Synchronizer (Electronic "Clapper-board")

When talking movies where just starting up,a problem arose.How would one be able to combine the image from the film,with the sound written in a studio sound booth? That's when the clapper board was invented.It's purpose is very simple.To provide a point by which image and sound can be synced on. That is achieved by having a wooden board with a stick on top.That way when it's hit,all the editor has to do is find the first frame that the clapperboard is closed,and the first frame on the audio track that the "crack" sound is heard. Even though tecnology has improved since the 30's the closest thing to an electronic clapper board that exists is a plastic board with LED's on it,that display the timecode. Synchronizer is completely electronic.

step 3Soldering

Now it's time to solder your connections.Solder the resistors to the positive leads of the LEDs and then all the positive leads from the 2 LEDs and the buzzer to one end of…

step 4Sealing it up

Just place the other end on top,and seal it up,with either hot glue,or electrician's tape. I wanted to use black gaffers tape personally,so that it wouldn't look that bad,b…
