Meet the Makers: Monoculite

Monoculight is an open and freely available 3D printed functioning eyeball that works using the same principles as your own eyes. The model is fun and easy to build and creates an inverted image on the “retina screen” of whatever you point it at. Materials will be on hand to build your own “Mini-Monoculight” for free. is an open and freely available 3D printed functioning eyeball that works using the same principles as your own eyes.

See for yourself how your own eyes work!

On his Thingiverse page, inventor Art Davis says he’s most proud of how Monoculight can be used to inspire self-directed technology education.

Just put a Monoculight in someones hands and see what happens:

  • Experience how basic lens technology works in a very tactile and understandable way.
  • Press a button to make bright lights. Pop the Monoculight open and see the very simple circuit technology at work.
  • Confused about why the image is upside down on the retina in Monoculight while we don’t see things upside in real life? It’s easy
    for our brains which are better image processors than any technology ever invented.
  • Light up Monoculight in the dark and observe first hand additive color mixing which is the principle behind the ubiquitous display technologies we use every day.
  • Curious about that display technology? Open Monoculight, place it near a display and see the RGB pixels firsthand.

The Troy Mini Maker Faire is this Saturday, August 27, from 11 am to 6 pm. Get your free tickets  now (or just come by) and join us on to meet all our Makers. We look forward to seeing you on August 27!
