If you’ve got a Samsung Vibrant and want to take advantage of that unlimted 3G account you can tether without rooting the phone. This method uses a USB cable to provide internet access to Windows XP and Windows 7 computers. Samsung’s own Kies software handles the tethering, as long as you have the magic number to get connected on T-Mobile USA networks; ‘epc.tmobile.com’ for the APN name and ‘*99#’ as the phone number. [Zedomax] made the video after the break which takes you through the tethering ritual.

Wired took a look at this year’s Ninja Party badges. We were giddy about all the goodies involved in last year’s must-have badge that served as an invitation to the party. It was tailor-made for hacking, including an on-board disassembler. This year’s details are still a bit sparse but the offering is more along the lines of a market-ready product. The badges come in hand held gaming format, with a d-pad and two buttons. They can connect wirelessly with each other and with hidden base stations, allowing participants to fight in the digital realm for LED-indicated achievements. The teaser is tantalizing and we can’t wait to hear details about the real/digital gaming adventure soon to unfold.

If you’ve got an iPhone or Android device that you use with a Wii remote when gaming, this quick hack will give you the third hand you need to manage all of that hardware. [Syanni85] mounted his Android phone to a Wii wheel for just a few dollars in parts. He ran across the wheel itself at the dollar store, and the phone is held in place using a universal mounting bracket. A small square pad sticks onto the back of any device and mates with a base. He cut off the unnecessary parts of the base and glued it to the back of the wheel.

If you haven’t tried using a Wii remote with your phone yet, find out how to do it with iPhone or with Android.

[Michael Vincent] turned his TI-84 Plus into a spectrum analyzer. By running some assembly code on the device the link port can be used as an I2C bus (something we’ll have to keep in mind). After being inspired by the cell phone spectrum analyzer he set out to build a module compatible with the calculator by using an I2C port expander to interface with a radio receiver module. Now he can sniff out signals between 2.400 and 2.495 GHz and display the finds like in the image above.

[Thanks Cecil]

Our favorite Soviet-Era display that found its way into a present-day kit now displays time from orbiting satellites. A GPS module patched into an Ice Tube Clock with modified firmware will be able to provide a satellite-synced time. The firmware, modified by yours truly, parses the GPS module’s NMEA RMC sentences for the time and date information and then updates the clock’s time and date. Fun was had making sure the alarm went off at the correct times when the time was updated by the GPS. Overall, it was a fun project and we look forward to seeing additional Ice Tube Clock hacks.

[Petar and Sylvain] are teaching this robot to flip pancakes. It starts with some kinesthetic learning; a human operator moves the robot arm to flip a pancake while the robot records the motion. Next, motion tracking is used so that the robot can improve during its learning process. It eventually gets the hang of it, as you can see after the break, but we wonder how this will work with real batter. This is a simulated pancake so the weight and amount at of force necessary to unstick it from the pan is always the same. Still, we loved the robotic pizza maker and if they get this to work it’ll earn a special place in our hearts.

The Sprint version of the Palm Pixi doesn’t have a WiFi option but the Verizon version (called the Palm Pixi Plus) does. The hardware is almost the same and [Gitit20] figured out how to do some hardware swapping to add WiFi. The radio board inside the phone is fairly easy to remove. Close inspection of the Sprint radio board shows some solder pads where a WiFi chip would go. The Verizon version has this chip, and moving that radio board into the Sprint phone will enable WiFi. This is strictly a hardware hack as the device identification (IMEA) is paired with the motherboard and not the radio board.

Now we want to see someone source that WiFi chip, solder onto the board, and enable it within the OS so that we don’t need a donor phone to make this work.

[Thanks Juan]

[Retromaster's] Ultimate Floppy Emulator is a wicked display of hardware mastery. It is the culmination of several design stages aimed at replacing an Amiga floppy drive with a modern storage solution. You may be thinking that using an SD card in place of a floppy isn’t all that interesting but this hack does much more. The board, controlled by a PIC32, patches into the Amiga keyboard and monitor. This allows you to bring up an overlay menu for controlling the emulator in order to configure which virtual floppy disk is currently ‘in the drive’. He’s even gone so far as to add a piezo speaker to mimic the sounds the original drive head would make while reading a disk.

[Thanks Gokhan]

[Derek Hughes] wanted to use inductive charging on his cellphone without voiding the warranty. He picked up a Pixi charging backplate meant for a Palm Pre and scavenged the coil and regulator circuitry from it. To make the electrical connection with his HTC HD2 he removed the mini-USB plug from a charging cable and connected it with 30 gauge wire. The whole package will fit beneath the back plate for use with a Touchstone charger (as we’ve seen with the HTC Evo) but there was one problem. The metal backplate from the HD2 interferes with the inductive charging. For now he’s using tape to hold everything together while searching for a plastic case replacement.

He walks you through the hack in the video after the break. We’re usually not worried about voiding warranties, but a phone like this takes a lot of abuse and having warranty protection or even a service agreement isn’t a bad idea.

For those living under a rock, the latest ‘greatest’ news to hit hacking front page is the the Copyright Office granting Six Exemptions Regarding the Circumvention of Access-Control Technologies. Of the six the one of the two regarding iPhones is as follows,

“(2) Computer programs that enable wireless telephone handsets to execute software applications, where circumvention is accomplished for the sole purpose of enabling interoperability of such applications, when they have been lawfully obtained, with computer programs on the telephone handset.”

Which (along with section 3) really just means that you can unlock and crack cellphones and companies can no longer fine you $2,500. Not that many ever have but the threat was there. Apple however, can and still will void your warranty if you jailbreak.

The 4 other areas not involving phones are the ability to circumvent DVDs for portions of video, video games in order to better the security of said game, computer programs that require dongles but dongles are no longer available, and literary works that prevent read-aloud or rendering to a specialized format.

One tidbit I keep hearing about in these exemptions is the ability to now break DRM on music, as much as I wish this were true, I can’t seem to find any sources on it, sorry pirates.

Regardless, now that the world is one step closer to an open framework, whats changed? For me, I’ve been jailbroken for years so sadly nothing. If you agree with the ruling, disagree, or just want to tell about your now legal jailbreaking joys, please leave a comment.

Some new products have worked their way into our hands and are just waiting for some awesome Hack a Day logos to be put on them. We’ve added a couple bags, some huge mouse pads as well as normal ones, and we’re considering adding the Hack A Day badge. You’ve seen the badges before, when we took them to CES. [Devlin] estimates that the cost would be $25 each before shipping. We would like to get some feedback before he starts pumping these things out. How many of you want one?

If there is one thing we like, it’s a fellow hacker so enthusiastic about his or her work that they write the article practically for us by including as much detail and information as possible.

In this two part hack, [Scott] wrote in to let us know not only about a high school built high altitude balloon, but also his $5 long range RF transmitter. The former is simply GPS and video data logged over the flight, but [Scott's] specialty comes in the latter. A 74HC240 octal buffer is using to amplify the signal (Morse code) from an ATTiny44a with a 29MHz oscillator, producing a usable signal as far away as 200 miles.

It is low bandwidth, but if you’re looking for a simple transmitter in your project and need something with more power (and a smaller package), this might be the ticket.

[Aleksander Zawada] makes vacuum tubes in his home. One of the most challenging builds he has taken on is to produce a working Nixie tube. He describes the process in a PDF, covering his success and failure. It seems the hardest part is to get the tube filled with the proper gas, at the proper pressure, and firmly seal it. In the end he managed to make a tube with three digits (0, 1, and 2) that worked for about 700 hours before burning out.

[Aleksander] joins [Jeri Ellsworth] on the short list of hackers who can pull off extreme industrial manufacturing at home. Kudos.

[Thanks Duncan]

In an effort to improve his marital standing [Tech B] hacked an air freshener to make it Internet controllable. The main component here is a Glade Sense and Spray. It cost him $7 and is meant to spray out some sweet smells when it senses motion in the room. The unit also has a manual spray button which he patched into with the help of a relay. From there some Arduino code and an IRC bot take over, letting him unleash freshness from anywhere he has IRC access.

When reading about this we were also thinking: “motion sensing circuitry available at local stores for just $7?”. We may have to conduct an investigation into the alternative usefulness of that package.

If you have another brand of automatic freshener around it should be just as easy to hack as this one was.

[Matthew Arnoff] built an 8-bit computer around the Motorola 6809 processor. He chose this processor because it seems there are a lot of Z80 builds out there and he wanted to try something different.

This actually packs quite a punch. He’s clocking the machine at 2 MHz with 512 KB of SRAM memory. Compact Flash that is FAT formatted provides mass storage. He’s using a serial connection for a user interface. After the break you can see his oscilloscope is used as the monitor. This was easy to accomplish by connecting the serial out to Terminalscope, one of his previous projects.

[Thanks Marc]

[Magx1] has filled his living room with laser-y goodness. You can get tons of build pictures and information from his Flickr set. There are many cool aspects of this build, but one that stands out is how he gets his C02. He simply exhales into a balloon. Check out the video after the break to see him melting glass with his laser.

[Norm Santos] whipped up an LED light board that you can draw on through their web interface. We tried it out but unfortunately the live feed is currently offline. That doesn’t diminish our appreciation for the time-lapse build video after the break. Indeed it was a mountain of hot glueing and a couple of days of soldering. Our only beef is that for every LED on the board there are three empty peg holes. To us this is just begging to be augmented with blue, green, and white LEDs for a more spectacular result. What they have now encompases 350 LEDs managed by five microcontrollers, which took about two days to solder (for five people) and to hammer out some code.

[MC] realized he had forgotten about an order for 2000 cut wires that was now due in a few days. Rather than dropping everything to complete the task, he whipped up this machine to cut the wires for him. A PIC 16F628 board drives a couple of battery-powered drill motors. One of them powers two lawnmower wheels for the feed, and the other turns a pin that squeezes the wire cutters. It’s not as advanced as the cutter/stripper from last year, but it gets the job done.

After the break you can see it does what is intended. The final product took about $80 and 12 hours of his time to build.  [MC's] planned improvements include more accurate wire measurement, plus an LCD and button based user interface.

The HOPE conference was last weekend and [Nathan] spent some time with fellow members of Makers Local 256 developing this badge proximity sensor. They took one of the HOPE badges, which have a radio on board for the tracking network, and wrote code for its MSP430 to detect other badges nearby. It uses a Geiger counter they brought with them as an enclosure, re-purposing the analog gauge to reflect the level of active radio signals in the area. You’ll find their demo clip embedded after the break.

If you managed to get your hands on one of these badges, don’t be shy about sharing your hacks. We want to see them.

Adafruit’s got a handy breakout board for the DS1307 RTC available. This chip isn’t nearly as accurate as the DS3231 used in the Chronodot but it’s quite a bit cheaper. The breakout makes this easy to breadboard or plug into an Arduino and has everything you need; clock crystal, a backup battery, filtering capacitor, and pull-up resistors. Our favorite part is that Adafruit designs are open source so you can etch the board yourself if you checkout the files from their git repository. This will make a great addition to our prototyping hardware collection.

Incidentally, we were surprised to see the choice of 2.2k resistors for the I2C bus pull-ups. We were under the impression that 4.7k was a standard value here. We’d love to hear your thoughts on this in the comments.
