The Serpent Mother

serp-mother

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.

E-bike across Canada for $10

Justin Lemire-Elmore E-bike

[Justin Lemire-Elmore] spent one month riding his electric bike across Canada last summer. He made the journey from Vancouver to Halifax in 30 days using a mere $10 worth of electricity to recharge his bike. He put together a rather bizarre looking semi-recumbent bicycle to hold all of his gear. The motor controller, charge controller, battery packs, and lighting system were all his own design. He has a captivating 2 hour presentation embedded below in which he describes all the problems he had with his equipment during the trip as well as all the great experiences the journey offered.

Etch aluminum control panels

aluminum etched control panel

This clever Instructable demonstrates how to etch beautiful aluminum control panels for electronics projects. We like how similar this process is to DIY circuit board etching. Both abide by the same technique and use blue transfer paper. The primary difference is in the use of muriatic acid and hydrogen peroxide for etching aluminum.
