Just the bare bones!
They don't get any simpler than this!
Brooxes Simplex is just a lightweight manually-aimed camera frame and Picavet suspension system, intended to carry a compact point-&-shoot camera. Use it with a camera that has its own built-in intervalometer, or with a CHDK-converted Canon, or with an infrared-triggerable camera with a James Gentles external interval timer such as the gentLED-Auto shown here.
Brooxes Simplex Kit
includes two Brooxes Utility Frames,
Picavet Cross and line,KAP-Klips™, and hardware.
(Shutter trigger and camera not included)
