Hybrid motors are available to those without a high power rocketry certification. Look at SkyRipper Ssytems and their 29mm motors that have 2 loads for them in the G motor range.

Only requirement is that you be 16 (18 in some states) to purchase the nitrous oxide. I don't think the explosion that happened was due to a hybrid as much as it was that they were loading liquid nitrous in 99 degree F from a large (3000 pound) tank to the smaller, flight tank. If they were not careful and kept the tanks cooled to below 97 degrees F (critical temp for nitrous) then they would never have transferred any liquid nitrous, only gaseous nitrous. If they were measuring the fill rate by weight and not pressure in that situation, they could have over-pressurized the flight tank which would rupture and send shrapnel for 100's of feet in all directions.

My thoughts go out to all those involved.

+ - New DefCon Contest: 0wn the box? Own the box!->

It's based on Dragos Ruiu's "pwn to own" contest at CanSec, but we've extended it a bit. Defenders are asked to bring a hardened machine running at least two services, and if it's successfully compromised the attacker walks away with it.

We'd like to invite the Slashdot community to lug some gear out and test their defensive kung fu. More info, a list of entries, and the CFB (Call for Boxen) are at the contest thread on the DefCon forums."

+ - Autonomous insect cyborg sentinels

Roland Piquepaille writes "In a very brief article, AZoNano reports that nanotechnology is turning insects into flying cyborgs. Researchers from Cornell University have implanted 'microfluidic devices in insects before they hatch into fully grown flying creatures.' Of course, when they grow, these insects still carry the sensors. And if this works, they'll be used for monitoring and security surveillance. The article doesn't say that this project is funded by the U.S. Defense Advanced Research Projects Agency (DARPA) which has a full Hybrid Insect MEMS program. The goal of this program is to realize 'cyborgs with most of the machine component inside the insect body to provide stealthy robots' at low cost.Read more for additional details and a picture of one of these cybernetic insects."

Esther Schindler writes "The company is positioning this diminutive device (in late beta) as a consumer product. But with its out-of-the-box simplicity, says CIO.com's review, the Zonbu is an excellent choice for enterprise IT departments that want a Gentoo-based desktop Linux distribution, very little fuss and a price that won't raise eyebrows on an expense report."

+ - Hollywood training swedish police in Anti-Piracy

Submitted by
Oxygen
Oxygen writes "IDG.se reports on it's online newssite that representatives from the MPAA, FBI and the Swedish lobbyorganisation Antipiratbyrån have held seminars for swedish police officers (Swedish only) that are being trained in fighting piracy and copyright violations. From the article: "According to Bertil Ramsell, responsible for the course, the purpose of the visit was to give the invited speakers a chance to explain to the students what their organsation's purpose was. But in a report from the IIPA, the pupose was to educate students in anti-piracy." Educating is one thing, but the acronym MPAA doesn't really spell "objective" or "no hidden agenda" to me."

Regrowing Lost Body Parts Getting Closer All the Time 210

from the go-go-gadget-hand dept.
[TheBORG] writes "There are two stories on Yahoo! News about regrowing lost body parts. One is about regrowing lost fingers & limbs and the other one is about regrowing teeth. The story about regrowing lost fingers and limbs talks about the experimental use of powdered pig bladder to regrow fingers and eventually lost limbs for soldiers and others in need from information that Pentagon-funded scientists hopefully learn from studying the salamander. The story about regrowing teeth talks about how Japanese scientists used primitive cells and injected them into a framework of collagen. Once grown to a certain point, scientists implanted the growths into mice where the teeth developed normally."

Couple Who Catch Cop Speeding Could Face Charges 876

a_nonamiss writes "A Georgia couple, apparently tired of people speeding past their house, installed a camera and radar gun on their property. After it was installed, they caught a police office going 17MPH over the posted limit. They brought this to the attention of the local police department, and are now being forced to appear in front of a judge to answer to charges of stalking."
