Autoblog dug up this classic mechanical engineering project from 2006. A team of five University of Toledo students constructed a system to help parallel park a car. First, you drive nose first into the space. Hydraulic rams then lower the drive wheel out of the trunk, raising the rear of the car. The single wheel [...]

[Alex] built what he calls a light to sound converter. It reacts differently depending on the type of light: remote controls, light bulbs, TV screens, etc. A photodiode is used with an amplifier to pick up the light change. That signal is dumped through a dual opamp. He swapped in several different types of photodiodes [...]

The team from Tech-On has taken the time to teardown two interesting microprojectors. The first model they tackled was the Optoma PK101. It’s based around a digital micromirror device (DMD) like those used in DLP. Separate high intensity red, green, and blue LEDs provide the light source. A fly-eye style lens reduces variations between images. [...]

[palmertech] and [Bibin] have both completed backlight projects for the Game Boy Pocket recently. The most difficult part of the transplant is carefully removing the reflective backing on the LCD. After a thorough cleaning, a diffuser and backlight panel were added. [palmertech] used a backlight salvaged from a DS, while [Bibin] built his own using [...]

Kit builder oomlout—we’ve featured their servo bot—needed to produce a lot of precut wires. After cutting and stripping more than their fair share, they decided to apply some heavy engineering to make things easier. They constructed a machine to do the job for them. It has three main components: a servo driven wire feeder to [...]

The Formica project was our favorite presentation at 25C3. The goal is to build open source swarm robots as cheaply as possible. The team ended up building 25 robots in an assembly line fashion. With enough lead time, the price could get as low as £15 each. Each bot has two direct drive cellphone vibration [...]

Breaking from his usually routine of winning at everything, [Glacial Wanderer] has posted one of his projects that didn’t actually work. It’s a Rube Goldberg style card shuffling machine. He wanted something that was visually interesting while still randomizing the cards. A blower would be mounted to the top to mix the cards similar to [...]

While we had been excited about 25C3’s CTF competition, we couldn’t even venture a guess as to who would win. It seems the iphone-dev team weren’t satisfied to just give an amazing talk. They teamed up with the Wii hackers from HackMii to win the competition. You can see their progress during the eight hour [...]

As promised in their yellowsnow demo, [pytey], [MuscleNerd], and [planetbeing] from the iphone-dev team presented at 25C3 on their work Hacking the iPhone. The team originally formed in 2007 and this is the most comprehensive presentation on how the iPhone was compromised to date. You can find the full talk embedded above.
They opened with a [...]

[Florian] and [Xavier Carcelle] started the day at 25C3 by covering power line communication. PLC technology is not widespread in the US, but has gained popularity in countries like France where it’s included in set-top boxes. PLC lets you create a local network using the AC wires in your wall. The team started exploring PLC [...]

[Kai Kunze] from the Embedded Systems Lab at Passau came to 25C3 to talk about Cyborgs and Gargoyles: State of the Art in Wearable Computing. There have been a lot of homebrew wearable computing solutions, but [Kai] covered specifically projects that could see everyday use in the real world.
The first was a prototype system they [...]

The 25th Chaos Communication Congress is underway in Berlin. One of the first talks we dropped in on was [script]’s Solar-powering your Geek Gear. While there are quite a few portable solar products on the market, we haven’t seen much in the way of real world experience until now.
[script] selected a four segment folding solar [...]

It’s the season of gift giving. Did you get anything interesting/hackable? What will you work on next?
We gave ourselves an Android Dev Phone 1 (ADP1). We hadn’t really considered getting a G1 until the ADP1 was announced… It’s actually a lot of fun to use as our primary phone. Our favorite app so far is [...]

With another hacker conference looming in front of us, it’s time to start thinking about hardware security. Hacker conventions have the most hostile network you’ll ever encounter. [Security4all] points out that 25C3 already has an extensive page on securing your hardware. It starts from the ground up with physical security, BIOS passwords, and locking down [...]

While doing serious fruitcake research, (no, really) we stumbled across the Great Fruitcake Toss held every January in Colorado. The particular entry above caught our eye. Omega 380 was built by a group of Boeing engineers and currently holds the distance record of 1,420feet. It’s a large compressed air cannon. All pressure is human generated [...]

On a recent trip to New York City, [sherri] noticed the abundant “NYPD Security Camera” signage. She Ò on her little sousveillance tour and did some digging to learn more about the system. According to a recent NY Post article, the city intends to have 2,000 cameras installed by 2009. Each unit has at least [...]

We love old display technology, like Nixie tubes, but they’re often difficult to work with because they require higher voltages than digital logic. Vacuum florescent displays (VFD) fall into this category. While not necessarily “old”, they are becoming far less common than LCDs. The main benefit of a VFD is that it actually produces light [...]

When the RepRap team found themselves pushing the limits of the Arduino, they started looking for alternatives. They found it in the ATMega644P. It has four times the memory and four times the RAM compared to the ATMega168 used in the standard Arduino. It also has 32 I/O pins. They ported the Arduino software to [...]

[Ben Heck] has put the final touches on his Pelican case Xbox 360. This prototype was constructed for use by troops stationed overseas. When he announced the project in October, he already knew some of the hurdles he would face. An industrial Velcro style product is used for all component mounting so the air/water-tight seal [...]

As the video above shows, [Zach Hoeken] is continuing to improve on his peristaltic pump design. The moving parts in peristaltic pumps never contact the fluid being moved. Instead, they interact with the outside of the tubing that’s carrying the liquid. In [Zach]’s design, multiple skate bearings roll across the outside of the silicon tubing, [...]
