Arduino code for simplified Kalman filter. Using a 5DOF IMU (accelerometer and gyroscope combo) Arduino code for simplified Kalman filter. Using a 5DOF IMU (accelerometer and gyroscope combo)

This article introduces an  implementation of a simplified filtering algorithm that was inspired by Kalman filter. The Arduino code is tested using a 5DOF IMU unit from GadgetGangster - Acc_Gyro . The theory behind this algorithm was first introduced in my Imu Guide article.

A Guide To using  IMU (Accelerometer and Gyroscope Devices)  in Embedded Applications. A Guide To using IMU (Accelerometer and Gyroscope Devices) in Embedded Applications.

This article discussed the theory behind accelerometer and gyroscope devices. It shows a simple  Kalman filter alternative, that allows you to combine accelerometer and gyroscope data in order to obtain more accurate estimates about the inclination of the device relative to the ground plane.

Accelerometer benchmarks. Part 2:  LIS331AL and DE-ACCM2G (ADXL322) . Filters, amplifiers and vibration response. Accelerometer benchmarks. Part 2: LIS331AL and DE-ACCM2G (ADXL322) . Filters, amplifiers and vibration response.

In this article I am testing another accelerometer from ST - LIS331AL. I am also touching the topic of filters and vibration response.

Accelerometers reviewed and tested. Part 1: DE-ACCM2G (ADXL322), LIS244AL, Pololu MMA7260QT Accelerometers reviewed and tested. Part 1: DE-ACCM2G (ADXL322), LIS244AL, Pololu MMA7260QT

This article is the first in a series of reviews of MEMS devices (gyroscopes, accelerometers). I start by testing 3 accelerometers side by side and testing their performance: Dimension Engineering DE-ACCM2G (ADXL322), LIS244AL, Pololu MMA7260QT.

New and Updated Motion USB Gamepad: wide accelerometer and gyroscope support, configuration utility software New and Updated Motion USB Gamepad: wide accelerometer and gyroscope support, configuration utility software

I have received some feedback from my readers regarding my first usb gamepad project , so for the past few weeks I was working on a new imrpoved design.    There are plenty of new improvements that I hope will address many of your requests. The new device supports a wide range of gyroscopes and accelerometers that can be configured using  Configuration Utility for Windows. Have a look at this article as it features new suggested schematics as well as a full feature log. Firmware and configuration utility are free to download for private use.

This article is a continuation of my series of SMT experiments. It describes the process of creating a custom PCB and reflowing a SMT device in home conditions.

Build a 8A (4A per motor) dual motor driver for under $10. Introducing OctoDriver - poor man's motor controller. Build a 8A (4A per motor) dual motor driver for under $10. Introducing OctoDriver - poor man's motor controller.

This article describes how to create an inexpensive and easy to build motor driver that can drive two DC brushed motors. The driver holds  4A per motor  with  8A peak per motor. I'm including the circuit schematic and photos of a sample build on a perforated proto-board. Watch videos of motor controller in action mounted in my new wireless robot.

Use macro definitions to simplify work with I/O ports in C (MICROCHIP PIC/ATMEL AVR) Use macro definitions to simplify work with I/O ports in C (MICROCHIP PIC/ATMEL AVR)

This article describes a series of techniques that facilitates defining and programming I/O ports in embeded C with the same ease you do these task in PBASIC/PicBasic. Macro definitions and sample code is given for PIC C18/C30  and  gcc-avr (ATMEL MCUs).
