Welcome to the Hackberry Wiki !

Hackberry is an open-source myolectric prosthesis (Prosthesis controlled by muscle sensors placed on the arm to control it) developed by Exiii for people with disabilities hand to regain autonomy in everyday life: social, professional, transport, ...

These prototypes are still limited for everyday use in comparison to the models on the market, but they have the following characteristics:

• The total cost of the prosthesis is less than 1000€ (10 000 to 70 000 € on the market)
• The main parts (fingers, palm, socket) are made with a 3D printer
• Parts plans, material list and manufacturing tutorials are online so that the prosthesis can be made and contribute to the development of the prosthesis by sharing these results (open source)

Its goal is to federate a team around the construction of a lower limb prosthesis at low cost with standardized and open source parts. They are easily repairable and therefore accessible to people with limited financial resources. He wants to help emerging countries that do not have access to prosthetic equipment.
