AXIOM Remote
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.

AXIOM Team Talk 14.3 covered AXIOM Remote development progress: [1]
| Essentials | Good to Have | Luxury |
|---|---|---|
| a few Status LEDs | single color LED under most buttons (transparent) | RGB LED under every button (transparent) |
| power supply from camera | power IN connector | own battery mount |
| wired operation | wireless operation option | |
| turn LCD into touchscreen (can be disabled in menu) | ||
| Control all AXIOM related functionalists | Control active lens mount related functionalists | Remote Control other cameras and devices (LANC, USB, DSLR Shutter Release, etc.) |
| 2x Rotary Knobs (infinite rotation) | additional slider/fader knob | Force Feedback Rotary Knobs (built-in microstepper motor) |
2 Status
August 2018
- Printed circuit boards have been designed and populated.
- Button options are being tested.
- UI has been designed but software work is still required (please see this page's footer if you'd like too assist).
- CAD for aluminium milled enclosure parts is ongoing.
The first development prototype of the AXIOM Remote (a device with buttons, dials, rocker switches and a small LCD to change/control any camera parameter) printed circuit boards has been designed and routed, ordered and received. Another unit will be assembled shortly so that software development can commence. 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.
