Receiver

[Odin84gk] always wanted a remote control for his PC. He didn’t want to spend a lot of money to get a good one or waste money on a cheapy. He decided to go with something he already had: an Xbox DVD kit . He built an adapter cable for the Xbox receiver using instructions on redcl0ud’s site . Using the standard setup the remote driver just spits out key combos, but to make the remote truly flexible he combined it with AutoHotKey . AutoHotKey catches the key sequences and can execute complex scripts based on them. permalink

The S1MP3 is a Chinese MP3 player branded by at least 50 different manufacturers. Some only play music, but others can play MP4. Have a look at the gallery to get an idea of the variety. S1MP3.org has been developed to support users of the players and create opensource firmware. Here’s their guide for upgrading the memory of a player. If you can’t get a donor player, the site says you can get a new 1GB memory chip for $9. [thanks ex-parrot ] permalink

[Jeroen Domburg], one of our favorite hackers, has posted how to replace a cold cathode based backlight with white LEDs . He had recently purchased an HP Jornada 680 on eBay and the backlight was looking very pinkish. The Jornada has a QWERTY keyboard, CF slot, PCMCIA slot and can run Linux . Sounds like a pretty decent mini-terminal (now that we posted it you won’t be able to find one cheap though). In the space where the backlight was he was able to place 14 white LEDs. To get the  40V necessary to drive the series he built a boost-converter using an ATTiny13. The new backlight is just as bright and uses a 1/3 less power than the original. Half the Jornada’s power was being used by the original backlight, so this mod should give a decent increase in battery life as well. permalink

[th0mas] has a fun guide to modifying the boot image in your BIOS . This could very easily brick your laptop, but it’s interesting to see how it’s done. He starts by dumping the plain text strings. The magic number for bitmap format appears in the file so he copies a large chunk of data starting at that point. th0mas opens this in MSPaint to maintain the format. After modifying the image it’s placed back in the BIOS file and a couple checks are performed to make sure only the image data has changed. The final section involves running the flash utility in a debugger to find where it checks the CRC. By modifying the program he can then flash the image without the program complaining. permalink

Gerald Heine’s stereo microscope uses a field sequential method for generating 3D video. A CRT draws half the screen’s lines with each frame. So, if you send the video from two different cameras on alternating frames you can generate a 3D using shutter glasses. Gerald’s setup uses the sync signal from one camera to control the other. Both video signals are fed into his custom 3D video sync box which combines the frames into a single video feed and also outputs a control signal for shutter glasses. permalink

[ "Xbox Hacks" ]

Monday brought news of backups successfully booting on Xbox 360s with modified DVD firmware images. LittleJonny put together a tutorial on how to boot two different DVD drive firmwares . To perform this mod you need a second SST 39sf020a flashrom plus some resistors. The two flash chips are soldered directly on top of each other except for pin 15. Two wires are then attached. Which flash chip is used depends on which wire you pull to ground. Just add a switch and you can install a modified firmware on the second chip while keeping your original. I’m guessing Microsoft will put firmware detection into the dashboard to combat this, but this will keep your original firmware intact so you won’t have to reflash if something breaks. permalink

Backups can now be booted on the Xbox 360 according to Xbox-scene . The firmware was released by Commodore4Eva who previously released a functional Xbox 1 firmware. It works under the same idea as the final Xbox hack: it patches the response to the media check into the DVD drive’s firmware. So the drive responds with an all-clear without even checking the DVD. This hack works on units with the Toshiba-Samsung drive. The new firmware also lets you use the drive under Windows for easy game ripping. There are some quirks to it, but it sounds like everything you need is included. It’s unfortunate that this happened before they were able to get executable code running on the machine. Now that the bootleggers have what they want I’m afraid it might take some steam out of the homebrew movement. permalink

I usually don’t post Engadget material since they get more traffic than us, but with all the E3 coverage going on I wanted to make sure Will’s iPod dock project got the attention it deserves. Will had originally planned on doing this all in one post, but there ended up being so much material we had to do it in four. The idea was to breakout all of pins in the dock connector into usable connections: everything from line-out to USB to serial. Even if you don’t have (or even like) an iPod you might find this project interesting because it’s really a tutorial on board design in disguise. Part 1 covers how to create a new component in EAGLE. Part 2 has how to create the schematic. Part 3 shows how to generate and tweak the board layout. Finally in Part 4 he goes through the process of actually etching the boards. What’s next? Well a decent case would be nice; which seems like perfectly good excuse for Will to build vacuum table. Look for that in the future. permalink

Helium Balloon Aerial Photography

[ "digital cameras hacks" ]

So, you’ve got an itching desire to inflate 150 helium balloons, but have no idea what to do with them afterwards? Well, readers Stefan and Michel decided to build a simple aluminum frame to mount a cheap digital camera and do some aerial photography . Instead of building a complex timing system they just attached a strong motor from a security camera. It’s powered by a AA and is geared really low so it only triggers the shutter every 12 seconds. They deployed the rig from the fortifications surrounding Wilemstad in the Netherlands. There are several pictures of the city (and the occasional envious child) on their site . If you follow the “ continue reading ” link you’ll see a couple more pictures of the camera mount. permalink

Old Pen Plotter Converted To Vinyl Cutter
Eliot
[ "Peripherals Hacks" ]
[]
Vinyl cutters can be very expensive, so [vinyl hacker] decided to share with us the alternate route some people have taken. Here is what you need to get started: An old HP pen plotter with a serial connection. A compatible serial cable . A blade holder (Roland blade holders don’t fit). Some Roland vinyl blades. Cutting software like SignGo of DAHEDIsign . Vinyl (found in sign shop dumpsters). The main resource for these plotter/cutters seems to be luberth.com . It’s hard to navigate, but all of the info you need should be there. Now you can cut stickers, stencils, small signs for very little money. permalink

C.K. has always been the goto guy around here when it comes to testing out new PSP hacks. Firstly because he was writing a PSP Hacks book and had plenty of hardware laying around; Secondly because it kept me from having to field questions in the excessively long firmware threads. The book has been published and O’Reilly has posted some sample chapters. Thomas Novotny wrote this chapter on interfacing the PSP with peripherals over IR (PDF).

There is a set of bike pedals attached to each seat. The chain on each one drives a sprocket attached to the chair’s pivot point. Spinning the pedals tilts the chair and the entire frame reacts by rotating. They only had one set of pedals attached, but it was more than enough to spin the wheel at a pretty good clip. It did look like some damping on the chair pivots would help, since the chairs would swing pretty wildly. I’m sure adding two more chairs would help as well. A Cyclecide creation [thanks Sasha ]

We saw Amal Graafstra, the author of RFID Toys, at Maker Faire.

After he cracked open the iTrip, Josh compared it to an earlier hack we featured and noticed that the wiring was backwards which explains why the acc. port devices won’t work on different generations.

I found this self-balancing unicycle via Trevor Blackwell’s site . Dr. Hofer’s self-balancing unicycle uses a wide tire for lateral stability. Trevor had spent several months learning how to ride a unicycle before building his; the large tire makes the learning curve for this one a lot less severe. The project site is in German , but I found one write-up in English . The majority of it is dedicated to the control scheme. It is very difficult to model the unicycle as an inverse pendulum due to so many unknowns. Dr. Hofer’s team used fuzzy control instead which let them apply several layers of rules without requiring a lot of previous knowledge. Here’s a photo gallery of the device.

As a follow-up to yesterday’s post, [owen] sent along a link to his computer controlled router table for balsa cutting . This was his project before switching to lasers and sheetmetal . The write up starts with an interesting discussion about CNC not really being a magical tool or time saver. Sure, it can be pretty quick about cutting accurate pieces, but you still have to assemble it. Most likely all of the time you saved cutting was spent designing and prepping, which you could have spent cutting accurate parts by hand. Owen had extra time to spend designing since he was traveling for business. He does admit that the ability to quickly generate replacement parts has made him a more courageous pilot. Other gems from yesterday’s comments: CNCZone is apparently the one-stop shop for all of you CNC hobbyist needs. [javamoose] pointed out that he’s nearly done with his scratch built CNC machine seen on bit-tech.

The Team Hack-A-Day forum recently started a thread to discuss homebrew CNC . Computer Numerical Control machining is a very popular topic in our community because of the prohibitive cost of buying a machine off-the-shelf. Searching through the archive it seems we’ve only covered one actual CNC machine ; since people have been building these things for so long, it’s hard to come up with the definitive CNC project. We’ve also featured the Etch CNC , designed by the AXIS developers to verify their software. My coworker Will O’Brien, who writes how-tos for Engadget , recently started working on a new CNC mill . You can expect a write-up on that in the future. Also, Lady Ada recommends Drill Bit City for sourcing cheap carbide bits. If there is enough interest, Team Hack-A-Day might add another forum for CNC projects. For those who don’t know: Team Hack-A-Day was founded by Hack-A-Day readers to support our Folding@HOME efforts. Through their work we are now the #37 team (and still gaining) having produced nearly 20 million points in the last 8 months. [thanks Tired2, op for #hackaday on EFnet] permalink

Holga Style Digital Camera Lens

The Holga is a cheap medium format film camera that has achieved cult status for its inconsistent, truly unique photographs featuring blur, light leaks, vignetting, and distortion. Poor quality digital photos aren’t nearly as interesting and [Joachim Guanzon] wanted to achieve the Holga effect without using robotic Photoshop filters. He constructed this lens for his Canon 20D . The base is an EOS body cap with the center drilled out. A tube is constructed from a white film canister and the Holga lens is mounted inside. The tube length increases the usable distance of the camera and the white body lets some light leak in. A lens cap with a 3/16th inch hole is snapped over the top. The hole creates a vignette and since it isn’t permanently attached the pattern will be more random. Check out Joachim’s sample photos . permalink

Make Your Own Liquid Magnets

Here is a nice followup to yesterday’s video: How to make your own ferrofluid . This guide comes from Dr. Anne Marie Helmenstine at About.com The fine folks at Sci-spot seem to have the original with pictures. The composition of ferrofluid by volume is about 5% magnetic solids, 10% surfactant, and 85% carrier. The surfactant is what keeps the particles from sticking together permanently. Ferrofluids are often used for damping speakers and in disk drives. This procedure doesn’t seem to complex and one of the main components is ferric chloride, a.k.a. PCB etchant. Thanks go to [ Jason Uher ] who sent in this tip and says that it has worked out quite well for him in the past. [ photo credit ] permalink

Bawls Automatic Light

[Alan] from Hacked Gadgets put this Bawls automatic light together pretty quickly. He used a photocell, transistor, LED, and a 9V battery to make it turn on automatically when the lights go out. It creates a nice eerie blue glow. You might remember that he isn’t the first Hack-A-Day reader to get lured in by the Bawls lamp. [Chris] made a cold cathode Bawls lamp last fall. I found this picture on ZapWizard’s photostream as well. permalink
