Electronic Film Clapper v1.2

This project came about because I needed a way of marking Video and Audio files for editing. I didn’t wish to use a full size clapper for the job so I designed my own device. I chose to try the idea out on an Arduino Uno, but realising that an ATMEGA328 was a little excessive for such a trivial task, I moved over to a Digispark clone purchased on eBay. This board utilises the ATTiny85 MCU.

The requirement is to have a visual and audio que that is apparent upon editing the separate streams together. I intend to film at 25fps (Frames Per Second) so I determined that a 25ms pulse of light from an LED and an audio pip would fit into a frame. The pulse period is easily changed in firmware, as is the audio tone of the ‘pip’, although I found 4300Hz is pretty optional for my use.

The prototype works well and boards have been ordered from Hackvana.com Once proved, all design files will be available from here.
