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.
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.
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).
This projects is intended for those who would like to get started with OpenCV and stereo vision. I created a simple StereoVision C++ class that simplifies the development of a 3D calibration and vision system.
