AXIOM Remote Concept Rendering 2018 - Note: Design is subject to change as improvements are made.

1 Project Overview

This device and its associated software, is designed to be a comprehensive remote control unit for the AXIOM range of cameras.

As with all software & hardware that is pre-production the information contained on this page is subject to changes.

AXIOM Remote was funded as a stretch goal in the AXIOM Beta crowd funding campaign and is still in development. It features push-buttons and switches as well as 2 rotary encoders (also with push-button function) that can be used to control a wide range of camera parameters like shutter speed, gain, overlays, FPS, gamma curves etc. To keep everything as flexible as possible the buttons next to the LCD have dynamic functionality as their commands are displayed next to them on the LCD. Switches on the side allow locking of each individual dial wheel or all buttons on the AXIOM Remote.

Force Feedback for the two dials with two small built-in micro-stepper motors to allow feeling the settings (like min, max reached) without looking at the display was considered but deemed to complex/expensive for now.

The AXIOM Remote is based on a 2.8" LCD screen (for showing status information, camera parameters and navigating through menus, no live video) and a PIC32 micro-controller. The connection between AXIOM Remote and an AXIOM camera will be a flexible (preferably spiral) cable with solid connectors. Expansion slots (with GPIO) shall allow easy future addition of new buttons/knobs/wheels/controllers/interfaces.

2 Status

August 2018

  • Printed circuit boards have been designed and populated.
  • Button options are being tested.
  • UI design is ongoing but further software refinements are still required (please see this page's footer if you'd like too assist).
  • CAD design for aluminium milled enclosure parts is ongoing.

2.1 PCB Version 0.9

The first development prototype of the AXIOM Remote printed circuit board (V0.9) has been designed and routed, ordered, received and populated. This first version is not meant to be perfect (for testing we just used a simple 6x6mm Alps push-button type - not the more expensive ones with better haptic feedback) but should provide a good foundation for developers to focus on ensuring that the menus work and how to create an intuitive and pleasant user experience when operating an AXIOM camera.

2.2 PCB Version 0.9

Considerations/Ideas for the next version:

  • Do we really need a second rotary knob? For menu navigation and the changing of parameters so far we saw no use for it designing the UI.
  • Add flash memory for storing of images? So far we have not exceeded the PIC32s internal storage memory but if we want to make the internal help system more extensive with lots of added illustrations/images it might be required to add more flash storage.
  • Remove left side rocker switches? So far we have not found any function for them. They are prone to being switched accidentally as they stand out from the device quite far. Having buttons/switches on the left side of the remote prevents it from being attached on that side though.

6 TODO, next steps

  1. pick buttons, rotary encoders, etc components, collect datasheets and extract documentation about each components footprint and positions here
