I’ve been a fan of airships for years and I think it’s great that their unique functionality is once again going to be used.
The airships – which have been dubbed Long Endurance Multi-Intelligence Vehicle (LEMV) systems – will be deployed in just 18 months.
“It is critical [for] our warfighters [to be] equipped with more enabling integrated ISR capability to tackle today’s and tomorrow’s conflicts,” explained Northrop spokesperson Alan Metzger.
“[So], we have designed a system with plug-and-play capability to readily integrate into the Army’s existing common ground station command centers and ground troops in forward operating bases.”
According to Metzger, the LEMVs are expected to be capable of sustaining altitudes of 20,000 feet for a three-week period.
Sounds like a great idea, this would solve the low (or non existent) wireless data rates that are found in the core of large buildings. Should be inexpensive to implement as well. So when can I get my LightFi lamp and alarm clock combo?
The objective of the initiative is to use visible light for communication between wireless devices and LED-based lighting fixtures. The LED-based scheme could also be used to communicate between automobiles, which are increasingly being equipped with LED lamps. The overall goal is to build new communication capabilities into all LED lights and reduce congestion in current RF bands.
Say what you will about the concept of Norway having ninjas but you have to admit that it could be very funny.
Kommandør Treholt & Ninjatroppen is the true story of how Commander Arne Treholt and his Ninja Force saved Norway during the Cold War. The story takes place in the time right before Treholt’s arrest on espionage charges in 1984, and reveals a spectacularly different version of our recent past than has been previously known.
Stunning 300fps video of robot carnage at the 2010 RoboGames. I never built a robot that was this tough and dangerous but I did see my fair share of sparks and flying metal at numerous events. If you have the chance and like ‘bot on ‘bot action make sure you seek out the next robot combat event near you.
Ah, the Marx generator. I have fond and not so fond memories of building my first one. It worked very well, I knew this because of the sort of out of body feeling I had when I got zapped by it. Anyway, it works by charging up a bank of capacitors in parallel and then are discharged in series. It will turn a few wimpy volts into something that will quite literally take your breath away. This site has a nice semi tutorial on how one is built. Go have a read and start scrounging in your junk box for some parts (mind you, keep a hand in your pocket to avoid making a dead short across your chest and through your heart. It’s not a sure thing but it helps)
I went to the bi-monthly hackerspace meeting last night. They had a guy there giving a talk about an open source 3D printer that he and his company is working on. I posted photos of it on Flickr. The thing is called ‘Cube.ly‘ and will, once finished, print 10cc of volume per hour, cost under $1000, takes a weekend to build, and is made of off the shelf parts. The frame is made of this stuff called ‘80/20′, think adult sized Erector set and the other bits like motors are available from McMaster-Carr or the guys that build the Makerbot (electronics).
