A few days ago, we mentioned the new ARM-powered Teensy 3.0 project on Kickstarter. The creator, [Paul Stoffregen], decided to share the trials of building a test fixture along with a shocking comparison of the accuracy of different PCB manufacturers in an update to his Kickstarter. Because [Paul]‘s Teensy 3.0 has more IO pins than should [...]

[Paul] spent his summer bringing an iMac G3 into this decade. There’s plenty of room to work with since he removed the CRT which originally occupied most of the computer’s space. The final project is much more powerful and since he preserved most of the metal mounting parts inside it remains quite strong. He started [...]

Chaos Communication Congress 23th (23C3) 2006 Abstract: To encrypt all your mobile phones to protect it from overzealous eavesdroppers, you are currently limited to using special hardware such as the Cryptophone. The disadvantage of cryptophone is that it only works with other cryptophones. To work around this, we turn mobile phones from "voice" phones into VOIP phones. Using the SIP protocol for VOIP and IPsec/L2TP or Openvpn as our VPN, Leigh Honeywell and Paul Wouters connect their mobile phones fully encrypted to an Asterisk PBX server. The presentation, given by Asterisk expert Leigh Honeywell and VPN expert Paul Wouters will start with a description of the demise of the "old" telecom sector and the end of "voice" conversations. The replacement, Voice Over IP promises a lot of good things, but it comes at a price. Hacking VOIP calls on the internet is much easier. We can no longer trust the security of the telecom infrastructure. Forged caller-ID, charging someone else for your calls, breaking through firewalled networks, or abuse via VOIP services like Google, Jajah, Skype or others. We will demonstrate some of these attacks. To address these problems, we need to be able to both authenticate and encrypt our calls. The solution presented is build with using Freely available (mostly open source) software and we will explain various aspects and ideas behind our setup and why we choose the various protocols and software packages. We are currently working with various phones, such as the Linux based GreenPhone, the XDA's and other phones running either Linux or Microsoft Windows PDA phones. Leigh and Paul will also hold a workshop, where they can go into the deep technical details on how to build your phones and your servers, and where people can try out our phones and secure PBX.

[Paul] is sick and tired of his homemade root beer being flat. He analyzed the problem with his carbonation techniques and ended up with a method of force carbonating beverages using dry ice. He starts of by discussing the various methods that are used to carbonate beverages. There’s the old yeast and sugar trick that takes place [...]

[Paul] is at it again with some kinect controlled fire poofers. You may remember [Paul's] previous shenanigans with the gigantic hand made hydraulic flame-sailed pirate ship. This time he is building a small flame poofer (possibly a series of poofers) for SOAK, a regional (unaffiliated) Burning Man style festival in Oregon. Any one who remembers [...]

As far as battery technology goes, Lithium Polymer cells are the bee’s knees. They’re powerful enough to handle very demanding applications and come in a multitude of sizes for any conceivable application. There’s a problem with LiPos, though – they have the tendency to explode when charged incorrectly. Luckily, [Paul] sent in a great tutorial on [...]

[Paul] was looking to spice up his holiday decorations this year, so he picked up some GE Color Effects lights and started hacking away. We’ve already seen how hacker-friendly these LED bulbs are, which is why [Paul] decided to give them a try. His ultimate goal was to synchronize several sets of lights from one [...]

[Paul] a.k.a. [VoidFraction] put up the source and documentation for his sculptures made with laser cut polygons. For computing his triangles, [Paul] developed LcAgl, an algorithm that transforms a 3D model into the AutoCAD file needed to cut a whole bunch of triangles and connectors. This file was shot over to a laser cutter and [...]

Relief is here from long compile times when developing firmware for your Arduino project. [Paul] was puzzled by the fact that every file used in a sketch is fully recompiled every time you hit upload–even if that file didn’t change. To make things more confusing, this behavior isn’t consistent across all Arduino compatible hardware. The [...]

All EL wire drivers use a resonator circuit to supply power to the EL wire. It’s an efficient system, but [Paul] noticed that there was some color change when powering different lengths of wire off of the same driver. He realized that this is because of the changing frequency of the resonator circuit, so the [...]

[Paul] has been working on porting over Arduino libraries for use with the Teensy microcontroller platform. This tends to be pretty simple since they both use the same Atmel chip architecture. But once in a while he finds the Arduino libraries are not what they’re cracked up to be. When looking to port over a [...]

We feel like trumpets should be sounding. Someone took the overused project of connecting RGB LEDs to a microcontroller and produced something useful. [Paul] created Dr. Boardman’s Color Conundrum which works much like a simple mechanical coin-op game you might find at a carnival. When switched on, a random color is displayed by the ping-pong [...]
