Bolex Intervalometer

[Don H Marks]

I put together a simple intervalometer for one of my Bolex cameras. 

The design uses a Radio Control Vehicle servo and a simple 'servo tester' box that cycles the servo at various speeds.

The servo cycles back and forth and pushes the frame release forward via a spring-loaded lever.

That's really cool - great idea!  I have made a few things with hobby servos before - but never thought of something movie camera related.

I found this guy a few days ago.  He is making a new animation motor for Bolex H16 and H8 models - and from what I can see - it can also maintain a steady 24 fps or 25fps too.  So, you can shoot sync sound it looks like:

That is very nice, thank you for the link. 

I built mine to try time-laps to see if I like it before buying gear I might not use much.
