Tutorial · ptrbrtz/razor-9dof-ahrs Wiki - Nightly Building an AHRS using the SparkFun "9DOF Razor IMU" or "9DOF Sensor Stick" Razor AHRS v1.4.2 — See the Changelog Overview Intro This tutorial describes how to put together an Attitude and Heading Reference System (AHRS) which does not cost much (around 140$/120€) and works very well. It can be used in projects requiring real-time 3D orientation tracking such as RobotsUAVs and autonomous vehiclesImage stabilization systemsHead-tracking, e.g. for binaural audio applications (the SoundScapeRenderer - a spatial audio reproduction tool - has Razor AHRS support built in)

Camera Interface Specifications MIPI CSI-2 and MIPI CSI-3 are the successors of the original MIPI camera interface standard, and both standards continue to evolve. Both are highly capable architectures that give designers, manufacturers – and ultimately consumers – more options and greater value while maintaining the advantages of standard interfaces. Evolving CSI-2 Specification The bandwidths of today’s host processor-to-camera sensor interfaces are being pushed to their limits by the demand for higher image resolution, greater color depth and faster frame rates. But more bandwidth is simply not enough for designers with performance targets that span multiple product generations.
MEMS IMU - Nightly Based on its 45 years of experience in inertial systems technology NG LITEF designed its new generation MEMS (Micro Electro Mechanical Systems) technology sensors. The µIMU is based on this newest technology. It is a full inertial measurement unit containing 3 MEMS rate sensors, 3 MEMS linear accelerometers, the related electronics and the power supply in one sealed, robust housing. With its small size, easy to integrate interface and excellent performance the µIMU is the perfect measurement unit for all applications like attitude heading reference systems, flight control and guidance systems or for the stabilization of cameras, antennas and other instruments on moving platforms.

Flying Cameras Ambarella A12D - Flying Camera SoC The Ambarella A12D Flying Camera SoC targets mainstream 1080p to 4K Ultra High Definition (UHD) flying cameras. The A12D is a system-on-chip solution that integrates an advanced image sensor pipeline (ISP), an H.264 encoder, and a powerful ARM® Cortex™-A9 CPU. Targeting the next generation of connected flying cameras, the A12D chip delivers up to 4K video recording at 30 frames per second while streaming a second, live, mobile-resolution video over a WiFi network for preview or sharing. A hardware-accelerated 3-dimensional image stabilization engine with rolling shutter correction enables stable recording during windy or high-motion conditions. The A12D 800-MHz Cortex ARM A9 CPU provides ample performance for advanced camera, flight control, and streaming applications.
LN-200 FOG Family Advanced Airborne IMU/AHRS - Nightly The LN-200 inertial family of fiber-optic gyros (FOG) offers the lowest accel/gyro bias, lowest random walk and the highest mean time between failures (MTBF). The LN-200 is a small, light weight, highly reliable, state-of-the art, fiber-optic, all-altitude, strap down Inertial Measurement Unit (IMU). The LN-200 has three solid-state fiber-optic gyros and three solid-state silicon Micro Electro-Mechanical System (MEMS) accelerometers in a compact package that measures velocity and angle changes in a coordinate system fixed relative to its case. Digital output data of incremental velocity and incremental angle are provided to user equipment over a digital serial data bus.
Achims Homepage - PPM Switch - Nightly The I2C servo switch has been applied successfully for several years in various prototypes of the Flobo project. Despite its functional reliability its disadvantage is an extremely limited operating range. The cause is most likely interference of the main computer Gumstix, which is electrically coupled into the I2C bus and thus affects the sensitivity of the R/C receiver. In an appropriate test much greater distances were achieved when the Gumstix was switched off, or at least in idle mode (no read / write on flashdisk). The main requirement for next version of the servo switch therefore was the electrical isolation between the autopilot and R/C circuit and hence a significant increase in range.

Driving a high current DC Motor using an H-bridge - Northwestern Mechatronics Wiki - Nightly Overview An H-bridge is a circuit configuration commonly used to control the speed and direction of a brushed DC motor. The convenience of an H-bridge is that a low current digital signal can be used to control a high current motor (or other device). Full H-bridge circuits capable of a few Amps can be purchased in convenient IC packages (see PWM and H-bridge chips). The H-bridge described in this write-up is capable of currents up to about 40A at 24V, but requires the assembly of a PCB.
fpvkiwi / Channel Wizard / wiki / Home — Bitbucket - Nightly Channel Wizard increases the number of available channels in a radio-control system. This is done by modifying the PPM stream before the radio module sends it over the air. The device isn't limited to a particular radio brand.
