Fixed the video problem, it wasn't published yet LoL! (I myself could watch it of course).
Quick facts for the AT-01, Lightbringer:
- Pill: hollow, small, with very low height driver shelf until you knock on the emitter board, ≈5mm. Emitter retaining device: circular metal sheet piece, much like those $2 SK68's.
- Lens: plastic, ∅28mm OD, ∅20.5mm ID; focal lenght must be somewhere a few millimeters above ≈11.5mm, which is the head travel lenght.
- Bezel: ∅22mm gap.
- Head: wobbly (single o-ring).
- Emitter: unidentified angry blue specimen. :facepalm:
- Driver: typical custom micro-controller unit with small FET and a couple of current limiting resistors.
Received a few days ago, didn't payed much attention to it for reasons. May take a pic or two some other time.
