- The page says the cold-plasma component is still in development and that ozone is measured during testing.
Field notes
The page lists off-the-shelf internal components, including an ESP32-S3 controller, lithium-ion cell, two fans, and wireless charging. It says the camera filter passes two bands and that images appear on the device’s own display. A separate cold-plasma function is marked as in development; the page notes ozone production and describes testing on lab plates.
