About the author

Nik Reljin is a senior software engineer who likes building software that meets daily life. His projects cover IoT and home automation, machine learning that runs on local hardware, and making things: 3D printing and scanning, embedded keyboards and e-paper displays. He also gives retro and repurposed devices new work, and Orphan Parts Lens comes from that habit: old devices and loose parts given a second life.
