Solid-state joystick

Paul Gardner-Stephen writes: Early in the year, one of my colleagues, Damian, showed me one of these strain-gauge solid-state joysticks that they were using as part of the undergraduate engineering curriculum. Their goal was to teach the students how to read strain-gauges. But I immediately saw the applicability for making a no-moving-parts super-robust joystick for […]

App note: Joystick game controller reference design

Atmel AT01095:  Joystick game controller reference design This document (PDF!) shows the implementation of a joystick game controller based on the Atmel ATxmega32A4U microcontroller. This design allows users to control the mouse cursor and simulate left/right clicks from a personal computer (PC) or laptop via push buttons on the joystick of a game controller.

Competition Pro retro joystick USB adapter

Markus decided to reuse an old Commodere 64 Competiton Pro joystick, so he added a USB adapter to it. The retro joystick uses a simple interface over the D-SUB 9 connector, using one connection for each movement direction and one connection per button. He used a PIC24FJ64GB002 microcontroller to translate the native joystick interface to […]

Omnidirectional remote controlled robot

Markus shared his Omnidirectional remote controlled robot in the project log forum: Recently, I got interested in omni wheels, so I built this little robot. The robot has three pairs of omni wheels. I covered each roll of the omni wheels with liquid rubber (plastidip) to get better traction. I bought the cheapest servos I […]
