Chair Control Breakout

Copyright 2018 SuperHouse Automation Pty Ltd <www.superhouse.tv>
Designed by Jonathan Oxer

Connects between an electric wheelchair input device and the chair controller, so that the input device can be read by an Arduino and redirected to another system.

The output can be isolated so that the chair won't receive the input signals, preventing it from moving while the input is being used for another purpose such as controlling a computer or remote control device.

The Arduino can send the output to either a connected USB host such as a computer, or to the trainer port on a Flysky radio remote control so the wheelchair controls can be used to fly a drone or drive a remote control car.

A second input device can be connected simultaneously, so that a total of four axes can be read. For example, a pair of low-force hall-effect joysticks attached to a wheelchair could be used to fly a drone.

Features:

  • 2 x input device connections.
  • 1 x input device pass-through output
  • 1 x mini-DIN 4 pin output for PPM connection to Flysky transmitter
  • Mounting headers for an Arduino
  • Derives 12V power from the host wheelchair controller
