I have a few suggestions on the hardware design of the PPM:
– There’s no built-in or removable lens cover?? This is a real problem for this device, because the lens can get dirty or scratched if not stored and handled properly.
– Why in 2020 is the remote using IR rather than Bluetooth?? It’s a pain to have to get behind the projector to use the remote, if you’re sitting next to the projector. At least could an Android app be added that mimics the remote functionality from your phone, over Wifi or Bluetooth? (Chromecast has an app like this.)
– I appreciate the compact size, but why is this projector so heavy? Is that mostly battery and glass weight? Are there any lighter materials that could be used for the next revision?
