Re: Home built intervalometer for LX3

Hi Heliodon,

Please send me a quotation on the Lumix LX3 with the complete Gent360 Servo (as shown in first images). Please e-mail to me at drzulmajid@gmail.com.

Motivated by a desire to use my LX3 atop a 10-meter, handheld pole I developed a mechanical intervalometer that is mounted to the hot shoe.

My objective: have the LX3 shoot at 10-second intervals while mounted on the top of a 10-meter-long pole or suspended from a kite.

The LX3 lacks a wired or infrared remote capability so my approach was to add a "psuedo finger" moved by a model aircraft servo. The timing and servo management are handled by a Gent360 Servo ( http://www.gentles.ltd.uk/gent360/order.htm ), a tiny circuit that rotates the servo arm through a 45 degree swing every ten seconds. The circuit and servo are powered by a 4.8 VDC 2/3 AAA NiMH battery pack.

The servo arm in ready (left) and trigger (right) states.

The three components are fixed to a small strip of aluminum that is mounted to the LX3 hot shoe and held in place by friction. Total weight for the intervalometer with battery is 2-1/4 oz. (64 grams). Works the charm.

Here is what the view is like from the pole with Panasonic's 0.75x wide angle adapter mounted:

This is my first test of the Panasonic Lumix LX3 with its 0.75x wide angle adapter using the 10-meter-long carp pole. This combination yields the equivalent of an 18-mm lens and provides quite the illusion of height. I used Photoshop's Filter > Distort > Lens Correction to remove a bit of barrel distortion.

The camera, adapter lens, and my intervalometer have a combined weight of just over a pound (460 grams). The pole seems to handle reasonably well carrying this weight. When the pole is in a vertical position I can handle it with one hand as in this image where I am holding the pole by its end and raising it above my head.
