We missed [iliasam’s] laser text projector when it first appeared, perhaps because the original article was in Russian. However, he recently reposted in English and it really caught our eye. You can see a short video of it in operation, below.
The projector uses raster scanning where the beam goes over each spot in a grid pattern.
The design uses one laser from a cheap laser pointer and a salvaged mirror module from an old laser printer. The laser pointer diode turned out to be a bit weak, so a DVD laser was eventually put into service….The post Text Projector With — You Know — Lasers appeared first on FeedBox.
