TiaLinx has announced the launch of the Phoenix50-H. The quad coaxial mini-copter system is capable of performing multiple functions such as detecting movement or breathing of a hiding person in a compound from a sloped roof. The mini-copter can be remotely controlled at extended standoff distances of more than multiples of 100 feet from ground or an airborne asset to keep the operators out of harm's way.
The lightweight and agile mini-copter with… Continue
STMicro has done it again... this time readying their ARM Cortex-M4 MCU (with hardware floating-point, DSP instructions and compatibility with Cortex-M3) for production in early 2011. In addition, they're also expanding into the F-2 series, which features an adaptive real-time memory accelerator to achieve a performance of 150 Dhrystone MIPS when executing code from flash at 120MHz (the maximum possible for the Cortex… Continue
The venerable STM32 line of processors, featuring the ARM CORTEX-M3 core, have now been extended to include up to 512KB of flash memory on-board! That's a huge bonus for those Nav/AutoPilot projects that want to feature a lot of code!
Speaking of servos (the topic of my prior post), the GS-1 gyro server self-stabilizes (in one axis only)...
I'm curious... has anyone used a pair of these to construct a self-stabilizing pan/tilt gimbal for their aerial shots (plane or copter)? It would certainly make for less parts and wiring, being that servos will still be required to do the job (so why not cram the gyro in the servo… Continue
In various groups and blogs I peruse on here, there's been talk about I2C control of servos (as opposed to standard PWM). This certainly solves several problems, as it allows one I/O port (I2C) to service over a hundred servos with ease. With some built-in intelligence, the servo itself can… Continue
I'm partial to the STM32 (ARM CORTEX-M3 based uController) line of uControllers, not only for their hardware mul/div instructions, but also for their ability to have the ADC converter continually scanning and pushing to memory its conversion results from a series of analog devices.
