I'm looking for a tiny, cheap laser projector that just outputs texts from a terminal. That's it. The simpler, the better. The output can be low resolution pixels or laser traced lines.
Like the laser part of a laser projection keyboard.

1Do you have a specific reason for requiring a laser projector? Any requirements for resolution? If laser, you could either use a projector that displays pixels or traces the paths of characters; Any preference there?– RomenMar 7, 2020 at 19:19

@Romen No preference, but a laser that traces the path is better suited for the task.– H2ForgeMar 9, 2020 at 6:25

1) What's the measured ambient lighting where you wish to use the device? There's an app for that: google.com/search?q=android+app+measure+light+level 2) Do you have full spectrum colour vision (not everyone does, ya know)?– K7AAYMar 17, 2020 at 18:44
