Cool Parallax Propeller-powered quadrotor





Yet another IMU using Paralax's powerful 8-core Propeller chip. This one on a home-built quadrotor. Flying in IMU-assisted manual mode now, although I assume autonomous is just a matter of evolving the…

Finally! BlimpDuino code now in beta!

Jordi's done some heroic work squeezing the maximum out of the Arduino platform (with some help from Arduino co-founder Massimo Banzi. We finally have a code base that does everything it's supposed to.… Continue

New BlimpDuino code--much more efficient!

Jordi's been hard at work on the BlimpDuino code. Here's the latest version, which he describes as follows:



"Wow, a lot to explain! I added a lot of interesting functions, it will blow your mind ;-)



First I added a smart delay system. If you need to delay() something you can use the smart_delay(1000) function, and it will delay the value between the () and spend the time capturing IR packets rather than… Continue

DIY Drones stats update

Just a FYI: this site now does just under 200,000 page views a month, on nearly 50,000 unique visits. Traffic has quadrupled over the past year. On an average day, about 1,500 people will visit. Those that want to contribute join the site, and as a result we add about one member every two hours. We currently have 1,777 members.

BlimpDuino RC-mode code

If you want to fly BlimpDuino in RC mode (recommended! It's fun and a good way to learn the aerodynamics of vectoring thrusters), you'll need to run this code. BTW, we have beta units in the hands of testers now (sorry, no more units to give away at this time). If all goes well, we should have kits by the end of the year.

Upgrade your Arduino with more memory

Ladyada writes: Running out of space in your big Arduino project? Good news! Finally, after months of backorders, one can now buy the latest improvement to the ‘ATmega8′ line of chips: the ATmega328’s.

The ‘328 has 32K of flash, and 2K of SRAM. Basically its got the capacity of an ATmega32 but in a slimmer package. These chips are notable for their ability to drop-in… Continue

Air Force's New 'Killer Zombie' Drone

Armed Predator and Reaper drones have become the primary weapons in the fight against Pakistani militants. But they can be pricey; the Reapers come in at around a hundred million dollars each. Which is why the Air Force is working on a cheaper option: killer zombies.

Fossett wreck location?

The FAA has declared a no-fly zone over the location where the Fossett wreck was found. The Google Earth blog has mapped that into a KML file, so you can explore the location from satellite imagery in Google Earth (no guarantee that the imagery is recent enough to show the wreck, or high enough… Continue

It's on: Microchip vs. Atmel

Looks like there's a battle brewing in the embedded processor market. Microchip, which makes the PIC processor line that was the main microprocessor of the last generation, has made a bid to buy Atmel, which makes the AVR chip line that is the hot architecture of this generation (it's the family that our Arduino Atmega168 processor is part of). The bid is for $2.3 billion, but Atmel has rejected it and says it's not looking to sell. Is this a defensive move by Microchip, afraid that it will… Continue
