About The Project

I saw few options for open-source flight sticks out there. Commercial options are exceedingly expensive. I strive to build a full-featured and high-quality Flightstick with a target BOM cost from 150-200€. It is not meant to be the cheapest joystick, but it does aim to be the most attractive option for open-source and DIY enthusiasts.

BOMs, parts lists, and documentation for various gimbals and 3D printed joysticks are sparse at best. I aim to include an extremely comprehensive requirements list, drop-in replacement part list, etc... so that this will be as accessible to everyone who has interest in building their own stick.

This is very open to all contributions and improvements from the community.

Getting Started

This process is hopefully as painless as possible. It will take hours of printing, some of soldering, assembling, and testing to make sure everything works. In order to have the most quality product as possible and respect the supply chain issues everyone has, I chose the cheapest, most available chip that is also easy to solder onto the PCB, but also has integrated USB so you don't need to search for an elusive USB HID FTDI chip. Everything can be assembled and disassembled repeatedly in principle (minimal/no direct screw to print interfaces)

I also added alternate electronics headers so that one can use an STM32 Bluepill in place of the USB, MCU, and power components if you don't like soldering. The upside to this is that I may be able to make a firmware profile compatible with FreeJoy in the future. I will have to look into compatibility with I2C peripherals in FreeJoy. If one is using the embedded MCU, then it will require the custom firmware. Everything should be plug-and-play with no drivers needed because proper USB descriptors will be developed.

Prerequisites

This is a very general list of the materials you will need to assemble and program the stick. All BOM items are assumed to be ordered and received.

• 3D Printer
• Soldering Iron/Soldering Station + solder + flux paste/pen
• Microscope for soldering
• Hex key drivers and philips 0 screwdriver (dependent on your bolt choice)
• Mechanical and electrical BOM materials
• Manufactured PCBs
• ST-Link V2 or STM32F0 disovery board + jumpers for programming MCU
• USB-C cable
• PC running Linux or Windows
• STM32CubeProgrammer or PlatformIO on VSCode/Code-OSS

Roadmap

• 3D printed shells and parts designed
• 3D printed parts fully printable and assemblable
• PCBs made in single panel and multi-board configurations
• Windows and Linux compatible firmware
  • Firmware can detect a TM/Virpil grip and fall back into "basic mode"
  • Drivers if needed
• Assembly Instructions
  • Video
• Button binding instructions
  • Video
• BOM for electronics
• BOM for mechanics
• Cost estimates for 1 american, 1 european, and 1 chinese manufacturers
• Documentation
• Possibly selling electronics kits or assembed kits?
