Balancing Two-Wheel Scooter

admin — Fri, 04 Jun 2010 22:13:06 +0000

This low-cost ATmega32-based balancing scooter can carry 90 kg at a speed of 15 km per hour over a distance of 10 km. The project uses “dynamic stabilization” for control. The project is equipped with a Gyro (Sensor for the angle rate), an acceleration Sensor ADXL311, a microprocessor AtMega32 and high power electric motors [...]

Microstepping Bipolar Stepper Motor Driver

admin — Mon, 17 May 2010 00:52:06 +0000

This project is the implementation of a low-cost, high-performance bipolar stepper motor driver. This driver was designed for the hobbyist who is retrofitting a piece of equipment for CNC operation using one of the inexpensive and readily available interpreter programs. Generally speaking, these programs are capable of reading the GCode output from a CAM [...]

This project show you how to build Unipolar Stepper Motor driver for high current. The driver able to handle up to 20A. The main component in this driver is L297. While the driver circuit is more or less taken from the L297 datasheet. More features from the project are : Handles a maximum of 100V, [...]

Unipolar Stepper Motor Driver

admin — Wed, 30 Dec 2009 19:45:26 +0000

This project enables you to drive two unipolar stepper motor or eight electric light bulb or DC motors. There are eight DC power switch you can open or close through PC parallel port. For safety reason, digital interface to PC uses optocouplers. You can connect up to six circuits to a single LPT, driving up [...]
