From Prototype to Production: Crowdfunding and Shipping the Modos Paper Dev Kit

What is it?

• Electrophoretic displays use charged particles suspended in microcapsules to form an image.
  • Reflective: They use ambient light like paper
  • Bistable: Once an image is drawn, it stays without power
  • Low refresh rates, but extremely low power draw.
  • Monochrome, grayscale, and color variants.
• Ideal for: reading, writing, and environments with natural light

Caster is an open-hardware

• High-refresh electrophoretic display controller that  supports multiple EPD screens (B/W and color) and supports multiple refresh modes:
  • Partial refresh for fast updates with minimal flicker
  • Grayscale for image fidelity
  • Full refresh to clear ghosting when needed
  • Fast mono for high-speed UI feedback

Who needs this?

• People seeking a balanced digital life
  • Want to reduce screen time, avoid overstimulation, and reconnect with the physical world.
• Those with health sensitivities
  • Suffering from migraines, light sensitivity, eye strain, epilepsy, or other screen-related conditions.​
• Designers and technologists
  • Seeking to build humane tools—devices that protect our well-being.

What becomes possible?

• A new category of devices and user experiences:
  • Computing devices that feel native on e-ink—no flicker, no redraws.
  • Calm computing environments that support focus, reflection, and slower thinking.
  • Minimalist tools for writers, developers, readers, and researchers.
