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…
BlimpDuino is in the hands of beta testers, so we're doing some last minute tweaks. The current code works on boards version 431 and up (don't ask about the numbering schemes--they're based on internal versions. When we release the commercial board, it will be called V1.0 as… Continue
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. Here's the code. It works with any version of the board… Continue
If you've been wanting to move to a >1Hz GPS receiver but were holding out until a retail version of the awesome U-blox chipset was available, today's your lucky day. Sparkfun has just started selling the 4Hz GS406, which uses a helical antenna,… Continue
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
For those of you interested in learning about embedded computing with a modern, open source platform, the new Arduino Starter Kit from O'Reilly looks great. $89 buys a lot of useful stuff.
OReilly's also releasing a new book by Arduino co-founder Massimo Banzi that looks… Continue
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.
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.
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
Lots of cool sensor and other parts for your Eagle PCB-designing needs in SparkFun's new batch of additions to the Eagle component and footprint library. Now up to 275 devices. A must-add if you use Eagle. Get them all… Continue
While we debug some production glitches in ArduPilot, work on ArduPilot Pro (the dual-core board with built-in stabilization) is moving ahead. Jordi's working on the first production candidate, which is shown above with the FMA thermopile sensor head, which we're using for testing. Click on the picture for a bigger… Continue
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.
Visit Davis-Monthan Air Force Base in Tucson, Arizona, and you'll see rows upon of… Continue
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 resolution).… Continue
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
Dean has posted a pdf spec sheet for AttoPilot. Here are the basics:
Specifications and Features:
