Flowshutter

Homepage • Documentation • Discord • Report bug • Request feature

Flowshutter is a custom camera remote. When used in conjunction with readily available hardware, this results in a flexible and reliable external camera motion logger for Gyroflow. It can provide precise synchronization of camera video recording and motion logger (betaflight/emuflight FC) recording.

It was designed to be used with the Gyroflow software to provide you one of the best open source video stabilization experiences.

Features

Flowshutter has the following features:

'1-click' - (1) start/stop camera recording and (2) arm/disarm FC, via one click
Camera recording start/stop control
FC arm/disarm control
OLED display

with many more features on the way!

Supported Hardware

Currently we are working with a manufacturer that will produce flowshutter hardware. We will disclose more relevant information in the future.

At the same time you can try to DIY your own flowshutter hardware. We have two open sourced designs:

Credit card sized design:

FC sized design:

Compatible camera protocol/trigger mechanisms

Sony MULTI Terminal protocol
Momentary Ground
3.3V Schmitt trigger
(WIP) 5V Schmitt trigger
(WIP) Sony LANC protocol
(WIP) HDMI CEC protocol

For more information about support camera list, please check the list on the documentation website.

Compatible FC

FC is short for flight controller, more specifically with betaflight/emuflight running on.

flowbox (highly recommended)
modern FC with BMI270 gyroscope (recommended)
any other FC that support CRSF protocol

Development Guide

Flash micropython firmware

The micropython firmware we used is v1.18, You can find a copy in the /tools directory. Also, a uPyCraft windows version is also provided in the /tools directory. You can try to use that to flash your ESP32 without the help of ESP-idf.

Set up environment

Visual Studio Code with Pymakr extension is recommended.

Install node
Manually install Visual Studio Code 1.64.2
Install Pymakr extension in Visual Studio Code
After pymakr correctly loaded in Visual Studio Code, update Visual Studio Code to the latest version (currently 1.66.1)
Manually install Pymakr (v1.18.0-beta.0 or newer) extension in Visual Studio Code
Edit Pymakr's global settings that add "wch.cn", to "autoconnect_comport_manufacturers"
Modify content of "address" to "address": "",
Edit address in pymakr.config
Pull flowshutter code from https://github.com/gyroflow/flowshutter
Then you can connect and upload the flowshutter code
