[Jonathan] sent us a pretty in-depth writeup of his car computer system.  This isn’t your typical quasi navigation/media system as you would usually expect with this title. What he has done is made a remotely accessible monitoring computer that can tell him everything from engine data to physical location of the car on a google map.  He can start, stop, lock, and unlock the car as well, as long as the car is within a 3g network. This is pretty impressive and we see tons of uses for this, from analyzing your own data to keeping an eye on those pesky teenagers when they borrow the car.

Bendërbrau Now A Reality

December 10, 2009 by 23 Comments

It appears to be 5 o’clock somewhere as everyone seems to have only one thing on their mind. [Simon] set out to make his own Bender Brewer from the television show Futurama. But he made sure to include some key functions from episodes in the series. First and most notable Bender’s stomach contains a beer brewing kit, we think a coffee roaster would have been better, but to each their own.What we hackers love best is the ‘brains‘ of Bender, a 6502 processor controlled via remote to play a selection of 15 random sayings, including the infamous “Bite my shiny metal”, well, you know.

Finally, yes, we do realize this project was started and finished about 2 years ago. We like to think we allowed it time to ferment.

Virtual Theremin

[Mojo] has taken a lot of the complex circuitry out of the mix by creating a virtual Theremin. A Theremin is an electronic instrument, usually with two antennas, that senses the proximity of the player’s hands to the instrument and responds accordingly.

This design, called the AirDeck, uses a Wii remote as an IR sensor and two gloves with IR LEDs in them. Data from the Wii remote is processed by a custom Java app that converts it into sound. [Mojo’s] interface also includes some alternative options such as a turn-table scratch interface.

In the end this is still just a synthesizer/midi controller and cannot stand up to the real thing. However if you’re not an accomplished player you’ll probably never notice the difference.

Remote Uses No Batteries

November 20, 2009 by 32 Comments

How often do you change the batteries in your television remote control?  Yeah, basically never. But that’s a tribute to how efficient the device is and not a reason to overlook this development. NEC is showing off a remote control that uses no batteries. Power is generated using the piezo effect that occurs when a button is pushed. That is to say, when a crystal is compressed it emits a tiny bit of electricity which is harnessed and used to power this device. This is the same principle that is used in the electricity producing sidewalks tested in Japan.

It’s pretty phenomenal that they can run the device using this method. Right now there’s only a handful of buttons but we’re sure there’ll be advances in the technology. There’s a ton of use for this if it can be miniaturized. It is using radio frequency instead of infrared, making it a useful development in wireless doorbells, garage door openers, key-less entry fobs for your car, and many more applications.

Apple Remote Arduino Shield

[Computergeek] made an Arduino Shield in order to use it as an Apple remote. We like the construction technique that he used; taking perf-board and soldering the circuit and using stripped wire to interface with the pin sockets on the Arduino. He’s written the code needed to function as an Apple Remote but this shield has a lot more potential. This is an excellent opportunity to delve into the different IR protocols out there and create a universal remote for all of your random devices. We’d also want to give it a try as a TV-B-Gone.

The parts are easy to find or salvage without putting in an order.  We’re not certain about his design, he should probably have invited a resistor to the party the two IR LEDs are having.

TV-B-Gone-zilla! Rawr!

tv-zilla

TV-B-Gone: antisocial nuisance or harmless prank? Whatever your feelings, there’s no denying this device has become a staple of the DIY hacking crowd, as evidenced by the countless derivatives since hatched. This latest mutation crushes them all.

[manekinen] from the Polish electronics blog Elektroda (“Electrode”) wasn’t satisfied with high-power TV-B-Gone designs using multiple 5mm infrared LEDs, so he created his own using a single one-Watt monster. The device is concealed in an ordinary flashlight casing, making it somewhat inconspicuous. A custom PCB containing an ultra-minimalist version of the TV-B-Gone circuitry sits just behind the reflector. The choice of reflectors determined maximum distance vs. coverage…they opted for distance. Specific figures aren’t given, but we estimate this thing could shut off televisions on Mars.

The original article (Polish or Google-ized English) includes construction photos and an archive (.rar) of project files including Eagle schematics and C source code.

Would it be totally irresponsible to mention there’s now a 3-Watt version of this LED? We’re just sayin’.

Garage Door… Packet Sniffer

October 3, 2009 by 46 Comments

Some type of logger or sniffer exists for almost every form of electronic communication. Your keystrokes, phone conversations, and wireless networks could all be monitored. In this awesome proof-of-concept project, [James] expanded that array to include garage door openers. After receiving a piece of chain mail which stated that criminals have the technology to record any remote code and play it back, [James] wondered if he could build such a device that would work on at least his opener model.
