If, like me, you’re up on your “Active Denial Systems,” you probably know that such systems were (thankfully) relegated to slow-moving earth-crawlers.  Well, leave it to the Pentagon to give these non-lethal microwave emitters wings…er, rotors:

The Pentagon’s enthusiasm for non-lethal crowd-control weapons appears to have stepped up a gear with its decision to develop a microwave pain-infliction system that can be fired from an aircraft.  The device is an extension of its controversial Active Denial System, which uses microwaves to heat the surface of the skin, creating a painful sensation without burning that strongly motivates the target to flee. The ADS was unveiled in 2001, but it has not been deployed owing to legal issues and safety fears.

Nevertheless, the Pentagon’s Joint Non-Lethal Weapons Directorate (JNLWD) in Quantico, Virginia, has now called for it to be upgraded. The US air force, whose radar technology the ADS is based on, is increasing its annual funding of the system from $2 million to $10 million.

The transmitting antenna on the current system is 2 metres across, produces a single beam of similar width and is steered mechanically, making it cumbersome. At the heart of the new weapon will be a compact airborne antenna, which will be steered electronically and be capable of generating multiple beams, each of which can be aimed while on the move.

This Drawdio kit can be yours for $17.50 at Adafruit Industries. Creator, Jay Silver talks about Drawdio:

Imagine you could draw musical instruments on normal paper with any pencil (cheap circuit thumb-tacked on) and then play them with your finger. The Drawdio circuit-craft lets you MacGuyver your everyday objects into musical instruments: paintbrushes, macaroni, trees, grandpa, even the kitchen sink…

One day I bought a “harmonium” kit at the street market in Bangalore. I hacksawed the keyboard off to make the first ever Drawdio circuit. We played with it at a local school in the slums using plants, water, our foreheads, etc. My friend told me graphite would work too. Meditating on it, I realized the Drawdio circuit should be literally attached to a pencil to “draw audio,” and that’s where the name came from: Draw + Audio.
