The limited phone provides the basic needs for your non-typical phone user, the ability to make phone calls. The goal of this project is to design and fab an open source phone that is extensible and provides a limited human interface. Interface elements may include: * Slow refresh e-ink display * thumb wheel with press button * on-off switch or button * speaker * microphone * raspberry PI zero ports * Touch/gesture surface ( potentially ) The project is on-going and I accepting collaborators.
