The Serpent Mother is certainly an appropriate name for this 168foot long snake fire art installation filled with enough goodies to impress anyone who is into flame effects. [The Flaming Lotus Girls] were allocated $60,000 in May of 2006 to bring this art project to Burning Man. A team of nearly 100 people worked together at a furious pace to pull it off. The collaboration of skill-sets is unfathomable between the metal art, firmware, software, LEDs, and propane design. The primary flames consist of 41 “poofers” along the spine of the serpent each one capable of delivering a 8′ tall flame. Tucked away near the tail is a egg that makes use of methanol and boric acid to create a massive green fireball. When the egg is open nobody is allowed with 150′ of the project. The brain that runs the beast is nothing more than a RS-485 network of humble ATmega8s. The microcontrollers are wired with XLR cable and chatting at a 19200 baud. Max/MSP is used on a laptop to control flame patterns. Here is a enjoyable write-up and video. We particularly enjoy the bit about the strange looks the team got when purchasing 50 stun guns.

25C3: Solar-powering Your Gear
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.
Tom’s RGB Mood Lamp
[Tom] has been refining a board that drives a high power RGB LED for applications like this moodlight. It’s based around an ATmega8 microcontroller. The goal was to make an RGB LED easy to work with: It can cycle between colors in standalone mode. You can control it via a serial interface. It also has a pin header to hooking up three potentiometers for manual color mixing. Boards aren’t available yet, but he’s already posted a build tutorial. The board looks straightforward enough that it shouldn’t be too hard to layout if you really want to.
Universal Joystick USB Interface
Building on his USB NES pad interface, [Raphaël] released a universal USB joystick interface. It presents a HID device with four directional buttons and eight general purpose buttons. The board uses an ATmega8 and implements USB entirely in software.
