Flickr member six million dollar dan made clever use of a spring clamp for his garden timelapse camera -
clamp is standard spring clamp. it actually has a hole in it already that fits a #1/4-20 screw. #1/4-20 is standard size for camera mounts (in the USA at least). I added the red thumbscrew.
Thanks Dan – always good to have hacks like these in your arsenal.
