This Clapperboard Prints Movie Posters

The clapperboard is a device used in video to synchronize audio and video. Its role in movies is well known and its use goes back in one form or another to the 1920s. [Gocivici] is a big movie fan and created a clapperboard that is able to print out posters of recently announced movies when the clapper is clapped.

The poster is not a big, full color job, but rather a black and white one, roughly the size of a movie ticket. [Gocivici] keeps his movie tickets in a journal and wanted to be able to keep small posters in there along with them. A thermal printer is used to print the poster along with the title, the release date, and some information about the movie. In addition to the printer, the hardware involved is a Raspberry Pi, a switch, and an LED. The clapperboard itself is 3d printed and then painted. A bit of metal is used to keep the clappers apart and give a bit of resistance when pressing them together. A nice touch is a metal front, so you can use magnets to keep your posters on the board.

[Gocivici] has detailed build instructions up along with a video (available after the break) showing the printer in action. The 3d models are available as well as the code used to create the posters after grabbing data from TMDb. If you need your clapperboard to be as accurate as possible, take a look at this atomic clock clapperboard.

    1. It does what he wanted, which is the important thing.

      My thought is that thermal prints aren’t terribly stable long-term, which isn’t exactly compatible with the creator’s intent of having a memento. Then again, the ticket stubs he’s saving are also going to be thermal prints, so maybe it’s good enough with some extra care.
