Light Phones

Light Phone is an experiment in hyper-local communication. Inspired by the ‘Astro Phone’ or ‘Light Telephone’, devices developed in the 1960s that transmit sound via modulated infrared light, documented in Lori Emerson's Radical Technology Sourcebook (2025), the project repurposes disused remote controls into short-range communication devices. Interested in the distinctive grain of infrared transmission, Light Phone will create a network of low-power, DIY, line-of-sight telephones that future Wave Farm residents can use to communicate across the landscape.
